[Bricked P9 Plus] - VIE-L29 Possible soft brick, please advise - Huawei P9 Plus Questions & Answers

Most of the time I am the guy helping people out. This time I think I did something pretty dumb.
I have an old "beater" P9 plus that I was using as a casual gaming device. Most of the apps I was using were beginning to no longer be supported because for some reason the device NEVER updated. Any time I check for a possible update the phone stated it was up to date. After much searching I discovered that this device SHOULD have updated quite a few times.
I used firmware finder to find a supported update and the first one went somewhat unexpected. The firmware was downloaded and put in the correct folders but kept failing after 5%. I decided that the next thing to do was to find a cool rom and go through the process of unlocking and installing TWRP. I usually try to install the latest TWRP. This turned out not working at all so I went for an older version and it booted into TWRP, however it found the update and installed it!
I kind of wanted to keep it stock, but updated stock so I went for a bigger upgrade to Android 7 firmware. This only worked partially and (stupid and I know better) forgot to do a backup. I did not know that TWRP was gone and root was gone. The battery died and I rebooted like normal and there was a much improved interface. However, a good bit of stuff stopped working like bluetooth and the boot screen was in red stating the device can't be verified and ended up in something like a NOR905 test keys build. I did a backup, selected a downgrade package that was checked and "updated" to the downgraded firmware through Project Menu. It successfully stated it was 100% complete.
Now it is stuck on the boot screen for an unlocked device.
What works (or is possibly a good thing):
The hardware keys can get me to the bootloader (fastboot)
ADB recognizes the device is in fastboot
Phone is Unlocked
FRP is unlock
What doesn't work:
Everything else. All I have is fastboot and an unlocked bootloader. I can try to flash recovery but that never boots, it just stays suck on the recovery boot screen. The system will not boot at all.

UPDATE:
I broke down and spent the money to use the DC-Phoenix software to unbrick the phone. Several of the options for firmware did NOT work. The one file set that did work was to use this firmware:
VIE-L29_C900B101_Firmware_countryValue_Nonspecific_Android_6.0_EMUI4.1
Then use this as the customization:
update_data_C900B101_hw_default
The phone originally started out as VIE-L29C636B130. This changed it to VIE-L29C900B101 and is on EMUI 4.1 android version 6.
Now the fun part is going to see if I can find a version of TWRP that will work and see if I can root it. Maybe even try a custom ROM. We'll see though. The device is just an old beater for fun. But at least, she's not broken anymore. Guess I'll grab a beer and celebrate my "unbricked" device.

P9 Firmware issues

Hi all,
I'm afraid this is a plea for help!
My P9 (EVA-L09) was working fine with the factory image and i rooted it and it worked fine.
I then attempted to follow the debrand guide to get Android 7 and this worked OK except i was missing the EMUI apps (camera, clock etc). So i updated to another Android 7 image (B822?) at which point i was left with no keyboard.
I then tried to flash the old firmware back on and my phone wouldn't boot.
I followed all of the DC phoenix instructions and it still wouldn't boot so i then used DC phoenix to install the factory image and this worked.
From this point i was able to install B136 and then numerous other versions upto the Android 7 one again but no keyboard once again.
The strange thing is that at this point i can no longer lock or unlock the bootloader it says wrong key, and whenever i do a factory restore i don't get the 'out of box experience' where it asks you to connect to the wifi etc.
I just want i working up to date phone, preferably on Android 7 but if not that is no problem.
Would someone that knows a bit more about android be kind enough to teamveiwer on and help me please?
Thanks
Ben
Also, i have just tried to install the current firmware from the Huawei site and this also fails, sits at 5% installing update and goes nowhere...
Sorry, to correct myself the error when trying to unlock bootloader is "remote: command not allowed"

VIE-L09 seems to be totally screwed!

Hey,
So i used the SRK tool to try and root my VIE-L09C40 (P9 Plus)
Something seemed to happended during the rooting procedure and when i entered e-recovery it said it had to Download a new version, but couldnt connect to internet via wifi.
Any ways it seemed to work after a while but now i have no keyboard at all, so i cant literally start my phone.
it starts, boots the EMUI 5.0 logo and goes through the information a terms, i click the ok button and thats fine.
Next it tells me to sign in to my wifi, i select my wifi and when i go to type the password all i have is google voice as a keyboard, ive searched and searched but cannot find a way around it, also the frp has tripped on phone so i cannot log in to my google account without a keyboard.
How can i get around this?
do i have to flash parts of firmware?
any help would be great, i sent it away to hauwei and they say warranty void due to software!, can only assume something wrong was flashed?
Waiting for phone to be returned now, please help
I had the exact same issue last night as well. No keyboard and only an option to enter details with voice.
Ended up with an essentially bricked phone. Couldn't find any info on the problem online, so I have to improvise.
I'm starting from scratch after formatting etc. using stock oeminfo, recovery and rolling back to Marshmallow. (fingers crossed ADB will let me, because it was giving me errors before)
Will let you know if I'm successful and the steps I took.

