If the process succeeds the output will stop at 47% and report adb: failed to read command: Success/No error.For me it didnt even start installing. I got a similar error (dont remeber the exact one) like "error applying update 7 kinstalldeviceopenerror " and it failed. But i didnt actually start the phone.
Tried with the recovery mentioned in this thread and also with LOS latest recovery, gor similar error. so went with the payload method.
