[Q] T-Mobile lost signal after factory flash 5.1 - Nexus 6 Q&A, Help & Troubleshooting

Hey Guys,
I have seen multiple threads about 5.1 having an issue with SMS/MMS. My problem is that I do not get a signal at all. I did a full factory flash to Android 5.1 and now i get no connection what so ever. I have tried multiple combinations with toggling Enhanced 4G LTE mode and Preferred network type and nothing makes any difference. If I flash back to SOKP rc1 5.0.2 it works great. I have the latest bootloader and radio. Has anyone experenced this or have any tips?
Thank You,
DFL

Have you tried changing your APN? Try these settings https://support.t-mobile.com/docs/DOC-17581 ... Then delete all other APNs you're not using

@YankInDaSouth yeah, i did do that. after much trial and error i got it working. i ended up re-flashing the radio via fastboot, reset and the data/voice cam in.
thank you for the help,
dfl

Glad you got it all worked out!!

611 works for you?

611 not working for me. On stock rooted ROM.

[Q] Need help connecting to data!

Im new to flashing roms, so bare with me. I flashed my first rom last week, using Andromeda3 and Ursa Minor #2 kernel, everything worked great except, i couldnt connect to 3G/H, even though it showed up on notification bar, tried looking for answers, i ended up flashing different modems to no avail. So, i flashed back to stock eclair, used kies mini to upgrade to Froyo 2.2 UCKB1, Data worked. I then flashed UCKB2 rom, data didnt worked) i tried wiping cache and all that, still no data connection, btw, wfi worked. So i flashed back to UCKB1, again, everything worked perfectly. The other day, i flashed Fusion XI and GB bootloaders, i must say i like this rom very much, but again still couldnt connect to 3G/H, everything else worked, although i havent tested the GPS yet, i am getting amazing DL/UL speeds through wifi. Anyway, i searched XDA for any answers i could find and pretty much tried them all, seems like only KB1 3G will work, but any custom rom out there, data hasnt worked even though i see it in notification area, i'd use market and browser, but would say could not connect. Am i doing something wrong/ missing a step?? I really like Fusion XI and dont want to flash back to stock. Any help would be appreciated.
Didnt know where else to post this, seems like other people dont have the data connection issue :/
That's weird.
Try flashing the kb1 modem on fusion.
I did try flashing the KB1 modem, but that too, didnt work. it only works if i go back to stock KB1 for some reason.
where do you live? what Carrier are you with?
have you checked your APN settings?
fill in your location and carrier/ device info in your signature/ xda user information.
I Live in Southeastern Pennsylvania. And currently have AT&T as my carrier. I tried APN settings, but not sure what to set it too, i have used APN Manager from the Market.
Try resetting ur apn settings to default. Then reboot.

how do u reset apn settings?
Settings, wireless and networks, mobile networks, access point names. Now hit the menu key and reset default apn well be on the bottom left...
Ok, tried that, still a no go connecting to data. I just flashed stock 2.1 then 2.2 update through Kies mini, i no longer have data connection even on official stock roms could this be a hardware issue??? gps sucks. ran a gps test using the app from market. other than that, everything else is working. what did i do wrong?

[Q] unable to get data connection

Hi guys,
I'm being annoyed by my SGS about his data connection. Hope someone could help me!
Few days ago I flashed MIUI Mintberry 2.1.20 and everything was working like a charm, but this morning data connection switch failed several times.
I've tried to wipe everything, re-flash Mintberry and even to flash JVU stock with Odin, but I still can't switch on my data connection.
I can't even see any icon on the status bar.
Any idea? Is my phone broken?

Hmm this is strange, so you turned data on but theres no symbol, right? Have you tried installing another kernel (maybe also applying the Kernel Cleaning Script)?
I' ve tried everything with Odin, and at the moment I have a beautiful black screen of death.
Odin cannot recognize my phone... I'm very frustrated
EDIT: Upgrading Kies'drivers, I managed to connect the phone with Odin again, so I've flashed the lastest official stock firmware to check my antennas. In the worst case, I'll be able to go to the shop for assistance without problems.
Have u tried typin ur apn maually?

