Please. Dummy instruction on how to reverse an android upgrade

[Tastyboi]

Hi

I have asked this question before a while ago and all I got was a bunch of links to other messages that were outdated, Or a bunch of instructions that really you could only understand if you knew what they were talking about.

I started this post to ask for help to reverse an Android upgrade I made over a year ago to my Xperia Arc S. I was very happy with it when using it from store bought. I think it was Android version 2.3. I went onto PC Companion one day and it suggested I upgrade the Adnroid, so I did. It upgraded to version 4.0.4. This had bascially rendered my phone unusable. It was so slow that my phone calls will divert to voice mail before the disply would come up. Plus a million and one other bugs it gave.

So I am desperate to return it to a lower Android version.

I think this means I have to root the phone. I think rooting the phone means accessing the core root folder as at store bought, it is locked from accessing...

I hope someone can help. But please keep it simple, like I'm a dummy. I've seen so many info flowing around and I can not understnad it...

Rooting is all I know. Terms I've seen that I just don't understand are:

bootlegger

flash tool

ftf files

I red on one post that the flash tool is used to root the device, but then I saw on another post that if you want to use the flash tool make sure you haven't rooted the device or ever want to root the device.

So please if we could use this post as a instruction guide for dummies on how to root your device and downgrade the android version.

Btw, I have already upgrade the phone to it most up to date. So please keep any info on updating away. Unless it is needed for the requested advice.

Thanks in advance.

I am going to ask again. Please someone make this a lot easier than having to shuffle through so many threads, forums and posts. And trying to understand all the info that they go on about.

Contact your local Xperia Care and perhaps they will be able to give you "Dummy instructions" on how to downgrade

What behaviour?

Mate you aren't being helpful...

You are posting links to sites that I don't understand and links to other forums and say follow the rules and read. I read through and its too technical for me and way too much information for me to understand....

This is a Sony Support forum..

I came here for help because you ruined my phone..

I expect support, nit links to other places to get support...

[Tastyboi]

I should not have to pay extra for a service to fix a problem you guys caused...

You are clearly confused, this forum is for US, USERS, to help each other, if you want Sony to help you, you have to contact them directly

This is where PC Companion took me...

[Uliwooly]

Do contact Sony directly

So fine....

This forum is only for US users who have a high technical knowledge already?
