No Network - Nexus S Q&A, Help & Troubleshooting

Hi,
I week ago I completed wiped my Nexus S 9020T and installed CM9 successfully. It smooth but loses network quite occasionally and the only solution is to reboot the phone.
I checked the baseband: I9020XXKI1 —*is it okay for my model 9020T?
I'd really appreciate any help.
Thanks.

I'm actually still on jk8, and like u and few more i have data drops.
Not sure if this has anything to do with radio or nexus s in particular, since i had few Androids and all of them suffered from occasional data drops (i was always with one provider, o2.UK )
To me it seems like there is data drops and phone for some reason is not able to reconnect.
There is few threads regarding this matter, so u can do small research on ur own.

Oh, is there another bootloader or kernel i should use? Matrix kernel? would that help?

Kernels probably will not help, try different radios and ROM combos.
Xxx oops! accidentally beamed from my awesome NEXUS S! xxX

I see, can you please suggest any Radios, I'm a complete noob at this. I know how to flash but thats it.
As for ROM, I quite like CM9 and don't want to change.

[Radio][28th November 2010] 2.42.02.10.29 Sprint CDMA Hero

Ok, so for those of you who are wondering where to find the new Sprint CDMA HTC Hero radio, here it is This is for Sprint users on any rom; however if you're using Firerat's, it will not be as simple as flashing the radio. For those of you running Firerat's, either follow these instructions to flash the radio or see this thread. For those of you NOT running Firerat's, here are the steps to flash:
Download the radio and place on the root of your sd card
Choose "install zip from sd card" in recovery
Select the radio
It should flash, and then ask you to reboot the phone via the menu.
Select "reboot phone" from the recovery menu
The phone should reboot, with a big box and android showing
The phone will then go back to recovey, and say "Formating Cache..."
Wait about 5 seconds, and then reboot!
You're done then, new radio should be flashed! Let me know if you need anything or want to express thanks!
Thanks to Nfinite for the radio pull, here's the MD5 for it: F15CF77B1C08CFB1F357E2574F386F5F
Thanks for this. I revamped my HBOOT thread and included a link to here to encourage people to use this method whenever possible.

You both are so awesome, thank you!
Did not seem to impact signal so far, though I've only tried laying here in bed. I'll report back after work Monday, as that is always the major radio killer spot for me.
Side note: could be a placebo, but data does ' seem' snappier. I'll report back Monday and hopefully have more answers.
At least as good, if not better so THANKS!!!

No noticeable difference as of yet, but we'll see once I get home how it fares.
Since I use firerats and that method seems daunting, any potential issues with just staying with the old radio? I am due a new phone in Feb and just thinking it might be 'easier' to just stick with the old...also, does anyone know if the PRL is still 60671 or has that been updated also?
Will this work on various software build versions of the stock (rooted) Sprint Hero? Just asking because I didn't upgrade to the latest OTA so I'm still running 2.31.651.7.

Yes it will work.It won't change from custom rom to custom rom.Only if you flash a different radio or if your service provider changes it in a update.(Impaler or anybody if I'm wrong please feel free to correct me.)

That's a rom issue, not a radio issue. I'd flash deca's 691 capped CFS kernel; that should fix it

if you ran my rom with no issues then you flashed this winzipped radio and have issues now that most likely is not a problem caused by the rom

Could be kernel speed, seeing as if the radio was messed up there'd be more serious issues
Didn't mean to start a fight here fellas. but all I did was reflash my ROM and its working great. I get better signal in my house now. Thanks

No signal while using CM7

Having a major problem. I just installed CM7 but did not get a working signal, just got "searching for service". Before installing I was using a Sense ROM and it was working 100%- but I do remember switching off LTE when I was on the ROM and I never changed it back to on.
So anyway, I also flashed a radio via hboot and same thing.
Is there a certain radio I should be flashing?
When I go to settings I just get Unknown for the baseband version. Is this normal..? Should I have done something that maybe I missed?
let me know, right now I'm without a signal.. so no texts or phone calls.. pretty bad
Which version of CM7 are you on? If you are on RC1.3 then you need an MR2 radio. I'd suggest the radio from the OTA located HERE.
Yes the latest RC1.3
Okay thanks I will try this out, things are REALLY jumbled here.. I've checked out like 4 different radio threads.
Will let you know if it works

Yeah now that you are on this radio you can flash the vast majority of ROMs and ALL GB ROMs for the TBolt without changing the radio.
Also pay no attention to the idiot cussing you out for asking a question in the CM7 thread.
Thanks man, works great.
No problem! Glad you got it up and running!!
Is there any advantage to putting the MR2 radio above on a stock rooted TB?

I would use it solely because that's the radio that VzW tested and I would think it works best hence why they released it.

Can you break your device from "over-flashing"?

