Which baseband/modem version would you recommend? - Galaxy S II Q&A, Help & Troubleshooting

Which modem/baseband version should I use for my Bell Samsung Galaxy S2 I9100M? I'm using the Bell network in Canada.
Right now, I'm using baseband version I9100MUGMA5 and the battery drains fast and there is frequent signal drop compared to when I was using baseband version I9100XXLS8 but I wasn't sure this baseband was using the right frequencies for Bell.
Thanks.

Try the modems bundled with stock roms released by your carrier first; reasoning being you'd hope they tested that the modem works for most people in most places with their network when they tested the rom before release. Then try modems bundled with roms released by other carriers in your country.

The I9100MUGMA5 baseband is the one that I had when I had the stock android from Bell for the Samsung Galaxy S2. I was just hoping that someone could tell me that another baseband is way better with the S2 for a better signal and battery saving.
Thanks MistahBungle for your reply.

According to Samfirmware, your carrier has released 5 stock roms total. You've tried one modem. So, using simple arithmetic, you have another 4 you can try.
Or you can sit here waiting for a reply that may never come (which will probably tell you the exact same thing I just did). Either you want to fix your connectivity, or you don't.
I've given you the fishing rod, a bucket of bait & detailed instructions on where to fish, you need to do the rest.

Thanks for the straight answer. I was just hoping someone would have went through this exercise before me but I guess not. I'll try all the modem drivers and see which one is better. I'll return with my findings.

[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.

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.

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.

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.

Calling all Canadians! Bell Telus and Rogers users.

Alright so ill start this of by saying, Picked up my note today and loving it so far. Got it rooted thanks to Da G and getting ready to get into roms.
Anyway im making this thread to see if anyone else has tried anything out on the non-AT&T notes(i.e I717M and what not). So far from what i have read people are developing mostly for the AT&T model and saying its not for bell rogers or telus. Now I have been in the samsung world for a while and when it comes to my galaxy there was always ways around this.
For instance most of my ROMs were made for the international version not my bell version. But as long as I kept a copy of the bell modem on my phone i could just flash that and the ROM worked great. So does anyone have a copy of the bell telus or rogers modem for the note? or know if there all the same?
Another example in the galaxy s world was the captivate(Same soft keys as our phones). A person with a captivate could flash an international ROM as long they made a soft key fix when they developed the ROM.
One of the main reasons I ask all of this is because i see so many N7000 ROMs up and running and am wondering what will and wont work.
Look forward to hearing from you all

The N7000 ROMs can hard brick your phone since the hardware if the two models are completely different. AS Far as ROMs go, most are based off the AT&T software simply because that's the only ICS leak we have available. But you can use any ROM for the i717 on your Bell Note. I have a Bell Note and flashed almost every ROM and never ran into any problems. Also, Ruth the help ofa lot of people on this sure, I've made stock images of the Bell, Telus, and Rogers Notes so we can always go back. Best if luck and don't hesitate to ask anything.
Thanks for the info, I get mine today and was wondering the same thing.
Yesterday I flashed my Rogers Branded Galaxy i717 with Bell Rom and Kernel and have not 1 issue. I chose to flash the rogers i717 with Bell because I use bell mobiletv and this was the only way to get this particular app to work. Again not 1 issue with data or anything else.
No Rooted device either. Just flashed using ODIN.
I'm currently running the UCLE2 Rom on my Rogers i717. I've noticed that I am not getting LTE where I should be. And GPS connectivity is shoddy at best.
I have a second i717 which is stock that is with me to compare (family member).
I am going to flash the Rogers modem to hopefully correct atleast the LTE issue. Anyone know if this would improve my GPS connectivity as well?
For a number of years I have been buying Canadian phones to use on ATT. Canadain ROMs have less restrictions than ATT. For instance tethering and NFC are not locked. Also after rooting my Roger's Note it took under a minute to remove the Rogers branding. (all except splash screen) I was left with a fully optioned unbranded ROM.
I did want to try the stock UCLE2 ROM out of curiosity but I thought it would not install because my phone was not an ATT I717. How did you install it eugenekim618? Personally I would rather wait for the Rogers ICS version. Keep checking everyday to see if it is available.
I have tried quite of a few of the ROMS on here with my Bell i717M, no problems at all so far, other than the "android.phone has stopped working" at startup, I don't know the cause but it only happens at boot.
DO NOT use N7000 roms! But all of the AT&T stuff has worked great for me.

I followed the posts in the Dev section to Root the phone.
Then installed CWM.
The picked a ROM I thought was good and followed the instructions in it's respective post to install.
I've done a lot of ROM installs for the Dell Streak I used to have and for a Sony Xperia X10.
So I am not totally unfamiliar with the process. Just a matter of getting used to the delivery method for each manufacturer. And then, dealing with the quirks of a ROM that is not 100% for your carrier. Goes with the territory, right?
I tried to read all the posts in a given thread as much as I can.
So you are saying you didn't install the one click odin stock UCLE2 ROM?

