This works on all Canadian variants of the lg optimus g 2600 lte phones.
If you root you can not OTA update.
If you root and flash to any version of jellybean OTA= over the air update is no longer needed.
I AM NOT RESPONSIBLE IF YOU ERASE YOU FAMILY HISTORY OR REMOVE YOURSELF FROM THE GENE-POOL
I did not develop or create this i just merged it so it would work.
USB debugging must be turned on found in settings then development check-mark USB debugging then plug in you phone LG drivers must be installed found here http://www.mediafire.com/download.php?3p6u1bq776bdbzi
If you have issues with getting in to recovery i did try QUICKBOOT found here http://www.mediafire.com/download.php?g4g37gwd6y99urb or download from Google play
1. Download: lg e971.zip http://d-h.st/HsU
2. Extract it
Update not tested i have added the files to e971.zip or download the the ZV9-ZVB-Universal-Root Posted by fiddy619 http://forum.xda-developers.com/show....php?t=2181103
ZV9-ZVB-Universal-Root Update run CurrentRoot.bat first if it works go to freegee.bat then continue to step 8.
3. Run: RunMe.bat ignore restore instructions skip with back button
4. Run: Root.bat
5. Download busybox from the market and install it then run it
6. Transfer: cwm6027touch_v14.4.6_geebus.zip in the found LG e971 folder to your internal SD-card not in a folder in main directory.
7. Run: Freegee.bat once complete you are now ROOTED with CUSTOM RECOVERY
NOTE: This CUSTOM RECOVERY DOSE NOT WORK WELL AT ALL continuing with next step to update the custom recovery.
NOTE: To enter custom recovery shut phone off then press vol up+down+power at the same time you will see fastboot hit vol down twice you won't see anything happen on the fastboot screen hit power it will reboot to custom recovery.
8. Install zip from internal SD-card look for cwm6027touch_v14.4.6_geebus.zip in your main directory then flash it.
Now you can flash ANY Stock 4.1.2 ROM OR 4.01 ROM
Recommendation for Rogers use this Stock 4.1.2 Jelly Bean LG-E973/1/5/0 Canada / At&t / Int'l Edition found here http://forum.xda-developers.com/show....php?t=2127346 Thank houstonn for this if you want to donate http://forum.xda-developers.com/dona....php?u=4852479
UPDATE: CM10 based roms will boot loop or just not boot due to a partition issue you must downgrade to shipped revision d not e kdz then full root/boot loader unlock then flash what you want.
FYI I bricked my phone once then restored it just to get this done.
After 10 hrs of playing around with all i could find in the forums i found this to work.
I have repeated these steps on 3 more phones for other owners and it works great.
Now i have no bloatware removed LG-Ui removed LG Email and Google Mail using enhanced email for faster push intervals Full nova launcher custom kernel and pimped with pimp my ROM for added tweaks and flashed g-now
IF YOU BRICKED OR WISH TO RESTORE OR DOWNGRADE
NEEDED FOR ANY CM10-ASOP/AOKP ROMS
E97110D_00.KDZ downgrade here http://www.mediafire.com/download.php?rhe7im3hbznow5t
NEEDED FOR ANY JELLY 4.1.2 ROMS
E97110E_00.KDZ O.T.A. update here http://www.mediafire.com/download.php?rkyevf6rrmypdwr
Put your Optimus G into Download Mode by switching it off, attaching the usb cable to the phone, holding both the up and down volume buttons at the same time and lastly inserting the usb cable into the computer; wait for the drivers to finish loading if doing it for the first time.
Run KDZ_FW_UPD.exe. Use the settings below
Phone Mode: CS_Emergency
Navigate to the folder which you have saved the downloaded KDZ file
Click Launch Software Update and wait for the flash process to finish
Your phone will restart itself when complete
If you get stuck on the lg logo perform a factory reset volume down power at the same time release power at logo hold volume until you see factory reset then power twice
This proses is the same for downgrade E97110D_00.kdz is the downgrade file and is necessary to flash and run any CM10 based rom because of partition settings and if you downgrade root and fregee is all that you need and i recommend the downgrade its more compatible with custom roms
