I havent seen this error yet. Try to convert kdz and patch it with cwm. In general section you will easily find "how-to" and there is appropriate guide how to do it on your own

sorry i wasn't home
yes as hbohd said, look for the big noob how to and convert the kdz info bin and fls

Problem with updating rooted phone

I have been using cm7 nightlies and miui for a while, but decided to get back on stock because of instabilties. So I restored a backup of stock from before I changed ROM using cwm.
Today I tried to install the newest update using the update function on the phone. It downloaded the file, but it says file corrupt...
What could be causing this?

Try to use the LG update tool on pc. This download the full Rom and install it on the phone. I think is ~400 MB.

I have now done this. Had to try 4-5 times...
Also, the Mobile support tool makes my computer VERY laggy. This sucks, LG!
To use LG update tool you need to erase CWM and restore original LG recovery. Search a bit here or on Modaco's site I've seen somewhere a zip file to do it from CWM.

It'll always work. Unbricked my p970 many time using this method

You can also try find KDZ for your firmware and try CWM injection method (http://forum.xda-developers.com/showthread.php?t=1512203) just use google to find your kdz. didnt work for me though
http://forum.xda-developers.com/showpost.php?p=22597935&postcount=3
Follow this guide and you can flash it over and over again and it will always be ready to root
What does that have to do with the V20J version that the OP asked about?????
I am also trying to root the same version for my girlfriend since she got a job at Koodo mobile and got stuck with this phone which with stock software is garbage compared to her old HTC Desire.
I've been searching for a while and not found anything to do with this software version except this post where you arrogantly told the guy to search first.
I've the same phone and the only way I managed to root and keep stock rom was downloading the v20j kdz file and following the cwm inject method. You'll have to find the kdz file, its here somewhere though
Edit: http://lg-phone-firmware.com/
Make sure phone model is selected and hit ok

I've since given up. I cannot find a working source for the UPK file to perform the CWM injection method. Also half the tutorials and download sites are in another language or converted to English making them less clear because of the translation.
Its my girlfriend's phone and she has no backup she is allowed to use at work so I don't want to risk causing it to be down for any amount of time. She will have to put up with it and bite her tongue when customers ask if she likes it, lol.

flashing only custom recovery possible ????

guyz previously i was using lg p500 and i found a method to flash only custom recovery on it.
link : ( forum.xda-developers.com/showthread.php?t=1318750 )
Now i am using lg p970 n i m away from home so no computer with me. I just want to know is it possible to flash only custom recovery on lg p970.
If any one can test ,it would be of great help to all lg p970 users.
As i did for lg p500.
we need original partition file and recovery file.
using original partition file and renaming the custom recovery file to name as original recovery file. Flashing them both from flash tool used for lg p970 should install custom recovery without any changes to other memory area.
Is this possible ?
I think "lg extract" gives us partition n other files of system. is it ??
i havent used it. but hope some one of u try if its possible.
There is a cwm inject method on noob guide in general sections stickys i think.

Yes but if im not wrong using that method whole memory gets flashed. I mean flash only cwm recovery.

Yes u can flash cwm only. Look for cwm touch somewhere here. Redy made a flash script and the corresponding package with cwm touch in it. But you definitly need root, to flash it i think.

Does this method requires a rooted device ? Will it work on unrooted devices also ?

[TOOL & HACK] unlock your SIM FOREVER (ICS & JB)

Hi guys, I understand that some of you are unhappy with this sim lock because you want to test the latest JB leak . so here i ve a solution for you.
DO IT AT YOUR OWN RISK !!!​
Precaution:
-* don't use voodoo app after using this mod or any other mod, (if you want use other mod restore your original efs file).
-** Before to update to a new build (like the coming stable JB) restore your original efs.
*, **, in the case you got the phone unlocked you can always use my mod to unlock it :good:
HOW TO UNLOCK
- First you need to backup your "EFS FILE" in safe place.
- you must be in unlocked stock firmware like BLG8 (using voodoo app + libsec-ril.so (mike1986 fix))
- unzip the attached zip "efs.zip"
- copy the files (.nv_core.bak, .nv_core.bak.md5) to your EFS file
- reboot and enjoy !!!
NOTE: applying this mod will not change your imei.
Backup & Copy & Past & Reboot ....easy
This MOD will remove the lock completely.
Don't tell me what i did because SAMSUNG ......is UNHAPPY
JUST CLICK ON THANKS
Is there something lost in translation?
"before backup this efs"
I think you mean backup efs before doing this?
