[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Derek242:
this method bricked my phone!

Xperia Mini st15i

Android 4.0.4

Firmware 4.1.B.0.587

i enabled Unknown sources usb debugging, and msc mode

i flashed the ST18i_4.1.A.0.562_kernel.ftf

(held down volume down and plugged in)

(forgot to check the "no final verification" checkbox)

then i follwed the root your pjone link you give in the guide. the root guide doesnt say turn on the phone, so i didnt. but the runme.bat didnt recognize phone. so i turned the phone on and it booted with the st18i kernel. then ran the BAT file again, and it rooted.

pulled out the battery for over ten seconds, then flashed the St15_4.1.B.0.587_Kernel.ftf.

(held down volume down and plugged in)

(forgot to check the "no final verification" checkbox)

unplugged the phone, and tried to power it on. when i tried to power it on, the light blinks green once real fast, it makes a short vibration, but wont boot.

is it bricked because it didnt check the freakin no verification box? also, after i flash a kernel, and its finished. it keeps connecting and disconnecting for the pc every 30 seconds or so.. the flashtool keeps reporting it.

here is a log:
