[Q] Help! Galaxy SII on AT&T - Galaxy S II Q&A, Help & Troubleshooting

I have an international Galaxy S2 and I find that the reception on AT&T is terrible. Plenty of dropped calls and people can't hear me well.
I think it might be a problem with the firmware that I have on it.
Model umber: GT-I9100
Android Version 2.3.4
Baseband version: I9100XXKI1
Build Number: GINGERBREAD.XWKI4

Yeah that's quite old.. I'm using AT&T also. I'm using latest cm9. You should upgrade.
Edit: go to the bottom of post and get latest firmware. http://forum.xda-developers.com/showthread.php?t=1075278
Your looking for wlp3 I believe its 4.0.3

Which firmware are you running? THere are so many firmwares on that page, I don't know which one will run well on ATT.

Im using the latest and having no trouble. At least no problems with dropped calls.

[Q] ICS for GT-I9100T

Hi,
Does anyone know of an ICS ROM for the Galaxy S2 GT-I9100T model?
You can use any rom for the I9100. Makes no difference.
Just flash your i9100t modem back on ics works for me.
Sent from my GT-I9100 using xda premium
Hi, thanks for your reply.
I already installed an ICS ROM intended for the regular model, and it is very very buggy. The internet connection is very bad.
I did some research on the Web and what I understand it's a problem with the modem. The modem for the T model is different.
I'm in Israel on the Pelephone network.
Hi 7t
I wrote my comment just as you wrote yours, so I didn't see it.
From where can I download a modem for the T model?
Thanks.

wondering. thought that it would have, because of i9100T ,.. but apparently just orange UK (and france) have it. then you can install any i9100 you want.
I9100T doesnt mean nfc it is optimized for 850 mhz network.

As 7tOny4 says, the T thing is about the modem, nothing to do with NFC.
No NFC in Israel anyway.
Thanks anyway.
I have a GT-I9100T and have been using various ICS roms, including the CM9 nightlies, for the past month or so. At the moment, I'm running Resurrection Remix.
The modems included in the latest roms have all worked fine for me, so all I've had to do is re-add the appropriate APNs If for some reason it doesn't work with the included modem, just flash a modem file from your carrier or another local carrier that uses similar frequencies.
There's a collection of modem files from different carriers globally on this thread:
http://forum.xda-developers.com/showthread.php?t=1131950
With the official release of ICS today, I expect that we'll be seeing updates to all of the main one-off roms within the next few days, including updated kernels and modems.
I have a gs2 i9100T and running remix ICS 9.6. It is fast, smooth and stable.

You have a very old Gingerbread baseband from september last year. LPS works excellent, I'd give it a try.
Downloading LPS now from this thread
http://forum.xda-developers.com/showthread.php?t=1131950&page=105
does Vodafone has any different modem for SGS2?
Still facing same issue upgraded modem LPS Its still the same.
Strange thing is Use 2G network and Data Enabled is unchecked itself whenever I had this problem.

Best way to find a good Modem is testing them all.

You need a computer and a thing called search and you look on XDA thread for Modem post with flashable modems .Like most stuff its found in development .
But you would do better to read the basics first .

I777UCLD4 4.0.3 how to root

I have been bouncing back and forth between 2.3.6 and 4.0.3 and wish I could figure out a good way to root my ICS 4.0.3. The things I have tried from here have all resulted in failures and having to rollback to 2.3.6 rooted. I hate all the voice recognition software and would love to get rid of it so rooting is my only options, I think!
Please help if possible.

So your phone is not a galaxy s2? I believe you have posted in the wrong direction
Sent from my GT-I9100 using Xparent Blue Tapatalk 2
Go to the AT&T Galaxy S2 Forums. They can help you. The i777 is the AT&T Galaxy S2.
Yes my phone is a Samsung Galaxy SII
There seems to be some confustion. First make sure your phone is an I777. Look under the battery.
I777UCLD4 was a pre-release leak. The officially released version is I777UCLE5. Do not install UCLD4. Go to the development section and get UCLE5 Stock ICS plus Root.

Check/ask rom thread re same problem and modems first as its 99% not a warranty problem .
Warranty void anyway with root and custom rom .

Pretty sure the problem is that your modem is incompatible with your firmware. On the S3 the newer roms require a newer modem specific to the firmware.

I've experienced this for the past three days too. Stock OS, latest UK version.
The only workaround I've found is to use the Speaker but this is hardly satisfactory. I'm about to do an (inconvenient) factory reset to see if it cures this and other issues.
change modem

Well three customer service also suggested to use speaker. But let's me honest no one buys a phone just to use a a speaker.
About changing modem version, can any one sugest to witch one? For Omega 9

If you are running XX"B"___ firmware, apparently you need to match your modem.
Check post #2 of my modem thread for modems to try
Sent from my GT-P6810 using xda premium
Well omega 9 is based on blg1 firmware and the modem which ships with blg1 is lf3 so it sounds kind of odd you have phone issues when you are using matching stuff.
Maybe try blfb modem since its compatible with omega 9/lf3 and is the modem designed for the UK.

Yeah seems odd if modem DXLF3 is already packaged with the ROM.
And there are other "B" modems to try as well, all documented in post #2
Only takes minutes to test.

[Q] Need help quickly!

I know I'll probably get crap for asking, but I'm clueless, and I need this phone working tonight. Which modem is better? In Ressurection Remix, I'm running XXLPS. But UCLE5 is newer. Which is better? I truly do not have time to thoroughly test each one, and we are heading to the middle of nowhere Minnesota in the morning.
I think XXLPS

And then it turned into the randomest conversation ever and people calling each other potheads? Modems are all based on location. I doubt they help too much if you are going out of service.

You can download all of them and bring them all with you. If one works, roll with it. If it doesn't, try the next one. Takes 2 minutes Max to reboot to recovery, flash the modem, and reboot. Stop when you find one that works.

Where'd he even get a modem for the I9100 though and why would he flash it on an.I777? Unless he has the international version of the phone and is just confused.
