just instal back original update software by LG mobile support tool
thanks all
i knew this app from google play "OTA KEEPER", it can unroot and backs up root file easily. But i don't try it!
Anyone has experience on this app??????/:laugh:
Easiest way for unroot is with SuperSU from chainfire.
Just install the app,go to settings and choose unroot.your device will reboot and will be clean.

Hello,
I made the mistake of starting the update At&T had put out for the LG optimus g pro today and now I can't get passed CWM Recovery screen. IT won't connect to the computer even though I have the drivers installed. How would I flash back the original rom or even putting a new one on there?

Using hardware buttons the try to reboot or download mode.
Restore using the AT&T Factory TOT. I had the same issue with TWRP. Please review my thread as it will give some insight on how I recovered. As long as you can see the LG boot screen then you are safe.
Dear all,
I think, I softbricked my international e975 after installing psx rom. Now I have only TWRP, but it is not recovering my cwm backup, also, my phone is recognised as nexus4...I have only cwm back on my phone and the psx rom.zip file on my phone....I'm able to boot into twrp recovery.

Yes. Is just that for KK we need the lastets TWRP, which is not for Optimus G and we use the Nexus 4 TWRP. Or at least i think so. You can flash kdz.

Thank you atfish, davevinci and all other helpfull members, who guided me through this entire nightmare.., after 4 to 5 hours of googling, i did an adb sideload push savvyrom v3 to my phone, now everything is up and running... Thank you so much...
Just one quick question: I have my old freegee backup untouched in my internal memory. Now, to install the cwm recovery, do I have to use the old version of freegee apk again or just flashing the cwm zip through twrp will work??? Please advice and thanks a lot once again...

The freegee backup is not nessesary for anything. If your phone is running stock firmware, i recommend root it using framaroot, and unlock bootloader with freegee. This will install a recovery.
If you already have TWRP, delete script lines of CWM recovery and install it. If you dont know how to do it tell me.

Freegee backup is your efs and boot files for later use if required. Save them in dropbox or something they are very handy in bad times.
If you are already unlocked with freegee than you have a custom recovery just boot into recovery and update the recovery using zip. Like the cwm one I have posted.
Yes if you are not unlocked, use the old freegee.apk

NOW YOU CAN INSTALL CWM DIRECTLY FROM ICS
INSTALL AN UNLOCKED BOOTLOADER WITHOUT UNBRICKING​
A few months ago I found this thread on XDA :http://forum.xda-developers.com/showpost.php?p=42657066
This thread provided a way to install CWM from Jellybean V30C for the SU640 without unbricking the phone first. Now not exactly the same, the phones are close enough that it peaked my interest. Digging into it I discovered that the partition mmcblk0p7 contains the bootloader, and it was as simple as pushing the unlocked bootloader from Gingerbread to the correct partition, therefore bypassing the entire need to unbrick the phone first and thus allowing the install of CWM.
So I got brave enough and installed the P936 v10i Gingerbread ROM and used the command in ADB shell to extract the bootloader:
dd if=/dev/block/mmcblk0p7 of=/sdcard/bootloader.img. After this I restored my phone completely to stock. Rooted using the root at the above link, then ran my batch file and I had CWM no Security Error!!
The steps are simple:
Start with stock ICS (any version, carrier or phone version p93x). v20c, v20d, v20e, or v20f.
1. ROOT PHONE with the root from the above link or any method that works for you.
2. Run my batch file.
3. Install a custom ROM.
Before anyone asks me I used v 6.0.1.5 TOUCH for CWM. There are actually several reasons why. For me v 6.0.4.5 was incompatible with any ROM with kernel version 3.4. Also if I would initiate a backup from the Rom Manager app, CWM couldn't locate the backup directory.
ENJOY
:victory:
First this only is recommended for LG's Nitro HD models P930, P935 & P936. I do not recommend installing on the SU640 or LU6200.
Thnks!
Worked like a charm! (the second time lol)
I've been waiting for an easy workaround like this, you're great!
Awesome work.
Where did you get CWM 6.0.1.4? Is it the recovery.img located in the zip in the OP? I have two P930s and both have 6.0.4.5 installed. On one, I can get into recovery without a problem, the other one can't.
Thanks

May have something to do where it is stored on your C drive. Try copying the folder to the root directory on your C drive and running the batch file with administrator permissions.

With the phone off, hold down volume down and power till you get white text. Then follow the directions on the screen.

I never managed to get into recovery with the phone off. If I long press volume down with power button I get the message if I want to permanently erase everything (factory reset) and if I long press volume up with power I get into download mode.
(using lg nitro hd, cm 10.2.1, unbricked and rooted using hereric's guide, and I have latest cwm installed)

That is exactly the message that you want. Press power button twice and you will be in CWM. It says factory reset because that is what will happen if you didn't have a custom recovery installed, no worries though.

I do not remember which technique I used to root my phone, but it is rooted and currently running sphinx. Can I just flash the bootloader on my phone as is ? or do I need to revert to stock first ?

Yes you can flash directly, since it only flashes the boot loader and recovery it will not touch your ROM.

Hi dear xda members,
My phone was rooted out of the box when i purchased it via amazon, i went ahead and downloaded FreeGee and installed CWM. everything went smoothly but on the next reboot, the phone booted into recovery and i was happy to see the CWM their, but now, its stuck on recovery. No matter what i do it keeps booting into recovery.
Pushing files via ADB works, i tried to flash cm11 with ZV8 radio, but still it boots into recovery.
Did any of you guys had any experience like this ? is my device bricked ?
Thank you.
