So basically my phone has discharged and after plugging it to charger, it turned on itself and freezed on this screen... I tried to go to fastboot and recovery and holding power button but nothing helped.
U have broken verity. Only fix is to run the tool
Problem is fixed, holding volume up and power button for couple of seconds worked.

Hi,
I've just received my Nexus 4 today.
I tried the phone and it was working great. So, I decided to root the phone.
I installed the drivers, unlocked the bootloader and rebooted the phone without any problem, but I noticed something strange, when I installed the usb drivers, I couldn't browse of transfer files to my phone, I thought it was just a bug and I said I would remove the usb drivers after rooting the phone.
After unlocking the bootloader and rebooting the phone, I powered off my phone, but it doesn't want to boot again.
All I did is unlocking the bootloader, I didn't root or flashed any rom or the supersu yet.
Anyway, after several times of pressing the power button and the volumes button, it booted again into the fastboot, and the first thing I did is re-locking the bootloader in case I can replace my phone if there is any problem with it.
I rebooted it after re-locking the bootloader, and it worked again.
For some reasons I decided to reboot my phone, and I did it while it was plugged to my PC.
Now the same problem happened, it doesn't want to run again. I tried every button combination (Power button for 30 secs) (Power + Volume Up) (Power + Volume Down) (Power + Vol Up + Vol Down). Nothing worked. It's completely dead.
It's not completely turned off because when I plug it to my PC, a new devices appears in the device manager but there is no driver for it.
Also, when I press the power button for 30 seconds while it's plugged to the PC, a red led light appears for few seconds and it disappears again.
I figured out that the problem happens when I reboot the phone while it's plugged to PC.
Now the phone is dead, and doesn't want to boot again.
What should I do? please help.
P.S: The battery was 100% charged when the problem happened.
This case is somewhat similar to mine.. I still havn't found a solution yet ....
Nevermind, I found a solution.
I charged it for 15 minutes, then unplugged the charger and pressed power button + vol up + vol down simultaneously, and it worked.
My battery was fully charged though. So, I don't know why charging the phone solved the problem.

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.
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?

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.
Hello.. i have the same problem here. It keep restart after 2 seconds. When i push the vol up + power button, it goes to recovery mode. Ive done wipe/reset factory n wipe cache. And still i cant switch on my phone.
Huawei Nova Plus MLa L12 restart every 2 seconds..
When it restart too fast, im also can't enter twrp and fastboot..It restart too fast and vol +- can't detect..If anyone have solutions for this problem, please inbox me..Thanks.
Hello i have the same problem, I tried all the combinations of the power button + volume button + and volume button -, but nothing works, I even disassemble the phone and disconnect the battery, then connect the phone to the pc with the cable, but nothing works, are there any other proposals?
same here... any sugest?
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.
