Stuck on S/W Upgrade Screen
Hi,
I, too, am stuck in the S/W Upgrade screen.
I turned my phone off and when I turned it on again I tried turning the volume down, but it turns out, that combination would lead one into the S/W Upgrade screen (sorry, noob). And now, I'm stuck at the S/W Upgrade screen. I want to turn it off again, but a friend of mine tells me not to because it might brick the phone, is that true?
My phone is not rooted.

I just pull the battery. Done that many times. My o2x still in good condition.
Thanks loads!
I've been contemplating if I should root this or not. I might though, when I get a free time. )

serious problem
Hi,
I tried to update my LG optimus 2x to android 2.3.4 but I forgot to turn "windows
Enabler.exe" ON and "UpTestEX_mod2_marwin.exe" stuck on upgrade stage at 4% so I just closed "UpTestEX_mod2_marwin.exe" and unplugged my phone. then I turned it (I exactly followed the instruction for upgrading in website) and phone stuck at "S/W upgrade ....: window. then I downloaded and followed the instruction for flashing the phone but after pushing "flash.bat" it stuck at "nvflash started" command and didn't happen anything after 25 mins so I stopped the window. then I tried recovery (push vol_down then power and release ...) and after opening up "Android recovery utility" I could go up and down on menus but I couldn't select it. I'm really confused what to do and will be really grateful if somebody help me.

To to reboot to recovery via "adb reboot recovery". If this isnt working, how about flashing another ROM again? And did you try emergency recovery in B2C tool?

How about OnScreenPhone (OSP)? It is a LG software, which allows you to control your phone from your PC, without using the display of the phone. See reference here: http://www.youtube.com/watch?v=Y_1P1ELNz9g
Another PCB? what do you mean with this?

He means what most people would usually call mainboard xD
They're all PCBs - Printed Circuit Boards
Btw, if the phone boots, and the display can work on another device...
I never disassembled my OB, but does it have any flex cable pluging the PCB to the LCD? Did you check it? Does the LCD have background light but not contents?

You do not have that Samsung logo when you try to power on phone? Do factory reset if you can, in recovery.

So you can go to download mode, but can't turn on the phone or go to recovery coz you only get the vibration, which suggest (ofc, lol) the phone won't even properly boot?
Everytime my battery is near zero and the phone shuts itself down and near total death, that's what happens. It just vibrates but nothing happen. IMHO, I don't think that you're facing bootloop or anything.
In your case, you said that you charged it and by the time you wakes up it's a goner. I would recommend trying a new battery for now. Your current one might be dead as in broken or something. Trying a new battery won't hurt.

I have the same problem, but a little different. I've thinked that was battery problem as you, i've bought a new battery, but nothing is changed. I was running JetMod. When my phone has low battery and than shut down i try to recharge it but doesn't work anything! if i try to turn it on it only vibrates (with black screen, nothing happened). The only thing that can i do is go to download mode, but for a few time becouse after 10 sec it shut down, so i think that it has not been charged.. I observe, when it was alive, when i try to charged it, that not many time he started recharging, i don't know why.. i've tried different plugs or with computer but it works only when it wants to..

I had same issue when i changed governor: cable plugged but battery don't charge ( i think )
Going to sleep, wake up and founded phone discharged.( when power up i had black screen and little vibration )
Remove battery, wait, insert battery, plug power cable, and wait if you see the battery logo charging.
Then Boot your phone.
If this not work ask to Samsung assistance
