try a cold boot from linux to get you back into your rom (volume down + power, do not press volume up when the notification appears and let it boot into the cold boot menu)

thanks for posting, but when hold power + vol down it goes on a menu and then it goes on bootloop
twrp has terminal emulator included i think, why not try using the commands in the link i posted to see if it works
I've solved the problem. I've hold power and vol down and then I 've hold power and vol up. So my pc recognized my device and Apx mode worked!! Then I've flashed asus stock rom with easy flasher.
ps: forgive my wrong english

No recovery mode, no download mode, but works ok

Hi, my LG G2 works just fine, BUT it won't boot into download mode (vol up + usb cable plug), nor into recovery mode (power + vol down, and again after logo). In first case it just shows the battery charging screen, in second it keeps rebooting as long as I hold power button. Once I release it the phone just boot up normally.
I have vanilla Android 4.4.2, buttons works as intended once system is up.
I have tried turning USB debugging off and on, no changes.
Any ideas? Thanks in advance for all the replies!
EDIT It's the D802 version.

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.

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?

The usb cabel has to be connected in the phone before u try fastboot mode.
Have the cable connected, hold power until it turns of, then fast hold power + volume down to enter fastboot mode.
Then u can use Dc Phoenix to unbrick your phone.

Here’s how to enter Safe Mode on a Galaxy S10 smartphone:
Shut down your Galaxy S10 smartphone
Hold the Power button key and release it when the SAMSUNG logo appears on the display
Right afterward, press and hold the Volume Down button
Hold the Volume Down button until the device boots up, and the Safe Mode text appears in the bottom left corner

Put it in download mode. Hold bixby, volume up and power, plug in type c connector, and then usb to pc. You should be in download mode now
