[Q] Phone doesn't turn on. - LG Optimus L9 P760, P765, P768, P769

Hi guys,
I was attempting to pay my DTH bill through Paytm on my LG Optimus L9 P765 and the phone got stuck at the credit card info screen. I left it for 2 minutes like that and then pressed the power button for 10 seconds and the phone turned off. Now when I try to turn it on there is no LG logo .. I have tried pressing the buttons for hard reset and turning it on but no luck. The battery was at 95% when the phone was on. The phone doesn't even go into software update mode. I have removed the battery and re-inserted it .. still it doesn't turn on. I was running V10G firmware [rooted] with locked boot-loader. Help me guys..
Btw, the phone is getting hot even when it is switched off. The back panel temp must be around 35-36 degrees.

Does it start when plugged in?

Nope, just gets hot. No sign of turning on.

Well, if it gets hot even if it is switched off, I'll presume there's a hardware problem.
Take out the battery and have a look at it. Do you see any blisters, bubbles, loose foils/membranes or other loose or blown up spots on the battery?
Does the phone smell bad, burned or otherwise chemical?
Edit: You'd better keep the battery away from the phone from now on. Either it's a problem with the battery or there's a bricked component, especially in case it smells bad.
BTW - did you allow to automatically install updates OTA?

I can't see any problem with the battery except a straight line sort of thing running through it vertically towards its left side. The phone doesn't smell of any odour.. the top part of the phone (near the camera) gets hot if i put the battery on and connect it to the charger and then remove the charger after some time. I had done the OTA once.. a 16mb update.. it had got stuck at 13% for which I had to remove the battery and re-insert it. The update finished normally after that..

Well, that's the place my phone got hot whilst processing updates, too. Think it's the processor or sth like that but I was unable to find a photo of the mainboard layout of the L9 unfortunately.
Can you please try to connect it to your PC without battery and see if there's anything happening/appearing in the device manger (in case you use Win)? Perhaps try an "adb devices" just to be sure and in case you installed the LG drivers.
Bye.

[Q] Xperia X10 won't turn on.

Hi. The phone application was not functioning well and the F/C dialog showed up. I powered off the phone and from that point, the phone won't turn on.
The battery was fully charged before this happened.
When I press the power button, the phone vibrates for half a second, the screen brightens up but does not show anything but a black screen.
I removed SIM and SD cards, removed the battery and performed the above steps but nothing happened.
I also tried to put on the charger to see what's going on. Once I plug the charger, the phone's screen brightens but shows only blank (even without pressing the power button)
When connected to the charger, the green light for charging is on for some minutes, then goes off automatically.
I tried to connect it to the PC, and PC Companion finds the device as usually. It even shows the dialog on the pc screen to mount the device.
I tried a hard reset, but does not work
On some point, the sony logo appeared and then a dialog saying: "sorry process system is not responding". The first time I pressed Force Close and the phone turned off. Immediately after that, the phone turned on and showed the exact message. I pressed "Wait" but nothing happened in the next 15 minutes.
I called Sony's support center and they suggested a software update. Did the process exactly as it should, but again, even after the software update the screen shows nothing but black. It is all the time brightened for some reason.
I tried to turn off the phone for some time by removing the battery, but as soon as I put the battery back on, the phone's screen brightens and stays that way forever.
The phone was functioning perfectly up until this issue. The only application I had installed apart from some games, was AWDLauncher. On the screen I had only a TASK widget and a battery status widget.
The phone is 3 months old and has been always in perfect condition.
ANY help would be appreciated!!!!
Many Thanks

I tried the steps found in the link you gave me, but I couldn't go any further after step no (5) from the tutorial, as it would require to enable Debugging mode and I cannot access the OS (since the device won't turn on).
Is there a way to format all the contents of the device and have them replaced by running SEUS (as it always says that my device is up to date now)?
Was it this:

That Sony Ericsson told you to do?
If not, use that.
Download it, follow the steps when it says you have the latest version, press "Install Anyway".
Hope this works.
Hi itTim. thanks for the response
this is what i did but no improvement at all ((
Sounds like you broke your LCD screen somehow.
That would suck because I broke mine and it cost me $200 to fix.
Hi Hypercore.
Yes that could be the problem. The thing is that I always took rally good care of the phone, always carried in a leather pouch and never droped it. How sensitive is this lcd anyway?? Did you notice any cracks on your lcd or was the problem simillar to mine?
Thanks
When you turn on the phone does the lcd backlight turn on?
If so, look for any faint lines of color (usually a hairline size). If you see any of those then your screen is cracked.
the backlight is on, but there are no lines of colour on the lcd screen.
another weird thing is that the green light on the top blinks one or two times every time i put on the battery. even if the phone is off, once I insert the battery turns on automatically after a couple of seconds.

