[Q] GSM Radio Connectivity Problem - Defy Q&A, Help & Troubleshooting

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
Kernel Version:

BPflex version:
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.

Try some troubleshooting. Test his sim on another phone and see if it works there.
Is he on a custom rom? Creeds Rom 3.4 had a bug where you cant see the signal even though it has a signal. Can he still send messages even when signal bar is X?
Also, APN wont do anything for the signal, its only for mobile internet browsing with your carrier. Hmmm... are you talking about surfing through your carrier? or basic services like calls and texts?

Thanks for replying! It's running creed's v2. When you try to place a call it says "Mobile Network not Available". I tried his SIM card on an unlocked Atrix 4G and it made a call successfully. Texting doesn't work either. He said when he had this problem he took it to some unlock/repair shop and they failed to state what exactly was causing this.

If all else fails, go back to stock rom or try another rom
(Though I suggest latest stock rom with merruk kernel and superuser opened)

Your phone is network locked or something like that I guess.
Best way to get it solved is to post your query in this thread:

Doky73 will surely help you out
I advise to flash this pack: S5360B_UTLC2_ZTOLC_UTLC1 (open Brasil)
Flash all 3 part (PDA, MODEM, CSC)
If it does not help, then send me your bml15.img.SAVE (made by Galaxy Toolbox)
hey pal i also encountered this kind of problem before after patching Creeds ROM. What i did was I reflash the rom with stock Galaxy Y via ODIN or after the first successful boot of selected customize ROM. then you will need to apply the CSC depending on what network your country has. like mine i choose either from SMA/GLB/XTE. just dial #272* IMEI code. I hope this will help.:good:

Defy+ plus no network - change baseband doesn't fix

so.. I have this phone parked in my drawer for almost a month and finally decided to seek for online help.
Last rom installed is cm7 (but i've tryed several others cm7.2 cm9 cm10 cm10.1). I've tryed using both the baseband switcher included in the rom settings (where avaiable) and the standalone apk. I live in Italy so I chose Italy in the baseband selection (again.. I've tryed several others basebands just in case...). The sim card is a working VodafoneIT sim card and it is recognized by the phone.
the problem is that my phone does not lock to any network and I see the message "emergency calls only".
I also tryed to flash original sbf from here.
I don't know if it matters but logcat reports these errors:
Code:
E/GSM ( 6427): RIL implementation has returned an error where it must succeedcom.android.internal.telephony.CommandExcep tion: GENERIC_FAILURE
D/RILSWITCH( 2018): RILD unknown at cell -1
E/GSM ( 6427): Wrong network type: 0
I remember that at the time of when the problem showed up the first time, looking on the internet, in addition to the advice of changing the baseband, I found a thread where someone was talking about a possible hardware fail.. but I can't find it anymore.
any suggestion?
thanks
up????
i'm also having this problem
anyone found the fix?
Does the same error occur in stock? If so then I think it's a hardware issue. You could try a different sbf of your carrier and region(a newer one), but I do not think it would help much.

Try with different bands from your country or another country with the same frequencies.
Pull the batery out for a few seconds.
Use the latest version of the standard app (not defy parts).
Regards,
It works for me with a different company of my country
My chip is Personal_AR and with this don't work, but with Claro_Ar works fine...
THX it's make me crazy

[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

Hello,
Do you find an issue ? I have almost the same problem. I think the problem is un baseband problem but i amn't sure !!!!
which country are you from? I think its got something to do with the firmware version or perhaps the frequency of GSM/LTE is different from where you bought it and where you're actually using it now.

Sgh-m919 stuck on 4.4.2 stock with a 4.2.2 stock baseband.

I tapped on a setting in the *#9090# menu. At this point the phone will only find service with the lte discovery app. I can register on ATT TMO VRZ. yet when in a call there is no sound. can confirm calls go through. If the unit is on any other bootloader or baseband there is no service and mobile networks is not accessible , it says insert a sim to access. the baseband and any other info in the about phone status menu is unknown cept for the ser.#. I have a twp bkp of JDC 8.1, and the latest tmo stock tw backed up. they are no help. my questions are what have I screwed up and is it fixable. thank you for your time

Now, I have the newest bootloader for SGH-M919 ending in FQA1 (4.4.4) and the only working baseband is still UMDL (4.2.2). I'm running 8.1 JDCTEAM, WiFi and cell are working great. But Why cant I upgrade the baseband?
