[Sony Xperia P, U, Sola, Go] metalshegy:
Hi, ive tried installing CM11 on Xperia P that had 6.2.A.1.100 firmware but no unlocked bootloader trough CMW beacuse i saw that some guys said to edit the script inside CM11 zip... Long story short, after CMW flashing it got bricked, first when i tried to turn it on it just vibrated one time and nothing happened and after using Flashtool and trying several firmwares downloaded trough Flashtool or from internet i always get the same error:

ERROR - Processing of system.sin finished with errors. After doing that the phone now shows "Sony" logo after powering on but still enters a bootloop while on usb and cant be turned on. When holding power button+volume up it vibrates 1 time, then one more time after about 3 seconds and then 3 times in a row after another 3 seconds. LED doesnt flash except when i connect it to USB, then its green, sometimes turning red when im using flashtool.
