Re: UPDATED CONTENT {GUIDE} Install ICS ( Ice Cream Sandwich) as well as root Arc S , Ray and Neo V

I have rooted and done many changes right now. So if I just repair my phone using PC companion or SUS will all the changes and rooting be undone?? Will my phone revert back to its original condition??

Once u repair u r phone will revert back to original un rooted condition. But if u face any error message from PCC or Update service, then do not worry, as Nabeel says, server is overloaded, as everybody is eating the ICE Cream and Sandwich these days.Slightly smiling Face

Re: {GUIDE} Install ICS ( Ice Cream Sandwich) as well as root Arc S , Ray and Neo V ( Downgrade to Gingerbread)

Hi Nabeel,thanks for your help to flash ICS and root. It's work very well on my phone except dialer open in long second. I don't face problem you said that required need to reinstall using SUS. Is it oke for me or there is other problem using only flashing firmware from this tread?

From yesterday I using stock fresh GB don't get any update from SONY, it says my firmware is up to date although my SI number is on the list to get upgrade. I'm from Indonesia.

And also, if I reinstall from SUS, it will download another 360MB right? or smaller? my internet not stable, afraid of failure in the middle of update

Thanks

Dialer lag is something that everyone is facing

Nopes don't worry, you can keep going with the flashtool firmware, but it is advised to repair using pcc or sus for clear installation, although there is no problem at all with the flashtool

it will download 226 MB ,,, don't worry about internet stability. Sus firsts downloads the whole firmware and then starts updating your phone. so don't worry Slightly smiling Face
