Rogers One X on AT&T - LTE Trouble - AT&T, Rogers HTC One X, Telstra One XL

I ordered an unlocked Rogers HTC One X to use on at&t, which I received yesterday (Wednesday). When I got the device, I inserted my SIM card, added the "at&t pta" APN (which I found here on XDA) and connected just fine to at&t's LTE network. No troubles through the rest of the day.
This morning (Thursday), I noticed I only had "4G" signal, i.e. not connected to LTE. I checked in the mobile data settings, under Network Mode, and saw that the GSM/WCDMA auto was checked. I switched that over to the GSM/WCDMA/LTE auto, LTE showed up in the status bar, but I had zero data connection. This has been the case all day today. The LTE symbol is there, but only the Up arrow blinks between white and black; the Down arrow does not light up at all, so no data on LTE.
- HSPA data works fine
- my at&t plan is definitely provisioned for LTE (I've been using a couple of other LTE devices in the last few months with no trouble)
- LTE data definitely worked yesterday (speedtest showed over 15mbps down and 11 up)
- I did put my SIM card back into my Galaxy Nexus for a couple of hours last night before putting it back into the One X (I'm thinking this is somehow related, but can't figure out)
- I've tried a couple other at&t APN settings (Cingular wap - fine for 3G data, but no LTE, 'Phone', again fine for 3G data, no LTE)
- My SIM card is indeed a micro-SIM and is only a couple of months old, at most
Any ideas? I'm pretty much out of ways to troubleshoot at this point, so any help would be much appreciated. Thanks!

I think there is a specific AT&T APN that you need to plug in to get LTE enabled. Did you make sure your SIM is LTE compatible? Are you running the stock Rogers ROM or did you install a custom ROM? Is your bootloader unlocked? Have you tried updating the radio to AT&T default radio?
Just wanted to knock some of those questions out there.

I think the AT&T PTA APN is the LTE setting that's out there. I haven't come across any others.
I'm completely stock (it is a Rogers rom), haven't yet rooted or unlocked the bootloader or anything like that. Nothing has been flashed.
Actually, I just realized I ran the software update last night before bed, which put me on software version 1.94.631.3. Android version 4.0.3, Sense 4.0. Now I'm willing to bet this is the cause of my trouble. But HSPA working and LTE not working is still puzzling.

I wonder if it's the radio version not being 100% compatible. Are you willing to unlocking and flashing a custom Rom based on an at&t Rom? That could rule out a software issue assuming your apn settings are good.
I have the Telus version and had lte issues until just recently on CleanROM.

I was thinking about going through the unlocking/flashing process this weekend actually, as I'm pretty sure there is an issue with the radio like you said.
Just need to find some good tutorials to get me started.
Thanks!

Check out the guide I have in my signature. It's for the Telus variant, but the Spoof-CID would work with the Rogers version as well. Also, the Rogers version is, by default, unlockable though HTCDev.com so you're good there. The step by step instructions on HTCDev is pretty straightforward, but having a tool like the Spoof-CID program helps in getting the required information sooner.
Definitely read up on it and ask as many questions as possible. Good luck!

Great, I'll check out your link.
Thanks for the help.

So I managed to get LTE working!
I figured I would at least flash a different radio.
- Started out with the htcdev.com unlock method, which was pretty much painless.
- Used the method in Athrun88's signature to get TWRP flashed over to the One X
- Downloaded (and flashed) one of the CM10 nightlies
- Downloaded (and flashed) the AT&T 1.85 radio file
- Dialed *#*#INFO#*#* from the deviced and selected GSM/WCDMA/LTE auto network mode
- Got LTE!
Flashing CM10 might not have been completely necessary of course, but I couldn't resist, and it's been pretty great so far.

Make sure you go and knock out the superCID hack too. That way when things go wrong, u can use the 1.85 at&t ruu and skip all that in the future:beer:

Hi SBA1226
Thanks for sharing. I had the same problem after doing the Rogers update and thought the At&t LTE service was out in my area.
I had flashing experience with my gnex, but never dealt with HTC phone. What exactly is that Spoof-CID.bat procedure as described in Athrun88's guide? Was that the guide that you follow? Would really appreciate if someone can point me to a step-by-step (maybe with picture ) guide.
Another question I have is do you loose functionality like wifi hotspot or media link HD when you flash custom rom like CM10 or cleanrom 4.5 DE?
Thanks.

