Possible Switch to GSM ONLY on ([ROM] ICS Megamix 4.0.3 [4/10/12]) - T-Mobile Samsung Galaxy S II SGH-T989

The service in my house is pretty crappy and for the most part i use the Edge network. I my phone on stock does get a 4G signal, but it doesnt work. This ROM doesnt have the option to switch between WCDMA and EDGE....is there a fix to the or app or anything?

Use Llama to turn off 4g based on a location profile.

current ics u guys have was derived from us, the skyrocket community, which is based off an AT&T leak. AT&T disabled network switching in the elm framework, so there is no way to currently do this. Once we get an ics official drop (or leak ) from either Rogers or T-Mobile, the devs will cook up a solution

ROM difference between i927 & i927R and 4G symbol

Hi,
Being in Australia the Captivate Glide is not available locally so ordered it online via a parallel importer.
I was supposed to receive the AT&T version but due to no stock I received the Rogers i927R version.
I cannot root the device as my work place prevents it since I need to use it for work related messaging.
1. Is there a list of differences between the AT&T and Rogers ROM's ?
2. I'm on Optus which uses 900/2100MHz, so the phone will connect on 2100.
Using an App called Network Signal Info I can see data connection switching when I'm moving around as normal, but the data symbol in the notification bar doesn't match when on 3G as follows:
NetInfo | Speed | Notif-Bar-Symbol
GPRS | 55kbit | G
UMTS (3G) | 384kbit | 4G <-- doesnt say 3G
HSDPA | 7.2Mbit | 4G
This a bug or ROM incompatibility ?
Thanks.
The only differences I know of is that the Rogers ROM is carrier-iq free and the tethering option is unlocked.
In my AT&T version, I can't find any way to manually toggle between 2G and 3G networks. However the network info apps/widget show it's automatically switching between EDGE, HSDPA and HSPA.

It would be handy to sometimes by able to force 2G to save battery.
Anyway, can the Rogers ROM be flashed onto the AT&T Glide and still work ?

Good point.
Sounds like I should stick with the Rogers one they sent me rather than swap it for an AT&T version since the Rogers one will be most compatible without having to 'root'.
Carriers in Australia seem to allow tethering by default as long as you have a working App for it.
Thanks.
Which parallel importer did you use, do they have an online storefront?
Hope the Rogers version pricing comes down as fast the AT&T one. That's I went for At&T, down the line I'll end up flashing it with an open ROM. Mostly because of OpenVPN support.

Indeed that's why I asked, since I don't use any data packages.
I checked my mom's S II, appears to be an AT&T carrier limitation. It won't even scan for other networks. I set her S II to 2G.
Earlier I wasn't concerned with the AT&T ROM, but this one is annoying, I could save some serious battery time by switching to 2G.

They've been very helpful and responsive, trying to get stock as quickly as possible.
When they couldnt get the AT&T Captivate Glide they sent me the Rogers Galaxy S Glide.
Seems that was the better way to go.
AT&T locks down their network and band select while Rogers does not. AT&T uses an "H+" on the HSDPA network to show status while Rogers uses a "4G".
Learned by flashing Rogers ROM onto an ATT cglide. Changed the model to 927R as well. Went back to ATT when I noticed the loss of the ATT wifi options.

So even after rooting the phone, there's no way to manually change bands while on the AT&T ROM?

I'm using the Rogers version in Australia.
I have all the normal WiFi options and have used it at home and on public ones with no issues.
I think, just guessing, that Tynar is talking about the customized WiFi options on the AT&T ROM I have read about which gives you access to their own WiFi network.

Yep, I since had a look at the User Guides, of which there is a different one for each version Rogers and AT&T. The ROM's have been customized to show different symbols for mobile connectivity.

Ya... Thats at&t limitation, I guess... But atleast in my sister's AT&T Thrill phone (running Froyo + rooted with SuperOneClick) the "NETWORK" app (LINK) from AM/PlayStore works and helps in selecting 2G only or 3G only whenever needed...
But even that app is NOT working on my rooted CapGlide... May be because this phone has only rooted-ROM and not rooted-Kernal (as told by rooting guide in cap.glide development section)... Experienced members please help... I badly need 2G only for battery backup and 3G only for good speed as 3G coverage in my place is not great...
Thanks...

With AT&T Rom, you don't have that option.
You can flash Rogers Room (Untouched or Custom Rom) where you have the option of manually choosing network and choosing 2G/3G
Switching to 2G would really save on battery life.
So the notable differences are...
1. The AT&T ROM doesn't allow band switching or manual carrier search and selection. While the Rogers ROM does not have this restriction?
2. AT&T allows WiFi tethering, while Rogers doesn't?
3. Both versions come with Mail for Exchange apps?
4. Skype, G+ Hangouts, Google Talk, Voice and video works on both?
Please add/correct any other big differences. I'll make a table and put it up on Wikipedia once we have the notable differences, that could cause issues with international use.

[Q] Flashed Kj3 Telus Radio on new Bullet rom gets no serverice help?

I've been trying to flash an at&t radio for better signal to where i'm at .. everytime i do on any rom always no service.. then when i go to mobile networks keeps telling me i need to insert SIM Card.. Rom im using now is the KangKong Bullet rom since it is a Skyrocket rom thought i could flash KJ3 and get great service.. I was wrong need help!!! plzz!
I believe that you will need a radio with ICS RILs or a radio without the RILs to get it to work on an ICS based ROM

Nice try but, I don't think it works like that. I could be wrong here but, that would be what they call "roaming". It makes sense if you think about it. Why would AT&T allow you to use their towers and provide service when you don't have an account with them and pay them? And, when you do go into roaming, there are back-end agreements between providers to facilitate that. That's why roaming charges would be so high since a portion of that is paid to the provider allowing you to on their network to access Tmo network.
please feel free to add / correct my message here.

