Problem after flashing Sony Xperia Mini This is related to How to root the Xperia Mini ST15i.

I followed the instructions from the answer, but I'm stuck.


  Now open the flashtool again and flash the stock kernel of ST15i and
  now enjoy the rooted phone. For check if you have rooted your phone
  successful there is an app installed superuser on your phone or you
  can download the Go backup/Titanium Backup to check out its rooted or
  not.


After flashing the stock kernel, the phone is stuck with the Sony logo, and keeps on restarting. The phone can't detected by the PC, the Sony PC companion, or the Sony Ericsson Update Service. Because it can't be detected, I can't flash it. It doesn't even charge when it's connected through the charger cable.
Same problem was with me I have tried flashing by flashtool by switching off my sony ST15i and then connecting to the PC by data cable and pressing vol+ key at the same time. Your phone will glow a green light it means your phone is in flashing mode. It was sucessfull, I have tried it many times it always work.But after a month it shows no servis or emergency call I don't know what to do with it but my phone works properly but remember use only Ginger Bird ROM otherwise it may be wouldn't work.
