Great thread, I think it would help if there was an explanation for roms, kernels and themes. I honestly don't know what a kernel does precisely or how to differentiate between them when choosing.

Thanks for the thread though, helped me choose my current setup:

rom - Juggernaut 3.7

kernel - Bullet 2.9

theme - ICS complete package 2.0 for Juggernaut 3.7

anyone know how to remove that synergy kernal from bootloader?

Im still not understanding the difference between Kernels and Roms? Can you clarify please.
[T-Mobile Samsung Galaxy S II SGH-T989] joking:
kernel = car engine

ROM = car body

theme = paint
[T-Mobile Samsung Galaxy S II SGH-T989] DesignGrits:
I guess my question is more....the roms already come built in with a kernel though, right? There is no need for me to download a kernel to root and load a rom, right?

Also, with this process of rooting and loading a rom through ODIN, do I root the phone first before I load CW-RECOVERY? I would assume so, but the instructions on the general discussion page says the opposite.
[T-Mobile Samsung Galaxy S II SGH-T989] fsmith01284:
Could you update and include new roms and kernels. If you could include some benchmarks that would help us to figure out what it actually improves. Great work!

How to Root 2.3.6 - Build GINGERBREAD.UVKL1?

T mobile is rolling out the new version with Wifi Calling. Has anyone successfully rooted this new version? I noticed after the update my root is now broken. It is so new I have not found any tutorials on the web and the previous way that I rooted is broken with error "Cannot copy boomsh.: Permission denied"

[T-Mobile Samsung Galaxy S II SGH-T989] mintharis:
1) use Odin to put cwm on your phone

2) from cwm flash su zip to get root access

Simple as that. From what I've seen most ROMs will come with a kernel to ensure it boots properly. From there you can flash your preferred kernel.

2. As far as I know, you cannot flash a new kernel without having root access and an unlocked bootloader.

3. Root, get a new recovery, then install your ROMs via this recovery. Clockwork Mod Recovery is the law of the land.

Juggernaut tweak transfers.

Just and FYI...I used Juggernaut 4.1 and customized everything that I liked with the MIUI battery bar and tweaked the colors. I did a Titanium Back Up and when I flashed a new ROM and recovered by back up, all the tweaks from Juggernaut 4.1 came back on top of a ROM that did not have ROM Tweaks. Strange, but they all still worked. Has anybody else seen this happen for them?

This isnt the first time i had hardware interface issues with my pc.. Was womdering if anyone thats on a old machine running XP could help me out?

This entire post is two years old, is it up to date?

I am looking to root my T-mobile Galaxy S2 T989. I live in the U.S. and just had my phone unlocked by samsung. I'm looking to root my phone and also make sure I've found a reliable un-root method in the event I need to un-root at some point. I came to this site and noticed the site was last edited some two years ago. The link to download the clockwork mod is broken, yet the other files were downloadable. My concern is, one - am I getting the most updated info here, two - are these files i'm downloading the latest versions, and three - why hasn't anyone posted to this in two years. I want to make sure I'm getting current info in regards to rooting my phone because I don't want to brick my $600.00 investment. I just recently had samsung unlock my phone through T-mobile and i'm ready for the next step. My phone is an American T-mobile Galaxy S2.

Model number SGH-T989

Android Version 2.3.6

Baseband version T989UVKL1

Kernel version 2.6.35.11

Build number GINGERBREAD.UVKL1

Please help me find a reliable site to get updated files to root my phone. I tried xda-developers and the androidforums.com which basically leads to the xda-developers site. I'm worried about trying some youtube stuff and I can't find anything newer than two years so i'm worried. Please help.​

Installing Kernels

Sorry im a noob, but how would you install:confused: a kernel ? Can you use any kernel on any rom ?
[T-Mobile Samsung Galaxy S II SGH-T989] LoopDoGG79:
You would install by flashing it via CWM. Most definitely you cannot flash any kernel on any ROM. First, the must be the same Android version,GB or ICS. Second the ROM must be able to accept custom kernels. AOKP and CM9 have their own kernels.

Edit: AOKP and CM9 don't have their own kernels, sorry.

I'm not looking to go crazy on overclocking but I would like one that will extend my battery while at the same time be smarter on when to boost my clocks.

edit: I just looked at my kernel version and its says I have darkside installed already. Did the Rom I installed have it included?
