Brazilian Case - Sony Tablet S (SGPT131BR/S)

[MLRamos]

Hello!

My tablet is not rooted. I am trying to download an earlier official version or equal to the current (4.1.1 release 2) by Windows because the wifi just stopped working.

I downloaded the following files: (Brazil)

ICSR5A
info.update.sony.net/ST002/nbx03_045/contents/0003/signed-nbx03_045-ota-121116105.zip

ICS Release 1a
info.update.sony.net/ST002/nbx03_045/contents/0002/signed-nbx03_045-ota-120804014.zip

However, after downloading them, I can not unpack them due error. I'm downloading by Windows, is that the problem?
I have a Sony Tablet S (SGPT131BR / S) and the current version of Android (4.1.1r2) are only connecting on shared WiFi and there are no modems or routers direct. So I want to go back to the ICS and redo the upadte to Jelly Bean or download the same version directly.

I should just rename the file extension? .ROM .apk?

Any tips?
Grateful

Maybe it was not clear: I would downgrade to the first version (factory)!

Errors ...

My gadget is no wifi. I'm downloading the zip file indicated by Windows and am subsequently transferring to the SD card tablet.
I have tested unzip the files by Windows (PC) and Android (in Tablet) and both give errors.
Where am I going wrong?

I believe that today, all links to the ROMs are broken unfortunately. I even made a collection of them, and yet, none is "ok".
Intending to correct a problem with wifi, I ended up almost bricked my gadget: it on / off, accepts access to recovery screen, but is looped in the language of screens and following ... = (
I believe that the solution to it would be only through the ZIP file via SD Card ... thank any contribution of personal collections. Grateful.