I did not use the spoof-CID in Athrun88's guide, but I did use the rest of the guide to get TWRP recovery flashed to my One X.
You'll want to start out by going to the htcdev.com site, registering, and following the step by step instructions there to get your bootloader unlocked. They make it really easy to complete.
Once this is done, you should still be in fast boot mode, so just follow Athrun88's guide to flash TWRP, and you're on your way to flashing ROMs.
I can't speak for CleanROM, but I've had no issues with wifi tethering in CM10.
Also, there are quite a few guides on YouTube that I found really helpful.
Good luck!

Thanks. I will try it this weekend.
By the way, is there a simple way to back to stock? Thanks.

I was in the same situation with a Rogers One XL, no LTE on CM10, and here's what I have done so far to get LTE working, though I'm not quite done.
1. RUU back to 1.94 Rogers (from this thread): http://forums.team-nocturnal.com/sho...X-XL-LTE-RUU-s
2. Unlocked the bootloader using the official process, flashed TWRP
3. Flashed the stock rooted 1.85 ATT ROM from: http://forum.xda-developers.com/showthread.php?t=1671237
4. Flashed the ATT 1.85 firmware: http://forum.xda-developers.com/showthread.php?t=1694012
I had LTE now.I then flashed to ATT 2.20 ROM & FW (not RUU) and LTE still worked.
I assume it was a RIL/FW compatibility/requirement for ATT LTE, so going to CM10 should work, but I have not tried.
Hope that helps some.

[Q] Question about Root/Rom SR

So I am looking to get a smartphone. Never really had one, and I am looking to get an android phone. In the end, I think from what I have researched, to get a SR, on the TMobile prepaid network (I am not a fan of contracts and paying too much for what I need. I would mainly need data, and the TMo prepaid seems to work out the best). So I want to make sure I got all the steps covered.
So from what I gathered, in order to get a SR on TMo, I will have to root it, unlock it, then install a TMo radio to get TMo's 3/4g network.
So the steps I need to take are:
Make a backup of the stock phone (or find the Stock Rom) just in case anything goes wrong? I think this is called Nandroid backup? I am not sure how to make a backup myself though? I believe I can just Clockwork Recovery?
Root the phone (is the root permament? Or do I need to do it everytime I restore the backup/stock ROM?)
Install Custom ROM (I am probably going to either install CyanogenMod or Sky ICS).
I found instructions on CM here: http://wiki[.]cyanogenmod[.]com/wiki/Samsung_Galaxy_S_II_(AT%26T):_Full_Update_Guide
For Sky ICS, I was going to use: http://www[.]traemcneely[.]com/2011/12/27/install-custom-rom-at-ciq-removed-short-review-instructions/
Unlock phone. Is this temporary? Do I need to get a new unlock code everytime I change ROMs, etc?
Install Modem ... I do not quite understand how to do this. I found a list of radios that is supposed to work in the i727: http://forum.xda-developers.com/showthread.php?t=1426001 I think I get the SR Series Rogers KJ7 modem. But I am not sure how to flash the radio only?
Am I missing any steps? I want to be sure I got everything I need to do this. I haven't bought the phone yet, but I am researching everything before I get the phone.
Alot of the information I got from: http://forum.xda-developers.com/showthread.php?t=1383464 I was going to Root it by zergRush.
Also, I was wondering if I should wait for the new SoC chip from Samsung to be released? I read that the Exynos 4212 will be released in new phones soon (rumored to be in the SGS2+ in next week's Mobile World Congress) and that the new Exynos chip will support LTE? Where as now, the SGS2 SR LTE is the qualcomm chip.
And the reason I was thinking LTE was that if I didn't like TMo and its 3g/4g network, I could then try out AT&T and their LTE network. I am in LV where they have the LTE and TMo's 4g network.
But anyways, if I am missing a step or doing it in the wrong order, any help would be appreciated!
Wow, I'm impressed. I wish all noobs did this much research before flashing a phone, instead if doing it wrong, bricking it, and the. asking why lol. Your plan will work, u can flash the tmobile radio in cwm, same as u did the rom, skyics is fine, and u only have to unlock phone once. Little tip though, once u flash and root and all that jazz, in wireless settings set mobile networks to gsm/hsdpa only, no lte. This will help battery
You will need CWM before you can make nandroid backup and flashing roms.
Follow this --> http://forum.xda-developers.com/showthread.php?t=1340526
Guide will help with rooting or flashing custom rom right away (which should be rooted already).
Radio is also flashed through cwm just like custom rom.

