Sadly I tried flashing multiple system .img and TWRP .img with no luck. The phone ran out of battery and it won't even charge, it goes straight to a screen that says "Your Phone Has Been Unlocked and can not be trusted, etc" I'm completely at a loss.

Ok, your bootloader is unlocked and the black screen with red warning is normal.
Find a recovery for you actual buggy version (Nougat?).
Boot on bootloader and use ADB command:
"fastboot flash recovery recovery.img"
And past the return here.

That's what I did. Turns out the phone was out of battery that's why it wouldn't Boot into recovery. I followed the guide mentioned above and then phone is working flawlessly once again. Thank you all for your time and help!

Guys help us about the camera. I am in the same exact situation. @BadWolfYe and your product_V3 doesnt fix the camera for me, VNS-L21.
And for the recovery - http://forum.xda-developers.com/hua...ecovery-twrp-3-0-2-android-nougat-03-t3511937 - use adb flash it.

You'll have to go the hard route. You'll find all the required files in the ROM section.
Download any Nougat.zip (329 worked for me, 336 did not). Unzip. You'll get the update.app.
Download the second file with all the missing apps. Do not unzip. Maybe rename to something shorter like data.zip.
Download Revolution Recovery for Nougat. Unzip. You get the recovery.img. RENAME to something like revolution.img.
Open update.app in Huawei Update Extracor. Extract recovery.img, boot.img and system.img to wherever your fastboot.exe is. It's practical to put it all in one directory so you don't have to type long paths.
Now, careful...
Go into Fastboot. If Vol- + Power doesn't work, let it boot into eRecovery, press Vol- and tap Reboot. There you are.
Open a command window in the dir with fastboot.exe and the .img files (right click, Open Command Window)
fastboot flash boot boot.img
.... OK
fastboot flash system system.img
.... sparse 1/5 or something, this takes a bit of time.
fastboot flash revolution.img
.... OK
Now DO NOT REBOOT into System. Hold Vol+ + Power while still in Fastboot. It'll boot into Revolution eventually. Tap Advanced, ADB Sideload. Swipe.
Back in your command window, type:
adb sideload second_file.zip
... working... this'll take a bit. There might be an error message like 'could not mount /data'. Doesn't matter at this point.
When done, type
fastboot flash recovery recovery.img (this is the stock recovery you extracted from update.app)
... OK
Reboot to recovery from Revolution.
Do factory reset. Note: If you don't do this last step, there will be a bootloop.
Reboot. The system should now boot up normally. At least it did for me... good luck.

I did this too. Only way to fix it is to downgrade to MM (instructions are in the N install thread). I then unlocked the bootloader, booted to fastboot, flashed Meticulus recovery. Once you're here, the important thing is to flash the update.zip and appropriate .Zip file for your device. Took me a while to find it but Meticulus has a post in Spanish with all of them for each type of P9 lite - there's one for the VNS-L23 there. Flash the update.zip and then device zip (in that order) and reboot. It'll work.
This phone is harder to flash Roms than others I've had in the past... It's important to do things in the right order.
Here's the link I was referring to: http://www.htcmania.com/showthread.php?t=1265029

First thing when you want to do something (TWRP, root, custom ROM etc.) with your phone is: UNLOCK BOOTLOADER!
Without unlocked bootloader is not hard to do, you not even try, because it is impossible...

For unlock bootloader you only need you phone to boot into bootloader...
You say "now my phone is only booting to erecovery and bootloader"

You have to saved anywhere first time you have'it!
That is the first rule!
Once you debranded your phone that Device ID is change,
so even your phone boot ok and you obtain a Device ID is not the same
with the one saved in the Huawei databases...
So, procedure to obtain the bootloader unlock code is ended in error...

[SOLUTION] How to get out of the soft bricks and bootloops

If your device has unlocked boot loader and for some reason you just tried to flash something and it went wrong then there is no problem guys. The simplest solution if you are stuck on boot is that press vol down and power key for 3 minutes. It will work and will reboot. No before rebooting into the phone just go to the recovery by pressing the vol up key on boot process. This will load you in eRecovery of huawei. From there you can power off the phone. Now take out the sd card and put the desired rom in it. If you want stock android then you need to put UPDATE.APP in the dload folder in sd card and then go to eRecovery again. If you have a twrp recovery then you can go to stock as well and switch to a custom rom as well. Just place custom rom zip file and gapps zip file and flash it through twrp recovery.
For custom roms and recover visit :

Thank you if I ever need it. Maybe someone that has needed to use this fix will confirm that it works.

Well, it doesn't work for me... I held those buttons for 5 minutes, and all my phone did was to reboot about every15 seconds to the "Your device is booting now..."
I also tried with other button combos without any luck.

