HELP! No signal/mobile internet - Nexus S Q&A, Help & Troubleshooting

If anyone can help me and get this working, I will send you $5 via paypal.
Okay so I have fairly decent knowledge of roms/kernels/flashing etc. but I just don't know what to do to fix this problem.
It seems to have happened after I've;
Used the app - Network Speed Booster
Flashed a new rom
Changed the APN (Worked fine)
What I've Tried
- Flashing a new ROM
- Reflashing current ROM
- Flashing a different kernel
- Changing the radio band
- Resetting the APN to default
- A different SIM
Baseband - I9020XXJK8
Thanks to anyone who helps! If you tell me how to get it working, I will PM you saying that I will send you 5$ paypal.

Is the IMEI on the back of your phone (behind battery) the same as the one it shows you in settings -> about?

i had same issues

Thanks for the reply, I will try that rom and kernel now and will post results later.

why don't you just use the stock rom without any changes???!!! i haven't encountred issues since the 4.0.4 is out..

In this case i wouldn't bother with custom ROMs. Grab yourself a stock ROM from the sticky, do your backups and wipes (data/factory reset, format /system, format /boot) and then flash the FULL ROM from the sticky.
This will require you to reroot. I would throw the latest superuser.zip on your sdcard and flash that immediately after flashing your new ROM to make it easier for you.

Can you try a stock rom?
Here's a list.

When troubleshooting something like this, stock is by far the best option. He is free to do what he wants after the problem and cause are found and fixed.

Hi,
What version did you install?
3.6.8 or 4.1.8?
Did you do a MD5 checksum?
Did you super wipe?
Did you add any mods?
If you want help,you need to post more information...
Hi i had the same sort of problem with my ARHD but I find out that the faux kernel was causing for difficulties.
Installed a stock kernel and all problems solved.
Still respect all developers
did a the super wipe, did a md5 checksum, and didnt do any mods, and it arhd 3.6.8

Hi,
It does sound like a kernel problem.
Try the kernel in my signature.
Absolutely no problems there.
ill try the stock kernel thanks to all
phone:htc senation
So I've tried the stock kernel I even tried flashing arhd 3 times as I read that sometimes on the third try everything works right but no luck so if I can't get it working properly I'm going to try another Rom but I was thinking could the problem be daemon controller...any digestions would be very appreciated

Recently flashed arhd 3.6.8 and I am having similar problems. More often than not, i will lose responsiveness with the touchscreen and have to pull battery. Also my phone randomly reboots and restarts. Can someone tell me how to fix this???

try flashing the kernel in my sig, this sounds like a kernel problem. theres a new ARHD 3.6.9 but the kernel in my sig is newer than the included kernel, hopefully this should fix it for u..
I sold a Sensation ebay with this same rom, and the buyer is reporting the exact same issuse you are having. I think there might be something going on here.
Up the minimum sleep clock speed to 384000 or 432000. the cpu is too idle to react properly and this should fix it. I had the same issues with Faux & Bricked kernels until I did this. No problems at all now.

Hi, i've been running the 3.6.x Roms for a while now and think they're great, but was getting interested in the sense 3.5 stuff. What in particular do you like about the 4.1.x roms? Just seeing if it's worth the full wipe effort .
Thanks

Lol yes, you are not the first to tell me that, and believe me lesson learned. Though I did mention that it was rooted and that it would be running this Rom. But yes now I am troubleshooting the phone with this person and I may have to give them a refund because they opened a case with eBay.

Daemon Controller comes with Revolution HD roms.
Run the app and you can see the options for setting the clock speed of your CPU while active and idle.
If you do flash a new Kernel you should generally be OK without a wipe/factory reset, though make sure you do a NAND backup via clockworkmod first.
Flashing the Kernel works in exactly the same way as flashing a Rom, via clockworkmod (or whatever recovery tool you use - EXT4?) - Download the new kernel to your SD card and install from there.
If you get the latest version of the ROM it will have the latest Faux Kernel in anyway, so maybe it's worth trying that? - again you should have no need to wipe/factory reset unless your moving from 3.6.x to 4.1.x Roms (different base android versions 2.3.4 vs 2.3.5)
Like I say, I used to suffer from the same issues with the screen not responding to wakeup but since I upped the clock speed for idle (and recent updates do this by default now) It hasn't happened since

[Q] WIFI isn't working with ICS

I9020, ICS 4.0.3, stocked at "truning wifi on"
dmesg suggests
Set ISCAN for wl_iw_combined_scan_set failed with -22
any idea?
what's the f*ckin problem with wifi and sim that someone have ??!!!!
for someone this prob exists with all ics roms except Kang and NexusBeam .
for those come and post "it works" : this's for some NS users maybe not you
i had no problem using WiFi in stock ICS 4.0.3
or CM9 Alpha13
maybe you just need to wipe, and flash the ROM again from a clean state
i know you want to help but you think we dont know what's doing wipe or system-boot formatting ?!

Hello,
thanks for the answer, will you define clean state?
since i have erase sdcard, cache and userdata and everything, update was from stock 2.6.3.
funniest thing, wifi tethering works
it certainly has something to do with country code, after flashing without simcard everything is working.
is it MCC that i need to change? anyone know a reliable way for this to work with simcard? (guess we need something like market enabler)

[Q] After upgrade to ISC, have no more service.

