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

[Q] Xperia T won't turn on or charge

Hi everyone ! I bought an xperia T two months ago, everything was perfect until this morning ! I was listenning to my music suddenly the phone turned off and when i tried to turn it on nothing happened ! I tried to hold the volume+ button and the power button but no vibrations or led light. I can't use flashtool because the phone can't boot on flashmode ! I plugged the phone on charge for several hours but nothing ! I really need some help because i can't send it back to sony !

Please guys i need help cuz i can't afford buying a new phone !

try pressing the power button while putting it on a charge. if it vibrates or a led comes it still is alive. If that doesnt work try a rubber band around the power button and then on the charge for 24 hours.

If its on charge get it off the charge and try vol+ and power button and hold it for a half minute till you feel vibrate. if you dont see the vibration.
If that doesnt work get it off the charge and try pressing power button and then put the usb in.

I keep coming back to these threads whenever my Experia T is acting up again. I finally bit the bullet and went the hardware way as described in a comment on Youtube https://www.youtube.com/watch?v=KWox7kCygRE
"In the end I fixed this problem by removing the back cover (one screw in where the SIM card goes) and detaching the battery supply from the phone. After a minute or two I reattached the battery supply (its a little yellow tab beside where you plug in the charger) and put the cover back on, plugged into charger and it started charging as normal."
It's surprisingly simple, to be honest.

I totally agree with you, this really works!

[Q] Broken Xperia Z

Hi everyone!
4 days ago i washed my phone for about 10 seconds, phone worked normally. After 1 hour i saw water went into both front and back camera. I got out all flaps and after some hours cameras were functional again. After even more hours buttons started to act weird. Sometimes power button wasn't working, sometimes volume up was acting like power button and so on. I tried to restart the phone, sometimes it went into safe mode(probably volume button was pressed by itself). Finally I couldn't start the phone at all(perhaps the power button stopped working at all).
After that i calmed down and put my phone into rice(hoping that would absorb water if any). After 24 hours i had no luck. When i had connected my phone to computer, the led was red, phone vibrated 3 times and then again and again.
Next step was to open the phone( removing the back with a hairdryer), took out the battery and trying to dry the phone with hairdryer. Still no succes. When connecting to PC and start flashtool, my phone wasn't recognised. I installed Sony Update Service (SUS) and then when i connected my phone i heard that sound you often hear when connecting a new device to an USB port. Now my phone is seen by flashtool, but it's always in fastbootmode. I even flashed CWM and it worked.
The problem is that it seems volume up is pressed always so i can't enter in flashmode to flash 4.4.2, it always goes into fastboot.
When on battery the phone is dead at all. Still when i try to charge the phone, it starts, displays Sony logo then shows that it's charging (at first that battery was empty but after 2 hours it got full charged). If i press power button it shutdown.
To resume, when on battery nothing happens( the battery could be dead). When plugged to wall charger the phone starts charging( so battery could work). Power button does nothing at all when on battery, but works when phone is charging or when connected to PC in fastboot.
If anyone had any idea what I could do I would be very appreciative. If you have any questions don't hesitate to ask me.Thank you very much for your support!

Did you connect phone holding volume down key or are you connecting usb after that pressing volume down key

Even if i down't press anything, just connect the phone to usb, led is blue, that means it's in fastboot mode...so i think volume up is stuck, pressed.

or the volume pcb might have shorted

Please remember this for the rest of your life:
When you notice that water has went into your device.... TURN IT THE F OFF AND LET TIT DRY...
Using it while it's wet from the inside is really bad.

Update Guys
Today I've replaced that yellow connector that contains power, vol up and vol down buttons. I managed to enter flashmode and flashed the newest official rom .233. Power button and vol up work like charm, vol down is dead.
The problem is that my phone is stuck on safe mode(probably because vol down is stuck). I want to know if there's any solution to get rid of this safe mode. I read somewhere that changes can be made to the kernel so that vol down will be disabled for ever. If you know any ROM, any mod, whatever that disables the vol down button i'll appreciate your help.

