Advance Stock Kernel 17 comes with CWM.

How Can I install this over CMW?
[Sony Xperia S, Acro S, Ion] Redstarr1:
You should take a look at the "Download - FOTAKernel Image" header. There's no need to install that stock kernel, you can also just push the recovery. The way described on the website requires you use Terminal Emulator but there's an easier way. (I also don't really understand which is the right version because there is 2.4.3.0 for nozomi and 2.4.3.0 for LT26i and afaik that's the same device).

Just install GooManager on your phone, select "Flash ROMs" and there should be a message asking if you have a custom recovery. Select to install one and the latest version of TWRP will be installed.

I'm using Stock+ kernel, that already had TWRP 2.4.1 recovery, after doing this with GooManager I have TWRP 2.4.3.0. If you're using any of the other .55 kernels it should be work as well.

No idea.

That's basically the same question eScapeeXc asked so the answer is the same ;).

Re: [RECOVERY] TWRP 2.4.3.0 touch recovery [2013-03-01]

Is it works on locked bootloader?
[Sony Xperia S, Acro S, Ion] Apology11:
Will:

dd if=/dev/zero of=/dev/block/mmcblk0p11

remove the recovery?

Is there a way to choose between the recovery from the kernel and this one on fota while booting?

How many space has the fota partition on our device?

Does this mean that flashing TWRP on Xperia S, this way, will prevent it from being overwritten every time a new kernel is flashed?
[Sony Xperia S, Acro S, Ion] tosa.th:
Keep in mind, if kernel you are using doesn't implement elf extract then it will not read FOTA partition so it still use recovery that came with kernel.

And almost all kernel came with CWM.

But maybe raymanfx has not implemented this

Btw that recovery is a crap.. Try advanced stock kernel
[Sony Xperia S, Acro S, Ion] raydekok:
just flash this thru the current recovery?

and install rom again?

I don't use FXP, so I don't know is it support elf extract.

Check with FXP team about their kernel if it does support then you are good to go.

And if you are able to boot the ROM you can use Twrp manager ...

Download doomkernel from here

Then extract the kernel elf and flash it by flashtool or through adb.I always use flashtool coz its easy to use.Then u can enter to cwm recovery.

Then if u want to use twrp then go here and download the file.Then enter to recovery and install the zip file.

Well, when I flash the recovery my phone was on 4% and after that I've rebooted it and won't turn on, one question is it Hard-bricked or can it be fixed? cause flashing stock FW like what you said fixes everything, it fixes all modified partition..(looking at the increasing data partition tutorial)
[Sony Xperia S, Acro S, Ion] nageswarswain:
if your phone is charging the put it on charger so that it can charge sufficiently for the flash....

i hope flashing stock official fW will solve your problem.Ya the data partition will revert back to 2gb after flashing the Stock FW.

the "package" probably is TWRP, in b27 is the 26 Oct one, while you are using a newer one. You may try to remove recovery.img from zip file (but probably some script will be broken), or may try to replace recovery.img with your twrp
[Sony Xperia S, Acro S, Ion] SdtBarbarossa:
ok thank you! this error happens because of my builddate of twrp is newer then your rom (why your rom even checks that?)

i will reset the builddate to 2014 :)

I tried to install TWRP Manager via App Store and download the latest build but after it says it is downloading it screen changes to a log of random symbols/letters/numbers etc. Has anyone come across this issue? (Also phone is rooted and bootloader is unlocked. It is not the first time installing recovery but it is the first time this has happened to me). Xperia S LT26i Nozomi
[Sony Xperia S, Acro S, Ion] mirhl:
So download the file from the browser and use the manual flash method
[Sony Xperia S, Acro S, Ion] Torroan:
I flashed TWRP via Flashify from the .img file but the phone soft bricked (Stuck in recovery mode) and i had to flash it again back to stock ROM.
[Sony Xperia S, Acro S, Ion] nageswarswain:
If you flashed the twrp by flashify then it will just replace the kernel file of the rom.so its only booting to recovery as it has no kernel file.so if you want to again boot to that rom you have to flash the kernel of that rom via recovery or by fastboot.you don't need to flash the whole stock ftf to recover from that soft brick.so it is recommend to flash the twrp recovery to fota partition which doesn't replace the kernel file.