I'll be the first to admit it - I'm a flash-whore... some days I'll flash 2-3 ROMS, then try various kernels, then restore my nandroid when I'm done for the day.
Some weeks I flash ROMs daily, some I flash a couple of times.
Can I damage my device if I keep this up?
I think there's some theoretical limit to the number of r/w cycles on this kind of memory, but I've never heard of anyone who's actually exceeded that limit.
..
Good. That set my mind at ease.
Thanks for both the question and the answer. Never knew how to ask the question....puts me at ease too!!!

ive flashed my ns thousands of times, roms and kernels, and im still flashing..
thanks for the info!
great question
I have been flashing roms like a madman too. I guess I flash more kernels everyday. At the moment, I don;t think that this will happen, but in the long run , yes.. there might be some problems. Perhaps you should slow down when flashing a rom. This might give the rom a few days to get back to normal before you do a full wipe again.

Your statement makes no sense. Allowing a few days for the "rom to get back to normal" has nothing to do with flashing.

With respect to flashing.. As others stated, there's a theoretical limit of writes as with any flash memory, but I've yet to seen it reached. As for a rom settling in..it's settled in a few minutes after a reboot from the first boot.
Sent from my Nexus S using Tapatalk
I understand as I am also a flash whore but I think we would have to be some super flash ho's before our phones breaks. In other words I may have been flashing at least 3 times a day, but you gotta flash much over what anybody would want like hundreds of times. Also if your looking for a good ROM look at my signature, it doesn't disappoint.

working on my forth year of flashing.. g1, og droid, nexus one, and nexus s. probably 5000+ flashes between them, not a single time did i have issues with the imei or a corrupted efs folder. truthfully, the og droid was only a wifi device for me since im on tmobile not verizon, so we wont count it.

Connection problems with SUPERLITE CM10 JB4.1.2 RoM

I recently flashed to Vincom's SUPERLITE CM10 JB4.1.2 RoM | V8.0.
Ive gotten things up and running pretty well, but there is one major issue I seem to be having. My phone is not consistently able to connect to data on AT&T. I am frequently losing my data connections in locations where I have always had them in the past.
I searched around on his developer thread but didnt see an answer. I saw a reference to APNs for AT&T, but his note says these should now be included in the ROM I flashed, so Im not sure if I am missing something.
Anyone know if this is a common problem or how I can troubleshoot it and get up and running again?
Thanks.
Haven't heard of this being a problem. What modem (baseband) are you on? You can find it in settins, about phone.
Also, in settings wireless, more, mobile networks, Check that the access point name is on att LTE

Its gotten worse. Ive spent the last 5 hours with almost zero data access.
I see baseband version i727UCLI3.
Access Point name was was set to ATT wap,cingular. I switched it to ATT LTE (pta)...should this fix it? Any idea why this would have happened? Will I need to keep checking this or was it just something from the ROM flash?
flash the ucli3 radio again or try another ics radio
which recovery are you on

I am using TWRP for recovery if that is what you mean?
I will search around for how to locate and flash a radio...does it matter which I use or any ICS radio should be OK?
Read vincom's stickies in the development forum. You'll find everything you need there.

reflashing radio is the simplest things todo on our phones, no harm will come of it and sometimes beneficial as cwm/twrp wiping and flashing roms dont touch that parition

Vipers ROM and data speed

I'm new to this rooting business and after a slow start I managed to Root and flash my first ROM at the weekend. I used Vipers 1.6.3 which, after some research, I gather is a pretty old version. I'm still impressed though even if it is some of their older work but the one issue I've been having is with my mobile data speed. I haven't been getting anything above E/G speed wise and I've found it quite frustrating. I'm gonig to update to version 3.1.4. when I get back home but do you think this will resolve the issue? Is there a setting or something that I need to be aware of that controls maximum data speed.
Sorry if this is a complete noob question but I'm doing my best with searches and guides but I'm not finding anything particulary helpful.

OK would the latest radio's not have been included inthe zip files then?
I was going to download the rom from this thread..
http://forum.xda-developers.com/showthread.php?t=2216858
I can't see any information about radio's in there. It does mention about ICS non compatible kernals. This is confusing me further. How do I know what kernal I'm currently on. Once again.....sorry for the noobness but after the drama I've had just getting this far I'm nervous about messing it up.

Hey,
Did you try a full wipe so you know for sure it's not the problem of the rom, just make a nandroid backup in your recovery(4ext recovery is higly recommended)
Also another trick,
As you know the back of the sensation is also the antenna...
You can try to gently clean the gold spots.
About the radio take a look at here it says when you have the wrong radio it can cause bad reception so it can be the problem.!

try preferring cdma in quick settings
For me that did the trick, but now that i updated to 3.1.4 this option seems to be missing, so maybe obsolete and handled automatically as i have no issues without it.