No signal on any Jellybean ROM? T-Mobile US

Whenever I switch to a Jellybean ROM, no matter which ROM it is, I cant get a signal, even if it is listed as working in the original post. Usually I just cant get data or MMS on Sense 4/4.1 ROMs, but with JB I dont get any. Does anyone know whats wrong?
Make sure you have the correct APN settings for T-Mobile.
BTW doesn’t T-Mobile use 1700/2100 AWS band for 3G data? One X doesn’t support 1700Mhz, so I don’t think you can get 3G on it, only the older terribly slow 2G data service.

Straight talk galaxy s3 Verizon version

I have the straight talk galaxy s3 that runs on Verizon towers...I have my contract 4G sim in the phone running a Verizon rom and everything does work but it roams everywhere I go and I don't get any 4G (disabled by straight talk). I was wondering if flashing a sprint rom would help at all? I seen the sticky saying not to flashing any rom from another carrier but I've flashed dozens of different roms and all has been good except the roaming. Anyways, just wanted to see if I could get some help here. Thanks in advance
What would it take to enable the 4G on this phone?

You might have to configure your APNs, or, if you haven't for a long time, you might need to update your modem, since you don't get that sort of update with custom ROMs. On my Virgin Mobile phone, I have to flash an APN fix on every new ROM, otherwise I just have 3G.

The straight talk version I have runs off Verizon towers and they have 4G disabled but the phone is suppose to be 4G enabled. The apn fixes didn't help. I'm wondering if this would need something like cdma workshop.
Ah, I see. Yeah, if the 4g is blocked on multiple ROMs, you'll need an app to fiddle with the sim card. Hopefully it's not hard blocked (a physical switch or the card is incapable of it even though the phone is)! I'd try to contact Straight Talk and/or see if it works on stock. If you're trying to get 4g without straight talk knowing, well, I don't know much about that, but CDMA workshop or something similar might be worth a shot.
I was thinking cdma workshop would be the answer but I don't know where they have it turned off. It sucks being confined to 3G when the phone is 4G compatible and straight talk will allow 4G on there Verizon network now.

[DOMESTIC][UNLOCK] Domestic GSM confirmed working on some AOSP roms

I can confirm that you no longer need to use the much outdated CM11 T-Mobile ROM, T-Mobile Stock ROM or the RayGlobe Flex ROM in order to use a USA domestic sim such as T-Mobile. I noticed that the BUILD.PROP on the T-Mobile CM11 ROM has some enabled goodies which do not come on the default CM11 for the LS980. That made me wonder what if I use a unified ROM (built for all variants) instead of the ROMs available on the Sprint G2 section? The build.prop there will still include capabilities for GSM devices, which CyanogenMod seems to strip in order to avoid switching to GSM (correct me if I am wrong). Anyways I gave it a go using the LS980 Bliss Pop ROM based on 5.1, which is found in the non-carrier specific section of the G2 Android Development, and sure enough I was back to being a Sprint device. Using the dialer, I accessed the Testing menu by dialing *#*#4636#*#*, switched to WCDMA preferred, and it seemed to have revert. Then I clicked WCDMA only and it stuck and I could see my signal bars changing. THEN I switched it to GSM/LTE and FINALLY HSPA+ appeared. Calls, texts, data, it all works as the APNs were already auto selected. MMS DOES NOT WORK. I've been using it like this for the past couple of hours and no issued so far. I cannot remember if I did the official unlock available on our section of XDA as I've had quite a few of the Sprint version on and off, but I really do not see what role that plays in the matter. If it doesn't work for you, then you probably do need to use the official unlock.
***Again, if my theory is correct, this should work only on unified ROMs, which are ROMs compiled for all/multiple variants.
It never worked for me on stock CyanogenMod ROMs for the LS980, thus my theory. Another theory I have is that since Sprint now allows domestic unlocks, these phones may be free to enter the domestic side if you can get them to recognize a domestic sim...
If you want pictures/proof, ask, its about 5am in my time zone and I'm too lazy to take them and upload them.
If you want to force HSPA+ instead of HSPA, use the "HSPA+ Tweaker" app found in the Play Store.
If you feel like this is good news since you use this device on a carrier other than Sprint, remember to thank me.
If you are in another country and are willing to experiment, try it and I'll update my OP as soon as I can.
If you have already mentioned this in another thread, this is my own thread, started so that others can see it easier rather than having to accidentally stumble across yours in another thread.
EDIT: Can confirm it works on other AOSP ROMs. When switching network modes, you must have a stable data connection or else it will automatically try to connect to Sprint towers.
MMS DOES NOT WORK!
Outside the usa GSM sims works perfect on every not SPRINT rom (stock based like cloudy or optimus, or AOSP/CM based)

Thus the first word in the title of this thread is "Domestic". Back then, you couldn't get a USA sim working with those AOSP based ROM, heck you couldn't even use it if the rom wasnt modified to spoof the T-Mobile version, see for yourself the domestic "unlocked" roms I mentioned above show your device as a D801. There has always been the international unlock which can be used even on stock, but that wouldn't help USA users.
