[Q] Downgrade my arc s from ics to gingerbread.

I recently upgraded my arc s to ICS beta. Since it has no bluetooth wifi or the android market, i want to downgrade it back to Gingerbread. Can some one please help? ps. stupid me did not make any backup before upgrading..
Thank You.
Have you tried the Official ICS yet? Maybe it will resolve some of the issues you were having.
If you really want to downgrade though, all you have to do is flash the respective ftf file using flashtool. You'll find lots of guides/resources for this in the development section.
I dd not try the official. where can i find it? i installed beta only.
thank you.

if u are trying to say u need the .42 ftf then its in the same link, just scroll down and look for : 4.0.2.A.0.42
Generic Trade Central Europe 1 (2.3.4) (1254-2716)
india generic hardly matters as Central Europe i believe is the same as if u flash this via flash tools. then as the phone will start u will on top get the language "hindi" option aswell or india "english" .. you can root this, then update via wifi to .62 n u will still have root
if u have unlocked ur bootloader make sure u have locked it so u be able to update to .62 via wifi

[Q] [ARC Lt15i] rooted .42 FW with locked bootloader - how to upgrade to stock ICS?

Guys,
I have a Xperia LT15i with Locked Bootloader which is rooted and currently on .42 firmware.
With the new official Sony ICS update release, i'd want to move to stock ICS with latest firmware, can anyone please guide me how do i do it ??
Do I update using PC Companion or can it be done OTA ?
Also, once i update to stock firmware and stock ICS, is it still possible to root my device and keep the bootloader locked ???
I need the right advice, i am scared and dont want to end up with a bricked device...PLEASE HELPP
EDIT: I know there are lot of threads on the forum, but I am not an expert and scared to cater to this update and lose my beloved phone ...
if some one can just guide me with a step by step process, it will help a lot, it's a sincere request..!!
First of all, you can indeed upgrade!
ICS is not available through OTA, so you should go only by PCC for now.. But check if PCC shows that the update is available, because the update is available for only selective SI nos (to check your SI no remove your batrery and look in the sticker below the battery on your phone).. If PCC shows the update, then no problem!
If not, try downloading the ICS ftf file and flash using flashtool..
And for your last question, yes you can indeed root with a locked bootloader.. I'll post you the link below

Thanks a lot prasad for the reply, I found my SI number in the update list yesterday on the sony blog post.
For the rooting process, is there a better explained tutorial ? The link that you have referred is good but lot of things are just to be assumed
There is a link to the sony blog with a similar tutorial but I am not able to locate it, can you help me find it please ?

your device is unlock bootloader right? this is a flashable zip, so you can flash it in recovery mode. and i've been trying before for my xperia m Single Sim. My stock rom version is 15.4.a.1.9 and all work fine after reboot, but if your device running on deodexed firmware you have all access, but maybe bravia engine and sony theme engine can't work properly i think just try it ok. but if your bootloader is still locked you only can deodexed app, for framework i don't know it can or not, because may be bootloop and it will same happen if you try to change superusermod too, but bravia engine and sony theme engine is working properly, for Superusermod you can enable it with Serajr Xperia Xposed with that module i think you can do many customization for your xperia, you can find that file in here http://forum.xda-developers.com/showthread.php?t=2612179, or you can try download directly here http://repo.xposed.info/module/com.serajr.xperia.xposed. Have try:laugh:
