Alright, the short of it, I flashed the wrong radio. I flashed an AT&T radio by mistake and I own a T-Mobile Nexus S. So, afterwards I realized that I no longer had 3G because of it most likely.
In a bid to try and fix it, I have tried everything I can think of. I have disabled and re-enabled data, re-flashed KB3, APN switching, check in menu with all types of settings, re-flashed customs ROMs, tried to revert to backups, and at this point I'm up to returning to stock and system updating to GRJ22. Still with no 3G data.
Is there anything I'm missing? Does anybody have any suggestions? The last option I can think of would be to get a new SIM card since my SIM is from before T-Mobile had 3G and I've heard they can have problems with 3G. I should also note that my signal has been pretty weak, not making it better than -100 db. at best most of the time.

Hello XDA,
I've been having problems with my Nexus S and I've tried everything I can think of to fix the problem but failed. Just wondering if someone would be able to help me.
Background:
I was using ICS Brainmaster's Koush version. I've been following the ICS builds since Drew Garen's SDK port. Then onto Kwiboos then I was flashing which ever ones I could get my hands on. Never a problem with installing on top after clearing cache. I had tried full wipes when I had problems but I installed v4-6 on top of the previous build.
The Problem:
So on the latest Brainmaster's build, one day I was low on battery so I turned on 2G networks only (not the first time I've done this on this rom) and proceeded with using it. When I was able to get a charger I tried to switch my 3G back on. At this point I could not get onto 3G anymore. Only edge. I tried toggling airplane mode, reboots, and playing around with the *#*#4636#*#* settings. Doesn't work.
So I gave up trying to fix my ICS rom and was thinking a full wipe would help. So I did a full wipe and installed the latest Brainmaster's rom (Koush ver). My memory fails me a little bit now but from what I remembered, on reboot I only had EDGE still. I tried Kwiboos ICS rom same thing. I tried Koush's b11 version same thing. I even tried a regular CM 7.1 rom and still no 3G.
At this point my phone isn't even connecting to EDGE anymore as well. I wasn't sure what was making it worse or what was fixing it. I even tried switching radios to the newest radio for i9020a and also reverted back to my stock radio for i9020a. I even tried the XX radios like the KD1 (the one I was on before all the problems) and the newest one as well.
In the "About Phone" section it shows that I don't have a network at all. When I try to search for networks I cannot see Rogers anymore but instead only one weird network 302490 (it stands for the Wind Carrier network).
I give up and hope that XDA has some ideas for me.
TL;DR
what I have tried
-Wiping does not help
-using different APNs (Rogers has two APNs)
-using different radios
-using different roms
-I even switched my sim card to my sister's NS and confirmed my 3G still works. I also tested my 3G on an Atrix and it works.
-restoring to an old nandroid didn't work
-playing around with the *#*#4636#*#* didn't help (like switching to GSM (auto) WCDMA etc, AND changing radio bands to USA)

isnt the KD1 radio for the 9020t not the 9020a? thats my favorite radio to use with my 9020t on tmobiles network.
there is a KD1 for all versions I'm pretty sure. I was using it for the last few weeks with no problems anyways. I switched back to the ones specific for i9020a as well but it didn't help me
Edit: The radio used from this thread: http://forum.xda-developers.com/showthread.php?t=1116884
"Radio for I9020a/I9020t/I9023
Radio JK1/Radio JK8
Radio KB1
Radio KB3
Radio KD1
Radio KF1"
No one has any idea? Simms22?
If not I think I'm going to restore, lock, and try to get a warranty from Rogers..
First make sure you have setup your gmail over wifi. Pull the sim out. Keep rebooting your phone(this can take a while) until it says no sim card at the lock screen. Pull your cover and slide your sim in while its on. The put it in airplane mode and turn airplane mode off and it should connect.
You may also want to try toggling airplane mode on and off between reboots. Sometimes the airplane won't go away when you do this until you reboot, don't worry about that. I've also had better luck getting this to work while connected to Wi-Fi.
I'd also try to minimize kernel flashing after you get it working, it usually causes total network loss again when you wipe dalvik. Putting you back at square one. Also be patient this can take a while. I'd also minimize reboots as they can force total network loss as well.
Also I've already sent my phone in for this issue and Samsung rejected the claim stating there was corrosion due to water damage. But magically all of my water indicators are still white.

So, I got a AT&T Skyrocket s2 i727 from amazon. its already unlocked and i noticed it was stuck on edge speeds when i put in my sim card. I researched why it was on google and came across this site, which i have to say is amazing!. i have read every topic there is about how to root/unroot, flash roms, radios, kernels, etc. over the last i dunno, week or so. So i decided to give it a try since everything is step by step, which im not illierate towards, i understood what it all meant. first thing i started out with is odim and flashed the cwm touch for the skyrocket, which was easy. i then researched some more and seen i wanted to make this phone on tmoblies 4g service, which here in iowa is called IWireless, anything tmoblie works with this since they are an affiliate of tmoblie. I started out downloading all the radios, which i have:
cwm-tmob-kl1-radio
Telus_SGH-T989D_Kj3_radio
Tmo_SGH-T989_KID_radio
Tmo_SGH-T879-UVLG3_radio
Tmo_SGH-T989_VK1_radio
Tmo_SGH-T989_UVLE1_radio
Blaze_4G_LB7_ICS_Radio_MOD
so as u can see ive got pretty much all of them. then i found which rom i wanted to use, i downloaded CM9 and CM10. for the CM9 build i seen the best kernel for it: InstigatorX-CM9-Kernel3-v6.0.3. also downloaded the gapps for each cm build.
then i followed the instructions the CM team left, backup, factory reset, format, install the radio, then cm os and finally the gapps.
I did all this with each radio and each cm, everything. no i did not brick my phone im alot smarter than that lol. whenever i try a radio, usually im just stuck on the edge speeds. i go into my settings on the phone and it wont save me selecting the lte/gsm/wcdma, just stays on the wcdma preferred....when i did each radio i started from fresh, cleaned everything out, even tried the davlik wipe in the advanced settings in cwmtouch.
so i read in other forums that ppl tried to flash over radios. that didnt work, i was left with no signal at all.
i still have the imei number on my phone when i dial *#06#, so i havent lost that, but every radio i use my baseband version says unknown.
also when i enter the service code in for cm10 and cm9, it wont save my selction of what bands id like to use....
so any help here would be appreciated...im losing my mind over this and it sucks...thanks for anyones help, i need it.
Edit:
switched back to stock ics from my recovery, installed the blaze radio, showed i had 4g, but had no bars. i called someone and after i called them it went back to edge. went to search for networks and all i can get is E again. under settings it shows im on edge 2....so im close but obvisously not close enough. i live in a major city here in iowa and i live a few blocks from a wireless tower...any ideas?

Flash a T-mo radio that gets you on the network, then look around and find the proper APN settings for your provider. You will have to go into the APN settings on your phone and create a new APN with those specific settings for it to work properly. I am not sure what those settings are for T-mo but you should be able to find them with the search feature.

so ive went back to the recovery, which the phone was set at before everything, flashed the radios of blaze and the uvle1 and it shows i have 4g but it bareley even runs. also each time i flash a new radio my apn settings are there, iwireless automatically downloads them to ur phone when u turn it on, and i verified the apn settings with another iwireless phone, an alcatel 995(4g phone). and now i can send a text message, the other phone receives it but the other phone doesnt receive mine. any other ideas? im going to try flahsing all the tmo radios to the phone and see what i can do. also is the radio and the modem the same thing? do i need to find a tmo modem and flash it on there and then a radio?
EDIT: nvm radio and modem same thing it seems like...lol. anyways ive tried the other radios, i completely lost signal with them as to they wont work. does anyone have any other radios that might work? i dont care if it gets 4g just at least 3g lol. im just geting tired of working on this and about to give up this really blows.

