[Q} Power/lock button stops working - LG Optimus Black

Well I've currently got zeus 3.2N installed, and the power button has become very temperamental. Sometimes it just will stop working and the phone won't lock, nor will power options come up. When the phone then locks on its own, I can't unlock it (the only way is to plug it in to a charger). Once plugged into the charger, it works fine for a bit but then the same thing happens and I have to unplug it to unlock it.
I've tried performing a fresh install several times, and have tried 3.0N aswell with no luck. I tried going into terminal and getting a log, but it told me it did not exist so I'm not sure if I'm doing it right.
Any suggestions?
EDIT: Nevermind, I just flashed back to stock rom, and I'm having the same problem. Must be a hardware issue...

Lost Button & Keyboard Functionality

Started experiencing a strange issue with my tilt today..
When I soft reset it loads the Today screen, and then attempts to search for the contact 'wszx' (these keys are located next to each other). After this I can navigate the phone just fine using the touch screen, but the only buttons that work are the directional and center buttons located on the front of the phone, and the arrow keys on the keyboard. I cannot type at all using the keyboard, and pressing any of the other buttons does nothing (except the directional/center/Power). I also cannot Hard reset because the two soft-keys do absolutely nothing. I've hard reset in the past but it no longer works.
So am I SOL? I think I've tried everything.. and now I have a custom rom, etc on the phone and I have no way of getting it back to factory rom without the ability to hard reset.
Thanks for any help.

Sounds like a hardware issue or simply a bad flash. Have you attempted to reflash the rom? Which rom are you using?
Well...
It wasn't working again this morning, but suddenly - out of nowhere - began to work properly. I'm stumped. If I ever figure out the exact issue I'll be sure to post back.
Thanks
Greetings,
I have same problem on my tytn...
Sometimes it suddenly starts working fine, but shortly it breaks again.
I have tried hard-reseting while it was working, but didnt help.
I think the problem appeared after charging my phone with a motorola v3 charger, so maybe it damaged my phone with over-voltage or something...
Anyway, if someone can suggest something i would be very grateful!
Hi I have exactly the same symptoms with my HTC Tytn II...when you power it on it starts typing letters (in my case CEDF). If the recording button is active it will start recording too. This happened suddenly and I haven't used any other charging apart from the usb and wall socket charger supplied with it.
All buttons (except front center key) and keyboard do not work. Any suggestions would be appreciated very much. This phone is only 8 months old.
Hi,
my Kaiser with dutty's WM6.1WWE ROM did the same this morning Yes I disabled the button 6 and stopped the voice recordings but all the hardware keys but few in the center of the keyboard are not responding. So I cant make or receive calls without taking the stylus out and touching the screen soft buttons andd that's pin in the ... while I am driving. I am using this ROM for almost a year now and I am extremely hapy (up to now) with its performance. When it all happened there were no activities on the phone - I woke up from a SMS notification (Yes I did receive an SMS from my bank) followed by repeting Voice Recordings. Any help will be highly appresiated! Thanks in advance!
keyboard problem
I am experiencing a similar problem with my stock tilt my keyboard does work however none of the text appears on the screen. I have tried hard reset and everything else I could think of, short of a clear storage reload. I would appreciate any help or suggestions from some of you more experienced users.
Bisonwill
anyone ever figure this problem out? im having the same thing happen now.
Same here
I've had it for a couple of weeks now.
I'm running WM6.1 from HTC (rom ver.3.29.422.1 from 2009-01-12) so nothing fancy here.
I even ordered and replaced the D-Pad and I replaced the keyboard (just the sticky part though). I totaly dismantled the phone and didn't find any issues with the cables.
Any ideas would be highly appreciated
Join the club!
This is crazy. My problem is exactly the same. I re-romed to the latest phoenix and it did not change a thing.
Help!
help....
any body here found a solution for the keypad/keyboard yet??? i have the same problem as you guys... any idea, thanks so much...
i have the same problem And there is something else. My Kaiser wakes up every 2 minutes - it's killing the battery. It works only for 6 hours now
Help
bump!!!
No more people with this issue or any solutions?
Pls! Help
ive joined the gang!
I decided to flash my cooked rom ive been working on.
i hadnt changed much in the kitchen and i think the flash has went badly.
it starts booting windows and where it should state "calibrate screen" it goes white and hangs there, buttons seem to respond by lighting up when pressed.
Now when i try to get it into bootloader or even hard reset it just doesnt work.
it just restarts the phone.
before this happened the backspace key hasnt been working for ages.
anybody got any ideas??
(lucky for me i have a backup kaiser!)
I'm having the same problem. Automatic wakeup, applications starting automatically, can't use keyboard, have to to use screen to use phone etc. I've hardreset using the clear storage method, reflashed a couple of times, but nothing helped. So here I am joining the club
If it's not a hardware issue, then try to flash another radio, many of the custom ROMs here doesn't include a radio, so if it's caused by a wrong radio, flash a new ROM without a radio doesn't help.
Check the Sticky for 'how to' if not aware.
PS: Check here for something need to know..
The question is.... how do I flash the device if I cant get it to go to boot loader and the OS wont boot properly !?
I think its an official Brick!
the really odd thing I've discovered is sometimes the OS leaves the loading screen on, and when it does if I press the FN and folder key, I get explorer up but its not responding... I haven't tried inserting a memory card yet to see if I can access that.

