[KERNEL] [JB] [WIP] [email protected] | Based on nAa-JB kernel with some added features! - XPERIA X8 Original Android Development

Yes guys, you read the title right.
Presenting [email protected]
Now you have a kernel with touch recovery for JB. Yeah, JB!!! It is compiled from nAa's JB kernel sources and TWRP is compiled from source, too, but not by me. Performance is almost like that of nAa's JB kernel. Maybe even better.
FEATURES
- Everything from nAa's JB kernel
- Custom MTD partitions as in nAa-JB kernels
- Built with Linaro toolchain
- CWM-based recovery 5.5.0.4 because the touch version just HAD to mess up.
- TWRP! Check this link: http://forum.xda-developers.com/showthread.php?t=1985993
- A new I/O scheduler - Deadline - that's as fast as hell especially after the tweaks from Daveee10's commits. Seriously I tried this on my phone. Super fast.
- SIO and V(R) schedulers.
- smartassH3 governor that nearly eliminates the wake up bug on JB ROMs.
- SLQB slab allocator
- H/W video decoding.
- Dual-booting JB ROMs. fehereneoh's post in the 34th covers that.
That's it for now.
REQUIREMENTS:
- Rooted XPERIA X8 with unlocked bootloader
- A lot of courage
- The ability to follow instructions (which I'm pretty sure everyone around here possesses =))
- An sdcard backup is recommended, too.
INSTRUCTIONS
- Make sure you have a copy of the stock kernel and ROM in case anything goes wrong (I'm pretty sure it won't)
- Backup using CWM
- And don't forget to format /system, /cache and /data before flashing. Otherwise the kernel won't boot.
- Download the kernel and put in the firmwares folder of Flashtool
- Follow the instructions provided by Flashtool
- Reboot and press back button several times and if you see the TOUCH RECOVERY you have succeeded in your quest

I/O Scheduler Deadline in use:**
Best AnTuTu score with [email protected] on smartassv2 and Deadline I/O scheduler. Stock 2GB sdcard was used. I swear to God no tweaks were used:**
Since I forgot to take a screenshot of the "Detailed scores", I'm uploading the score record XML file as well (mostly for skeptics). It hasn't been tampered with. What you believe is up to you, though:

BUGS
- Rebooting to recovery from ROM works but if you reboot to system from CWM it keeps booting to CWM. Wipe cache to solve this.
- SDCARD gets formatted sometimes. This bug has been confirmed removed by testers. But you should always be on the safer side and have a backup.
DOWNLOADS AND SOURCES
Downloads: http://d-h.st/qGM V8: http://forum.xda-developers.com/showpost.php?p=38189560&postcount=511 Thank CnCprior to downloading, as it wouldn't have been possible without his efforts. Much appreciated bruv.
Kernel source: https://github.com/souljaboy11792/oxydo-kernel-jb
Use the master branch and as EET has advised, use this instead of zipballs or tarballs:
Code:
git clone https://github.com/souljaboy11792/oxydo-kernel-jb.git
Ramdisk is present in the source (after extraction of course) as kernel.sin-ramdisk. Copy it some place else if you want to pack it.
Tha above basically means I am fully compliant with GPL. Thanks go to nAa, pilu1978, CtrlAltDelIrl, EET and all the others who warned me.

TO BOOT INTO TWRP, TOUCH THE SCREEN WHILE THE LOGO IS BEING DISPLAYED.
TO ENTER CWM RECOVERY, KEEP PRESSING BACK BUTTON WHILE LOGO IS BEING DISPLAYED.
ENJOY!
NEITHER ME NOR ANYONE RELATED TO THIS KERNEL CAN BE HELD RESPONSIBLE IF YOU BRICK YOUR PHONE BY FLASHING THIS. PLEASE HAVE A BACKUP OF YOUR SDCARD BEFORE FLASHING AS THIS MAY FORMAT IT. THIS BUG HAS BEEN REMOVED AS CONFIRMED BY TESTERS, BUT HAVE A BACKUP BEFOREHAND TO BE SAFE.
NOTE: I still consider it a WIP. Therefore bugs may exist. However they shouldn't cause much damage. And bug reports are always welcome. You can use this kernel. If you like it, just press the "Thanks" button. Don't spam, please.
**If you're wondering how I got my phone's UI to look that nice (it is nice, isn't it?), just set LCD density to 120. Text is a little small but I can read it without glasses, so it's all good.

