Root, Downgrade and install TWRP

For the last week I have been trying to root and install TWRP on my Huawei p8 Lite ALE21. Sofar every attempt has failed.
Steps taken:
Get Bootloader Code
Unlock bootloader with "fastboot oem unlock"
Flash TWRP with "fastboot flash recovery recovery.img"
Result:
When booting into recovery the default "Huawei eRecovery" opens, not TWRP
No app can detect root
Additional info:
TWRP form here: http://forum.xda-developers.com/p8lite/development/testing-twrp-2-8-7-x-huawei-p8lite-qcom-t3187758
Trying to debug the problem, I entered
Code:
fastboot getvar all
this returned
Code:
getvar:all FAILED (remote: Command not allowed)
Additional I have tried to downgrade to android 5.0 again, but after copying the Firmware to the "dload" folder and holding the Volume-Up and Down and Power buttons, the phone wouldn't do anything but show the huawei logo and turn off.
Any help would be very appreciated!
Thank you in advance,
Oisin

"No app can detect root"

The phone reboots, shows the HUAWEI logo and then turn off again.

Sorry, i didn't read the post linked.
You need twrp 3.0.2 for B5xx, i was thinking you had the right one (2.8.7 works on kk and maybe lollipop), so here you are: http://forum.xda-developers.com/p8lite/general/twrp-3-0-0-0-p8-lite-kirin-t3343320

L31- Brick after downgrade Nougat to MM

Hello !
Last week, i get the nougat beta firmware for my P9Lite (L31)
Today, when i want downgrade to MM, my phone was bricked.
I tried all methods i see on the forum but the phone don't start anymore.
Install via fastboot : FAILED
Install via eRecovery with update.zip : FAILED
TWRP NOUGAT B2 flash : FAILED
If you can help me please, thanks in advance !

unlock bootloader.

I have exactely the same problem, i can't do anything, i have the bootloader unlock, i have acces to TWRP nougat, bug the system don't boot ;( Please help !
I have flash system via fastboot, Failed.
I have no phone now

i also experienced that...this is how i resolved it:
1. Sideload the OEMinfo for VNS-L31 dual sim (or whatever version of P9 Lite you have)
2. Unpack the MM update.zip for the appropriate version of P9 Lite you have.
3. Create a folder on your sdcard called "dload'
4. Put the UPDATE.APP from the unpacked zip file into the dload folder.
5. While phone is switched off, put it into download mode by simultaneously pressing volume up + volume down + power button.
6. Should downgrade to MM.
7. All done!!!
Care must be taken as the OEMinfo is very P9 Lite version specific (ie, Dual sim and single sim).

OEMinfo for VNS-L31 can be found here http://www.htcmania.com/showthread.php?t=1261335
Sideload is a function, rather a command used in adb. Sideload is used to directly flash a zip onto your phone...Simply put the zip file into the adb folder. Thereafter enter TWRP, click on advanced and then click on sideload. Start the adb server and use the command : adb sideload <enter name of zip file here> and hit enter.
Example : adb sideload OEMinfo.zip

Yes, i used it on my phone....Remember, you need to sideload the zip file, using the adb push command will not work.

I'm also L31 Brick after Nougat update...

Did you check if your device is able to connect via adb? use command : adb devices.
You need to install the UPDATE.APP via the three buttons, not the entire zip. It is crucial to flash the OEMinfo. Since you are able to enter TWRP recovery, try flashing the OEMinfo via TWRP.

No conection. Just fastboot mode and twrp. I think the adb sideload not working. The three buttons just show the huawei pticture and stuck on it. Maybe a twrp backup of vendor partition can help, but i don't have one....

Try flashing stock ROM using fastboot
use Huawei update extractor select boot ,system,cust,recovery ,extract them and flash them with fastboot like this
fastboot flash system system.img
fastboot flash boot boot.img etc....
just make sure that you place those img files in same folder as adb is.