Try this:
1. Take out the battery from the phone.
2. Take out SIM card and SD card.
3. Press in and hold the CAMERA button.
4. Plugin to your computer using the USB cable, while keep holding press in the CAMERA button.
See does it enter the BOOTLOADER mode.
Once entered the BOOTLOADER mode, you can flash a new radio or rom right from there, in your regular way of running KaiserCustomRUU.exe.(Since you already have a HardSPL flashed on, otherwise a HardSPL is needed to flash first.)
Good luck.
Edit: If the power button and the camera button is still working, you can use the regular way of entering BOOTLOADER mode, and flash from bootloader mode or flash from SD card.

To enter in bootloader mode:
Simply Switch off your phone. Press and hold camera button and also press and hold the power button..You can remove ur finger from power button when phone is switched on but keep holding camera button until u come to bootloader …Now attach the usb to ur computer and do the flashing you normally do.

Thx for your suggestion:
I tried removing battery as sim and sd were already removed due to previous attempts in fixing!
so:
i removed battery (did not put back in), plugged in while holding camera
got nothing, so held power button at same time, the green light came on, then went off, and came back on again. but no bootloader.
i tried same procedure with battery in, and all i get is the OS loading up, no bootloader no matter how long i hold the buttons.
is there any other alternative method to get into bootloader (possibly involving other button presses)?
or any other ideas.
Really want to fix this as it was my "experimental" phone for cooking roms with.
Thanks again.
Suspect you have some hardware issue with the camera button. Can you ever take a photo with it?
Edit: Did you read through every post onthis thread:
MTTY (How to fix a bad ROM flash!)
If you tried that and still no luck, you can post your questions there. There are masters will keep an eye on that thread. And generally they only have time to look into their 'subscribed' threads, chances are they will not look into here.
Edit: Maybe the procedure I told is wrong, since I call from memory, check this:
dwny said:
If you have a bad flash....that's no reason to worry.
I haven't had to use MTTY to recover.
In most cases, if there's no issues with the Rom itself...you can pop out the battery and re-flash the same ROM from BootLoader Mode. This will also work if for some reason your computer crashes or loses power & restart during the FLASH.
If the Rom has issues.....the flash will not complete and the device will be stuck in BootLoader Mode. At this point,you must FLASH a FACTORY ROM!!
Pop the battery off 1st, power up the device, device will power up in BootLoader Mode, connect to pc & FLASH your devices FACTORY ROM. This will restore your device back to it's original out the box settings.
The above only works if the device has been put through the Hard SPL or SuperCID process.
I personally have never tried to flash a cooked ROM without unlocking any of my devices. From what I've read what others have experienced...the flash would just fail and they're stuck in BootLoader Mode.
Myself ... I've experienced bad flashes, bad cooked roms that I've cooked, lost power to a pc & had my pc crash during a flash. Listed above is how I've recovered. There is life after Bootloader Mode.
The only time you have to worry is if your device does not power up at all
As a public chef...it's your responsibility to set the parameters of your ROM! Meaning, Radio, HardSPL, program conflicts, etc.
You are not ultimately responsible if someone bricks their phone but if they pushed the issue, you could be hit with some form of liabilty because you failed on providing a simple Disclaimer that sets the expectation.
I hope I've been helpful.....

