Hello, a friend asked me for help unbricking his phone, apparently he downgraded to marshmallow, had some wifi troubles, tried to upgrade back to nougat and bricked the phone, the phone can enter fastboot and recovery mode but I can't flash the stock firmware because it gives me the verification failed message when trying to flash the files, I have been reading lots of tutorials but I can't get any of them working, when trying the blank flash thing the CMD window just stays in the waiting for device message.
Any help would be appreciated, thanks in advance.

If device is able to boot into bootloader, then blankflash will not work..
What is version of firmware you are trying ?
Currently this is latest firmware >> https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138
Validation or bad key id errors are ignorable, ignore them.
Just make sure you get OKAY at end of Command..
If you get any error, post cmd screenshot or copy test and pasre here..

Hello,
I own a Huawei P8 L09, bootloader unlocked, rooted and with TWRP recovery.
I tried this morning to flash a new rom using TWRP recovery.
Problem is that I do believe I wiped to many partitions and I ended up with a bootloop.
I could at first access 3 times the emui erecovery (btw, Wifi recovery failed) but not anymore (is it related to the battery level ? I don't know how much I still have)
Following a lot of threads here and on some other forums (I've been searching now for approx. 7 hours...) :
I downloaded a update stock ROM (B170 something), I extracted Boot, System, Recovery and Cust
I entered bootloader mode (it's the only mode I can go to; recovery No, Download mode neither)
and on my computer I typed in the cmd "fastboot flash recovery recovery.img" same with system, cust and boot.
All of them said "Okay" but the bootloop is still there and I can't acess any other mode or shut the device off.
Also, my bootloader indicate that i'm "unlocked" but when I try to do something as :
"fastboot erase cache" it says "remote: not allowed" or something like that.
I tried the SD card flash method but I can't even acess the 3-button mode (doesn't work - bootloop again).
Finally, I've got 2 questions :
1) Is there a solution ? Is there/was there anybody in the same situation ?
2) Does the battery level influence wether I may or not enter any mode ? like b.e. under 30% I can't access recovery or something like that ?
Thanks in advance for your help and sorry for my bad english.
Greetings from Belgium !

Hi!
I have the same situation as you do, All i know is that you can access the eRecovery only if you're plugged in.
But it's completely useless. Have you found any solutions yet?
Edit:
i struggled and i'm still struggling but i figured out that I need the recovery and boot img of the version i was on previously. In my case that is B350.
The main mirror is down but i managed to find another one: https://mega.nz/#!NAcgQY7Y!I4eRfkaq62J31csv_wZ8_nTzmUbWPX71JUicDysjus8
after flashing them i was able to partially flash (using vol+-&pwr) B170 (it only went up to 90% with my USB attached, fails without USB)
At my surprise it booted B170 even if it didn't complete, however right now it keeps rebooting every minute. I'll update if i manage to fix this
I have the same problem as you both. To flash boot.img and other files by fastboot we need to unlock bootloader. To unlock bootloader we need to have Imei, Product Id and SN, but I can't read it because phone won't turn on.
Anyone know how to get this info?
you can read these info from the packaging box!
I managed to fix my issues (i believe) by continuously flashing and flashing versions. I never really managed to fully OTA update to 100% due to some "CUST error" but from B350 i managed to "update" to B170, then to B200, then to B321a.
Now i just installed TWRP and rooted it and on the process of installing xposed (if possible).
I wasted a good 6-7 hours on everything already
Well now I actually sent my phone in repair, given that it still was under warranty.
If they return it unrepeared, i will try it your way, Nikooo777. Thanks.

Hello everyone, I have a huawei p8 vodafone it branded.
I decided to root it, unblocked the bootloader and everything was good so far...
I tried to flash a custom recovery but failed for some reason and I decided to stick with stock recovery.
Now I installed an app as system app and my phone got bricked. my fault..
At first It went trough a bootloop and I was not able to access the huawei recovery or the fastboot, after a while it started to boot into a error message where it was saying that it was impossible to read user data partition, and give me some choices like backup, update to the latest version, or data factory.. I choose data factory twice but it went trough a bootloop again only to give me back to the same page after a while.
I can access huawei erecovery but it gives me getting info package failed when it says that I have to update it with wifi.
I can access fastboot mode and it says me that the phone is unlocked.
I really don't know what to do as I'm not expert, I tried to read various topics but never saw anyone with this message where it was saying impossible to read user data partition..
I had emui 3.1 5.1.1 with vodafone it brand... In case I have to flash it which firmware I should look for? Or is there a way to get my phone alive again without flashing?

