In the previous post, I wrote about how you can use the extraced files, and one use is flashing them, which you will learn in this article.
The process itself is quite simple, but risky as well, so please be extra careful, when typing filenames. Do things exactly like I wrote them down in order to minimize the possibility of errors.
Instructions written below will reset your phone to it’s stock settings. The internal memory will be completely wiped, all the installed programs, and setting will be deleted. You should back up your important things before continuing reading this article.
You’ll need these:
- USB cable
- ADB and Fastboot knowledge
- BOOT/CUST/RECOVERY/SYSTEM files
- Approximately 15 minutes
Got everything ready?
Great, let’s get started:
- Turn off your phone.
- Connect it to your PC via the USB cable.
- Hold down Volume Down and Power to boot into Fastboot mode.
- Get your 4 extracted files and copy them to the folder of Minimal ADB & Fastboot. (where you can find the adb.exe and fastboot.exe)
- If the copying is done, open up a command promt.
- Check if your device is connected via the
- If it is, then flash the BOOT.IMG file entering
fastboot flash boot BOOT.IMG
- Next, flash the RECOVERY.IMG by typing:
fastboot flash recovery RECOVERY.IMG
- After that, flash the SYSTEM.IMG with the
fastboot flash system SYSTEM.IMGcommand. *
- Lastly, flash the CUST.IMG by typing
fastboot flash cust CUST.IMG
- If all the flashing is done, restart your phone with the
* – Since the SYSTEM and CUST file are much more larger than the other two, the program will flash them in parts. It may seem like the program is frozen, but it’s chopping up the large files into smaller ones in order to flash them. You can check the Process Manager, and see the HDD usage of this process.
If you’ve done everything right, after booting up, you should see the same thing when you took out your phone from the box for the first time. It’s setup time again.
- Something forcefully ended the flashing process: there are powerbreaks sometimes, yous USB port and USB cable can get broken as well. In this cases, probably, you’ll only need to reflash the file you were trying to flash while the trouble happend.
- You’ve flashed a corrupted file, and the phone doesn’t work: The files probably get corrupted while downloading, so you should try re-downloading, or if it’s possible try downloading another UPDATE.APP, and flash everything again from that.
