I have to return my handset for warranty purposes so I want to unroot/re-lock bootloader etc. The process I followed for root and unlock are in this post.
I have the stock ROM the phone came with and I have tried unrooting (which did work obviously) but I am still left with the bootloader unlocked and that warning message when the phone is switched on.
Anybody know how I can remove that and relock the device? I should probably have done that before removing root......
I would just flash back to stock with lg flash tool...

I was going to do that but I thought there might have been a way to just relock the device.

if you used freegee I think you can use restore to return to locked state

Yeah everything went well mate. Thanks for your interest
using the restore option with the freegee app just restores the last recovery you had installed before you used freegee to unlock.

This is slightly comical, but I believe he wanted to delete the old bootloader and then flash a new one. Don't think this can be fixed without a box. ODIN maybe?
Yeap bro,bcoz I can't install firmware normal way.So I flashed all partition from fastboot.Main process was to repair imei null.

Ok, but only if the device respond to command ( using USB cable ) , because I think there will be also driver issue ! If your PC cannot recognize the device, than the device is dead !
Right,my mistake was reboot command.That should be after reflashed bootloader.

Yes, thats what im thinking. Without bootloader, nothing starts and no usb drivers are loaded. Bricked .

How long ago did you buy the phone? If it was under 14 days ago then take it back as fast as possible.

Yes, you are right , but is too late !
You should make an backup before, and flash backup bootloader before : fastboot reboot !
If you still have warranty , maybe they can change it ( not sure for free .. )

Dude....i want to erase my bootloader from my Huawei Ascend P6. I want to change them with another phone using his warranty. I want to brick it. The easiest way to do that is to erase the bootloader. So how did you do that? What fastboot drivers do you used? I`m using Windows 8.1 x64. Thanks and good luck with your phone.
You're not the only one that made this mistake. Tonight I erased my bootloader on P2 and accidently tried to reboot him in recovery. And now, no led, can't turn on, nothing. When I connect it to PC it detects unknown device with some chinese words, like ㌲㔴㜶㤸. Well, I guess my phone died.

You may try 10c instead http://downloads.codefi.re/autoprime/LG/LG_G4/H815/H81510C/ ---> recovery.img
Otherwise download the kdz file here:

done that with LG UP... flashed different kinds of KDZs, no luck! Blame LG on their defective motherboard because my was manufactured in the month of May, I think G4s from October (month of manufacture) are safe from boot loop.
No one is going to chastise this guy for plotting to sell his broken phone to some poor sap? What a jackass. I hope you get hit by a camel.
Your bad luck bro. ?

Using qfil is very dangerous! If you use the wrong files your device will be converted to another!
Better try one of those sdcard methods first.
