Revert from Custom to Stock ROM on ALE-L21 - P8lite Q&A, Help & Troubleshooting

Hi there,
I have (hopefully) a small problem going back from Custom ROM back to the Stock Huawei ROM. I didn't do a backup of the Stock, because i thought i can download it somewhere anyway, which probalbly wasn't the smartest thing.
So i downloaded a 6.0 ROM from h++p://consumer.huawei.com/za/support/phones/p8-lite/
I'm not sure, which version i need, so i downloaded the "ALE-L21, Android 6.0, EMUI 4.0, C185B561, Open Market, Southern Africa Cell C, TelKom" version, and tried the "Force upgrade" method which was written in the PDF. It says "Format SD Card", but doesn't mention, to which Filesystem i should format the SD Card to, so i tryed vFAT, followed the furthur instructions, but when i boot up the Phone with Vol Up/Down Pwr Button pressed, it vibrates shortly and stays on the Huawei Boot logo forever or until the Battery is flat.
So i tryed to examined the update.app file, and surely, its some form of archive, so i extracted the recovery.img from it and flashed it, because i thought i may need the stock recovery to get the Vol Up/Down Pwr Button method to work, but the recovery didn't boot with some error, so i reverted back to the TWRP and did get it work/boot again, but i'm now stuck to the custom recovery/ROM, and i don't want to go any further with this fastboot flashing methodes because i'm not entirely sure what i'm doing.
I know, this is probably a stupdid question, and those ALE-L21 Fanboys are laughthing at me (at least i hope so), but i wanted to ask if im missing something obvious or somebody is willing to help me out (which would be really nice).
Thanks in advance

Can't flash any recovery

I've unlocked the bootloader and flashed the Revolution Recovery B9, but I can't mount 'data' , so I modified the partition into F2FS and then formatted it. After that I couldn't enter to system, so I used three buttons to recovery the stock firmware. Now I can't reflash the TWRP and I can't add any goggle account.
What should I do?
Thanks before
What version p9 lite vns- ??
What do you want to install as firmware?
Info. If you wanted to be helped, helped too.
Hi,
have similar issue.
Bought P9Lite, originally on Vodafone UK/IE. VNS-L31C02B120.
Flashed B432 ROM which was OK, although changed to C900. Then I flashed something which was posted as UPDATE.APP. I thought it's an update, but then saw the size, was about 32MB. Since then it boots into Huawei eRecovery, which is uselless as it connect via Wi-Fi but does nothing. I can boot into fastboot/Recovery mode but thats it.
Tried flash Vodafone ROM but it stuck at 5%, no matter what I try to flash. The last when it booted still showed the Vodafone start up logo.
Any help appreciated...
Bootloader locked, no root.
1) Disconnect and power off.
2) Put a stock rom (UPDATE.APP) on SD card in folder dload and put it in the phone. If you have not, create folder "dload"
3) Hold down all 3 hardware buttons for cca. 10 second (Volume+ AND Volume- AND Power) until the phone enters EMUI system update mode and stars update from the SD card.
4) Phone will reboot and you have OS

HELP Soft Bricked A2017U

The issue I am having is that I wanted to set my phone back to factory, after I relocked the bootloader my phone when booting(with or without the volume keys) would shut off right after showing the ZTE boot screen. Now when I connect it, it shows up as HS-USB QDLoader 9008 (COM5)..
Ive been looking at these two forums similar to my problem:
https://forum.xda-developers.com/axon-7/help/bricked-a2017u-t3573798
https://forum.xda-developers.com/axon-7/help/a2017g-totally-bricked-t3537990
I understand I should use the axon7tool(When I try "axon7tool -r boot" i get failed to connect) , but I dont know exactly what I am doing.. I apologize for me being so dumb about this but if someone could please spell out exactly what I would have to do, to get my phone back to factory settings. Any help would be greatly appreciated.
RECAP: Bootloader locked, shows up as HS-USB QDLoader 9008 (COM5), It did have TWRP.
EDIT: When trying MiFlash, I get a ERROR_BAD_FORMAT 0
I just did the exact same thing you did and had the same issue. What worked for me was downloading the factory image from ZTE, putting it on an SD card, going into stock recovery (vol up + power) and select apply update from sd card. The file you download from ZTE is double zipped, so make sure to extract the update.zip file from the parent zip before you put it on the SD card. It will be in a folder with the same parent zip name. I no longer can boot into bootloader from stock recovery (not sure if that's normal), but at least my phone works again. Here's the link.

Hope this helps.
EDIT: I also had TWRP when I locked my bootloader, so I'm assuming you're able to get to stock recovery with volume up + power.
Doesnt let me boot into anything.. Not sure how I screwed it up this badly. Im trying a MiFlash method right now to see if it helps
what happens when you hold down volume up and power button at the same time? you should feel a vibrate and when you let go, you should see the stock recovery.
No, Just shuts off after the ZTE logo pops up
The phone might still be on at that point. When the ZTE logo would pop up for a split second for me, MiFlash was able to see the phone. What happens when you just hold the power button for about 10 seconds right after the screen goes off? Does it stay off?
I believe you are right, when the logo isnt up(after it disappears) that is when it connects as the COM5 otherwise when the logo pops up it disconnects the resumes the cycle.
so if I hold it, it just keeps showing the ZTE logo then shutting off
Just to clarify, holding down both the volume up and power button simultaneously at the same time for at least 3-5 seconds after the phone is off (not after the screen goes blank after the ZTE logo) still gives the same result as if you just pressed the power button?
Yes.
If MiFlash can see the phone, maybe you can unlock the bootloader again?
exact same problem as you, except MiFlash successfully flashes B19 but it still doesn't boot
What you need is FLASH stock recovery in EDL Mode.
That will fix your problem..
P.S. as soon you boot your device after Flashing stock recovery ,will perform a factory reset.

You should download YOUR variant SDCARD UPDATE zip and flash using stock recovery.

I have not tried to flash a redownloaded version of B15 because I cannot move the file onto my sd card. I was able to flash a signed twrp on locked bootloader before to enable MTP, but whenever I flash a signed twrp now, I just get stuck on zte screen. Why is this phone so inconsistent?

I have screwed up my phone, please help me fix it

I have rooted the phone and was using a custom ROM from meticulus.co.vu as well as his custom twrp.
I have the VNS-L31 variant.
I wanted to roll back to stock because the fingerprint sensor didn't work due to me not clearing the saved ones when I changed ROMs.
What I did was factory reset the device, flash stock recovery, cust and boot (from update.app) onto the phone and then put update.app into the SD card in a dload folder. I then proceeded to hold the Vol+, Vol- and Power buttons to update manually. This didn't work because it said 'Software install failed'. Now the phone only boots into eRecovery and fastboot. I cannot get into TWRP despite flashing it multiple times through fastboot.
I am completely out of options, please help me xda.
EDIT: I managed to get it working - for those with a similar issue - download firmware finder and go through ALL of the models, one will work!
However, I cannot sign into google play...
Maybe this helps? http://www.techoxygen.com/bypass-google-account-unlock-frp-huawei-p9-lite-nexus-6p/

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.

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.)
