My Huawei P9 is stuck in bootloop i think?

Hi, i have tried to remove my root and unlocked bootloader as I didnt think they were correctly installed in the first place. Also I wanted to install a new oem update that it keep reminding me of in the background. So now after doing alot of things found in forums and youtube I have come to an end point were the phone just comes to the bootscreen, "your devise has been unlocked and cant be trusted." from here it is just stuck with the "your devise is now booting..." then nothing happens so I realy need help now, otherwise I will have to buy a new phone within the next days.. I cant still get into the twrp and format/wipe data etc, so is it something in here I need to fix then?
Anyone that can please help me out a bit?
Regards Kristoffer

I'm having the same issue. I am unable to flash a custom rom or an official rom. One issue I am having is that I can not relock the bootloader as I get an command not allowed. Please can someone help with this issue.
Thanks

But I cant get into the twrp anymore, only the fastboot and recue mode and the huawei erecovery mode, and in this the wifi just gives me failed to download the package or something like that.... ://

I managed to get in recovery by running the oem unlock. The problem I have is that I am unable to lock the bootloader again.
I really want to get the phone working again. I don't want to have to send the device to a Huawei Service Centre since the bootloader has been unlocked.
I really hope someone can help us all get the device back to stock firmware.
Thanks

How did you get to the recovery mode? I cant get to the twrp anymore, i think i did something wrong and wiped data or formated it so now i can only se bootup screen, or huawei logo or get to fastboot and rescue mode. There it says phone unlocked and frp (or something) in green letters lock....? And also the huawei erecovery which i cant do anything in...

I run fastboot oem unlock and flashed twrp using fastboot.
I have managed to flash update.app, Default_hw.app, Default_normal.app and Default_eu.app using an app called DC Phoenix, but now when the phone boots it goes in to eRecovery and the touchscreen doesn't work. Even when I flash twrp again the touchscreen still doesn't work.
Please can someone advise what to do to get the touchscreen and the other phone back to normal.
Thanks

Were i find a link for step by step rooting my huawei p9 lite. I have company from amateurs pretty good ones. So i cant make mistakes. Thnx for the help...rock the world wild and free whopppaaa

P9 Bricked, Bootloader Locked. No TWRP Installed. FML (Send Help)

Think I did the title pretty well, I can only access fastboot (Before you say anything I've already tried this guide:http://forum.xda-developers.com/hua...ow-to-unbrick-huawei-p8-failed-t3260704/page1) all it gets me is the screen to light up (black) that's it. At this point I have no clue how to bring it back, any useful tips or ideas would always be appreciated. Thanks.
EDIT: It would be helpful if anyone knew a way to unlock the bootloader through fastboot
EDIT: nvm unlocked the bootloader through adb
EDIT:Installed TWRP through FASTBOOT
EDIT: Had the future rom downloaded, installed through SD card. DEVICE BOOTS.
EDIT: Tried dload method, went back to square 1 (Device would only backlit screen on boot, bootloader locked) Repeated steps and used the Huawei P9 Updater 2.0 by Hajuuk (Godbless) IT WORKS. Currently on C185B170 will update to B180 and from there to Android N. IF anyone has a similar problem feel free to ask.

Hi, I have problem. I have two Huawei P9. One is L19 and the other is L09.
My L19 is the C900
My L09 I do not remember what it is ... the problem is that it is no system, it only turns on fastboot recovery mode. I've tried combo keys with dload but it does not work or does not recognize. By Hisuite says that the model is not supported. Finally I tried the Firmware Update program by hajuuk https://forum.xda-developers.com/p9-...dater-t3435878 I used several firmwares inside the L09 option but in the middle of the installation it gives error.
I need to find a way to enable the OEM so I can flash boot.img, recovery.img and system.img because I can not flash anything at the momento because it gives the Not Allowed command.
The status is Bootloader locked and FRP locked.
I do not know what to do, I have no ideas.

I think there is not solution for this problem. We have to wait. (I have the same problem but in Al00 running Al19 rom)

How do you check for FRP lock on a Huawei phone just curious.

Okay to unlock the bootloader, go into fastboot and plug in the USB to your computer, then by either using SRK tool or adb you need to flash this command: fastboot oem unlock (insert bootloader code) *don't put brackets* if you are unaware of your bootloader code then I cannot help you, however if you do know it, then once you unlocked the bootloader flash system.img and stuff to see if that works for you

That's weird, OEM unlcok was also switched off in developer options for me, yet this still worked, can you tell me exactly what the error code says?