Modem and radio are same thing. Other than an APN issue I know of nothing else other than a #*number combination to enable lte settings. I am not sure what that combination is though as I live in a not-lte area and have not needed it. You may want to search the SkyJB thread as I think it was discussed at length in there. And I would try each and every one of the t-mo radios/modems as you might actually find one that works to enable 3g/4g in your particular area.
Hi Guys,
Just switched over from the Iphone and liking the Android platform so far. So in my tinkering quest, I think something got screwed up with my APN.
I flashed ViperOne 3.1 to my HTC One (T-Mobile phone, but I am using an AT&T SIM) with 4.3. Radio. 4A.21.3263.03 with the latest firmware from Tmobile (side note, Im still not sure if/how the firmware changes when flashing a new/custom ROM).
Anyway, I flashed Viperone and everything went fine and updated the new APN for ATT. With the stock phone, I had been using the "pta" APN and got great reception and LTE speeds. With the Viperone initial flash, same reception, same speeds.
Next, I realized I didn't install the Superuser stuff so I thought I had to reflash everything...which I did. On the 2nd go around, now I can't get the pta APN to work. I get cell service (same reception as before with full bars, but no data). The only way to get data and cell is use the phone APN but cell is 3G (>1mb) and 1 bar at best.
The only thing I remember doing that could have possibly screwed something up inbetween the two flashes of Viperone, is that I installed AdAway. Not sure it this would effect anything or not.
I've also tried totally wiping the phone and installing Viperone for a third time via a sideload. I have not tried going back to a completely, locked stock phone yet. Also, tried loading AndroidRevoltion but same deal. But given I am a noob, I am still a bit worried about screwing something else up flashing back to a stock locked TMobile phone.
Any ideas on how to fix the APN issues? I have tried all settings in this thread: http://forum.xda-developers.com/showthread.php?t=2172110
As well as a couple others and combos, but nada.
Anybody? Nobody?
Some more info, I took my phone down the street and messed around a bit at a local coffee shop. I was amazed when I didn't change anything and I got a whopping 46mb downspeed. Haven't really seen that in my area. Still only had 2 signal bars when everywhere else is usual 5. I am in San Diego so coverage is never an issue. Anyway, I then traveled about 10 blocks away to run an errand and it dropped back down to under 1mb. Same 1-2 bars. Something is definitely funky. The phone and data works. talking on it seems fine, just doing any network data stuff is very slow other than that one instance.
I have a verizon gs3 that is rooted, running beanstalk 4.4.251-20140301-d2lte. I can't get LTE to work correctly. I can get LTE to turn on if I change my 'preferred network type' to LTE/GSM/WCDMA, but then I have no verizon signal (voice signal). When I have it on 'global', I can get 3G and verizon signal, but never any LTE.
This has been going on for quite some time. I've switched between all of the 'preferred network types' but its always 4G and no cell signal, or 3G with cell signal. I used to be on CM 11 nightlies, thought that might be the issue. I switched to Beanstalk, but have the same issue. Just yesterday, I updated my firmware from here: http://forum.xda-developers.com/showthread.php?t=1788313
Is there something obvious that I'm missing?

I have the EXACT same issue, so you're not alone! Unfortunately, I have no answer for this either.
I was running CM11 (just the stable releases), started noticing lack of LTE a few weeks ago, decided to give SlimKat a try. The ROM is damn near flawless besides this LTE issue. I could actually never get it go into LTE mode through the normal settings, it would always fall back to 3G (and I'm in the middle of a capital city where there's plenty of 4G coverage). However, if I did that *#*#4636#*#* trick to go into testing mode, I could force it into "LTE Only", at which point the phone would be in LTE mode, and enjoy the blazing fast data speeds I pay for .... but can no longer make phone calls.
Anyone else out there experienced this or something similar? Any suggestions would be greatly appreciated.
Thanks!
After doing some research on it, I decided to flash back to stock and unroot. After that, I still could not get 4G, so I took it into the verizon store. I told him the problem, and that I had heard that it needed a new sim card. After doing some simple test, he burned a sim card for me and that did it! I'm thinking that soon after I flashed a CM11 nightly (a month ago at least) I dialed *228 to update my cell coverage. I think that might have fried it. I have limited knowledge on this topic, but I did read somewhere that dialing *228 on some custom roms is not good.
It would be nice if you could take it in to the store without flashing back to stock, but I'm not sure if they would go for that or not.

Cheers people,
I've been having some trouble since upgrading to lollipop. Since flashing the lollipop factory image, something happened to the carrier settings on my nexus 5, I keep losing reception and LTE has stopped working -- only 3g/h is still working. I've tried resetting to factory conditions, the condition persists.
One thing that I've managed to find out by googling is that I should try updating my profile and PRL -- the trouble is, none of the instructions on how to do it work for me. I'm in Croatia, on t-mobile's cheapo virtual carrier 'bonbon'. I don't have the option in 'About phone', I don't have the option under 'Carrier settings', in fact I don't have the 'Carrier settings' option under 'Cellular network settings' at all. I've even tried ##UPDATE# and it doesn't work, though that may be Sprint specific. Does anyone have an idea how I could update my profile/PRL, or how I could get back LTE, and possibly boost my cell reception, because I suspect that's part of the same problem.
I've tried rooted and unrooted, with the stock and franco kernel.
Any ideas? I'm really getting really frustrated with this
Okay, answering myself for posterity: I just flashed the kitkat factory image, LTE came back and reception improved. Then I accepted the OTA, everything seems to be working fine now. It seems that the factory image had screwed up my APN settings for whatever reason. Looks like it's sometimes better to get the OTA update than to flash the factory image.
