My 3G randomly dies and I can only use 1x. I know the fix, but what ROM supports it?

Had my TB for about a month now, everything was great till my 3G decided it didn't want to work. It just died completely out of nowhere. So after googling,I found if I dial ##778#, I can reset my modem and my 3G will come back.
The first time it died I was on Das BAMF 3.0 RC. Dialing ##778# did not work. I just got a FC. So I said screw it and unrooted my phone and flashed the stock froyo ROM back. Used that for a few days and my 3G died again, so I tried ##778# and it worked, I got my 3G back. I figured it was a random bug, so I put a different ROM on - samething happened: no 3G, ##778# doesn't work. Since it died again, and I didn't have access to the menu to reset it, I had to unroot my phone again. So then I rerooted but kept the stock froyo rom on just in case (since I knew I could reset the 3G here). Everything is good so far...
Only problem is, I don't really wanna use the stock rom. Every rom I've tried doesn't seem to have ##778# working... do you all know anyway to access that menu other than dialing? Or a different way to access it on other ROMs? Thanks!
tldr: What ROMs allow me to dial ##778# to fix my phone loosing 3G randomly? Everyone I've tried I get FCs

There is an app called phone info that allows you to do the same thing and should run on any routed Tbolt.

LTE onoff is an app for the thunderbolt that puts you in the menu you are looking for also. If I remember correctly its from team AndIRC plus its free and works great

Thanks for the replies, but that's not the menu I need to access... I'd post a link but I can't since I have less than 8 posts. If you google "EPST thunderbolt" and go to images, you'll see what I'm talking about

i just tried it works on gingerbean but i hit edit it tells me enter code does anyone know the code is thankxs

[Q] lost data connection

First, I'm not too familiar with how ODIN works, so I'm a n00b to Samsung Galaxy S stuff. I'm used to HTC and LG. This is my fiancee's phone.
She has lost data connection. Rebooting, reregistering, turning airplane mode on/off doesn't make it come back. WIFI turns on and all that good stuff.
Here's what's currently running on her phone:
Firmware version: 2.2.1
Baseband version: T959VUVKB5
Kernel version: 2.6.32.9
Build number: FROYO.VUVKB5
Yes she has root. What would I need to do to get this back? If it involves flashing another ROM (been thinking about getting her on Gingerbread) than that's ok I'll just need pointed to a good guide for Galaxy S n00bs.
Thanks in advance for the help.
I'm also not sure if she has clockwork flashed or not. The phone was purchased used and was already rooted.

First go into settings > wireless and networks >mobile networks > and make sure packet data is on, if it is, go into access point names hit the menu key and click reset to default.
Make sure network mode is set to gsm/wcdma (auto mode) if not try switching between the other two options and see if that helps.
If none of that works:
You can try to Odin different modems.
http://forum.xda-developers.com/showthread.php?t=1192436
Try the KD1 modem first and see if she can connect.

I tried the settings already. No luck with those. I will read up on ODIN and try flashing those modems. Thanks.
Might just take the plunge and flash Gingerbread for her, but she hates restoring apps and stuff. lol

I tried that modem. Same issue. Any other suggestions? I'm open for any other ideas. Nothing has changed on the phone. No new ROM, no weird apps. Same geographic area.
I'm at a loss right now. I've never had this problem on any of my phones so I've never had to troublshoot/repair something like this before.

Sorry about the late reply. The IMEI shows up normal. It worked perfectly for a few months, and has only been acting up for the past week or so.

Are you sure your APN settings are correct? for some odd reason, I had to manually set the APN's for my carrier.
Try disabling wifi, as it won't get data connection otherwise. Then go to settings, wireless and network, mobile networks and then Access Points Names.
See if the carriers APN are all set correctly. Should be t-mobile's unless it's an unlocked phone with another carrier.

are you sure that the imei's fine? or is it a generic imei?
i know this situation all to well, my efs folder got f***** and i had a back up on my sd card but as luck would have it my sd card was wiped. and ever since then i could never get a signal on the phone.
so make sure its not that issue because honeslty if it is theres not a thing that you can do about it.

