This is the stock recovery, with some modifications made to it.
- The recovery menu is now immediately displayed, pressing volume and power buttons to access it is no longer needed
- Decreased security: Build variant set to userdebug, selinux to permissive, etc.
- Fixes to ADB: Now it's always available, and root access can be obtained with
adb root - Added "RECOVERY" label to the ENACOM logo. Note that this logo is almost never shown, only when rebooting to recovery through fastboot/ADB.
- pstore mounted at
/sys/fs/pstore. Kernel panic logs are available there