Seems like your boot image is damaged but check this thread maybe it helps https://forum.xda-developers.com/p8lite/help/stuck-rescue-mode-screen-please-help-t3244872

usually you should always get into fastboot mode. Turn off your phone, connect it to PC, press power and volume down, after screen turns on release the PowerButton and keep holding VolumeDown, until you are in fastboot mode. Then use fastboot to flash a new boot, recovery and system

Hello all,
I have a similar problem on my old P8 lite phone, but I can enter into fastboot mode. No idea how it turned out like this... I bought a P20 lite and stoped using P8 lite for several months. Some days ago, tried to use the phona and it was unresponsive. Wiped data and some more options, and the phone got stuck on rescue mode.
I've read this and other threads and tried to use fastboot to flash stock ROM again. I downloaded update file, extracted boot.img, system.img, cust.img and recovery.img but when I try, to start flashing boot.img I get:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash boot BOOT.IMG

When I enter fastboot & rescue mode I get the messagem "PHONE Locked" (green letters). What can I do to recover the phone?
TIA for your help.

To force an update, you also need to hold vol+ vol- and power button with update.app in dload folder on your microsd card.

If your phone still boots in rescue mode, then I think the rom you've flashed is not compatible with your phone. As @up said, try to force an update.

Accidentally locked the bootloader by flashing MIUI - what should I do?

Hi,
I've bought my first Xiaomi phone - a second-hand Redmi 3s. It came with the bootloader already unlocked and the Resurrection Remix ROM. While I was playing out with different ROMs, I decided to try out MIUI. (to see how it looks like and at the same time update things that aren't updated when flashing custom ROMs - I planned Lineage OS 16.0 to be my final ROM; to be flashed after I try MIUI)
After flashing MIUI 9.6.1.0 with TWRP it appeared that:
1. The device is locked with a Mi account.
2. The bootloader got locked when flashing MIUI
I tried contacting the previous owner but they don't reply to any kind of contact, so I doubt I'll ever get the bootloader unlock code or the Mi account details from them.
What can I do so that I'm able to use the phone back again?
I'm quite comfortable with Linux and command-line, so command-line fiddling is ok for me. If needed, I also have a Windows VM.

Your phone's bootloader is unlocked. It's MI account that has locked your phone. Call your seller and ask him his mi account password. Put the password and verify. You need to connect to a wifi for this

That's interesting, because when I execute `fastboot oem device-info`, I get:
Code:
(bootloader) Device tampered: false
(bootloader) Device unlocked: false
(bootloader) Device critical unlocked: false
(bootloader) Charger screen enabled: true
I finally managed to contact the previous owner but they refused to help me. ((
Is there any other way to get TWRP & LineageOS flashed when I have no chances of getting the password from the previous owner?

Download the twrp file from the given link. Rename the file to twrp.img. Make a folder in your pc and move the file. Reboot your phone to fastboot mode and connect it with pc. Open folder, press shift+right click. Select command prompt or Windows powershell whatever you have from the context menu and put the following commands.

If the above method doesn't help you then try to flash old miui (miui 8 stable) using fastboot method. Miui 8 doesn't require mi password to boot.

I'll try the other approach. Will MIUI 8.5 Global Stable V8.5.4.0.MALMIED be ok?

Before flashing miui 8 you need to unlock your bootloader. Try this https://forum.xda-developers.com/xiaomi-redmi-3s/themes/redmi-3s-bootloader-cracking-method-t3629496

Hmmm... and would it be possible to somehow copy the MIUI 8.5 zip to the internal storage and then flash with the stock recovery?

Yup possible. Download miui 8 old version like miui 8.2.
Rename file as update.zip and move it to internal storage/sd card. Reboot your phn into recovery mode by pressing volume up+power button. Select english language. Select "install" option using volume buttons and power button. Confirm. Now wait till the process cmplt. After that reboot ur phn. Hope it will work for you

flashed fastboot rom for fixing some volte problem but accidently i clicked on clean all and lock option now my bootloader get locked and it does not unlocking with mi unlock tool it throws the error at 99% that this account cant unlock this device and it fails. now what to do please help... How can i unlock bootloader again.