I've tried some command in fastboot mode but there's always an error: Remote: command not allowed.
I can't do anything with fastboot mode

1. Try to force update with Power Button + Min Vol Button + Max Vol Button, liked you said this isn't working try to do the button combination with the phone connect it to the PC; in my case some times dload din't works after I connected the phone to the computer.
2. Other thing, something happend if you turn of the phone and leave Max Vol Button pressed, you should be entering to eRecovery.
3. Remember that sometimes enter in eRecovery mode requires to the phone be turn off otherwise you can't access to Recovery. So if this is the case follow bullet #2 and them #1.
PD: OFC I'm assuming you already have the dload folder with an compatible version of stock ROM on your SDCARD. If you don't have any version tries this one: https://forum.xda-developers.com/p9...dload-file-p9-eva-l09-b136-t3382818?nocache=1
Hope I helped you, I already bricked twice my P9 corrupting System Table Partitions.

If you did the change of Unlock OEM before the bricked in an previous authorized computer you will still have rights for, otherwise new Android Security features is going to rejected the request.

I have a P9 L09, i have unlocked the bootloader, flashed TWRP recovery, and started flashing some roms. I have succesfully flashed a cyanogenmod, and it booted properly, but when it started it asked me for a password which i did not know, so i google searched and found out that it is a common issue and i need to wipe data from recovery. I tryed that but it did not work it says failed, and nothing works in the wipe advanced section, beside system. And also in the custom recovery it says that the internal storage has 0MB ! I was able to put other custom roms on the SDcard and flash them, they booted but every single one asks for the password.. I then tryed to install stock rom with the dload method, but it crashes and 40% , and i tryied the System Recovery option in HiSuite and it says it is not compatible with my device. Any help would be greatly appreciated! Thank you!

Semi working PRA-LX1C432

Hi !
I bought in January the nice P8 Lite 2017 and received a PRA-LX1C432 (dual sim europe no carrier).
It was with Android 7.0 and EMUI 5.0 and i wanted to root it.
I did it well, and was with the firmware PRA-LXA1C432B182 in stock and rooted with the tuto from this thread
https://forum.xda-developers.com/p8...ck-rom-huawei-prague-pra-xxxc432b182-t3727816
and uninstalled TWRP to put back stock recovery.
Later, I wanted to unroot my phone, and that's where things went wrong. I tried to do it with the superSU option and after a hard reset it was working and not rooted, but i'd still have the message "this phone can't be trust" so i tried to relock the bootloader and it did hard reset the phone again and now, i'm stuck with a phone that can send sms or go through the internet with LTE, but can't access fm, camera, google music, nfc is going on and off, calls don't work, etc... In dev options, Allow OEM unlock is greyed and I can't change anything. Phone is recognized by computer and I can acces memory of the phone.
I can hard reset it won't change, i ca also accessFastboot, or recovery or eRecovery, but in Fastboot mode it says "PHONE Unlock FRP Lock" and from my computer i can't do anything : if i try to flash twrp with fastboot command, i have the message "FAILED remote the command is not allowed", if i try to lock/unlock/relock bootloader it says "FAILED remote root type is risk".
Clearly, I don't know what to do. I'm used with rooting/unrooting smartphones from different brands (Samsung, LG, Sony, Huawei...), even though i'm far from being a master, and using Fastboot/ADB commands, but... I don't know.
If someone has any idea, I'm taking. I'm thinking about dload method but, of cooourse, I do NOT have a sdcard, so it's the last thing i would have tried from all i have seen on xda and elsewhere.
Thanks for reading and taking time to answer and help me, and sorry for not perfect english, i'm french but trying my best !

Run a eRecovery restore , it restore the entire smartphone to stock and also lock bootloader. Idk if this can solve your problems but i had ur same problem a days ago and i restored my phone enterely.

TWRP is not installed, and I can't flash it in any way. Fastboot says "FAILED (remote : command not allowed)" if I try flashing recovery or system or anything. It also says "FAILED (remote : root type is risk) if I try to lock/unlock/relock the bootloader.

Ok, I'm actually trying something. I plugged the phone into my computer, and HiSuite told there was an update available for my phone, so I just clicked on it. It's doing right now, I will edit my post after it has finished (for good or bad).
EDIT : Ok, si it did work ! My phone is now on PRA-LX1C432B194, everything is working, not rooted. I relocked the bootloader with Fastboot, the command did work (guess I can root it again if I need now). But I think I'll leave it like that ^^'
Allow OEM unlock isn't greyed anymore, I came back to the original state of my phone but with an update not (yet) available in my country, no more "Device can't be trusted" message. Like if nothing had ever happened (expect it will be written PHONE Relocked).
This phone is really sensitive, haha^^
But as anyway I made it
Thanks anyway for trying to help !

Please Help_After OTA Update Xiaomi Mi A2 died

On Saturday appeared an OTA update to do on my mi A2 but after installed and restarting it died. It does not enter recovery mode and the screen is always on with android one bootscreen logo.
PS: I never flash the phone and i never change anyting in the system of the phone.
The only response that i have in the phone is enter in it Fastboot menu. I read some threads and untill now i cant fix my phone.
I will try to explain what i do:
I've tried using this tool https://forum.xda-developers.com/mi-a2/how-to/mi-a2-toolkit-unlock-bootloader-root-t3834585.
I try option 3 (Unbrick/Revert to Stock/Force update and the program tell me to unlock the bootloader.
When i tried to unlock bootloader by option 1 and then 1, 2 and 3 ( Unlock flashing critical, unlock OEM , unlock flashing ) the programs says: Failed Unlock is not allowed.
Then i try the response 9 to this thread https://forum.xda-developers.com/mi-a2/help/impossible-flashing-xiaomi-mi-a2-t3837565 to try unlocked the bootloader
But i have the same response ( Flashing Unlock is not allowed )
I read and i try but i cant unbrick my phone, someone can help?? Thanks

We are in the same boat buddy, the same thing happened to the phone of my wife.

It *sounds* like the update failed, and normally that would mean it would switch the slot back to the one that was working and boot that.
But you've tried a bunch of options from some tool, I've no idea what it did, as the tool doesn't tell you what commands it's doing.
I'd suggest to go to fastboot and see if you can tell which slot is active, then switch it to the other slot, then do fastboot reboot and cross your fingers

I have the same problem (for other reasons, but exactly the same problem). You can also try "fastboot oem edl", but it did not work for me, so I suppose you have little chance for it to work.
I have been searching and it looks like there are some "deep flash cables" that can make the phone enter edl mode to flash it using mi flash tool. Maybe these could work for us. There is apparently other way to enter edl mode, but it requires opening the phone (that I do not want to do) to short two test points.

I cant enter revorymode only fastboot mode. But when in fastbootmode my connected pc cant even find the phone. Im going to return the phone.

I have the same problem, I have this edl cable but so far no luck.
Do not realy k Ow how to use.

Are you sure it was the OTA update that bricked your phone? That Treble system isn't just there for the kicks, its there to prevent serious issues like these.

I'm stucked on fastboot, I don't want to open my phone. Could anyone help us? I already tried a lot of things, my computer doesn't recognize my mobile when is on fastboot mode. I already tried to install a lot of drivers or try to use differents adbs.

Question Big Problem Need some Help

Hey i spend today a lot of time to tried to fix my bricked Redmi Note 10 5G.
I just wanted to unroot my phone but i did something wrong.
First problem i have is the dm-verity corrupt.
So i read and tried this

And the dm-verity corrupt and keeps hanging on the redmi bootlogo.
So i hope some one have an solution for me and can help me and fix my phone.

Becuase the bootloader is locked again warrenty only the dm-verification message is there.
Do gonna say i updated my phone and now its not booting anymore.
Or do you or maybe some one do have an tutorial program or tool to fix it.

Download ROM for your phone and extract to desktop. Reboot to fastboot and open flashall.bat. it should run firmware through and reflash phone completely. Boot phone and on boot screen keep pressing power so phone can boot and bypass DM Verity error. Once booted reboot into fastboot again and enter fastboot oem cdms. Reboot phone and DM Verity should be gone.

we repeats same anawers continuosly.i dont understand why some users decide to mod their devices, if they dont know how to use Google, and don't understand how to follow the flashing guides step by step. and finally after flashing custom rom, they ask how back to stock

Get what you are saying, think there is at least 8 threads on same topic.

Hey thanks for the answers and the things i could tried to fix my phone.
im not a noob with rooting and flashing android phones before i do flasshong or rooting and the other stuff i always read and check the xda forum before i do.
With other android phones that i had before i made some misstakes before but like a bootloop or something else that the phone not was booting but always i can fix the phone.
So the problem what i had with my Redmi note 10 5G and not one solution that i found on xda or something that maube could fix the problem nothing could fix it.
So i a couple of week ago i went to the reseller and they send it to a repair center.
I think the coudnt also fix it because the did a boardswap.
I think if they cam fix it with a tool or software and reflashing the phone they did.
Now i wait some time before i go rooting or flashing stuff on my phone i hope there will be good twrp so thning go musch easier in the future to fix stuuf like (DM-VERITY Corruption.

twrp is not necessary. fix dm-verity is easy. the are MANY MANY MANY post where is explained how to do. root new phones is dofferent but not complicated. magisk works fine if installed following the latest guides. it's impossible damage mainbord after a root procedure. sure you didnt follow the guides with attention. i have rooted my global phone many times without problems. simply you have made a bad flash of vbmeta or product partition. you made a big mistake, cause this devices can be rooted without brick
