      Xiaomi TV4 : Hanged up at the First Wall Paper Screen



      8 February 2018

      Introduction

      Xiaomi TV4 restarted suddenly when browsing using Google Chrome or when trying to play certain foreign movies.   Sometimes,  the TV can restart itself  smoothly but sometimes,   the TV might just stuck at the first Wall paper Screen,  refusing to move further.  This article propose a method where one can resolve this  problem.

      Why Xiaomi TV Restarted?

      There is no explanation or warning.   But many observations suggest that Xiaomi TV does not like the default video players specified by the foreign movies.  May be such action triggered certain hardware interrupts that cause the TV to restart or hang up. The other possibility is that we have downloaded/uploaded too many apps and some of these apps are not friendly to Xiaomi TV's OS.

      What to do Next?

      When the TV has a hangup,  it will not respond the the remote controller nor the white start/stop button underneath the TV screen.    The only recourse is to pull the  TV’s power plug.   Sometimes,  the stubborn hang up just refuse to go away.  Fortunately,  Xiaomi TV has a recovery mode in which one can do a hard reset.

      How to do a Hard Reset?

      1. Pull the power plug off the TV and wait for about 20 seconds
      2. Push and hold the the “confirm” and “Restore” buttons at the same and plug back the power supply;
      3.  
      4. The TV will try to start.   If it does not,   press the white big button just underneath the logo "Mi" in the center of  the TV screen with the other hand or get someone to help; 
      5.  The TV will go into recovery mode with the following screen appearing.  Quickly release the "confirm" button first and then the "Restore" button when this recovery screen appears.



      1. Select “Wipe Cache” to wipe and clean the caches stored in the memory and then select “Reboot”.  Note that sometimes,  a rebooting will already solve the stubborn hang up without clearing the caches;
      2. If the TV again refuse to restart normally,   repeat 1 to 5 and select also “wipe user data”.   
      3. Note that there may be a need to pair the remote controller after the restoration. 

       Note:  it is not advisable perform  "Wipe All Data" especially when one has rooted the TV before.
      This will also clear the newly installed APKs that is not native to the TV.  Make sure one has a copy of the installed APK for restoration.

      What is Bollinger Band Indicator?


      Bollinger Band is actually a derivative of moving average indicator. Instead of just plotting a simple moving average (usually 20-day), it also plots the upper and lower values of the moving average which is two standard deviations away from the simple moving average as shown in the attached graph.

      It is a mathematical expression to express the deviation of the values from a mean average. The explanation could be complex but in simple term, standard deviation is just a mathematical tool that can be used to tell what is normal, and what is extra high or extra low of the historic stock price or index. In the above example, the normal 20-day index of STI is ......, the extra high index is .... and the extra low index is ... on 20 Jan 2009.




      What the use of Bollinger Band?


      Traders often use Bollinger Band to track the movement of the stock or index. This is because it can foretell the extra high and extra low prices based on past historically prices.

      Xiaomi TV: To Root or Not To Root

      3 February 2018

      Introduction 


      This is always a frequently asked question.  This article will attempt to give some answers but the decision to root or not should rest with the users  

      What is Rooting? 

       It is actually a jargon term used for “Jail Breaking”.  It is a term used to describe the removal of the   restrictions often installed in smart device for some reasons. Take Xiaomi TV for example, the manufacturer is forcing every user to watch a 20-second advertisement whenever one starts up the TV.   Because of this,  some users went "rooting".    There are also others who want to remove the restrictions so that they can watch free movies.

      How To Root?

      Rooting involves a change in the software stored inside the Read Only Memory (ROM).  This ROM is actually non-volatile flash memory microchip that one can program and re-program to control  the operation of smart devices.  It contains the operating system (OS) and the manufacturers usually do not recommend one to modify and change the software in the ROM.

      What are the Main Advantage of Rooting? 

      For Xiaomi TV, besides having the ability to remove the 20 seconds advertisement at TV start up, one will be able

      a) to move some software to the external memory devices like SDcards or hard disks, freeing the system memory for better performance;
      b) to release the restrictions so that some restricted Apps can be installed;
      c) to have freedom to modify the ROM allowing the TV to perform as you like them to perform .

      What are the Main Disadvantage of Rooting? 

      a) There is always a risk that that rooting might go wrong, making the TV unusable; 
      b) Even after successful rooting, there is no guarantee that  TV might not be able to run the way you wanted them to run;  
      c) There is no software support for the operating system after rooting;
      d) There was report that 90% of  Xiaomi TVs failed to work properly after the TV was upgraded with to the latest OS released by the Xiaomi and there were no recourse to restore the OS unless one has a copy of the original factory firmware to "unroot" the TV;   

      To Root or Not to Root? 


      In the early stage before 2016, Xiaomi TVs cannot play Youtube Videos and also run Google Chrome.  Then,  there was an urge for users, particularly, those resided overseas, wanting to root their TVs.  However, Google has now made Youtube and Google Chrome playable on Xiaomi TVs, thus  this urge to root the TV has died down. Very likely that users will have a hard time finding suitable rooting software that could work well in the new models.

       In view of the above, it is advisable not to root the Xiaomi TV but to wait until the manufacturer can improve its operating system if the TV cannot meet the user’s requirement.

       Working Around


      Remember that if there is a restriction,  there is always a possibility that someone, somewhere will find a workaround and share with the communities on how to overcome the restriction. The worse come to the worse, one can always install an external TV box and uses HDMI input to overcome these restrictions. Although this method is crude, it is one easy way to solve the problem than to root the TV.

      Buying Prepaid SIM Cards in Malaysia. Avoid the Cheats.



       2 February 2018


      Introduction


      “I bought a Prepaid SIM card from Maxis in Nu Sentral, Kuala Lumpur (KL). The counter staff helped to register the SIM card and recommended a RM$10 top up for my stay in KL. After a day of usage,  the system reminded me for another top up.  I was shocked to find the top up was never done.”   This is a very common complaint when buying prepaid SIM cards in Malaysia.  
      This article will show how one can avoid this predicament.   


      The Malaysian SIM cards


      1. There are basically 4 different brands of prepaid SIM cards  in Malaysia;   namely,  Celcom,  Maxis,  Digi and U Mobil.  

      2.  The market is quite competitive offering various  kinds of services and schemes with gimmicks to attract the tourists and local users.   Some are offering unlimited and free use of Whatsapps and Facebook etc.  There is even one that offers free traveller’s SIM card but they will recover the cost when one starts using the card.  Here is one good blog that describes the various types of cards 



      The Basics


      Prepaid SIM cards are available everywhere in Malaysia and the prices are mostly fixed.  Buying at the Airport is just a convenient. 

      1. SIM cards would most likely come with some stored value;  some stated upfront the actual value and some hidden the information for some good reasons.  For example,  if one buys a Maxis Card for RM$10, it would have a stored value of RM$5 for 1.5 GB of internet usage which can last for about  a week for an average user;

      2. All SIM cards will need to be registered before it can be used. The process would only take less than 5 minutes;

      3. If one must top up the card for some reasons and gets the counter staff to do on behalf ,  it would better to tell the staff upfront that you will want a receipt and a check for the  added value stored in your SIM card;

      The Cheaters and Scammers


      As tourists,  we are always the easy preys of the cheaters and the scammers.   Unfortunately,  most bloggers are blogging about  how to choose the best SIM card and not how to prevent the cheaters and scammers.   

      In the past,  the cheaters and scammers would normally lurk tourists to buy the “cheapest SIM card available in Malaysia” which sometimes may cost as high as 3 times the price of the next shop.   Nowadays,  this loop hole has been plugged by the Service Providers who stated upfront the cost of each  package on each prepaid SIM card.

      The cheaters and scammers  now started a new scam as there is a requirement for all SIM cards to be registered and most tourists are not familiar  with the complexity;  often,  they will let the counter staff handle the registration.  2 types of cheats and scams become possible:

      1.  Selling of the Personal Information


      The counter staff who handle the registration can  collect and sell the personal information. Fortunately,  the registration is done in front of you so that you can make sure they do not take photos or Photostat your passports or ID cards for unknown reasons.



