P20 Pro won't boot - Huawei P20 Pro Questions & Answers

I was using the FLASH tool to update my phone to the latest version 9.1.0.327 but something mustve happened because the install failed. After that, I tried to fix it but upon rebooting the device wouldn't boot and would go to erecovery. However, it's unable to stay in the erecovery for more than approx 30 seconds so I can't recover my phone through erecovery.
I tried manually flashing the firmware files through fastboot but that doesn't do anything either - it's the same situation and the phone won't boot.
Anyone got ideas on what to do to fix my phone?

exactly the same issue (9.1.0.326 update)
it wont stay in eRecovery either. its bricked for now
UPDATE - All i can manage to do for now is - booot into fast boot, (usb plugged in hold DOWN + POWER)
then flash twrp
Fastboot flash recovery_ramdisk "D:\Apps\Android\P20Pro\TWRP-3.2.1-Pretoriano80-P20P.img"
reboot, now
power on holdin DOWN VoL with the cable plugged in, TWRP. If that doesnt work enter eRecovery, factory reset! Reboot, TWRP comes up automatically
Now i have TWRP back at least. dont know what to do from there

anyone of you can send me boot.img of the 9.1 version please i need it
thanks a lot

Help - ran into trouble with my P7-L10

Hello,
After 1.5 years on B136 I've decided to move to a Lollipop rom. I've wiped my device, flashed stock recovery from B609 and wanted to force-update from sd card .... and device didn't boot into recovery at all.
So far the only recovery that works for me is TWRP, but I can't flash stock roms with it. When I flash (with fastboot) a stock recovery (doesn't matter which, I;ve tried B133Sp01, B136, B609, B852), my device goes into bootloop or just reboots while in the recovery.
I need to rescue my phone now.
Any ideas... ?
This is as far as I get:
Extracted cust / boot / recovery and system from B136 and flashed them with fastboot.
Device reboots, shows Huawei logo, plays animation and sound. After a while - it reboots and goes into recovery.
Recovery is in chinese.
Device stays in recovery for a few seconds then reboots itself.
And on and on....
Does anyone have any clue why this device keeps rebooting itself all the time?
Update:
Since TWRP was working for me, I've tried couple custom roms. Results:
TWRP + material one test rom: flashed fine, got boot screen, got boot animation.... device reboots. After second reboot goes into recovery.
TWRP + B609 test port: same as above.
What can it be that makes my device reboot over and over again, even when in recovery?
I'm out of ideas. Please help.
Thanks.
@GawDroid, try my method,
Download B852 official ROM and copy it to root of your SD card to a new folder "dload"
It should look like this "/dload/UPDATE.APP"
Extract UPDATE.APP (on your computer) using Huawei Update Extractor (all files)
Go into bootloader (Power + Vol Down)
Now open command line and use ADB (Android Debugging Bridge) to send following commands to your phone:
fastboot flash recovery RECOVERY.IMG
fastboot flash boot BOOT.IMG
Now force update by turning off your phone, and turing him back on while holding all 3 buttons pressed down.
When screen comes on release the Power button but keep holding both Volume rockers pressed down until you see an EMUI logo.
If for any reason it fails to install, go back into recovery and do Wipe data/Factory Reset, and than try again.
Let us know how it went
Okay, I did exactly this today:
Extracted boot and recovery from B852 update.app
Flashed both with fastboot
Put dload/update.app on sd card
Started phone in force update mode (vol +, vol -, power)
Phone shows "Huawei Ascend" logo for 30 seconds and shuts down.
I cannot enter recovery either. Phone does the same as above (huawei screen, shutdown).
I have never had an EMUI 3 rom installed before, maybe that's why this recovery can't start? Just guessing...

Flash the boot.img first and then the update

This is how I did it. First boot.img, then recovery.img, then tried to update.
Up. Any ideas why it keeps rebooting regardless of ROM, or even in recovery?

Send it to service
If you haven't unlocked the bootloader/installed TWRP/Rooted, then yes I'd agree with the above comment and send to service.
Otherwise follow the instructions here.... https://forum.xda-developers.com/p10/help/tutorial-recovering-p10-p10-brick-t3600211

I'd asked the service center but they said will wipe my data, is there anyway to retrieve the data back?
Just for understanding: Did you unlock your Bootloader?

i can't access recovery mode, the phone keeps boot looping until the battery is drained, i tried to access recovery mode with the boutons combination to do a factory reset but i can't access it, it doesn't work, the phone stays stuck in the boot loop, i actually don't know how to install the firmware i didn't find it.
once the phone has some power it starts booting and rebooting until the battery is drained, when i plug it it starts booting and rebooting on it's own.

eRecovery is different from Recovery (I wrote above the phone to be connected to charger while booting with Vol+ kept pressing; in Recovery there is no option for Installing the latest - but the option is present in eRecovery), but anyway, you probably cannot boot to eRecovery either ;(
It could be also possible to reinstall firmware from HiSuite but you could not connect if you cannot boot
For flashing from Fastboot, you must have Bootloader and FRP unlocked (but to unlock, you must first boot to the system)- if I understood correctly, you didn't play with Bootloader, Fastboot, flashing, etc yet, hence your FRP and BL are locked
Uhm can anyone help me? pls. I unlocked my bootloader and flashed open kirin AEX P1 Beta and it caused me bootloop maybe because I fail to factory reset the second time or at least can I reflash the custom rom to make it work again but I can't access my p10 on fastboot

Probable brick, need help!

