i9020A (ATT) completely lost 3G on all ROMs, help! - Nexus S Q&A, Help & Troubleshooting

I've completely lost 3G ability on my NS, and I'm not sure what happened.
Here's my order of tweaks:
CM7 nightly (with 3G)
MIUI (with 3G)
ICS rom from SDK (no more 3G!)
ICS from kwiboo (no 3G)
ICS from koush (no 3G)
CM7 stable (no 3G)
I guess sometime during my playtime with the ICS from SDK build, something messed something up and subsequently I cannot get 3G anymore, regardless of ROM.
I'm not sure where even to begin troubleshooting.
- Yes, "use only 2G networks" is unchecked
- My APN should be correct, as they are the ones that loaded automatically from the ROMs. That has always worked before
Anyone have any ideas? I'm desperate for help. I haven't had 3G for what feels like a month!

Here http://forum.xda-developers.com/showthread.php?p=19424857 in this post there is a link to the radios try flashing one of those to see if that fixes things. If not try flashing a stock unrooted rom and start over

You know what? A new radio worked! I don't know why I didn't think of it before. Seems so easy in hindsight.
This brings up another interesting thing. Seems like a lot of the radios that used to give me 3g don't give it to me anymore, including the most popular ones people are using. That's weird...
edit: Actually, no radio issues anymore. My old radio gets 3g again, as well as others. I just needed to rotate the radio versions a few times and reboot a few more times and it fixed itself. Totally weird, but no more problems!

I had the same issue on AT&T 2 nights ago. It turned out that it was an AT&T network issue which was confirmed by tech. support.

Advice sought... my VIII is now GSM only

hi -
the problems: since flashing 2 weeks ago my vario III only works for voice and data in gsm only mode - with 3G enabled i generally can't make or receive a call or connect to data, but the device . Everything works when i switch to GSM only...
The complications/wierdness: straight after flashing a new rom or radio i have sometimes been able to get the device to connect to 3G or make a call - but this usually only last for one session or so.
What i've done: i've installed just about every combination of ROM and Radio i can find - including all of the 6.1 radios with Dutty's 6.1, the "official" vodafone 6.1 rom, alex's, schaps, and i've tried going back to 6.0 roms and the 1.27.12.32 and .11 radios but still the same
what is the verdict? bricked? or am i missing something....

I don't think it's bricked.. if it was bricked your device wouldn't even turn on.
Did you hard reset after each flash?
Was it working before your original flash?
answers to both: yes
- working fine before i flashed it
- I've been obeying Dutty's rebooting advice - how could I ignore instruction given in bold AND capitals?
I'm having the same problems. Thinking of putting origional ROM with radio back on and removing hardspl and returning under warrenty but cant find origional splash screen anywhere! Help would be appreciated
had the same problem with my tilt...changed sim card ...different roms ...radios ...basically everthing i could do....but in the end called at&t and they sent me a replacement...goodluck
I had a similiar situation but with my GPS.
The Tilt I bought just 1 month ago was a GPS Champ, always acquired a lock quick. I had flashed XDA-Live v1.5 right over the at&t 1.62 Rom (after HardSPL of course).
Then I used th enew SIM/CID Unlocker (with the hacked Polaris Radio) and of course flashed back to the at&t Radio (from the leaked at&t 1.60 Rom).
Since then I had a coupel of times where the GPS locked-up and required a soft reset.
So yesterday I flashed a WM6.1 Rom and a Niki Radio as I've seen a lot of user report excellent results.
It made my GPS useless. I quickly reflashed XDA Live v1.5 (with the Radio from the at&t 1.60 Rom) but my GPS still seemed lost.
Ironically today is day #29 of the 30 on this Tilt so last night I removed HardSPL and flashed the Official at&t 1.62 Released Rom using the Official exe and everything figuring I'd returnt he unit today.
Wouldn't you know it, I tested the GPS and even on the untouched at&t Rom it was working better than it had ever worked before!
Now I know that the Radio in at&t 1.60, 1.61 & 1.62 are *supposed* to be the exact same but I can say that the over from at&t 1.62 fixed a problem that the 1.60 Rom's radio couldn't. Yes, I do a hard reset after each flash already.
Heck when my daughters return from Disney I'm going to flash the 1.62 version fo the at&t Radio onto my oldest's Kaiser and see if it improved her GPS also.
seems like everyone who replied has a tilt not a VIII. Are you sure your settings are correct for your network? that would be my first guess at this point input them manually and dont use the connection wizard app as sometimes it doesnt work right. also check your phone settings make sure its set to AUTO or UTMS only if all else falls force it into 3G mode using the Band settings post your results back please