So do it as mirhl said by manual method...
[Sony Xperia S, Acro S, Ion] Torroan:
Figured as much. The point is i do not know how to use adb so i would really appreciate a pointer :P Website says "dd Install Method (Requires Root):

Download the latest image file (.img) from the download link above. Place it in the root of your /sdcard folder and rename it to twrp.img. Run the following commands via adb shell or a terminal emulator app:

su

dd if=/sdcard/twrp.img of=/dev/block/mmcblk0p11"

So i just put it in my sd card go to the adb folder in my computer open cmd with shift+rightclick and type

adb shell

su

dd if=/sdcard/twrp.img of=/dev/block/mmcblk0p11

?
[Sony Xperia S, Acro S, Ion] nageswarswain:
Read here
[Sony Xperia S, Acro S, Ion] Torroan:
Hmmm looks like it doesn't work although terminal said it copied the files and everything was okay it didn't show me the usual pink light. It could be that my kernel doesn't support it but if i recall i've used the same FTF Stock(XperiaS_LT26i_6.2.B.1.96_1257-6919) over and over every time something happened but back then it used to work. Any ideas how to change the kernel to one that supports it but is similar to stock?
[Sony Xperia S, Acro S, Ion] mirhl:
Of course no way it will work with stock kernel.

Use a custom stock one, like doomkernel.
[Sony Xperia S, Acro S, Ion] Torroan:
Could you please give me a link to download that kernel? And as of installing it flashtool will suffice i suppose?

Anyhow last time i rooted my phone i did it with DooMLoRD Easy Rooting Toolkit but this time it failed so i used another method thought i do not know why it failed

to work with DooMLoRD this time. But the thing is last time all i did was root the phone and unlock the bootloader then i installed recovery i never changed the kernel

unless the Rootkit did it by itself.

Cannot run twrp properly..

Hello all! This is my 2. time messing around CFW( first being ~3y ago so nearly everything forgotten) and I can't install TWRP recovery.

1) Twrp manager just loads .img file as text( as somebody mentioned earlier)

2) dd if method says that I dont have some permission to write data

3) fastboot flash recovery recovery.img successful but doesn't boot recovery.. regarding this, I have just understood that I need custom kernel to be able to boot custom recovery so I flashed dromlord kernel which seems to boot into recovery but CWM and pressing camera key into TWRP but version 2.55 although I flashed 3.00 into recovery over fastboot..

Rom is 1.96 with unlocked bootloader and root!

The only way to load TRRP is to flash it it to boot thus making it impossible to boot into any rom ( Can I use TWRP run this way to repartition and flash 6.0 b07( which is my primary intention) without ever properly installing it..? )

ps: twrp manager says that 2.8.7.0 is installed and so does Flashify which crashes when I try to flash twrp to recovery.. (happens instantly when "from file" is pressed)

Also, where can I read and find out about partitions on xperia s( whole fota thing, been reading about partiotns under android in general.) - what partitions exist..?

All in all I would like clarification around this: "The Xperia devices have a recovery-in-boot arrangement. This means that the recovery is booted using the regular kernel / boot image in the device. Team Win has worked with the FreeXperia device maintainers to come up with a way to extract the ramdisk from the FOTAKernel partition and use the ramdisk from that partition instead of the recovery that is included in the boot image of your device. This means that if you install current CM nightlies and flash TWRP to the FOTAKernel partition, you will be able to use TWRP instead of the CWM or CM recovery that normally comes in a CM boot image. Other boot images including stock kernels can be repacked to include this extraction utility to allow you to use TWRP from the FOTAKernel partition. This setup allows you to choose what recovery you want to have installed and allows you to update your recovery more easily. Unfortunately this setup requires that the boot image that you have installed include the ramdisk extraction utility. The source for this utility is here"

Thank you.

This specific recovery needs a custom kernel because the recovery is stored in the FOTA partition. For locked bootloaders there is a (buggy) CWM recovery: http://xdaforums.com/showthread.php?t=1756346 (for Xperia S the version is by PuriketsuAngel).

If you'd unlock your bootloader, most custom kernels support this recovery, although I can only really verify this for the Stock+ series. I think advanced stock ICS kernel doesn't support it. You'll just have to see yourself, flashing kernels isn't that much work.
