Boot Certification Error for TWRP?
I cannot figure out for the life of me why I cannot install TWRP on my rooted 4.4.2 ATT D800 LG G2. I'm gonna ask some pretty dumb questions because I feel like I'm missing something here.
I installed TWRP2 custom recovery onto my rooted D800 ATT G2, via the "dd" method using adb on computer. All of the pushing and loki stuff worked, but when I boot into recovery, I get a "Secure boot error" and "Boot certificiation verify" error, then I reboot the phone again and it turns back on like normal. I really want to flash the volume boost onto my device but I cannot without a custom recovery.
I've done hours and hours of research and I cannot figure this out.
Thanks in advance.
