[Q] GSM Radio Connectivity Problem

Last week I got an unlocked defy from Amazon to use with simplemobile in the US. I activated a sim card and everything worked fine (data, calls, texts).
I made a backup with titanium back up, installed IML74K 4.03 AOKP build28 for Motorola Defy and all went smoothly. However, once it was loaded, I could not connect to the simplemobile network and would only get "emergency calls only"
Tried the baseband switcher v4.0, different frequencies and had no luck. In the attempt of reloading the ROM, could not get the phone to boot past the loading screen. Then I attempted to load a full SBF (T-Mobile_MB525_6.19.0_1FF). This resulted in a black screen, probably due to a version mismatch.
Then I flashed JORDN_U3_6.36.0_SIGNED_USAJRDNTMOB1B4B5DE1028.0R_JORDANTMO_P022_HWp3_Service1FF.sbf, and all worked...except connecting to the network. I still get "emergency calls only". I tried baseband switcher and 3gFixUSA found on these forums to no avail.
Does anyone have any suggestions for what to try to get the radio functioning again?
System version:
Blur_Version.3.6.190.MB525.T-Mobile.en.US
Model Number:
MB525
Firmware version:
2.1-update1
Baseband version:
EPU93ST2_U_03.04.02

USAJRDNTMOB1B5DE1028.0R
APflex Version:

Build Number:

I'm having the same problem on t mobile..... ugh.

I got it. I think.
Nevermind. seen you have used baseband switcher...
Does the baseband switch stick after reboot?
But, theres a 3g fix somewhere here... Try here.. http://forum.xda-developers.com/showthread.php?t=897445
Im not sure if that will help... cheers.

Yeah, I tried that exact 3g fix...is it possible that the radio firmware version is too old/too new/just wrong? Is it different than the baseband?

I'm sure you tried all the basebands that it shows... Hm.. I had the problem until I switched to cm7 honestly.. I know the radio cant be old if it worked before. So. Im not completely sure... Except. Im on Tmobile :c

Interesting...well maybe I should try to install cm7 as well. Is there a specific build that you used? Also, did it work out of the box, so to speak, or did you have to do some more baseband switcher tests?
At this point I'm willing to try to replicate whatever worked for you if you would be willing to share what worked, I would greatly appreciate it

Its the build by Shawnshine. But I'm.sure the other builds would work.. and yes mine worked out of the box. I just tried all the basebands for tmobile and one finally worked. Plus try playing with the sim card. I got mine completely bone stock. I came from a evo 4g and a 3D. But I wont have this phone for too long I'm getting a HTC one next month but this phone has been good to me.

[Q] Cant make calls when data is on

Hello Everyone
Last week I noticed that I cant make calls via my Nexus 4. I had fully 3G signal but when i tried to call I had "finished call" a sec later. I tried again, again and again... and finnaly I rebooted phone. After that at last I made a call, but since that I still have the same issue from time to time. I noticed that I dont need to reboot phone its enough when I just turn off the data transmission. Anyone have any suggestions?
Thanks in advance.

radio is baseband. however you need to be more specific about the m9615a since the important information is in the numbers at the end for the exact version like 1700.48, etc

Its version 2.0.1700.48

Note 4 exynos sm-n910k Problem please help

So I am from Canada and picked up the exynos version from a Korean seller on ebay.
Model number sm-n910K I actually have a huge problem. When wifi is turned on phone will reboot whilst in sleep mode after about 5 minutes if I turn off wifi it works fine. Note this happens even if I am not connected to a network the radio just has to be enabled. I am out of options I might rma it to the Korean seller but I think I might have to open a case with ebay, as these guys are being very difficult here is a video attached. I filmed it for 5 minutes but only recorded the last minute. http://youtu.be/ahLB0A2pCOM any help would be super appreciated thanks guys. I am at a loss whether this is software ie corrupt modem from improper driver installation at factory or just a faulty modem things I have tried already.
1. factory reset + cash wipe
2. Reinstall firmware using kies
3. turned off automatic scanning
4. turned off download booster.
The only thing that works is keeping wifi off. Any suggestions would be appreciated thanks.

Have you tried flashing with Odin?

Hey, I also have the SM N910K. What network are you using it on?

