hi my problem is that i cant get any data connection with any of the gingerbread roms....
i have tried different radios, including the ones that worked on 1.83 but i didnt help. i have tried different kernels didnt help. i have tried alien rom 1 and 2 and i have tried cherryblur 1.2 to 1.4d including kennethpenns rom ncrust and the other cherry rom.
what i did....
-flashed 1.26sbf(3g worked
-updated to 1.57(3g worked)
-updated to 1.83(3g worked)
-unlocked bootloader with pudding.sbf.
-installed cwm
-installed gingerblur 4.5(3g worked)
Wiped everything cache + factory even battery
-flashed Cherryblur 1.4d(example) everything worked except data(3g).
flashed faux kernels. (still no 3g)
flashed 4.591 radio from kennethpenns thread (no 3g)
flashed 1.83 radio(no 3g)
wiped everything again......
flashed fruit cake 1.83 (still no 3g)
flashed 4.591 radio from kennethpenns thread (3g working again on 1.83)
from here i tried starting from the top again and still no 3g.
so it seems that my 3g only works if i install 1.83 with 4.591 radio. any help would be apreciated.
sry for spelling mistakes and what not(from denmark)
my atrix is AT/T
best regards.

Yeap that script install the new bootloader ver. and you will NOT DOWNGRADE with previous MOTO sbf for example 1.26 1.57 1.83
So I think your way to make sure if it is software / hardware related will RSD a FULL 1.83 SBF and then apply your provider APN

ah....
so if i install this i will get the updated bootloader and the official gingerbread ota?
and i will not be able to downgrade any more?
i will still be unlocked and such so that i can get alien rom back on there.........
correct me if i am wrong...........
89% done downloading your file.
if i install this would i still be able to use fruit cake to fix any problems and return to stock?
your script finished succesfully now to see if it works.........
hmm still no 3g connection after i ran you script and bootet then logging in to blur and adding my apn.........
any clues why?

Been trying to get my phone to run fully on gingerbread, and have tried the official v20e.kdz flash, as well as Mik_os's CM7, both worked great, and I liked them a lot.
BUT, I can't get my 3G/Data connection to work on either. WiFi works fine, and I can connect to the internet fine that way.
So I am currently flashed back to the gross V10V 2.2.1 Froyo until I can get it figured out. I REALLY want to run CM7, but with no 3G I just can't really use it.
Searches have returned nothing. Any other canadian guys out there with this same problem?
I have a data plan, and I am with Koodo/Telus.
I believe it has something to do with the baseband.
Look here: http://forum.xda-developers.com/showthread.php?t=1217504
Already checked it out, but the V10E image will not work with my phone. I need the V10V image for it to work. Is there a 7z for the V10V platform?

If you want a custom ROM, select one that corresponds to your baseband or switch the baseband. If you do not, you will have no data. That is all to it. End of story.
You can extract the baseband yourself from KDZ archive. http://forum.xda-developers.com/showthread.php?t=901417 (steps 1-2).
All of this covered in the sticky thread.
Got it. Currently have extracted needed files from the uncompressed dz file for my stock ROM. I will be reuploading CM7 and franco's kernel,(Lots of users seem to have luck with it, and I liked it when I ran it for a day) and then flashing my V10V radio and I will let you know!
Edit:
Wait, CM7 currently has a bug so 3G/Data does not work? Shoot! Or am I fixing this by flashing my stock rom's baseband? Will find out soon enough....
And I admit I'm a bit of a noob, I only started doing this last week. I'm learning though.

No dice. My phone was in its factory state when I began this project. It was rooted, installed AmonRa's custom backup, and I installed DrellisDee's Kernel so I could overclock with 2.2.1 froyo. Was stable at 480/768, but it still wasn't enough.
Nandroid backup, google backup, cleared cache, and dalvik. (Thank your AmonRa!)
Flashed CM7, latest stable release 6.5.7
Flashed franco.Kernel.v1-16082011
Booted up, currently running with no issues. Flashed my V10V baseband using LGMDP v1.5.exe .
No errors, everything went well, battery still at 92%.
Still no internet unless connected to WIFI, Damn. Guess I'm S.O.L. on this one eh?
Thanks for the help guys. Gonna check out some other Ginger ROMs and give them a try to see if I can get ginger to work with my 3G network. Any suggestions? I'm stuck with v10 based ROMs since LG hasn't released any V20 setups for my network.

You can't tell me how you got the phone rooted in the first place can you?
I'm with Koodo and have the Froyo 2.2.1 firmware on there.
I've tried everything I can do to get it rooted, and it just won't!
Gingerbreak says that there is a problem and won't do it.
Superoneclick hangs on step 6 which is mounting the SD card
I tried to grab a v10_G flash which is the telus stock ( I think ) but there was an error while trying to flash with kdz flash ( update error param =2 ).
Can ANYBODY help me to figure this out?
I havd koodo, just last friday I rooted 2 friend's phones with the gingerbreak app from xda thread. I took the second one and at first it didn't work because there were too many dots in the file name, simple as that, took me a while to figure it out, so I renamed to something like gingerbreak1.apk and it worked. For the data not working, just google " koodo apn " then you'll end up with the good apn info wich is simply. " sp.koodo.com " , port = 80, NO proxy as it just slow down the net, the other settings as they already are, 302 and 230 or something like that they come as default near the bottom of apn creation option in mobile options. All other fields leave blank. Hope it works..

I decided to install a different version of gingerbreak, and suddenly everything worked so simply...
I have since installed clockworkmod and have done a full back up.
Then I installed cyanomod and everything is up and going.
I was nervous to flash the google apps, but everything is happy.
Oh ya... I did have to update my apn data to the koodo network. I've tested MMS in and out.
You might want to try Andy's Phoenix rom; the fastest one and amazing statusbar. Some light text issues will be fixed the 20th october update. Beside that, the best for me with franco 2.6.35.14 oct. 2 kernel. Anyway, glad you could make it

In your opinion do I need to flash the radio.zip after cm7. If so wat does it do for my device? Do I get better service/ faster data speeds?

I think the radio that you have currently should work well enough.
I had the 1.97.00 radio and found that cwm was giving me a 1 bar issue. Same thing with aosp. And input so I installed the 1.77.30 radio via cwm. Wish I had a cwm version of the 1.97.00 radio just to try while im at work. Seems the 1.77.30 radio switches from H to 3g less in my area than the. 97 radio.
ok, it seems as if my service is pretty good compared to what yours was before you flashed it. ill keep it for now. thanks for the replies
Please help Radio flash
I want to flash the radio to my unlocked and cwm installed atrix 4g. I used to have 2.3.4, 4.5.91 ATT stock software, but went to cyanogenmod 7.
What radio do I need to flash in cwm? There is a radio.zip file on briefmobiles website, I just want to make sure I am downloading the correct one.
I want to flash because it is taking a while to get a gps lock in CM7, where in the stock rom it would happen almost instantly.

Not 100% sure but gps lock on isnt slow because of radio but couz of CM7 i got stock radio and its also slower then on GB. also CM7 doesnt install radio if im not mistaken if u had GB radio u should still have it
what cm says
code.google.com/p/atrix-dev-team/wiki/FAQ CM7 is saying if you are having slow locks to reinstall the radio. I'm just wondering how I can accomplish this through cwm.
[Q] [Help][Stock AT&T 2.3.4 Build 4.5.91]No network after *#*#4636#*#* > USA Band
Hi guys! Plz help.
I have AT&T Motorola Atrix 4G. Its SIM Unlocked and Bootloader Unlocked as well.
System version: 4.5.91.MB860.ATT.en.US
Android version: 2.3.4
I am using this mobile phone in India and had no problem at all with 2G and 3G networks.
Today I was going through *#*#4636#*#* > Phone Information > Menu > Select radio band > and selected USA Band accidentally. Thereafter I have no GSM network. I tried manual searching of networks and did a Erase data/factory reset in CWM recovery but had no luck. I tried to restore an earlier backup also but due to MD5 Sum Mismatch error I couldn't do it.
Please help me getting my mobile working again. Is there something which can reset radio frequencies of the phone? Any idea what should I do now?
Thanks you so much for your help.
Hey there!
I had same issue a while ago and didn't have unlocked bootloader back then.
I simply re-flashed stock firmware from this thread and everything worked fine. If you do this then make sure you chose right one (For you first one should be right), If you downgrade to 2.2.x you will hard brick your device. Just keep that in mind.
By the way now I'm using [CM7 ROM][24/12] --> Neutrino ROM 1.4-S <-- [53mb] and there in settings you can choose whatever band you like unlike in stock AT&T firmware from *#*#4636#*#* you can chose only USA Band. There must be other roms what support this feature too.
I'm sure there are other ways to fix this issue but this is from my expierence.
Good luck!
PS I did that in first week when I had Atrix and it was my first android device. I managed to fix it, I'm sure you will fix it too