Hey thank you silvano, can you tell me which firmware I need to flash it? Is it okay if I use a b170 even if I had the 5.1.1 emui 3.1 version?
Nothing, I can't seem to make it work, I've flashed the boot.img recovery.img system.img and cust.img successfully(b170) but still stuck in bootloop, I can enter bootloader mode, and recovery.. but when I enter recovery it says me that I need to update it and I can't update it because it says me that getting info package failed... tried with different wifis, same result..... The excatly same thing happens with the b132 stock rom too and I cant factory reset or even wipe cache if I dont make this update first as is the only option avaible on huawei eRecovery.
As last attemp I tried to force an upgrade with putting UPDATE.APP inside the sdcard and press vol up vol down and power for booting but this combination of buttons doesnt work...
I'm hopeless, I really don't know what to do... any help would be much appreciated
Hi!
Got a problem, need to send my p9 lite to service bc it fell with me into water. it still works, but I assume a chip is frozen because neither the wifi nor bluetooth can be turned on. I'm afraid theyre not fixing my problem because I unlocked it.
I flashed twrp recovery, rooted, but already flashed the stock rom and unroot again.
When I tried to relock with adb and bootloader code, I got the error code root risk is too high
Tried to install other stock roms again and a lot of stuff, but none of it worked. So I tried to relock via dc-unlocker. com but didnt work. But now it says when I restart "your device has failed verification and may not work properly." instead of "Your device has been unlocked and can't be trusted." and when I tried to use adb to relock with the bootloader code it says "remote: stat not match" ~ got a new bootloader code??
I'm desperate, can anyone help me?
put update.app into dload folder in micro sd card and try 3 button method.
hey i have just the same problem and when i try the 3 button method i get the error software install failed.
but i have no revolution twrp any more and i think also no erecovery beacuse i cant do a factory reset when i tried to enter erecovery with power button , volume + button then i go automatic to software update and at the 5% i get the error software install failed i hope some body get a solution to fix my phone without dc-unlocker
ps i was on android nougat but i think there any os now because the phone dont boot sorry for my bad english hahah
Urgent help needed as I'm leaving the country at the end of the week o any help is appreciated!
Just successfully rooted my device:
Black, Unlocked, PRA-LX1, UK, Dual SIM
After doing so successfully, I attempted to flash LineageOS from the following link:
https://forum.xda-developers.com/p8lite/p8-lite-2017-development/rom-lineageos-15-1-hi6250-devices-t3811583
Although when I completed Step 6 on the Installation guide and rebooted the phone, I started seeing the message:
------------------
ERROR MODE
Attention!
Please update system again
(Green Android picture)
Error!
Func NO : 11 (recovery image)
Error NO : 2 (load failed!)
------------------
Despite this, I didn't receive a box with my phone due to being second hand, and I didn't see the model number on the receipt as it was from a reselling store. I didn't remember to note down the specific model number
It'd be extremely helpful if someone could possibly help just from the device description above as I'm not sure if it's safe for me to just attempt to flash every stock rom for every other LX1 device out there.
---------------------------------------------------------------
Update:
To restore this, I connected via fastboot with a working USB & flashed an original stock recovery in the video found here
(Just in case their download link ever goes down, I have uploaded the same copy to my MEGA, found here)
The recovery installed fine when using the command
fastboot flash recovery oeminfo.img
Click to expand...
Click to collapse
Whenever trying to flash any other recovery such as twrp before this fastboot stuck on a loading icon.
The stock recovery seems to be downloading the original firmware, too.
PRA-LX1C432B202 is presumably the model.
Both the bootloader and FRA were unlocked when everything else was inaccessible.
Looks like the custom ROM's recovery that you've flashed is not compatible with PRA-LX1. Try to flash stock recovery. If not working, then flash stock firmware.
Thanks @Botar230!
I didn't see your comment until just now after deciding to edit this post since I've gotten a step closer to restoring my device.
Your solution was the method I used although I didn't know my phone model, so I found a random solution which just worked for my device, and the eRecovery seems to be downloading the stock firmware anyways. Thanks again
Before flashing this lineage os you should update to EMUI8 to get treble support, i suppose you was running EMUI5, hence the error mode.
Thank you in advance for any help you can provide.
I successfully rooted my Zenfone 3 Max (ZC520TL) using Magisk, but wanted to restore the phone back to its factory firmware. I used the uninstall option in Magisk but this reported that it could not find the backup boot image. Unfortunately I then made the mistake of following unroot steps on other sites rather than this excellent resource. Long story short I somehow managed to lock the bootloader again so when I try to use fastboot to flash any image I get the error "FAILED (remote: not allowed in locked state)".
When I turn on the phone, on the ASUS splash screen it says...
Red State
Your device has failed verification and may not work properly
Your device will boot in 5 seconds
… ie boot loop.
Q) What can I do to get my phone usable again? I searched this site and found lots of info on how to unlock the bootloader and how to root, but nothing about how to stop the boot loop.
I do have access to the Recovery mode and see options such as "Apply update from ADB" and "Apply update from SD card" but I am unsure if these will help?
Thanks again for any help and/or links to solutions on this site that I missed.
I was caught in similar situation, due to unsuccessful flashing using asus flashtool, I ended up flashing stock firmware (not the raw firmware) via recovery and everything was back to normal.
Thank you... but...

Thank you @sanctitude888 so much for your help. I'm new to rooting but keen to learn. What's the difference between "stock" firmware and "raw" firmware? For example I can download the device firmware from ASUS and extract the boot.img file (ASUS no longer provides the recovery.img file) but is this considered "stock" firmware or "raw" firmware?
You also mentioned you flashed via recovery. In Recovery mode I see multiple options such as "Apply update from ADB", "Apply update from SD card", "Mount /system", etc. Could you please be more specific on how you did the recovery please?
Thank you for your help.
Kind Regards