hey I am having a similar problem at my house when i first got my tilt i have a very strong 3G signal here. That tilt messed up sent it in and this new one that i got worked just fine till i flashed a new rom on it now it wont pick up 3G unless i go somewhere else and come back to my apt. And yes i HardSPL'ed it and hard reset after flashing. I even went back to stock tilt rom and that didn't work. I have tried all the radio's on this forum from stock to the new imported NIKI radio's nothing has brought it back. When I go get the 3G signal elsewhere and comeback god forbid i have to soft reset because there goes 3G out the window and locked to edge. Should i return to AT&T for an exchange or is there a fix i'm not finding?

The Tilt Roms by default don't allow manual band selection.
Bad Data settings wouldn't cause poor reception just inability to connect (regardless of 3G or Edge/Gprs) for data sessions.
Based on my experience I would say first test is to do the work and reset your phone to the latest shipped Carrier Rom for your Carrier and see if your problems persist.
When I was having my GPS issues I also had a few wierd Call issues like calls not disconnecting (I had to toggle the phone radio to actually end the call).

I had the same issue with a t-mobile(UK) viii. The issue appeared after a while using the phone before I'd got into flashing different ROMS. In the end, i had the unit swapped out and the problems went away and have not returned. You can assume its a hardware issue. I went through the is it your SIM, is it this... is it that... after explaining that basically i was right next to a 3G transceiver in a big city.
Like I mentioned, this was a fault which developed after two months of no issues.
Old hardware version (looking under battery cover):
DATE:061107(TB02)/EU
New phone:
date:090807(RB01)/EU
I have had the same issue. I have returned the phone today and exchanged on my insurance. the new phone works fine.
thanks for all the feedback - shame there isn't a fix ..
austinsnyc: thanks for your help...
- i was using the connection wizard (difference i've noticed was that it includes a proxy server which i don't when i set up manually) so i created a new connection manually
- i've changed to 3G-only and i got "no service" (though i have previously got it to work)
- i put it on auto, it registered 2G then showed 3G signal in the taskbar. Tried to connect to my manually created connection - no joy: "cannot connect for an unknown reason etc".... then i got "no signal" for about 30 seconds, then full bars of gsm, then shows 3G again....
changed back to gsm only - works fine.
I'm not exactly sure t-mobile are going to take it back!... i'll have to hunt down the original t-mobile uk rom first....
got my new tilt in yesterday and it works totally fine like i thought in my apt. If you could wilbur i would definitely get a new one i think its the phone itself.
lol so i checked to see if switching off the 3g on my new kaiser then switching back would cause the same problem and it sure did so now im stuck with edge in my damn apt. again. I wonder if these new kaiser's they're shipping out are different than the old ones, when i first bought mine at launch oct.5, 07 i could switch back and forth between 3g. Now with 3 new tilts i have gotten i cant do it anymore this blows Damn i should have never given that first one away damn
so annoying...
i upgraded to the latest Dutty Rom (the 6.1 hybrid) - sure enough, straight away after flashing i was able to use 3G to make and receive calls, and to make a data call (but it was really slow)... then, within 30 minutes, i was back to the old phone: cannot connect a 3G call and no connection to data... so annoying - i'd almost prefer it didn't work at all than tempt me with the prospect that one day i'll find a rom that works...
anyway - I'm going to need to replace it - anyone know which rom/radio combo i'd need to flash to convince the guys at T-Mobile to take my VIII back? and btw - does anyone have any experience of trying to return handsets covered in scratches?
can anyone tell me if these problems are linked to Flashing ROMS? Since i had my last Vario 3 replaced ive been apprehensive about flashing if this is what broke the last one but i really want to flash it again.

[Q] Radio messing up after ROM upgrade?