Hi mm166,
Thank you so much for your reply and I do think a re-flash only can fix my mobile. Since I have Bootloader Unlocked so I think I can't use SBF method to flash stock 2.3.4 and I can only go for fruitcakes. I am now downloading ATT 2.3.4 Build 4.5.91 fruitcake and I hope it will fix my mobile
I am woundering if flashing ATT radio .91 from following link will reset the files responsible for holding network settings and can fix my mobile ... but I am not sure so can't go for it
http://forum.xda-developers.com/showthread.php?t=1163009
Update:
I just flashed "2.3.4 System and Boot NO Webtop (Updated Newest Script)" fruitcake after Clear Data/Cache/Factory Reset but still no network
I think I have lost my mobile just because of accidentally setting to USA Band.
Any help please!!!!!
Well, I'm still newbie on Android devices. I'm not very long with Android device but I'll try give you few advices. Keep in mind that I could be somewhere wrong:
I think new script: [Batch/Script] MFBSR - Moto-Fastboot: Stock Restore could help. Worth trying. Fruitcake didn't restore everything.
I used RSD SBF flash and I think it doesn't matter if bootloader is unlocked or not (maybe someone could confirm that?) if you flash same firmware but that's somewhat risky (better don't try this). But I did that and everything worked great.
Other way to fix network issue could be flashing custom rom. For example this. I added screenshot from settings. Edit: No, I think I'm wrong. That's not right thing.
Solved!!!
Hi mm166, thank you so much for your reply
Before reading your message I did a trick and it worked for me. I just flashed ATT Basband/Radio N_01.77.36P FruitCake through Rom Racer's CWM and after reboot my phone was able to find network as it should be
Since my phone's BL was unlocked so I was not supposed to try SBF flashing to prevent it from hard brick. And, just flashing Stock ROM FruitCake was not resetting its radio settings i guess ... and flashing particularly above mentioned radio files just replaced the older one and once again my Atrix started to breath
I hope this may work for other guys too who are facing same kinda problem of not getting network after accidentally setting the radio to USA Band. But a Full Wipe/Factory Rest/Data/Cash/Dalvik Cache Wipe is needed.
Hi all
I dont know why / how but my cell radio suddenly went off and wont turn back on.
I am rooted BL unlocked on Nottachtrix 1.3.1 ROM.
I am also SIM unlocked and I live in India. I have the AT&T atrix.
What might have caused the issue
I was messing around in *#*#4636#*#* with the radio band.
I had this signal boosting app which I use but cant find it on the market to link it now. I 've been using this app for a while so dont know why it would mess up now.
I am not sure if these are what caused the issue but just letting u know
Things I have done so far
Battery pull
Different sim card / different network
I tried flashing the ROM again with full wipe but still no luck
Flashed CM7 Ba2tf and the problem persists.. can I rule out that it is software related?
Everything else is working fine.
I am out of ideas and help is very much appreciated.
Thanks
SOLUTION
The Easiest Fix for this issue is Flashing the right baseband in CWM recovery.
The radio is flashed separately from the Android os. Try a new baseband. However be sure to get the right one for your phone.