Edit again:
And try like:
Plug in USB first, and thenn press & hold Camera, Power button etc.
I remember once I read there is a way to enter bootloader without battery, just can not find the original again.

[Q] Strange Reboot Loop, searched forum Not Addressed

Hello All
I did search the forum and still not answer for the stranger reboot loop.
I got a phone call, and answered it. The reception was crappy and hear no voice. I then looked at the phone to see if call had dropped and it was frozed on the incoming call screen. I then pulled the battery and pressed the power button to turn on the phone and It would not power on. After multiple battery pulls and many many power button presses, still nothing. It was like it was out of battery. It was stitting on the home charger before i left the house. Prior to this the phone worked fine. Over the past week or two I had to do a battery pull may be 3 times.
I got to my car and plugged it into the charger and the orange charge led came on, on the front of the device. I then pressed the power button and it vibrate once as normal and then went to the multi-colored nexus "X." he screen went black and then vibrated once again and and was back at the mulit-colored "X." Then the loop starts.
In between the restarts I try to get it to boot into the bootloader by using the "vol down and power" and the "trackball and power button" and the white screen for the boot loader flashed for a milisecond the goes to black. As long as I hold the "vol down" button the while bootloeader or recovery screen flashes every 4-5 sec for a milisecond. As soon as I let go of one of those button, it automatically goes to the full reboot loop.
THis all happens when it is plugged into a power source. As soon as i unplug it, it goes back to the power button not responding. Again it acts as if it has no battery power. But it is in the 90%.
So i am unable to do any other step as in reflashing, and or doing a recovery.
ANY IDEAS any one.
I was running Cyanogen RC3. the latest rom with amon RA 1 7 1, korean radio 5.0.8
It was running perfectly up till today. when it went into its loop.
ANY HELP WOULD BE AWESOME
THanks in advance
DD
Plug it in to the USB, adb reboot recovery, reflash rom. Or even wipe and reflash if needed.
Sounds like it could be hardware the way you have to hold the keys down and you said it wasn't responding to the power button press.
ok thanks, ill give it a try.
here is my only issue. I am not using my original computer Mac. I just sent it out to apple for repair. So i am using my companies computer. I need to set up the AndroidSDK to be able to talk to the nexus. Since the phone will not turn on i can not load the drivers. and ive tried every way and it has not installed and i cant check because it wont stay on. it just goes to the loop. and it wont turn on if its not plugged to a power source.
Any ideas or suggestion.
SOrry I am an noob, so could you please be specific in your instructions.
I as of right now have insalled the Android SDK and i am unable to see the serial number (working on an old dell, running XP sp3) because it wont turn on.
It cant manually install the drivers because I cant turn the phone on to specify the drivers.
and
I using USBDeview, the phone also has to be on to erase all HTC previously installed drivers. i think. but there were none in the usb log...i think becuase they didnt install...agains because it would not power on...:-(
any ideas...please
DD
Also
Sorry excuse me if its a sort of a duhhh question...
even if i am able to load the device bridge, if the phone will not boot can i still flash another rom, or do a recovery. The phone is not getting past the Multi-colored "X" ???
DD
It should still read the commands when it's trying to boot. You don't need to turn the phone on at all to be able to install the ADB drivers, they are independent of each other.
As strange as it started, is a strange as it went.
This morning open the phone to pull the sd and the sim to put it in a throw down phone. I replaced the battery and cover and just hit the power button. The phone does a full boot and it appears to be working properly. the sd card and sim are fine. I the odd thing is i did this multiple times yesterday and last night. I pulled both sim and sd, replaced the battery and tried to boot with the same issues as named above with nothing different.
I left the phone on charge last night and it was charging for close to 8 hours and it was still showing the orange charging light.
So after it booted this morning, and i checked everything. It showed the same amount of charge as yesterday, right before it froze, which was 75%. So that is another strange occurance.
I plan on reflashing the rom and seeing how things go.
I thank you for your assistance and time.
appericate you helping out a clueless noob.

Captivate Power button not working and boots with battery automatically!

