CM9 My Optimus wont turn on - LG Optimus 2x

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

My xperia doesn't take the charge!

Hey, dunno if some one had the same problem but my xperia doesn't take the charge.
Its appened when the mobile has terminated all his battery, and know the charge is not accepted by the phone
help me please
Something perhaps similar happened to me, i ran my battery completely flat and then could not switch the phone on even when it was on the charger. So I left it on the charger for ~1 hour and then it switched on fine! The other possibility is that you battery is dead. Hope this helps!
Its not the first time its appened to me, and the first time i had the problem i try a lot of time to recharge it, take out the battery, replace it etc.. and its worked.
But in 2 days, my phone is off :/
My battery is not dead i know, but how to recharge it
I have 2 computers from which I load it with usb cable. For some reason Mac Pro doesn't load the damn phone but Macbook does.
Try switching your "power" source. And sometimes when the battery goes really flat it needs many hours to even boot when loading up. One time I really thought the damn thing was dead for sure... But it came back to life
When you press the power button there's a red light next to volume buttons indicating it doesn't have enough power yet to boot up. If there's no red light then it's not charging at all.

Just leave if plugged-in and it will charge. It takes some time before it will charge if it is fully drained.
Ok thanks for reply
Have no real solution, but have the red light near to the volume button, or in the top of the phone.
But the phone doesn't take the charge at all...
The red light gave the battery charge, only that... have it sometimes and sometimes havent it...
Help me please
2 day less my phone know..
Ok i dunno why but the phone weak UP !
NICE
Ir was connected to the cpu and i presszs the button and it weak up
omg this phone
(Sort of) got it.
I'm not really an xda developer but id do have an xperia.
The same problem occured to my device about three weeks ago. I've noticed that the phone would still charge in the computer, but not by the power net adapter. (it must be broke i guess)
Today i've locked myself out calling the battery flat. I couldnt get it on anymore. After a lot of hassle this was the solution for me:
1) Connect the phone to a computer. Don't try to turn it on! Leave it there for about 15 minutes.
2) Disconnect the phone and pull out the battery.
3) Hold down the "on" button while inserting the battery back.
-- It should turn on now
4) Release the on button and quickly connect it to your computer again.
Hope this helps.
I just remember the red led lit on at the on/off button and the red light disappeared after 5 mins or so and i left for breakfast while it was still in the charger and by the time im back from breakfast, it turned itself on and was charging up

i had the same problem no charge and wouldnt booted up....but i took the battery out then placed it back in then charged it then turn it back on it worked fine for me....??
your usb port could be dead, you can try to charge the battery on a separate charger and put it into the phone and see if it works.
I have read here that some have had success in this situation by plugging into wall outlet, pulling battery while plugged in, putting battery back in while still plugged in. Havent tried it myself and cannot vouch for it personally. All risk is your own.
Hey I had the same problem, and it has happened a few times now. Remove your SD card, Replace your battery, plug your phone in: outlet or usb to computer. Attempt to power on, wait till led comes on, hit the power button. (mine did turn on but it would go to the nexus X and then restart). Then unplugged it, (my phone turned off when i did unplug it) then and use your regular power on and it turned on and did a long boot up process. I let it completely boot and then did a power down. Replaced the SD card and it was business as usual.
Hope it helped.
hey
thanks for the help guys i will try these

Help Novice here!

Hi
I have an SGS on Orange in UK and tried following this guide
http://forum.xda-developers.com/showthread.php?t=853950
using odin and got to the pass stage. Now my phone has gone off and won't turn on!!
Ahh am a complete novice, any help please??
Thanks
please anyone able to help?
sure it wont turn.. on.. if not you are hosed.. leave battery out for 10 minutes.. also battery may be dead.. couldve drained while screen was black and it looked off.. do you have external charger or another battery..
hi,
thanks for your reply. I tried connecting it to a battery charger but no response from the phone!
What a bugger, I tried following the guide and checking the 3 button thing worked before. Do you think Samsung would repair? Or does this invalidate the warranty?
You could try cleaning the battery contacts on the phone and the battery itself. I think there is a blow dryer trick some guys have used to get life back in to a non responsive phone. Just do a quick search on these forums you should find instructions.
Here is a thread with a video in it.
http://forum.xda-developers.com/showthread.php?t=772750&highlight=blow+dryer
So you say three button recovery doesnt work, and it was working before?
Download Mode works for me even if battery is 0%
Plug into charger and wait 10 minutes.
Then take out the battery and try to go to download mode without charger.
I dont recommend dryer.
Try homemade JIG, its easy to do.
It seems that you do something wrong, because all of this seems to be totally weird brick.
Indeed it worked before and now does not,
After flashing was completed, the screen went blank and stayed that way. I did nothing for about 10 mins and then disconnected USB and tried turning back on. Nothing. Power button does nothing. Power+Up+home does nothing. Power+down+home does nothing. Battery taken out and then reinserted does nothing. Battery charged does nothing
Am slightly annoyed at myself about doing this and quite frustrated!
looks like i'm up the creek then. will take it back to phone shop and see if they can send it back

[Q] Xperia Z, Hard Brick after battery drained

Hello, just about to pull the trigger on a new xperia ZU, but i wanted to see if anyone had any tricks for me to try on my Xperia Z. I was running near the latest CM 10.2 without issues for awhile now. Last night while i was bowling the battery died( nothing new happens all the time to me ). When i returned home i hooked it up to the wall charger for about 30 minutes, came back and still no life. I have tried multiple chargers and multiple cables with no luck. Device has been plugged into power all night and all day so far. When i attempt to power on with it unplugged i get the 3 pulse red led. When i hit the power button with it plugged in all i get is a solid red LED. Nothing more, nothing less. Cant get into recovery or anything. Most of the time a hard brick involves a mis flash or something along those lines....any idea what could have happened to mine?

