[Q] Modem Help - AT&T Samsung Galaxy S II SGH-I777

I have a Samsung Galaxy SII, the i777. I have rooted it and loaded ShoStock3. I love the ROM except I'm having trouble downloading apps from Google Play. The research I have done suggests that I need a better modem. I have downloaded and flashed six different modems. Each one just as slow as the last. I'm in Salt Lake City, Utah. I know that the location can have something to do with the modem as well. Does anyone have a suggestion on which modem would work the best? Also, if you happen to know that there is a separate problem and that it's not the modem, will you please let me know? Everything else seems to load fine, it's just trying to load apps from the market that I'm really noticing it is really slow. Thank you everyone in advance.

Modems are good in different places. What's good for me might be awful for you. Have you done a speed test?

You've already flashed 6 different modems, you should know by now which one is the best for you out of those 6.
If you don't like them all, try some more and pick out the best.
Have you tried KH7 or LL6?
Side note: why can't you use Wifi for Google Play?

You are I assume flashing modems for this device right? I only ask because obviously the i9100 modems wouldn't work for us. (And I'm pretty sure calls don't work with them) also, if you are flashing all these modems and they ARE for our device, and NONE are working properly, I would look at a fresh flash of the rom of your choice wiping everything again or going back to stock to eliminate hardware error possibility.

I did verify that they were all for my model and network. None of the six were any better than any other. I also noticed none of them worked on the 4G network. I tried to download an app to do a speed test but after 30ish minutes waiting for it to download on each modem so I could test it, I gave up.

Shoman94 changed to UCLL6 modem on his latest build. Are you using this one now?
Or you can select all the modems from here:
http://forum.xda-developers.com/showthread.php?t=1336958
They seem to be working OK, at least for me. I have tried at least half of them although I am still running ICS (CM9.1), not JB like you.

In the Settings of ur phone, since u r runnin SHOstock 3, do u have the Mobile data box checked under Data usage ? And do u have the "Set mobile data limit" box checked under Data usage (this could hinder u) ?? And under More settings/Mobile networks is the Network mode set to something Other than the "GSM/WCDMA (Auto mode)" (this could also be the problem)??

So, I un-rooted my phone but from what I understand, even doing that won't re-set my modem. It's still working slowly. My biggest fault here was not doing speed tests from the beginning and not noting down what my phone came with. If I could find what modem my phone came with, I would root and load it back on.
I really appreciate everyone's help and suggestions.
Is there anyone in Utah on the 4G version of the SII that could tell me what their modem is?

Check your APN settings, that can cause plenty of issus for data.

[Q] Data Issue with Phonebreaker 2.1 Rom

Hi Guys,
I recently got the SG2 on AT&T (i777) and the first day I had it stock I was getting consistent H+ connection in my house and pretty much everywhere I was going. I ran the speedtest app a couple times, and I was averaging 2.5-4 mbps downloading which wasn't too bad.
That same night I rooted the phone and flashed Phonebreaker 2.1 rom following the correct steps (Not my first time rooting/flashing roms, I've done it to my Tmobile SG2 a few times). However the following day it seems my data connection has become inconsistent and speeds have slowed down to a drag. The indicator on the phone can never stay on H+ or even H..it consistently cycles from H+ to 3G to H (tried it in same locations as the first day with the phone). I ran the speedtest a few times and my download speeds ranged from 300Kbps to 1.6mbps if I was lucky.
I tried looking around in all the forums, I re-did the APN settings found in these forums, I troubleshooted with AT&T but to no avail.
Anyone have any suggestions? Would much appreciate it as I love this ROM minus this data issue I'm having.
FYI - Stock only shows H+ even if your not actually on it.
Its an illusion AT&T does to make the user think they have great connection everywhere.
Also try flashing a different modem, that might be the issue with your speeds, cause I changed to the leak's modem upon many request.
Thanks LiLChris06!
I tried the KH7 modem which did nothing, and I tried the KK6 which seemed to improve it a bit. I went into AT&T today and they said maybe it's just a defective phone and were willing to switch it out, which I might do.
However I love this ROM so much, is it available without the custom modem you added or with a different modem in the install rather then the UCLK2 I think you included?
Thanks

Hmmmm...what you mean by is it available without the custom modem? Maybe Im reading it wrong. As you know, because you said you have tried different modems, there are many different modems you can try. Shouldn't matter what modem the ROM comes with. Think there is a modem thread around here that has some good info. I think Task also just uploaded the the new LC5 Modem
I should have worded my reply a little better, and it might come across as a newbie question but basically I was wondering if that rom came with the stock modem the i777 comes with because when I had the phone the first day stock, the data speeds were pretty reasonable (3-4 mbps/downloading).
Wasn't sure if flashing different modems other then the one that came with the phone originally would help out my issue, but I suppose it doesn't hurt to try. I did find the UCLC5 modem so I'll try that in a few minutes along with the other ones I haven't tried. If no luck, I'm going back to AT&T to exchange, probably defective phone like they said.
Thanks again for everyone's help
Sweet, found a solution!
I tried all 7 different modems under the same conditions, KJ1, KJ4 and KK6 were around the same ball park. KH7 and UCLC5 were a bit slower but close to each other, UCLC2 was by far the worst..and the winner was KJ2, big difference.
Thanks guys!

