[Q]No signal in 2g mode on CM9 - Defy Q&A, Help & Troubleshooting

Hi guys,
I have defy +, i have installed CM9(Epsylon Build). The problem is that when select 2g only mode, i lose signal and there is not network. I tried changing network, but nothing works. I get signal only in 3g mode, but no signal 2gb only mode.
I live in chennai, India and I am on aircel network.

Install baseband switcher and configure to south india 3.4.3_221.
cm9 has inbuilt baseband, but the settings were not persistent, off the late i didn't check though. Go to settings and device settings, choose the baseband as Asia,3.4.3_221 and reboot.

[Q] MB526 no signal

Hello,
after a succesfull rooting attempt on my motorola defy+, i seem to get next to zero signal. (root tutorial: http://forum.xda-developers.com/showthread.php?t=1595013&page=9)
Is there no single way to restore the phone to default, without all the rooting? i really regret messing with the system and i wanted it the same way i bought it.
Or atleast get a perfectly fine signal as i did before the flash.
My location is belgium, and i have no clue what baseband setting it would be or wich sbf file i need to fully restore :C
Match your base band to the network your using with this. I would have try central Europe first.
You probably had DFP231 so my best guess would be using this sbf.
Second guess will be using this one, all from here.
Thank you

I thank you allot for helping me find the right things. i reflashed everything back to stock.
However, Wich sbf file would be for belgium? it's western europe. these others work okay but the baseband doesn't seem to do well, my signal for 2g and 3g are very poor now. is there absolutely no way to fully restore back to this device's original stock? the one i bought in belgium?
and the marketplace keeps crashing on either of those SBF's.
on the phone box you should see the baseband you had when purchased, it will help if you check your carrier name and baseband.
Maybe you had the France retail version, being also a French speaking country.
If you using Mobistar than the frequency for 3G is 2100, which should work with the current sbf.
Try removing the sim card and back again. restarting once or twice. sometime it need relearning the network.
Look in setting, "About", "Status", you should see the signal strength. Good reception is in the scale 51-100dBm.
113dBm-No reception.
Here's a sticker on the box, i'm not sure wich says the baseband.
i appreciate your help.
It says your original sbf was setup to 900/2100 Wcdma and 850/900/188/1900 for GSM. Your current sbf should work just fine.
If it's not working then install the French sbf, Orange France is using the same as yours original sbf.

Ohh, I see, thank you!
i use proximus, but i'm sure that's the same thing. anyway thank you again.
i did get signal on the sbf you supplied, but it always said "network unavailable"
Indeed, Proximus use the same frequencies as Mobistar.
Go to settings, Wireless and Network, Mobile networks, Operator selection, Serch network. See if you can find Proximus. If you do, click on it.

hmm, i switched the sim card in and out, but i still get connection unavailable on network search
Strange...
Try flashing this sbf.
Hey there, the issue was fixed by simply setting my radio to prefer WDCMA.
Once again i thank you greatly. You have helped me out so well. I added 3 thanks to your account

I'm glad your phone is usable again but from what you did your phone apparently can't work on 2G.
I would have use that sbf and see how it's working, now that you can always go back to the current one.
Anyway, enjoy your Defy.

Try another modem
Or look if your settings support LTE it might be set to wcdma

In Foxhound OTA settings, there's a LTE Fix, download it and reboot to recovery and flash it

Thanks! I got LTE
Did the LTE fix cause a new radio modem to be flashed? Could there be sensitivity degradations as a result?
Would this only affect LTE mode ?
I get (indoor) -85 to -95 dBm on UMTS /HSAP depending on position - in LTE mode I get -92 to -109 dBm in the same positions
Appreciate the help

Hello,
I answer here to help also someone else in case has the same problem.
Fiest thing: you wrote CDMA module, what variant is?
The GT-I9505 has a LTE/WCDMA module, not CDMA.
Have you touched something with secret menu codes? If you don't know what they are, the answer is no
What carrier do you have?
Have you roaming enabled?
You data plan reduces connection after a total GBs used at maximum speed?
Try to flash latest available modem fw along with latest bootloader, you can find them here

Thank u for ur reply,
First you are right I'm talking about the LTE/WCDMA module, and yes i messed up a little bit the with the secret menu codes but only after i got the issue, not before that.
I'm from morocco so the carrier is a moroccan one called inwi, the carrier does not reduce the speed, when u consume the GBs given the service is suspended.
the issue appeared when i was using wanam lite 3.1 i'm using wifi at home all the time so i couldnt notice until i went out and used data, i noticed that i only have edge in locations that used to give me H+, so when i tried to force wcdma by choosing wcdma only i got emergency calls only.
i messed around before with a couple of bootloaders and modems, I still cannot figure it out
your help is appreciated, thanks in advance
I had the same problem on Wanam. What solved it for me:
Use Shortcut Master (lite) to go to this menu: 4636
Then go to phone information and change the bandwith to something else. Then set it back to LTE/WCDMA or whatever works for you. Strange but it worked for me.

Get the network cable changed or change it yourself.
The only easy "non software" related solution.
Or maybe if it is in the software, tried flashing the stock rom or any ither custom rom after a full wipe.
Mine was with the stock rom but ozcan rom + data wipe has solved it..
Not i get H+ in only wcdma amd E/H+ in auto mode. (depending on the network area)
