The power button and the volume buttons work perfectly fine when the device is unlocked, but once the device is locked, my power button and volume button stop working. I can't get into boot loader either because the power button won't work in boot loader either. I tried using rom manager to flash CM7 twice and flashed miui once, still no solution
A couple things you could try. I'll throw out this first one just to cover all the bases. Sometimes a screen won't power up every time with the power button and what has helped people is to turn on screen-on animation. This is likely not your issue.
The other option is to do a complete wipe several times. And i don't mean the generic wipe, i mean formatting boot, system, cache, data all independently several times. If you having trouble getting into recovery, you should be able to when you are on your home screen and if you hold the power button to reboot. depending on your current ROM you should have an option to boot to recovery.
I'd like to make sure doing that complete wipe a stupid amount of time doesn't correct it before you start trying other things.

Well, I can't really get to the wipe screen because when I am on the boot loader screen my power button doesn't work either. I can't select anything to do ):. Also I've noticed that my power button was previously working (every now and then) but since I ref lashed this new rom, it hasn't been working at all. And my volume buttons only work when the screen is on

here you go:
from root: /system/usr/keylayout and look for keypad.kl I believe. From here you can edit different keys/buttons to WAKE or WAKE_DROPPED. Save it and delete the backup file, reboot and this should do the trick.

Well Hello there, my name is poszy and i am having a very difficult experience.
So about a week ago i rooted my Acer A100 because i wanted cynogenmod, (i was running stock ICS)Long story short i bricked my tablet because CWM froze while i was wiping my tablet.
i did all of the following
1.) Rooted Tablet
2.) unlocked bootloader
3.) installed clockwork
All of these steps were done with the methods found here, Maybe it bricked because i was on Stock.
Anyways, i was lucky enough that my tablet only bricked to the point where it only looped during the android logo.
I am able to access the bootloader, but as soon as i tried to go back to ICS stock (because that was the only rom i could go back to and try to bring my tab back to life) that locked the bootloader. so now i have the stock bootloader. Everytime i try and flash a stock ICS update.zip it does not go past the android logo.
So i tried to flash the Honeycomb stock Acer_A100_1.014.08_COM_GEN1 Via stock recovery, and it all flashes well but for some reason it keeps asking me for a password.
i obtained the Acer_A100_1.014.08_COM_GEN1 from this thread http://forum.xda-developers.com/showthread.php?t=1307046
Stock Recovery seems to be working fine because when i power on my tab it loads into honeycomb but i cant get past the first screen because it keeps asking me for a password. :crying:
i have tried to do a hard reset with the pinhole but that does not do anything. Every Honeycomb stock rom i try to recover from always tells me to enter a password and every ICS rom i try to flash with the default recovery will not boot past the android logo.
on honeycomb i cannot do anything, i cant mount storage or access app drawer or anything because the pinlock dosent allow me to.
Can someone please help me and tell me what im doing wrong?
i was fortunate enough to make a nandroid of my ICS stock rom, but thats no use with a stock recovery right?
Since you flashed a stock rom, you should have a stock recovery, locked bootloader and unrooted. So you should be good to go, to just do a normal factory reset. To get rid of the pin lock.
-----------------------------
-Press and hold the Volume up button. Which is located farthest from the corner.
-While still holding the Volume up button, press and hold the Power button for 3 seconds and then immediately release it. Continue holding the Volume up button.
-The tablet will vibrate in approximately 1-2 seconds after you release the power button, once you feel or hear this vibration, slide the screen lock switch on and off repeatedly while continuing to hold the Volume up button.
-As soon as the Erasing Userdata... message appears in the upper left corner of the screen, release the Volume up button and stop sliding the screen lock switch. You should then also see the Erasing Cache... message below that as proof that your device is being wiped.
Many thanks

HOOOPLAA!!!! :highfive: thanks alot that worked perfectly! my tab is back to 3.2.1. Thanks alot!!
Hi Everyone! I'm pretty new to Android stuff in general, and it looks like I soft-bricked my phone while trying to install a custom kernel.
Currently, my phone is running the latest beta of PA (pa_m8-4.6-BETA1-20140902).
I was trying to install custom kernel franco.kernel. Quick googling told me this is possible and the process was to boot into recovery (I'm using TWRP), make a backup, clear cache and dalvik cache, reboot into bootloader and then use fastboot to flash the new boot.img. Was this process correct, or was I already destined for failure?
After doing that whole process, the phone no longer boots properly. When powering on the phone, I see the initial HTC screen popup, and then the screen goes black. This stays this way forever unless I hold power + vol up, which will just restart the phone and the same thing happens. No other keys or key combinations do anything. Holding power or power + vol down does nothing. Holding power + both volume is the same as holding power + vol up. I have also tried holding the power button while holding the phone under a bright light; this has had no effect.
Unfortunately, I can't take a video of this behavior, however it appears this youtube video shows the same behavior:
CPCVecKSPAA (sorry can't post links because I'm new)
The only differences between my behavior and the youtube video are:
1. I am using AT&T instead of international version
2. At the initial screen, I see the red warning text.
Currently, my plan is to wait for the battery to die and then plug it in and try to boot into recovery with power + vol down. Does anyone know anything else worth trying?
Thanks !
Just refresh the rom... That will restore the PA kernel.
I was able to get my phone into bootloader via the following:
1. Plug phone into PC.
2. Press power + vol up + vol down.
3. As soon as charge LED turns off, release vol up.
Once I was in bootloader, I got my phone working by going into recovery and then restoring my backup.