Problems since BLG8?

So last night I updated my s3 to the latest UK firmware, XXBLG8, And I can't tell if my problems stem from the latest update!
After the update many apps wouldn't open and I'd have to do a battery pull to sort out each individual app that refused to load, everything's fine now, however, my data connectivity seems to have worsened considerably, even with full signal strength and HSPDA nothing will load, the browser shows errors that I'm not connected to the internet and apps such as the Play Store and Speedtest won't connect.
Anyone else experiencing this problem? Would I be able to flash back to an earlier firmware using ODIN? (I'm new to the s3 scene, just jumped ship from a Desire HD and haven't yet fully got my bearings.)
Thanks guys!

only problem i have noticed is that speedtest does no longer work but everything else perfect. Infact my hsdpa connection is much better on this rom. you can easily downgrade your rom back if you wish just follow this excellent guide to flash via odin.

Hmm, I suppose it could be the area I'm in, but it's usually fine where I am. I'll give it another couple of days and test it in other areas to see if the problem persists.
I've upgraded via ODIN before, just wasn't sure if there were restrictions on downgrading etc, I'll give the thread you linked to a good read now, thanks!
Try changing Modem BULF1 for starters .
I find the last two updates modems are very poor .

I am also on the 8 firmware and so far it's good.
looks like speedtest.net have changed there site slightly if you goto site with mobile agent set on browser it redirects to the play store to the speedtest app, change browser to desktop as long as you have flash installed all is fine. I believe this has been done site to the up and coming removal of mobile flash

Thanks, I'll give it a go!
So I decided to bust out my Desire HD, I remembered I still have a month left on my old contract before it gets terminated, checked the data connectivity on there and I seem to be having the same issues. Looks like it's a problem with 3 in general rather than it being my s3. Which is good news for my s3!
Must have been pure coincidence that I started having these issues right after upgrading, however, I tried a few new modems and have been getting better signal (no change with the data issues) so at least I've taken something away from the experience
Isn't there an issue with 3 UK branded ROMs experiencing network issues when you flash the unbranded ROM? I think you may need to flash a separate modem, Google it, I may be wrong.
I'm on 3uk running blg8 not had any problems making, receiving calls and texts and my network is fine on both wireless and 3g

It seems to be working pretty well this morning on both my s3 and DHD, and Frostfree I'll have to check that out, I've already flashed a few new modems and I'm getting better performance so that might very well be the case!
I'm in Folkestone (south east coast)
I am on BLG6 with Cyanogen Mod 10 latest rom and so far I have great speeds (4-5Mb) on speed test app.
Will try flashing BLG8 when i can find a download link. I just want the modem to flash not a whole rom cos i am loving JB on the SGS3.

Radio Needed For Cyanogen And Samsung Galaxy S2?

Hello, I've flashed the Cyanogen mod for my Samsung Galaxy S2? I've been using it, it works fine.
I'm wondering, do I need to flash a radio? If so, which one? I've seen the links of radios from the Wiki page of Cyanogen under Support Downloads, just don't known which one to use or if I'm supposed to.
Thanks for your help.
Radio is not changed by CyanogenMod.
If you have no call, sms or data issues then i dont think you need to change

OK, thanks for your help.
I have successfully installed this rom. I think it's the most amazing jelly bean rom for galaxy s2 at the moment. I like its smoothing and quick response. feel a bit warm at the back and the battery is losing 1% at every minute while wifi is on. Over all is great. Cheers!
Actually, I've been experiencing data connection problems. My phone works, but it won't connect to 2g/3g for internet.
Should I try switching radios?
If so, which one is recommended? Or do you just try them at random?
Thanks again
On first boot normally can't get mobile data to work because APN was not configured properly (or the list empty), after a reboot mobile data will work again. If it doesn't, then you have to key in the APN manually.
For radio/modem, since there are no changelog released and nobody know what are the differences among them, it is assumed that the latest one will be better.

first and foremost asking or recomending which ROM/KERNEL/MODEM ,is against XDA rules, since all phones are different due to various reasons , hence if u have a an issue with ur modem u have to try a cpl of them on ur own and see the one suits u the best.

OK. I'll try a few different radios. I see a list of links in the Cyanogen Wiki page of under Support Downloads.

It sounds like your apn settings are messed up. Try to reboot twice and then try. If that doesn't work, you will have to find the settings and input them manually.

I flashed this radio:

Now, the data, 3G, works great.
I've been experiencing an issue and have read several post about RADIOS on the SGS2.
I flashed my mobile with the nightly 10.2 CM and after that it started to ask me for "SIM network UNLOCK" Which I can't unlocked, thought it was the version issue so I dl a the newest one and same issue, I tried the ICS stable 9.1 and same issue.
I've read something like radios on the CM support part. Which I dunno where is it yet . If I need to flash it and u guys can help me out to pick up the correct one I'll appreciate it. my model of SGS2 is the i777 from AT&T.
May I install NELP on my CM 9.1? how? where can I get the files to do it?

