I am having a very strange issue:
Whenever I am at home, and my G1 is connected via 3G, I cannot use data or make/recieve calls. If I enable the "Use only 2g networks" checkbox, it reconnects via EDGE and works perfectly. I currently have a service request out with TMO which should resolve in the next 24-48 hours, but I was wondering if anyone had heard of this issue.
TMo has no idea why I'm not getting signal, the problem continued even when I reverted to stock "Cupcake".
Things I've tried:
Reverted to stock firmware and unrooted phone (Didn't work; same symptoms)
Call T-Mobile, they removed and re-added me to network. (Didn't work; same symptoms)
Swapped SIM card at T-Mobile store (Didn't work; same symptoms)
T-Mobile service request in my area (Results pending)
Things I am going to try, but haven't yet:
- Return to stock firmware, reinstall CM 4.2.7.1
- Try an older CM like 4.2.4 or 4.2.5
- Connect to WiFi for data connection, see if this replicates the problem as with 3G
- Enable data roaming.
The fact that it only happens at home leads me to believe it's not a problem with the phone, however I'm more than willing to do more to rule it out.
Phone Specs
T-Mobile G1
Firmware Version 1.6
Baseband Version 62.50S.20.17H_2.22.19.26I
Kernel Version 2.6.29.6-cm42 [email protected]
Mod Version CyanogenMod 4.2.7.1
Build Number DRC83
Dont tell T-Mo that your rooted thats a big mistake right there, that can be used against you if you ever have to get the phone replaced.Play around with the apn settings and make sure "always on 2G" isnt checked in settings. Maybe your house isnt in the small 3G coverage area, or your phone cant connect to it. Why would you think data and talking at the same time would be possible? Its either you answer or you stop browsing the web.

Yes, thank you, I know not to tell them that, they have zero idea. I also forgot to mention they did swap out my SIM card at the store.
Read what I posted. Turning on "Always On 2G" is the ONLY WAY I can make calls and use data at home. When that isn't on, the phone says it has a 3g connection with four bars, but will not dial out, take calls, or connect to web pages. I've also verified my APN as epc.tmobile.com which is correct, and this affects my voice and data communications.

Try another rom to confirm you cant get 3G, it could also be HW failure.But just try a older cyanogen or something else.Ive cant get a 3G signal with cyanogen roms for long but with a hero rom i seem to get 3G(maybe its my imagination)

It fails on both stock (untouched, unrooted), and CM. I'll try an older CM just in case though.

Rebooted phone between each of these tests:
3G With WiFi enabled: Same result, can't dial out.
Data roaming enabled, Wifi Disabled: No signal at all, 0 bars with "X" symbol.
Stock firmware: 3G won't dial out, forcing 2G works.
Downgraded to CM 4.2.4: Same symptoms.

What ! if you have 3G coverage you can talk and access data at the same time.
That is what 3G provides.

That's not what I'm trying to do! When I am at home, on a 3G connection, I cannot do ANYTHING. That includes text, voice, data, web, ANYTHING. If i force it to use Edge, all services work properly. This is not acceptable. T-Mobile's coverage map lists me as in a strong 3G area. It SHOULD work.
I dont know what to say, except stay on edge, you alreadt sent a req to tmo.
I am having the exact same problem. Would love to learn what you found out.
Any solution?
Only GPRS/EDGE does work, if 3G is available, it disconnects automatically until 3G isn't available.
Solution: Set to 2G-Only :-(
Anyone has the same problem?
I didn't have this problem with FRF 72.
Provider: Sunrise Switzerland
Radio: 32.36.00.28U_4.06.00.12_7
Have you tried going into your phone settings from *#*#4636#*#* and setting it to wcdma only? I did that on mine not too long ago and no more dropping to edge for me!

does it lose complete signal? or does it show 3g still but just not doing anything?
Mine was working at first after flash. Then at about 2am it just kept trying to load then times out. Still shows 3g but just dont do anything. Im hoping its just tmobile messing with their towers... I dont see why it would work at first then not now..
The problem is, that i can only have a internet connection, when the phone is logged in into a gsm or edge network.
as soon as wcdma is available, the phone disconnects from the internet.
the signal is always available, but it looses the internet connection when it changes to 3G mode.
when the phone changes from 2G->3G mode, i see for 1s the 3G icon and then no icon will bi there.
when it changes back from 3G->2G, the EDGE/GPRS icon is visible again.

ok thanks for clarification. My problem is different. I think related to phone company.. I still show the 3g signal and even have bars, but the pages dont load and eventually gives me the check your service and try again alert....
So Im hoping soon its working again for me... And I hope you as well figure it out.....
Thank you Good luck!
Had the same issue after update, did *#*#4636#*#* and noticed I was set to GSM only. Set it to WCDMA preferred and now it's good.
Thank you very much, thats the solution!!

