Downgrade from 4.3 to 4.2

Hello!
In Slovenia I wanted to sell my phone. I have updated it about six months ago to 4.3 with Sony PC Companion. My customer wants me to downgrade it to factory version, which I think it was 4.2???

Is there a way to do this with Sony PC Companion?

Thank you very much

Re: Downgrade from 4.3 to 4.2

It's not possible to downgrade the phones software using PC Companion. But which software your phone was delivered with depends on when it was made so there not one single factory version.

The first software for Xperia M was Android 4.1 but i'm not sure why your customer would want it downgraded to that version?

@tadejkoball

If you have single sim then first version was 4.1. But if you have Dual sim, then first version was 4.2.
You can't downgrade using Sony PC Companion.
However, you can download .ftf file of Xperia M Dual sim, and flash it using Flashtool.

Re: Downgrade from 4.3 to 4.2

I have a Sony Xperia M dual (C2004). I updated it to Android 4.3, but I have had problems. Randomly, the speakerphone is activated by initiating a call and music stutters. Can I return it to the original version of Android?

That process already did , but problems persist. Is there a way to downgrade safely and without risk ?

Hi @jeffrey83

 

Could you try boot your device on Safe mode and see if the issue persists:

I hope can be useful.

 

I'm at disposal for any question.
