Ok so, I really messed up my phone, which is actually pretty new... In an attempt to install Android 2.3 I rooted, installed xRecovery and Busybox. After istalling the wrong ROM by accident my phone kept on booting and rebooting after starting screen... Then I kept MD5 mismatch errors and I decided to clean up the phone formatting it all, everything went OK until I chose to format SD card... The xRecovery froze and after 30 mins like that to format a 1.8 GB SD card I decided to take off the battery (Bad idea). Now everything I turn it on it freezes on the "Sony Ericsson" screen and even If I press back key, xRecovery wont start and it just freeze there and nothing else happens. I tried taking off the SD card, trying to update it from PC using USB but PC won't see it because it doesn't even let me start it. I have no idea of what to do, and there are no places on my city were I could take it to technical support. If someone who is associated which this kind of errors could help me or give me a tip it would be REALLY helpful. Thanks.