Thank you. Updated to FRF83 this morning and I've had a full 3g signal, just couldn't pull data all day. Could over edge. Sure enough, GSM only was selected.
AT&T N1.
I'm having the same issue on a non-rooted phone on T-Mobile. No 3G after the FRF83 update. Full bars of service and 3G displayed in the status bar. Dropping to Edge only works but there is no data with 3G.

Same issue here.
Switching to WCDMA preferred doesn't work for me though.....any help is welcome
I think it's a hardware problem with a lot of N1's.
Mine was ok the first 2 months, and later, 3g not working. This is driving me crazy ):
I have tried everything. Change the simcard, I did a reset of the data with my telcon, and nothing happens.
I've seen these problems on many N1's.
I hope google / htc release a fix for this problem.

how bout checking your bands in the service menu. so *#*#4636#*#* -> phone info -> press the menu key for more options -> select bands -> choose one appropriate for your region (ie "USA BANDS").
If all else fails do a factory reset by going to the settings -> privacy -> restore factory defaults.. of course do a backup/sync/whatever before just to make sure you can get all your apps back.
There's other ways to do a factory reset via the bootloader .. its under recovery and you press up volume or the trackball I think and you can just select all the clear/erase settings there and that should clear out everything on the phone's internal storage.
The factory reset worked for me (via bootloader) when I upped from update-1 to FRF50 and didn't have any data icon next to my signal strength. Could call out but couldn't get data.
Hope that helps.

Check your APN settings. Do a full factory reset from the bootloader. If nothing works you should call tech support again. Most 3g issues where you have issues with connecting are service/signal level related. I *****ed early about my 3g issues on tmobile and it was the network as they've pretty much gone away with improving the backhaul in my area for HSDPA+ or updates to the phone's radio.
HTC is really really really cool about swapping phones and repairing them. If you feel you have a nexus that has hardware issues call them. I did this 3 times already (one time for minor cosmetic issues with the refurb they sent) and I couldn't be happier about how willing they were to replace/repair the phone. It turns out I really didn't have any issues with them at all.. with any issues with hardware from the second refurbished phone. It was service or software related and I'm happy to say with updates/tmobile service improvements I couldn't be happier with this phone.

