[Acro S][Kernel] Stock Kernel + CWM + Root (updated latest 6.1.A.2.55)

[Disclaimer] Do it at your own risk. I am not responsible for anything happened to your phone.
Hi all, I've just upgraded my phone to Acro S recently. It is running ICS 4.0.4 build 6.1.A.1.58. It has been updated to 6.1.A.2.55
So here is a modified Stock Kernel with CWM which I created based on Arakmar's Stock ICS kernel (Build 11) for XS
Credits:
1. Arakmar - for the ramdisk and CWM
2. DoomLord and FXP team - for too many things to mention

Instructions:
1. Unzip the files to the fastboot folder, there are 2 files:
kernel.sin -- Stock ICS Kernel
kernel-cwm.elf -- Stock ICS Kernel with init.d support and CWM 5.5.0.4
2. Get into fastboot mode, type:
- To flash the CWM kernel
Code:
fastboot flash boot kernel-cwm.elf
- To flash back the Stock kernel
Code:
fastboot flash boot kernel.sin
To get into CWM - Reboot your phone, tap the screen (not buttons) a few times when the blue led and button lights appear
To root your phone, follow instructions here: http://forum.xda-developers.com/showpost.php?p=30320507&postcount=11

Thank you.
But i have a question: what is ram disk use for?
I used xperia s mod kernel to flash supersu.apk, then flash back stock arco s kernel, and add CMW. But some .zip file can not use.

Does this give us root or do i need to root the phone first and then flash this kernel ?
Also, do we need to unlock bootloader for this ?

Can anyone please comment on performance? Thanks in advance!!

Hi do i need to flash these 2 files or just one i want cwm.and does it include root or not?

ramdisk is part of kernel. it runs initial scripts that control how the phone starts.

You need to unlock bootloader first. This kernel won't give you root. But you can boot into cwm to flash any package that root your phone or you can flash a complete rom, if available.

You need to flash only the one with cwm. It won't root your phone.

Thanks for your reply,is it ok to flash cwm without root first?and unlock bootloader is the same xperia s right?

I think you're right. The moded kernel is kernel-cwm.elf.

Root Package
Here is the Root package after you flash the kernel with cwm
To root your phone:
1. copy the RootPhone.zip file to sdcard (internal storage)
2. reboot into cwm
3. install the package
4. reboot

Sorry.
Ｔhanks　alot.

It works on Acro HD with Acro S's ICS ROM flashed exlude baseband.
UPD: I did not like the ICS. There are only 320 mb of free RAM. I have 460 mb of free RAM on 2.3.7. So, I installed back the 2.3.7

if you could add 2way call recording patch to this kernel would be great

This worked for me, unlocked bootloader, flashed kernel-cwm and then flashed rootphone in CWM. Thanks.
Just a suggestion,
You might wanna add "+ Root" to your title seeing as this is another way to root the device.

With CWM, can we then flash custom ROMs for Xperia S or a Kernel with permanent root (e.g. DoomKernel)?
I'd like to get rid of all the Facebook-crap in the stock ROM but if it will be there again after the next update from Sony it's no use.

Once you unlock bootloader, you can flash any custom kernel.
If the kernel comes with CWM, you can flash any rom/zip with root
But I think current S custom kernels/roms are based on older version: 6.1.A.0.452

Bootloader unlock will probably void warranty.
But how about rooting? No righht?

Where to find the tools for unlocking bootloader.
Would appreciate a link if anybody now...

in step 3 you must uncheck some thing in flashtool but i forgot them ...
instead you can use unlocking your bootloader and then flash stock pre-rooted kernel and install SU on your rom...
(its very easier than your way)

Maybe you can try the one click root... It's there in general section...

If you're going to use Stock ROM
if you flashed back .587 ftf, you probably left all .sin checked. You should have unchecked kernel.sin, No final verification unchecked.
Reflash custom kernel. If still no root, flash flashable zip in SuperSU thread
If you're going to use a custom ROM
Just flash respective kernel, wipe data,cache,dalvik,system in CWM and install rom. No need to root .587, flashing .587 is for increasing partition only(in case).

