Im having custom kernal and root...
Should I have to remove them aswell...
Thanx for replying.....
Geez people, you should research before this.
Here's a thread in the General section with How to install and root: http://forum.xda-developers.com/showthread.php?t=1683957
That's for Stock ROM and Kernel.
If you wish, you can flash the ROM, then use fastboot to install a custom Kernel from the development thread which most likely will have CWM that allows you to flash RootXperia.zip and that's about it.
Unlocked bootloader makes everything easier.

I recomend u flash a stock GB firmware first, for example firmware .42, and then u relock the bootloder. After that, update, and the unlock the bootloader again

If you have an unlocked bootloader, why not just flash the 4.0.4 ICS using Flashtool? There's no point in locking your bootloader, then updating and again unlocking it.
Just flashing the .ftf is much simpler and doesn't waste your time.

You cannot update by SEUS or OTA with an unlocked bootloader.. Why don't u simply flash the latest ROM?
If u want SE updates.. You'll have to Relock bootloader (check Namaste guide thread for it) with stock ROM (2.3.2) .. root .. then update OTA (Again check the Namaste guide thread for this too)
Note: Root does not need unlocked bootloader..
thanks Bro.
i have relock the bootloader.
and update into 2.3.3....
if i want to root,then i have to downgrade to 2.3.2 then update it into 2.3.3?

So I've finally decided to unlock my bootloader so I've been reading a few threads about it but I want to be sure that I'll do it right.
I want to use this method:
http://forum.xda-developers.com/showthread.php?p=12873655
But since I'm on a branded phone I understood that I'll have to flash a generic Rom first to allow the unlocking to be done, am I correct?
I do understand that I'll lose the DRM's and stuff and that while on an unlocked bootloader I cannot use official SE programs (PCC & SEUS) because it will brick the phone correct?
After the unlocking is done I'll still have a fw installed right?
And finally, after unlocking bootloader I'll flash roms in flash mode and kernels and baseband on flashboot mode right?
Thanks for the help guys!

hiii developers
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

Is your boatloader unlocked?
Sent from my Neo V using xda-developers app
The "root" in flashtool refers to the bootloader. In this case if yout bootloader is "not rooted" then that means you have a locked bootloader. Unlock your bootloader if you want to flash custom kernels.

i need android sdk to unlock boot loader
i cannt download it from google site in our country
anyboady can upload android sdk to me ???
So I have the Trinity Rom installed, unlocked bootloader, trinity x kernel and a rooted Xperia S. I want to go back to the beginning, to start everything from scratch. Can someone tell me a step by step procedure to revert to the old system because the PC Companion won't repair it because of the custom firmware.
Thanks!
Download and install Emma(the sony developers tool). That can reflash your phone to stock firmware. Or flash an ftf though Flashtool.
Also, there is a sop on the xda website regarding relocking the bootloader if you want to do that.

I have flashed the stock kernel somehow and relocked the bootloader while still having the custom rom, I knew that my phone wouldn't go past the sony logo, because when I was installing the rom I chose bootloader unlocked so now I can't win either way. What should I do, still install emma?

OMFG, what were you trying to accomplish by those actions? Why relock bootloader? Only thing you had to do is to flash prefered FW via Flashtool.