HP Touchpad doesn't start or charge.

Hi,
My HP Touchpad will not turn on. This never happened before. Few times there were some small problems to restart, but I usually do the reboot by holding down the power and the home button and everything was ok, but this time it didn't work. I held it down for 15 and more seconds. I tried to push just power button for quite a while, too. However, it still does not wake up. Usual I keep my Touchpad in sleeping mode, and I didn't let my battery to drain but this time. I switch it off, and I didn't use it during 3 or four days and when I tried to charge it, didn't even recognize that it was being plugged in. The screen is still blank.
I tried to find any solution on the Internet, but everything was not useful.
You guys my last chance!!!
Are there any other ways to fix this?
All help appreciated. Thanks!!!
P.S.
My OS is Android Lollipop 5.1
USB cable is OK is charging my friend HP Touchpad without any problems.
I reset the adapter it means I turn this one way and later back.
I tried my friend charger from his HP Touchpad - nothing.
I left my Pad for few hours plugged - nothing.

One of mine died, I left on charger for I can't remember how long, maybe a week, picked it up and it was on. One other thing to try is pushing the home button 17 times. Good luck.

Thanks, it didn't help, but I'm still waiting for solution. I think that my Touchpad is not broken because before few times something similar happened, and I heard that sometimes when battery is really empty some people had the same problem.

Place on touchstone to fully charge up / boot up?

[Q] Strange (hard?) brick

Hi,
After many years of enjoying this magnificent phone the disaster came.
The phone discharged overnight and switched off. In the morning I had to send some texts, so plugged the wall charger into USB socked (a weak one ~500mA), after few moments a charging icon appeared and stated that battery has 1%. Ok, I really had to send those messages: I've pressed the power button and phone started to boot.
Sony logo: OK, purple wave, OK...
After 10-20 seconds it suddenly switched of, red LED started to blink.
I thought: OK, system startup needs a lot of power, maybe a charger is too week to keep up.
So I left phone for few more minutes to charge, but without success.
That was the last time I saw screen was on.
Phone is a C6903, running on a stock, rooted 14.6.A.1.236 with the recent XZRecovery.
Bootloader has been unlocked.
For the moment I've tried everything but opening back and doing the testport-trick.
When I connect the power only red led blinks (I left the phone charging overnight, no change).
When I try to enter flash mode: nothing happens but red blinking light.
When I try to start phone nothing happens at all.
But there is still hope:
I connected the phone to 2A charger using a magnetic cable.
Then I've connected normal USB cable to my PC, strange thing started to happen:
When I pressed volume Up (even after few minutes of connecting power+usb) the phone suddenly jumped to fastboot mode (blue led, it was discovered by PC, fastboot terminal was functional)
When I press power button, phone vibrates for a second, then the led pattern changes to: 1s red followed by 0.1s green, then long red, then it repeats...
I'm still unable to enter any recovery nor flashmode...
I'd really appreciate any help, have you got any ideas left how can I revive my phone?

Hi, this just happened to me, my phone has been dead for over 4 weeks with just the red led blinking. i tried the test point thing with no success at that point I gave up but last week i decided to get a new genuine battery and it worked it booted up. Your battery is just completely dead thats why it won't boot up!

Thanks for the info! I've ordered a replacement battery already.
I'll open my phone today and measure all voltages. I'll keep you updated.

Good luck

Yup! That was it (at least I think so, I don't have new battery yet)
The Al part of positive battery terminal was broken: I have no idea why, maybe because of age, oxidation and high currents that were drained from this LiPo cell...
Anyway I've managed to temporarily join two broken Al parts, kernel and recovery booted successfully.
Now I need to wait for a replacement battery.
Phone is alive again, thanks tilakpatel for help!
But the magnetic cable trick might be useful in other hardbrick cases: just connect magnetic charger, connect normal USB cable to PC and hold volUp. Phone should be able to enter fastboot even with completely drained battery...
