how long does it need to reboot? the sony ericsson logo keeps on flashing for almost 30 minutes and yet to start the program. ls advise. thank you.
Alec please tell me,
what did you do?
i have the same problem
i’m begging you
So sorry to hear that, try to send it back to SE Service Centre. B4 you send it there, try to flash it back to original by using the SE Update Service. Overwrite all. As for my case, all this rooting issue has actually causes the motherboard of the phone “burn out”.I got no choice but to send it to SE service Centre. Luckily the warranty still valid.
I’m a bit confused, I’ve nevre done this before and I am worried I am going to brick my phone.
My model number is MT15i
Which package do I use?
Does this method also work with the Sony Ericsson Xperia Pro MK16A?
I’d like to know too if the xperia pro MK16A is rootable. Email me if you find a way Daniel!
That makes 3 of us. Did either of you come up with a way? Just got my Xperia Pro MK16a today and am ready for some root already!
