OP6 TWRP failed...

[cooki1977n]

Hello,

OP6 OOS 9.0.9 OTA 34. rooted.

I wanted to upgrade to OOS 10... I see install last magisk and twrp... so...

I wanted to install a new version of blu_spark (zip version) directly since old blu_spark recovery... and when I wanted to restart ... (so i make a big mystake)

I started reading the tutorials this morning around 9:00 am.
It's 3:30pm and I haven't found anything or rather I've found things that don't work. :crying:

Phone is locked in fastboot mode... no issu. no logo, no recovery...

When i want to flash in ADB I have "Failed to load/authenticate boot image: Load Error"

Phone is reconised bye windows on "android bootloader interface"

I see tuto for MSMdowloadtools 4... but my last W10 don't want to boot in test mode

Is the only way to unbrick?

I think, bootloader is corrupt, so it's possible to reinstall the correct bootloader? (version for OOS 9 and not 10...)

fastboot oem device-info

When I try : fastboot flash recovery twrp-3.3.1-x_blu_spark_v9.107_op6.zip

I have:

OKAY [ 0.372s]
writing 'recovery'...

I test:

fastboot flash boot twrp-3.2.1-0-enchilada.img

OK !

Now, I have a black screen with QUALCOMM Crashdump mode

So?

Download the fastboot rom and put your phone in bootloader mode and flash

Hello !

Yes, can you be more detailed? :angel:

ps: phone is on QUALCOMM CrashDump Mode and I can't have nothing else...

I managed to reboot to my old recovery and then to the A partition. :laugh:

I go to OOS 9.0.8

So, It's possible to move to OOS 10 now? without problem?
