[Q] What rom to use? - Galaxy S II Q&A, Help & Troubleshooting

My phone is rooted now and few friends here gave me suggestions of siyah and some...i want to know if I can directly flash the rom from stock recovery mode..i downloaded ROM manager, but it only has clockwork mode and cyanogen i guess.. can i do that using siya?

You need CWRecovery on your phone (sounds like you used a root method that didn't involve using a kernel with CWM if you only have stock recovery). Best way to get it is to flash a kernel that has it built in - Siyah, Dorimanx, etc, etc. There's a number of them; search the development sections of the board. Once you've got CWM on, you'll be able to flash any rom you want.

Siyah is a kernel, not a ROM. And no, you cannot flash a custom ROM from stock recovery. Search for rachmat3's rooting method and use that. Or flash the tar version of siyah or dorimanx via Odin.
ROM manager seems to have some issues with the S2. try to avoid using it as far as possible.
See which ROM you want to use. If it has the new Mali drivers use dorimanx 7.4 else use siyah 4.1.5

Siyah is a kernel developed by gokhanmoral. ROM on the other hand is also called firmware, you can flash them both in clockworkmod recovery, but cannot be done in stock recovery.
As for ROM manager, I've seen people brick their phone using it, so just stick to flashing clockworkmod recovery.

Don't use rom manager, unless you want an expensive brick.
And Rootbox with dorimax is a good combination you can check out

If you are using siyah kernel you can tweak the GPU steps and overclock your CPU using an app called ExTweaks. But note you are not going to get any serious performance boost, your machine tends to be what you have.

Installing Clockwork recovery

So I'm rooting my friends phone for him and planning to install villianrom.
So far ive rooted via zerg exploit.. All went well, after I downloaded ROM manager and install clock work recovery for "Samsung galaxy S 2". Rebooted into recovery and it took me into stock Android recovery, which of course means clockwork didn't install..
I've been doing some reading and it seems tho ppl install the tweaked kernel with root and recovery pre applied.. If there no way around going that route? I mean the phone is already rooted, can't I install clockwork some other way.
Also if I dont have any choice and have to go through the flashing pre rooted clockwork kernel through Odin. Suppose I install a ROM with a custom speed kernel, will I loose root and clock work since it's pre applied to the stockish kernel I flashed from Odin?

No

Most roms have CWM anyway read the install instructions

No

Original = built from sources. i.e. CyanogenMod for an example of a ROM, or Siyah for a kernel.
Regular = derivative from something else, i.e. many ROMs out there are usually derived from stock, with themes and such.
Just apply cf root specific to your phone base and flash it in the PDA section of Odin, it will re root your phone with cwm recovery, then place the villain from or from of your choice in the root of your SD card and flash it with cwm, any problems let me know

Help with stock kernel to root, and CWM.

Hi, is there a completely stock kernel with root and CWM that I can flash with Odin, on my S2. I have seen a couple kernels but they have things like different boot animations, and different little tweaks but I just want stock ROM with root and CWM. I have never used Odin before, and was also wondering if rooting,and installing CWM with Odin is safer than using SuperOneClick, then using Odin to install CWM? Any help would be appreciated thanks.

1. stock kernel with root? Yes.
2. stock kernel with CwM (and root)? Probably yes.
Read this thread: http://forum.xda-developers.com/showthread.php?t=1285823
I have not personally gone with that option and I believe most of members here do not go with this option. So, I don't know if it works as expect or not.
3. custom kernel with CwM? Yes. So far in this room, there are 2 most popular custom kernels, Entropy's Daily Driver and Siyah kernel.

Please Help

Hi,
Thanks for the unbelievably fast reply. Yes i did add CF-Root-SGS2_XW_OXA_KK5-v5.0-CWM5 as a PDA option in Odin. I followed this guide http://androidadvices.com/root-samsung-galaxy-s2-gt-i9100-xwkk5-gingerbread-236-firmware/
should i do it again?

Hi,
Problem solved. I flashed the CF-root and tried the 3 button combo to go into the recovery but no gain.
What made it work was that i started the CWM app and went into the recovery from there. That made it work for the 3 button combo as well.

[Q] Able to flash kernel if phone is not root?

Hi all,
May i know if i am able to flash a kernel like "siyah" on an unroot S3 by using the default recovery mode on Samsung S3?
If yes, are there any implication as the user does not wish to root but hope to have a better kernel.
Thanks.
Siyah is rooted kernel if you flash custom kernel all kernel is rooted.And you wil flash whit Odin nhot stock recovery.
Sent from my GT-I9300 using xda premium
no you cant,
if you have not rooted and CWM not installed, only throgh odin
major kernels are coming with auto rooting..
Even if i were to use the press vol up button with menu and power key to install the kernel from there, it still wont work?
Its Kernel and not ROM... so must i still use Odin?
Yes Odin is your friend.Feell the power of Odin dhont scare.1 go and learn haw t use Odin in Dev section

Wrong kernel can be flashed via Odin without root if in the correct TAR format see stock rom thread .
Custom kernel likewise if its in TAR format .

You can flash PhilZ-kernel with built-in CWM recovery. Have a look at PhilZ-kernel thread to find the appropriate kernel for you.

In http://forum.xda-developers.com/showthread.php?t=1877270 you can find your appropriate kernel, but you need to choose the right one, because the latest kernels are for JellyBean only.
No, you don't need Odin/heimdall and you don't' need a PC even if it's better to have one at hand when it comes to issues.
One hint: read and try to understand everything before flashing. If you are unsure, ask, otherwise there is a chance to brick the device, especially with 4.0.4 stock (-> brick bug)

okay thanks dude, but is there a safe one even if with a PC, I'm used to rooting and flashing recovery mods and kernels using PC and odin for my s3 and it is very safe and no chance of bricking the phone, so is there a similar way for s2 ?

thanks a lot bro, will give it a try today
btw im going to flash the latest jellybam on i9100 so will siyah have any problem regarding the ROM ? i mean will there be any lag or something ?
CWM matters, not the kernel you're actually on.
Of course if you're on 4.0.4's kernel you can't wipe.

The Siyah kernel will be overwritten during the jellybam flash anyway......so as mentioned. ...the kernel doesn't matter/won't cause compatibility issues
