Cant unroot and Relock P10 Plus - 10hrs trying :( - Huawei P10 Questions & Answers

Hi All
Sorry to drop in your forums and start off with problems but yea, need help. I spent the whole day (10hrs no exaggeration) trying all sorts of methods mostly from this forum and i am still stuck.
I had problems with my P10 plus so long story short i decided to root it etc, it is still working ok but many of my day day apps refuse to work rooted so im happy to go back to stock again.
But i seem stuck in loop of problems:
- Tried dload folder method but update always fails
- Tried HWOTA folder method but again fails
- Tried to relock bootloader but i get "command not allowed"
- Tried and tried to remove root, but SuperSU has binary occupied error, no SU files etc to delete either (not sure how i rooted i followed some guide)
- Closest i though i got to success was using Firmware Finder app and proxy, it fully downloaded and rebooted to install but again failed on reboot
- Cant flash recovery with anything else or boot as the "command not allowed" error again
Heres a screenshot of my ADB errors:

Every post ive read i seem to stumble:
"remove root by returning to stock" - Cant get back to stock.
I tried this often recommended post https://forum.xda-developers.com/hu...ution-bl-unlockedfrp-locked-fastboot-t3684302 but again cant relock as is says root is risk, and cant seem to remove root either.
Someone help me please, literally aching all over as sat here all day!

I feel for you, I had the same problems, tried every suggestion I found. I tried HWOTA version. 2 times it didn't work, but 3rd time it did. It can lock bootloader again in process but it's only to unlock and do again. I now did the HWOTA solution 2 times with success. I had the HWOTA folder and 3 files on me external SD card when I did it. Good luck!!!

Do a complete factory reset, downgrade to Nougat, factory reset again for safety, lock bootloader, update to Oreo.
How to downgrade is written in a tutorial here in this forum. But you're in the wrong forum, this is for P10 VTR, you have a P10 Plus VKY and there's a special XDA forum for that - don't know why so many people can't read and/or Google correctly to find the right forum for their devices...

Impossible to unlock bootloader (Asus Zenfone Go (ZB452KG))

Hi,
I passed the last 2 days reading and reading tutorials on internet and trying to find a way to install the TWRP so I can install a Custom ROM, and for what seems I need have the bootloader unlocked, which Im trying but the option dont appear under Dev options and it doesnt let me use the oldest firmware since the one installed is newer...
So Im trying to see if I get the flash tool for it, but I only find those scam websites where I need install or refill some form with my data.
Does anyone have the tools needed to flash it ? Thanks in advance
PS: I searched in the forum and the posts I found wasnt usefull to me, and everytime I try to flash the TWRP, it appears in my cmd windows: "writing recovery" but stay like this all time, after 1h I needed restart the phone

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"

Stuck on honor logo

Ive had this problem for ages and tried everything i can think of. hopefully by now someone has experienced the same problem and solved it.
*My phone is stuck on honor boot logo
*i can access e-recovery
*i can access stock recovery
*i can access fastboot and device is recognised on my laptop
* i can wipe cache and factory reset successully and have done many times
*i can and have used the dload (3 button method) to flash stock rom successfully
Now the problem is that although i have flashed the earliest stock rom NEM-L51C432B102 it fails saying incorrect package!!!i think this is because my phone came with B103 or B104 and you can only flash from what your phone originally had and up.
I have flashed NEM-L51C432b120 and also NEM-L51C432b130 and although it says successful it reboots and remains stuck on honor boot logo!
I have entered fastboot and i can issue commands but they all fail saying REMOTE COMMAND NOT ALLOWED.
I can't use ADB because it doesn't recognise my device. Obviously ADB and FASTBOOT wont work because i can't access developper options and select enable USB debugging or OEM Unlock because the phone is stuck on honor boot logo.
Also my bootloader must be locked. I have the unlock code but i can't issue the command FASTBOOT OEM UNLOCK XXXXXXXXXXXXXXX because as mentioned before it says FAILED REMOTE COMMAND NOT ALLOWED.
I have even tried flashing rollback packages(there isnt one for NEM-L51)for other models, followed by flashing stock rom for my model device.
When i bought the phone it came with either the B103 or B104 package but after months of searching i can't find on the internet.
Is my phone a lost cause??? is it hard bricked? So i am praying that there is a guru out there who can solve this very strange problem.
Many thanks in advance.

Oh well. Seriously this is the same issue my frn asked me to help. This is soo serious that we can only unbrick through update.app or else service center. Since u said dload method works but stucks device on bootlogo. U need to visit service center if under Warranty

Flash these files and it should, most probably, be fine.
use dload method as given here- https://forum.xda-developers.com/showpost.php?p=73954487&postcount=240
as there are many different opinions on this method of using only update.app file but thats not true and it should be all the files.
Main file - http://update.hicloud.com:8180/TDS/data/files/p3/s15/G1165/g104/v71812/f1/full/update.zip
Data file- http://update.hicloud.com:8180/TDS/...1812/f1/full/hw/eu/update_data_full_hw_eu.zip
Flash both the files in order. 1st file will restore your system but then you need to have 2nd file so that apps are installed and all working fine.
After 1st file, it may reboot on its own and stuck on honor logo, reboot to recovery and then do factory reset, it will be fine.
Then let it boot to set up. Dont set your phone. Shutdown and flash the 2nd file.
boot and set up.
Good luck. Please provide feedback once done. In case of further issue, let me know and will dig more into this.
Oh this is hard.

you cant follow simple instructions? you shouldnt be on this forum if youre not ready to lose data or brick your device.
Thanks for your input so far people. Much appreciated. @shashank1320 I am downloading the files you suggested and will flash them exactly according to your instructions. I will get back to you in a couple of days with the result. Fingers crossed.

Unfortunately my warranty has expired. The annoying thing is that if i had sent my device off six months ago when this first happened it would still be under warranty but in the UK there is only 1 service center, yes 1, and its hundreds of miles away! So i figured i could solve it myself. You live and learn.
Hey there everyone. I still havent managed to solve the issue with my device and its not through lack of trying. I have re downloaded all of the stock firmwares that you can possibly find on the internet. I also found one ive necer seen before. Its a full service repair b355. Fingers crossed, a miracle might happen and it will just boot up like when i first bought it. to begin with tho, i'm going to start with b102 and work through them b120, b130 ,b130rollback ,b350(beta), b350, b355 and then the b355 full service repair! I also got a couple of rollback packages(around 80mb) if all else fails.
I know, i'm nuts!! Finally before i admit defeat i'm going to part with £15 to buy credits for the dc-unlocker and dcPhoenx programs. From what ive read it has a good chance of solving it. I've taken soooo long before considering this option because i think its wrong that someone(s) is making loads of money from this. Why havent huawei/honor included a similar program in hi-suite. Anyway ive gone off on a tangent.
One last question though. Strangely enough i only just thought of it recently....
Is it a necessity to have your sim card in the tray as well as the sd-card????? All this time i havent had a sim in the phone as its in a crappy old one so i can still communicate with the world!!!!
Thank you to everyone for taking your time to read this. I hope a solution is possible.

No need of sim card in tray while using dload. Just sd card is fine. Let me go through it again and try to help before you go for 15 dollars for dc phoenix

Did you flash those files i given? If not can try. Else i will have to look for other alternative
yeah i downloaded those files you had mentioned in your post and followed the instructions to the letter.
I've got a suggestion if you have tried all these above.
Can you try the following on ADB and then try to unlock OEM again.
fastboot oem relock YourUnlockCode
I've done the same and it helped, even when bootloader displayed UNLOCKED. Please try it. :good::good:

@shashank1320 Hi, i have similar problem with my NEM-L21 device... I tried to flash the Elite ROM v5.1 but i didnt succeed so i decided to restore my old rom from backup with TWRP. When i restored it it just didnt load. It was stuck on honor logo for a long time. I tried the dload method many times but nothing worked so far. I even tried unbrick it with HUAWEI Multi-tool but it also didnt worked.
Now i cant acces anything, just fastboot. I cant even turn off the device. Please can you help me somehow?

Try unlocking the bootloader again even if it is unlocked. It will factory reset the device and it should boot fine. Have stuck on this many a time and this was the method i followed.

Need help fixing phone

Good day. I have the Huawei P9 EVA-L09 model and my build number is C432B386.
I tried rooting my phone a couple of months ago and failed, so I gave up. Yesterday I tried flashing TWRP, it said it was successful, but while trying to enter it, I always get the "Your device can't be trusted... Your device is booting now." I completely gave up on rooting or flashing another ROM so I went to relock my bootloader. It was successful, but while the factory reset part, I got an error in eRecovery (Package download failed or something like that) and after that I restarted my phone and it was factory reseted. My problem is, eRecovery now says that my partition is heavily damaged and needs a wipe. So I tried doing that and it failed again. Now I'm left with a Huawei P9 that doesn't have any stock apps and I can't activate bluetooth (and who knows what else doesn't work but I haven't discovered yet)
If anyone could help, I would be grateful. I don't even know where to start fixing this. I just want my phone back or the MagicRainbow v3 ROM, but I'm not skilled enough to fix this alone.
I am just a beginner, too, so maybe you should wait for more experienced answers...
I would try to find the original images and flash them via fastboot. As far as I understand it, this would fix the corrupted partition.
But again, I still have little knowledge and an almost bricked phone!

The partition is fixed, thank you. But I still have a lot of problems. My bluetooth won't work and I no longer have any stock apps. I don't know what to do...
Could you tell we, which ROM you have installed? Is it the stock-ROM, or MagicRainbow? If it is a custom ROM you might need a gapps-package like in LineageOS...
If you want to get back to stock, you can create a dload folder in your sdcard and put the update app in it. Than a restart with a special key combination (power, vol down and vol up I believe) will install it.
I'd strongly advice you to read in this forum how to do this, as you need the right recovery corresponding to your ROM, as far as I understood.
I did this with a wrong ROM and now have a phone with no keyboard, only google voice recognition... So be careful!
I would download and install by DLOAD folder the downgrade package... Then flash a full firmware b136 or 182
But you have to be on cust c432 as far as I know.
There are a lot of info regarding dowgarde to MM. Look for it and take your time to be sure the steps to follow

Soft Bricked P9 L09 C150

UPDATE 2: Some things can not be fixed without proper tool. All i am left is to send it to service.
Which i did. Talked with a guy, explained and he told me he need to see it and test it with some tools. If can be fixed COOL if not i will sell it for parts and **** myself. Apperently some things need to be left to proffesionals.
PS. Will never get Huawei again
UPDATE: After trial and error i have TWRP instaled. Problem is i can't flash any rom because i got failed to mount /cust ,/vendor/ product (invalind argument) error. Also can't find stock flash rom for L09C150
Hello, i have problem with my phone, and this is 2nd night i spend working on it. Would appreciate any help!
Phone before trying to do anything: L09C150B367, Phone is from Hungary on Telekom (Pink T logo).
Tried to follow debranding guide (https://forum.xda-developers.com/p9/how-to/guide-debranding-to-c432-updating-to-t3551523) because i am sick of not having updated and unlocked global version. It's been long since i did anything with android and root so i tried and found guides on XDA.
Steps i did: found code for bootloaded, unlocked bootloader with SRK tool and instaled TWRP. Downloaded C432 and placed to SD. Trying to force update with Vol+,-, and power combo but update stop after 5% and say invalid software version. Somewhere i read that root is needed. Tried to root with SRK (Couple of times and different guides), not working for some reason. Phone is still unlocked with TWRP. Read somewhere (it was 3/4 am this night) that full wipe might solve it (note, i could boot into old OS). Did full wipe on TWRP and voila, not working. Can't even log on because no OS detected. Tried to find stock firmware to flash from SD card, no luck. All links i found either don't work or my recovery have ,,not correct version" error.
Now i have unlocked bootloader, custom TWRP recovery and no OS..essencially highteck-flashy brick.
What i want: Stock unbranded EU firmware.
Ps. Only phone, i refuse to burn 250e
If you are kind and free and KNOW how to do this, you can contact me via Discord and talk me trought this!
