[Q] Xperia U - Stuck on logo & cant flash

Hi, I have an Xperia U, and its bootloader its locked, and recently I had followed a guide to root it with bootloader locked with flashing and everything, and it worked, but more recently i thought about updating ir to cfw 4.1.2 JB, because i had 4.0.1 and it was very slow. so i used the other guy way to install a cfw (the one where you turn on the phone and press de vol up twice while at the sony logo, to go to that sorta cmd page), to instal the 4.1.2 cfw, and when i rebooted it got stuck on the sony logo. Now most of the guides to solve this problem, tell me to flash it but i cant do it, i cant connect my phone to the flash tool it stays connected for like 15 seconds and then disconnects and goes the sony loop.
What can i do to solve this?

Same for me - try Flashtool (Google it) and reinstall the latest Firmware for your Device. Truly you selected a wrong Kernel for your Device before.

Sk17i bricked?

I need help with my SK17i, because I may have bricked it. The last ROM I installed was the Xperia Project cyanogenmod. It worked fine but I wanted to go to stock. I tried installing this: http://forum.xda-developers.com/showthread.php?t=2251685 with my CWM Recovery but after that it didnt start. After the start it shows the Xperia Project logo and then only a black screen. I can however get in the Recovery and Fastboot mode. The Sony Emma programm doesnt recognise the phone, so I dont really know what to do now. I'm a beginner but my guess is that the phone has the old wrong boot img and thats why the installed Stock ROM isnt booting. Maybe someone can help?
