This problem concerns the test branch:
Recovery starts normally, but the page for decryption with pin/password does not appear. After taking a look at the logs it appears that vndservicemanager starts and soon after crashes and so does gatekeeperd service. I posted below the full log.
I have no idea how to fix this error, I can"t even get a crash dump because:
crash_dump helper failed to exec

Here"s full log:

logcat.txt
