[XPERIA X10 Q&A, Help & Troubleshooting] DevDD:
Alright so I've been trying to Unlock my Phone's Boot Loader and Flash it using both the Flashtool 0.9.11.0 and the FlashTool 0.2.9.1-GBready_root_xRec.

Logs :

The Sony Ericsson logo pops up and then there's the charging symbol...

0.2.9.1 -

I get stuck at the Sony Ericsson logo after I unplug it and power it on and have to flash the upgrade which brings the phone back.

Any help will be highly appreciated.
