Hello,
Sure i want to help you,it was a lot of searching on the internet,en a lot of "hit and mis" trying :laugh:
for me this helped me just fine,but maybe other more experiences users do it another way...
First backup everything you dont want to loose.
I have first installed Flashtool 09.9.0 here is a link; http://androxyde.github.com/
then i have searched for the Android gingerbread 2.3 ftf file. (its a bout 250mb big unzipped or 500 mb unzipped)
here a download location where you can download the file: https://rapidshare.com/#!download|271|2005005665|st27i_6.0.B.3.184_CE_ftf.rar|270851
and choose "save file to your computer")
Then put that downloaded file in your flashtool folder (normally this is: c/flashtool/ ...and put it in the folder "firmwire")
Then connect your x peria go with usb connection to your computer.
open flashtool and choose the "flash" icon.
then choose "flash mode" and then normally the right file is already selected ( 'st 27i-60b184 etc...) if not you have to choose it manually
(c/flashtool/firmwire..) then hit the "ok" button and of you go!
Just follow further instructions very secure (be sure you follow it correctly, for example ress volume down button,connect/disconnect the usb cable etc...) if you are doing in nog right it will not work.
I hope it helps you :good:
Greetings,
Phil

Thank you very much but another question, is this for the st27i (note the "i") or for the st27a, cause i read that they use different 3g freq, another thing is this global or locked to a specific region? (im in mexico so i want to make sure that it will work) because when i flashed to ics 3g didnt work, and the guy that works for my carrier company made me the favor to change its freq or someting so that the 3g's phone worked but im pretty sure that he wont do it again lol thank you in advance

there's no such problems i used MT15a firmware on my MT15i.... they use the same baseband so dont worry
Sent from my MT15i using xda app-developers app

Hi,
Hmmm that is a trickky question.
I am located in europe (belgium) for me everything works fine,but for mexico i really don't know...
I schould say give it a go...and if it dont work put back android 4.0 (or whatever is on your phone)
putting back android 4 is the same as i described to put android 2.3 back on it with flashtool...
and if im correct you can let the software do that (that came with your phone) from sony itself to get the update to android 4.0
Greetingsn
Phil

Hello,
Well i thought my phone was working fine now (and it does)
but like you say my 3 G for internetting also do not work....
At home i go on the internet via Wifi and thats works fin,but today i tested my 3G connection for internetting and indeed it dont work...
You think it is the fault from a wrong ftf file "st27i"?
Hmmmm in dont know what region uses the correct file,so if somebody knows where to find that,feel free to help
But if 3 g dont work overhere in europe the chacne is big it works fine at your place...

EDIT:I just called my provider and it was only a matter of selecting some internet options on my phone.
so that i had no 3G had nothing to do with a bad firmwire from another country.
They think this firmwire should work everywhere,its more a matter op selecting the right options on your phone...
hope this helped...
greetings,
Phil

what were the configurations that you had to do in order to solve 3G's problem?

Wel i went to the website from my operator here in Belgium and for each phone they have put all the correct settings on their site step by step,very easy...
For example my "sony xperia go" it is this page: http://klantenservice.telenet.be/mo.../st27i-xperia-go/internet/handmatig-instellen
then you see on the rightdown side "Volgende" klik there a few times on and you see what steps i had to take to get my ineternet
working with 3G.
Offcourse these settings will maybe nog suit your phone in your country,but then you see what pages you must change to get 3G working.
Only the settings will change but it is the same pages/menu on your phone
Best is to contact your operator and ask what settings must be done

Hi, i know its been a while, but i just wanted to let you know that the reason why i didnt had 3g was not because of the baseband changed, the reason is because i didnt had the APN of my carrier... i know that is reaaly noob but it was my bad... just in case this is useful to someone else