The IMEI is correct. It matches up perfectly. Sorry for the really late reply.

So IMEI is correct and data packets are enable?
Do you have a data plan on the phone? Check my.tmobile.com. If you do call tmobile and *****!

Yeah data packets are enabled.
Gotta check those APN's, though. Been looking for what the settings should be.

APN it was!
Thanks! Problem is solved and her phone works fine.

I "lost" my data connection last week and spent hours on odin... N It turns out that I just forgot to pay my bill... I felt like such an idiot =P

Data speed icon?? Gone?? Invalid Sim sometimes??

Okay I have been having the t-mobile "invalid sim card" issue and the phone currently is running with the t-mobile carrier logo. I was able to make calls, and connect via WiFi. I am not able to access the web2go page when I select data in the "wireless & network settings" page with a check. I used to be able to at least access this page with wifi turned off and it would show a little 4g icon on the top? I will post some screenshots. I downloaded GeRIL just to see what it said? I think my phone is rooted? I ran superuser and said the phone was not but the last action I did before getting the t-mobile to show up was a zip restore with CWM so I assume it's rooted? Might be just a flash? One other thing is that I have the WiFi and GPS on and it does not appear to get my location for weather in the weather app?? I can open Google maps and GPS is within 60 meters of my location. I want to reboot the phone but am afraid it won't be back to normal and I will get the error "Invalid Sim Card" again? Is there anything or tests to run while the phone is on the t-mobile network I should check first before rebooting? Or files I should try to use or flash? Or any service menu codes to run diagnostics? Thanks in advance. I forgot to mention that I will be getting a replacement from t-mobile in a week, I did the online chat and they said they will send a replacement under warranty. The box has a date of 7/29/2011 so the phone is about 3-4 months old? The phone is unlocked and has been rooted before, but the issue happened days before I modded this G2x. Basically, today it could connect and tomorrow it might not...or If I reboot It usually goes to the "Invalid Sim Card" I have read other posts with issues of the same type from other users but found no solutions?? Baseband, RIL, Sim ect...all points to a bad phone(using t-mobile) because If I use any other carrier card in the phone it works without errors. That makes me think it's a firmware with t-mobile issue but I could be wrong? Hopefully if the replacement goes thru the same ICS 4.0 will be out and make this phone a beast again?

This might work or it might not: rename your APN manually (Settings/Wireless/Mobile networks/Access Point Names/edit) you can either edit or restore to default to restore mobile data connectivity. Try restoring to default.

I just accidentally hit Airplane mode and it killed it!!! Now it's back to the Invalid Sim Card error again...bummer!!!!

Wait a minute...I waited and read a few posts and clicked the Airplane mode off and on again and it came back to the t-mobile carrier..??? I still have not rebooted the phone though? Hmmm...should I?

Did you get a new sim card when you got the phone? I remember when I got this phone they told me not to use my 5 year old sim card from my previous phone. I say try a new sim card, if that doesn't work try to reset the apn with the instructions I posted last, and if that doesn't work it might just be a bad sim card reader.

I think more on the lines of a bad sim card reader...I have a new sim card...about a 3 days old, got it from t-mobile cause i had the older sim with the larger gold contact patch. The phone is already on order...they said 7 business days..

Same issues here

Yes some times that will work. Other times might take 2 reboots. Also sometimes toggleing airplane mode can bring back apn. After a few sim cards and all my problem went away. When I had the issue I was cm7 rom. Stock Rome didn't really seam to have this issue.

just to close this thread I already received my replacement phone from tmobile. I am no longer trying to track down the issue. Thanks for all of the replied and comments. every one who contributed will get a thanks from me.

Yes doing a hard reboot will reset the Apn/data loss problem. (Also toggling airplane mode would some times reset it.) This is only a tempory solution as it could happen again. On cm7 rc1 it would happen to me at least once a day. As well as many others. Off of the top of my head it was something wrong in a radio file.(? Not sure what file) shortly after the release cm7 stable 7.1.0.1 was posted. I believe that had the patch for the data loss issue. It is possible that some cm7 based Rome may still have a data issue loss as they might not have the updated patch. At the time stock based Roms did not have the issue and as far as know. Some people faced with this issue could have had a faulty sim or phone. The other thing that was happening during the life of this issue was how many people running cm7 based roms didn't have the issue. I no longer have this issue. I followed the bug report that was submitted and sealed out the sim card twice. (I think it was cm7 issue on my device) OP- I hope that this swap works for you. If it don't, I will be more that happy to help. also thank you for your service.
I have posted what I know and can remember here in hopes that it can help some one else out in the future.

When I had the phone I installed CM7, and the daily's...ect..It WAS a phone issue (hardware) I now have had the replacement phone for 1 week and no issues what so ever. That's not to say that the issue will arise again? I have rooted and am running no ROMs at the time but am thinking of going back to the FROYO 2.2 just to get the camera like it was in the older version. I hate the camera in GB 2.3.3. No zoom....c'mon LG..where did you guys lay down to sleep during this process if the development? One other feature that has nothing to do with the camera that I would like to see happen is to be able to enable a bluetooth mouse. I tried my Targus mouse and no luck. I think you can use a bluetooth keyboard but have none to test. I was thinking of shelling out the 160 smackers for the infared keyboard..small and can fit in your shirt pocket, and it's bluetooth.

[Q]3g is popping on and off like it wants to start up but doesnt and no connection??

i have no clue what going on here.. but i dont have any data... but voice works fine.. ive done multiple reboots.. running opensensation..
anyone knows whats happening?
im running the 30.00 prepaid 5 gigs of data plan

You can change your data connection . Example my device always wants to go to edge, which is really slow so I lock on to wcma only which is 4 g. You can try the different connections by going to #*#*4636*#*# it will bring you to a menu you press phone information, then press your current connection and another menu will come up with available connections, pick the one you want and scroll down to refresh . I'm not sure this will do the trick but if you have any available connections you can hook up this way. It depends what's available in your area .I was going crazy with my device always going to edge so Iocked onto 4 g this way. It works for me. I do hope it helps. Are you rooted and running custom Rom? If you are and this method does not work perhaps try a different radio? Best of luck hope this helps some

im rooted running open sensation running the latest firmware so i shouldnt have to flash a radio its been working before.. for the past month i had my phone.. this is the first time its doing this..
ok im gonna update and wipe my dalvik.. see if that works
EDIT: nope.. still no data..

It's *#*#4636#*#* sorry I had that wrong in my first post
Sent from my HTC Sensation 4G using xda premium

yeah that still didnt work.. and this is really troubling me.. i posted in the opensensation thread..

I had the same problem with roms based of CM9. The only solution is to back up everything (titanium backup helps with backing up apps), wipe and re-flash.

No need for wipe.
Just re-flash the current ROM. You will have to apply all your Mods again, but the rest of the data will remain fine.
(I had the same problem about two days ago)

Radio problems do not come up all of a sudden.

Yeah i fixed it.. I had to backup and then restore my tmobile stock rom.. Then restore my cm9 backup.. Seemed to fix it but wow that was weird..

Its happend to me after i flashed somthing. All i did was put it in Airplane mode and rebooted. After reboot turn off airplane mode. Got everything back.

JB 4.1.1 Won't connect to tmobile towers

It updated OTA on it's own and was working last night. This morning I looked at my phone and it was connected. I moved it and it lost signal and hasn't gotten it since. I can't force it to connect, will get roaming but roaming in this area is emergency only.

Just did that. Still nothing.

Ok I've flashed 4.0.4 then CWM to 4.1.1 and nothing. Flashed 4.0.4 and nothing then flashed GB on it and nothing. I'm out of ideas.

Maybe you didn't save properly? Don't press back when done inputting everything, but press menu>save.

If that doesn't work, there's a remote possibility it's a problem with the SIM card. You might want to go to your carrier store and ask for a new one; in my experience this is usually free. Other than that, if flashing a whole new ROM doesn't fix it, I have a hard time understanding how it could be anything other than a hardware issue.

It was the sim card. I wished I would have thought of that before I wiped everything though. Oh well I got a clean install and learned a lesson. Never skip step 3...
