P8 Lite turns itself off while booting to TWRP/CWM recovery - P8lite Q&A, Help & Troubleshooting

LATE EDIT: solved, read bottom of this topic for solution
Hi, so I have a P8 Lite and after properly unlocking the bootloader, I flashed TWRP (versions/ports found on XDA for P8 lite).
After using fastboot fastboot flash recovery twrp.img properly, it outputs OK, indicating it successfully flashed.
Now, assuming all went fine, I tried booting into recovery with powerbutton and volume up, after a few seconds only it turned off, the whole device just shuts itself down.
I then noticed it'd go into Huawei eRecovery when you keep holding it, so I just briefly pressed both keys until it started up, immediately released, and it still failed to boot into recovery.
To make sure I made no mistakes with triggering the recovery boot, I used adb to perform ''adb reboot recovery'' and so it attempted to boot into it, resulting yet again in the same black screen shortly after the Huawei (powered by android) logo, where that black screen is actually the device shutting itself down.
So the conclusion I draw is that the recovery is broken after installing it, the question is how. I'm not a novice to this kind of stuff, as you might have noticed, but still I cannot think of what went wrong, as my bootloader is successfully unlocked through the EMUI method, and I made proper use of fastboot to flash recovery, after which it tells me it succeeded, using the proper recovery for this device.
To double check I also installed the CWM recovery released for the P8 Lite (https://forum.xda-developers.com/p8...overy-clockwork-mod-recovery-cm-12-1-t3342209), as TWRP's for it (multiple versions/releases..) failed thus far, and also with CWM the same happens.
I really want to proceed flashing recovery to then root the phone and install a custom ROM, so any help or ideas what the cause might be, will be appreciated, or anyone that encountered the same problem!
SOLVED (was too lazy to post on time, i fixed it shortly after posting this).
The problem was that I flashed a bad recovery, basically the ALE-L21 has different TWRP versions advertised in the P8 lite section, i happened to choose a not too good one, it may have even been one that didnt belong to my model (like P8 lite generation year), not sure as the section is co-shared between P8 lite model generations, this mistake is easily made.
If you have this issue, just keep trying additional (TWRP) recoveries, the subsequent 2 versions from different publishers that I tried were working fine and the issue stopped.

Help twrp

I have a Huawei P9 Lite and i have installed twrp and android 7.0 on it. Now I want to install Google assistant, but when i try to boot in twrp recovery (volume down + power b) it shows me the screen where it says ''Installing update'' and then freezes at 5 % so i have to hold my power button to power off the phone.
If I dont try to run in the twrp, phone works just fine.
I apologize for my bad english.
Hi there,
I will move your thread in the correct forum dedicated to Huawei P9 Lite for more relevant answers.
Good luck
Bump..
Just to state that I am in the same boat here; as I am facing the same issue. Here's what happened in my case (using a guide found here at XDA-Developers):
-- unlocked the bootloader
-- booted to bootloader and flashed twrp
-- used adb to reboot to recovery (adb reboot recovery)
-- used twrp recovery to flash nougat update (two zip files, one ~1300mb and second ~680mb)
-- had some errors that were expected, the guide said ignore them and reboot after both zips have been flashed.
-- the flash overall was successful as the phone booted in emui 5 with android nougat. However, there was no virtual keyboard; so decided to do a factory reset
-- rebooted to recovery, but this time, the phone booted to huawei erecovery
-- did a factory reset, but to no avail
-- now, i can't boot into twrp to flash anything else. booting into bootloader and using fastload to flash recovery image is successful, but the phone does not boot to twrp recovery; remain stuck on "your phone is booting up" (or something similar).
My phone is not bricked, as basic telephony, wifi and built-in apps are working fine. But, without a keyboard, its pretty useless for everyday use. Any help in this matter will be appreciated.

This seems helpful; but how can I flash recovery if I can't boot to fastboot?
[Update] Oh, got to fastboot, trying the suggested recovery now.
Fixed
Fixed using the suggestion above. Thanks.

Huawei P9 Lite Brick I Need Help

Hi guys,
Yesterday, I unlocked my Huawei P9 Lite with the given code from EMUI, then I installed TWRP (twrp-3.1.1-0-venus.img) and installed SuperSU. All went okay, i managed to delete useless system app, but I realized i did not pass Safetynet Check anymore (and since i'm a PoGo fan..), so I uninstalled SuperSU and tried with Magisk, same issue. I uninstalled both, and couldn't get back the clean safetynet check.
There, I tried to install a official ROM for VNS-L31 xxxx361, but I did it wrong and the whole thing crashed. Now i'm left with no OS, phone is bootlooping for ever. The only things I can access if TWRP and Fastboot mode. I tried to flash img from a huawei release, but i get this error that scare everyone i asked about : remote : sparse flash write failure.
I've no idea how to not trash my phone and go grab another one if I ever want to make a phone call again!
Please help!!
Kindly,
Antonin
I had similar problem but I had no recovery just eRecovery and fastboot (which didnt let me flash anything).
Download FULL rom from:
hwmt.ru/oth/HWFF/info/view.php?find_model=VNS
(sorry cant post links)
Make sure u choose right model and location.
Extract the update.app and put it on sdcard in folder named dload, insert that sdcard into the phone.
Boot to erecovery and shut down the phone from there, then turn on the phone with both volume buttons pressed and wait till the rom will be installed.
If you didnt success to boot with vol + and vol -, try to press power wait for vibration and quickly press both volume buttons and hold.

