Dear All,
First i installed cwm recovery from this thread http://forum.xda-developers.com/showthread.php?t=1007863
, it was success but can't do nand backup, so i use rom manager and installed cwm recovery from there and success.
after that i choice boot into cwm recovery from rom manager, phone was restart but stuck in LG logo.
i tried to take out take in the batre and do normal boot on the result is same "stuck in lg logo"
i also tried to enter to cwm recovery by press power + vol down but still same stuck in lg logo
would you please help me ?
Are you holding your fingers on both power and vol down button for long enough? It can take up to 5-6 seconds to enter the CWM

Ohh no, Seems like I have the same problem
Ohh no.. Seems like I have the same problem.. The phone is stuck on the LG logo.
I installed the Cyanogen mod successfully, and everything seemed to work.
Then i started Rom manager to install Clockwork recovery. The clockwork mod was stuck the first time, don't know why!
So I restarted the phone, and tried installing the clockwork mod again, this time there were no problems.
After the clockwork mod was installed I wanted to install the Google addons, so I went to Download ROM, and pushed Google Addons. The phone asked for a restart, and during the restart I was stuck on LG logo.
I would be very very happy if anyone can help me?
Hi, i think you must use the nvflash reset-all-phone procedure.
Search google for "NVflash stock ROM release" and you'll find the procedure and the download links for APX drivers and zip with rom images and tools.
Good luck ! (I made the procedure 10 times in 3 days past bricking my phone..)

Thank you very much, I succeeded in doing a flash through nvflash, so now my phone works great again
Do you know if you can destroy the nvflash possibly? .. just so I know if I play with the phone as much as I want, and always get it working again with nvflash if something goes wrong

My LG Optimus 2X from windmobile is stuck in boot screen. I recently rooted my phone which worked perfectly fine than I installed CWM ext which messed things up, phone was hard resetting every time it started up. So I went to the market place and installed CWM and installed recovery from within the app and decided to install [ROM] MIUI v4 2.7.20 [Multilang][New base] [25/07/2012] through the CWM app. It loads up in recovery FINALLY and I installed it. After reboot its just stuck on LG boot screen I cant go into recovery mode either it just reboots and gets stuck at boot screen. is there anything that i can do to recover the phone?
how u tried this? - http://forum.xda-developers.com/showthread.php?t=1006745

hey so NVFlash did work but now i am getting no signal, I went to settings> About phones > baseband: unknown. So I decided to use smart flash and flash the "LG_P990_1035_21_2011-06-22", it just wouldn't flash it loads up to 50% than i get timed out error. Is there anyway to fix this issue.
Thanks.

this might be an issue with BB and RIL combination...try to install the GetRIL app from the play store and try to install a recommended RIL....reboot and check...
you can try the smartflash after trying this...
Hope this helps

Download this and use SmartFlashTool to flash this. It will unbrick your phone but beware you will lose all your data.

Download the mobile driver again, and follow the instructions correctly. Like, removing the battery, press volume down while plugging in until the s/w update screen appears, etc etc. Good luck! Hope it'll boot after the flash.

I've a similar-ish issue. I've got CWM installed and can boot into CWM ok. My problem was that I tried to install a ROM (MIUI) and the install had no errors, but when the phone was powered on it hung at the MIUI screen.
So I reverted to a backup successfully and decided to have another go (same problem). This time, after I restore to the backup (which is installed without error by CWM) I can't can't past the initial LG screen. Seems to go into reboot loop.
Any thoughts anyone? If I can get into CWM ok and have a working restore then is there something I'm doing wrong!!
thanks,
Mark
Guys,
I'm relatively new to flashing recovery and ROMs..
So, sorry if this is a noob question..

SOLUTION:
Reflash .kdz via Software Upgrade Mode (hold Power button and Volume - )
Dude, reflashing your phone should work. As long as SW mode is still accessible, your phone isn't dead yet. Follow the instructions on this post http://forum.xda-developers.com/showthread.php?p=35971349 Be freaking sure all necessary drivers are properly installed.
Or you can put your phone in recovery mode (power + vol +) and reinstall the stock rom using recovery LG tools providing your Internet connection is fast and stable

hey dude, i have flashed 7 times exactly since this morning only. and i have gotten that error 3 times of those 7. so it should not be a problem
Thanks!
After a few attempts, was able to go to the s/w upgrade mode.. (power + vol(-) )
Reflashed .kdz and it's all good.. (had to root again)
Actually, i was freaked out more coz it's my new phone and i didn't find others with the problem..
I hope that this thread would help if anyone faces a similar problem in the future..

You needed to unlock bootloader first, either "adb reboot oem-unlock" or download terminal emulator, root the phone and type:

Bootloader unlocking is only available if you're on JB. If your boot image is faulty you need to revert back to official JB.

So if I understood you right, you tried to install CWM without unlocking your boot loader? So now you got a boot image error? I'd suggest to try LG Mobile Support Tool and flash V20A/V20B and then unlock Boot loader. Even if you're on "official JB" as of now, installing CWM without unlocked bootloader screwed your boot image and there's no way to do anything without flashing back a kdz.

Hi!
I just rooted my brand new LG optimus 4x HD, and when I was going to install cyanogenmod on it, the phone stopped working. I pressed to restart in recovery and installing the rom, but when it was about to restart, it only says something like: unrecoverable boot loader, and something with kernel. I don't know what this means, but I hope there is a way to fix this, because the phone is brand new, and now I can't even start it.
Some suggestions?

ok, i'll try that in a couple of hours when I get home, Thanks everyone! I'll be back if there is another problem
in the lg pc suite that comes with the phone there is an option in "Device" for "emergency firmware recovery" this should be a relatively easy way to restore your phone if it allows you to do it without booting up otherwise use the method posted earlier. to get into the correct mode on the phone turn phone off, then whilst holding vol- plug in the usb (don't press power button) this should enter software upgrade mode.
after this you will lose root and if you unlocked your bootloader will relock it.
i used this http://forum.xda-developers.com/showthread.php?t=2256392 all in one tool to root and this http://forum.xda-developers.com/showpost.php?p=40918727&postcount=108 to unlock bootloader, you can use the all in one tool (from rooting) to install cwm after you have unlocked bootloader.

to get into S/W upgrade mode, remove battery, insert battery, hold the vol-, and plug in a usb attached to a computer (keep holding vol-).
hope this helps. also try a different pc usb port or a different cable (just to eliminate any variables)

Hi astr_x,
Do you have any example links for the respective threads you mention? I have tried adb and fastboot. I hold Volume down + plug into my computer and I get the Unrecoverable bootloader error that was mentioned above. In fact, I get this error even when I plug my phone to a normal plug (and not PC). Anyway, I connect my phone to my laptop (I always get the error mentioned) and when I type the relative adb+fastboot command in cmd (after installing all the relative drivers), I get "Error: Unknown device".
Any thoughts?
