Then it won't do anything.
IMEI is still same after manually reboot.
Am I doing something wrong?

I also intentionally inserted XXXX at cert file for posting. Real operation had real numbers in it.


Any advice or help will be appreciated.

Unfortunately I do not have security backup and I reflashed phone with 5.1.1 then rooted the phone with CF Auto Root
I repeated "write Cert" Operation

This is the result.

This time at least writing certificate actually tried to write then failed.
I am not sure if error is coming from there are no serial number or IMEI on the phone now.

Any idea how to get the phone back to original state without backup file?

Or am I just SOL?

I got security off of another sm-n920t then wrote that security to this phone. Then reflashed stock firmware. After that I rooted with CF Auto Root then performed drk repair. Drk repair succeeded. Then I wrote the cert and everything went well. I am not exactly sure why suddenly it worked but it is solved. Thank you very much for your support