Good luck, i did read that it might be possible to install the base firmware back to it and then update again.
Im sure we are not the only people this has happened to and if you succesfully do this, maybe consider making a full step by step guide so to help others.
Fingers crossed
:good:
Will do my best.. So far it's been a major. I've managed to flash a working stock ROM and boot up. But there are a few things to smooth out. Such as, I have no IMEI number now and the build is C900, also the bootloader is modified.
To get it to boot I had to use DC- Phoenix to flash a factory firmware(Chinese) which I had to pay for. Then I flashed a stock vie-l09c432b181 ROM over the top.
To repair the IMEI I'll have to use HCU, which I'll have to pay for as well. But that's ok. If I can get my original IMEI back, I can use the original unlock code I got earlier this year, otherwise I'll have to get a new one based on a new IMEI.
I can repair the bootloader and region code using twrp etc. so that's not a problem.
I'm actually using the phone to write his reply, so I can at least use it.
Once I have it all 100% working I'll try to put together a full step by step.
Cheers.
Well, I have a working phone. But, it'snot stable. Having trouble with mobile connection, sms, mms, 4g etc not staying connected. So wont be doing any write-ups just yet.
Not until it's stable.
I'm wanting to return it to complete stock now. And that requires trying to find an oeminfo file for C706 (New Zealand).
Will add more as I get there. Sorry.
I had the same problems. All I did is updated the phone with the firmware you want via Twrp . Be warned that it will replace the recovery back to stock. Also clear the cache and etc.
I had a similar issue with SRK tool, bootlooping, won't flash new firmwares, lost all the stock apps and diagnostic tools.
I'm now stuck on a TEST-KEYS build with no NFC or Bluetooth.
My solution was to throw the piece of junk in a drawer, forget about it and I went and bought a Pixel XL instead - a phone that is properly supported and gets updates quickly.
After much messing and a headache I finally got to c432b370
And everything back to normal

How did you succeed?
I am stuck on TEST-KEYS but I am not able to flash other roms on it. When I go to recovery, the update process stops after a while

P9(EVA-L09)-Settings missing: Huawei ID, Update Phone

Hi guys,
I've bought an P9 and wanted to get rid of the booting screen with the resellers logo.
So I thought I'd be smart, unlocked the device, flashed TWRP 3.1.1-1-eva.img onto it. Got an SuperSu-file and tried to install it...
I never got to experience the rooted version. Got stuck in a bootloop, somehow got out of it. Logged in, saw an green SuperSu-app, opend it and it saidthe device has to be rooted to use the device, ergo i failed to root it. [Forgot some steps here] and I found myself in another bootloop. A friendly guy suggested to flash these 2 files
[Link-Removed]update.zip
[Link-Removed]update_data_full_hw_eu.zip
which I did with dload. After that, I was still in a bootloop, but with WipeCache I was able to get myself back into my phone [hooraay].
The happyness-phase was a short, because i soon found out, that it doesn't have an keyboard (only googleVoice, should be fun to type in a wifi-password). Huawei-ID tab is also missing (usually located below Accounts), Update Phone, which was between Advanced Settings and About Phone is also missing, and bluetooth doesn't seem to work. That's when I noticed that I'm on NRD90M test-keys build.
After reading some threads here i downloaded rollback from huawei (for west-europe). Now I'm on C900B300 but all settings still missing.
Now I'm here crying for help.
Any suggestions? Please?
Ryan
You got to rebrand your phone.

do you mean, that i have to put the bootlogo back into it?
could be a meanie to do, because it's a swiss brand and I don't think that there's a version here for me to use.
//or do an OEM-Flash, which worked

Phone bricked, won't turn on. Help please!

