My LG E975 doesn't boot anymore after I tried to install CWM (220.127.116.11) with the help of ROM Manager (Method 1A from these instructions). I get stucked at the
reboot into the stock recovery part and now the device doesn't work anymore. I get the message
Secure booting Error! Cause: boot certification verifiy
The available options are hard reset and the download mode. Recovery mode (
in FastBoot mode press 2x Volume Down and than Power) doesn't work because the device doesn't get in the fast boot mode (
Volume Up + Power). Safe mode (
Power + Menu button) also doesn't work. Because I wan't to access the files (apps, data, ...) on the phone I thought if there is a possibility to copy the files if I'm in download mode? Or is there another way to access the data?
PS: Has this problem happened because the bootloader was not unlocked?
