Beginner’s Guide: Flashing your  China Android Smartphones
 
 Hello all,
 This  is a republishing of a beginner’s guide on flashing, it has   decided to  make this a lot easier to understand because a lot of people   have had  difficulty doing the procedure, also this article contains   update  guides on the process.
 
 
 REMEMBER:  PLEASE USE FIRMWARE INTENDED FOR YOUR  PHONE,  USING FIRMWARE NOT  INDICATED FOR YOUR PHONE COULD CAUSE SERIOUS  DAMAGE  OR MAY POSSIBLY  BRICK YOUR PHONE.
 NOTE: Do at your own risk, and remember the needed precautions when    doing this procedure, and also more importantly “DO AT YOUR OWN RISK”
 
 There are actually 2 steps in flashing your phone into a newer firmware.
 
 

• Card flash
  
• Cable flash

1. Card Flash
 
 
 
 
 

CARD FLASH: Which  means using your SD Card  to install the firmware,  much easier and  least risky, however, you  need to have the recovery  installed.
 
WHAT YOU NEED:
 Micro SD Card, preferably at least 4 GB
 Battery, fully charge or not below 70%
 

 
 
 

STEP BY STEP PROCESS:
 

•  Your ROM (in zip format) send it to your SD card, Remember  not to   unzip, and make sure your SD card is not corrupted (blank is    preferable).

 

•  Turn off your phone, insert SD Card.

 

•   Insert Battery, Enter RECOVERY MODE (Normally done by  pressing Power   Button and Volume – Key Simultaneously) Or you may use  Volume Up (+)   depending on your device. Hold for 8 secs until you go  to Recovery Mode   (Menu System with Dark background)

 

•  When you  enter Recovery Mode, You will see options (see  image below).  Touch  Navigation doesn’t work, instead Volume Up and  Down key and Power   Button for confirmation or enter.

 

•   First you need to wipe data and also data caches before flashing.

 

•  Then choose install zip from SD card and Confirm (power button)

 

•   After that your new ROM will be flashed to your phone,  remember that   if the ZIP is corrupted, security measures “installation  will be   aborted” or if your are trying to flash the wrong ROM.

 

•  Reboot your phone

 NOTE:  if you encountered an error where your SD card   is not recognized or  detected by the phone, please wipe the data or   format your SD card  (blank) send ROM back again to SD card and then   insert on phone.
 

2. Cable Flash
 
 
 

 CABLE FLASH: Is  much more complex and  riskier. When is it  used? For example, a ROM  update from Android 4.0 ICS  to Android 4.1.2  or 4.2 Jellybean. Where  you need to install a  completely new system  from scratch. In this area  Card Flash is  practically useless.
 
 WHAT YOU NEED
  USB Data cable
 Battery, fully charge or not below 70%
 Computer (windows 7, haven’t tested with Windows 8)
 ZIP File (rename it in English)
 
 STEP BY STEP PROCESS:
 

• Install msxm16 or 6575/6577 USB Driver (older) for dual core versions
  
• Install USB Driver, try to connect Phone and PC, see if it is detected  (go to device manager), if not, reinstall and reboot pc.
  
• Extract Flash tool (newest one for MT6589) SP_Flash_Tool_v3.1304.0.119 or later
  
• NOTE:   Flash tool is soooo buggy, sometimes it  works, and other times   doesn’t. If it doesn’t work, you need to install a  newer one or   sometimes a previous version works. Extract ROM on desktop  (you may   place all the files on the desktop to make it easier).
  
• Remove battery from phone, SD Card
• Open Flash tool.exe, click Scatter loading and look for “MT6577_scatter_emmc.txt” all files should be ticked.
• NEWER   ROMS (“Samsung5410_Android_scatter_emmc”),  doesn’t allow you to   continue, please rename to  “MT6589_scatter_emmc.txt” (if you have a   MT6589 phone). it should look  like this   “MT6589_Android_scatter_emmc.txt”
  
• Click firmware Upgrade, Insert Battery (do not start phone) and connect your phone to pc via USB. and leave it be
  
• Wait until the green circle shows (please do not interrupt) firmware update is done and now you
