No signal on any Jellybean ROM? T-Mobile US - HTC One X

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.

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?

Which WiFi options? Is the Rogers ROM disabling some WiFi options?

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.

How do you set 3G data only, dont want to use LTE to safe battery life.

In mobile networks switch network mode to wcdma only.
Edit: could be hspa only, depends on your model.
4g is not lte by the way. If youre on lte it says lte not 4g
Sent from my LT28at using xda premium
lte is 4g on most roms that I have seen. Although I never used the lt28at just the lt28i and lt28h where hsdpa+ is called h+ and lte is called 4g.
There should be a toggle that you can download that will be able to click 2g 3g or 4g. I know on miui there is a toggle for that.
If you're using a Lt28at like me, you can't toggle anything but LTE. SInce the boot loader is locked it will give you the option to pick a different frequency, but will automatically revert back to LTE. Sucks.
The version i have only give me LTE data, or no data at all.
It is locked to rogers.
Can it be changed so i can use 3G only?

No. Your boot loader is most likely locked also. You can only choose LTE. The only other option is to find the APN setting for 3G and enter it in your mobile networks and choose it. It will only use 3G but your phone will always search for LTE by default. You will save some battery by going that route. I don't know what the 3G apn for Rogers would be, however or if there is one. AT&T has a separate apn for LTE and 3G. Maybe someone else here knows more...
Yea, i just found out this can not be unlock... thinking android can be unlock easily since my last 2 phones can do it.
I will find the 3g apn.
Hopefully someone can find a way to unlock it and use other rom..

Phone stays on HSPA when LTE is available

So I own a D851, currently on T-Mobile with good LTE speeds in my area but quite often the phone switches to HSPA and doesn't utilize LTE coverage when I need it. I end up having to either switch data off/on or accessing the radio settings menu and setting it to LTE ONLY. I understand the slower network coverage saves battery but to just stay there I don't get when I'm getting download speeds of 9mb on HSPA and 30mb on LTE in the exact same spot. The thing that sucks about setting the radio to LTE ONLY is that I can't browse while on a call. Anyone know a workaround?

I had the same issue with ATT, unlocked phone. Made sure the APN was correct, tried may other APN settings, and finally called Consumer Cellular. They advised I did, indeed, have the correct APN (my first version). They did some type of reset on their end, and viola.
On my OnePlus it was the similar. APN was correct, same APN as the G3, but until I called CC, and their reset, phone would not show LTE at all, only H and H+
apn settings?

What are the apn settings that are working for you? I've tried several times to address this issue with CC but lte STILL isnt working on either of our 2 devices. Had no problems when used with an att account.
I am still having this same problem on my LG G3 (vs985) on Cricket Wireless

Cricket SIM in AT&T E980 data issue

Hi all,
Before I rooted and put a costum ROM on this E980, I would get LTE service on this phone with the cricket SIM, about 6-8 mbps, since I put the custom rom on, I dont have any data from the get go, but if I put the cricket APN settings in, I get H+ data but its less then 1 mbps... I need to figure out how to to get the LTE to work on this.
When i try to enter AT&Ts APN settings into the phone, and I hit save, to save the APN settings, it wont save it and everything disappears. I've tried this on 3 different ROMS..
any help would be appreciated.
Thank you
If it was that slow it wasn't LTE. For example when using my Sim in a vzw phone if I set to global it would say LTE but be slow as balls, not send texts. When set properly it said H+ and everything worked

AT&T Caps cricket customers to 8MBps on the LTE network, at&t customers get 40mbps or so. but I'm getting under 1mbps... has to be some sorta setting or APN issue. When it used to say LTE, i was getting close to the cap of 8mbps.
Then try flashing a radio. The ROM itself shouldnt mess with anything like that really
