Try updating your modem (or radio) to KG3 or KG6 I haven't had that happen since I updated modem. Pulser has a modem thread in development. Flash with ODIN.

Thank you,
Is that kind of rooting ?
because i do not wanna root my mobile

I don't think you need root access to flash with ODIN. You would be putting official Samsung baseband on your device, so I don't see a problem.

[Q] Custom rom and updating just the baseband?

Hi Guys,
Im currently using CM7 nightly build 20 and noticed that my modem was still in I9100XXKG2
Now i hear the latest modem is KG6 and is supposed to address some battery issues.
How do I go about upgrading it without screwing my custom rom over? Previously before i popped on CM7, Samsung KIES would handle it all for me.
I have a i9100XXKG6.zip with Code file, CSC File, Kernel file, modem file and PIT file
Do I just use Odin in (vol down, home + power) to flash just the modem file and then re-root with superclick?
Thanks!
Easiest way is to use codeworkx radios in rom manager. You can flash that over your existing radio without messing up your CM rom.

There is a sticky thread with every radio, download the one you want and flash via odin
Or if you have rom manager premium they are all available via that.
Just so you know, the radio version that's best is very region dependant

Nice swyping. Tee hee.
Based on reviews in Rom manager I went for KG3 over KG6.. No complaints from me..

Sgs2 unlock/root and unroot/stock ROM update?

Hi..i have a Three UK network phone which i have unlocked using method described on xda...however I'd like to debrand it by installing another ROM and unroot...will i lose the unlock in this process?
Also, if i downloaded ROM from samfirmware, how can i apply using odin as there are a few files included? I'm not very technical when it comes to various intricacies of Android ROMs!
As always thanks for your help in advance...

You can flash any firmware you like, and later a csc to match UK or just enter the APN settings manually. XX UK or XE/XW European etc, but as I said, doesn't really matter. For best data speed, connection etc you need to then flash a modem that best suits your carrier. Best to just try.
For the latest modems, some flashable via Odin and in CWM recovery:

Hmm don't think so...
Never miss mind something about downgrade via Kies...
So only way is using Odin and flash a gb-stock-firmware...
Or u flash a kernel from here, wipe all, then flash a Rom...
CHEERS ;-)

No you cant downgrade by Kies. Use a custom rom or manually downgrade.
How do i manually downgrade ? .

No way via kies, learn Odin as sahibunlimited said and flash it, it won't take more than half hour to learn Odin and flash

Hey you are from x10 section
Remember me?
I didn't read your name when i was on mobile
Yeah i remember you mate. You was on the face book page alot aswell if i am not wrong . was on x10 section for quite a while now loving my s2 but everything seemed straight forward on the x10 where as here there seems to be so many different variables to have to check before flashing anything .

It is quite impossible to root without the phone, lower models can be done from the recovery but s2 will get bricked.
Using GT - I9100
I thank those who give helpful comments
I expect the same from others.
I downloaded temp cwm, flash it - without exit from cwn recovery flash wanam 12.8. Will it work?

Flashing stockrom from a different country?

Hello, I would like to ask something.
I knew that recently Samsung has released 4.3 update for Samsung Galaxy SIII International Version. The 4.3 update hasn't reach my country yet. I would like to know is it possible for me to flash another country's official frimware? Is there any negative effects?
Meanwhile, if I flash the latest stock rom back to my phone, will it be unrooted?
Sent from my GT-I9300 using xda app-developers app
Yes, you can flash a rom from another country -which includes a modem for another country. If the modem is unsuitable you will lose signal strength or even all connection.
Of course if you flash an unrooted stock rom then your phone will be unrooted, that's the whole point.
Unless you are confident in flashing modems and kernels I would not advise using 4.3 yet -it isn't reliable unless you can replace both.
Thanks for the quick reply
In that case, is it possible to flash just the ROM without the modem/baseband? (SamMobile ROMs come with seperate PDA, Modem)
Sent from my GT-I9300 using xda app-developers app
If your current baseband is EMGx or later then yes, you can flash just the rom.
Alright.
Thanks for your help
