[Q] No mobile signal after CM9 + modem, but can see networks

I flashed the latest CM9 nightly two days ago, and everything seems to work great other than that I have no mobile signal. I am an Australian Optus user, and I tried it both with the modem that came with CM9 and with the one I believe is for my country, which is XXJQ3 by flashing that.
In both situations, I can scan for networks and see all three carriers just fine, but it shows no signal, just an "x" in the middle of the signal triangle, nor does it show which carrier it is connected to. I cannot make emergency calls because it says no mobile network is available.
Is this a modem baseband/firmware problem ? I am guessing not, because I would think that if it can physically see the networks, then the modem must be working right ? But if so, why can it not connect to anything ? The modem firmware I am using is for ICS and I believe it is the correcto one for my region, and I have enabled everything in the modem settings but still it will not connect to any network. Why ?

did you have try replace/update the modem radios from this? http://wiki.cyanogenmod.com/wiki/Samsung_Galaxy_Tab_(GSM):_Support_Downloads
you can try a different modem, It doesn’t matter if you prefer another modem, you can flash another modem, you can try flash any modem file you want, it's will not brick your tab
If you had, but still not working, then go to dialer, put this code *#*#4636#*#*, pick tablet information, try turn of the radio then turn on again and try to fix permission on cwm too.
good luck.

Thanks. Tried all your suggestions. Yes, that is where I obtained my XXJQ3 modem, which I flashed via CWM. I tried your other tip of turning the radio off and on again and then fixing permissions in CWM but to no avail. Still no mobile signal.
Is it correct to assume that if the device can scan for networks and see networks, then the modem is working ? The information screen you directed me to says "emergency calls only", but I cannot actually make an emergency call because it says "mobile network not available", so even though it can "see" three networks, it cannot connect to any of them to either get a signal or make emergency calls.
What does this mean ? Surely it has the right frequencies set otherwise it wouldn't see the networks at all, right ? Is this a CM9 bug in the nightly I flashed or something ? Wondering where to look. I get the feeling the modem is working fine and that something else is wrong.

I use the jlv modem from the vibrant phone.
But jpz modem is also OK for optus.
Why not do Android backup for safe keep, then restock using gb stock safe from overcome guide, and flash jpz modem to try.
If it is the same, then it is hardware related.

Oh my god. The reason it didn't work work is so stupid I had to headdesk when I realised. The SIM I was using was old and had been disabled. The reason I didn't think it mattered, is that in Gingerbread, it would still register and show reception bars and I could make emergency calls with the old SIM, or indeed even without a SIM in the device at all. But in ICS, none of that was the case, and it would not register and not let me make emergency calls without a valid SIM.
I guess I was just making a stupid assumption that SIM-less emergency calls that worked in GB would also work in ICS. Stupid me.

Everyone can make mistakes or forget something, but you should thank all the users who give you answers.

HTC ONE HTL22 Radio Problem

I have a HTC J ONE HTL22 and a few days ago I lost my network signal completely. Contacted my network provider everything was good,bought a new sim tried that and still no network. The day I lost it I went into the service menu #*#*4636*#*# and into Phone Information and was just trying some different network settings. I clicked select radio band...and I saw Euro Band,Japan Band,US Band ,AUS Band ,AUS2 Band. I tried US Band to see the result and than i lost that menu ,now I only see Automatic, Cellular(800-MHz Band) and PCS(1900-MHz Band). When I try Automatic it says Unsuccessful. The other 2 successfully work but don't give me my network back? I've done a factory reset and still nothing changes. When I manually search for a network,it comes up blank. before it showed Bell,Telus,Rogers etc. So it's defiantly something with my radio.
My cell is UNLOCKED, S-OFF, CID-11111111, HBOOT-1.54.0000, RADIO-1.23.11.0829 and CWM installed,running stock 4.2.2. So I'm wondering is there a way to reset my radio or any help on flashing a new radio? Thanks

Thanks for the link. Today I tried to install a new radio through CWM. I pick the zip to install and after a few seconds it says complete...I reboot and my radio never changes. I've tried it through CWM and Rom manager. Am I doing something wrong?