Sounds like a settings issue. Never heard of anyone have this problem before - I've flashed every version of mintberry including betas.
I just had this issue
I just had this and figured out what is wrong, its a easy fix too! Just go to settings and wireless and change the access point for your mobile connection. I had 2 access points and just switched it to the other one and my data started working again!
Hope I could help
Hi guys! thank you for all these answers!
I've tried to set APN manually, to change custom ROM and custom kernels and coming back to stock too, but still no data connection icon (neither data connection itself).
At the moment, I'm on JVO, the latest official italian firmware, everything is fine but 3g data connection.
Other ideas? Shall i need of Samsung customer service (I hope no!)?
Solved...
MIUI default settings fault: SMS notification has ran out my money and my provider has blocked 3g connection.
My phone is safe!

[Q] Droid 3 CM10.1 No service Problems

I recently installed both AOKP and CM10, the most recent versions on my Verizon Droid 3. Now, i have no service. I downloaded (via wifi) the app "lte on/off" to get a look at what was happening, and the radio keeps rapidly switching on and off, on and off over and over again. This happened with all the AOKP versions i tried and both CM10 versions I tried. Ive rebooted, re-flashed, tried different download links, reflashed again, wipe and reflash. Im at a complete loss here guys, any help would be appreciated. Thanks!

I had the exact same problem. I went insane scouring the web for hours trying to find a single person with the same problem until I finally gave up. Does anyone know the last version that actually worked?
I also have this problem, do anyone have any idea how to fix this problem?

I had similar problems on cm10.1. I have no idea if this will work (I'm outside the US, and my phone asked me to activate the phone), but I also had no service, no data. I changed my network mode from GLOBAL to GSM/WCDMA auto. Now I have service and data (Data after applying the correct carrier apn settings)
I hope this helps you all
P.S. after this step I made factory resets without the need to do the above step again (You only need to put the correct apn settings again if your on networks other than Verizon)

[Q] Signal Issue

I flashed omars rom about a week ago and everything was going great until this morning. I woke up and have no signal at all. Rang my operator, they said there's nothing wrong with the network. I've tried everything I can think but nothing. I've flashed different roms, kernels and ended up using rsd lite to go back to stock, and still no good. Anyone have any ideas? Any help would be greatly appreciated!!
It can be hardware issue. If flashing full stock rom didn't help it shouldn't be software issue.
Download any app to enter radio settings and change to only 2g but it must be changed in radio settings, not just phone menu setting. If it wint help on stock full rom for 90% it gonna be hardware issue.

[Q][GSM] restore radio in droid 4

Hi I have a droid 4. I bought it in the USA and used it only in Italy. It was rooted and unlocked and it has always been working fine over GSM and 3G. Then I decided to install CM 10.2.1 and then i upgraded it to CM 11. In both cases sending sms was not working (calls and internet fine). Trying to fix it I went also in the *#*#4636#*#* testing menu and changed setting of radio. But now I cannot restore it and I always get no signal. Both with CM but also booting from Stock ROM.
I flashed many times but still nothing. As first I'd like to have singal back to call and use the net (3G). then I'll fix sms.
Can I do a sort of radio otpion reset? or firmware reset?
Plese help! Thank you!
IF there is some better section (or forum) just tell, I guess it can be a common issue and not specific for D4.

fastboot radio radio.img
I did it too
radio.img is found on the fastboot archive, no data will be lost. enter in fastboot by pressing vol up + down and power
Regards
To make your SMS work, you need to change a setting in build.prop relating to it, none of the radio settings will make it work since that isn't the problem.
ro.telephony.gsm-routes-us-smsc=1 must be changed to ro.telephony.gsm-routes-us-smsc=0
or install mentor's gsm patch
