P9 plus bootloop

Hi to all,
my P9 PLUS bootloop on start after upgrade after UPDATE.APP with c432 noougat:
is bootloader unlocked, but when try to restore the rom(or another rom) its says that rom is not compatible.
I try to flash trwp, but don't works, only have the possibility to enter in fastboot mode.
There's a way to fully restored? or its possible install a mod rom?
it was originally L09c155, debranded to c432.
thanks in advance:fingers-crossed:

P9 Plus is traped in a bootloop
Hey it thems we both have the same problem: My new P9 + is also traped in a bootloop and is obviously locked. Phone locked, FRP Lock.
Huawei does not want to help because I have no HuaweiID and the product ID can no longer read.
Would be nice if anybody can help me or tell me how to proceed. I have read the entire forum here, but no solution for me, because I can not write the flash without usb-debugging. What i have done:
I wanted the old version VIE-L29C636B130 update to Nougat with EMUI5.0.
I have used the firmware finder. FF worked quite well, just not to nougat, as I wanted.
I have used the update function via SD card successful to VIE-L29C636B202.
When I started the B362, this update has hung up, has not gone through and then the bootmode has been running and showing that Android can not start. Then I tried the previous version again and this didn’t work also no more to install.
Now the phone is landed in the bootloop and I can see the phone is locked. All what I can do now is start the recovery modus (Vol- and Power Button). But there is no restore version. Phone locked, FRP Lock.
Can anybody help please ? Is root or unlock modus a solution to write the flash ?

Only solution is to use Dc Phoenix, it's a paid Service but it should unbrick your phone.
It use a backdoor solution to flash even if the frp and bootloader is locked.

Thank you, I thought about dc Phoenix, but i was not sure if this service is serious.
You mean my phone is bricked?
I thought about sending the phone back to Huawei. Waranty ?

Cant receive OTAs

Hello
The story goes like this: When the android 9 came out i used a hack to get it more quickly, the one which you trick the phone (with a vpn) that you are located in another country (Netherlands) .
Since then i can get otas only if i repeat the process and trick the phone i am in Netherlands. This is a pain since i am located in Greece. Can someone help me to undo this?
Thnks

Unlock bootloader and reflash the official ROM with mi flash.
Even you don't want root your phone I still recommend unlocking bootloader just in case some ota goes bad

Thank you very much for help. I have read both but unfortunately i can not UNLOCK my bootloader… when i was trying to unlock the bootloader through MI UNLOCK, it says "Current account is not bound to this device". Otherwise if this was succesful and i could unlock it, then it would be easy i believe.

Since you locked the boot loader, you'd have to flash (with fastboot) using the same flavor of miui which was installed. (example: chinese or eu variation), otherwise you won't be able to boot.

Yes, that i understood… There was EU variation with unlocked bootloader, which i do not know why, but okay…
But now i can not unlock it, it says, when i try to unlock it though fastboot with mi unlock, it says "Current acount is not bound to this device, ADD your acount and device in MIUI"s setting > developer options> mi unlock status.. but obviously i can not do it since i can not turn on my phone, its stuck on recovery mode.

I can help you
First of all you need chinese mi assistant
Second you need try three versions of roms(eeu , china , global) but im pretty sure that your phone is chinese version that bought from gray market and they unlock bootloader to install global rom
After you download these tell me, i guide you
Be sure download recovery rom (not fastboot)
It has .zip extension not tgz

If you know how to sideload the rom then everything is become okay dont worry
After successful debrick you must bound you mi account to your phone and wait for bl unlock then reflash with mi flash tool and global rom
AND DONT LOCK YOUR BOOTLOADER AGAIN

Yes, unfortunately i do not know how to sidload the rom... But when i have Chinese rom downloaded then what do i do with that? I connect the phone through mi assistant and there it can be flashed?

I had the same thing happen. You need to force a firmware flash ?
I had someone on xda recommend an excellent recovery tool.
It's called 'miflashpro'. It can be hard to find the English version. I did eventually but actually unbricked my Mi9 with the Italian version.
99% chance your cell can be fixed this way

bricked too
I'm having the same problem here, after wipe in twrp mode my phone restart and i'm blocked on bootloader screen.

I did the same thing with a Mi CC9 relocked the bootloader by mistake thinking it was like any other android phone. Did you have a Xiaomi account associated with the phone and signed into after enabling oem unlock in developer options.
If tha'ts the case you can use https://en.miui.com/unlock/ tool from where but it checks your phone number to see whether its associated with mi unlock.
Otherwise you will have to use EDL method which involves disassembling back of phone and shorting out two pins to initialize EDL data transfer but you need a EDL associated account this (belief xiaomi has revoked everyone access to these)

Hello all members.I had same problem and I open this phone with suport from youtube .I try clean some connector and worming cpu and motherboard. After change the battery with new.

why do you want to use Mi unlock,?

Well if you can find your device in minimal adb you are good to go, reboot your device into fastboot,run the command "fastboot devices" and check if your device shows

Don't use mi unlock to update your ROM. You need to install TWRP and update it using recovery. Latest updates are all twrp updates, not fastboot.
Do a search on this forum 9r go to the Xiaomi EU forum for info on the update and how 5o install twrp

Question XIAOMI Mi 11 ULTRA BRICKED

Hi

XIAOMI MI 11 PRO/ULTRA BRICKED
hello guys someone can help me please¡¡ i flash with miflash tool the last EEA rom and lock the bootloader and now the phone says :this miui version can't be installed on this device i try to flash the last china , global and mi flash tool make...
forum.xda-developers.com

Never lock the bootloader when flashing a non original ROM. You may now need to find someone who can perform an edl level flash. Just look at other posts, they do mention who to contact but it will cost a few dollars.

Your case is more easy than was mine. Just reflash the original ROM, unlock, and flash the global.

Cant flash original ? how did you flash it ?
I just found a guy fixed it in EDL mode remotely (Paid service )

are you sure you can't flash?
You said your phone can't boot, get into fastboot, download the oficial fastbook rom to your smart, and just re-flash using the cable

its locked bootloader !
i relocked by mistake .. and mi account is not mine so i cant unlock again
I wont send this post if i have unlocked one

EDL flash then I'm afraid

Same problem here.
Anyone have a contact who can help me, $$.
Thank you

Edl flashing is easy (if we are talking about the same thing), you just need an original rom and the software. But yeah, not sure if that exists for the Ultra out there..
Software is MiFlash or something like that IIRC.

Has your phone fixed?

Yes I paid someone and with the appropriate tools unbricked my mi 11 ultra
But I do not have the contact anymore.
