[KERNEL] 2.6.29.6-nAa-jb-03 [23/11/12] Custom JB kernel + CWM Recovery

---

Before unlocking your bootloader, read this thread
If you brick your device, you are the sole responsible.


Preface:

• Read through this post. Don't rush into flashing. Be sure you understand the process before you start
• This is a custom kernel developed for Android Jellybean
• Do NOT try this kernel on other Android versions - you are totally unsupported
• This kernel introduces custom mtd partitioning with larger /system partition to hold the extra JB calories. If you are moving from another custom kernel to this one, you MUST first format /system /data and /cache via the embedded CWM recovery

Features:

• Forked from nAa-ics-04 (all ICS features are already in there)
• Built with linaro-4.7.1 toolchain
• CWM-Based Recovery 5.5.0.4
• Custom mtd partitioning scheme suitable for JB
• Modular recovery flashing support (more on that to come...)
• Tracing support for JB
• pmem: bring up2date with CAF 2.6.38
• genlock/kgsl fixes
• Triple buffering support for msm framebuffer
• Much more RAM for improved multitasking experience (shakira: 186MB, robyn/mimmi: 187MB)

FAQ:
If you have any issues, please read the FAQ thread first: http://forum.xda-developers.com/show...php?p=30297163

Requirements:

• Unlocked bootloader --> http://forum.xda-developers.com/show....php?t=1254225
• MiniCM10 or any JB, source-based ROM (install this kernel first, format /system, /data and /cache, then install the JB ROM)
• Flashtool tested to be working with your phone, e.g. from here: http://www.multiupload.com/GYL7A7XQBT Original flashtool thread: http://forum.xda-developers.com/showthread.php?t=920746

Install:

• Backup
• Unlock your bootloader as described here: http://forum.xda-developers.com/show...77&postcount=3 or here: http://forum.xda-developers.com/show....php?t=1254225
• Download the kernel ftf file from here and move it to Flashtool\firmwares so that Flashtool can pick it up
• Flash the kernel via Flashtool
• Reboot and you should see the kernel boot animation
  
• (First time only) Get into recovery and format /system /cache and /data manually
  

Uninstall:

• Flash back to stock using SEUS.
  
  OR
  
• Format /system /data and /cache via CWM and THEN flash another kernel via Flashtool

Notes:

Dualtouch (for synaptics):

• If you want to enable the fake DT by dx (instead of andrej456's which is the default), you have to insert the following line in the /system/etc/hw_config.sh file:
  

  insmod /system/lib/modules/synaptics_i2c_rmi4_dt.ko

• If you want to remove the fake DT altogether, insert the following line in the /system/etc/hw_config.sh file:
  

  insmod /system/lib/modules/synaptics_i2c_rmi4_no_dt.ko

Read Before Asking Please

FAQ for MiniCM10 and nAa kernel
reading may answer to lots of your questions !
for X10mini, X8 & x10miniPRO

• i decided to create a new thread dedicated to Q&A about miniCM10

• so please, as usual, read FAQ, use search option or anything else before asking commonly answered questions
• the FAQ will be incremented when needed
• the Q&A is written as Q are asked

something else that is useful to read before asking :
Here we (nearly all? XDA members, regardless of being devs or only users [like me], me at least ) don't care about your good/bad English the important is trying to be understood and to understand the content of the threads
only ask things you can't find, or you don't understand, please if you don't understand something in any process tell us exactly where is your problem : it will optimize the answer

sometime rephrasing things can make you understand better, feel free to help us for making the most understandable sentence for anybody
BUT if you don't make the effort to read, I won't make the effort to answer (ok, you can't read everything... but read the minimum )

Chatroom for support is now available (http://minicm.ie.tc/)
clic on the red text above
register, and then enjoy

BUG
the screen stuck in rebooting dialog. It should just rebooting

ACTION
press home key (or any key maybe) to make it reboot

Perfomance :

recomended settings :
perf related :

• CPU: keep default, but enable UnderVolting (and set on boot if you don't OverClock) (settings>performance>CPU)
• RAM : to optimize RAM usage, use KSM, zram (18%, default) and allow purging of assets (settings>performance>memory managment)
• I/O : keep NOOP, this is the default and the best for flash memory

other :
in settings>developer options

• enable USB debugging,
• debug notification,
• set all animations to 0.5 (electron beam CRT animation will happen no more)
• enable "kill with back button"

________________

for whose who feel the system slow and laggy, just try the SWAP (SDcard class6+ recommended)

SWAP, there is two "kind" of swap : using a partition on the SDcard, or using a swap file
both are good, but some SDcard/phones react better with the one or the other

let us start with the partition way : it is more complicated than the file method, but as some advantages

pros: once it is set up, no need to care about it anymore, the SDcard can be mounted to PC easily without latency
cons: a little complicated to set up, and once it's done, it is as complicated to revert as to set up; to change swap size, you need to repeat the process (formating and partitioning SDcard)

needs a clean install of miniCM10:

• flash JB kernel
• in CWM, go to mount&storage :
• then, format /system, /data and /cache (so that kernel can use the new partitions size) any data on phone memory will be lost
• set up your swap:
• ==> go to /advanced/Partition SD Card
• if you don't want to use a2sd, then choose the minimal size for ext, and the size you want for SWAP
  it will FORMAT your SDcard ! any data on SDcard will be LOST
• and install the rom

swap partition should work
what doesn't work is the swap info menu

to revert : format SDcard in phone settings : it will FORMAT your SDcard ! any data on SDcard will be LOST

____________________

now, the swap file way : it is really simpler than the swap partition, works great but has some drawbacks

pros: easy to set up, easy to revert, and the size can be choosen at wish at anytime (in settings>performance>memory>Swap settings)
cons: high latency when mounting SDcard to pc, it can take forever (really quicker to use CWM mount and storage capability to use the SD on the PC, than using android way)

you must perform a clean install of miniCM10 (by formating /system, /data and /cache) any data on phone memory will be lost
install the rom zip, the gapps, and boot up your phone
set it up
once your rom is ready to use,

• go to settings>performance>memory>Swap settings
• choose "enabled"
• choose the size
• allow system to get SU permissions
• wait for the pop up "swap enabled"

enjoy, it is simple and can be disabled on wish

to see if you swap works, open terminal, and type the following :

Sorry, are you some you forgetting where you are!!

This is a Development thread so treat it like one!

Take this as your warning, any further off spam posts and you will be infracted.

Why there isnt 6.0.1.1 recovery in the kernel? Not possible or you tried and you got errors?
And second thing. Is possible to get 192 MB free in Gingerbread kernel?

whr is kernal?

This kernel has modular recovery. This means that you will be able to flash any recovery you like without the need to flash another kernel. There's no need to change everything at the same time! Existing recovery is pretty stable.

And 192MB isn't possible for GB without breaking stuff.

I can't download the kernel...
