Hey guys, I just converted a kernel for SHW-M440S

SiyahKernel S3-v1.7beta1.. It was released yesterday: October 6, 2012

Changelog:
Dual-booting (supports only JB ROMs: Samsung JB and CM10)
fixed a UMP related bug in v1.6.8 that was causing lags for CM10 users
removed CPU locking when GPU freq >=440MHz
alternate touch recovery for secondrom related operations
Some 2ndROM features are missing. Implemented features are: Clone 1stROM to 2ndROM, Clone 2ndROM to 1stROM, Swap ROMs, Delete 2ndROM.

TODO:
implement missing 2ndROM features
make a CWM-flashable 2ndROM-utils app
implement more accurate space requirement checks

Some recovery details:
CWM-based Recovery v6.0.1.4
default backup format is set to tar (you can set it to dedupe)
In kernel recovery options: delete stweaks defaults or remove init.d scripts
In dual booting menu: swapping, cloning and other 2ndROM related options
swipe gestures support (up/down to choose menu items and right/left to select/back)
doubletap to select (needs a little more tuning though)
uses Samsung JB stock kernel recovery as the base

Some details about dual-booting:
2ndROM system partition will be kept in /sdcard/.secondrom/system.img. You will need 1.5GB space for the 2ndROM system partition in your internal sdcard.
both data partitions in 1stROM and 2ndROM will use the same space. Make sure you have enough space to hold both system and data when you clone 1stROM to 2ndROM.
hidden partition is used as 2ndROM cache partition.
Flashing a new ROM may flash another kernel and you will not be able to boot into 2ndROM anymore. But you will not lose it unless you delete “.secondrom” folder in your internal sdcard. So, flashing back SiyahKernel will let you boot into 2ndROM again.
See this post for more details. It is for S2 but still useful to understand what dualbooting is about.

I just tested this earlier and it works fine.. I will continue to convert more kernels. This is my first convert.

Rgui miui ics rom v12

Flashed this ICS based ROM and the compatible Siyah kernel ver. 1.53 (modified for SHW-M440S) to my 3G. Does not drain the battery much. Battery still remained 100% overnight with everything off. Used to have the Galnet modified MIUI ROM but the dev was slow to update. MIUI usually updates the ROM every Friday. RGUI updates his version the day after. OTA update is possible using the RGUI kitchen included in the ROM.

Apparent increase in speed/performance. I got an Antutu score of 4268 compared with a score of 3391 when I had a stock ROM. Quadrant score is also higher than stock ROM.

Hey guys, I just converted a kernel for SHW-M440S

SiyahKernel S3-v1.7beta1.. It was released yesterday: October 6, 2012


I used to have the MI1 Plus and it uses the MIUI ROM. Dual booting is built-in and both partitions also shares the same data. Just like the Siyah kernel, you can't mix different Android versions. Can't wait to flash this kernel but I have to wait until the dev updates my current ROM (RGUI MIUI) to JB. He's just waiting for the official JB (UK version) to be released.

---------- Post added at 02:41 PM ---------- Previous post was at 02:36 PM ----------

Yes! I installed Omega 27.1 and logged into the dropbox app and they gave me 48gb free for 24 months :)

Yep, I got it too. It's a free offer to S3 owners, I believe.

sorry guys.. false alarm.. Perseus kernel, and Phenomenal kernel is not convertible yet.. :(

But anyway, since harunjo the dev of [KERNEL Jelly Bean] GalaXsih v1.0 was kind enough to give me personally the latest and stable version of his kernel before releasing it publicly, I may be able to convert it ;)

EDIT:
I had converted it but it is stuck on bootloop :( *sigh

If you can wait another day, and IF Jelly bean is really out by tomorrow for this device, then you will be able to download the latest pre-rooted stock ROM shortly after its release (including SMS limit change).

Here is my adaptations for SHV-E210K:

CWM Recovery:
- Based on Chainfire's CWM recovery v6.4
- Fixed bug in original CF-CWM where it's impossible to restore backup if one of tar file bigger than 2.1GB.

Install it through ODIN. Choose E210K_CWM.tar as PDA part.

CWM Manager + busybox + root
- CWM Manager version for E210K/S/L. So, now you can make backup and restore it very easy! Just like on GT-I9300 version.
- most complete busybox version
- SuperSU as root manager.
Although it's compatible with any SHV-E210 version, there is no CF-CWM for S/L yet. Thus u need to use some other recoveries to install root and busybox (CWM Manager won't work without CF-CWM Recovery)

Install it through CWM recovery.

Everything here is compatible with any existing ROM version for E210K.

When i tried to flash the zip throug recovery, signature verification failed message always appear. Is there something wrong?

How did you update the firmware? im completely new. i downloaded the ALIA firmware for my SKT s3 and i tried to flash it through CWM but it didnt work
dont think its flashable via CWM. i never tried that before but i've always flashed new factory firmwares (or any firmware for that matter) through odin. download odin v3 and choose the file you want to flash after clicking the PDA button and then just press start. make sure you are in download mode (turn on the phone by pressing volume down, home, and power at the same time). let us know if you have any other questions.

and also, yeah the JB rom isn't available yet, although i heard that it was supposed to start rolling out in korea today. i find it strange that they updated an ICS firmware update a week and a half before they were supposed to give the JB update..but maybe it's just a sign of samsung staying on top of their sh*t these days!

    Proxyme Rooting

    Proxyme Guide


    Pre Rooted stock ROMs

    (Flashing the following ROM components will trigger the custom binary counter)
    Kitkat 4.4.4

    E210KKTUKNI3 (Proxyme) (Build Date 2014-09-12)
    • This zip archive contains an Odin flashable file. It is not the complete stock image, so you MUST have KTUKNI3 already running on your phone or you will need to download it from the above reference sites, which carry complete stock firmware images, and flash it before continuing with this file. Instructions are included.
    • uploaded.net
    • torrent, mirror2

    (Flashing these ROMs will NOT trigger the custom counter)
    Jelly Bean 4.3

    Rooting Instructions:
    Default state is - not rooted - Proxyme has been included in this rom,
    Proxyme offers live su binary control, and without the need to 'root' the phone, you have...
    - SSH server with virtually unlimited user accounts, configurable with specific UID, GID, home directory and shell,
    - execution of scripts with elevated privileges (sample debloating script included),
    - tag along scripts for root ON and root OFF actions,
    - busybox switch

    E210KKKUGND3 ( 2014-04-29 )
    If you experience problems after flashing, please consider wiping data/cache in recovery mode before posting issues in the thread. As usual, it is highly recommended that you backup your data before flashing this firmware image, even though it will not implicitly wipe data/cache partitions.

    E210KKKUGNA3 ( 2014-01-22 )
    Backup your data before flashing this firmware image, because it will perform a factory reset and wipe the cache and data partitions.

    E210KKKUGML4 ( 2013-12-12 )
    Backup your data before flashing this firmware image, because it will perform a factory reset and wipe the cache and data partitions.
    Rooting Instructions:
    Default state is - not rooted -. To root, create a file (can be empty) in directory /sdcard/Download/ called rootme and reboot the phone. As long as that file exists, your phone starts up rooted, remove or rename the file and root is no more. You get access to the su binary and thus root access, but SuperSU is no longer included; install it from the Play Store.



    On Ice (Due to hotfile shutdown, minimal support for older firmware images)

    Jelly Bean 4.1.2

    (1) Press VolumeUp/VolumeDown/Power simultaneously for a brief moment to toggle between root/unroot
    This toggle only works if you enable Settings->Developer Options->USB Debugging. This video demonstrates how the toggle works
