I'll give it a test tomorrow :-)
[Sony Xperia S, Acro S, Ion] tot_anusak:
You can rename the backup using ROM Manager app. This approach doesn't ruin the checksum.

From my experience, renaming it from apps like file manager causes restore not work.
[Sony Xperia S, Acro S, Ion] Phantasm4489:
No it doesn't affect the md5 just make sure you don't rename it to anything that contains spaces.
[Sony Xperia S, Acro S, Ion] amfirbek92:
It's ok mate..flashed back ics8 no more lags..installation is faster and no crashes;)

Hey arakmar,

To fix "reboot recovery" try this:

https://github.com/CyanogenMod/andr...10c1dbde6e7697ac6/prebuilt/postrecoveryboot.s

Put postrecoveryboot.sh at /sbin/postrecoveryboot.sh with correct permissions
[Sony Xperia S, Acro S, Ion] Arakmar:
Thanks for the link !

I already implemented that in a similar way ;)

https://github.com/Arakmar/xps-ics-ramdisk/blob/55ebe0364d4d240ebffd0322b0657cec557677cf/sbin/reboot

I'll release a new version when all errors with GCC 4.6 are fixed.
[Sony Xperia S, Acro S, Ion] Ben36:
Works fine renaming them! Just tried it out! :-)
[Sony Xperia S, Acro S, Ion] tot_anusak:
Thank you for information. However, I never rename the backup with name containing spaces. So it is possible that the problem I found may be caused by something else. (Sorry, I forgot to tell you that I have this experience with my old device)
[Sony Xperia S, Acro S, Ion] SFU11:
hi, can I flash this kernel with locked bootloader via CWM? since CWM can be implemented even with locked bootloader.
[Sony Xperia S, Acro S, Ion] Vipitus:
No, you can't change kernels with locked bootloader ;)

[Sony Xperia S, Acro S, Ion] tot_anusak:
Today I tried unpacking the kernel. I found this line in autoroot.sh

rm /data/app/Superuser.apk

The reason why this doesn't work is that the apk under /data/app isn't named "Superuser.apk" but something else which is quite long. For example "com.xxx.yyy.zzz.Superuser.apk" (sorry, I forgot to save its name). I guess that this problem occurs only when users root their device using the old-versioned SuperSu and then update it later via Play Store. To workaround this problem, we can manually delete that apk from /data/app.

Sorry if you have already known the root cause and fixed it in ics10. ;)

In addition, because I also prefer SuperSu, I modified ics9.elf by replacing the SuperUser files with SuperSU v0.93. All credit goes to Arakmar for the original advance stock kernel, championswimmer for the kernel kitchen (I've pressed "thanks" in the thread) and Chainfire for SuperSu.

Because the only thing I did is just replace the files. The problem above isn't fixed. You still have to manually delete it. :P

Hope this is useful for those who also prefer SuperSu like me.

Build 10 is out !

So, "reboot recovery" works everywhere excepted with this entry in CWM : Advanced -> Reboot recovery

I'll fix that in the next build which will contain a custom CWM.

Fixed in build 10, thanks for reporting that ;)

That won't help at all AND it should be enabled already.
[Sony Xperia S, Acro S, Ion] ttiimm:
whats GCC 4.6? is it like -o3 or something? im guessing its to do with the way you compile the kernel
[Sony Xperia S, Acro S, Ion] K900:
I have zero idea how you know the flags for it, but GCC is the thing that compiles the kernel.
[Sony Xperia S, Acro S, Ion] Poesini:
Some questions... If you can answer them...

As said, how did you compile it with GCC 4.6.6 (And not with 4.7.1)

And also, whats the gain (I would say speed it pretty hard to find) in size (if there is)?

Thanks :) :good:
[Sony Xperia S, Acro S, Ion] Kyrius:
So how do i enter recovery? I've tried everything but it just goes on booting into android.

[Sony Xperia S, Acro S, Ion] tot_anusak:
Oops.. Mine also has the same problem. Haven't tried this with ics9 yet.