Phone info:
Nexus S GT-i9020A
carrier:Fido
location:Canada
I was using the formels MIU os and everything was fine. I flashed Brainmaster's Stock ICS 4.0.3 and then lost signal. I can't search for networks nothing. I even tried installing the radio that corresponds to my phone, which I assume is UCKF1. I have gone back to MIU and STILL have no signal.
I've tried *#*#4636#*#* and selecting the band to USA.
When flashing other roms and kernels, this never happened to me. Any help please? Been trying to fix this since yesterday and now luck D'x
Probably the wrong radio. Download the full stock 2.3.6 for your device and flash only the radio from there.
I am actually haveing the same issue, seems to be efs is currupted...

You mean restoring from nandroid backup? That won't do the trick because CWM backup doesn't include radio. You have to use the full OTA package for your phone model.

[Q] Return to Stock for Nexus S

Hello there.
I would like to ask for your good help restoring my Nexus S. I'm actually really exhausted looking for answers and tried downloading programs (e.g. One Click Stock) already. I wouldn't try to poke you guys if I hadn't reached dead end. Painstakingly exhausted for the last 3 days plus the slow connection we have here.
Using One Click Stock by Michael Peerman, I'm stuck without a signal since it says that I'm on Sprint. Everything works except that I'm always without signal.
My phone is under Globe Telecommunications Philippines. Build Number GRJ22. Currently it is in Gingerbread 2.3.4.
I won't bother rooting it again. I just want a simple droid without the extra benefits of a rooted phone.
Any help pointing me to the right direction would be really appreciated.
just flash a stock rom! and that would make a stock nexus s! and if you want even more you can lock the bootloader again!! and about the signal try flashing another radio!

http://www.clockworkmod.com/rommana...s&name=Stock Images&deviceName=Google Nexus S
Hello There.
Thanks for the hot tip. I got it all back to stock.
I did was root the phone again,
installed ClockworkMod. > Mount USB to PC > on the clockworkmod folder I created new folder "backup". Then paste the Stock Rom.
Reboot to Recovery then install from zip.
Voila! It worked.
Very much thanks to everyone.
Stock is different baseband version
I had recently flashed an ICS rom and could not get my mobile data working after trying every single radio for my model I9020A.
So I used rom manger to download 2.3.3 stock GB as described in this thread. Now it is showing I have baseband version I9020XXXB1 and when I go to system updates it says my system is up to date. How do I update to newest version of GB and show the correct baseband version of my phone?

[Q] No service, tried everything

I got a p500h from my friend since my razr droid died and I needed something to hold me over until I can save up for the note3. It had 2.2 on it so I flashed CM 10.1 for 4.2.2. When I put my sim card in I had no service.
I checked the baseband and it was unknown so I flashed it for v.20 and it appeared but I still get no service.
I don't have gapps installed because I don't really need it.
And that's pretty much it. I can't think of anything else to try, can someone help? I'm using a non-smart phone in the meantime and it is quite terrible.
Try the old Baseband fix, that did it for me some years ago, not sure if you need the v10 baseband coming from 2.2 but the fix should work. You can find it here on the Forum.
If nothing works, use kdz to flash the Stock Rom and start over.

Thanks, I wanted to try that but when I go to download the milk_os fix at the bottom of this page
http://forum.xda-developers.com/showpost.php?p=14743798&postcount=2
I get redirected to some bull****(lp.downloadsetup.net)
And I just don't trust this thing, is this really what I'm suppose to download?
Is definitely the fault of baseband. Some rom is incompatible with any type of baseband. Try to download from play store an application with baseband-ril match...

Sounds like you have an old baseband phone, but you flashed a new baseband ROM on it. In that case, simply flash the zip indicated below (I suggest you mount /system in recovery before flashing, even though the script auto-mounts /system, just to be sure). I'm attaching two zips for the sake of completeness; the one you want is the Use_New_BB_ROMS.zip.
Use_New_BB_ROMS.zip -- Flash this zip if you're trying to use a new baseband ROM on a phone that uses the old baseband. If you have no network on 2.3 and above ROMS, your phone probably uses the old baseband, so this is the zip you need.
Use_Old_BB_ROMS.zip -- Flash this zip if you're trying to use an old baseband ROM on a phone that uses the new baseband. If you have no network on 2.2 and below ROMS, your phone probably uses the new baseband, so this is the zip you need.

I tried to flash it but I get an error: can't copy META-INF/com/google/android/updated-binary
Should I be wiping cache for this? Dalvik cache?
I used LGMDP-v1.5 to get bb v.20 on my phone in the first place, I tried to do the same with v.10 after v.20 didn't work but it just went back to baseband unknown. when I tried to download the milk_os fix it just linked me to some phishing page.
What recovery are you using? I've tried with AmonRa & CWM 5.0.2.0 and both work. Other CWM versions will probably work, too. Haven't tried with TWRP.
If this flashed successfully but you still don't have service, then you might have borked something when changing baseband in KDZ. If that's the case, then hopefully others will be able to help you as I've never touched KDZ myself.

I tried it, here's what happened.
First I just flashed it, I checked the baseband, it was unknown. Previously it was v.20 so I tried flashing in v.10 since this was a fix for v.10 AFAIK
Still unknown.
Tried flashing the fix again just to overwrite whatever it needed to overwrite and still unknown.
I'm back to square 1 on this one.
