Modified Software Can't be repaired or updated

[#1]

I have installed the latest PCC & SU in my laptop and connected my phone as per the instruction. When i click on the repair phone due to Battery Dained out quickly issue, the PCC or the SU is saying "Modified Software cant be repaired or updated".

As per the given instruction in blog i have unlocked the Bootloader but didnt rooted my phone. I am not sure when i havent touched anything in my phone except the Bootloader, why PCC cant repair the phone keeping the bootloader unlocked or change the bootloader locked again to original Factory Settings?

Thanks,

The post is saying to use the X10 flash file. will that work with my Xperia Pro?

Also, do i need to reinstall my OS and apps again for re blocking my phone?

Yes the file will work and you don't need to install your OS after relocking
