Hello.. Being updated to the latest firmware version is better than leave you left behind. By the way, you may downgrade to the previous version by flashing it via Odin. MIUI is custom ROM and not recommended for most user since it could make your warranty void. Thanks

If you flash with ODIN, yes. Just keep your modem XXEMG4 or greater, and you won't have a problem with whatever ROM you choose to run.

How to keep modem i have ugmk6?

[Q] Keep root when upgrading FW via Kies?

I have rooted my device and have the nordic LE8-firmware from May. Today I noticed via Kies that there is a new firmware for me, LF5.
Do I keep root if I upgrade via Kies? If not, how do I keep root? (is it possible?)
Thanks in advance
You cant i think

Just root it again. Takes less than a minute.

Or just flash a custom rom built from the latest firmware in the firstplace

How to install cm9 on sgs2 gingerbread?

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.
Sent from my GT-I9100 using xda premium
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
Sent from my GT-I9100 using xda premium
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] 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.

The i9300 doesn't have a 4.4 firmware, you are trying to brick your phone by flashing the wrong model.
Ok thank u so much
