I had unlocked the bootloader of my p768 sometime back by flashing onto a p760 firmware and then i returned back to a nandroid backup of my p768 v20A
With the nandroid restore, I got my old recovery back(the one which is installed by the l9 recovery installer app) and everything normal
I wanted to use the touch recovery which is in this thread.
So i replaced the recovery in my nandroid backup with this one and tried to do an advanced restore of boot.
Now I have a security error.
Isnt the error only locked bootloader specific?
Update--I used the LG flashing application. I had to use the recovery phone option to make it work. It flashed V20A on my phone. When I did the bootloader unlock check in the hidden service menu(3845#*768#) it said "lock"
but now when my phone is in SW Update mode, it says bootloader status:unlocked

Im trying to flash kdz to lg p769 to unbrick it, i get this error
how do i fix this? please help
So you have already installed JB before, and is now soft bricked (not able to boot)? In that case, the only option is to fastboot, and use fastboot to write back ICS U-boot and X-loader.
Follow this link: http://forum.xda-developers.com/showpost.php?p=41768774&postcount=1
After you are done with this, you should be able to flash kdz again.
Hey Guys!
I'm currently having an issue i would like to share:
I'm trying to fix my brother's phone, is an LG P768. He tried to root it (first time ever) and apparently he flashed wrong Xloader and Uboot. The phone still works but i am unable to access SW Download mode or Fastboot (Required for Flash stock rom again). I've read many threads where you can flash those files again but the same issue I need to flash them via Fastboot or SW Download mode. obviously i need to install the drivers in my computer to do this procedure but there is no way to install them if my phone doesn't boot properly into those modes.
Model: LG p768
KDZ File: v20a_00
4.1.2 Stock Rom
Hopefully someone can help me.
thanks

Ignore all errors. Just start the flashing process and DO NOT touch anything.
If you just want to have rooted KK, follow this guide. No need to downgrade to JB if you want root. Just make sure you flash the latest twrp after you flash the pre-rooted kdz.
Second problem

Don't quite understand. If you haven't factory reset your phone, then you should still have TWRP. Boot to TWRP with fastboot commands or button dance?

How could you not be familiar with lgup? You HAVE to use lgup to convert your h930 to us998 to even unlock your bootloader

Europe H930 doesn't convert to North America US998 for bootloader unlock, among other reasons as it already has fastboot flash commands.
But he probably used LGUP to downgrade to necessary pre-July 2018 H930 KDZ firmware -- unless he was lucky enough to already have that on his phone.... Those of us in the beginning of WTF didn't have to downgrade to anything.
There's also dev patched LGUP in the Europe H930 KDZ thread. He's had to have seen it...

Something is messed up about your phone. You need to go back to the beginning. Reflash stock H930 KDZ.
Then, we'll worry about reinstalling TWRP.

See bottom of post #1 in this thread:
https://forum.xda-developers.com/lg-v30/development/h930-lg-v30-european-market-h930-t3779076
Unless you were already on pre-July 2018 firmware when you unlocked your bootloader, you had to use LGUP to temporarily downgrade earlier firmware. Since your bootloader is already unlocked you don't have to downgrade, but you do have to re-flash stock firmware with LGUP. It can be the most recent, if you wish. Then you will use fastboot flash commands to re-install TWRP.

Yes. You can either choose Refurbish or DL Partition (but choose all partitions). This will wipe your phone, so save off anything you don't have stored elsewhere. Your bootloader will remain unlocked. You will then reinstall TWRP via fastboot flash commands.

If you choose "upgrade" it will only overwrite the parts it thinks needs updating. I think you need a fresh install of all the stock firmware as something seems corrupted from your ROM installation.
Since your bootloader is already unlocked, you can actually flash the newest H930 firmware. 20R is sort old. I think 21O is the newest... But it's your choice.
Then, you would reinstall TWRP, reflash the no root check and no encryption files, and reflash Magisk -- like when you first unlocked the bootloader and rooted.