I got a captivate, over a year old, never had a problem been through many flashes and custom roms etc....
Well it was actually running stock rom (froyo) for a while and suddenly the power button stopped working and the phone automatically booted when the battery was inserted. I read about the camera trick, took a picture and pressed the button a few times and it started working again. A few days later the button stopped responding and also it boots with the battery automatically again but this time the camera trick doesn't work (tried for a while many times), I did the factory update to gingerbread just to try that for the heck of it and still nothing. any ideas, suggestions, or other advice??
I think you have a problem with motherboard. Even the power button is jammed, it won't turn on the device as soon as you put the battery in.
I had same problem with PC and came out the motherboard had problem.
Same problem as well. Just started yesterday/today
Could it be software?
I'm running hacksung v16/17
I tried doing data/cache/system/dalvik reset and then reinstall, but it hasn't changed anything.
I might do an ODIN restore but I thought it was hardware.
Its hardware..check out mobiletechvideos.com they offer a power button replacement service.
sent mine put for the same issue, got it back in a week, works prefect now.
power button not working
... that's a hardware issue ... or so i read
you can take it apart and clean it you find instructions online
or you can use apps (which allow you to use the volume buttons to wake the screen)
i use MIUI .. it has a built in function (to use the volume buttons to wake the screen)
Time to get a new phone. I wouldn't waste money trying to repair it, something else will break and then what? Take a backup of your apps and data.

Have you tried using odin 1 click to restore back to stock? That worked for me.
I just posted my solution here. See if it works for you, too.

Power button issue

I just discovered yesterday that my power button seem to be not working. Pressing it doesnt lock the screen and long pressing it doesnt bring up the power options. Tried wiping everything and still the issue remains. When I pull my battery and then insert it back the phone boots itself, as if the power button is pressed all the time (even though i can still click it and its not stuck). Ive been using rom toolbox for the power menu but choosing to turn off the phone makes my phone have a screen freeze, all other options work like reboot, fast reboot, reboot recovery etc. Anyone know how to fix this?
Edit: After a couple of days my power button is working again

How did you get it to work? Or did it started working on it's on? Thanks
I've seen that happen on mine, due to a bad USB charge port. Replaced it, problem disappeared.
Any chance your device sometimes thinks it is docked to a docking station?
Inexpensive part to obtain, less than 10 dollars (usd), takes about 15 minutes or less to replace.
In the 2+ years I've had mine, I've gone through 4 of them LOL...I'm hard on charge ports I guess.

It just started working again. When I turned off my phone to place my sim back and it didnt boot up automatically, I knew the power button is working again. Pressed the power button, device booted up and the issue is gone. I dont know if mh device thinks its docked, i dont have a docking station and ive never had problems with my charging port yet.
I've been using my N7000 for 2 years and this thing happened for 3-4 times. The lock button will be like stop working, sometimes it is like being press all the time and the problem will be sorted out by itself. Normally when this happens, the phone will be laggy and will reboot by itself. Is it a common thing for this phone?how do you get your phone fixed Kcube989?

[Q] Xperia Z Died Randomly?!?

I'll started off by saying that my bootloader is unlocked and I have flashed the Android 5.0 ROM (503b) from here: http://forum.xda-developers.com/xperia-z/orig-development/exp-lollipop-xperia-z-t2929369
Sorry if this is a bit long but I thought it'd be best to tell you the steps leading up to the potential death of the phone.
As far as I can tell the issue doesn't stem from a software fault as I've been running the ROM solidly for 2 weeks now with no issues apart from not being able to hear a call when I accept with something plugged in the headphone jack.
I wake the phone and go to unlock it and the touchscreen is unresponsive. I have known it to take a second or two to wake up so I gave it a minute then tried again.
No response. Screen hadn't dimmed either so I suspected it had crashed.
Held the power button and the power off prompt appears along with all my previous actions unfolding beneath it. Just for good measure I decide I'll reboot the phone as I sometimes do when it starts to lag.
Powered off fine. Go to turn it on and nothing happens.
Battery was on about 20% when I turned it off so I plugged it in and tried again.
No LED light when I plug it in, still no response to any button combination. No recognition over USB either.
So I'm going to leave it plugged in overnight as I've seen it recommended by a couple of people before. Just wondering if anyone else has had this happen and if you managed to recover the phone?

Unfortunately no. The phone is doing absolutely nothing when any key combination is pressed and i've tried plugging it in via USB and doing these in case the LED light had developed a fault. Still nothing.
