[Android Q&A, Help & Troubleshooting] bullonwheels:
Hi,

I was trying to modify the Samsung Galaxy Young - S6312 rom in the kitchen (Android 4.1.2 JB).

I did the basic changes (root, busybox etc) and flashed it.

While flashing, I accidentally wrote the partition number wrong for boot mount and it resulted in hard brick.

Well, I am getting the phone back today from the service centre, and was wondering if anyone would take a look at the updater script, so I dont brick it again.

I corrected the mount points, to the best of my knowledge. But could you please check that and any other errors it might have?

That would be a great help.

The updater script is:

ui_print("");
ui_print("");
ui_print("Please Wait... ");
ui_print("");
