Hello Guys
I saw this custom rom ..
http://forum.xda-developers.com/showthread.php?t=1599906
so my question is if I installed this ICS custom rom
and I didn't like it can I back to the original firmware via flashtool ?
and does this custom room needs unlocked bootloader .
Thanks
If its an ICS you will need a kernel, so you will need an unlocked boot loader to flash the kernel, every time you see this rom requires this kernel, you will need an unlocked bootloader

i m new to this community and want to ask u that i have purchased a Sim Unlocked Sony Erricson Arc S..
and after using stock rom for around two months now i want to root it and install custom roms like CM9...
so i just want to ask that after rooting and installing custom rom my SIM UNLOCK remains unlocked or will it get locked again...
and i have to follow these links to root my phone (as its sim unlocked) or i have to take some precautions...???

thanx in advance
most probably your sim will remain unlocked...if not, you can re-unlock it again....
could you elaborate whether you have an unlocked bootloader....
if you have, you can directly flash a fxp120/130 kernel, boot into recovery and install cm9 directly without having to root your phone (only if your phone is already on 4.0.4)
hit thanks if i helped....

noo i dnt have unlocked bootloader... n my phone is on android 2.3...
Though you have SIM unlocked phone. you will need to unlock bootloader to install custom roms.
You can unlock the boot loader for free by following Sony walkthrough available on the web site just search unlock bootloader Sony phones in Google and follow guides very carefully.
Or you use jinx13 xda member who does this but it's a paid for service.

go thru sony bootloader unlock website.it will help you in unlocking your bootloader......(if you do it via paid service [test point method] then you will not be able to relock it again)
later download 4.0.4 and flash it on your phone using flashtool...
then, download the cm9 rom and paste it in your sd card
then, download fxp120/130 kernel and flash it on your phone
then, boot into recovery and flash cm9 with the usual steps...
check this out it is a super thread...http://forum.xda-developers.com/showthread.php?t=1653188

So I got my friends Xperia S, I wanted to flash jellybean onto the device using flashtool and the global jellybean ftf file. But before that I wanted to confirm, If after I flash the global JB ftf will I still get OTA updates? My rooting status is "Bootloader unlock allowed: yes". Please reply thanks.

yes.
I mount a prejudice currently cm10 (with unlocked bootloader), but I would like to go back to 4.0.4 Xperia, as when I bought .. I know that to do this I have to install the file. ftf from flashtool, I have to clear something to avoid having the FOTA brick unlocked bootloader? where can I find the original ftf file?
Flashtool don't need to relock bootloader. But if you want to relock bootloader, there are tutorials on this forum that show you how.

There are two different 'FlashTool's.
One is from Sony (that's not the one you want to use) and the other is Androxyde's FlashTool.
Androxyde's FlashTool allows you to flash .ftf files and also unlock and relock your BL.