[Q] Sensation XE no signal on a Particular Carrier

Hi All! We've been working with this issue for 2 days at our help channel #helpmenow.
I currently have an s-off 1.27 hboot sensation XE running Insercoin v 2.0 ROM.
My issue is I don't have get signal for a particular carrier. (Other SIMs for other carriers works just fine). This carrier used to work before, I was just charging and then I noticed that it got no service.
These are the steps that I took so far:
1. Check antenna at the cover
2. Tried SIM on another phone (SIM Works)
3. Tried a DIFFERENT SIM from a DIFFRENT carrier, it works fine on MY phone.
4. called my provider but no issues on their side.
6. used RUU
7. tried RIL's
8. Flashed old 1.17 firmware to clean radio data.
9. Flashed a different ROMv with and without full wipe
10. Also tried downloading apps to enhance signal but to no avail.
we've been working this out with ganesh007, kgs1992, T-Junk, David_ and others on the channel but as of now I still got the same issue.
Hopefully you can help us figure this out so it could be of use to others who might have the same issue in the future.
PS: Right now I am using a different SIM from another carrier so as to get the phone function of the Phone. The carrier you see below my name is the one that is having issues right now.
Thanks in advance.

Kabayan, we are on the same boat. I have the same exact issue..Sensation xe(2nd hand), originally from Singapore(Singtel), went as far as going back to GB stock. At first, I thought it was just sim locked to Smart, but when I tried a Sun sim, it worked. At this point, I do not know what else to do. Tried cleaning s58,tried firmwares with different radio's, etc. After reverting back to GB and putting in a Globe sim it still says "Your sim does not allow a connection to this network" and no signal. If you got any updates, please let me know. Okay?

Straightforward guide to getting your Galaxy S2 SGH-I727 ICS on T-Mobile

Pre-requisites:
a) Rooted
b) CWM Installed
c) Sim Unlock Code
I could not find a straight forward way to get the ATT SGH-I727 Unlocked and working on T-mobile so I thought I'd make this short list of instructions for those going through the same trouble.
The first thing I had to do was unlock the phone. I contacted a local company that charged $35. Free options failed. Expect to pay. There were mentions of calling ATT for the unlock code which I did, however, the CSR looked up the IMEI and determined that the unlock code was not YET available. From what I gathered, because the original phone owner was still under the two year agreement, this unlock was on hold until that time period was up. Those that bought their phone outright without a contract are provided their code with a call to customer service.
With the phone unlocked, I still couldn't get the phone to connect to a T-mobile signal. With a tmob sim, either a no-signal icon appeared or the phone simply showed full ATT bars but wouldn't allow T-mobile use in options. Also, *#simunlock# would generate a com.android error.
Finally, the following formula allowed for an unlocked phone picking up T-mobile signal:
1. Install the STOCK ICS UCLF6 4.0.4 - UNTOUCHED - rom following the instructions on that page impeccably.
2. Install Busybox (may not be necessary)
3. Install UCLF6 modified boot Kernel
4. Install T-mobile compatible radio - Blaze_4G_LB7_ICS_Radio_MOD worked for me
Boot it and see if you have a signal. You may need to go to options and manually choose T-mobile.
After that, I was able to install a different ROM. I chose SKY-ICS 4.2F6-2.6.1
With any new rom, you will still need to flash a tmob supported radio.
My s.o. will be using this phone, so I won't be messing with other roms, unfortunately. Let me know if you have a fast and stable configuration.
I hope this helps.
Actually as the radio is deeper than the firmware we flash normally you should only need to flash a tmo radio once unless a rom has radio built in most all roms do not

Does it make a difference whether I install the stock ics and kernel you provided? All I did is update the phone to ics via kies, install a recovery, flash superuser, then installed the blaze 4g radio. Would it make a difference between doing what you said and what I did?

It works, but its very crappy, sometimes connects, sometimes doesn't, even followed this post's instructions, still has crappy connection
For those who have T mobile fine on the Skyrocket , how much DL and UP speeds are you getting (and compaired to true T mobile phones data speeds) ? I heard some say they never get more than ~1 or 2 mbps which sucks TBH
Heard this is the hot T-Mobile skyrocket radio.

Are you trying to get Call/Text connection or 4G HSPA+ Connect?
Works on WIND too!
I spend a while trying to get this phone working on Wind (Canada's 1700 AWS carrier, similar to Mobilicity / TMo). I've finally succeeded by doing the following.
1: Install latest ICS STOCK
2: Use CWS to flash AT&T UCLF6
I have not been able to get nearfield working with this modem, but it's working great other than that (albeit somewhat slow UL/DL speeds, but that's likely a more wind's crappy network than the phone). Let me know if anyone has any ideas regarding the Nearfield issue.
Just wanted to share. I have been made so freaking happy by the fact that this worked
I bought my SR for full price (549.99) months ago and stupid att also saying my unlock code is not available yet !!

[Q] Custom ROMs/install guides for XT1028?

After months of being stuck on my Verizon Moto G with a locked bootloader, I finally managed to obtain freedom via the recent update to the SunShine app from jcase. My phone was having some issues prior to unlocking, and it took me several hours of labor and installing/reinstalling things to finally get TWRP and any ROM going properly. I've worked with Android tablets and custom ROMs before, but this is my first time on a Verizon phone.
I managed to get the N5X ROM installed and running, but I couldn't seem to resolve issues with data/mms, which I presume are APN related; trying to enter new APN settings in that ROM wouldn't save for whatever reason, either. For now, I'm back on an optimized stock 4.4.4 image until I can get that figured out.
My question: Is there any list of custom ROMs that do specifically work with a Verizon CDMA/XT1028 Moto G? Does anyone have a guide to getting these ROMs working on Verizon prepaid service, including any APN adjustments that need to be made? Thanks.
Followup: Still trying to figure this out, but the N5X ROM will give me working data if I enable Data Roaming. I've attempted to update the PRL for Verizon via *228, but the phone status still shows as roaming even though my PRL has been updated, displaying my network as T-CDMA 64. Is this simply an issue with my phone not properly identifying roaming/non-roaming due to the custom ROM? Verizon has the best coverage in my area, so I want to make sure it is connecting to the proper towers (and I'm not ACTUALLY roaming). Thanks.

Verizon M8 unlocked w/ TMO sim, same flash process?

Hello, just upgraded from a Galaxy S4 on T-Mobile to an unlocked Verizon HTC One M8 handset. Popped in the sim, I can send and receive text, data on HSPA/3G mode but not one LTE or Global mode (anyone know why this is? I'd like to be able to use t-mobiles LTE and not just HSPA/3G), get the usual "sim unknown source" stuff. I am wanting to flash Skydragon.
My question, is there anything special I need to do before/after I flash these, since I'm using a different network than what the handset was originally supposed to be on? Maybe I need to flash different radio? This is my first time using an unlocked phone, previously all my phones with custom ROMs were on the same network as the handset variant.
Otherwise, would I just update to the latest 5.0.1 OTA update from Verizon, root/unlock bootloader, install TWRP, then flash Skydragon, and I'm all good?
Edit: Well, further reading seems to indicate to me that it turns out verizon M8 devices already updated to 5.0.x are still not able to be rooted at this time?
Thanks for the help
