No I didn't do any reset. I thought it was encryption as I never saw password prompt before. I guess if you don't set password protections on device, there should be no prompt. I did check the modded boot.img before I made changes and the version on my device are matched. There may be something wrong with the su script that changes device behavior.
Can you validate in diagnosis mode the following file exists in /system parition?
first mount partition `/dev/mmcblk0p9` and assuming mount point is `/mnt/Lucifer/` then:
And oh I did find a small bug in the script: you should `mv /mnt/Lucifer/bin/.ext/su /mnt/Lucifer/bin/.ext/.su`
I find where your problem could be. It shall miss file `/mnt/Lucifer/bin/app_process` and `/mnt/Lucifer/bin/app_process_init` due to some bugs I had in the script. Sorry about that. I'll write you a step-by-step guide to fix it.
I just copied the latest official FwUpdater.pkg to my device and ran it with start_eufwupdater.sh. It booted fine to the setup screen after that, so at least I know that as long as I can boot into diag I can recover it.
Another thing I have found is that if you're in diag and run /usr/local/bin/mass_storage, it'll mount as a mass storage device to your PC. Copying files that way is much faster than through serial. Then eject, ctrl-c,
mount /dev/mmcblk0p16 /mnt/sd