      2. Topping of Stored Value


      This is one of the most common stunts as most tourists do not want to be bothered about topping the stored value and would leave it to the counter staff to top up the cards for them.   Many would leave the shop immediately without checking the value stored in the card.   Some would keep wondering why they used up the internet GB so quickly in Malaysia.   This is all because the counter staff did not top up the card.

      Most SIM card sold in the market have some stored value enough for the numbers of days as per advertisement shown by the Maxis prepaid card for example.   There is usually no need to top up the card unless you are a very heavy user.  

       Their websites would often contain enough information including how much is the stored value when you purchase the prepaid card.  In the case of Maxis,  the information is hidden in this FAQs



      3.  Selling the Wrong Package


      The Service Providers change their offers regularly to attact customers;  some has 1-day validity,  some 2-day and some  7-day.   They came in with different prices.  The seller might cheat by giving you the cheaper package.   It is good to be familiar with the various packages offered by the Service Providers.  Most of their information are available in their webpages and also in their phone Apps where one can download free for viewing.

      How to check the stored value?


      Most Service providers will have phone apps where one can easily check the stored value or balanced value in the card;  for example,  Maxis has this in the front page of its phone apps


       
      For those who don’t use their phone apps,  they can always key-in some special key-codes to check the balance.


      How to Top Up the Cards?


      This can also be done easily through their phone apps;  for example,  Maxis has the following page in their phone apps to top up the card using credit or Debit cards.   The SIM  cards could also be topped up in specified payment machines and even at convenient stores such as 7-11s. 


      One could also top up the SIM cards using 3rd party service portal such as Recharge,  who will accept many form of payment including PayPal where one's particular information can be kept confidential.

       Complaints if any


      Most Service Providers have a twitter page where one can complain to them about the services they are rendering.   In the case of Maxis,  the twitter manager will respond very quickly to answer your complaints within the day.  They may request for your Name and the telephone number registered in Malaysia and also the location of the shop you purchase the prepaid card.

      DBS Right Issues & Smart Money

      Introduction
      DBS halted trading on 22 December 2008 to announce that it would offer rights issue at a one-for-two ratio. This right issues can be traded in the open market in the SGX between 6 Jan to 14 Jan 2009 and must be converted to ordinary share by paying $ 5.42 per right issue before 20 Jan 2008.

      A day before the announcement, i.e. 21 December 2008, DBS closed @ 8.37 per share; but when the trading halt was lifted on 22 December, the share price opened at a low of $ 7.74 and closed @ 8.05 per share. Thereafter, the share was traded up to a high of $ 9.56 on 6 Jan 2009 and subsequently to a high of another new high of $ 10.38 before it was dumped to a low of $ 8.40 last Friday on rumours that DBS has "breached" a loan contract in Middle East amounting to $ 3.0 bln.


      What's the Actual Price?

      To work out the actual price of DBS's share, one must gastimate the trading price of the DBS's share after 2nd February, when the right issue is converted to oridinary share in SGX. If one were to assume that one DBS share would worth $ 10/= after 2nd February, then today's price must be

      =(2x10+5.42)/3 or around $ 8.47/= . Note that DBS's price has been pushed up to a high of $ 10.38 or someone was of the view that DBS should be traded around $ 13/=, which appeared to be on the higher side.


      What had happened?

      Smart Money could be at play here. One theory is that they have pumped up the price of mother share to sell their rights at higher price and thereafter, dumped the mother share so that they can accumulate again at a lower price.


      How Do We Know?

      Smart Money are being played by Big Boys who know how to manipulate the market and to spread rumours for gains. Jim Cramer admitted that he practiced it although it was quite legal to do so. TradeGuider tracked what happened and showed how one can avoid being sucked into such manipulation and gain from it.


      Transaction Volume

      TradeGuider believes that one can track and follow Smart Money and know where the Smart Money will flow and make money from it. He pointed out the tracking the volume of transaction and the high and low price will tell tales.


      Accumulation/Distribution Indicator

      The Accumulation/Distribution Indicator (AD), developed by Marc Chaikin did exactly what TraderGuide has said. He used the following simple formula:


      ( ( (C - L) - (H - C) ) / (H - L) )* V


      Where C =Close price

      L= Low price

      H= High price

      V=Volume of transaction


      The signals for the AD are quite simple:


      Bullish: when there is a positive divergence or when AD moves higher while the stock is declining.

      Bearish: when there is a negative divergence or when the AD moves lower while the stock is rising.


      Tracking Smart Money in DBS Counter





      ng together. However, the stock finally caught up with the Accumulation/Distribution Line when it broke resistance in November.
      Another means of using the Accumulation/Distribution Line is to confirm the strength or sustainability behind an advance. In a healthy advance, the Accumulation/Distribution Line should keep up or, at the very least, move in an uptrend. If the stock is moving up at a rapid clip, but the Accumulation/Distribution Line has trouble making higher highs or trades sideways, it should serve as an indication that buying pressure is relatively weak.

      Wal-Mart Stores (WMT) began a sharp advance in August that was accompanied by an equally strong move in the Accumulation/Distribution Line. In fact, the Accumulation/Distribution Line was stronger than the stock in early September. After a bit of a consolidation, both again started higher and recorded new reaction highs in early October. Volume flows were behind this advance from the very beginning and continued throughout. The stock ended up advancing from 40 to 60 in about 3 months. Interestingly, as of this writing (December 1999) the Accumulation/Distribution Line has started to move sideways and is indicating that buying pressure is beginning to wane.
      Bearish Signals
      The same principles that apply to positive divergences apply to negative divergences. The key issue is to identify the main trend in the Accumulation/Distribution Line and compare it to the underlying security. Young negative divergences, or those that are relatively flat, should be looked upon with a healthy dose of skepticism.
      The Wal-Mart chart shows a relatively flat negative divergence that is just over a month old. This negative divergence has yet to make a lower low, and should probably be given a little more time to mature. The relative weakness in the Accumulation/Distribution Line should serve as a sign that buying pressure is diminishing while the stock remains at lofty



      If the stock closes on the high, the top of the range, then the value would be plus one.
      If the stock closes above the midpoint of the high-low range, but below the high, then the value would be between zero and one.
      If the stock closes exactly halfway between the high and the low, then the value would be zero.
      If the stock closes below the midpoint of the high-low range, but above the low, then the value would be negative.
      If the stock closes on the low, the absolute bottom of the range, then the value would be minus one.
      The CLV is then multiplied by the corresponding period's volume, and the cumulative total forms the Accumulation/Distribution Line.




      share can be traded between 6 Jan and 14 Jan 2009 in the open market at the SGX.