THIS WORKS WITH ALL JB ROMs THAT ARE BASED ON THE MINICM10 ROMs (Nightly or stable version doesn't really matter here)
MAKE SURE YOU HAVE A JB ROM BACKUP THAT YOU CAN RESTORE. OTHERWISE YOU'LL FACE THE assert getprop ..... ERROR.
AFTER RESTORATION, YOU CAN INSTALL ANY JB ROM.
OR
YOU CAN EDIT THE UPDATER-SCRIPT IN THE ROM.ZIP. REMOVE THE assert getprop LINES, AND THEN PROCEED WITH INSTALLATION. THIS IS NOT ALWAYS SAFE AND CAN CORRUPT YOUR ROM.ZIP FILE.

CHANGELOG
-30-10-12
* Initial release
* CWM touch recovery from Alfs' kernel
-8-12-12
*TWRP
*Both versions of CWM touch recovery integrated into one ramdisk
*FPS-uncap (maybe?)
-15-12-12
*Removed CWM touch
*Included CWM 5.5.0.4
-18-12-12
*Forget 5.5.0.4. CWM touch 5.0.2.8 is back in two different kernels.
*MD5 mismatch is still un-fixed. Official error (I guess).
-1-1-13
*New Year's Release (not really, built it quite some time ago).
*Added Deadline I/O scheduler (not quite sure why nAa-jb doesn't have this; it is blazing fast).
*Better TWRP UI (thanks to CnC for providing the awesome buttons and the sliders).
-7-1-13
*Added SIO and V(R) schedulers.
*Tweaked Deadline a bit from Daveee10's commits. Super cool now.
*Added smartassH3 governor.
-12-1-13
*Used SLQB slab allocator instead of the default SLAB.
*Applied the PMEM commits from nAa-jb-03. H/W video decoding works perfectly now.
*Edited the bootrec to make sure two recoveries aren't booted at once. Sdcard bug gone for now.
*CWM backups work. You just have to mount /system and /data. Don't pull out the battery when it's backing up. It's actually in progress, although the progress bar is so thin, you won't be able to determine whether it's actually working or not.
*New TWRP theme. Credits: thecoby for the original theme and an0nym0us_ for resizing it to MDPI.
*Fixed the I/O schedulers bug. Credits: Daveee10.
DEVELOPMENT PLANS FOR NEXT RELEASE(S)
- New bootanimation (similar to Nexus ones)
- Powerboost and some other newer ondemand governor features. Also thanks to Daveee10.

Thanks for this Kernel, Good work.

---

The thanks button is just below the profile pic. Thank me later if you ran out of thanks for today.

---

Added your name to credits. By project list, are you referring to nBoot? Top-notch work that, though we couldn't get it to work.

---

Just a suggestion:
Why don't you make this with FPS cap OFF too, like in the ICS kernel... Wouldn't there be more performance enhancements?

---

Will do. I'm trying to port TWRP to ICS now. Will come back to this after that is done.

Click to expand...
Click to collapse
Is this recovery working goood?
Is it in 100% working and I won't brick my phone?
Thanks

---

This kernel is working perfectly. No bugs at all. Next version will have TWRP hopefully. I'll start working on 15th December after my exams are over. Please be patient.

---

Post #2 updated. Please read before flashing.
Next version will have TWRP.
And I will also experiment with FPS-uncap.

---

this kernel work in the new rom 4.1.2 ??

---

It does.

---

I'm trying to install the latest minicm10 with this kernel and i'm getting Installer Status 7 all the time, with naa-jb kernel i don't have that problem, any suggestions?

---

Read post #2.

---

POST #2 updated. PLEASE READ POST #2 ROM-COOKERS.

---

Kernel dev is back nice one !

---

You wrote in the third post how this works with all JB rom.... That's false... Not working fully with JBMiniProject... SD-Card not working and USB connection to PC too....
So the correct description is:
This works with all JB roms what based on nAa's JB

---

And thanks again Daveee10.

---

This new kernel and new opportunities so I'll have to go ahead and do it to my roms work with this kernel because I see that it is really worth
