No Reboot After TWRP Flash

Hello, i had a lot of troubles with battery drains recently, by curiosity i wanted to restore my stock backup.
So i did and the phone was stuck during rom boot.
So i wanted to go back to TWRP to fix things but instead it went back to stock recovery.
Okay, so i wanted to flash TWRP again but after flashing the recovery.img,
nothing happens when i enter fastboot reboot
I forced shutdown and re tried many times with other twrp files, always the same issue i cannot reboot with the flashed recovery ! ! !
please HELP :angel:

To boot to recovery, shut down the phone, press volume up + power button, when the phone vibrate release the buttons and it will boot to recovery.
The command "fastboot reboot" will just reboot normally the phone.

sorry but my problem is that i cannot reboot in twrp anymore, it always reboot on STOCK recovery !
dunno what to do i got to meet foreign customers tomorrow without my phone i dunno how i'll do, so unlucky it happened to me today
i even tried flashing on another computer, and trying to restore with stock recovery or huawei app but none are working.
to make it clear, i can just fastboot.
so what should i flash to restore/unbrick my phone ? don't care if i lose data, just need to call tomorrow !
edit: some folks say to put update.app in load folder on sd card then boot with the three buttons but which update.app file should i copy ? i got a VNS-L31 should the SD card be in FAT32 ?

Are you sure you flashed TWRP? Try to download it again and flash it from fastboot mode.

yes sure i did it like 20 times this afternoon, i'm trying to fix it for 5 hours lol
in fact i just was able to boot the restore .app while booting with the three buttons, it's installing updates, hope it will fix all the partitions/recovery/boot/system... and all those necessary stuffs
edit: finally huawei animated boot logo is showing UP !

On which firmware are you and which TWRP did you tried?

i was using meticulous TWRP v3 and some of his builds for several months and i had trouble with those roms.
so i restored my stock backup and everything was not working anymore, each i tried flashing it always went back on stock recovery a every reboot, impossible to flash twrp anymore...
looks like the phone is stuck in a boot loop lol pfffft
edit:
FYI what i just tried is restoring this image http://consumer.huawei.com/lk/support/products/downloads/huawei-p9-lite-lk.htm (the first one ASIA) but the phone is still booting looks like a fail, could it be incompatible ?

I see.
If you managed to restore with the update.app and the 3 buttons, everything should be fine. It will take some time to boot up, so just wait for a while. Also the bootloader probably re-locked so you will need to unlock it again.

it can relock ? i will check !
if it does not work should i fast boot flash system.img, recovery.img, cust.img, cache.img and boot.img ?

I think the best thing to do should be a factory reset from recovery, stock is fine, then reboot and wait for 15-20 minutes. If the update.app succefully installed there should be no problem

Please help, I have singolar bugs in modding

Hi.
I have this phone since two years, and when I started modding I noticed a bunch of bugs that only I have.
For example, TWRP V3,-3.1.1 doesnt't work for me. I can flash it, but when the "swipe to allow modifications" screen displays, if I touch anywhere it reboots in system mode.
I asked before and nobody seems to have my same errors.
The only version that works for me is 3.1.0, but I have a bug whit ROMs.
It flashes ROMs correctly, but when the ROM boots, my phone just turn off and the red/green led of death starts blinking, luckly I managed to recover my phone from that.
My phone is an ALE-L21, i didn't install anything incompatible, so I don't know what I am doing wrong.
Sorry for my bad english

You need to flash required version of emui to install a particular rom. Maybe this is happening because you didn't meet the requirements. For example to flash RR you need to flash B895 before. Then the rom will have no bugs.

So the emui rom b895 booted properly. But when you flash Resurrection Remix your phone got stuck at black screen.
Correct me If I am wrong.
.
Also after you flashed emui which twrp did you flash because when you flash emui it replaces twrp with huawei's recovery.

I flashed with the only twrp that works for me, TWRP 3.1.0, emui booted properly. When I flashed Resurrection Remix, all went good, but when boot animation end my phone just turn off and a red and green led starts blinking

Anyone has my same problem with twrp?

It is very rare but it happens ...
Unlock your the bootloader again! I think you have get some issue in that process.
Try to flash this TWRP: https://forum.xda-developers.com/p8lite/orig-development/twrp-t3609582
boot in bootloader [ with phone off press vol - and plug the usb ], wait a few secs
Copy the TWRP image in to ADB folder and open cmd in that folder, write this code :
Code:
fastboot flash recovery TWRP_3.1.1-0_ALICE.V4.img
Then unplug the usb and press vol+ and power untill reboot and screen turn ON then release the keys.
Tell me if TWRP is working fine...