If your BL is unlocked you should download Rom and kernel that you want
rom must be .zip and you should place it in sd card
kernel must be .img or .elf
and kernel Wi-Fi modules must be .zip and you should place it on SD too
then you download QuickIMG tool and place the kernel in images folder of it
then turn off phone and hold menu key and plug usb cable
LED would be blue
then you open QuickIMG and choose your kernel and flash it
then turn on phone
when the led is blue you should press Vol down key
then you enter CWM
do:
-wipe date
-wipe cache
-mount and storage > format/system
-advanced> wipe dalvick cache
then install zip and choose Rom
then install zip and choose Wi-fi modules
reboot...

CM10 you say then you need a custom JB kernel, like Fusion,Lupus or nAa kernel, or whatever kernel you want.
You don't need X-Parts. There are many tutorials out there. But I'll just help you.
Download kernel and paste to pc, in any folder.
1) Flash .587 ftf
2) Flash custom kernel (with phone off, hold menu button, connect to pc. Go to Flashtool, then click the thunderlike button, select fastboot mode, select kernel to flash, point to kernel file)
3) Boot, then repetitively press back button to boot to CWM. If lupus kernel, it is volume down.
4) wipe data,cache,dalvik cache,system
5) Install ROM

[Q] Please Help Me CWM

Hello, I am new in this forum. I can speak English so so I am not good at.
I have GT-I8160. First upgrade JB official. It's very slow. And I downgrade GB. First I install Russian Official GB Rom. Because this rom have partition files. After I install XXLK6 with Odin. I now use I8160XXLK6 but my ClockWorkMod is very easy. It havent flash option. So I cant flash rom. Please help me, for I8160XXLK6 CWM how can install ? İts very important.

Install custom kernel with terminal emulator. Than you will have cwm. For that you must have root. I suggest you to flash, with Odin, pre-rooted xll2 firm. Kyrillos make whole thread about that. Search here in general section. Good luck.

[Q] eXistenZ v2 Error 7

Hi guys i have a problem when I instaling the eXistenZ v2 on LT26. I rooted my phone i have recovery and when i install a rom have error nr 7 in revovery, any ideas?

Flash the kernel file from the rom itself
Try flashing the kernel from the rom itself bro this works most of the time Extract it first from the zip file of the ROM you want to install then install the kernel usually it is the boot.img file Flash it via fastboot mode using flashtool then voila you have the kernel of the ROM you want to use and most of the time the recovery comes with it too :good:

Are You on stock firmware? Existenz requires You to be on stock 6.2.b.1.96 firmware. Also, You have to flash v1 and then flash v2, not the v2 directly.

Do check, this ROM is stock based, so it doesn't have a separate kernel.

I flashed witth stock 6.2.b.1.96, and try to flash V1 witch recovery v6.0.3.0 but still error ''Error in /sdcard/xperia_s_existenz_v1.zip (status 7)'' Maybe try with other kernel?

Huh, weird. Just to verify, could You try downloading the v1 again? Or else, do You have a unlocked bootloader? If yes, then You can flash the DoomKernel.

Yes, i downloaded rom again, and i have lock bootloader witch no posibly to unlock 'allowed-no'' something like this, but this rom can be flash without unlocked bootloader.

Well, since You have a locked bootloader, You can't flash other kernels. Try this recovery, If even this one doesn't work, then try going back to full stock(no root, no recovery) and root using DoomLord's method and try above recovery again as it had worked for Me earlier.

This is waaaay late but, may help someone.
As I understand it, this is an issue with the kernel/recovery you have. You need to flash a boot.img with a combined kernel/recovery that is compatible with the rom you wish to flash. You use fastboot for that:
Code:
fastboot flash boot boot.img
fastboot reboot
So, for official CM11, grab boot.img from the rom zip file and you should get (a rather old but fine for CM11) CWM recovery.
For many other Acro S (hikari) roms you find - e.g. @deedwar's BeanStalk - you will get TWRP recovery if you flash the included boot.img file.
Once you've got the kernel/recovery flashed, then you flash the full rom after the reboot.