I had almost the same issue. Nothing worked. But, when I removed the battery and left it for a day (24h) without it, it just started working again. Still working without issues..
Good luck!

Phones are very wierd pieces of technology. I once bricked my k610i and that's a phone that's supposed to be impossible to un-brick, but out of nowhere a month or so later i picked it up, hit power and it turned on perfectly. Made no sense at all, but it worked.
Taking the battery out for a long time probably took all the electrical charges from it (kind of like how a computer power supply / monitor can hold power charges) and reset your handset.

if you have done this and did not worked , then it is the LCD.
send it to workshop and check it there.
Guys i Really need the solve of this problem , my xperia has blank screen now without backlight and the phone completely doesn't work . when i put the battery and prees the switch botton it gives me 3 red signals , i've updated and hard reset but it didn't work , and btw the LCD is fine , any idea. did removing the battery worked???? . please answer
After a looooot of time since my latest post, finally my Xperia came back to life. There was a battery failure which means the phone was ok all the time. Weird thing is that the led light showed that the battery was charging ok. I removed the battery and after a lot of time it is working ok again. This was really really odd.
FYI for anyone else that gets this issue.
I just had this for the past hour after trying to change my baseband....could not get it back for anything.
What I did finally try was run another baseband via flash tool, connected to usb and it started flashing....after flash phone powered on again...yeah I agree with everyone, that is freaking scary when it happens.

Thanks for your help.
its not off, it's underclocked so low it can't even wake up the screen, higher your min clock speed to 600 and see if it still happens, of try removing setcpu or that other one that starts with a T.. whichever you use

I have the same problem, instead of switching off it just reboots, even if I power off from recovery.
What kernel are you using. I'm using Ninphetamine 2.0.5, with VillainROM 2.4.2, with Black Android Theme.
I'd rather not pull the battery, after seeing how flimsy the battery cover when I put it on first, I decided I'd try to avoid fiddling with it if at all possible

Well let me tell you about a little secret: if you hold the power button for 10 seconds the phone will shutdown instantly no matter what.

Doesn't work: it turns off, stays off for 2 seconds en boots up again.
I got same problem. Never flashed, never rooted. Got original 2.3.3.
I think I#ll try to flash it to fix it.
got a similar problem. probably not related. after unplugging it from a full charge, the phone kept making the "USB connected" sound. when turned off, it would do one of two things: display the big battery charging indicator while flashing the overheat indicator or turn itself back on.
while powered on, the battery icon will change from charging to not charging. I checked the USB socket and doesn't seem to be malfunctioning and there isn't anything shorting out the contacts. so far now, the battery level is at 87 percent after 48 minutes not in use. and now it's not making the sound anymore. I suppose the battery is malfunctioning.

I got a mixed-up thing of the issues on this topic..
When I take off the power socket, the symbol that shows "charging" remains there, and also, it is completely impossible to turn off the phone..
Whenever I turn it off, hard, or standard mode, it turns on again after 2 seconds..
And even if I remove the battery, I put it on again, and then it's back on in 3 sec....
Uh, and when I plug the charger in, when the battery is completely discharged, I have to take it out and back in , several times, before anything appears on screen, and even when it does, there is a temperature warning sign , and a yellow one which usually appear...
I'm getting very frustrated since I just paid 5000 nok (920 USD) for this phone..
And while I really begun to like Android, I guess I'll have to switch back to iPhone with a 4S, or to some better android device, since yes, the gs2 is cool , but I can't stand such issues, since I do run business things, and the phone is of vital importance for me, and not just a console/browsing crap.
Has anyone got any solution on this issue?
It would be crap if I had to send it to service, since it would take a lot of time, and I would have then to buy another temporary phone in the meanwhile...
PLEASE, HELP!
I had this problem, i cleaned the USB port out but that didn't stop it, but i think it helped. I then drained the battery to nothing and it has now stoppped. It's a battery problem, as it didn't switch off like it does when it hits low battery it just died. The battery readings were also inacurrate and every now and then it would do a weird thing like flashing it was charging, but it wasn't. I tried software etc.. and clean wipe before i tried the hardware, so it wasn't the rom i was running. I think the battery is on it's way out, so I've bought a new one.

Did this actually help? I had all the symptoms everyone has been describing and sent it to Samsung for repair. Their response was that the phone was stuck trying to download a PRL update, but as soon as I got the phone back from them and charged my battery to 100%, removing the phone from the charger caused everything to start again. I'm not entirely sure it is the battery, but have no other ideas.
USB charging port is dead.
Buy a new one on ebay and replace it.

Hi all.
Had similar problems about one month after getting my s2. I have unlocked sim card, rooted it and flashed some kernel, shyah i think. And left it with stock rom (Android 4.0). As it was under warranty i reverted completely to stock and took it to the carrier. After one day got it back but they said it had no problem. The fact is that i could in fact turn it off again. After a few days it was back so i flashed a custom rom (resurrection remix at that time) and never had it again.
Now I'm with alliancerom and apolo kernel for a few months and never had it again.

Battery will not charge due to high/low temperature (not a battery defect)

Hey there,
I have my Vibrant for a good year now since it came out pretty much. Last week it just stopped charging out the blue. The battery is completely empty and shows a thermometer with a warning sign and stops charging seconds after its plugged in. So I assumed it might be a battery malfunction and I got my spare battery in as soon as I came home and tried charging - same problem. I think it is highly unlikely that both batteries fail at the same time. Therefore, I assume there is something wrong with the temp sensor in the phone. I saw a few people have a similar problem with the epic 4G, but the discussion got really side tracked by other issues. My phone is rooted, but I was running stock froyo, so that shouldn't be the problem or should it?
I just wanna know if anybody had the same problems and if there is a quick solution, I google and forum searched a while but as soon as you throw in the term battery it gets spammed with battery life discussions.I just checked my files I have on the phone, apparently I have the premium insurance - does that mean I just can go to the next Tmo store and get a replacement? Any feedback is greatly appreciated.
Phill
Well for your problem, i suggest you try a different rom and see if the problem persists... maybe its a bug
And as for insurance, you mail the phone in and pay a deductible, which should be like 135$ or so. They send you a refurb.. or if you say it wus lost, you dont have to mail in phone

thanks for the quick reply. Is there a way to reflash without a battery?
I don't see it as a bad thing. If your phone gets too hot and keeps charging that's going to burn something inside. When my phone won't charge I know I have let it down. So it can cool down. But to fix your problem reboot the phone. You can keep charging it after it boots up

Sent from a cell tower to the XDA server to you.
Mine did something similar. I picked it up after putting it on the charger. It was hot and would not come on. I unplugged it and let it cool off for a while and it cleared up.
I got that message once...
Vibrant was in a car dock, with power.
It was *HOT* out and sun was hitting the back of the unit. (A/C on of course)
Google Navigation was running (display brightness max)
Google Listen was running
Bluetooth was passing music to a speakerphone
When I run the phone with that setup, the charger can't even keep up with the phone power needs. The battery level slowly drops. No question the phone is working hard.
This was a true heat issue... I removed the charger and turned off the display to let it cool off a bit. (I was almost home).
So the question again, is your phone hot or is it a false reading?
Robert
Hey,
I am sorry I didn't clarify the actual battery temp. It is normal - so its neither in the sun or in a too cold spot when I try charging it. The phone probably runs for one for a few seconds before turning off so there is no chance of the battery stats wipe. I think I will try to find an external charger and try to charge the batteries this way to have enough juice for flashing a new rom. Thanks for all the replies!
Does it charge the battery with the phone off? If not, I don't think a new ROM will help.
Hey there! Wondering if you got around to solving this. I've got a Vibrant doing the same exact thing. Battery being cool it sais that is overheating. Did changing the ROM solved it or not?

