SOLVED: HardBrick (between versions 7.0 and 7.1) | Fingerprint | Secure way to update

SOLVED: HardBrick (between versions 7.0 and 7.1) | Fingerprint | Secure way to update to any Android version, including 8.0

First of all I’d like to thank all the people here in this post and inside the xda community, because without your knowledge and experiences I would never understand my problems and find the solutions.

Actually, my solution is a mix of your solutions. But, before we talk about it lets understand what has happened with me last night.

1-	My Moto Z xt1650 – 03 was already with its bootloader unblocked, with TWRP installed, and in the 7.1. android version

2-	I receive the notification of Android 8.0

3-	I decided to repass the 7.0 firmware (I thought that it was the only rom available, because all the others updates was just simple updates but not a completed firmware (in my mind kk) )

4-	Conclusion: I got my phone Hard bricked. It only showed a black screen and I started to looking for a blanc flash to solved it)

5-	After 3 hrs I get my phone on again but with OEM blocked and any rom worked

6-	After + 2hs I resolved it and I started to try to discover how I could return to my 7.1 version (it took me +2 hrs +1h to solve the fingerprint problem)

So, now It’s the solution time:

1)	To solve the hard brick: You have to use the correct blank flash according with your bootloader version (my lucky was the version 91.08 that I found here thanks to Angourakis LINK: https://xdaforums.com/moto-z/how-to/guide-how-to-unbrick-moto-z-hardbricked-t3590133/page9)

a.	Patience is necessary because it really take your time to make it works.

b.	The process works fine in Windows 10 x64 in USB 3.0 ports

2)	To solve the Oem Block: You have to flash the correct gpt (Never ever mix up with this file, really). I found the correct one here (LINK: https://xdaforums.com/moto-z/how-to/guide-how-to-unbrick-moto-z-hardbricked-t3590133/page15) as well thanks to Eriton Carlos. After I flashed it my bootloader returned to normal and I was able to flash any rom

3)	To solve the fingerprint: you have to flash via fastboot a firmware of LA as described here thanks to charlylennon: LINK:https://xdaforums.com/moto-z/how-to/guide-how-to-unbrick-moto-z-hardbricked-t3590133/page15

4)	To solve the flashing of the correct rom that allow you to update until 7.1 and then 8.0: I flashed a 7.0 US version via Fastboot and then I flashed via ADB & original recovery a update of 7.1 yet thanks to Jessooca (LINK:https://xdaforums.com/moto-z/how-to/how-to-update-to-official-7-1-1-moto-z-t3640298 )

a.	When it worked, I try to find the others OTA updates to flash in the same way but I couldn’t find.

b.	So, I extract them one by one using a getting OTA link process that I found in youtube thanks to a colleague in the facebook moto z forum (DJ Thiago Mello)

c.	I tried my lucky updating one OTA update by one via ADB & Recovery and now I’m back to 7.1 december update ready to update to 8.0

d.	The battery performance has increased in this process (the battery is new as well)

e.	While I’m writing this I’m downloading the 8.0 OTA version to try to flash via recovery, and if it works we can maybe use the same process in the future for the next updates : Get the OTA link, download it, flash it, enjoy it

f.	iT REALLY WORKED!!! I’m in 8.0!!!! LINK photos: 1: [IMG="Print 1"]https://mega.nz/#!RhwjVQJS[/IMG] ; 2: [IMG="Print 2"]https://mega.nz/#!I8px2ZiY[/IMG]
