4.2.2 downgrade..

[nalab1]

Just got rid of the.total *beep*... Thats the 4.3 "upgrade " from my Z1 and lo and behold the.bluetooth problem that I had with my car audio (couldn't use the hands free facility) has disappeared! So I have proved that the 4.3 "upgrade" was complete and utter rubbish.. The.bluetooth stack in 4.3 was obviously a load of rubbish and was missing lots of functionality that was there in the 4.2.2 release...

GET IT SORTED NOW!!!!!!!!!!

I understand your frustration but please keep it in a civilized way.

Indeed this is not one of those forums that allow that kind of language, with that said, you have 2 options

1. Take it to a Sony repair center 

or 

2. use flashtool

I have downgraded the software.. as I said in my first post... What I cannot comprehend is how Sony obviously did no regression testing on this software AT ALL! Because, if.they had, the bluetooth would not have had these problems... and I, amongst others, would not have had these problems...

Anyway, you have the wrong idea of this forum, this forum is for users to help each other, if you want to complain contact Sony directly

I did.. And they informed me that it was not their fault but it was the cars fault.. When I pointed out that it worked on 4.2.2 they did not have an answer! I still say that it is Sony fault as my car audio works with no problems with a Samsung s3 that was updated to 4.3.....

Why don't you stop by a Sony repair center so you can show them that, again the point of the forum is for users to help each other not insult nor attack each other

Of course,here we are all friends and help each other,if we can.No need to insult anybody.

Nawab, how did you downgrade, sony have told me there is no official way and I need to maintain warranty...

[nalab1]

I am not attacking anyone... I am simply venting my anger/displeasure regarding the "upgrade" to 4.3.  There are several people who have also reported this problem with the 4.3 upgrade and I was simply saying that by reverting back to the 4.2.2 version it now works... and hopefully letting other users who have this problem that this course of action works....

And where exactly are the Sony repair centres?