Sorry for resurrecting an old thread, but a resolution never seemed to be made here. Has anybody found a fix to this?
As of yesterday, my wife is having the same issue with my old Vibrant phone which she now uses. It's flashed with Bionix V 1.3.1 and Tigerblood overclock to 1.2ghz. This could be the issue, the Tiger Blood overclock, but I'm not sure. I'm out of the country for three weeks and currently she's left with a dud of a phone that keeps giving her the temperature warning in the triangle when plugged in while the phone is powered off followed by it stop charging. When she turns it on, she gets to the SD card check and then the phone completely freezes. Once in a while it's able to stay on for a minute or so before freezing, but more often than not the phone does not fully turn on and just goes frozen after a few seconds, sometimes at the Tigerblood logon screen before making it to the desktop. Me being 4000 miles away doesn't make it easier to help her but I've recommended she leave the phone unplugged, battery out for the night to see what happens. I also told her to take off her silicon case thinking maybe that has something to do with the overheating. Well after 7 hours of her letting it sit to cool off like that, with the case off, she plugged it back in and is having the same issues as yesterday. Absolutely no progress made. One of her colleagues said she should try leaving the phone in rice confused:) so she's giving that a go and another guy in a phone shop who she went to for advice after work said that the motherboard might need replacing. I'm convinced all it needs is to have the Tigerblood removed or reflash a rom onto it but there's really no knowing unless I have it in my hand.
Is there any quick fix to this problem without having to do all that? Surely there must be a way to charge the phone without it heating up and freezing up. She's tried plugging it into different rooms, on her laptop, etc, none seem to get rid of the temperature problem. I've had the phone since August 2010 and never had any issues with it. I also never once saw that temperature error message so was taken aback when she showed me it over skype. I just upgraded to the S3 and gave her the phone 2 weeks ago, but surely it shouldn't just die out just like that? Thought the Vibrants were made tougher than that?
Any help would be greatly appreciated. Much thanks in advance
Its most probably a kernel issue or a bug in the rom; so the only way to find out is to flash another kernel/rom..

Will be looking into reflashing another kernel/rom when I get home in a few weeks time, but it must be noted that the phone has been showing no signs of life for the last few days now. After letting it sit out for 7 hours on the first night, battery out and everything, she went to plug it in the following morning and this time absolutely no notification came up. Not even a lighting up of the phone or anything. No signs of life at all. Every time she hit the power button nothing occurred. The phone still heats up and after a few minutes while plugged in and gets very hot to the touch again but no matter how many times she attempts to turn it on, nothing happens.. She's tried plugging it into her computer via usb, into electric sockets in other rooms, even in the bathroom in one of the 115 volt electric shaver outlets in the bathroom (we live in the UK currently), and none of these ideas worked. Still no signs of life. It has been this way for three days now and is frustrating as I can offer no advice to her to get the phone to turn on anymore.
What on earth can be the problem? Has this happened to anyone before? And is there a fix to this or can we consider the phone to be a paperweight at this point?

Some kernels require a certain amount of power to fully boot the phone up and will not charge until it has 5% battery or so. I personally think her battery may be unable to hold a charge or like I said before it doesn't have enough juice to boot the phone because of the kernel. There is a way to charge the battery with the phone off. You can use ANY kind of usb cord, I used an old printer usb cable when I had to do this. All you do is cut off the side that is not usb and strip the positive and negative wires(red and black), then place the stripped wires on the positive and negative connectors on the back of the phone and insert the battery (make sure it's a snug fit). Plug the usb end into your pc and charge the battery that way, DO NOT let charge for over 2 minutes at a time. Wait five minutes and do it again if you have to. If she gets it to boot up, I would definitely flash a new kernel first to see if thats how the problem originated.

Phone dead, battery overheating, won't boot

One day when the battery went down i put my phone on charging, after some time came an error msg popup..
' your battery temperature is getting high force shutdown'
when i switched of my phone and rebooted it doesn't boot..
now the phone is dead..
guess the battery maybe drained. dont hav any alternate battery.. tried another charger , no luck..
tried pressing vol up key+home+power, no luck..
while connected to charger, phone heats up near the camera, under the sim slot.. (heats up even when connected without battery)
on warranty period, going for the service center.. is there anything else i can do?
If you have warranty I would just go that route. Even if you can bring it back to life it may have caused some damage to the internals and would probably crap out again.

yes im worried abt the internals, it heats up like an oven, seems lyk the boardn is shorted inside somewhr.. im goin for the warranty, but it would take time i guess..
did anyone else hav the same problem?
Mine also heats up near the camera a fkin lot..
LG L9 P765
If im replying you..then be a good bytch.....
Got my mainboard replaced from Lg service center.. got it workin, but now i hav noise and disturbance during call...
LG Optimus L9 P760 can of course overheat itself then force shutdown.
Instructions:
1. Wait until your device cools down completely.
2. Plug charger in. In case your battery was entirely empty, after plugging the charger in, your screen may not respond for a while. It's because your device hasn't got enough voltage to turn screen on. Only thing you need to do is start charging your phone and even if it doesn't seem like it's being charged, leave it that way. After 10-15 minutes press home button to see if screen is back alive. If yes, you're fine. If not, take it to service.
I hope this helps.

lgog not starting or charging.

lg e970 battery does not charge. when plugged into charger, few things happen

This exact thing happened to me about a month ago. Whats happening is your battery is basically dead/at 0% or 1%. When you try and charge it the phone gets hot so it's not gonna charge.
What i did was literally put the phone on ice. You gotta get a bowl big enough to put a bunch of ice in, then put some kind of layer over that. Like a bag or foil. Something to keep your phone from getting wet. Now sit your phone on top of the ice and plug it into the charger. The phone is gonna slow charge and it'll take a couple hours to charge 4 or 5%. Wait 3 hours while keeping it on ice/charging it. Then take it off the charger and it should turn on. Now put it back on the charger and it'll charge normally. Idk how much of this made sense to you, but this worked for me after trying many other things.
Thank you so much. you have helped revive a dead phone. I followed your instructions to the letter and after three and a half hours found the phone to have charged to 60%.
The ice really worked. The heat wasn't allowing it to charge.

I'm glad yours worked out but my case is a little different. One night I was playing games for hours and hours and while I had the charger connected so it wont die on me and when I started to notice that it's getting pretty hot, I put it down and its still charging and let it charge overnight. When I woke up the phone won't turn on anymore. When I hold the power for a long time it would start blinking but the screen won't turn on or anything and when I let go of the power button it will stop blinking, power + volume up or down combinations has not effect or whatsoever.
So I decided to connect it to my laptop thinking that maybe it got brick and I'll restore with LGNPST but it won't even recognize the phone, no matter what button combinations I make. So I was thinking maybe the battery was bad so I bought a new battery, removed the screws &cover but when I installed the new battery the damn thing still won't turn on. So now I'm thinking maybe it's the charging port, I have replaced the charging/mic module as well and went through all the trouble of disassembling the phone BUT IT STILL WON'T TURN ON!
I don't know if this method will work but it won't hurt I guess but considering I have replaced the battery already and the phone had already cooled-down since it's been days that I can't turn it on. ANYONE OUT THERE CAN SHED SOME LIGHT PLEASE!
farewell LOG
well for trying almost everything even to the point of replacing parts I guess it's time for me to say goodbye to my beloved LG Optimus G. It's sad coz this phone is pretty powerful and good looking too, I dont even think I've unlocked the full potential of this phone but it served pretty damn well and unfortunately I think it's out of warranty already since I've had it for almost 2 years now.
So Sayunara LGOG!

I could probably help with your problem too if it's not too late. This same thing happened to my mom's phone(She has the LG Optimus G as well) My first guess was to replace her motherboard. I ordered her another optimus g from EBay that had a cracked screen and cracked back for $40(make sure it's an unlocked phone). The internal hardware was all in working order. I simply replaced the motherboard in hers with the one from Ebay, and it worked. If you haven't gotten rid of the phone yet you could try this. I found a teardown guide on youtube that made it really easy to remember where to disconnect and reconnect everything to the motherboard. The only downside to this is it's basically a new phone and anything not stored on your sd card will be gone. It's like a factory reset.
hey mate, wow I didnt think anyone would reply to my post anymore.. thanks for replying, anyway no I havent gotten rid of it yet though I already got a Galaxy S5 if I can fix it soon I can still return the S5 coz right now I'm not happy with it coz of the locked bootloader.
I was actually thinking of doing that since I've already gone through all troubles of replacing the mic/charging port module so why not just continue experimenting on it. I will follow your advice but do you know anywhere or anyone else I can find just like the one you got?
Your advice is greatly appreciated, thanks
