[Q] I9100 No Mobile Network Coverage Indoor! - Galaxy S II Q&A, Help & Troubleshooting

Hi,
recently I flashed the most recent nightly cyanogenmod into my I9100 phone. In the areas it used to have moderate mobile coverage now having zero coverage and the mobile says "No Service". I am based in Saudi Arabia and my baseband according to my phone is i9100XXLLPX.
I even tried many other firmware but the problem persists.
Thanks

Yes it does, flash a new modem.
If you get signal outside well....that's a different story.

[Q] Best modem for AT&T?

Just wondering what the best modem is for ATT and some other question about modems.
Right now im running wanam lite kj1 5.6 with ICS domination theme. I have KI4 modem flashed because i was on villanrom which i might go back to because it has better battery life.
Does the modem affect the ROM in anyway? just wondering because most roms have a modem prefix to them on the development forum. or is there a certain modem better in every senario?
Thanks for your help!
I too would like to know the best modem for at&t. My current one (Current official uk unbranded) seems to completely lose signal after a phone call or just randomly, it quickly reestablishes connection but still annoying.

Have you tried Odin to push the uckj4 leak modem for the i777? All the 9100 modems I e used on my i777 turn the radio off when a voice call occurs then reconnects after call fails.

Maybe i9100 modems just dont work on i777 and vice versa. Hopefully someone could correct me but i guess its worth a try. Is it better to flash modems via odin then CMW? and another question whats the difference between a modem and a kernel? I know on some level the kernel has something to do with the firmware and the modem has to do with the baseband, but im still unsure about the difference.
Thanks again!
Also have the same problem. The 3g lost the signal randomly. my baseband is "UNKNOWN" . Any idea?

I'm assuming these guys are running real I9100s on AT&T (otherwise they're in the wrong forum) - pushing an I777 modem will likely completely break them.

Hey, did you ever find out the answer to this question?
I want to know what's the difference between flashing with Odin and CMW, is one do more than the other?
yea.. anyone?

I'm on baseband XXKI3, running my I9100 on AT&T... don't have any issues. No call drops, no signal drops after calls are done, etc. Works fine.

Funny - I have XXKI3 as well on AT&T and periodically I get drops and it's almost always just as syncing is initiated.
@robsw
I noticed you are located in Chicago. the problem could just be that AT&T sucks horribly in the downtown area. specifically anywhere near River North or the loop. I have tried just about every available modem and I still have data connection issues in those areas. Even friends with iPhones comain about poor data in those areas.
I use the ki1 modem on my I9100 on at&t in louisiana. Ive found this modem gives me the best signal in my area. I did use ki4 for a while but i kept getting dropped calls inside my house. Now with ki1 no more dropped calls

I live in Champaign,IL. Data drop/hang issue always there on KG2, KI3, KI4 modem. I had data issues even I have full bar of signal. But I do realize that data drop issue is location related. Every time I go to the same place, I got slow or data drop problem. Ha! maybe something isn't configure nicely between the tower and our S2.
yea, I was in Chicago this weekend, kept turning on Airplane mode and back on..
at&t is making me pretty mad.
GT-i9100
4.0.3
Baseband version
I9100XXLPH
XXLPH Kernel as well.
I am in Colorado and my service is great. I dont have much experience with the GB radios because as soon as I got the phone Iw ent to ICS and never went back
It may be worth checking the sticker under the battery to confirm the phones version. In Australia, New Zealand, Israel and some other countries they also sell the I9100T which is just the same as the international version but works better on a T model modem. There are plenty of them linked in the Aussie thread in general.

I'm in the North suburbs. This most often occurs when I'm driving. The call will drop and more often than not, when I glance down at the phone, data will be syncing.

[Q] Galaxy SII i9100 (Poor Signal Strength)

Hey guys,
I'm using Resurrection Remix ICS 2.4 and I am experiencing a very low signal strength on the network 3 in the UK. One of my friends are using the same carrier with his galaxy s2 and rom however he is getting full signal and I am only achieving 1/2 bars and 3 outside.
What can I do to fix this problem?
Thanks,
izMarioZz
Try comparing you and your friend's 'About phone' in settings. You might have a signal problem because of your phone's Baseband version.
Try a different modem. The best version for me might not be the best for you. KH3 is a good modem to try.
Chris.

Thank you Chris, I'll install the KH3 Modem and I'll get back to you on if it works or not

I have checked that the baseband version is the same and it wasn't, however, I installed the XXKPA modem that he was running and i'm still having the same problem :/

Which modem to flash?

Sometimes, mobile data signal is very low. It varies from excellent Hspa to minimal Edge... I suppose this is is somewhat due to modem I'm running. It's DXLPA that came with Wanam 12.1.
So, which modem would you suggest to flash? That has a stable data signal reception?
Sent from my Galaxy S2 GT i9100
Modems are location and carrier dependent, you should try to test...
However, ask to other peoples won't help you so much, 'couse the best modem for "Herry" from Liverpool could not be the best modem for "James" from London....this is just an ex, the point is that tha network signal depends and changes of quality from place to place....
Edit: here a lot of modems---> http://veyka.co.uk/radios/

Kernels and ISP issues.

Soooo... Have had a good look and dig about and can't find any answers, I'm fairly new to xda and still learning as are many about rooting/flashing and the problems along the way.
My problem here is, when I flash a kernel for Stweaks, I loose my ISP. I live in the UK and the message 'ISP outside of your location' or along those lines appears when I'm trying to use TVCatch up or any app that can be related.
Can this problem be addressed with a kernel flashed, or is my only option to remain on just my ROM and its stock kernel?
Gt-i9300 no carrier, CM10.1, (most kernels tried).

Lose ISP you mean your ISP goes offline ???
But surely your ISP is your internet service provider not your mobile data network .
Or do you mean you lose Wifi Network ???
My guess ignoring above is that its a CM problem as stweaks does not give that problem on samsung based roms .

no, not wifi... ISP.
its basicly saying im not in the country that my ISP is in, or that my ISP is outside of the country i am in, even tho non of this is true.
it only happens after flashing a kernel, otherwise on any rom i have tried, i have no problem, until i flash a kernel.
i dont understand why, and i am a 'noob' in many senses. sorry if im being difficult to understand.
Are you near the south coast (I presume you are English if you are using tv catchup)

yes i said i live in the UK in my original post, but more to the point, the north of england.
Ok, I just wondered as I have heard people on the south coast locking onto UK providers that have bases on the north French coast and ferry relay bases, or something along those lines

ah right, no i guess thats not my problem here then.
i like to underclock my s3 for obvious 'life' reasons but i do also like to watch abit of t.v when travelling or at work travelling.
could i resolve this issue with a dual boot?
ive been tempted to try a dual boot but havent yet looked up on dualboots as my mates SII is sadly looking soft bricked so thats been the priority for the past few days. my head cant manage too much at once when doing 'paperwork' i.e reading up.
im guessing the kernel on a dual boot supports both roms?
is this just a unique problem in my case?
I'm on PAYG t-mobile in the East Midlands. I use tv catchup and it works fine, both on wireless and on data connection.
I use LiquidSmooth ROM 4.2.2 with siyah kernel. I also have Paranoid Android 3.0 and that also seems to work fine.
Do you have an international S3?
Does your phone have any branding?

Mobile network strength problem

Hello!
I have problem.
I have galaxy S2 with stock rom, and the phone comes from UK. I have pretty bad mobile network signal in Latvia. Comparing to some other S2 phone, it had better signal strength.
My guess would be, that some Frequency's are different. I couldnt find which phone builds are meant for which countrys, and couldnt get list of supported Frequencies.
My phone build nr. is "JZ054K.I9100XWLSD".

I meant that you're right, OP needs to flash a different modem.
I've added that he/she needs to flash the same modem as on the S2 with the good reception.
O ok cool. Sign may not be as good if on a different network or maybe it's his network that's slower than his mates network. But yes good advice and open should do that :thumbup:
