[Q] ICS Modem for 850Mhz - Galaxy S II Q&A, Help & Troubleshooting

I'm using AOKP Resurrection Remix 2.5.3 with Fluxi Kernel and XXLPS Modem. Is this a good modem for 850Mhz? Is there a better one?

Yes, couse we have the international gs2 version all modem are for 850mhz bands so dont worry and use the one with the rom.

I'm going to jump on this one as well.
Is there a way (either in basic settings or editing a file) that I can force the phone to use the 850MHz band?
My carrier is shutting off the 2100MHz network in a shade over a month and I want to start seeing how bad my reception is going to be once this happens. And I'd rather have nothing than use the really awful 2G network they still run (even though I thought they'd shut that off several years ago to force users on to their LTE network).

Although in the wrong section (should be in q&a not general) I'm also interested. The best way I found is that to search for roms that are for your country and see what modem they use. For ex. I'm in Thailand and I found that my modem, DCKL1 works best for me.

INeri, thanks for your reply.
NZed, sorry I didn't know it should be in QA. I'll search in other roms, maybe I can get anotherone.

[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
Sent from my GT-I9100 using XDA App
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] Having reception problems with my i9100.

Hi there everyone.
I have a Samsung Galaxy SII. I live in Australia, have an unbranded phone, and am currently with TPG as my phone provider.
I have been experiencing these problems for a long time, and after trying to figure out what's wrong with it, it's time to ask for help. Haha.
These problems started after I flashed a new modem after installing a ROM. Previous to flashing, the reception had been fine. After flashing the ROM, and not the modem, my reception was still as good as it was when I first received the phone. However, after flashing a new modem, the reception dropped significally. Where my brother also with a i9100 could receive full bars of HSPA/3G, I could only receive 2/3 bars of G. Where he would have 3 bars of G (in our house, it has this stupid insulation that really nerfs reception), I would receive absolutely no reception.
I have tried countless modems (pretty much ever modem since K13, testing for reception, but never have much luck, maybe a 1 bar fluctuation up/down).
Do you have any ideas what could be wrong? How I could fix it? Thanks very much.
find the modem your brother have ,download it from the intratech and flash it
have you tried KE7?
I got a good expereance with this on Data speed, but I dont know about reception strenght.
go through discussions of this thread http://forum.xda-developers.com/showthread.php?t=1131950
He hasn't updated for a while, and is using the K13 modem. I have tried it, along with the K14, and KE7 already.
do a factory reset without the sim and sd card....
I tried factory resetting without the SD and Sim card, but it still didn't work.
Any other ideas? Haha.

3UK, 3 Ireland, Three Network CSC and modem Problems

I'm creating this thread for anyone running on a 3HG network. There seems to be problems with custom firmware not being able to differentiate between the 2G and 3G networks.
I'll explain. I'm currently using a custom ROM and very happy, however, the stock rom seems to have some built in special features to detect the 2g and 3g portion of the 3 network separately and ban roaming unto other networks. (For example, O2, vodefone etc say (not allowed) next to them when searching with stock rom.) I know 3 does not run their own 2g network and the 2G portion is "roaming" onto vodefone without charge. Even though the phone detects the 2G portion as "3", whenever you connect to it the phone goes into Roaming mode. However the stock rom default is to "Allow National Roaming" (An option not present in my custom rom) and the stock rom then bans other networks besides 3 so that you can't accumulate massive data charges.)
I assumed that this feature was built into the .csc portion of the stock ROM. However, this is not the case.
I was able to download the csc portion of my rom from androidfirmware.net.
Unfortunately, I did not solve me problem. I'm on 3 Ireland. My stock rom can breakdown the network information into two networks:
3 (3g)
3 (2g)
It then selects the best one based on signal.
Unfortunately, myl custom rom (omega 13.1) just see two networks named as:
3
3
It doesn't switch back to 3g ever. It's a shame, I thought flashing the csc and modem from stock rom would fix this but it doesn't. I might have to always run stock firmware.
On another note, for those interested in modem files, regardless of which 3 Network you are on, you MUST run either NELF1 or NELE modem on your rom. I have extensively tested all modems and 3UK/IE are setup to specifically work best with these two modems. The download speeds are very fast, but more importantly they are consistent. I was able to obtain better speeds with some other modems but it would stall and hang and drop. These speed bursts did not make it faster overall. My signal was about 1/3 of the 3uk modems with all other tested modems. If you flash any custom rom you will notice a vast improvement in battery life, signal and consistency using one of the above modems

