CM9 My Optimus wont turn on

Hello Pleashe help!
I have installed cm9, and for the night plug it in the charger, and now it wont turn on! It's plugged to the charger but nothing is working! Please Help! I cant turn it on! SO many thanks to helpers! Please guys!
I'll be so glad if you help me!

Have you tried a battery pull and then turned it on again? It could be a BSOD.

had the same problem (sort of) yesterday without the powercable connected, it seemed like the battery was empty while it shouldn't be, i fixed it using power+ vol up but i guess a battery pull should work aswell
sent from my LG 2X using cm9

Well i have tried for 5-10 mins to fix it, plugging it on the charger, and pulling the battery, this morning, but i can't get anything. What can be that for?
Can i revert back to stock (nVflash), or even turn it on? MUCH much thanks to everyone!
I really want to get my phone working, If someone can help me, i can give him some money in PayPal!
P.S I'm in school now, and with another phone! When I go back home i'll try what you say again! I left it in charge (from pc) and hopefully, it's because battery has drained or something! Thank you for the replies! I look forward to reply's, about how to solve this. Thanks!

had same problem this morning (left phone in charger for night).... i just disconnected phone from charger, removed battery for 10 sec, put it back - and phone is on...
only problem is that battery level was showing 999% (unknown), and after ~10-20 minutes it was 1% all the time (worked with 1% 2+ hours).. now it is charging again.. everything seems ok.
**
If it wont turn on, just remove battery, and connect it to PC while holding volume up key (or down.)... it should boot "upgrading firmware" mode... after just use smartflash and restore to stock.

hm... happend second time, when phone was on "wall" charger..
when charging from PC - no problems... when from "wall" charger - always BSOD after few hours...
anyone else have similiar problems?

I had the same as in OP during first night while it was hanging off the wall charger. It hasn't happened since, but I enabled "keep screen awake during chargin". I beleive I read somewhere here it should help with that.

Same problem here overnight charge and the phone wash dead.
After a battery pull it was ok.
It 's a bugg.

Mine survived overnight charging just fine...
And it rocks (ICS i mean).

Solution for Me
Hey i got my optimus 2x just yesterday on Starhub Singapore, and similarly, i HAD the same problem until i followed some post above about removing the battery, plug in the computer/laptop with proprietary usb cables, WHILST HOLDING THE VOLUME UP AND POWER BUTTON TOGETHER. Hold for 10 seconds at least
Nothing happened. So i didnt get the flashing menu or mode on screen
Then i put unplugged the phone, put the battery back in, and tried again, suprisingly the LG Logo came up, but now it hung there.
Removing the battery...
EDIT: I removed the battery, now working good. Hopefully this dumb sH*t wont happen again. Beautiful phone. Hope this solved everything
If not, try doing a hardreset maybe? Hold power + Volume Down Key BUT ONLY IF YOUVE TRIED THE ABOVE METHOD A FEW TIMES. cause all your data will be gone POOF

[HELP] Phone stays on for 30s only .

So, I posted this on facebook group, but maybe there is someone in here who can help and isn't part of the group, so i'm posting here too .
So guys, i have a situation here, i was charging my phone, everything was okay, then it started to rain and started to lightning, the next day, when i took my phone off the charger, it wasn't working, it wasn't turning on, then i brought it to the support, they said everything was fine and even the phone was turning on, but not getting out of the logo screen, they didn't know how to enter in S/W mode, so i took it back and now the phone is with me, but it doesn't wanna turn on, even in the S/W mode. Then i ask you guys, there is anything i could do? If there is, please let me now, or do they lied to me ? I didn't want to get rid of my OB that soon. PS: I was using CM10.1 with ZeroGravityKernel.
The phone now turn on sometimes, stays awake for 30s and then blacks out .
I'm able to enter S/W mode but can't use Smartflash, it takes a least 2 minutes to use it D: .

what do you mean by only 30s? Like the battery dies after 30s or it just turn off?
Before sending your OB to service again change the battery instead it might not function well anymore due to the lightnings.
wait, Using smartflash you don't need a battery! So if your phone still turns off after 30s... it's actually the phone itself then...

try an "active boot" :
remove the battery, hold power key, then plug the charger until the logo appears. if the airplane mode was OFF, phone will boot, then reboot and will display the battery missing mesage. you may activate the airplane mode in a very short time before this occurs. from there you'll see if the phone stays ON or not. If not, that means this is a software or hardware issue. if it stays ON, that means there is a problem with the battery itself, or a charging issue

Nevermind. I feel so dumb right now

My Xperia is rooted, has recovery and the bootloader is unlocked, I use the stock ROM.
It went smoothly (done it several months ago), but yesterday, the battery emptied so I put it on charge. Today I tried to turn it on, but it didn't work; whenever I press the power button, the LED blinks red. I tried fastboot and flashmode, but none of it works. My PC detects it as an unknown device when I try to turn it on. once
If that helps, it turns on once in a while with CWM.
Anyone can help?

EDIT: looks like I used a loose cable and the battery didn't charge at all. God, I feel so dumb.

hello;
I had the same problem , I searched on the web for solutions and found something like charging phone overnight , key combinations but nothing helped; my phone was completely dead ; but I did something and phone is now alive; I removed screw of the phone , opened panel; removed battery connector and connected phone to wall charger , by this time phone showed sony logo like on startup , then immediately connected battery connector and left phone to charge for several minutes ; it was showing only sony logo when was charging, after 15-20 minutes disconnected phone from charger , screen went off and after this i reconnected charger, it showed battery screen and started charging with battery and thunder logo; thats all, it was the only solution for me.

[Q] Battery 100%, after unplugging phone can't start

Hi, first of all sorry for my bad english.
I just bought Motorola Moto G 2 and i tried to start it - white LED lights and the device isn't starting, i thought that its normal that the battery isnt charged because its new phone. I plugged charger and it showed me that battery is about 50% charged, and when the charger is plugged phone starts and works normally, when i unplug the charger phone still works (havent checked for longer time but didnt immediatly turn off, just worked), but when i turn phone off and try to turn it on again LED lights like its discharged.
I tried charging to 100% and unplugging, doing reset but still the same. Only works when starting with charger plugged. What should I do? Is there any solution?

If the led is lighting up for just a moment, you didn't hold the power button long enough. If device is not starting up even after pressing power 5-10 sec.... customer service

Phone doesn't turn on

Hello everybody, i have a big problem with mi P9:
i was to replacing my cracked display and the battery, so i bought them. Took off the old display, replaced with the newer and the same process done with tha battery.
But, after that, i tried to turn on the phone....nothing. No vibration, to display, nothing. I plugged it to the power adapter, and a red led started to blink while charging, tried on more time to turn it on, and it get the bootup vibration, but still nothing on the display. After the short bootup vibration, the led blinked faster for 2 seconds, than nothing. After minutes, the phone show the charging screen with the 0% battery, not growing up. As last chance, i tried to unplug the battery, reconnect to the power adapter and...boom, it booted up with the animation. The phone show the unlock screen with the PIN screen, but only for 1 second: Battery low, the phone is about to turning off, and so it does.
Now, i tried with a different battery, but nothing. I don't know what is the problem. I was supposing about the motherboard flex, maybe i damaged it while removing the old battery, but i'm not sure. Can you help me?
Thank you!