It might be the battery...
Its not advisable to full discharge the battery but it seems that u did it a few times..
The battery might not take any charge as the red indicator means low battery...
Tried a new battery,i know after removing the rear panel n say good bye to water resistance but is worth a try...
Or u can send it to me for free if u wanted to throw it away...
hope this helps...
Had the same thing happen
I had the same thing happen to me. From what I read trying to troubleshoot it seems like the Xperia phones in general can take 30 minutes + after a full battery drain to even register that a charger is connected. I would try just connecting it to the Sony charger for a few hours and see if that works.
There is also a tip about holding down the power button when plugging in the USB charger and continuing to hold the power button until the phone turns on. Unfortunately, can not find the original post right now. EDIT: Found it. http://talk.sonymobile.com/t5/Xperia-T-TX/Xperia-T-Wont-Charge-Turn-On/td-p/252686/page/4
In my case the red light would not even come on when the charger was connected but would come on if I held the power button down while connecting the charger. After I did this for a couple minutes the phone booted and has charged normally ever since.
So its a mixed bag. Try just charging it for a while on the Sony charger or wall charger (not USB). Or try the power button trick.
Lesson I learned is I will not let the battery completely drain again.
Ahhahha it came back alive! I had tried pretty much every trick that has been suggested and it just wouldn't charge or start to boot. Left it on the main charger again last night and still no luck this morning. Again I decided to plug it into my computer's usb port( I did this multiple times already ) and I hit the power button, a backlight came on!!! and then sure enough there was the free xperia logo! I have no idea why it finally decided to power on, but its showing 1% battery so it was truly not charging any of the times it was left on a charger, computer or mains. Thanks for the responses guys, I appreciate it!
I know this thread is pretty old. But I'm having the same trouble. Xperia Z got bricked after battery drain. It wont recognize charging, i kept it on charge two nights in a row now. It did show a red LED while charging for some time and nothing else, but now its back to being stone dead. tried holding down the power button trick, didnt budge. I thought you can only hardbrick it by doing a wrong flash/update. dont know what happened in this case. is there anything else I should try or just take it to a shop and ask to change the battery?

man, try with a new battery, here in my country cost 14 euro . Or go in a service or buy a multimeter and measure the current of ur battery. Normal they from service will give u electrosock to bring it to life. And if will dont work i think u must sell it on piece and buy another
Same problem with my Z3 Compact: one day phone became hot and started to discharge rapidly and when battery became empty, cannot charge and cannot boot, only red LED is ON. I changed the battery and phone booted again. BUT when battery was discharged completely, phone cannot boot again, only red LED is on when trying to charge.
Looks like something wrong with motherboard is happening...
Xperia ZL battery completely drained, not starting up
I know this thread is old one, but I am having issue with my Xperia ZL. Its battery drained to zero and then whenever I plug in my charger, screen starts, Xperia Logo pops up, red light also starts and suddenly everything goes off. This goes on and on infinite number of times. Phone heats up but it doesn't turn on. I had issue with my battery, a couple of months back, so I replaced it with new one. If anybody has any solution about this, please let me know.

Dead Atrix HD

Hi.
My white Atrix HD is dead. It does not power and does not give any sign of life.
Phone was working perfectly, then it froze and after that it shuted down... never coming back. Was running stock.
First I thought it was the battery, but checking it with a voltmeter it shouws around 4Volts so it's OK for at least power the phone, I also recharged the battery separatly with an external charger...
Phone is still not powering. I tried every key comination to no avail.
If I plug it to my PC with the battery connected the green led appears for a while, then it goes off...
If I connect the phone to my PC with out the battery, then the green led stay lit forever...
What do you think it could be? Battery is dead? (It does supply voltage but you never know...)
Maybe a burned fuse on the motherboard?
Any help pinpointing the cause of the problem would be greatly appreciated.
Good luck!
Did you try to replace with other battery ?

Try this. While plugged into a power source, hold all 3 buttons on the right side. Once the light turns off, unplug the phone and hold the power button (top of the 3). Once it gets to the boot animation, you can plug it back in. Or you can just check the battery level and make sure it's not something wrong with the screen by doing what I said but never unplugging it.

Thanks for your reply...
Nothing... It's just dead. I think it might be the battery but first of of all it does give voltage and second i don't have other battery to test it. I could use another's phone battery but don know if that would work.
If ur adventurous enough to open up the phone like u would open up to do the EB40 battery mod, try to disconnect the battery completely by un-screwing the battery from the terminal for 30 seconds. Then connect back and try to power up. What you described happened to me once when I was doing the mod and it worked like a charm.
Good luck!
