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 appreciate！ 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?

[HELP] Phone won't open the bootloader on Moto G4 Plus

I was flashing the Lineage OS 14.1.2 using the latest TWRP custom recovery. I wiped the necessary partitions excluding the internal storage and i unknowingly hit reboot while the OS was not installed. The phone restarted and got stuck on the "Your device has been unlocked and can't be trusted." screen. I tried to open the bootloader again by holding power down+volume down and it restarted and again got stuck at "Your device has been unlocked and can't be trusted." screen, any help?

Hold the power button down until the screen turns off, and at the INSTANT the screen turns off, begin holding the power button. The phone should boot into fastboot mode.

Not working

It's not working still stuck on the same page
EDIT: It worked did you mean hold Volume Down?

Good to know that it did work. Yeah, I meant to hold volume down.
Also, for future reference, when you force shut down the Moto G4, the first shutdown starts an autoreboot. So, you don't even need to continue holding the power button- you can release the power button after the screen turns off and just hold down the Volume Down button.

With this options is nothappening nathing just again is going to restart it every 2 seconds. Vol up + vol down + pwer button on more of 15 sec is going phone on power off.
I made relock on bootloader because I wanted to take it away waring: your phone is unlocked an can't be trusted ....

well...youve learn the lesson the hard way...you just cant get rid of that nag screen...
only thing left now ( i think) is to ... send it to huawei for ressussitation...
cuz at that point i dont think theres a method after loosing ADB access

Hi! Have you repaired your phone? If not, the way is easy. You need plug USB cable and hold Vol-. You will enter bootloader. You should again unlock bootloader with your unlock code. After that bootloop is gone.
It could be that phone won't enter bootloader. In that case you should power off phone. Possible needed to disassembly and eject battery cable. After that plug USB cable and hold Vol-.

I have same problem too, and I bought the phone from china, can not return back, any solution ?

Hi...what have you tried till now ?
try hold power off button for around 30 seconds...
then try VOL-DOWN+ Power while plugged to pc....

i had same problem today. Thought i have ruined my phone. But trying to rebooting the phone while using variuos options with power volume up and down accidentally succeeded. It was in my case holding power and volume button until stopped appearing reload every 2 sec, then i have released the power button while kept holding volume up button. And lucky i booted in to Huawei erecovery mode. From there I have booted my Huawei Nowa phone in to a normal boot. Hope it helps somebody.

mate 9 was bricked, any help?

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.

LG G6 (H870) stuck on boot screen after twrp flash

Hey everyone,
so here's my situation:
I unlocked the bootloader for my G6
I activated USB debugging and OEM unlock in developer options
I then flashed TWRP 3.4.0-1
Now the phone is stuck on the boot screen, when I hard reset (power button + volume down, then pressing power button again when G6 logo appears, then selecting "factory reset" and "yes" twice) the phone does not boot into TWRP but instead goes to the boot logo again and nothing happens. I tried leaving it for a while and it stayed like this until the battery ran out. When I plug it in, it starts the same procedure immediately. When I connect it to my pc, I cannot manage to flash anything because I can't boot into bootloader because the phone is not detected (my pc doesn't play the usb plug-in/unplug sound).
So my question really is: Did I kill my G6 since I am unable to flash anything or is there still an option to get bootloader running again? And yes, I did try the unbrick method under https://forum.xda-developers.com/lg-g6/how-to/lg-g6-unbrick-method-t3935924 but I get stuck at the point where you need to click "download" because my phone is not detected. I also heard about the method of shorting the pins beneath the flash but I don't know how to do that...
Any help is appreciated.

Hi,
I had the same problem and finally solved it by using the release of TWRP found here : https://forum.xda-developers.com/t/recovery-twrp-3-1-x-stable-official.3627595/
After flashing TWRP I followed those restarting steps :
Hold vol down + power for 10 seconds and your phone will power off.
Hold vol down + power / release power when the LG logo appears and then immediately hold power until the Factory Menu start
Menu select Yes
Confirm Yes
TWRP boots
Hope this will help
Edit : A more recent version of TWRP compatible with LG G6 is available here : https://forum.xda-developers.com/t/recovery-twrp-v3-2-3-1-for-h870-h872-us997-unofficial.3828254/
