The fix is simple, all you got to do is flash siyah kernel using odin. If it doesn't work, let me know

Modem I9100G compatibles?

Hi people, I use to hace an I9100 but went brick, so Samsung decide to give me a new S2 but now I see that is an I9100G. i've being reading and I realize that all files between I9100 and I9100G are not compatible. I used to hace a nice and well working modem in my I9100.
Can I put a I9100 Modem to my new I9100G or is incompatible?
Thanks for your help. :good:

Used the search tool but nothing about it.
I'm looking for a list of compatible modem for I9100G with AOKP based rom too.
As soon as I switch to a custom AOSP/AOKP based rom, I loose my data connection. And it goes well when I go back to a stock rom..
Tried many roms with all the ways possible for flashing etc.. but still stuck on this ****
Same question... I have CyanogenMod 10. Is it compatible?
Thank you.

Modem KK1
Yup KK1 good enough for me very consistent

weird. it's supposed that you must have data connection since first boot when you installed stock ROM.

for the first time I booted using the stock modem, sometimes the signal is not very good, so I tried to install KK1, until now, the modem is working properly

Network issues

First of all HI to everyone. This is my first post on XDA so if I messed something up dont be too harsh..
The question is: My S2 every once in a while losses network. Sometimes it happens during calls, or sending sms, browseing... If I remember correctly it didnt happen while I was on gingerbread. Any ideas? If yes please point me to the right thread.

If it was me Id try a few combos to see if its software or hardware.

Ics with getril/without getril
Personally I dont like getril.....
It's because of siyah kernel. Use newer version of siyah, this one does not dropped calls.

OK, which one should I get than??
DorimNx 5.92 is perfect.
Siyah latest 5.0.1 is good, but high battery usage.
Latest dorimanx v7.xx had low 3d scores....
I suggest dorimanx 5.92 plus xwlq3 rom, not an single dropped calls.

Updateing siyah did the trick. No sudden call drops or lost of network since I updated.

[Q] I messed up! :( *Flashing help needed*

I really F'ed up.
I was running ICS on my bell Galaxy S2 but I wanted to try the S3 rom that was released here. (Note that I am somewhat a stupid when it comes to android flashing). I installed a CF-root kernel (phone wasn't CWM at the time) but the phone didn't turn work - it would go to black screen.
So I tried a couple different kernels, nothing worked. Then I went crazy and flashing just about everything. Nothing has changed.
When I turn the phone on, it gets stuck at the Galaxy S II screen. When I go to download mode, it is like usual (no CWM, the standard one). And when I go into recovery, it says "Forced Upload, by key pressing".
What can I do now? I would like to just get the phone working at this point, official firmware that works with kies would be nice. S3 rom would be even better.
Whoever helps me solve this would be my hero. Serious.
EDIT: I am now on clockwork recovery if that helps.

Thank you so much. The phone works perfectly now!
If you know how to get it to the S3 rom (or just get the cool gesture features) that would be nice but if not I'll be happy on stock ICS until I learn a lot more about flashing.

Too late, I already did. It works really well except most of the new features (motion and all that) is missing .
Still a good ROM though. To clarify, it's the S3 ROM that was modified to fit the S2. I found it through google.

Network Carrier problem

hey, guys
I work at KSA
When I was using ICS 4.0.4 Pakistan , when any one call me he hear "the phone you calling is switched off, try again later" and my phone in open at all time.
3 days ago, I downgrade to ICS 4.0.3 KSA till now no problem in receiving calls.
Is this problem from rom, as Modem in each rom different from country to other?
Now I want to flash Cynogonmode rom 10.1, Will I face this problem again?
thank you Guys

it all depends on the Modem that comes along with the Firmware and will be diff for diff regions ma8
Just check the modem that u have (with ICS 4.0.3) for now which is wrk'ng fine and note it down.
After flashing CM10.1 if u face any netwrk issue then u can use that modem again(which u can find in the link HERE)
