[Solved] - Unbrick Lenovo A7700 & Other MTK Based Phones

>> Download Links:
If you have bricked your Lenovo A7700 phone or any other MTK based Android phone then follow the tutorial below to unbrick it.

There are two types of bricked condition:
  • Soft bricked
  • Hard bricked
Soft brick occurs due to certain software errors and should usually be fixed by just performing a factory reset.

Hard brick occurs due to hardware malfunction. Actually, a hard brick device is the real "bricked/dead" and cannot be unbricked. In this case the phone doesn't turn on at all and is equal to a brick, rendering it useless.

Not sure what I should call my bricked phone. No matter what techniques I tried it wouldn't start at all. Applying the fix below worked for me.

Step 1: Open SP Flash tool. If you do not know how to use it and would like to learn, please check the following link: http://bit.ly/2CHMPPR.

 Step 2: As shown in the image above, select 'Format all+Download.'

Step 3:  Press Volume Down button or if Volume Down doesn't work try Volume up and connect your phone to your computer using a USB data cable. Now your Unbricking process should start, as shown in the video below.



N.B: This will result in deletion of your IMEI number(s). But nothing to worry about; later on you can easily set the IMEI number. You can follow this tutorial for resetting your IMEI number.

Install & Use SP Flash Tool in Linux/Ubuntu Systems

 You can also follow the tutorial here: http://bit.ly/2lWjFlj, and I strongly recommend you to follow the steps there. Below, I will point out the main step you have to note, from the above tutorial, for a successful installation, and that step is Step 4 which reads as follows:

"Now we come to the interesting part, which cost me 2 weeks of (futile) research and frustration. Finally I found Sergio Riveros tutorial on mibqyyo. Thanks to him again and again and again for this priceless piece of information.

Quote:
"The 'modemmanager' package integrated by default within Linux Ubuntu 14.04 and later is not compatible with the MTK Flash Tool for Linux."

To put it in different words: The modem manager controls port /dev/ttyACM0 and disables the Flash Tool. So we blacklist it for the two MTK vendor IDs the flash tool uses:
 sudo gedit /etc/udev/rules.d/20-mm-blacklist-mtk.rules  
You insert these two lines:
 ATTRS{idVendor}=="0e8d", ENV{ID_MM_DEVICE_IGNORE}="1"  
 ATTRS{idVendor}=="6000", ENV{ID_MM_DEVICE_IGNORE}="1"  
Save the file, exit and restart udev:
 sudo service udev restart  
Switch your phone on (fastboot mode will suffice) and off again."

[SOLVED] - Flash Lenovo A7700 Stock ROM & Other MTK Phones Using SP Flash Tool

Recently my Lenovo A7700 mobile phone started crashing and giving various problems. Often, it would prompt messages such as "Google Service Framework has stopped working" or "Unfortunately, Google Play services has stopped" and lots of other errors, which eventually would cause the phone to crash. The only solution that would make the mobile functional again was to remove the battery and start the phone.

Then I tried flashing my phone with Stock ROMS & Custom ROMS hoping to resolve my problem. In the process I came across some interesting tools like SP Flash Tool, SN Write Tool etc. The tutorial below explains the working steps to successfully operate the SP flash tool.

Using SP Flash Tool, I have successfully flashed my phone in both Windows and Linux. In this post I will explain how to flash your Lenovo A7700 in Linux/Ubuntu.
