[Q] Hard recovery reboot not working (Vup+Vdown+Pow)

Is there some secret to the Volume UP + Volume DOWN + Power hard key combo? I've pressed it hundreds of times with different timings and can't get into the bootloader. Tips?
Also, the power key takes sooooo long to turn this thing on. At first I thought it was doa. Thought that was interesting...

There really isn't any secret method. Just make sure the unit is powered off then hold the power button and vol down button until you see the Android robot and you can through the options using the vol up and down keys.

Wow, I did Power + Vol Down and it worked immediately. I know I've been reading all over that its both Vol UP and Vold Down. Arggggh. :silly:
And Thanks :laugh:

[Help] Phone wont turn on after low battery

I have been using my LG Optimus G for about 6 months now and everything was working fine, untill yesterday.
My phone ran out of battery and i left it over night to recharge. In the morning when i tried to turn it on
the screen just stayed black and it wouldnt start. The only thing i can get out of it is when its plugged in
and i hold the power button for about 10-15 seconds the led light shines red for about 7 seconds.
Other than that i cant do anything with it, cant even get the lg logo or the vibration from the boot.
Tried a hard reset-didnt work
Ive looked a little bit online but i couldnt find any problems like this and i really dont want to buy a anew phone
since ill have to save up for like 6 months
Please help
Thank you in advance
PS: Sucks to have this as my first post

Had also that problem. For me it helped to press the power button as long as it takes untill phone goes on even if it takes some minutes. But if it not help, try to boot in bootloader(volume up+power+home). In Bootloader mode press 2times volume down and power button to get to your recovery. If getting succesfully to recovery make a full wipe and install your rom.

Held the power for 2 min and no effect. And for the second point, what do you mean by Vol up+ Power+Home, because my phone doesent have a physical home button.

Press volume up+ home+ power (all together). Home button which you usualy use all the time, yes that button in the mid, i know its not really pressing so hold your finger on it. After that you will come to the Bootloder mode, in there you should press 2x volume down and then power, this will bring you to your recovery.

Wont work . This looks more like a hardware malfunction.

It seems the battery is not charging. If your phone is not modified in anyway,send it to warranty. If you're rooted and have a custom rom,go to a gsm service,at least to make it turn on. If they do that,flash stock and up to warranty with it.

Did you make a nandroid backup before u flashed viper one? If u did enter recovery by rebooting holding down vol down and restore your backup. Or flash your carriers stock firmware. Check the back to stock thread for info on that.
If that doesn't work it's a hardware issue and you should check your warranty and get a replacement.

Thank you guys for the help and for everyone coming together to come up with solution it is deeply appropriated my M8 was finally able to boot it up I plugged phone on the charger and directly to the power outlet on the wall and hold the volume up + volume down + power bottom all 3 keys at same time for 20 minutes and released all key at the same and left phone on charger over night for 24hrs and phone was able to boot up

I think you only need to hold Vol Up + Power for a few seconds and it should reboot.
Mine did the same thing once and that's how I got it to restart.

True. Power + Vol Up is a reboot, basically a simulated battery pull (for phones that have a removable battery.
Power + Vol Down boots into bootloader.
Power + Vol Up + Vol Down is not any button combo on this device, that I know of. This is perhaps a button combo for another device? Care should be taken to only do known button combos. Although I don't think there is any "harmful" button combo on the M8; on my old One X (EVITA) folks would mistakenly do Power + Vol Up to go into bootloader (correct combo is Power+ Vol down) which erased the ROM and sent the phone into Qualcomm download mode, which would probably give you a heart attack!

HTC One M8 stuck in boot loop, won't power off

Hey, so I was messing around with my phone and using TWRP, I deleted the original ROM and then, having forgotten that I'd deleted the ROM, tried to reboot the phone. My phone is now stuck on the HTC splash screen (which at the bottom has the text "This build is for development purposes only...") and won't turn off, despite me holding the power button for probably 1+ minutes. I'm planning to wait until the battery dies, then once I can boot again try to get into TWRP by holding the power button and volume down. Does anyone know if there's a way I can get to TWRP without having to wait until the battery dies (my phone is at full charge), or whether this will not work and I should try something else?
Thanks in advance!

Press and hold power & volume up buttons until the screen turn black then release both buttons and quickly press & hold volume down button only. This will get you to hboot

Question Black screen but still working. How to shutdown phone

Hi,
My Pixel 6 Pro screen went black, but I can still hear and feel that the phone is working. I used the volume up + power button to reboot it and now I touch the phone and I feel it vibrate as it's registering the touches. I also see at the bottom of the screen some white stripes flashing. It seems that the screen is damaged and I need a replacement screen.
Now my issue is that I can't seem to turn it off. As the screen is black, the only way to shut it down would be with hardware keys. But up until now, I haven't been able to figure out a way to turn the phone off.
Does anyone know how I can turn of the phone?
To replace the screen, obviously I need to turn it off first...

Usually long pressing the power button, but it may be different. As long as it gets fixed within a month or so it you can let it discharge until it auto shuts down. If more than a year old replacing the battery when repaired is a good idea anyway...

I tried long pressing the power button with no luck.
I tried volume down + power button for 20 seconds, didn't work either.
I tried volume up + power button for 20 seconds, this I think reboots the phone.

Power button only might take 20 or so seconds.
Otherwise just like it sit until repaired.

Power button + vol up + vol down. Keep holding down once you feel the phone vibrate. Takes you to the bootloader screen

The battery died.. so that's good!
Thanks anyways
