[Issue] Phone doesn't switch back to 3G? - Nexus S General

Several things.
Running a i9020a with KB3 radio right now. I run NSCollab and have been running it for a month. I stay on top of the updates.
I tried switching manually to 2G but if I switch back it fails. I also tried the latest Toggle 2G fix so it doesn't FC, and it does automatically switch me to 2G, but I nevver get back to 3G. I let my phone sit overnight and it failed to go back to 3G. I was on EDGE the whole time.
I flashed radio KD1 on top and it didn't bring me back. The only way I got back was by flashing KB2 and rebooting, then KB3 again and then I got 3G signal back.
Is there something with my phone or have other people seen this too?

horrible service lately

Anyone else having bad service? I currently have the latest radio, js 1.5 build. Its been going on for like a week. I'm debating on switching back to the previous radio to see if that will fix the problem. I'm also guessing maybe it has to do with the lx just being released.
My G1 is going nuts switching to Edge and GPRS back and forth for the last 2 days.
i just reflashed the latest radio, and everything seems fine again
I've had network disconnection issues with the 2.22.19.26I radio so I flashed back to the 2.22.19.23 & all has been well so far.
FYI: http://forum.xda-developers.com/showthread.php?t=515624
Although I am not 100% sure on how this works, I called T-Mobile and had them "reset my connection". Had to turn the phone off for 5 minutes and when I booted up, I have had zero issues since.
She said sometimes the phone will find a tower and get "locked" to it. If you go outside of it's range, you lose your signal. Not sure exactly what the real truth behind this is but whatever she did fixed the problems...
Running 26I
I'm using 2.22.19.26I radio on JDv1.5 and haven't had any problems. I reboot frequently, though, not sure if there's anything there.

stock to cyanogen to stock

I just unlocked the bootloader to my N1 last night. I made a nandroid backup using ahmn ra. Then wiped my phone and installed cyanogen's latest rom.
I had trouble with the radio flipping back and forth between H and 3g, so I decide to go back to my nandroid backup.
So my question is am I back to my orginal rom? It looks like it, but it has superuser permission still in the drawer?
go to settings and about phone. it will tell you what build you are on.
also, what is wrong with switching from H to 3G... those are the signals that most people want...
it says build ERE27. How do I tell if it's rooted?
The radio complaint, when you go to your email or market, it's like it gets confused, gives up, and throws up a network error. You hit retry it works. It happens 1 out 3 times but it gets annoying.
with the ere27 recovery it stays stable. I thought about flashing another radio but I didn't think that was a good idea, seeing I don't even know when my N1 is back to factory default.
I think your phone was always switching between H and 3G, you just didn't know it because at stock you get the '3G' icon for both UTMS and HSPDA. Cyanogen's rom just changes the icon when you move up to HSPDA.
LOL you pleb This is the reason the phone doesn't have an HSDPA icon as standard... it's meant to switch! Your network switches you over to it when you need it and leaves you on 3G when you don't.
Well good grannies! It does explain why the H kicks in for the data..
hopefully this thread will help the next noob that comes along. Thanks

3G stops switching back after wifi?

This is a strange one. I have been using Fresh Evo 3.2.0.0 rom for almost a month and it works great. I wanted to try another rom so I tried the VirusRom... it was good but I liked Fresh better. So reflashed my Nandroid image and all was well.
But then I started seeing a lot of failed connections to the market and noticed that my 3G was not connecting. I live in Chicago so I am fully covered by 3G in this area, and even 4G in many spots. Usually when I leave a wifi area, the phone switches back to 3G almost instantly. But ever since nandroiding back to the Fresh Evo 3.2.0.0 rom, it only works after a reboot. As soon as I hit a wifi zone and then lose it, 3G doesn't switch back on.
4G and Wifi both work, but if I disable both wifi and 4g.. 3g doesn't come back without a reboot.
I've even switched off the Mobile network using the widget and the power button menu.. no luck. Only a reboot brings it back.
So then I even did the trick to get my PRI up to 1.40 and that worked fine. But no change in the behavior of 3G. When I reboot and 3G is working, it works great as usual. Just not sure why the switching no longer works. I even tried switching back to the rooted sprint stock rom.. same deal.
Anyone else having any issues?

