[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

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

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?

[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.

[Q] Rooting z1 compact stock lollipop

We all have gotten a sneak peek of Sony's lollipop update onto our beloved z1 compact. Through the many ways available I for instance used an ftf file. But they do not come pre-rooted like the zip file alternatives.
The only way to root ftf I am told is to flash a kernel pre-installed with a recovery then flash SuperSU zip. I have flashed like 3 different boot.imgs only to find no TWRP/Philz/cmw recovery.
Can anyone give me a WORKING kernel that will boot into a recovery? Would really appreciate this.
Found my solution
Edit: I just found a cm11 snapshot boot.img kernel, flashed it. Booted to recovery and flashed a pre-rooted rom zip. Easy as pie.
Thanks all.

Just flash KK firmware 108, root it, install recovery latest version, and afterwards flash any customised prerooted ROM of your choice.

This is too much work. Work that I have to do. It's the only way to root this ftf. damn it

It's up to you.

I've done it.
I made a pre-rooted ftf using PRF creator and compiling the SUPERSU v2.37 and Z1C locked dual recovery 2.8.12 from Nuts site.
You can use Xperifirm to download the the firmware, then use Flashtool to decrypt the fileset and create the FTF, then you're good to go.

I'm from the UK but I used the "Customized US" version. It works all the same, I've put together a UK one now but I'll need to wipe data before I can use it.
I'd share if I didn't have awful internet. The file is massive, unfortunately.
You'll find multiple threads on how to do different parts.
You need to create your pre-rooted firmware, then you'll need to download KK with Xperifirm (probably .108) and flash it with Flashtool.
Root KK using Easy Root Tool and install XZDualRecovery using the desktop client.
Once you're rooted with SuperSU/SuperUser and Recovery you can install the pre-rooted firmware (PRF) as a flashable zip within Recovery itself.
There's also work arounds for Xposed which you can find too, I've used them and it's all working as it should for now.
I also have a locked bootloader, so don't worry about unlocking it. I'll have a look around for the threads I used and post any I find.

I'll leave you to find your own SuperSU or SuperUser zip, same with XZDualRecovery as they're frequently updated so you're better off finding the latest versions.

OK, there seems to be some loss in translation somewhere. Hope this will clear up some stuff:
1. Flash KitKat (kernel, system, everything).
2. Root it.
3. Install recovery (here)
4. Since you don't want to make your own pre-rooted firmware, here. Click on 'Google Drive' for the zip, and FTF. You need both.
5. Put the zip in your SD card/internal.
6. Boot into recovery and clear all data (dalvik, system, data, everything).
7. Flash the zip. DO NOT REBOOT.
8. Shutdown and use Flashtool to flash the .ftf you downloaded. Check System and Baseband on the 'exclude' column.
9. Have fun!

@dazzerfong OK,first of all thanks for your answer. What I'm asking is how did you do the first step with locked bootloader.
Flashtool->Flashmode->KitKat 157 FTF->Then root it blah blah?
Are these steps correct or not? Im about to try today cos I really miss root on my phone.
If you are already on Lollipop and your bootloader is locked you can get root this way.
1.Download the correct KitKat (.157) ROM for your country/operator using Xperifim.
Convert it to FTF using Flashtool. (there are tutorials,search)
2.Flash the FTF you created using Flashtool's Flashmode. Include everything.
3.Root your KitKat (.157) using the forum's tutorials and also install [NUT]'s recovery.
4.Boot into recovery and flash your pre rooted ROM in flashable zip format.
(There are also tutorials on how to create this with Xperifim and PRF programs).
5.Enjoy rooted Lollipop with locked bootloader.

Yep! All done with locked bootloader (or, if you want, unlocked, but you're wasting your time if you're unlocked). So, first you flash the FTF of a KitKat ROM.
Rooting, use Towelroot or something. No idea why, but Towelroot refuses to play with my TWRP (recovery), so I used the old method.

@dazzerfong
One last question cos I just did all the steps but I couldnt reboot into Lollipop after flashing my pre rooted rom zip file.
6. Boot into recovery and clear all data (dalvik, system, data, everything).
7. Flash the zip. DO NOT REBOOT.
8. Shutdown and use Flashtool to flash the .ftf you downloaded.
Check System and Baseband on the 'exclude' column.

On step 8 which FTF you mean exactly? I assume you mean the FTF from which you created
your pre rooted zip initially? In my case the Customized GR version?
N.

You should have downloaded 2 things so far: the zip, and the FTF. That FTF is Lollipop stock: doesn't matter where it's from. Flash that in Flashtool, but remember to check 'System' and 'Baseband' in the 'Exclude' column.

Downgrade to .108 (with flashtool) in order to directly root the phone, whereas with .157, you'll have to flash an older kernel with flashtool in order to get root.
Once rooted, just get yourself a flashable prerooted firmware (zip file) and flash it from the recovery (after a wipe factory reset; wipe data; wipe cache; wipe Davilk Cache and Wipe System).

[Q] Xperia Z1c has no recovery

Hi
My problem is that it seems my Xperia Z1 Compact has no recovery. I rooted it by downgrading to .108 kernel, rooting and flashing .157 kernel.
I don't know if the no recovery problem was right after this but now I wanted to upgrade to android 5 and discovered I have no recovery. I tried:
manually to recovery (the LED won't even light up)
quickboot app
via adb
I also then unlocked bootloader and flashed kernel .sin again to see if this helps but no.
Please help

fastboot help you to put a kernel which is entered in the factory recovery partition. but you'll have to flash the (SLIM,RRREMIX) boot.img up and recovery.img the correct partition.

If I am on stock recovery and unlocked bootloader, is it possible to root my phone without twrp by flashing magisk zip in stock recovery?

No. Stock recovery will only flash images & zips from OnePlus.

Stock recovery only works with officially signed files from OnePlus.
If you already went through the trouble of unlocking the bootloader then flashing a custom recovery is very easy and straightforward. Otherwise you might as well relock the bootloader.

Theoretically it is possible with MAGISK (even with locked bootloader) but it didn't work for me...
Steps:
1. Extract the boot.img from stock rom zip
2. Patch with Magisk Manager
3. Rename the patched one to boot.img and replace in stock Rom zip
4. Flash the zip in stock revovery
Unluckily I finish with a "Installation failed" error
Did anybody managed this with 5.02 rom and locked bootloader. I got told that for older stock rom it was possible

No, no, no...
What you do is that you let the Magisk Manager patch the stock boot image (as in 1 & 2 above). Then you use fastboot to flash the patched image to your device. No custom recovery needed...
Code:
fastboot flash boot patched_boot.img
Your bootloader has to be unlocked though.

With fastboot I also tried without success. As you told, it is required that the bootloader is unlocked.