Update: I don't see this problem with ics9 as well. However, I really love "Boot into recovery". Looking forward to ics11. :p
[Sony Xperia S, Acro S, Ion] Arakmar:
Thanks all for reporting that.

It seems that there are some incompatibilities with GCC 4.6. I even tried with linaro one, same issue too ...

So I go back to 4.4 until I find a solution.

So ics11 is out with the kernel rebuilt with GCC 4.4.

[Sony Xperia S, Acro S, Ion] ChefChaudart:
Are SuperSU & Superuser both useful ?
[Sony Xperia S, Acro S, Ion] Kyrius:
I can confirm screen flickering when camera on as well. A lot less when filming, but taking photos is quite troublesome. Everything else seems to work quite well. Battery life is outstanding after setting max freq. to 1242 and it is still smooth.

EDIT: 11 is ok! no flickering
[Sony Xperia S, Acro S, Ion] matlear:
Lots of flicker on the camera for me too ... No camera flicker though whilst using instagram or cameraFX ....

Could somebody explain the reboot into recovery for mer ? how does this work ?

When the phone starts, at a moment, all light will light on. At this moment, press several times Vol. up.

Reboot in to recovery is when you use the command or widget to reboot the phone directly into recovery, without pressing the volume rocker when the phone boots!

I've had roughly the same battery life with both xsx and build 11.

I think I had better battery life with build 8 to be honest.

[Sony Xperia S, Acro S, Ion] ttiimm:
restoring backups are also a bit of a hit and miss for me. sometimes they work other times they fail.

on the other hand, battery life is the best for me on this kernel. 23hrs and 42minutes later, im still on 24%:D:D:D

if i underclock to 1.2 ghz battery life is even better, and my phone still runs without lags or glitches
[Sony Xperia S, Acro S, Ion] tot_anusak:
Yes, md5 works fine since ics5. But please be aware that nandroid backup created by ics4 can't be restored using ics5 or newer.

"ok here's a zip

http://icxperia.com/championswimmer/nozomi-xperia-S/kernel-flasher.zip

place the desired kernel you want to flash in /sdcard/kernel.elf

in recovery go to mounts and storage, mount sdcard, and then flash this zip ￼

(this will flash the kernel.elf file in sdcard to boot partition.. use it carefully... it can soft-brick your phone if you use an improper kernel)

DO NOT FLASH THIS ZIP IF THERE IS NO FILE CALLED kernel.elf PRESENT IN SDCARD"

Does anyone have this kernel-flasher from page 16? The link is dead.

Also, would it be possible to set this up for a boot.img file? Or is kernel.elf and boot.img interchangeable? Meaning, cam I just rename boot.img to kernel.elf?

[Sony Xperia S, Acro S, Ion] elvirag:
That's exactly what this is!!!

Go to CMW, choose install zip from sdcard and flash this file.

Don't forget to thank me... how n00b of you. Go read some more on stuff, instead of saying stupid things.

There is no such thing as kernel flasher, there is name_of_kernel.zip you can flash in recovery...:banghead:

You're a noob here. There IS a kernel flasher that can load kernels from sdcard instead of embedding in the zip.

Oh... so it's a new thing? Sorry.

So excuse me, what does it matter? What is the difference between .zip or flashing .elf?

And to complete K900 post, just for your information, I provide an update.zip for each versions in the first page.

I gave the link because I thought that was what's not working... sorry again...:(
[Sony Xperia S, Acro S, Ion] K900:
The .zip is just a wrapper for the .elf that lets you flash it without a PC. The kernel flasher can use any .elf.
[Sony Xperia S, Acro S, Ion] veryproudmonkey:
Aaaanyway,

Was looking for the wrapper to see if I can flash the fxp 130 cm9 kernel without having to use fastboot. Though it may not be possible if I cannot just rename boot.img to kernel.elf... But wanted to give'r the good old college try.

Be careful for CWM, the default behavior for backups has changed.
