How to Unbrick and flash Stock ROM on Lenovo K3 Note (k50-t5)

If you are familiar with the rooting process, you probably know that rooting and changing the ROM in android phone remove the manufacturer warranty. But if the phone already have official ROM the warranty will never void.

The official ROM for Lenovo K3 Note smartphone is now available. At below I have given the procedure to install the stock ROM on your phone. By installing this ROM you will back to official ROM.

PRE-REQUISITES:


1. First ensure the battery of your phone is above 75%, so then it will never get switched OFF during the middle of the process.

2. Next take full backup of your phone.

3. Also backup the important data like SMS messages, Whatsapp messages, Contacts etc., as this would be formatted during the process.

4. Next install the drivers for your phone using Lenovo K3 Note drivers.

Disclaimer : Follow the given below procedure at your own risk. I would not be held responsible for any damage that occurs to your phone, in case you do not follow the procedure properly.

Install Driver :


Install the driver then restart your PC, then connect your phone to PC via USB cable and wait till Windows configures it. Make sure the USB Debugging is enabled in this process. Once the configuration has completed, again restart your PC.

If you are using Windows 8 or Windows 8.1 then you may face problem to install the driver so follow these steps to install an unsigned driver.

1. Win + I -> Change the computer settings -> Update and Restore -> Restore -> Restart Now.

2. When you turn off the tap Diagnostics -> Advanced Settings -> Boot Options -> Restart.

2. Extract and open the SP Flash Tools and run "flash_tool.exe" as administrator.

  3. I have succeeded in installing both the Chinese and ROW versions of the rom on my K50-T5. After flashing I turn on the phone and I can hear it bootup. The phone vibrates and responds to touch and buttons but the screen has a gray background with black vertical stripes. The screen was working fine before the first flash. I have tried flashing it multiple times with roms download from different sites and different versions of SP flash tool. Does anyone have any idea whats going on here?

  4. This code (Code: fastboot reboot) will reboot your phone and do not allow it to reboot. Just remove your battery.

    Step 4 - Insert the battery again and put back your back cover.
