How to install cm9 on sgs2 gingerbread? - Galaxy S II Q&A, Help & Troubleshooting

Just a question. There are numerous sites on the internet that tells you how to install cm9 on sgs2. Others say that you dont need to flash a leaked ics. Others need you to install . Please help thanks.

Go by the guide on CM9 website. I played it safe and flashed the tar version via PDA in odin. Once that's installed you can then update to latest nightly. I've never had any issues with that process. All the best.

So sir did you install first a leaked ics or not? Thanks

Erm not sure I'm a bit of a flasher- holic. More than likely I was on a 4.0.4 based custom rom. If you do full wipes and format system then flash via odin I'm sure you will be fine as that's what I did. Please read CM9 guide though.

[Q] Happy year!!! one question about flashing CM9

Hey guys:
I'm now running Galnetmiui with siyahkernel which comes with CWM recovery V5.5.0.4, Can I flash codeworkx's cm9 directly via CWM? In his thread..he just states ''Make sure you're running a proper working CWM like the one from CM7''. And after that, Can I restore my Backup using CWM?
I'm sorry if I repeat the question!
Thanks in advance
Yes, that should work fine.

Additionally, should I have wiped my data/cache and dalvik cache when installing a new ROM?

I dont have a computer....i need a flashable one through recovery
Sent from my SAMSUNG-SGH-I717 using xda premium
Saurom is your only flashable GB build in this section..
Check the super thread at the top of the general section, and scroll down to the roms.
Read "carefully"....before flashing...
Saurom is a loaded version of 2.3.6 with many extras ....I like it ...g
Hmmm. Do you happen to have a backup of your stock ROM (gingerbread). From before you flashed a custom ROM? If so then all you need is the stock kernel and modem. I have a flash able zip for the stock recovery I can give you, but no longer have the kernel and modem on hand.

I dont i bought it with ics already on it

Well, your only other option is trying Saurom. Its about the only GB ROM you can flash. Otherwise you'll need to find a computer you can use to use Odin and follow the steps in the link I posted above.

Rom Manager might be able to help.

Ok time for some research

Using rom manager app you should be able to get latest cwm which you have already.
I would try out cm10.0 stable

[Q] Omega Rom - Mobile Data hangs the phone

Hi
I am using omega 4.2.2 latest built. The phone gets stuck/hanged whenever I connect mobile data. Sometimes it works fine but stucks when I use twitter or Facebook app.
Why is that so?
And can I downgrade to omega 4.1.2 ?

Try a different baseband
Sent from my GT-I9300 using Tapatalk 4
Don't know much about the basebands. I think every rom has a different baseband. So you mean try some other rom ? Stock or custom ?
Sent from my GT-I9300 using xda premium
Alright did some research and yes I got the idea. Its baseband problem. I am gona try XXEMC6.
But can I downdowngrade from jb 4.2.2 to jb 4.1.2 after a full wipe?
Sent from my GT-I9300 using xda premium
Why are you downgrading the rom? I said try another baseband. Not try another rom.
Sent from my GT-I9300 using Tapatalk 4
Because I cannot find any other than XXUFME7 baseband for jb 4.2.2
I thought it came with only one baseband.
I checked wanamlite and omega. They both come up with XXUFME7.
Can you recommend some roms ?

My point is you can use ANY baseband. It is not tied or related to the ROM in any way. There's hundreds of basebands available to flash in the general forum.
Now you are making sense. So I had to install the rom first or the baseband first then any rom?
Baseband and a kernel is the same thing ?

Please follow the link in my signature to general > sticky roll-up thread. Read "Understanding the basics before rooting". I put a lot of effort into answering all your questions in advance there. Please read it, you'll find it very informative.
Changed my kernal using omega v47
No freezes anymore. The 4.2.2 kernal is so unstable.
