DESCRIPTION

I've bricked my phone some time ago and I recall I've had also a few problems flashing . But anyway I was succeeded . In order to do it it must the most important to have the proper QFIL drivers and also the proper QFIL files . So , I have stocked in a PC folder the right tools to revive your phone . No matter is X520 or other . It must be X52x series with Snapdragon .
Obs. – I used FlasOne1.9 . Put FlashOne in C:/
- Put Unbrick.zip to "backup" folder in FlashOne folder
- Boot phone pressing same time Vol+ and Vol- . Connect the phone to PC . If you face to any kind of error , repeat steps to connect .
- Interesting thing I succeeded flashing (was OK) even FlashOne showed some error or it has been blocked somehow .
- After flashing you'll see that ROM is encrypted . That's it . This was the Qfil files I found on the net . This is , I think Indian version . For that you must enter in TWRP , wipe DATA , click on repair file , click on ext4 . That's it all . You're phone is back to life .

In link I provided they are all tools to unbrick . Included QFIL files named "Unbrick"

※Please make a backup of your device before installing or updating ROM