Hi. So I decided it was time to move to EMUI 9 and after looking at various posts on here I believe the easiest way was to you EMUI Flasher to flash the ROM (coming from 8.1 rooted).
The phone restarted and went to EMUI installer but after 10% or so I got an error. It asked if I wanted to go to erecovery or reboot the device (I think). As far as I was concerned it was only checked that the ROM was OK and hadn't installed anything so I selected reboot. Now the phone won't come on. I've tried holding the power button for an inordinate period of time but it's not happening.
Is there anything I can do?
EDIT - I've tried a different USB port on my PC and can see something in the device manager now ---- Kedacom USB Device > Android Bootloader Interface ---- which gives me a sliver of hope this can be fixed.
EDIT2 - I could send img files through fastboot all day (phone was recognised even though it wouldn't turn on) but couldn't fix this. Gave DC Phoenix a try but no luck there either. Think I've killed it.
EDIT3 - Just in case anyone ever comes across this. I tried below but nothing would work so I contacted someone on Telegram who said the only option was to open the phone up and short it out. No way I was attempting that so I eventually contacted Huawei UK and told them it had died during an update, never let on that it was MY fault! Anyway, they sent out a prepaid envelope to send to a their repair partner. I won't name them here but they have terrible reviews on Yelp so I was a bit apprehensive. I know the phone arrived with them last Friday as I checked the post tracking but I never heard anything from them. Today out of the blue my phone has come back to me in full working order, repaired under warranty! Considering there was only one thing I was really using root for and it was only a slight convenience, I think I'll just leave it as is.
Are you able to flash anything in fastboot?
Are you able to boot to recovery via fastboot? Disconnect the cable after you give the reboot recovery command in fastboot.
You may be able to flash each component of emui, system, vendor, oeminfo, kernel etc. Seems that it's missing most or all of it.
Bootloader sounds like it's intact.
Btw. The easiest way to update to emui would be to wait for an OTA from Huawei.
Personally I don't see a point, pie is not as efficient as Oreo nor does it have any features to merit an upgrade, in fact you would lose features (4k zooming, functional TWRP)

