An xperia S. Locked bootloader but rooted with cwm installed.
Stock gingerbread firmware installed
If i downloaded a pre rooted zip file of ICS stock firmware and flashed via cwm would it work?
As in can cwm flash the kernel/boot.img even if the bootloader is locked but the kernel/boot.img is still stock sony?

If you want flash stock ICS when you are on GB, you MUST be on ICS first. Then you can flash ICS with CWM.
You can't flash stock kernel with CWM. You should use flashtool to do this.

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.
Please guide me after update of firmware to 6.1.A.2.452 I will loose root?.Can I flash another firmware for stock custom rom via flashtool without unlocked bootloader?.Can I unlock my bootloader after the update?Which is the best stock custom rom and other custom rom which is easy to install & better than stock rom
Rooted 4.0.4 rom with locked bootloader
6.1.A.0.452

Something easy is flash your new firmware and use a kernel like "Advanced Stock ICS Kernel" to root and finally reflash your stock kernel if your want its improvements, you can unlock your bootloader anytime, and the best custom room is Cyanogen, it just needs to flash an file in recovery mode.

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.
Hello,
i'm sorry if the question has already posted but i still haven't understood what to do.
I'd like to try a modded .200 rom and i'm driving an EOS rom at the moment.
What i've read is that to installa a .200 i need to go back to .55, root it, install original .200, roor&recovery and then install my preferred rom.
What i'm asking, is there a way to straight install a .200 rom? If i download a .200 original .ftf, can i flash it over my EOS rom, root it and then install my preferred rom without going trough a .55 rom?
Doesn't a .ftf install also the baseband and kernel?
Thanks

You don't have to do all that. Since you are using EOS rom , your boot loader must be unlocked so just download the .200 ROM and a .200 kernel like doom kernel or trinity kernel. Place both on your SD card. Then first flash the kernel in cwm. Then reboot and again enter cwm. Do all your wipes and flash the ROM. And yes, ftf installs the baseband also.

Hi
My phone is unlocked bootloader.
I had ultra kitkat rom on my lt18i. I wanted to install ics .13 (by jader) on my phone, so I installed lupus v16 kernel, but after all wipes, when I tried installing zip file it just went back to main menu in recovery. I tried this with both cwm and twrp, and both had same issue.
Now I just installed MIUI ics rom, and it installed with no issue.
What could be possibly wrong? I couldn't think of anything.
Thanks in advance

Flash stock ICS (any firmware), then flash LuPuS kernel and 4.1.B.1.13 firmware via recovery.
KitKat changes the partition sizes, flashing .13 does not change it back. You have to use Flashtool or EMMA to fully restore phone to stock settings and to stock partition sizes. Bootloop is probably caused by lack of space for certain system files.
But why does MIUI ICS work? And doesn't flashing kernel change partition sizes also?

MIUI might not use as much space as stock ICS does, thereby being able to boot fine.
Just kernel flashing does not affect partitions.
Correct me if I am wrong, but this is what makes sense to me.
Can someone please clarify? I'm eager to know.

Here is how it worked:
Flashed .587 ftf with flashtools
Flashed .13 using CWM with lupus kernel, strangely TWRP couldn't flash it
Thanks for help