What phone do you have? This is the thread for the i777 S2 variant, and at least one of the modems you mentioned are for the i9100 variant (don't recognize the others you list).
You can only use modems designed for your device, so if you have an i777 see the link directly above your post.

[Q] Modem/Connectivity issue

Hello people,
For the past few months I'm having this issue which I find extremely [email protected]!!
Every few minutes, my phones just loses internet connectivity - the 3g signal appears to be normal during all the time, thing is, whenever I try to use any internet application - it just hangs. and then, after a minute or so, connectivity is back(again, for a few minutes).
I have tried flashing so many versions of modems - some improved it a little but most of them didn't help at all, or even made it worse.
Hopefully someone could help me with that as I'm that close to give up on this and buy a new phone.
Thanks in advanced.
Nir.
Which firmware are you running on your phone? What modem do you have right now and where do you live? Do you have problems with all apps that use internet-connection? Do the problems dissapear when you use wifi?

Yop.. forgot to mention a 'few' things...
Model: GT-I9100
Rom: RootBox V3.8
Kernel: 3.0.31-CM-g7ce58e6
Baseband: I9100DXLPB
Android version: 4.2.2
I live in Israel, bought the phone in Thailand.
I tried flashing all available Israeli modems(from various cell phone providers) - none helped.
Problem disappear when I move to WiFi - as 3g connectivity moves to background...
Thanks.
I assume you've read the Rootbox threads to see if other people experience signalproblems?
Did you compare the connectivity with other roms? Stock-based roms for example...

That seems quite weird.. The only thing I can come up with is 1) a hardware problem, or 2) you live in an area where the signal is crap
Hopefully someone else knows anything.. Good luck.

If you've only tried flashing the modems bundled with stock roms from Israeli carriers, you haven't done nearly enough. There are literally dozens of modems available, you need to start flashing as many as you need to. This isn't going to fix itself magically.

I haven't flashed only Israeli modems but others as well. I've tried around 20 so far...
Question is, which direction should I choose? should I look for Thai modems or IL?
That depends. I know Israeli carriers sold (still sell ?) the I9100T, are you sure you don't have one of these ? If that's the case, I'd be trying modems bundled with roms released by the Australian & NZ carriers which sold the I9100T (I have one), and yes, the Thai ones as well.
If you do have an I9100, then keep trying any/every modem you can get your hands on. If it's not a carrier-side issue, this is really all you can try, unless you want to start messing around with RIL's as well. I've not found any difference in connectivity doing this personally (tho many people have) but if you get to the point of trying every single modem & you're sure it isn't a carrier issue, you might as well try. But I would leave this till last given many people find their connectivity messed up even worse by flashing an incompatible RIL.

[Q] Can I change modem im my AT&T Note?

HI everyone... I have a question:
I have an at&t sgh i717 with a virgin sim (Im outside of the us), and I need to choose a new modem (I think) because currently I have this t989 uvle1 for tmobile that I had to use to unlock my phone. I'm getting three bars in the signal so my question is or are: do I really need to change the modem? Does the signal have to show more bars so that one can be sure that the modem fits the phone? And, a modem has to be chosen depending on your phone and on your location (since I'm in southamerica)? does having a 2.6.3 kernel affect any of this, should I upgrade it?
I hope I'm not asking too much, sorry,
thanks

Edit - You mean i777, right ? (I717 is the AT&T Note).

Since you have an i717, normally you would probably want to flash back to an AT&T based modem. However, since you're probably not on AT&T's network, your best bet is to try several modems and see which one works best with the provider in your area. My recommendation is to at least base your tests on signal strength and speed tests.

OK, I'm going to try several because just yesterday I found out that my gps didn't work and I think that's related to not having a suitable modem.
Additionally, I performed a speed test and whereas I get 12 mbps for download in my laptop I got 10 mbps in my phone, not much of a deal though.
Regarding signal, I get from three to four bars which isn't that bad and I've made a couple of calls and everything seems to be fine.
Since the gps thing is a real setback I'll flash another modem but I'm also thinking on upgrading to ics because right know I'm on gingerbread 2.3.6 with 2.6.3 kernel so I wanted to know if It's better to flash the modem before or after upgrading.
Thank you for your answers
You will probably have better luck if you upgrade to an ICS or jelly bean based rom.

The gps not working isn't always antenna issues. You can try to update the gps data file. Go to the market and get a gps fix app. You're looking for an app that will replace your gps configuration file with an updated file.

Thanks, good to know that.. it's just that when I received the phone it was working and based on that and some comments on internet I attributed this error to the switch in modem/baseband/radio...
Anyways, I'm installing a rooted ics rom and I'll come back to comment, hopefully positive things