This might be of a bit more value. It seems the prior link was for a different HTC One model. Above link is for M7. Check it out if you still need a radio/baseband.
I also realized your phone is a Japanese variant...I dont know if that makes a difference or not in compatibility, but I wanted to mention you could try using ADB to flash the radio/baseband instead of using recovery. I think you could also upgrade your firmware,which usually includes the baseband. Good luck...

Thanks for reply
Nothing help
flash radio through fasboot and TWRP does not matter

Same here...still no luck yet. Still have no network. Makes no sense why the radio bands cant be restored!?

many service centers, many ROMs nothing help

Hello,
Did you got it working ?
Many people in Austria have since mid of July problems with the Droid 4 GSM.
I used the Original JB ROM with Mentor, but since mid of July it didnt found any GSM signal anymore.
Now I have installed CM11, GSM and Internet works,
but the GSM works only with 2G and the Internet only with EDGE mode anymore.
Did you found maybe already a solution to get it fully working again ?
We cant find any solution...if you know something, let me know please.
regards

I can try to helping you but you should answer to these questions:
Did you do some change before to not having anymore gsm signal?
What is your stock rom version?
With the original stock rom without any modification what is the situation?
Could you try the original stock rom without my gsm rom but with my latest gsm patch?

I'm in Austria too (provider yesss) and i'm facing the same issue. I already did an full wipe, went back to stock, rooted, installed safestrap again und finally slimkat 7.0 with the gsm patch. Still i just get an edge connection but whenever the droid tries to connect to umts, the signal gets lost totally (no service).

@Mentor.37
i did not any changes - it didnt worked anymore from one minute to the other
i used the Original JB ROM with the Mentor ROM (i cant remember the exactly ROM Version, but it was the official Stock from Verizon/Motorola)
With the original Stock ROM i dont get any connection (no telephony and no internet) - also not any 2G connection...
With the Original Stock ROM and Mentor ROM its the same....no connection (no telephony and no internet).
I flashed CM11 and there i got a connection, but the connection is only 2G (telephony and the internet works only with 2G mode) - no 3G mode.
I also flashed the "Original Motorola Image" back, but there i didnt got also any connection
I used some "Moto XT894 Utility" which i found here in the forum - but always the same - no connection. The "Moto XT894 Utility" contained the Original JB ROM.
@magikstar which Tool you exactly used for flashing back the Original Image ? Can you send me maybe the download links ?
Maybe you have used another tool for flashing back than i.
As Provider i use: A1 (Telekom Austria)
many other people in Austria have the same problem....

@lzmichael
My provider is YESS!!, which belongs to A1 and therefore I'm in the A1 network too. Seems like an A1 issue, because a friend of mine (he has a droid4 too) has Drei, and does not have a problem with 3G.

go to http://sbf.droid-developers.org/phone.php?device=11 and download the latest firmware Android 4.1.2 Blur_Version.98.72.188.XT894.Verizon.en.US
then unzip it and boot your phone into bootloader
flash via fastboot the boot.img,emstorage.img,preinstall.img,radio.img,re covery.img,system.img
and reboot your device and finally mentor's rom wia safestrap

not working
thanks, i did that....but it still works only with 2G mode
with 3G it didnt connect (no network)
what can i do ?

You could try installing the stock 18-9 version, if i'm not in error in it there has been some little update in the radio for gsm users in the canada and that could help every gsm user.

I dont have installed a GSM Patch (i never had that installed before), but i can try.
Today i have installed:
VRZ_XT894_9.8.2O-72_VZW-18-8_CFC.xml.zip
and the MentorRom (Version from March 2014).
With that i have 2G connection. 3G didnt work.
The same problem was with the CM11 - only 2G worked
Where i can get the 18.9 Version from the Stock-ROM?

