Hey guys, could anyone of you give me a full partitiontable of our P760, because I d like to take a ,img backup via the dd command of all partitions, before I try to unlock my BL or anythingbelse. It simply always is good, to have a backup of everything, just in case
Thanks in advance.

Well I did it manually I backed up xloader and u boot before and after but is it really possible, to relock the phone with those files? Anyone who tried it already? And yes I was able to unlock. It came with JB v20c preinstalled, I then rooted with the LGpawn app, installed all drivers, set it to lg software mode, waited for 30 minutes, rebooted via fastboot oem-unlock command, pushed vol up and voila lets see, how long this ROM is able to last on my phone

No it's not possible to relock the phone, Dump your current xloader and uboot and compare to backups and you will see that they are identical.
Omap4430 bootloader security is an efuse based, uboot only reads it's state.

Not sure in your case, but I'm guessing if you fastboot flash a u-boot from ice cream or a u-boot.img from a kdz that is not unlockable, It will temporarily lock your device ( will receive the lg security error), if you flash a custom recovery or boot IMG.
That is the case with the p769 version
If I'm not mistaken the x-loader is never changed. I could be wrong, I need to perform a md5 sum check on the x before and after flashing a new kdz, to be 100% sure

Lelus said somewhere that only some carriers allow unlocking bootloader, trust me it s true, I tried unlocking on various firmwares, every time phone just reboots. I was finally able to unlock on v20A indian. But others were successful in unlocking on firmwares on which I was unsuccessful. And some waited for over 11hours and then they were able to unlock. So give a try once more. :thumbup:

I have the p769 with v20f and I have not been able to find a way too unlock my bootloader either. Help would be much appreciated.
I think the problem for some, is that the u-boot is not getting replaced while performing the offline flash. Try extracting the u-boot from the kdz and flash with fastboot to the system.
Run offline flash of 20b kdz and when the phone boots up, turn it back off and flash the u-boot you extracted from 20b, then wait 30 min (I waited longer) and try.

Okay, before you do "adb reboot oem-unlock", move "Android" folder from your sdcard0 to your C: drive. Then open command prompt and type "cd c:/Android" after that type adb reboot oem-unlock.

I copied Android from sdcard to C:/ but theres nothing there, i mean adb etc. Take a look:
I need to move adb files to this folder?
So i finally unlocked my bootloader on my p769. After i unlocked it i went to recovery and restored my backup to a 20F T-mobile P769 rom (yes i know this was stupid, I should have installed recovery via fastboot while I had it open). My touch screen is borked and I have no recovery set up.
Things I've tried:
To turn on USB debugging, the backup i restored does not have a homescreen so I cannot access the settings to turn it on.
The KDZ offline flash method, but it always stops at 15% even though i've uninstalled and reinstalled the drivers countless times.
"Upgrade recovery" via the LG software tool. It gets to the part where it downloads the file and even after 2 hours it doesn't download. My hosts file did not have LGs IP when i tried this.
Is there something I'm doing wrong? Is there a button combination to force my phone to go to fastboot mode? Or can i got from s/w upgrade mode to fastboot mode? This is really frustrating.
Alright so i managed to turn USB debugging on, but i have no root or recovery. Is there anything I can do from here?
EDIT: managed to get root and installed busybox the correct busybox. i can't seem to get the recovery to install though (im using the l9 recovery installer APK. It says the recovery is installed but it won't reboot into recovery and the LEDs dont flash when i power on the phone). My phones touchscreen is still borked.
That LG software tool never worked for me and I never used it. Find a kdz uploaded and keep the phone on. No sw mode. I've been reading a lot of stuff on here about u boot and adb. . .never did any of that with other phones but I haven't bricked this one either to test any methods. I'm rambling. . .let need know what happens.

Even if your bootloader is unlocked you still have to install a ROM that is made for your phone. Just go to backup/restore then restore from sd and pick your backup. Good luck!

I never seen that error, but I would try to offline flash a kdz. Offline flash will remove any changes to the system.img and should not touch your data. However, you are probably on a jellybean kdz, so you will need to use fastboot, and flash ice x & u for it to work. Or use the longer method Lg Mobile Recovery tool (this takes longer because it will have to download the kdz from lg). If you use the recovery tool remove any changes to your host file in windows.

This generally works, i mean it worked for everyone
Just connect phone put it in usb debugging and software mode and run commands..
Btw try wiping data and cache.
Uninstall and then install every lg driver but first delete every folder left behind and if nothing works flash the v20b or v20c kdz and try again...
