Firmware downgrade for Xperia Tipo?

JaguarXJ — Wed, 20 Nov 2013 00:33:55 GMT

Hello there Xperia staff. I have a question for you. Recently I upgraded my Sony Xperia Tipo device to newest version. Is there a proffesional, safe, risk-free method (created by profesionalls, not freelancers) of downgrading, reverting my firmware back to older stock (without unlocking bootloader maybe), because older firmware had less bugs (which didn't really bug me). This firmware has a serious bug with media library, stock music player not responding, a lot of other users have the very same problem with their Tipo's and it doesn't seem, that anybody's going to do anything about it (like patch a fix etc.). I tried to fix the phone using SUS, used phone's built-in factory reset (maybe three times) and none of the mentioned methods helped me. After all, if I upgraded my phone's firmware in a quite easy manner (using SUS), there should be a way to do the opposite. Looking forward to your reply. Sorry for the long post.

You have 2 options

1) take it to a Sony repair center

2) use Flashtool, doing so "could" void your warranty

Hello, uliwooly thanks for the reply.

About the flashtool as a solution, you suggested - does Sony has it's own flashtool created for Xperia Tipo?

flashtool its a thirdparty program, so it could void your warranty

Third party? Is this flashtool also third party?

It's a beta flashtool for xperia devices called Emma, though it does not support tipo.

With Emma you will have to unlock your bootloader and it is Sony's software.

And by any chance, does Emma somehow support Xperia tipo, if not, is there any Sony software that supports it?
