New Jellybean 4.1.2 leaked today, and man is it clean!

All you Galaxy S2 Power users out there - come and get it!
This build is very much near perfect so we believe that Samsung will actually start rolling out the Official Jelly Bean update for the Samsung Galaxy S II very soon. The day Samsung starts to roll out the official update you will be able to install the latest update through Kies or OTA update.

Some of the Enhancements in the new Jelly Bean Update:
- Buttery Smooth Performance & Great Stability (Thanks to Project Butter)
- New TouchWiz Nature UX (Same UI as of the Galaxy S III and Galaxy Note II)
- Samsung’s Cloud services
- Direct Call, Smart Stay and Pop-up Play Features
- New Widgets From the Galaxy S III
- 2 Home screen modes
- New Notifications bar
- Google Now

This is a PRE-RELEASE version so not official from KIES.
As this is a PRE-RELEASE firmware so expect some minor bugs.

Firmware Details:

Oh yeah, I will check up to see if any of you have any questions...

Enjoy

will this work for a epic 4g touch version

Hi Rondell, not sure. In the release notes it does mention that this is a European release. The phone nomenclature for this release is Galaxy S2 GT-I9100. If your phone is the GT-9100 you should be good to go.

note- Sammy releases often to Eurpoe first but the other countries come out pretty quick afterwards.

Good luck.

What about at&t Samsung Galaxy SII (SGH-i777)??? Will it work with it??

Aayush, I don't think so. I know that the SGS2 is unbrandable. so you can remove branding. But I believe that you have a different model.

I'm sure the final is coming soon and will be rolled out to the US and Asia..

am downloading now wish me luck

Good Luck ! Do you know how to use Odin? If not look it up, easy but need to follow the proper steps.

I have a Samsung Galaxy S2(SGH-T989) is it compatible with this because I didn't see my model on the list? Also, is this for rooted phones?

Hi Joseph, no, sorry, your phone is not compatible. Yes this can be rooted

is it compitable with I9100g ?

Taken from Samsung Wiki page......

"Galaxy S II - Model GT-I9100G
The Samsung Galaxy S II GT-I9100G was released in late 2011, and is usually sold instead of the original GT-I9100 in certain markets (mostly Asia and some parts of Europe). An overview of the Samsung Galaxy S II GT-I9100G can be seen on Samsung's official website.[67] It features a Texas Instruments OMAP4430 SoC instead of the Exynos in the GT-I9100. It is visually identical to the GT-I9100, as well as having the same 1.2 GHz processor speed and dual-core ARM Cortex A9 processor technology. However, the CPU processing core is of a different design and the GPU is replaced by a PowerVR SGX 540 graphics processor. While practically equivalent, the different SoC makes this variant incompatible with custom ROMs intended for the I9100. It has gained support for aftermarket firmwares such as CyanogenMod 9.[68]"

But don't quote me on it... Chris would probably better answer your question

I believe that the i9100g has a different chipset. So I would say no.... But I am not sure. I'll try and find out though.

THANKS alot for the explaning..
That's helped me alot..

I am a GT-I900G user in India. on 24th of November I got a 4.0.4 update from Samsung as FOTA. will I be getting an official JB update from Samsung now ? pl answer. I love my S2 and Jb. One more question - after installing your rom if Samsung rolls out official JB update to me , will I be able to install that. If yes how ?. Thanks ALOT !!!!!!!!!!!

SAK, sure. You should receive the final when it comes out to your area (India-Asia).

By the way, you can install any firmware that is designed for your phone by using the Odin tool.

You should find all the info you need here:

If I install this version of Jelly Bean, how do I upgrade to the official release version when it appears? Do I have to get back to 4.0.4 or I can upgrade directly?

Paul, no you won't, you can simply update the newest firmware just like you did this one. Also this is original Sammy. So no problems there.

Many thanks!
Installed already. It's amazing. I'm in love. Just like a new phone.

Cool, Paul, glad it worked out for you.