Thanks blisk, but the thing I don't understand is why Blackberry 9700 with T-Mobile bands, doesn't have problems at all ?
By the way, I rooted my phone , so the thing with the warranty it's complicated
I had it happen last night at work all night, but when i got home i checked my wife's tp2 and it also was doing the same thing so for levity wasn't the phone but tmobile. They started worming the same time also.... I think its tmobile.
Hello, I had the same problem with my imported n1. I'm using the tmobile version non rooted fully stock manually updated to frf83. I did a *#*#4636#*#* and selected wcdma only, rebooted and couldn't connect to my gsm network. Went in again and did a wcdma preferred, rebooted, and I works better, still changes fast to edge and G, but less often, I'm still trying it but I have high hopes its gonna be ok
Mmmm i did have problems with 3G too after pushing FRF83, but i found out that for some reason the APN settings weren't set correctly after the update. In my case the port setting after the proxy of the APN wasn't set, i changed to the correct value and it worked.
In conclusion, check your APN settings.
Just went from FRF72 to FRF83 and it's working fine.
I'm currently set to GSM auto (PRL) in the *#*#4636#*#* and I didn't change it to that after putting on FRF83.
I'm getting a chance to do some extended testing with data roaming. I found a couple of other data roaming problem threads, but this issue is different than the problems discussed in those.
The HTC One is rooted, unlocked, S-OFF, stock 4.4.2 (4.06.651.4), with PRL 56018 installed from CDMA Workshop. I've installed a couple of the patches floating around for WiFi tether. I also have an HTC EVO 4G LTE with the 56018 PRL installed via QPST.
Right now, I am in an area with extremely weak Sprint signal and decent Verizon signal. The EVO 4G LTE finds Verizon 3G EVDO and will voice/data roam just fine. SignalCheck verifies that the provider is Verizon for 1x and EVDO, with signal between -90 to -100 dB. However, the One will not data roam. SignalCheck indicates that the One finds Verizon for voice (1X), but does not connect for data roaming. If I watch SignalCheck long enough, I can see that the One will find the Verizon EVDO for a few seconds every five minutes or so, but it won't "hold" the EVDO signal. On Sprint, the ONE will find both 3G and 4G.
I've played around with various mobile data settings, but nothing seems to help. In fact, the One will pop up the messages that data roaming is in effect, but there is no data connection. Since the EVO 4G LTE will EVDO roam, it seems that the One should EVDO roam as well.
Any ideas or suggestions on what to look at? On Sprint the 3G is usually ePHRD, not EVDO, perhaps there is some issue with EVDO on the ONE? I thinking about getting Roam Control to see if that would make any difference. I haven't taken the 4.06.651.9 update either.
Thanks!
I had a chance to do some further data roaming testing with the One and Evo 4G LTE side by side.
Roam Control seems to work fine on the One, except that the color of the blue button for selecting the roaming mode is hard to distinquish.
Unfortunately, it seems that the One will not lock on to a Verizon EVDO signal. I found several areas with strong EVDO signal. The EVO connected just fine, but the One wouldn't. The One does fine with Sprint's eHRPD signal, and will lock on to the Verizon 1xRTT for voice.
I don't know how to do further debugging. I guess it could be a radio problem, an issue with the 56018 PRL and the One, or some other issue.
Any suggestions are welcome!

Providers dont like roaming, the newer the phone is the less likely it will be to roam, the first two M7 radios would not allow any roaming at all on my phone, the latest 2 do allow roaming but I need to force "roam only" with roam control, I am on the latest radio running GPE rom and use roam control to force roaming whenever verizon has a better signal and it works good. I am using PRL 56015 flashed via CDMA workshop.

Unfortunately, my One will not data roam, even with Roam Control. It sees the EVDO for a few seconds, but won't hold it.
Would there be any tweaks that could be made to the radio from CDMA Workshop that might affect the data roaming behavior?

I loaded PRL 56015 into the One with CDMA Workshop, but the problem remains...when roaming, the One will see the EVDO briefly but not hold it, according to SignalCheck.
I did a comparison between the various settings in the One and the EVO 4G LTE (where roaming works fine) using CDMA WS. The are significant differences, particularly on the CDMA, CDMA-2, and EVDO pages. For example, on the EVDO page, the EVO has a username ([email protected]) for HDR_User_long, but the One doesn't have one. The EVDO revision is also different. I don't know enough to fool with these settings.
Actually, the One is missing values for many settings that the EVO has. I'm beginning to wonder if somehow the One didn't get provisioned properly.
Thanks!

If you change any of them settings in CDMA workshop, save them first, if you screw something up you can reload the saved settings, I screwed with CDMA workshop alot in the past and you can do alot with it. Before screwing with them settings, did you try resetting or updating your data profile?..maybe something got messed up in the tweaking and flashing your doing. I flash all kinds of different stuff on my phone, every once in a while I flash a sense rom and update or reset my data profile just in case...

I am not on a sense rom right now and I forget the codes, try entering ##3282# or *#*#3282#*#* in your dialer, it should bring up a data menu, there should be an option to do a reset, it will basically erase your data profile and reboot, when it reboots it will do an activation and reset everything....or ##786# will completely reset everything, that has saved me once or twice but that also factory rests your phone. these will only work on a sense rom and I reccoment a backup before doing anything, just in case... if that dont work do a google search for epst codes, and find the one that resets your data profile.

I did a profile reset with ##3282#, and the behavior has changed somewhat. The One is now holding the EVDO signal according to SignalCheck. However, if I try to open a web page, a message box pops up indicating that data roaming needs to be enabled. If I tap on "data roaming" in the message box, it takes me to the mobile data settings. I have been over and over those settings, and tried different combinations of things, but I can't seem to come up with the magic setting that will make the phone think that data roaming is enabled. I am forcing roaming with Roam Control.
Is there some "hidden" setting to enable data roaming? There is a "CDMA Roaming" setting that has choices of Home/Automatic, and I have it set to Automatic. I have identical settings to the Evo in the mobile data settings, but I can't make it work on the One.

