I followed the tutorial at http://xdaforums.com/showthread.php?t=2762171 to install KK ROM on my OG E977, did EXACTLY like written, but then I got stuck at boot screen telling me I have a boot security error, probably due to a locked bootloader, I guess. I try to flash the stock KDZ firmware but KDZ updater offline fix tells me battery level is low when it's not, even when the battery was fully charged.
I can't switch off the phone manually, because it starts again and gets stuck at the LG logo screen with this message:
Secure booting Error!
Cause: boot certification verify
The only way to turn the phone off is with CWM touch recovery 6.0.4.8 by LGviet (after installing the Sling KK ROM or the F180 patch, I guess, because the recovery utility was CWM 6.0.4.7 non-touch installed by FreeGee after unlocking the bootloader.). And when I turn the phone off and plug the charger, the phone boots up by itself and gets stuck at boot security error screen.
I tried to send a CyanogenMod ROM via adb sideload, but it tells me the ROM is for E975, while the phone is a F180 model.
Could someone give me a help, please? Thanks in advance.
