Today I decided to unlock my boot loader after still experiencing lag and force closes in .201.
I wanted to backup my TA though, so after reading threads I chose DevShaft's Backup TA batch scripts, which got stuck on "INTEGRITY CHECK".
I quickly searched it up after half an hour of it stuck on this screen and found a post where it got stuck on "BACKING UP TA..." only to find that this could kill an Xperia device. I panicked, re read it and found that I was not experiencing the same problem. I checked the batch scripts for where it could get stuck at and if it could kill my phone.
I'm not sure whether it's fine, and my phone will not be bricked and I can try again or unlock the boot loader. I am on the .257 firmware.
Any ideas? The only thing I am worried about is that the command it is stuck at is running under su.
EDIT: My phone is an SIM-free, locked boot loader C5303, and am running the tool on Windows 8.1 64-bit. Reading the batch source, I have identified the place where it has got stuck on - the command to check the MD5 of the .img file on the phone. This doesn't seem to be harmful to my phone but it is plugged in the back of the PC and charging in case.