Hi,
I was trying to install Linage OS 14 on my H9L and I got it installed fine. I then tried flashing TWRP with `fastboot flash recovery_ramdisk twrp.img` I then did `fastboot reboot` and once back into Linage I rebooted into TWRP from the power menu. After this TWRP got stuck on the loading screen so I tried rebooting, the phone rebooted back into TWRP and got stuck again. I then tried getting into fastboot by plugging in the USB and holding the volume down, rebooted into TWRP still. I then managed to get out by holding the power button and the + and - volume buttons to get into eRecovery. I then tried to do reset by doing 'Install latest version over WiFi' which downloads then fails and now I can't boot up my phone and it just goes straight to eRecovery every time I boot it up. I can still get into fastboot and I've tried flashing recovery_ramdisk, ramdisk from both a system update zip and from a TWRP backup with also no luck. At this point I really just want to get back to stock.
If anyone can help I'd really really appreciate it and be forever grateful .
Thanks,
Jake

I also cannot flash TWRP anymore.
Power down phone, then plug a USB cable into PC then phone. Whilst plug Cale into phone press and hold volume up.
This should place you into Fastboot mode.
What does it say for FRP.
If it says that is locked that would be your issue of why you can not flash anything.

A small typo above from @hacktrix2006 , Vol Up will actually bring you to eRecovery.
Vol Down will bring you to fastboot mode.
@Sparkrite , nice catch that is what i ment. When i replied i was awake for at total of 1 minute so brain wasn't fully working right.

G973F Stuck on Boot Screen After Failed BeyondROM Install and TWRP 3.4.0-3 Flash

I believe i've royally screwed up and i want to know if there's anything I can do to save my phone.
I downloaded the latest BeyondROM from here after being on a previous version for about a year (not sure which one I was on):
https://forum.xda-developers.com/ga...evelopment-exynos/rom-beyondrom-v6-0-t4017921
I flashed the zip file through TWRP and only after flashing did I realize that I was on TWRP 3.3.1-11 and not 3.4.0-3, which I'm guessing is why my phone is now stuck on the boot logo when I boot it. I went back into TWRP and cleared the Dalvik & standard cache again after this but no dice.
But it gets worse. I then tried to upgrade to 3.4.0-3 by flashing it from TWRP 3.3.1-11 using the recovery partition, hoping to reflash the firmware after doing so.
After doing this and my phone rebooting, not only am I stuck on the boot screen, but now I can no longer enter recovery mode either by holding Bixby + Vol Up + Power. My phone isn't recognized by my PC or Odin now either.
Is my phone completely bricked, or is there a way to salvage this mess i've made?
Could really use some help.
Thanks guys.
If you can go to download mode, try re-flashing the stock Samsung firmware via Odin.

Thanks for the suggestion, however that's my primary issue. I can't get to download mode (which really should be recovery mode since I have TWRP).
Do you think it could be an issue with me rebooting to recovery mode after upgrading TWRP using TWRP itself? Maybe my phone needs to be hard powered off once to access TWRP again?
And since I have that failed ROM install, the only way to power off the phone would be to wait for the battery to drain.
Power+volume down+Brixby goes right into download mode bypassing the recovery

My phone just keeps restarting when Power + vol down are held. Looks like draining the battery didn't help either. I'm stuck on the boot screen even when plugged in with 0% battery. When I remove the USB Cable and hold Vol down + Power, the phone seems to turn off because there's no battery, but immediately after plugging in a power cable, the phone automatically turns on by itself again.
You can try this, but best not to flash anything without charging battery first. You can charge while phone is off:

Unable to enter Recovery mode after reboot from twrp or stock recovery.

Moin,
My phone was one day suddenly unable to boot into system nor Recovery, but could still enter fastboot.
Took me a while to figure out that USB Hubs let flash attempts fail too. (you can watch the drama in my older posts)
Now i was able to flash System back into a workable state and it looks like that recovery is also successful flashed.
BUT...i can enter recovery only ONCE per Vol - and Power on Button.
i have NO OTHER WAY to enter Recovery at all. i have no reboot option in system (LOS 18.1).
In fastboot/adb command and after one succsesfull reboot per keys, it always stuck after the Sony logo into a black screen. i then have to restart it into system with Vol+ and Power (one vibration) or shut down with vol+ and power for 6 seconds (three vibration) to get it either into fastboot (Vol+ and USB connect) or system again. then i have to flash it again to get into TWRP once. i tryed the latest twrp version (3.7.0) and one older version (3.3.1) that had once worked until the phone broke.
Any idea what is going wrong here. i have already try to completly wipe everything from the phone and try to fix SEL Linux in twrp. nothing seems to work. Did i miss something?
/€: Now it is again in the full broken state. recovery nor System won't boot anymore and end in a black screen.
/€²: Found the Problem: my lilca zip was polluted with altered files i forgot about.
