I somehow bricked my OnePlus One phone badly. It only loads directly to the recovery. Pressing vol up + power button or rebooting it with adb reboot bootloader doesn't get me to the bootloader. I think I erased the bootloader partition or deleted my bootloader.
Here comes the tricky part. I can't even sideload any file or access my internal SD card because then I get either following error messages:
- E: footer is wrong
- E: signature verification failed
- Error opening '/data/media' (no such file or directory)
Right now I can either flash the OnePlusRestoreTool(64GB) recovery or the ColorOS recovery tool (both can't access the internal storage - button is not clickable). I thought I just have to mount my SD card new, but I can't enter a shell command, and most badly, I can't enter the bootloader.
How to fix it?
