Hey guys, Hopefully somebody can help me here.

Basically i flashed & rooted my D802 to 4.4.2 using this method > [ROM][d802] Recovery Flashable d802 80220B Open EUR (rootable) - xda-developers

All was running fine however somewhere along the line something has messed up! I tried to boot into recovery and now im hit with "Secure Booting Error! Cause : boot certification verify" instead of TWRP!

Ive tried to use this method > [VDO-GUIDE] Return to Stock Firmware via OFFLINE MODE - Fixed cannot flash kdz - xda-developers to flash back to stock and unroot BUT when i get to step 5. of method 1. instead of asking to to Select Country & Language it starts the LGMobile Support Tool and the tool tells me i have the latest available software for my device.

The phone is running fine and i can get into download mode.

Thanks in advance for any help.
 
OK ive managed to boot into recovery(TWRP v2.6.3.3)I was gonna try to push a new ROM to my device via ADB sideload, When i select the ADB sideload feature TWRP just gets stuck on "Starting ADB sideload feature..." and sideload wont start!

Anybody got any ideas?

Thanks.