I took my phone in for a cracked screen and when I got it home I found out the volume up was not working. So I booted into recovery thinking I could check in recovery to see if it was a software or hardware issue, but the volume up did not work there. So I rebooted and now my GPE edition rom is stuck at the spinning dots. When I go back to the bootloader I cannot select recovery. My volume down button make the selection go up, my volume up button does not work and for some reason even though I can reboot with the power button, I cannot select with it. Is there any other tricks to wipe and reinstall?
ADB does not return a device list.

I had the exact same problem, but opposite. Vol down didn't work. Bootloader problems were the same.
Your issue is that you vol up is stuck.
The way i fixed it was to pull off the volume rocker and put it back on my own. I DO NOT suggest you do this.
When you took it for repairs, the reassembled it incorrectly. Take it back and have them fix it.
hi,i wiped my phone using twrp and ended up wiping everything including system
so my phone is stuck on the htc pop-up screen
can't even shut it down or open bootloader

Hold power and vol up buttons for a while (maybe 10 seconds or more) until the phone reboots. Once it reboots (screen black), immediately let go of those buttons, and hold the vol down rocker, don't let go of vol down until the bootloader screen comes up. If the HTC logo screen comes up again, just repeat the process, as you probably just started pressing vol down too late, or let go of it too early.
Once into bootloader, adb push a known good ROM to the phone (or put a ROM removable SD). Install the ROM in TWRP.
And let this be the lesson to NEVER wipe anything unless you know exactly what it means and what the result will be. Then double check and triple check what you have selected before confirming the wipe.
Those TWRP options are under "Advanced Wipe" for good reason. And the TWRP wipe screen also says for the default wipe that "Most of the time this is the only wipe that you need". Again, it says for for good reason.
Hi,
I have a bootloop issue (I was using LOS official and it crashed when I answered a call) and when I try booting in recovery mode it just starts normally.
I do the Power + Vol down until I see the LG logo then release both for a short time and hold them again but it starts the LOS bootanimation..
What I am doing wrong ?

The G4 has a really stupid way of entering the recovery. I couldn't get in for a while too. Try again making sure you are actually pressing the buttons together at the same time. That means having just one click. They have to be clicked down at the exact same time.
Also, the instructions you've seen (first Google result) may not be the best. This is what I do WITH a custom recovery (TWRP).
1. Power off completely
2. Holding power and volume down at the exact same time until the lg logo appears.
3. Continue holding the volume down button but release the power button for a second.
4. Press and hold power and volume down again.
5. When asked if you want to wipe the device, select yes. This won't wipe the device but will take you to TWRP (if you installed it). Otherwise, it wipes the device.

Same Issue here, I was on Genisys opened whatsapp cuause I had a new message and phone rebooted.
after that it just stay on LG logo.
I followed your steps and got to the option of factory reset but after I hit ok with the power button phone just reboots back to the LG logo.
I think mine is the genuine bootloop issue.

Hi guys, today I've managed to brick my G4 so it doesnt boot neither to recovery nor fastboot nor download mode. It just loops the LG logo as you can see here https://www.youtube.com/watch?v=9gm0dh6bLp4
Any ideas how to recover?
Thank you

If you don't remember doing anything that might have caused this, then it may be the LG G4 bootloop bug.
I'd put the phone in a zip lock back, in the freezer overnight and then back up all my data as quickly as possible. You're phone may be dead.

I'm sure I've bricked it while flashing LOS (regular dirty flash of new weekly like i do nearly every week), this time just went something wrong...
As far as I can tell from some YT videos my reboot pattern is different from regular G4 bootloop
Thx for your replies, I managed to revive my phone after whole day of tinkering. Had to overcome some issues so I've posted the solution: https://forum.xda-developers.com/showpost.php?p=73539738&postcount=1

Hmm, wait, ok. I did it finally, you just need to press them simultaneously and then when LG logo appears just release the power button for literally 1 second and then press and continue to hold both of buttons. That's it.

This actually worked!!!!....The 1 Second is crucial in the process, I did it on my first try after reading post
I did the procedure but it went to a page that said clear your phone or not! Just it, and there is no option to clean cache partition or any other