Moto G5s baseband not found (unknown) 😢 IMEI 0 please help

I need help too. So, I own a Moto G5s plus sanders. I unlocked its bootloader the day I got it. Didn't keep any backup and rooted it. I Also installed dot os based on android 11. But my 4G Volte connection was finicky. So, I decided to use a Volte zip patch. But, anyways I flashed the zip via TWRP and tried to reboot. But the phone didn't turn on after that. After a few minutes to my shock I understood that I hardbricked my mobile. No button combos, nothing worked. Anyways in my desperation I found a YouTube video showing the use of blankflash to revive a phone and lo and behold I used the procedure to again restore my device. It booted to the fastboot interface. But my happiness was short lived. My baseband was unknown at this point and the bootloader was I dunno downgraded to 0.5 inplace of 2.12. But, more importantly the unlock status was lost. I unlocked it again and all went well. I could even flashed TWRP. but then I realised I couldn't upgrade my bootloader. I couldn’t do anything. It's always gives a "security downgrade", "preflash validation failed" and "permission denied" error. I even tried RSA official rescue tool from Lenovo but even it was unsuccessful. It was never unsuccessful before that. Not even with a unlocked bootloader. I researched for days and tried custom ROMs. I flashed stock images. Nothing brought back my baseband and IMEI. When I type "fastboot oem unlock critical" it gives me permission denied error with a message. "Need OEM signed bootloader." I think the blankflash bootloader is the root of all evil. I need to change it and therefore I need to enter the edl mode. I have tried all adb commands and fastboot commands. The phone reboots okay after those commands but never goes into edl mode whatsoever. I am also ready to do a controlled hardbrick of my device to go into the edl mode so that I can use my device again with a proper bootloader and a properly working fastboot. Please help
i think this vid will help
Greetings everyone. Sorry if I posted this in the wrong forum. Please move this in appropriate forum if I made a mistake. Believe me, for the last 7 days I have searched all of xda and internet, followed innumerable guides, FAQs and workarounds and none worked. So, as a last resort I am starting this thread
Device: Motorola Moto G5s Plus XT1804 ......4GB _64GB variant
Problem: 1) Baseband not found (unknown) Original Baseband: M8953_52.61.07.98R SANDERS_INDIADSDS_CUST
2) IMEI 0 (Sim cards are not detected).
I bought this refurbished phone about an week ago after my last LG went kaput. I was happy by the build quality of the phone. But it only ran Android 8.1 Oreo. So, I decided to put a custom ROM in it. I am not exactly a newbie to the world of CyanogenMods, Lineage OSes and Pixel Experiences. Or, so I thought. Anyways, after a lot of searching I finally decided on Dot OS 5.2 Official Android 11 version. The ROM looked very pleasing and the reviews looked positive. So, I got the unlock key from Motorola website, unlocked the bootloader, put in official TWRP recovery in it. Everything went like a breeze and in all that excitement I forgot to take a backup of the persist, efs and other partitions. A very costly mistake it seems. DotOS booted fine and looked really fresh till I found that there is a small cross near the SIM card network signal triangle up righthand side corner and the signal is only LTE and not VOLTE. I was using a Vodafone Sim card at the time. Although VOLTE option was enabled in SIM settings. To confirm my doubts regarding VOLTE I switched to a JIO Simcard and alas I was not able to make a call without redirecting through the horrid JIO calling app. VOLTE was indeed not working. So, I looked up for a fix and I found a Volte ZIP file from here https://www.google.com/url?sa=t&sou...0QFnoECBAQAQ&usg=AOvVaw0YgJvCjQWXXV8WQSJkxBOK . This was the starting of my troubles. I flashed the universal VOLTE fix zip from TWRP and it flashed fine. On rebooting, I found to my shock that my phone was not turning on. I pressed and held the power key and there was no sign of life. I couldn’t go to the fastboot bootloader or recovery. Only the white led blinked at the top when connected to the charger. My phone was apparently hard bricked. I searched frantically for a solution in this forum and YouTube wherein I found that one can bring it back to life by doing a blankflash. Found the blankflash file here https://www.google.com/url?sa=t&sou...wQFnoECAsQAQ&usg=AOvVaw1eVdBWGVFr8aiqLdP-ZkeT followed the instructions and it flashed my bricked device back to fastboot. I was relieved for a moment but the next I found that the Bootloader version has downgraded from BL C2 07 to BL C0 05. I knew something was wrong as bootloader downgrade shouldn't be possible. Also the unlock and rooted status were also lost and the baseband was unknown at this point. Anyways the device was recognised as a fastboot device and I tried to flash the stock ROM latest version using the fastboot. But, only then I realised there was something wrong with the bootloader. It gave errors like security downgrade, permission denied, preflash validation failed, remote command failed. At this point I was truly confused and worried. Why would it think the latest bootloader to be a security downgrade to a supposedly old bootloader and prevent me from flashing it. However it did flash the other files like gpt.bin for partition, oem.img, boot.img, system.img sparsechunks and everything else. I booted back to Android 8.1 Oreo and everything seemed working except my IMEI now read zero and my Simcard was not recognised by the device. After that I again unlocked my bootloader. Somehow the original unlock key worked and the bootloader screen said flashing unlocked but the bootloader didn't behave like an unlocked bootloader. The TWRP installed fine but couldn’t install the latest Pixel Experience. The flash screen said PE 11 was for Sanders and my device is (blank no name). I tried both the normal and plus and both behaved similarly. Lineage OS unofficial builds behaved similarly. I again tried Dot OS and Arrow OS and both installed fine except there was no signal. For a moment I tried to forget about the bootloader but concentrated on recovering my IMEI and Baseband but I couldn’t. For nearly 5 days I tried different guides including a detailed guide using Validus Sanders ROM but none worked. My EFS folder has files around 12 megabytes but my Persist seems deleted at zero bytes. The IMEI keeps changing between null, zero and unknown depending on the 20 something ROMs I tasted on this device. At this point, I am at a loss. This was to be my main phone and I am financially crunched. I can't buy another phone right now. I think that blankflash bootloader is corrupted and it is giving me permission denied errors. Even Magisk won't work properly. I even tried using the official rescue and smart assistant tool by Lenovo and it failed at 47 percent. I tried in different computers and Win7 to Win 11 OSes but it was of no use. I also tried getting a QCN file but I couldn’t get one for the device to recover the IMEI. Please suggest something if anyone of you can save this poor device of mine. Thanks in advance

Thanks for the quick reply but my phone is soft bricked now. It was hardbricked and I uses a faulty blankflash bootloader to bring it back to life. My device is softbricked now. I have lost my baseband and I have no IMEI. I cannot take calls and no mobile data. Can you show me a way to go to edl mode in my device. Thanks again.

			
				
can your phone turn on if yes can you root it with magisk
if yes then pls tell me i will tell you
I can do everything except calling and mobile data. Yes, I have rooted with Magisk and have root access. But my baseband is unknown and my IMEI is showing zero. I can't call or access mobile data. Although I can use wifi
I have tried what is shown in this video already. Didn't work
I think the blank flash bootloader was corrupt or of a different region.
so go to magisk manager and on top-right corner you will see setting click the button right next to it and click on reboot to edl
I didn't even knew that. Trying asap. Will update
Doesn’t work. Reboots back to system.
Updated Magisk to latest and tried both edl and download mode like you said brother. Everytime boots back to system. Am I missing something. The phone was not connected to the PC at the time
I am on stock Oreo now. Rooted and twrp installed
An interesting observation while installing Xposed, it gave an error that the device is not rooted properly
I have an untouched dump file for my model. The whole thing. Could you please guide me how I can restore my smartphone from that.
can you flash it through adb sideload fastboot twrp etc
I don't know but I sold the device. I bought a new one. Thanks @Raggaov for the help.
you're welcome