Bootloader locks itself, can't restore via fastboot

Hi,
recently my friend asked me wether I can look at her P8 Lite which wasn't working after beeing left unused for some time. Basically when she got a new phone this P8 was left in box for a few months and after turning it back on the screen included in attachment appeared. https://imgur.com/a/WcvNByN I'm not new when it comes to unlocking bootloaders and all that stuff as I was doing it many times on another devices so I tought it will be easy job. Well, was I wrong... What I tried so far to recover this phone:
1) I obtained all necesary data to get the bootloader unlock code from Huawei. When I want to unlock the bootloader it works but after I reboot the device it goes back to "Locked" state.
2) It does not boot to recovery with buttons combination.
3) It does boot to fastboot but as I said bootloader locks itself down after reboot.
4) I tried to place UPDATE.APP from various firmweares on SD card and update it that way, it takes extremly long but with this metod it boots to some kind of MIUI recovery in which I have 3 options: wipe cache, wipe data/factory reset, rebboot system. Depending on firmweare it allows me to wpie cache or/and wipe data but reboot system always fails taking me back to this rescue mode screen.
5) Finally I tried to flash stock rom by extracting files from UPDATE.APP via fastboot. It flashes everything except recovery and boot which gives me fastboot error: "FAILED (remote: flash write prim vrl failure)". Interestingly I can flash TWRP recovery without error but when i try to access it whit buttons combination it fails and goes to rescue mode.
Device was stock and unrooted before this. I'm kind of out of ideas, I searched a lot of topics without any conlusion on this, if anyone could help me I wolud really appreciate this. However I think there is no hope for this phone maybe someone here would be able to help.

Oh no... You should contact Huawei and don't tell them that you tried to unlock the bootloader. Your phone may have a thing named "Huawei eRecovery". Launch it, it will download and flash stock ROM.

That option works only in China . I guess

I had the same error on my Huawei P8 Lite 2017 but I broke it myself.
The only way I was able to fix it by not taking it to a store was to use DC Phoenix,but it costs 20 euros for a 3 day license.
It was worth it though,since it did first of all lock the bootloader again,and it bootlooped at first but then I went to eRecovery and it installed the latest update and booted up.

Cannot start into recovery ALE-L21, DualSIM

Hej,
I recently got hands on my sister's old phone which had a broken touchscreen - I fixed that hardware issue, but now it seems I messed up the software?
1.) It's a P8 lite (2015, ALE-L21) DualSIM, which ran the latest OTA update (I think 4.0.3 or 4.1.3? EMUI)
2.) I followed this method to unlock the bootloader
(https://forum.xda-developers.com/p8lite/general/alternative-method-unlocking-bootloader-t3799294)
3.) that included a rollback to B170 (Android 5, EMUI 3) and rooting with KingRoot
4.) I planned on flashing TWRP, but the phone did not start into the newly flashed recovery, but into the Huawei eRecovery
5.) So I assume that it reinstalls the original recovery upon reboot, I tried to flash twrp again, but whenever I use the button combo (Volume Up+Power)
--> it does show me the red Huawei logo, but afterwards the phone is "on, but unresponsive",
having a dark screen, but the vibrating motor works whenever I touch the bottom row of the screen (where usually the navigation buttons are)
6.) Then I told myself, if I cannot flash twrp, I'd at least try to at least get the latest firmware (B620) installed again,
but neither the local update option nor using the buttom combo for dload works,
instead it has the same issue as described in 5.), going through the restart sequence with the huawei logo, but then being dark with vibrations
Did anyone have similar issues (see especiall point 5) and can help me out?
It's in a state of kinda working (having a usuable, but old firmware), but the restarting seems to wrong and everything that needs a restart (going into recovery, installing local dload update) seems to be messed up
I got it working somehow,
the twrp recovery I used might have been bad, so instead I used the one in the LineageOS14 thread.
When I tried to dload with the *#*#2846579#*#* sign combination, it finally started int TWRP
Flashed latest firmware, did backup (just to be safe this time...)
and now am using AOSPA without the issues described in 5.)

Can flash ROMs but can't boot them

I have a Huawei P10 Lite WAS-LX1. I had its bootloader unlocked in a phone repair shop (by shorting testpoint).
Now it always greets me with the message "Your device has been unlocked and can't be trusted".
I can load the boot into the bootloader and I can flash TWRP (I tried 3.4.0 and 3.3.1 from DarkJoker360 and also the one from Pretoriano80).
I am also able to flash system images, for example LineageOS from DarkJoker360.
At first that seemed to work to some extent: the new system kept crashing but at least it was booting.
I tried again and again and at some point I wiped everything but the sdcard using TWRP (that is, including the vendor partition). I suspect that's what I did wrong, because presently I can no longer boot into the ROM I am flashing. Instead, the phone waits for a few seconds, then vibrates once and restarts. The second time, it boots into "Huawei eRecovery" (where I can "Download latest version and recovery", "Wipe data/factory reset", "Reboot" or "Shutdown"). I am afraid of attempting to go back to the stock ROM as I wouldn't want the bootloader to become locked again.
Since I can still boot into both the bootloader and the recovery, I have hope I can recover. But I don't know how.
Does anyone understand what happened (and could explain)?
Also, does anyone know how I could boot into the ROM again?
Never mind. I went back to stock. Also, the bootloader became locked again during the process, so I will not try again.
