[Q] Phone doesn't turn on - LG Optimus G Pro

My phone doesn't charge or turn on. The menu button + back button just flashes. I tried changing batteries ( bought a new one), leaving it on the charge for a day, nothing seems to work. I tried to factory reset it, would not work either. (it goes to the screen but when i confirm nothing happens and the lights start to blink again). I would appreciate any help that I could do to get my phone working again.

try to open your phone internal logic board and reconnect the cables

Brick : Flashing Red LED + Soft Buttons

I tried flashing http://goo.im/devs/TheShadow/geehrc/ZVB-Stock-Rooted.zip
This morning after having the unofficial rootbox version on there. Well it somehow bricked in the middle as I left it installing while I went to dinner
Now it's dead and flashing the red led and white softbuttons one after another if it's plugged in a power source. If not plugged in I can't get it to respond at all. I tried LGNPST and it works in download mode but even after that I get to 85% and the same thing happens with the lights.
Not sure what I should / can do I need to rescue my picture folder from the phone

looks like you flashed an LG kernel on top of an AOSP ROM. You might have to do a battery pull.
Ugh Didn't know I couldn't do that. Sucks... I am exchanging this phone anyways but did not backup onto my computer before trying to flash a clean copy to return back

Do a battery disconnect. It's pretty easy and has fixed the problem several times for individuals that I know personally. Good Luck!

Yup, I had to do a battery pull to recover from the same issue. You will need a Torx T4 for the bottom screws, and a 00 Philips for the battery connector. Just be very delicate, especially when disconnecting the terminal. Good Luck!
I get this everytime my phone's battery runs out. Im stock rooted and for some reason my phone stops working. It happenes to me two days ago,and just got it working this morning. When the lights start flashing i hold power and volumedown and it gets rid of it. But then my phone overheats if i dont go into the bootloader. I guess the last part is my problem though.
Battery pull worked! The problem now is how do I get back to stock? I tried to LGNPST the ZV9 bin to it but it's freezing at the 4G screen.

How do i reboot the phone if the phone hangs suddenly? I have no idea about removing the battery and stuff. Is there any physical button combo to reboot?

Phone will not turn on

My phone worked perfectly fine for months until today. My cannot boot. When I turn it on it goes to the galaxy s3 screen before turning off. I have tried taking the battery out, sim, you name it and I still get the same result. Does anyone have any tips for me? Thank you

If it also happens in download and recovery mode, power button might be stuck. That or hardware failure.

I cant even get that far into the phone =/
But I think something must be loose in the phone. I got it to boot up but it was very jumpy and hard to get off the unlock screen. Should I try to open it up and check?
Good way to tell if it's a power button issue is to remove the battery, then put it back in and wait a min. If it tries to turn on by itself, the button is your problem.
If it doesn't, it could still be the button though. It won't rule it out but is an easy way to confirm it most of the time.
What do you mean by its jumpy and hard to unlock?

Desire HD won't turn on

Hi guys,
yesterday I tried to recover the original ROM for Desire HD. During the process in bootloader, my phone shutdown, and I can't turn it on now, even the bootloader wont run. I think my battery was too low, even tought the phone showed 99% (it happened before, even though the battery was almost dead), and it died during the update. Basically, I'm not able to access any feature right now, I'm not sure, if the phone is charging - when I plug it in, the orange light turns on, but when I unplug, the light stays on. Bootloader won't start, but when I press both volume buttons and power button, the phone vibrates 3 times, green light turns on, and thats all.
If you need more info, please ask.
Any help is appreciated, thank you.
You were recovering official ROM from the RUU? This should not result in your device being bricked.
Please try removing the battery for about 10 seconds, then press Vol Dn+Power button and a partial bootloader showing RUU failed or a similar error should open.
Then connect your phone to your PC and again run the Official RUU Setup.
Hit "Thanks" if I helped you. Also click "Donate to me" on the left if u wanna give something in return

Hi, thanks, nothing happens when I push down volume down and power buttons, even after removing batteries. I believe something is actually happening ,but nothing shows on the screen, because when I push volume down and power, and then I plug in the power cable, the orange light does not turn on, while when I plug it in without the combination, it does turn on.
I think that was an official Rom, because I've used it before, and my phone was not rooted afterwards - I did this successfully two times before. However, I recovered it from SD card (pd98img zip copied on the ssd).
Maybe you can try it...just try let the charge is plug in...n leave it be for a hour maybe...don't try to turn on the phone..
After a hour you can try unplug the charge...and remove your battery first...then put it in again...then try power on with pressing volume down+power button..just let see if this time the phone can go to bootloader or not..
Hope this can help..

yeah. I thought about that, but I dont have any desire hd battery here, and I don't know how to charge this one without the phone.
I appear to be having similar problems with it not turning on. when i plug in the charger i get no orange light atall.. if i leave it plugged in (usually within 1hr to 2) eventually it will boot to custom recovery and from there i can reboot the phone and will boot to android. but it does not last very long atall usually about 30mins. have reset battery stats from recovery but doesnt seem to help.
from what i can find online its dieing but can anyone advise on if it will be the battery or the phone itself???
i have just spent $30 fixing digitizer and lcd in the past month. if it is needing a new battery i will proberbly do that but if not it can go..
hope this may help with your problem or any other....

probably won't help my problem.
but to solve yours, download one of the apps that tells you how much battery health you have. You might also get a pretty good deal on a new battery from ebay

Need help with dead phone

I have this M8 for awhile and out of nowhere, today it's just dead, can't turn on or do anything to it. I was talking on the phone then it just hang, so I turn off the screen and it went black after that. Tried to turn it back on, boot to bootloader, but nothing work, it's just black out. Any advise on this ? Thanks. Last I checked, the battery is on 40%.
PS. This phone has not been mod or anything like that, just got this phone for a few months so don't want to do anything to it yet. So basically, this phone still untouched with any mod.

Try a "hard reboot". Hold Volume Up and Power for 10 seconds.

Oh that's good then, was just about to suggest that you find Kisuke Urahara and make that device a Shinigami too. :silly:

Did you do something before the phone got that problem?. I mean a firmware flash or something

No i didnt
So, it must be a hardware problem, right now I'm having the same problem but I did flash a ROM and something went wrong
Did you try pressing the reset button? (Yellow one located beside the microSD card slot)

how long did you leave it to charge ??since i see red notification it seems you battery is low
if you did leave it for over night .. i read somewhere try pressing volume up + power until it vibrates then leave it on wall charger for couple of hours.
if these things doesnt work we will take it a step further

Can you connect to flashmode you can flash ftf to check if its a software problem. But i highly suspect that its a battery problem. i would suggest you to keep for charging for few minutes and then do flash using flashtool

So i left it on charge whole night and then i hold vol up + power and plug the phone into wall charger and it turned on and battery showed 98 % charged but as soon as i removed the wall charger it turned off and then i tried to turn it on it wouldnt turn on unless i plug into the wall so it is definitely the battery?

I think it's about hardware issue.
Send it to service center, I think they won't find out if your bootloader is unlocked, because yours won't turn on
