Unbrick Unlocked Huawei P10 - SOLVED

I messed around with my phone (Huawei P10 VTR-L29) and unfortunately bricked it. what happened ------------- To give you the whole story, I tried to root it, but during the root process I found out that the device is encrypted so I had to "rollback". That worked fine and my phone was working ok with one issue - I wasn't able to update firmware via regular system updates. I saw the update, but wasn't able to download and install - it always ended up with some error. That made me decide to reinstall the firmware from scratch. I followed general steps but yeah, I messed up. current status -------------- The only thing I can see now is When I click on download latest version and recovery But after a while it fails: And I am stuck :( I can't get any further .. I tried to connect via ADB (but since I cannot get in the phone to enable USB Debugging (which might be the problem) I am unable to connect (nor ADB neither FASTBOOT can see the device). I tried to create this file: /etc/udev/rules.d/51-android.rules But when I run sudo adb kill-server sudo adb start-server adb devices It's still empty ... I can't even get to the "FACTORY RESET" by pressing and holding POWER + VOL:DOWN for some time; it always brings me back to the Huawei eRecovery Do you guys have any idea how to fix this?
Or is that phone dead for good? I don't care about the data inside.. I would only love to make it work again EDIT ==== with the help of alecxs I made it to the fastboot&rescue mode however this sudo fastboot boot [img] ends up with downloading 'boot.img'... OKAY [ 1.052s] booting... FAILED (remote: Command not allowed) finished. total time: 1.056s similar for sudo fastboot flash recovery [img] ends up with target reported max download size of 471859200 bytes sending 'recovery' (32040 KB)... OKAY [ 0.995s] writing 'recovery'... FAILED (remote: Command not allowed) finished. total time: 1.001s EDIT2: ------ I asked as well one of my friends and we moved on a bit more ... I tried to unlock the bootloader sudo fastboot oem unlock [unlock_code] Then I got this screen: I went with the option (2) and that brought me to the first screen mentioned in this article "Huawei eRecovery" but when I repeated the VOL:DOWN + USB:CABLE:PLUG trick :) I got this I tried a different TWRP (for P10 specifically) from this link: XDA Devs - P10 TWRP Flashing worked fine: sudo fastboot flash recovery_ramdisk twrp_p10_0.1.img I got: target reported max download size of 471859200 bytes sending 'recovery_ramdisk' (24954 KB)... OKAY [ 0.771s] writing 'recovery_ramdisk'... OKAY [ 0.232s] finished. total time: 1.003s after sudo fastboot reboot right after this command, I need to unplug the USB cable and hold VOLUME:UP to be able to get to TWRP (swipe.d to allow modifications) ... am there already now I am looking for any ROM for my P10 to flash it. I want to try this one: TheUpgradeGuide.com - Pixel Experience I downloaded the gApps and ROM ... uploaded it to the "Internal Storage" of the phone (there was a folder TWRP so I put it next to it) . .. /TWRP rom.7z gapps.zip Went on wiping -> WIPE -> ADVANCED -> checked these - Dalvik Cache - System - Cache - Data swiped to wipe (uplugged USB) .. but got this error: Updating partition details ...

working at all and I am landing on this screen instead :( EDIT 4: ------- output of fastboot getvar all is here: getvar:all FAILED (remote: Command not allowed) EDIT 5: ------- see the output of the

EDIT: ok, following this manual xda-developers - Jannomag I was able to upgrade to 8.0 (with a little hiccup - just had to manually restart it multiple times) and then to 9.0 (no problem at all this time) and right after 9.0 it offered me (via system update) automatically the newest 9.1.0.263