Download the SRK Tool for huawei p9 lite and unlock bootloader ( if required ). Then flash twrp recovery and then root the device. You might have made a mistake between any one of the processes. Also check if the OEM is unlocked in device developer options

As written in the other thread, the phone boot loops, and I only have access to fastboot. It refuses to go into recovery and can not boot normally.
I can't flash TWRP as frp is locked.
I tried messing around with Miracle Loader 2.27A, but it can't find my phone (maybe I am doing something wrong).

Restart only in Recovery

Hi all,
after unlocked the Bootloader i flashed the recovery as usual:
fastboot flash recovery twrp-3.1.0-0-n3-potter.img
The terminal not started more. No problem, I wanted to install LOS 14.1!
Booted to recovery, installed LOS, Gapps, etc and restarted.
Now every time I try to boot the phone normally I get the Recovery, have to say to restart to bootloader then say to Start.
Not a big problem, simply strange!
Any suggestion on how to repair the correct boot sequence?
Thanks
Connect your phone to PC in bootloader mode and type "fastboot continue" command in ADB.

Are you getting recovery (TWRP) or the bootloader?
If the bootloader, then enter "fastboot oem fb_mode_clear" and reboot.

bootloop after unlocking bootloader and flashing TWRP

Hello,
I have lenovo k4 note 32GB ROM, 2GB RAM with stock 6.0 MM. I've unlocked the bootloader with the command ''fastboot flashing unlock'', confirmed it by pressing volume down and returned to fastboot, then successfully flashed twrp from here https://forum.xda-developers.com/k4-note/development/recovery-twrp-3-0-2-0-touch-recovery-t3530374 , i used the latest version 3.2.1. Now the phone remains in bootloop. After pressing vol- with pwr it enters meta mode for a few seconds but then returns to bootloop again. Attempts to anything lead to bootloop. My computer does not recognise it. Is there anything I can do to revive it? Maybe SP flashtool? I have not tried that yet. Help me please, I would be very thankful for any help.
Thank you

1. Flash stock version (This will lock you bootloader again).
2. Unlock bootloader and let it reboot (donot flash recovery now)
3. It will wipe the device and boots up.
4. After the boot is successful, go back to fastboot and flash recovery.

Flash full stock rom, not just recovery using flashtool. You can't flash recovery alone at this point.
For flashtool, you need to power off the mobile completely.

Thank you soooo much, you helped me a lot. The phone is now running!
Btw, before I restored it, I got into TWRP once, I think i pressed some of the nav buttons to get there. But in mount partitions system was missing and data partition was showing 0B, so something was definitely wrong.
Gonna try flashing it again, this time I'll reboot after unlocking bootloader and only then flash. I hope this time I'll succeed

Huawei P10 Lite - Bricked Device

Hello everyone.
I Have Huawei P10 Lite WAS-LX1A and I accidentally bricked my device.
I was using TWRP to install a rom, and I wipped my system but the rom couldn't be installed for some reason. So I thought my TWRP Version had a problem, so I tried with bootloader to istall a new TWRP.
In adb I pressed:
fastboot flash recovery TWRP_by_GreatSlon.img
Click to expand...
Click to collapse
and then
fastboot flash recovery custom_boot_decryptdata_b130
Click to expand...
Click to collapse
But now, it doesn't load TWRP at all when I press vulume up + power button. I am stuck with out TWRP and with out an OS.
And I can't enter bootloader to install a new TWRP. Is there anything I can do?
I do have a laptop and an SD Card and my Bootloader is unlocked. Phone Unlocked and FRP Unlock are red, so maybe there is a way to save my phone please? I need help please . Sorry if I am not explaining very good and if I don't write correctly, I'ts because I am very very sad . Please someone tell me there is a way to fix it. Maybe dload? But I cannot find any file that it fits.. Thanks in advance.
I found this youtu.be/pkWSDlrLmns and I intalled a new TWRP. But I still cannot find any ROM to install. Any help please?

you flashed twrp in recovery partition and after that, you flashed "custom_boot_decryptdata" also in recovery partition. so, twrp was overwritten. that's the reason why it doesn't work now. are you able to enter fastboot? (VOL- & power button)?
are you on emui5 or emui8?
if you can enter fastboot mode, flash twrp again.

Try to flash all partitions from a service rom.
I have the Same Problem. Only dark screen with fastboot connection.
(Sorry for the very late reply) I could enter fastboot using a pc, and then flashed a different twrp and costum rom.
Everything was okay. But, lately my rom started having network problems and I decided to flash an another rom..
But when I did, something wrong happened and now I am without twrp, without rom and with phone and frp locked.
My destiny is to brick my device and go to imposimple position, isn't it? I don't have my unlocked code so I cannot unlock my bootloader. I paid and tried dc unlocker to unlock my phone, but after plug-unplug it stopped being unlocked again and my money for dc unlocker gone for nothing and I am not willing to pay again for something like that. Any ideas to unlock my phone?
I sent an email and message to Huawei to see if they can give me the code, but idk if they will do. Any suggestions?
This post can be locked. This thread continues here. As for the Huawei, they respond that they don't give the unlock code anymore..