      . Basically this system caters for 3 types of people:a. Those who are already shareholders at XR and do not want to pay for the rights. The thing goes like this, whether you want it or not, you'll be given the nil paid rights. If you want to subscribe to it, you can do so by accepting it and paying for it before 20th Jan 2009 (last date for acceptance). You can even subscribe to excess rights beyond what is entitled to you too, but it might not be successful. For those who do not want the nil-paid rights (i.e. do not want to accept the rights shares and pay for it), you can sell it in the open market. The last date of trading for the nil paid rights is 14th Jan, 2009. Which brings us to the next category...b. For those shareholders who want to make sure they can get excess rights shares without bidding for it (and thus subjecting to chance), they can also buy the nil paid rights direct from the open market. Of course, if you subscribe to excess rights and bid for a chance to get it, you'll only pay $5.42 for each right. But if you buy from the open market, you have to pay the market price of the right PLUS a fixed $5.42. Might not be so cheap.c. Those who are not DBS shareholders at XR but want to buy the nil paid rights at open market. Basically these arbitrageurs will look for opportunities to buy the rights cheaply, waiting for the nil-paid rights to become ordinary shares on 2nd Feb 2009, then profit (or lose) the difference.However, do not be mistaken that the nil paid rights will be trading at the rights issue price of $5.42. If we take the post-rights price of DBS to be $8.37 (as mentioned in the announcement), then the nil paid rights should be trading at around $2.95 range (8.37 - 5.42 = 2.95). DO NOT assume that it's cheap - it might not be!For example, if we buy the nil paid rights off the market at $2.90 per share (this varies according to market forces), then pay another $5.42 per share (this is fixed) to convert it to ordinary shares, our cost of each new share of DBS will be $8.32. There's no brokerage involved so that is truly our cost. If after the new shares commence trading on 2nd Feb 2009 at a price of $8.37, we basically earn $0.05 per share (8.37 - 8.32 = 0.05) excluding brokerage involved in selling. To succeed in this arbritrage opportunity, we have to guesstimate the price of DBS on 2nd Feb, then minus off 5.42. Any price lower than that is a good bargain, pre brokerage charge.3. The theoretical post-rights price of DBS on 2nd Feb 2009If you've been in the market for long, you'll realise that 'by right', the price can be this and that, but 'by left', all is not right. Oh well, in theory, because DBS is offering 1 new shares for every 2 existing shares, they are going to dilute their earnings and dividends by a factor of 2/3, which is quite substantial for those who are shareholders but chose not to subscribe for the rights. This means that if the earnings is say $3 per share pre-rights, the new earnings will be $2 per share post-rights. Dividends yield too, if their dividend yield per annum is say 6%, the new dividend yield will be 4%. Ouch.Anyway, here's how to calculate the new share price of DBS when the rights shares commence trading on 2nd Feb. Today, DBS closed at $9.37, so let's use this price. The formula is:New share price of DBS = (2 x 9.37 + 5.42) / 3If we take DBS's closing price to be 9.85, then using the calculation, we end up with the post rights share price of DBS at 8.37 per share. However, do take note that the actual price will be swayed by more than just mathematical calculations, hence it might not be what is calculated. Be aware of the risk of arbitraging!There's a whole lot more details that I missed out, so for those who wished to find out more, do visit my newbie's FAQ. Alternatively, you can visit the same version in this blog over here.Now I worry about HSBC's possible capital injection through rights too. Will I be able to subscribe to it because I'm a foreign investor?

      High CPU Temperature in AC Ryan 4K UHD Media Player

      28 January 2018

      The Media Play is AC Ryan VEOLO ACR-VE94000 4K UHD Media Player . It is still available in Q0010 for about $99/= but I bought this second hand set for $40/= in Carousel but it has a CPU heating problem running as high as 80 0C. This article outline a method where one could resolve this CPU heating problem in AC Ryan Media Player. 



      What could be the Reason?

      There are many reasons and one of the them must be poor heat dissipation.  When CPU temperature went beyond the set temperature,  it cuts itself off  to protect the CPU.  



      The Construction


      The set has a Quad-Core CPU (Cortex-A17 SoC) with a ARM Mali-T764 GPU, 2GB DDR3 RAM and 16GB Flash memory.  Its maximum operating temperature is around 70 0C.  

      The CPU has a small heat sink no larger than 35x35 mm as shown in the attached.  It has also a metal plate of around 100x40mm attached by 2 screws on the casing.   The metal plate is offsetted slightly from the CPU heat sink,  providing an air gap of about 5mm between the CPU and the metal plate.  The exact reason for this strange set up is unknown.



      What Could Be Wrong?  And the Solution

      The heat sink was found firmly attached to the CPU by thermal glue.   It could only be removed by heating to inspect the condition.    Repacking the CPU with new thermal glue would be the solution;  instead,  a piece of alumimum sheet was inserted in between the 100x40 metal plate and the CPU as shown with 2 purposes

      1.      To provide a direct thermal contact between the CPU and the 100x40 mm metal;

      2.      To apply some pressure to the CPU heat sink hopefully to reduce the gap if any between the CPU and the heat sink

      The modification appeared to be successful as the CPU temperature was reduced from the original 80 0C to around 55 0C after the piece of aluminum sheet was inserted. The casing took sometime to assemble as some force was required to force-fit the alumimum sheet so that it could be “moulded” properly onto the CPU’s heat sink.

       

       Update:  8 Feb 2018 

      Have extended the sheet of aluminum to also cover all the tops of the COU heat sink and added a piece of thermal pad in between the aluminum sheet and the heat sink to further improve the heat transfer.
