So I lent the phone to my gf and she ended up rooting it to change the interface.. and now it's pretty messed up.
When I try to turn it on, it'll be at the Sony Ericsson screen (without the SE logo, just the one with letters and a blank screen) and get stuck there. It won't do anything, and will just heat the phone up as long as the battery is alive (I have to take the battery out to shut down the phone). I can't get anywhere past this screen
When I do take the battery out and try again, it's pretty much a 1% chance to get it to boot up. When it DOES boot up, sometimes it'll randomly heat up to the point where the battery will burn your hand if you leave it there for more than 5 seconds. At this point, the battery will drain insanely quick, it'll go from 100% to 0% in less than an hour. Once it's turned off, it's pretty much impossible to get it to boot up again. I still haven't been able to boot it up for 2 days now
I have tried to flash it using SEUS, using xrecovery, Global World 2.1, and numerous other methods of formatting the phone.. nothing is working. ): It flashes successfully.. because after it flashed it actually booted up and everything was set back to default. Then the battery heated up and died on me.
Any tips on what to do to fix this problem?