What rom are you using?, I think the stock roms from Sprint no longer have the "allow data roaming" option, Sprint tries to avoid us using roaming as much as possible, so if you are on stock rom or something close, you probly don't have this option, try flashing a modified rom that may have this option, or if you are familiar with using the exposed framework, I think there is a module you can use to enable the data roaming. I personally use Gruesomewolf's GPE rom and it has the option built in if you want to try it.

I'm on the stock 4.06.651.4 ROM (rooted and S-OFF). This is my wife's phone, and I'd like to keep it stock and simple, as she's not a techie. However, she also travels where data roaming is required, so I might have to try another ROM.
Interestingly, My EVO 4G LTE doesn't have an "allow data roaming" setting under mobile network settings that I can find, but it roams just fine. In fact, the mobile data settings on the EVO and One are almost identical, except that the One has some additional GMS options. I wonder if there is some setting in a file like build.prop that affects data roaming.
I installed a couple of native hotspot hacks on the One. In looking through the zip files for those hacks to see what they actually did (which was quite minimal), some network-related things were changed in /system/customize/ACC/default.xml relative to the file in the original ROM, and a shell script was added that executes several iptables commands. I may try to manually undo those hacks to see if it has any effect. At this point, we need the data roaming more than the hotspot.

Alot of your issues can be solved with a custom rom, you wouldnt need to install the hotspot hacks either, most have native hotspot built in.

Getting a chance to work on this issue again...it seems that the EV-DO problem with my HTC One is not limited to roaming, but also occurs on the Sprint network.
Again, doing side-by-side comparison between the HTC One and my EVO 4G LTE on Sprint network:
1) Set network mode to LTE/CDMA. According to SignalCheck, both phones will find Sprint LTE and display the 4G indicator in the status bar, and both will occasionally drop back to Sprint eHRPD for periods of 5-10 minutes (displaying the 3G icon in the status bar). Network is available to apps in both the LTE and eHRPD cases. No problems here.
2) Now...change network mode to CDMA Only. According to SignalCheck, the EVO will find Sprint EV-DO, the status indicator will change to 3G, and network is available to apps. However, on the One, SignalCheck indicates that EV-DO is found (but doesn't indicate which carrier), there is no 3G (or 4G) icon in the status bar, and apps report that there is no network. The EV-DO signal is strong for both phones.
So, it seems that on the One, LTE and eHRPD are working, but there is some kind of problem with legacy EV-DO, where the phone can find a signal, but can't complete the process of registering on the network, whether Sprint or roaming.
Do eHRPD and EV-DO use the same radio? Trying to rule out a hardware issue. I am thinking of flashing a different radio firmware. Perhaps something got corrupted when I did the OTA update.
Not that Sprint wouldn't do this, but it would seem odd to put something in the stock ROM that would prevent EV-DO, even on Sprint's network. Is there somebody out there on the stock ROM who could confirm that they can get network in CDMA only mode?
Thanks!
So, I finally got this problem solved! I had to do a ##786# "hard reset". After the reset, EV-DO works fine.
The reset process was interesting. I did backups, expecting the phone to be wiped. I entered ##786# and the phone said it was preparing, and then rebooted. But it rebooted into recovery (I have TWRP). Not being exactly sure what to do, I rebooted into the system. The phone booted up, and the provisioning process started and completed. It then fetched the PRL. But nothing was wiped out. Apps, data, and sdcard were all intact. Oh, well, no complaints, and everything seems to be working fine. I used CDMA workshop to put PRL 56018 back, and roaming seems to be working.