yes, I have noticed this at times. Just happened to me. Failed connection when switching off 4g to 3g. Using fresh 3.2. But I noticed this as well on other roms. I had to reboot each time to get 3g working again. I also reset my data connection last night but it obviously didnt work.
I've been having issues with my 3G for the past two days. Similar story, I did and Nand restore and that is when it started.
I am getting an error code 67 everytime I switch from Wifi, 4G or even when I reboot to try and fix this. Usually if I let it sit it will come back, but the error message popping up is quite annoying.
Wish I had something more helpful to say, but I can just add that I'm having the same problems switching from wifi to 3g. Even after 3g turns on it will sometimes turn off again randomly and I will have no connection. I'm also running fresh. In addition my 3g signals are quite week. kinda a mess...
Weird. My phone did this today for the first time. The thing is, I've been on Fresh 3.2 for a month now, and I flashed the latest Baked Snack rom yesterday to test it out. It never did it while I was on Fresh, but today after turning off WiFi, it wouldn't connect to 3G for anything. No text or data transfer at all. After I rebooted it, it started working again, but my phone never did this while I was on Fresh.
I am having the same problem and I am using Fresh 3.2 as well. I did go to a different rom but then went back to Fresh's rom and that is when it starting happening to me. It will only pick up 3g now and then and even when it does my speed is super slow. Hoping someone comes up with a fix as I made my own post but no one seems to feel the need to reply to it.
Theories...
Same here. I'm on Baked Snack 1.7x
I know Fresh and Hero both use some of the same components. I flashed to Cyano and have had no problems with the 3G radio. It's very snappy switching on and off after wifi connects and disconnects.
I do know there have been one or two issues with the radio with people who are on the 3.28.651.x roms. (for instance, if you enable 4G then disable, sometimes it randomly turns off and on without you knowing until you restart)
So my guess is maybe the 3.28.651.x series is glitchy. You guys want to try going back to 3.26.651.6 and do some testing?
happened to me on stock. Had to reboot the phone to fix it.
This seems to be working for me today with no problems so far. I am wondering if a tower was down with Sprint putting up the 4g around my city. Will keep posted if it happens again but seems to be running like normal now.
This has to be network issues maybe the latest PRL.
Mine has did the same last couple days also on power on , it takes longer for 3G icon to kick in.
Signal flux has been occurring more then norm fast download - Upload speeds taking hit some parts of the day.

I am on 3.26.651.6 build and this was happening. I am no longer having any problems with this. I do feel this might have been a problem Sprint's servers were having. Seems like everyone started having the problem right around the same time.
It must be... Going to an older PRL didn't help, and there are a bunch of forum topics being created about this on other forums as well. Guess it's time to play the waiting game.
My issue is so bad right now even if I restart my phone, it doesn't even get data connection right away. 10 minutes waiting now and error code 67's keep popping up.
This just happened to me today. It took me awhile to connect the error statement to the fact the 3g didn't turn on after I turned off wifi. But I was able to press the 'data connection' button on the switchpro widget to turn 3g back on.

That is how I got it working a little bit last evening but as I said in my last statement it is finally working and has been all day. Not sure what the deal actually was as I did not change anything since 2 evenings ago. I am thinking that Sprint is doing something which is messing everyone up at one point or another.

3G issues

If this is a repeat thread, I apologize but I'm not having any luck finding this specific issue.
Since using EB01 I've noticed my signal bars going frequently from 2-3 bars down to 1-0 bars, yet checking the signal strength in the About Phone>Status section it is consistently in the -80s, which is relatively good signal.
After a while I started noticing that if my 3G icon was showing up and/or down activity, it would show only 1 or 0 bars, yet when it switched to "D" (meaning dormant), it would shoot back up to 2-3 bars, until data started flowing again then it would go back to 0-1 bars.
As I started troubleshooting this, I was using the Speedtest.net app to check my download speeds. When data was showing that low, it would either time out or would give very low speeds (in the 100k's both up & down). Sometimes it would go up to the 200-300k's.
Now here's what I don't understand: if I turn off my data connection, then turn it back on, my data connection goes back up to 2-3 bars again, and download tests go back to the 600k-1mbps speeds again. So it's like it's losing data reception until a fresh connection is made.
I've tried both some of the Superclean ROMs including the latest 2.8. I've been using the EB01 voodoo kernel. I also recall when I was running the EA28 OTA update before rooting that it was happening as well. Right now I'm back to the stock debloated deodexed ROM with the same voodoo kernel and switched to the DL09 baseband radio and had this happen.
Has anyone else run into this problem? Does anyone recommend a certain ROM/kernel/baseband combination to see if it will help?
Any help is appreciated. Thanks.

You know, I never really paid it too much mind, but I MIGHT have a similar situation. Though, I don't have to reset the connection, it just up and down drastically a lot. I will look into this myself, see if I can find anything to help you.
Yup. I had this problem too. I had a phone that initially came with DH rom. After I flashed EB01 modem and rom, I was missing 3G for 30 seconds after I wake the phone up. Practically the same symptoms: bad battery life, low up/down 3G speeds (I had ~100Kb/s max). I tried to flash different modems DI, DJ, DL, EB, tried different non-voodoo kernels, different roms, nothing helped. Even ODIN back to full stock DI01 did not solve the problem.
Solved with getting a replacement phone. After I got a replacement with EA28, I got double battery life and great up/down speeds. So right now I am wondering: should I risk my phone to flash leaked EB01 again?

Radio Issue Needs To Be addressed

On the latest radio 4.12 I noticed that the signal drops every minute for about 10-20 seconds. I have good reception in my area, normally 4-5 bars. The only work around I have is dialing *#*#4636#*#* changing to GSM only. BUT, when I reboot it goes back to default WCDMA only, I'm on bulletproof miui, latest pershoot, latest radio and yes, I've tried data EFS wipe and v6 and v3 of automatcher. Please help!!!
soooo.... go back to your previous radio that worked for you?
Been running this radio since it was posted. I have lost complete signal twice, only need a hot reboot to regain signal. Aside from that, I have noticed better reception in areas where I had poor signal before.