No, that doesn't work for non AT&T phones I believe. I tried it, and ODIN recognized the COM, but failed to install. From my readings, can't do the one click install on Rogers since it's not a Rogers ROM.
all custom roms should work no problem, ive flashed tons on my unlocked bell note.
its the stock odin files when you want to make sure you get the proper device.
Hey guys Ive flashed pretty much all the roms I can and some I cant lol. So far my experiances have encountered a few setbacks but nothing substantial and allot if not most of the bugs and glitchs occurring in the first & second gen of roms have been fixed or patched.
As far as roms go as was already mentioned as long as you stay away from n7000 model roms and stick to i727 youll be ok. With at&t roms I always seem to have signal and gps issues. Generally tho I find my signal problem will clear itself up on its own and I believe is actually just just caused by the fresh software 'settling in', even though my signal appears low or fluctuating speed testing always shows Im getting peak d/l & u/l speeds. If the signal doesnt seem to improve flashing the Bell stock modem via cwm always does the trick. Gps usually works great, very fast & accurate, when Im having location issues I use the 'faster fix' app from the market, I dont know about anyone elses experiance but allot of the times theres a problem the gps server isnt set to the normal 'north america pool' but servers Ive never seen before or set to an 'international pool'.
All in all besides signal headaches the only other recurring problems are the inherent and unpredictable random force closing of system apps. It can be pretty random but I find a few constant trouble makers to be at&t software update, android phone. At&t update can be disabled easily under applications in the main settings or I was able to actually remove it using 'rom toolbox's app manager but strangely not with root toolboxs remove system apps. For pretty much all other f/c problems the remedy is a running of 'fix permissions', there are a bunch of ways/apps to do it and Ive found using 'rom manager' works the best meanwhile rebooting into recovery and fixing permissions from there will actually cause more problems.
Ok so those are the most recurring and annoying issues Ive had to name a few but the list is too big to write merely because Ive tried just about every rom right from the sketchiest unstable first releases and everything in between lol so feel free to drop me line if your stuck on a problem cause I might be able to help.
But before I end this novel here lol I just flashed the new 'OnlyOne Beta2' rom from the development section and it runs great. The rom is super stable, very fast and features both fully functional S Voice app and fully functional S Notes app. If you havnt tried S Notes yet its awesome the new functions and abilities totally blew me away so I highly recommend you give this rom a try!

If you had LTE before and lost it through flashing a custom ROM or whatever then try changing your APN to your Carrier LTE network. If you never had LTE when you bought your phone, probably the seller gave you a wrong sim. tell her to give you a 403 LTE capable sim, the 401 is only 4G.

Try *#2263#
Then force select LTE, and select ALL. That should force the LTE connection. So watch the connection bars. You should see a loss of connection, then reconnect on LTE. Once that is established, do the code again, and just select automatic.

When I try dialing it, it says error can't find USSP or something like that... What does this mean?
Just to be clear that im doing the right thing. I go to the dialer and punch the code *#2263#. How do I "force select LTE"? will something popup for me to select it or should I go to settings/ wireless and networks... I don't have those options in "wireless settings", I only have APN settings...

Canadian carriers different ICS baseband implications for custom roms...

Like many Canadians today, I was happy to finally receive my official update to ICS. Actually, I was happier the day before when I learned that Google had released source code for ICS on our phone. Like many, I had intended to jump into the custom rom scene after the marvelous Devs in these forums have had a chance to cook up roms in a fully stocked kitchen.
Should Canadians be concerned that the official baseband, modems, kernals for ICS bear different identifiers than the AT&T ones?
I have always been concerned that there doesn't seem to be a dedicated forum for Canadian carrier Galaxy Notes. Until now, I have bought into the idea that all North American Galaxy Notes are the same hardware. This diversion in modem naming has me concerned.
I would eventually like my Bell Mobility Note to have a rom that has all the S pen functionality of stock with some of the upgraded Voice features from the S3. Most importantly, I need it to work flawlessly with the LTE network in the Toronto area.
I had high hopes for team perfections rom but recent developments have me wondering if it's future development will be AT&T centric....
I'm on a rogers note in Vancouver and i've run many different roms with at&t modems fine. It comes down to your APN settings but i'm currently running the June 28th version and it's been very solid. I've tried 3 different at&t modems over the last month and had no issues with speed on LTE.

Thanks for the reply... Do you find that you have to set the APN settings each time you flash a new rom?
I'm sure it's too early for someone to have had a look yet, but is there a way for Devs to see what differences there are, if any, between the Canadian carrier modem and the US ones?
I too am concerned. My biggest issue is wanting to use bells mobiletv app. All custom roms do not allow the app to work properly. My apn settings are direct to bell. So for now i ride my newly loaded stock until something magical comes about!

Carrier tweaks are nice but usually there's a work around within a few days of a new rom.
Modem-shmodem it's an SGS modem not an at&t modem and it is interchangable with all galaxy-s phones with the same radio chip.
Well, I think we have a bigger problem with the changes made to the bootloader on the Canadian ICS update. It seems that getting root and CWM is proving more problematic for us than US users because the recovery module keeps being over written each time we boot..

[Q] Trying to find the right Modem (baseband) file?

Hello everyone,
So I'm not too good with the whole modem/baseband issue. What I'm trying to find out is which modem file works best with AT&T, and since AT&T sells a different version of the S2, I know I can't use the basebands for that model. Does anyone have a recommendation for a baseband that might work. I'm in Manhattan, KS, but I don't need anything tailored to my area in particular, just something that would work US-wide (I'm coming from the korean version of the S2, so my baseband is COMPLETELY different for some reason)..
Thanks a TON for the help, everyone!

You don't wanna get a branded ROM, you are looking for as stock as it gets ROM (super-hyper unbranded). Forget about AT&T, I really don't think basebands differ from one model to another.

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+ .
