I cannot get TWRP on my device.

I have stock 4.4.2 aka 50020b.
Then i used ioroot25. Success.
Then I used aboot twrp v2 from Step 3.
Then when it tries to boot into recovery, it says on the device on the top

Secure Booting Error:
Device UnLock!! so Boot Success!!

Then the screen dims to 10% brightness, and after 5-10 seconds, LG logo again.
Then nothing happens, and it reboots back into main system.

Do I need to do anything else?

unplug your usb then
boot into recovery

then flash 4.4.2-v500-TWRP_2.7.0.1-recovery.zip
in twrp

that will fix your dimming issue

that secure booting error is normal

I'm currently on Mahdi ROM with TWRP 2.7.0.0. I'm planning to load up the flashable stock 4.4.2 rom. Should I upgrade to this version of TWRP before I flash the stock 4.4.2 or after? Or does it matter?

use the script from this thread scroll down to step 3 http://forum.xda-developers.com/showthread.php?t=2698267
just make sure you unplug your usb before rebooting into recovery

then after that flash 4.4.2-v500-TWRP_2.7.0.1-recovery.zip in recovery (can be found in the OP of this thread)
HI DrGravy,

the issue me (and probably the other user) is having is the system check. s the version number doesn't match the .bat throws me out with the following error

DEVICE CHECK FAILED!!
MODEL: LG-V500 FWBUILD: KOT49I.V50018a FWVER: 4.4.2

Script will now exit to avoid damage to your device!!!

Now can I simply delete the checking part of the script and let it run......

Cheers

you could try that
or just add your device to it like this:


Code:
if /I %FWBUILD%==KOT49I.V50018a (
				GOTO CheckSU
			)

I think it would work either way

Just tested v2.7.0.1 with nandroid-backup to an external 64GB exfat-formatted SD-card. Works. Thanks. :)

Upgraded by flashing the zip-file from an old version of TWRP.

Hi guys, got this device yesterday and im still trying to install TWRP. Heres my situation:

- Updated to 4.4.2 and rooted
- Installed TWRP using V50020_aboot_twrp script (found here)

After this i couldnt boot to recovery event though everything went fine, got error "Secure Booting Error: Device UnLock!! so Boot Success", after which device would boot normally so...

- Installed V50010c from OP using the same script

Now when i reboot to recovery it just shows the lg logo... cycling power boots to system as normal, so it seems theres no recovery at all now...

I have attempted booting into recovery using an app instead of adb, same deal.

Obviously without recovery acces, i cant flash according to the instructions in the OP saying i THEN need to flash 4.4.2-v500-TWRP_2.7.0.1-recovery.zip... inside is a recovery file, but the script uses a .lok file.

Help appreciated!

the first time you used the TWRP using V50020_aboot_twrp script did you unplug the usb before you tried to reboot to recovery? because you need to do that
also 50010c would not work cause the script pushes an aboot.img from 50010a

Just did it again with the wire removed and first got the secure boot error, then it suddenly booted from error to TWRP!!!

Thanks thanks thanks! Was able to flash the 2.7.0.1 from there!

My thanks once more!

Being on stock jelly bean I rooted and flashed 2700.
Being on SlimKat 4.9 I flashed LG KitKat GB version. I want back to recovery and flashed 2701 from OP. I rebooted recovery, wiped data, system, cache and dalvik. I flashed SlimKat infected 5.0 with slim gapps.
First thing I notice is screen dimming.
Should I have flashed 2701 before fishing stock LG KitKat?
Any advice for me now to get rid of screen dimming?
Do I need to flash LG stock jelly bean back? And start from this point?

Edit Monday morning:
I flashed your zip with LG 4.2.2 from the other thread. Smooth operation, no problems. It left 2701 twrp I had (there was message about flashing recovery). I let the ROM download all my apps from play (I wiped data) and rebooted to recovery. First thing I see is that on 4.2.2 bootloader twrp boots way faster than I saw on my brief experience with LG stock 4.4.2 UK version.
So back to normal, fast loading recovery.
Second, dimming is gone.

Again, thanks a million @Drgravy!