I know you got your issue fixed and its been a while but just a heads up in case you run into problems again, I got a replacement phone from sprint and had the exact same issues youe were having, It is a problem with the data profile not being configured correctly, in my case, the new phone did not have my user name correct, worked fine on sprint network for some reason, but I couldnt get 3g in roaming areas, using epst I put my correct user name in and everything worked perfectly...dont know what rom your running now either but NUISENSE is awesome with this phone and it has "roam only" opttion built in, no need for roam control app....
Thanks for the tip!
I'm using the stock ROM. Since my last post, I have been able to test romaing, as we've traveled off the Sprint network, and roaming 3G worked fine. The only issue was that in a one spot we were roaming on a regional carrier, and the phone had locked on a quite distant tower according to SignalCheck, instead of Verizion which had closer towers. This resulted in some loss of 3G just as we were trying to get radar data for a storm we were traveling through (bad timing). But that is most likely a PRL issue. In looking though some PRL analyis an earlier version of 56xxx on another site, Sprint apparently doesn't have roaming agreement in this particular area with Verizon. I wish I new more about PRL editing so I could fix that...
I have a M8 from day one, FA device number, s-off, HK RUU, rooted. Never had a issue. I'm living in a LTE are and working in NO LTE are. I always set my phone to CDMA only when im working. Today I have no call, but i made call. my wife was calling me all afternoon and she said is going directly to voice mail. So i got home I start testing my phone. My result is im not receiving call when i set to CDMA only, but yes i receiving call when i set to LTE/CDMA. LTE NO spark area
Do you have Google Voice?

Yes. but i disconnected from my phone while i was doing the test.
Update: I drove to no LTE area and No received call at all. one's i get to LTE area my phone ring right 2 second after hit call button
You lost 3G like I and some others have.
You need the phone replaced.
It's not your towers.

issue resolved: go to /setting /system updates /Update profile, after finish reboot. My phone now is back to normal.
Glad that worked for you.
I have updated profile and PRL numerous times tho to no avail.

So did I and much more. RUU, ##786# -> Reset etc.
Have had my phone since Saturday and it has been fine. Now I can't keep a data connection for the life of me. I used to have LTE and spark everywhere now it says 3g and can't connect to network.

I'm also having some trouble keeping data connection...I know I used to have LTE/Spark but now I barely have 3G and a bar
The short:
I changed the "Select radio band" setting in the test menu (*#*#info#*#*) and it screwed things up.
I wiped and reflashed CM12.1 - but it didn't reset that setting (it's still borked).
Does anyone know where it stores that setting, or how to reset it somehow?
The long:
Initially in CM12.1 I was having problems staying on LTE - it always fell back to 3G and stayed there.
So tried this band change that someone who had the same problem suggested.
Now, every option I try is great for LTE but says "cellular network not available" and I can't make calls.
The exception is "Cellular" which I can make calls but only get 1X data.
These are the options in the menu:
"JAPAN Band (WCDMA-800/WCDMA-IMT-2000)"
"USA Band (GSM-850/PCS-1900/wCDMA-850/WCDMA-PCS-1900)"
"Cellular (800-MHz)"
"PCS (1900-MHz)"
I don't know what it was before and I can't see figure out how to tell what it currently is set to.
I just want to flash back to stock so things work again, but if this setting doesn't get reset then I don't know if that will work anyway.
Any chance settings like that are stored on the SIM card?
try to re-flash radio only

Worth a shot, but doesn't seem to have helped.

I seemed to have luck when I made the changes according to this post and then immediately ran the ping test. I don't know if the ping test really did anything to help but I've had cell service since following these steps.

Unfortunately that's what I did initially. The setting in that link ("Cellular") made my calls work, but I could only get 1X data.
So somehow by just flashing and reflashing different things (including failing to reflash to stock), it's back to where it was when I started.... which sucks, but is at least useable. Calls work and data works, but the first time it has to drop back from LTE to 3G, it get stuck in 3G forever (until airplane mode). Super sucks since it's my primary home router tethered. I have to airplane mode like 5 times a day.
Just in case someone else ran into this problem, I ended up getting a new sim from Verizon and everything's working now finally. It still says "000000" when it's in 3G, but I don't care about that - it works and it goes back to LTE when it can, rather than staying on 3G forever.
Works for Moto X play - should work for others too..
I too did the same mistake. Changed my Band to "USA" and couldn't restore to previous despite Factory reset.
The SIM 1 went into 4G data only (No voice) , didn't recognize 2G & 3G network for any sim.
However Sim 2 worked fine for 2G,3G & 4G.
i came across a thread in XDA, and after breaking my head over how to execute it, I finally did it.
I have written a brief guide to it. Here's the link.