Issue solved. I 'll detail what I did so it can help others.
Yes. Selecting the USA Band is what caused the issue.
I dint know that basebands could be flashed on Atrix ROMs. I wish I 've known it sooner. Would 've saved me a lot of trouble. Anyway I went with the SBF method.
I had the 4.5.91 earlier but I went with 4.5.141 to be safe.
Everything went smooth but at the end RSD lite said "Please manually reboot this phone" and the phone went into a boot loop at the M logo. I looked around and after a while found that a Wipe fixes it in stock recovery.
1. Disconnected the phone
2. Pulled out the battery.
3. Rebooted and went into stock recovery.
4. Wiped data and rebooted.
5. Got to home screen fine. Rebooted once again to make sure everything is fine.
Then inserted sim card and I had a signal. Everthing is working great.
Bro i have solution.... Btw... You must have flashed the wrong rom.... Kindly download nd install other one ..or use custom cm14 ROM or miui for best experience..
Operator: U Mobile (Malaysia)
Rom: 2.3.6(4.5.1.41.MB860.ATT.en.US) flash with CWM using fruit cake rom.
Baseband: N_01.77.36P
Kernal Version: 2.6.32.9 a21`[email protected] #2
Status: Can make call and receive sms. Apn setting is good. Wifi and bluetooth also work fine. Only mobile data state is the problem.
Problem:
1.I got this Atrix last 3 week. When i put a sim card it cannot detect my data so i install TWEAKKER from Play Store and get the setting for my APN. Everything work fine.
2. After a week i unlock the bootloader, install Nottachtrix, and again using TWEAKKER to set my APN, have fun with lapdock (overclock it using faux kernal to 1.45ghz). Everything still work fine.
3. Last 5 days i start play around with Titanium backup and supercharged v6. I backup and remove system application that i think i dont need it. I end up with mess around with the system but since i already made a backup i just restore it to default and then i start notice i lost my data signal.
4. I reflash fresh nottachtrix rom using CWM but the data still disconnected. I try flashing other rom like ICS rom also same problem. And then i flash official rom using CWM (fruit cake method) and RSD method. Still no luck. But today i play around with HiAPN and i can connect to data again but it seem not stable. But i can receive Phone call and sms without problem.
5. I already check my sim card by put it to other phone and i got no problem with it.
Any suggestion what i need to do to make data work again normally?
Update 18 May 2014:
1. I reflash 2.3.4 rom using RSD. Mobile Network State still disconnect. I will buy a new sim with different operator to test either my phone got problem or is it the sim/operator problem. Old but powerfull phone. I hope i got change to use it as daily phone again.
Update 21 May 2014:
Already test with other operator also no luck. Flashing all the radio that i found also no luck. Guessing the hardware got problem but quit confuse because call and sms still can receive.

Not a smart advice, use it as last resource:
Find the radio version your phone have and flash it, or simply flash another radio. Be careful, tough as an incorrect version (not all radios work on every atrix) you may end with a nice hi-tech papeweight

Already call my operator services and they also can't help. Today will try another sim card with different operator that i will borrow from my friend to check either i need to upgrade my sim or not.
Still hope to get any expert help from XDA forum
Any expert? I got iPhone and windows phone but nothing can beat this atrix+lapdock.

Hallo miogy,
this is a well known issue,
i am experience the same problem with my atrix 4G,
i recently flash the CM9 of CyanogenMod , (android 4.0.4),
before that i had the 2.3.4 (GB) - in this version my atrix had restart himshelf every day.
on the current version (CM9), i experiencig strange things with the Network.
this is not only us that experiencig that - it is a very common and wide .
its called RIL bug (RIL --> Radio Interface Layer),
my phone can work fine 2 or 5 ot 8 hours, and suddenly the data connection disconnected.
i even once had connected to a Mobile Carrier that is not mine.
as much as i understand till now, this RIL bug is caused of a bug in the Kernel, adn the best guys here in the XDA, are trying to solve it.
i am waiting to this solution very much, because this atrix 4g is great phone, and i like the CM9 also.
you can see for example this thread:
