mate 9 was bricked, any help? - Huawei Mate 9 Guides, News, & Discussion

before brick, it had being prompted for a while to upgrade the system software, I always tab later to postpone it. but yesterday accidentally hit the "upgrade now" then it was bricked after the phone was rebooted.
the screen stayed at the huawei logo and powered by Android at the bottom. I am able to push/hold the power button to power it off, but not able to power it up by any buttons or combination. it will automatically turn on (randomly) and stayed at the huawei logo for ever.
when the phone is on at the Huawei logo, connecting it to PC but either "adb devices -l" or "fastboot devices" shows nothing, no devices.
could anyone please share some light?
Thanks

Did you ever unlock bootloader? Could you enter fastboot mode? (hold volume - and power button). Or eRecovery (plug usb cable, hold volume + and power, until Huawei logo appear, release power button)?

unfortunately, I didn't unlock bootloader, so I can't enter fastboot mode actually. as I mention in the original post, I can only power it off when it's at the Huawei logo, but not able to power it on with any combination, it will randomly power itself on.

You have a corrupted /data partition, happened to me one day, on another huawei device (p9lite). You should, I said should, be able to reboot to huawei e-recovery, using power+volume up, release power after huawei logo shows up. Unfortunately you have to arm yourself with lot of patience and try to use an "unbrick guide" from another device. I'll try to find any info I can for you, but in the mean time you should look as well.
PS:/ I didn't even tried to install anything custom on this mate9, since it;s an expensive phone for me and I cannot afford to brick it up.

You can't update modified firmware i must be stock for OTAs. If vol down + power key don't work, try this method (make sure battery is not drained out) - take your phone while it's off, press and hold vol down and vol up buttons together and plug it into computer via USB - it should boot in fastboot mode.

P9 lite cannot boot up only show device is booting

Hi Masters,
Need your advice here.
My p9 lite cannot boot up and only shows your device is booting now screen.
I cannot power off even force power off, and there is no responding whatever key combinations i pushed.
The step taken to this error is I did unlock my p9 lite and tried to flash twrp by following the guide, then I cannot enter fastboot mode and recovery mode after that.
I tried take out the battery and let the phone disconnect with power supply, after i put back the battery, i push the power key it still shows same screen as your device is booting now.
Any idea how to resolve this? I assume some fatal error with the motherboard, but i can say nothing after i unlock the phone.
Your suggestion and advice are much appreciateļ¼ thank you!
I had the same problem,what I did was force power off by holding power button for ,well idk how long but until device booted down,then I held volume down and connected it to pc,so it enters fastboot,but you have to do it fast,as it will reboot once its turned off.Then I tried various twrps,revolution recovery etc,and the only one that worked was meticulus twrp.I know you said you cant force power off,but try holding power key long
Once you hold the power off button, the phone will never power off, instead, the phone will reboot and bring you to the error page "your device is booting now" and stuck there. I tried to push the power up or power down button before i see huawei logo, but it will show me the same page.
Yes,when you hold power off phone will reboot,and you have to be fast with volume down and cable.Pre-plug the cable it computer ,bring it near phone,power off and before it boots plug it in while holding volume-
thank you for your suggestion. I tried many times, no matter how quickly i am, I only able to see the device booting page. I have mentioned one point above, i did take out the battery, and i see the error screen after i put back the battery, so i assume the problem with motherboard.
How many of you did return the faulty and unlocked phone to service centre then get "free" services?

I think I bricked my P10 Lite. Need help please

I was messing with my P10 Lite and I accidentally wiped the Vendor partition (not sure if I wiped anything else) with TWRP. After the phone rebooted it said something about a critical error during boot and went into erecovery. It gave me two options( I don't remember the second one) and I chose factory reset. It started doing it's thing but I guess something went wrong because it wasn't able to boot and it started to bootloop.
I managed to get into fastboot once. The bootloader and FRP should be unlocked but I am not sure as I think I semi accidentally used the command to relock the bootloader in the hopes of it doing the automatic low level factory reset. After that restart, the phone wanted to boot up but after the Huawei logo it went into the EMUI logo which I've shown in the pictures. Now I can't use any button combination and can't enter any menu. I also can't shut down the phone as it bootloops into the EMUI logo after I press the power button. I opened the phone and turned it off by detaching the battery cable but after holding the power down key and plugging the usb cable into the phone it still boots into the EMUI logo right after the Huawei logo.
I guess not being able to enter fastboot is the major issue and after hours of googling I am yet to find a solution.
Edit: I am a newb!
Please help!
Why did you delete the vendor partition, you could try plugging the phone into your computer and checking if you can do anything with fastboot while it's showing emui logo?

Dload method. Put sd card in other phone or some card readers and put appropriate files.

I've already tried that. I've placed the appropriate files into my SDcard but I can't use any button commands including volume up+down+power. When I press them my device just boots into the EMUI logo and nothing happens.
Edit: It boots into the EMUI logo even if I only press the power button. Pressing volume down + usb also boots me into the EMUI logo

Power OFF the phone.
Press and Hold VOL Down and connect the phone to PC via USB cable. The phone should boot into Bootloader (fastboot mode). Does this method work?
or try this:
Press and Hold VOL Up and connect the phone to PC via USB cable. The phone should boot into eRecovey mode and then then select "Download latest stock rom and install".

Ok, it seems like not all is lost about my phone. I managed to get into fastboot. In my situation, pressing volume down + usb cable while the battery was plugged into the phone did not work. That was before I opened up my phone's case and disconnected the battery cable.
As I mentioned before, I had opened my phone and disconnected the battery cable because that was the only way to shut it off.
What I did after I disconnected the battery cable was the following:
1 - Hold volume down and don't release it
2 - Plug in USB
3 - Plug in the battery cable into the phone's mobo.
That booted me into fastboot. Right now, the phone says my bootloader in unlocked and my FRP is locked. What would be the best way to flash the new stock OS on my phone?

I have downloaded THIS and THIS for the new OS but by talking with Alexxxx1 in THIS discussion I learnt that Huawei has implemented a security patch in their latest update, which I've most likely installed, that prevents you from rolling back your OS version. That means I need to install the .386 version, which should be the last if I am not wrong, instead of the .378 correct? Though I heavily dislike patches like this I guess I can't do anything about that...

No access to recovery, fastboot not listing device

Hi all,
The device I have is currently stuck on the Huawei boot screen, and it is unable to turn off as long as the battery has enough charge. Long pressing the power button just reboots the device back to the Huawei screen.
I was able to boot to the erecovery screen, or the HiSuite screen using both Vol+ & power or Vol- & power before. But since last night, I cannot do this anymore. No matter which combination I use, the phone simply reboots to the Huawei screen.
Connecting it to a pc also does not make it listed with either fastboot or adb, so I'm kind of worried that my device is bricked beyond repair.
Do any of you have ideas or advice regarding this situation?
Cheers,
Evert
Connect the cable from your phone to pc , hold the power button and volume down until it show fastboot mode

Help! Stuck on black screen and cannot get to fastboot

I tried unrooting my 6T and something went wrong. Now when it boots it shows the bootloader unlocked warning then goes to black screen and stops. It will randomly vibrate when I press the screen or the power button. My computer doesn't recognize it and I can't even seem to be able to turn it off completely. The only thing I can get it to do is reboot by pressing and holding the power and volume up buttons.
Any advice on how I can force it into fastboot or get my computer to recognize it so I can working on it?

Keep pressing simultaneously volume up , volume down and power button all three of them until you get the fastboot screen.
It maybe takes a while...

like the first answer:
hold vol up, vol down and power butten as long as the phone boots into fastboot mode and flash fastboot Rom OR
hold vol up and vol down for about 5-6 seconds, and plug your phone to your computer. if it gets recognized (with typical sound of windows) try msm tool. And be sure you have the qualcomm driver installed.
