How to flash CWM to unlocked bootloader ICS Arc S

Hi, I have a unbranded, unlocked Arc S, running ICS, and I want to flash the 4.04 image, which comes as a CWM zip.
Everything is currently stock but rooted.
The 4.04 update is a ZIP (rather than a FTF), so I think I need CWM installed to flash the update. I can't find anything that tells me how.
I found a easy installer, but it categorically says don't use it with ICS.
HELP!!!

CWM Auto-Installer
Try CWM auto-installer, you can find it in Play Store and it worked to me.

Look in the dev section for the stock ics kernel with cwm is the simplest way.

Use fastboot to boot either a custom kernel like ArcNight or DoomKernel, or cobratos modded stock. They contain cwm, on boot repeatedly press any of the h/w keys to enter cwm and flash the zip on the sdcard.

I only ever found the old beta kernel for ICS, not the final one. Got a link?
I tried the auto CWM installer, and yes it did install onto stock ICS, and I managed to install the 4.04 ZIP, but now it just hangs on the Sony startup screen.
Any advice on how to get back to something that works?

Sorry I haven't looked at that Rom as it's a dev Rom thats been ported, before installing that Rom did you make a cwm backup? Otherwise you install another Rom.

Before flashing a ics rom in zip format you need to flash a complete ics (ftf file) via flashtool /pc companion /seus.

[Q] going from (jb) to (ics)

hi everyone i wanted to know taht i am on aokp(jb) rom and i wanna go to a stock based(ics) without using flashtool.
any help will be appreciated.

The best way is the flashtool to return to stock, otherwise a stock based kernel and ROM in the same way you flashed AOKP.
Sent from Myushi

but most of the stock based roms said that i need the 587.baseband to install the rom. please let me know coz am in no mood to use flashtool

.587 is not a baseband, it's the stock 4.0.4 ICS firmware version (fully 4.1.B.0.587 iirc). Just download and flash via flashtool

ok i just wanted to make sure if their is any other way other then flashtool thanks.

Just flash the kernel, wipe everything, and install the ICS ROM you want. I came back to ICS from CM10 without flashing stock ftf, and no issues at all.

How to go back to stock?

A few months ago I flashed xzxperience 2 rom and RaymanFX kernel, this was before official Jellybean rom from Sony was released. My bootloader is unlocked and I want to install official the Jellybean update now. I tried DooMlords rom but it wont flash.
What do i need to do? I dont think I backed up stock kernel as I cannot find it, only stock ICS rom I backed up using clockwork recovery (does that back the kernel up I wonder?)
Can I just use Sony PC companion or OTA update?
Thanks.

No, you can't use PC companion or SEUS when you have an unlocked bootloader.
Have a look in the FAQ of the XPERIA S Development forum and see if there's a ICS ftf
There should be some ICS .45 and .55 ftf files around somewhere.
I believe you can now root .55 so it should speed up your progress to an install of the pre-rooted JB ROM.
That said, DooMLoRD provided a few fastboot 'elf' kernels that you can use to get CWM recovery mode access and then flash the JB pre-rooted ROM.
Best to have all the zip files you need on your phones /sdcard before you start any process though.
If you can't flash the pre-rooted official 6.2.B.0.200 ROM, you can install a leaked version of JB, then install DoomKernel, and you should be able to install the pre-rooted official 6.2.B.0.200 ROM and then DooMKernel again. that's the long way of doing it.
I believe if you're getting a status 7 assert failed, DooMLoRD has a fix for that too, with an ICS kernel/CWM recover of some sort.
I believe there are pointers in DooMLoRDs pre-rooted JB ROM install procedure.
As an aside, I had RaymanFX GPU/CPU over-clocked kernel installed too and found it really good.

You can use EMMA tool from Sony for unlocked bootloaders to go back to stock rom or flash a .200 ftf file with flashtool.
Other option is to flash Doomloards prerooted ROM with CWM or in case you don't have CWM (or CWM on ICS kernel and errors during flashing), first flash Doomlords advanced stock kernel which includes CWM via fastboot / flashtool and than his ROM with CWM.

thanks for the replies guys, I managed to get the doom stock jb rom working in the end, followed the tips in the thread and had to flash Advance Stock Kernel with Recovery v01 (FW 6.2.B.0.200) (CWM 6.0.2.7) before I could install the rom
I will remember in future then if I want stock rom to relock the bootloader.

[Q] How to install CWM recovery in JB arc s

I just wanna know about installing CWM Recovery in my arc s with a JB rom. Because there is no supported CWM for xperia arc s for JB.
And I am new to flashing kernals..i did my arc s to JB with fusion 5.4 anyhow but if i want to change the kernal do i need to reflash the rom as well?
And also I installed CWM recovery using X-parts before unlocking bootloader. Should I continue installing like that if i Go back to ICS...or should i follow a another way since now my arc has unlocked BL.
And also when to install the kernal before or after flasing the rom.
Thank You

Recovery is built within the kernel, so you do not need to install any recovery by yourself.
You can change kernel at any time, no need to reflash the ROM. Just make sure the new one is compatible with your ROM (JB kernel with JB ROM, ICS kernel with ICS ROM).
If you have unlocked BL, you can just flash any custom kernel (all of them should include a recovery), no need for X-Parts.

Thank you for your reply
So do i need to clear any caches after flashing new kernal?
And also what is the best kernal for JB based on cm 10 for my arc s that supports 720p video recording and gives a good battery life.
Thank you

No need to clear any cache, if you change kernels.
There is currently only one JB kernel, that supports HD video recording. I will update this post, once I find it.
EDIT: LuPuS JB kernel, make sure you download the 720p version. Topic: http://forum.xda-developers.com/showthread.php?t=1885559

[Q] Xperia play Noob at installing rom.

Hi, I've had my Xperia play for a few weeks and feel like i want to install a new rom as the default 2.3.4 software is a bit sluggish. Ive already rooted and installed CWM and backed it up. I have a locked bootloader and the first instruction to installing the rom is to install a stock rom, Don't i already have that installed as i haven't installed a custom rom before? Should i just skip this step? Thanks in advance! My Model is R800i and the build is 4.0.2.A.0.42.

it depends on which kernel you want to use.
.42 firmware does not support custom partition layout, so in order to use kernel like Turbo Kernel by CosmicDan or Lupus Kernel by wedgess (both with custom partitions) you'll need to flash .62 firmware or newer, wipe userdata and system and then flash the kernel.
While this isn't needed if you want to use, for example, DoomKernel

Lol sorry didn't see you're on a locked bootloader you must unlock before you can flash any kernel

Still havent answered my question, I dont really want to unlock my bootloader if its possible to just flash the rom but do i have to flash a stock rom even though i haven't installed a custom rom before as wouldnt i already have a stock rom? The rom is a GB rom so i dont have to unlock the bootloader, it even has installation instructions for locked bootloaders.

I've said you, you should skip this if you don't want to flash any kernel with custom partition layout
But remember that if you remain on stock kernel you cannot flash no other rom than stock based ones
