Can't write Cert- N910T
 

So when I try to write the cert file I get ( Bypass MSL ) error even after resetting MSL..

Try version 19.1. I had a similar problem with 747.

ok so I have try that - with 19.1 and everything goes smooth
but when finishing wiping and phone reboots IMEI remains there.. no changes

Try again. Sometimes it will do it during the second attempt.

keep getting the same error ..
I was 5.0.1 same thing, updated to 5.1.1 rooted same thing
tried it with 19.1 more than 3 times and same ..
