Your user name suggest me that you have a LG P999 which is LG optimus G2X. So, before you do anything can you check the sticker under your battery what does it say? If it says that LG-P990, then download the drivers from here and install, then try to flash a rom again with smartflash. If the sticker says LG-P999 then go to this forum.

Thanks for reply, but luckily i managed to get driver installed on WIn 7 and used Nvflash and ClockworkMod Recovery to install Jellybean. happy that phone is running, but i am disappointed with signal quality and battery life. i am not buying any lg phone for sure.
hi, iv rooted my lg optimus 4x HD device,
i have eur 4.1.2 v20a stock rom.
after that iv installed cwm by the instructions in this link:
http://forum.xda-developers.com/showthread.php?t=1826378
when device reboot, it gets stuck on the lg logo screen and wont resume.
iv tried:
1. reboot
2.all types of wipe the device is not recognized by my computer, and pressing vol(-),
doesn't offer me the possibility to update software.
is there a way out of this??
I take a quick look at instructions and they are for ICS. You did it wrong.

is there a way to revert back..
cause for now i cant start my device,
and it is not recognized in my computer so i cant do anything.
You couldn't go to S/W mode? Charge to full, battery out and in and then volume - and powerbutton? There my knowledge ends, sorry Next time read instruction.

Did you try to hold the - key down while plugging in a usb? (pull out your battery) if that succeeds then you should use kdz flash tool to revert and AIO Tool by OS_Hacking to get a proper recovery.
Hi,
I’m trying to upgrade my Wind Mobile Optimux 2x from 2.2 to Android 4.2.2 (CyanogenMod Nightlies). The Clockworkmod identifies my phone as LG G2X; I tried to manually select Optimus 2x but flash recovery failed. I kept it as LG G2X but each time that I tried to flash with a P990 ROM (Optimux 2x), it was unsuccessful and I had to factory reset it by pressing Power and volume down key.
This time, I selected P999 ROM (LG G2X) as I read that it’s the same as Optimus 2x for T-Mobile...but now it stuck at the LG logo (with blue/purple background lines) and pressing Power and down key doesn’t work anymore and it stops at logo again instead of resetting.
If I hold the volume down key until second LG screen, it shows: S/W Upgrade Please wait while upgrading... and it stops there forever...
What should I do to resolve the problem? And is there a way to go back to factory setup mode?
Thanks

First of all, check the sticker under your battery for whether your phone P990 or not. Please let me know what type of phone do you have P999 or P990

It's P999. I spend several hours to research about it and tried different applications...One-Click-G2x-recovery-flasher-04-28-12 and CWM_5.0.2.8_P999 cannot flash the device and give the partition download fail error, maybe because I previously used AIO-P990-ToolKit_v5.6 to nvflash it as APX drivers are installed and USB cable is working well. I tried different custom recovery versions using AIO, ICS-cwm-6.0.3.1, ICS-cwm-6.0.2.5 (before knowing that I have to use G2X), ICS-cwm-5.0.2.8e and ICS-cwm-5.0.2.0 but was not able to flash it as it goes back to recovery mode after rebooting, instead of running the new O/S.

I can do for you a nvflash for your p999. It will recreat all partitions and etc and will flash cwm p999 recovery to your device. Search custom roms on the optimus g2x forums. It will take some time since i have to download a stock p999 rom and gather the necessary files
Download my attachment and run flash.bat. It repartitionate your phone to p999 layout and flash cwm as well. Do not flash p990 custom roms with cwm to your phone, because p990 and p999 partition layout is different.

Thank you for your reply. I finally could flash it using G2XCleanUpBatch5028. It turned out that CM7 unlike what I thought is 2.3.7 not 4.x and I already found some problems in it...I'm trying to find the original Wind Mobile ROM and a way to install it back on my phone to keep it as my factory reset backup to return back to it in case that I could not find a reliable custom ROM.
By the way, I'm wondering what's the difference between your attachment and the one (G2X_V21E_00_NVFlash) that comes with 450MB ext3_system.img file?

My version of nvflash I skipped the system image, because I assumed that you are going to flash a custom rom. So that 445 mb differnce is teh missing android OS.
You can find your original rom at http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=0000000000000000 , replace the zeroes with your IMEI number. It will give you the download link for your current stock rom. It is in kdz format. If you having troubles flashing kdz, then give me the link to your kdz and I am going to make you a nvflash rom from that.

hello !
I'm a in trouble with my friend's Optimus 4X HD.
We tried to install CWM but i made a mistake. i instaled the apk of the recovery but since this, the phone juste dont boot up. The LG logo just blink over and over ...
We still can acces the stock recovery (tried wipes but did nothing). And we also can get acces to the download mod (strangely only withe the battery in the phone. if it is out the screen display stranges colors ... )
We tried to fix it following tutorials showing how to flash a .kdz but all the softwares shown just crash.
If you have any idea ...
Thanks a lot ! And sorry for my english :s

Force an update using the LGMobileSupport tool while in download mode. The option is in the upper right menu's. That should bring the device back to life.
On why you got in a boot loop: you tried to flash a custom recovery without unlocking the bootloader. Please read a little more before you try again.

hey guys, thank you for your answers
we already tried to follow the tutorial you sent sonyc2011, but i dont understant why, most of the softwares we are supposed to use just crashes.
But we found an other tutorial (type : "How to Return / Unbrick / Downgrade LG Optimus 4X HD" to find it) that worked perfectly !
So we installed the old ICS rom, we updated it to 4.1.2, then rooted it. now we are working on unlocking the bootloader. And we will THEN install the recovery .
Thank you again for your help and sorry again for my bad english !