Yesterday I finally received my Inspire. When I bought it it was reported to be unlocked, but I found out it was also rooted and radio S-OFF.
As my carrier recently released a new 4G GSM network alog with their veteran 3G CDMA network, I went migrate my account to a SIM card with my line and put it in the phone. Everything worked fine, HSDPA speeds OK, HSUPA slow (no fix yet on the phone).
Then I decided to install LeeDroid on it, the ROM is awesome, but somehow it wouldn't connect to the carrier anymore (that means, no voice, no data, some eventual GPRS connections). I restored my nand backup but it was still the same.
In the evening, I decided to flash another radio (12.54.60.2SU_26.09.04.11_M2) instead of the AT&T stock version. For this to be a fast process I had to ENG S-OFF (didn't want to mess with other methods).
Immediately the phone found strong, stable signal. I reinstalled LeeDroid and now it works as a charm, HSUPA is even faster than HSDPA (probably due to network traffic) and I'm very pleased.
My big question is: I have had many Android phones (and many Windows Mobile HTC) and I never have seen a ROM messing up with the radio, I don't even believe it's possible. So, what happened?
My only explanation is that the Ebay seller I bought the phone from messed up with something and managed to get the phone working and then sold it before it failed again.
Any thoughts about this?
What you've been through isn't normal, so something must have been messed up with your phone. You never know what a phone off of eBay has been through. Maybe it hadn't been rooted properly or something else was done incorrectly. Normally, any custom Inspire ROM works with any version of Inspire/DesireHD radio. Some radio versions work better than others, but I've never seen an instance of what happened to you with your first LeeDroid install where the data/voice connection was totally dead. What version of radio did your phone come with? It should of been either 26.06.06.30 or 26.06.04.06 - if it came with anything else then the radio had been messed with.
The good news is now that everything is working, you should be free to flash whatever ROM you want with no worry of that weird connection problem happening again. Flashing ROMs on the Inspire (except for the RUU's) doesn't mess with the radio at all, it is a separate deal. But if you continue having weird problems, I suggest flashing the rooted stock RUU from this thread and starting fresh from there.
OK, thank you.
It came with 26.06.06.30, and it's really weird, I have never had this kind of issues.
I'm really not new to android (have had a few CDMA Android phones) and now I'm switching to GSM, but I was really confident that apart from the unbranding process both phones should behave really similar.
Will see how it evolves, for now I'm really enjoying 4G speeds.
Yep, you should be fine. HenryBravo is giving good info. Some radio\ROM combinations work better than others. Depends on the ROM. That's why some chefs have a recomended radio and others do not. Good luck with your new phone.

[Q] [i9020A] Install I9020AUCKD1 baseband??

I decided to root my i9020a cuz I wanted to try the goodies. So I installed the CM7, but didn't quite like it, so then I decided to install this rom that is a kinda inbetween the stock and the CM7, but all of a sudden it died on me after a reboot I did after several days using the rom without problems.
So, I decided to install the stock rom from here and so I did. Ever since my phone doesn't connect to the 3G network and I checked with my carrier and I didn't go over my limit or anything, so I'm thinking maybe I screwed up the baseband or something.
So I tried this, but that didn't work. Tried directly doing to 2.3.4 and also first to 2.3.3. and then updating, still no 3G.
Currently my baseband reads: NO DGSXXKB3, but I remember that when I got my phone it used to read: I9020AUCKD1
How can I get back to I9020AUCKD1? Any ideas? Am I way off and it's not the baseband? Help? I'm really desperate now after hours of lurking around google and here
For 3G I need HSDPA 850 / 1900. I'm aware the phone supports 2100, but my country doesn't.
Thanks in advance

Dude - you are a life saver!!
I don't know why, but this morning I woke up with no cell reception - no phone calls, no data - on a day my son was sick and I had to call his school - I have no landline! lol. All it would say is "Rogers" in the available networks.
Got it figured out though, wiped the thing, stock 2.3.4 image, then with the settings you had above, bam, worked like a charm. Back on koodo.
Phew! Thanks again

[Q] Help! Unable to acquire network signal. Tried everything!

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.

Losing, Lost 4G

This started on the eternity rom, then I switched back to CM7 by thundershed 1.4, then 1.5 and tried various radios on all roms. 4G signal will not stay and once it is lost it will not come back even after switching radios. I have checked the network mode settings. I am leaning toward believing this is hardware related or network related as those are thoe only variables I cannot experiment with. This is happening in Utah.
EDIT: installed stock .9 rom and still no 4G.
having the same issue except it happens in 2g/3g also...
Anyone have any idea cause this is annoying... rebooting the phone temporarily fixes it for me.
