[Q] Recovery Broken (Secure Booting Error)
Hello, I had been using my AT&T g2 with TWRP 220.127.116.11 just fine for months but since attempting to upgrade to 18.104.22.168 (for Kit Kat) I have been unable to boot into recovery. I tried to do the automatic install as shown in http://forum.xda-developers.com/show....php?t=2472223
and began to receive a "secure booting error" upon attempting to boot to recovery, followed by what I assume to be a download mode where the screen turns black and connects as an unformatted drive to my computer. I then attempted manual install on my phone via terminal emulator as described in aforementioned thread with no luck, and have even downloaded the CWM recovery from the play store, installed that recovery, and still have the same problem with being unable to boot into recovery. I have attempted to flash the recovery file with flashify as well, to no avail.
After getting stuck at the black screen instead of a welcome recovery menu, I am able to hold down my power button, shut off my phone, and reboot into CM where everything works just fine.
I'd appreciate help as to how I might be able to restore my recovery partition. Thank you.
Edit: The exact error is "Boot Certification Verify" which appears in the upper left corner on the LG logo boot screen.
