[Q] Help! Did I screw up flashing my phone?

I have an Xperia Z1 C6903.

After updating to kitkat, I was disgusted by the new battery life, so looked up how to flash my phone back to jellybean.

I followed a guide I cannot link to in my first ten posts:
xperiafirmware.com/8-firmware/42-sony-xperia-z1-c6903
(Number 2 - flashing to 4.3).

I used the FTT linked there and the flashpro linked there.

Ran fine, here is the log: dropbox.com/s/13883t74e20b61k/flashtool_2014-04-14_06-25-39.log

After completion, I unplugged, booted phone, and now it is stuck in a reboot cycle. Seems to crash during the flare animation screen.

Please help! I've stopped the reboot cycle by running it in flash mode, then disconnecting it from the PC. As soon as I turn it on, the cycle begins again.

I'm not sure how to do this. I'm looking the update option in PCC, but this keeps asking me to turn the phone on, which I can't do. It'll only get to flash mode.

Thank you, this has made the phone functional again. Unfortunately lost messages and such, but not too bad...

I guess I'll run with kitkat a while to see if the battery issue has resolved. If it hasn't, is there a better flash file I can use, or a safer method of going back to jellybean?