I have that version as well without that issue. Can you grab a picture of your About device specs?

Hello there i got same version SM-N910K i didn't have that issue with wifi , but i got battery drain , i live in uk and the phone keep searching for LTE- A ,

N910C with the Samsung SoC
I have the same Issue, i live in the US, I was in Malaysia and manage to get a N910C with the Samsung CPU, when I set the network to LTE/WCDM/GSM (autoconnect) it keeps serching for 4g networks, and it does not switch to lower networks even if available, which causes a huge battery drain, i had to set it down WCDM/GSM for it to get data. I did not have this issue with my note 3 which i also got in Malaysia last year, btw, the note 3 came with qualcomm cpu, and that leads me to believe there is a problem with the modem on the samsung SoC.

Hi! i found a solution where you can force your phone to go to GSM Only, WCDMA only or your preferred network type. In your dialer app type: 319712358. It will ask for a password and the password is 774632. And voila you can now choose what type of network you want to use. This will help with the battery drain.

Hi everybody..im from south korea. I have sm-n910k.

[Q] No signal

Hi all,
First of all, I have a Samsung galaxy s4 from Canada specifically from Rogers. I have got it hardware unlocked, rooted and I am on Cyanogenmod 11.
Now to my problem, I am in the Philippines and I would frequently lose signal, if I'm lucky, it would re-aquire the signal but most of the time, my work around is to turn airplane mode on and off and it would connect back to the carrier for maybe a minute and fully lose signal again.
Any help or suggestions would really be appreciated as it is such a pain to airplane mode and off when I'm jamming to my BT speaker
Here's information about my phone:
Model: sgh-1337m
Cyanogenmod version: 11-20150309-nightly-jflte
Android version: 4.4.4
Baseband version : 1337mvluamdj
If i could help you guys, help me with my problem just let me know.
Thanks all for reading.

Signal issues are mostly connected to the modem,
Flash the right modem for your phone/carrier and see if it help

Hey, thanks for the reply!
I'm a little new to this, could you go in depth on how to do so. Or maybe direct me to a few links I could follow? I am not in Canada and this is my only phone, so I don't want a chance to brick it.
Thanks!
Edit: do I need a computer to reflash the modem because that is something I don't have at the moment.

Here is a modem list. It also has a guide on how to flash.
There was another thread that included the latest lollipop modems , but I can't find it anymore.
You will need Odin which means that you require a PC.
Go to sammobile.com and check what version you need for your carrier and country

No data on Motorola Milestone 3 XT861

Hi everybody,
first of all, I looked all over this forum and also I googled a lot but I was not able to find a solution to my problem. I know that this is an older phone, but it is the one I want because of the keyboard and build. So please do not tell me to buy something newer. So here it is:
I bought a brand new Motorola Milestone 3 in United States (originaly Alltel) and I unlocked it for GMS network with unlock code.
I want to use it in Slovakia, Europe on O2 - SK network. I can make calls, receive calls, send texts, receive texts but I can not get the data service to work.
I tried configuration texts from service provider, I tried to manualy set the APN, none of it worked.
Under Settings - Battery and Data manager - Data Delivery I have both Background data and Data enabled checked.
I managed to root it with KINGOROOT. Before I start playing with custom ROMs to get the data to work, I would like to try to get it to work on stock ROM. I do not mind staying with Android 2.3.6
Details about the phone:
System version: 5.8.25.XT861.ACG.en.US
Model number: MILESTONE3
Android version: 2.3.6
Baseband version: N_03.18.37P
Kernel version: [email protected] #1
Build number: 5.5.1.1-84_D3G-25
Please if ALLTEL has some hidden settings for data access preventing me from getting my O2-SK data access, let me know if there is a trick how to change them or delete them or to do something with it. I really like this phone and I will be very glad if I will be able to use it with data as well. Not only calls and texts.
Things I think might work but need confirmation:
- installing ROM from Motorola DROID 3 XT862 from Verizon wireless
- installing ROM from Motorola DROID 3 XT860
- installing ROM from Motorola DROID 3 XT883 from Chinese operator.
So please if you know anything about solving this issue, let me know.
Have a nice day and thank you for your reply.