You should try to flash twrp 3.1.1 after flashing emui (it might work on that version of emui) and then flash RR otherwise do what persona78 said.

Zte axon 7 reboot loop using axon7toolkit

Hello Experts. I am currently having an issue with my Zte axon 7 or ZTEA2017U as the back says. I was using the AXON7TOOL and I used the unlock boot loader feature and it unlocked to boot loader then I choose root and it rooted it but now it does not boot up! It says "Your device software can't be checked for corruption. Please lock the bootloader." "If no key pressed your device will boot in 5 seconds" and it never boots up it shuts down and does it all over again. SOME PLEASE HELP IM PANICANING. IF U NEED ANY MORE INFO TO HELP PLEASE COMMENT! its running Android 7.1.1 Nougat I also tried Factory Reset and Wipe Partiton and that did nothing.

Oh god don't panic. Do NOT lock the bootloader though!
When that screen shows up, hit the volume down button and select 'recovery', then hit power. It should boot up on the recovery. Three things might happen:
a) you will boot into TWRP, in which case the fastest way would be to install Lineage or a Lineage based rom. If this happens download a LOS-based ROM, and also the Universal Bootstack and A2017U modem, then put them on the phone, wipe system, data and cache, and install all 3
b) you will boot into the stock recovery. if this happens you'll need an SD card (4gb or more), you simply put an official A2017U update.zip there (tell me if this is your case and I'll see if i can find a link)
c) your phone will simply reboot, in which case you might need to use MiFlash

When I goto Apply Update from SD card it says "Sorry,you can't sdcard upgrade" im not sure if that normal
I GOT Option B btw and I do have a 4gb sdcard in currently

This is not good. It can't be dm-verity because the toolkit disables it when rooting. It has to be a problem with the new version of SuperSU. I'll downgrade it when I get the chance. Thank you for bringing this to my attention.

2.79 always works, though it'd be best if you just added magisk 14

Ok I was lucky enough it get TWRP on it so what do I do now? I was able to flash it with miflash. I also cleared the entire phone so now it says no os are you sure you want to reboot? So how can i install the Operating system. Sorry for all the hassle this is my 2nd android device i'm used to apple and the easy jailbreaks and restores. Can I have the download links to the things I need to get cause I don't have a clue what to look for. I really shouldn't have done this for being such a noob. XD

@sonic1337 I downgraded the SuperSU version. The root option should work now without issues.

Thanks for downgrading it but my phone no long has an os on it so I cannot us the root anymore I need to know how to reinstall it. If you can help me with that I can try it again.

get DrakenFX's TWRP-flashable stock system zips for the A2017U (be SURE they are for the A2017U).

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.

[Help] Bootloop after updating, usb debugging not enabled.

Using the miflash tool I flashed stock firmware (some version of android 8) after previously having a custom ROM installed. Everything worked fine until I rebooted after updating to the latest version using OTA.
My phone never got past the android one screen where it would freeze part way through, and after removing my sim card I could get to the pin unlock screen before the lock screen but after inputting the correct pin it would reboot and ask me for it again and again. I can get into fastboot fine but since usb debugging wasn't enabled and my bootloader is locked I can't reflash.
Booting into recovery also only brings me to a screen where the android mascot has a red triangle with an exclamation mark and a message saying "No command", so I can't factory reset.
Is there anything I can do to unlock the bootloader in this state or factory reset? (all flash tools and fastbooting into TWRP require the bootloader to be unlocked which in turn requires usb debugging to be activated)
Thanks for your time.

Update: I messed around with stuff on the cli based tissot tool and used option 2 to boot me into TWRP. It didn't do that but brought me into android where a system process kept repeatedly closing until a random factory reset happened.
I then got into normal android for a bit before I had to reboot (did remember to unlock the bootloader this time). I can now install twrp fine but every time I install the stock rom using miflash or try to install resurrection remix through twrp I get the same bootloop issue.
For some reason also my internal storage is completely empty no matter what i do so i need to sideload roms via sd card. And sometimes twrp gives me the error "failed to mount /system"
Trying the latest version of LineageOS next.

Update 2: if you have the same issue I had, the only working fix I've found is this restore point for twrp. Have not tried to update yet in case it breaks again but will make a final update with how that goes.