If you are using my rom you do not have to install the gsm patch but if you are using any other aosp rom you have to install my gsm patch.
Now for testing you can try installing my latest gsm patch, in it i made some change that i have not yet merged in my gsm rom, if no luck you can try updating to 18-9 in this way:
- install the 18-2 version, here the download
- from ota you should update to 18-9
- now you can try the stock rom without any mod and with my patch
if these things will not help we will try in another way.

I have installed now the latest GSM Patch (v3.2.2), but it still doesnt work with 3G mode (no internet connection and no telephony with 3G)
...if i switch to 2G it works
(for example: with a Drei Austria sim card the phone works fine - and with T-Mobile Austria is the same problem as with A1).
I will try to install that 18-2 Update later, when i have a fast WLAN connection to get the OTA update (to 18-9) quickly...

im wondering that that problem only appears in austria. since mid of july...much people have problems

There is something that your provider changed and that that caused this, I hope that we will solve the problem but with our locked bootloader this will be really hard.
Have you tried contacting your providers to knowing what's happening?
Anyway if after updating to 18-9 the problem will be yet present you can attach here your logcats when you are in 3g with no service.

Yes, i have contacted the provider in July and have asked what i can do. i have then asked if they had changed something - like APNs or so, and the provider said, that they didnt changed anything. they replaced then my simcard - they thought maybe is the simcard defect, but the simcard was ok, anyway i have now a new simcard.
but the phone-support from the provider didnt know if something "internal" got changed at the provider...thats what i think.
After flashing the stockrom (with mentor addon), i got a 3G signal for 30-50 seconds, then the signal was away.
the same thing was end of july, after flashing the stockrom (there i had some older version flashed), i got a 3G signal for few seconds - then never again.
no 3G signal after rebooting and so again - it worked only short after installing the new rom.
How its possible to get that "logcats" ? I never did that before. In which directory or so on the phone are the logs ?.

Pretty interesting the output of the log.
I'm writing from my droid so a full log may be diffult now.

I cleared the log before I captured the radio log. At the beginning I had an established 2G (GSM only) connection. Then I switched to "GSM auto(PRL)" - the connection dropped and finally I went back to "GSM only" again. Just fyi what I was doing when the log was captured.

i9305 Galaxy S3 LTE Signal Problem / fluctuates

Hi,
can You help me pls with ny LTE i9305 S3? I have problem with signal (antena OK, any sim any network), is just good outside but whan I go somwhere in house, is very bad or stop working network. I am not sure if can be some chip on motherboard problem, or if I solve this problem by some flash.
Thanks

Does it happen when you go inside in any place or just in your house? If it's just in your house then clearly it is just a problem of coverage on your area. I9305 international version supports bands 800, 1800 & 2600 for LTE where both 1800 and 2600 have bad coverage inside buildings. Check as another test if selecting 2g (pure GSM 900) you still have bad coverage. Can you try with a SIM of another carrier? This could also be the definitive test.
If it is a common problem (anywhere, any carrier...), then maybe you can solve it by flashing with Odin a different modem baseband (also called radio).
You have some basebands for download here:
http://sourceforge.net/projects/djb-tgp/files/CWM_Flashables/Modems/4.3 Modems/
I'm using the XXUENA2 with very good results, been used before others also with no major problems (XXUEMK1 and XXUFNI3 for example).
This is my "About device" screenshot where you can see the Baseband I'm using. Works fine in Europe as well as in Brasil:

1) About signal: how do you expect to get signal without SIM? Or maybe are you meaning signal for just the 112 emergency call?
2) Modem/baseband: I already provided the link in my original post, check it.
3) No need to downgrade. You will only flash the modem/baseband without touching any partition, neither the ROM nor the EFS. You can do that via Odin (check any Odin How-To document -search Google-) or via the recovery if you have TFRT or QWM (at recovery menu select flash zip file and choose the one for the modem -you need to copy the zip file previously to your sd card or internal memory).
