My LG Optimus G E975 is stuck in CWM based recovery.
I can't get the phone in download-mode by pressing UP-power.
When using adb reboot download it reboots to CWM again.
The problem started when I updated CM12 nightly in the systemsettings.
The phone got unuseable due to system-errors, so the only thing I could think of was restore to an old backup (unfortunaly from march last year)
After some tries and many error's I now got the Secure booting error. Device UnLock!!, so Boot Success!! and goes to recovery.
How can I restore my phone from this using adb? Fastboot isn't working...
