LG THRIVE EMERGENCY MODE/BRICK FIX/REVERT TO STOCK v11H Firmware/How to root after unbrick & revert/install CWM

***I want to make a few things completely clear:

1. THIS IS FOR THE LG THRIVE (P506GO) ONLY.

2. I AM NOT RESPONSIBLE FOR FURTHER BRICKING OF YOUR DEVICE (however I have not had any issues and I have done this many times)

3. I do not know where I found this procedure originally, however I have seen it posted around the web a few times. So I cannot actually give credit to anyone because I do not know who i got it from or who came up with it originally, So I apologize.

4. I did not make any of the files.

5. I did this because I am sure there are other people that have spent hours, upon hours, upon hours trying to figure this out, and my wife drives me nuts and I figure other spouces have been driven nuts, so here you go. If you like it, use it, if you dont, then dont.

This procedure will work for ANY LG THRIVE THAT STILL COMES UP IN EMERGENCY MODE, If your phone shows up as a QCUSB_DLOAD or something to that effect in device manager this will not work, This will also work for anyone wanting to fully revert back to stock 2.2.2 v11H. This is also safe to the effect it will not mess up your NV partition (there is another unbrick guide that you run the risk of screwing up your NV and then you wont have cell service after the unbrick).

That being said on with how to do it!

Download these files first

CUSTOM KDZ v11h

LGUnitedMobileDriver_S4981MAN38AP22_ML_WHQL_Ver_3.8.1.exe

LG_KDZ_FW-Update_OfflineFix

Unbrick Solution

1. If your phone is plugged in to the comp, unplug it. Remove the back off the phone and remove battery, do not worry it will be fine. Now set it to the side, we don't need it just yet.

2. Install the LG UNITED MOBILE DRIVER from the file you downloaded.

3. WE ARE NOT INSTALLING ANYTHING ON THIS NEXT STEP THIS IS MERELY TO HELP US ELIMINATE A PROBLEM. If your phone automatically boots into emergency mode then go ahead and plug it in (for those stuck in bootloop or just wanting to revert press and hold back + Volume up and then plug in the usb) and let the drivers install. Once that is done go to Device Manager (Start->run-> type devmgmt.msc and press enter.) expand the modems section and disable (DO NOT UNINSTALL) the LGE USB MODEM (See pic below). It will ask you to restart your computer, DONT.

4. Disconnect the phone from the computer.

5. Extract the contents of the LG_KDZ_FW-Update_OfflineFix to it's own folder.

6. open the folder to which you extracted those files then open the KDZ_FW_UPD_EN folder

7. XP Users: just double click the KDZ_FW_UPD.exe/Vista,7,8 users right click and run as administrator.

8. Set Type to 3GQCT and PhoneMode to Emergency (others tell you to set it to diag, dont.)

9. Click the little folder with the curved arrow above it to the right of the KDZ file and select the custom_lg_thrive.kdz file you downloaded earlier. Leave the program open.

10 EVERYONE MUST DO THIS STEP EXACTLY WHETHER YOU BOOT AUTOMATICALY INTO EMERGENCY OR NOT! Plug your battery back in, then press and hold the back button + Volume Up + Power. Release ONLY POWER once the thrive starts and then release back and volume up once your in emergency.

11. NOW PLUG YOUR PHONE BACK INTO THE USB!

12. Hit Launch Software update. If it says phone isnt found, first verify the LGE MODEM driver in device manager is still disabled, if it is disconnect phone and then plug it back in without rebooting and hit start upgrade again, it should work this time. IF THE WINDOW FREEZES DO NOT PANIC IF IT GIVES YOU A MESSAGE SAYING ITS FROZEN CLICK WAIT on VISTA/7/8 (on xp it should just revert back, once it does youll see in the dialog box it is flashing let it continue until it says it is complete (Your phone will reboot and you will be at the battery charging screen)

13. WE ARE NOT DONE JUST YET! Now we have to do a Factory(Hard) Reset SO with the device off press and hold the home + volume up + power. release all three once the device boots, let it do its thing. when the device reboots, it will seem to take forever. but it will finally get to the Android setup screen.

Walaa You are back to v11H stock firmware.

How to root after unbrick/revert to stock

1. After you setup your thrive go to settings->Applications and check unknown sources

2. in the same menu click on development and check all three settings in there.

3. Make it easy on yourself and just use the phone browser to come to this thread even easier here is a bit.ly link: http://bit.ly/14EbsSF

4. from your phone browser download the gingerbreak attachment.

5. Install it after its downloaded (if given the unknown sources dialog box refer to step 1

6. Hit Root Device, and let it do its thing, after it reboots, it will be rooted.

Install CWM

1. After rooting via the steps above, open up the play store.

2. In search type Rom Manager and install the Rom Manager from Clockworkmod

3. Open up rom manager and it should prompt you to install Clockworkmod Recovery. Click continue OR click the Flash Recovery button, it will search for your device, but it will pop up for the P500 (old Baseband) SELECT THAT ONE! then click normal install.

4. once it says it is successful go ahead and reboot into recovery via the menu in Rom Manager (allow superuser permissions), to verify that clockworkmod is installed. IT WILL HAVE MESSED UP COLORS, and may come up in the dialog box that an error occurred, THAT IS EXPECTED AND IS OKAY. Use the volume keys to navigate, power to select, and the back key to go back.

There, from this point you should be able to do whatever you want to your thrive that you want. I hope this helps.