I have not tested between the two, I tried the latest version NELF1 and was blown away by the difference so just kept it. Cheers!
Any help with the above network differentiation problem would be appreciated. Feel free to post your thoughts or comments or suggestions.
Thanks.
Its well known that the NE modem range are better and even better than stock for some on non 3 networks
First general release was. 3 Ireland
Firmware info: PDA: XXALE8 | Phone: NELE4 | CSC: 3IEALE3
UK 3
Firmware info: PDA: XXALE8 | Phone: NELE4 | CSC: H3GALE4
Same modem different CSC
jje
I run every sort of Rom on my phone and never have those problems.
Using XXDLH9 modem now and pulling 6mbps down and 2-3mbps up and I live in the country, haven't used NELE4 since the day I got the phone.
Also in regards to the roaming and the massive charges, you won't incur any charges when you roam in Ireland, it will use Vodafone and that's it, even then they only let you use 2g data too and that's not charged either.
You must get poor signal where you are seeing as it keeps dropping back to 2g, try going into settings > more settings > mobile networks > network mode and changing it to wcdma only wait a few minutes and see how you get on.
To add to that: as far as I know NELE4 and NELF1 won't work on new firmwares. Voice calls get messed up, you can't hear them or they can't hear you.

Hey lads,
Did anyone ever find a solution to this problem. I'm on three ireland. I've an old galaxy s young with always stays on H/H+ and never drops to egde no matter where you are where as my new S4 consistently drops to edge over H when coverage is low.. is there any solution to this problem? I've flashed on the three firmware from sammobile but it's no fix!
Eoghan.
I'd also like to find out if a solution was found for this? Does anyone know how to go about modifying modems or something along those lines that could solve the issue?

[Q] what modem do I use with CM 10.1 M3?

Hi,
I am using CM 10.1 M3. I haven't updated my modem in a long time. It is I717UCLF6. Is that the right one? How do I know which one to use?

It's kinda hard to answer which modem you need without some more details. It's also a personal preference based on where you live. Some modems/radios work better in certain areas than others. What network are you on, AT&T? I'm on AT&T and heard the latest modem for our i717 is the i717UCMB4. You can flash that one in recovery. I used it and it works but for some reason the i717UCLD3 modem is working better for me. I got that modem when I used odin to install this rom, then flashing my favorite rom on top of it. Some people say the UCLF6 modem works better for them. You can get that one here and flash thru your recovery. Sorry I can't find the i717UCLD3 flashable zip. Maybe someone else has a link so you can flash between all 3 and see what works out best for ya.
No need to do any modem flashing. LF6 is the latest and greatest modem available.
Updating.....AT&T released 4.1.2 and a new baseband/modem which can be found here http://forum.xda-developers.com/showthread.php?t=2261713 and is flashable from custom recovery.
I'm testing out a possible switch to T-Mobile. Had AT&T unlock my phone today and got a prepaid T-Mobile SIM in it. I'm getting H+ (LTE?) speeds while doing data transfer and then it drops back to 3G when data isn't being used heavily. I'm on UCLF6. Although I've had this phone for a year, installed tons of ROMs, compiled my own kernel, etc. I'm a noob when it comes to modems and have just used whatever worked. What's the advantage of using a "T-Mobile" modem if UCLF6 seems to be working on T-Mobile anyways? Do you get more speed out of it?
I don't want to lose AT&T compatibility yet as I just got the prepaid T-Mo to test out (been getting crappy reception with AT&T at work and tired of the expensive plan of minutes I don't use). If T-Mo improves my speeds at work I'll probably just pay to cancel my AT&T contract and transfer my number, but for now I'm just testing.
Well I am not sure about the baseband/modem issues on T-Mobile but most important would be the GSM Bands/LTE are compatible. As some AT&T phones don't support 3G/LTE frequencys T-Mobile use. If you are using a prepaid SIM it may not even support LTE for example Straight Talk on AT&T supposedly will only use HSPA+ .

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:
