[Q] T-Mobile/AT&T/GSM on Razr M

This is the method that I used with RadioComm. The method posted in this thread also works.
Both methods accomplish the same thing and that is to edit the NVM in the radio to allow open GSM service on US carriers.
deep sleep
I had strange behavior after the upgrade to 4.4.2 on a radio hacked Razr M I've been using with AT&T/Straight Talk for a year. The phone refuses to go into deep sleep when 3G/HSPA is enabled. This causes reboots and fast battery drain. It's fine with data disabled, GSM/2G only, and wifi. Lots of settings fiddling and factory resets. Using RSD Lite to flash stock 4.4.2 hasn't helped. I tried a friend's AT&T SIM and had the same problem, 3G data worked fine but no deep sleep. Anyone else see this behavior after the OTA upgrade?

There is a bug in the Modem Fast Dormancy app that causes several problems using the M/HD on GSM services and I have found it is best to disable it in the build.prop
along with a few other edits that optimize the radio and remove some of the VZW specific features and settings that can interfere with GSM/WCDMA functions.

Thanks for the response. Any tips/links on how to do this with 4.4.2 KitKat? I haven't seen a Razr M root method yet and definitely don't have the skills to develop one.

i put my tmobile sim card that is activate in my gsm unlocked razr m and turn it on first it says no gsm umt networks and ask if you want to change to global and when i hit no it reads no service anybody got a clue what wrong its gsm unlocked i checked
Do you have these edits listed somewhere? If they make my phone perform better, I'm all for it.
I will be writing this up in my thread but will give a quick listing here.
At the bottom of the build.prop file is a section called ADDITIONAL_BUILD_PROPERTIES and there are three lines that need editing.
ro.mot.phone mode.vzw4gphone=1 change to 0
ro.mot.ds.fastdormancy.disable=false change to true
telephony.lteOnCdmaDevice=1 change to 0 (the first instance of this line higher up in the build.prop can be ignored as this one takes precedence over it)
These changes can be made with any root enabled file explorer or with adb shell but you must always remember to set the permissions properly to rw-r--r--
and always save your original file as .bak to restore in case of problems.
If you do not set permissions properly your phone will not boot and you will need to reflash the system to restore it.
Also removing or renaming /system/priv-app/VzwPhoneService.apk and .odex files will disable the SIM from Unknown Source popup warning.

Thanks for the information. Could you elaborate on the benefit of making the edits? I understand that disabling fast dormancy will work around the bug, but what benefits do the other two edits provide?
On the new KK build the location is s now /system/priv-app/VzwPhoneService.apk and .odex.
It's listed under Titanium as "com.motorola.setupwizard.phoneservice". I would freeze it while you're in titanium rather than uninstalling it, so you can take OTAs in the future. That is, if you care about that kind of thing.
Dear friend, did you poke around in NV to disable fast dormancy?
I have razr m with latest ota and use it in gsm network outside of US. There is no root to edit build.prop and it will be great if we can disable FD from NV.

34Got H+ on Net10/AT&T
I used DFS (from cdmatool.com) & dev drivers from somewhere on XDA to set NV item 8322 to 0, and now I have H+ on Net10/AT&T in the US, with the US modem. Still says "Sim from unknown source" on boot, and remember set your APN correctly. Please report if you get this too, maybe there's something else I changed that is also important.
Super thanks to CellZealot, P3Droid, and everyone else for investigation, I wouldn't have tried if you didn't.
Happy hacking15
The zip file would be super convenient...
But, I'll try to give a brief step-by-step "cheat sheet" guide here. Not a real tutorial, sorry ... don't have time to go back and try all the steps, take screenshots, etc... for the "easy way" I'd wait for cellzealot ...
I installed the drivers for all the tools like DFS, QPST, QDXM, etc long long ago, not sure where but I think the ones from this thread should work:
Drivers: http://xdaforums.com/showthread.php?t=1891582&highlight=drivers
Direct link: http://xdaforums.com/attachment.php?attachmentid=1333751&d=1347903431
After installing the drivers, power off the phone, then hold power + volume up + volume down, and select "BT Tools" from the boot menu (press volume down until it is highlighted, then press volume up). Wait for the phone to boot, then plug it into the PC. It should recognize it and install a new COM port (if not, go to Start->Motorola->Mobile Drivers->Motorola Drivers Installer and see if that does the trick.. again, I installed these drivers long ago so my memory is a little rusty).
After installing the drivers, install DFS, I got it from this thread and it worked, you may get it somewhere else as well:
DFS: http://xdaforums.com/showthread.php?t=1876457
Direct link: http://www.2shared.com/file/xBxUOnPz/DFS.html
(1) Make sure you still have the phone in BT Tools mode connected, and start DFS.
(4) Click on the "Ports" button, double click on the newly installed COM port (for me it's called "Motorola QC Diag Port"), close ports manager
(4a) Check: Make sure the port is selected in the drop down to the right of the "ports" button
(5) In the main window, select "Qualcomm" on the DM drop down
(6) click on SPC (leave code as 000000), make sure it says "DEVICE UNLOCKED" in the console at the bottom
(7) click on NV tab
(8) enter 8322 the "Start" field, and 8323 in the "End" field, then click "Read range"
(8a) Check: It should show only one item called ITEM_8322
(9) select (highlight) the item ITEM_8322, click in the "Edit NV" box below, type 00 replacing the 01
(10) select (highlight) the item ITEM_8322 again, click "Apply changes", then "Write selected item" while item is highlighed
(10a) Check: repeat step 8 and verify it now reads 00
(11) reboot and cross fingers.
I hope this is clear enough even without screenshots, and that I didn't miss any step, but hopefully adventurous and impatient people that cannot wait for cellzealot's zip will figure it out

Of course, in case it wasn't obvious, if you flashed your phone with the Telstra radio (or any other radio), you have to flash back the original verizon radio... I'd assume that if you were able to flash some radio on it, you are probably able to flash the original radio back, but if not, I can give directions for that as well.6The zip file would be super convenient...

These directions were perfect! I flashed my radio from the Aussie radio back to the default Verizon radio.
I then changed the NV entry and BOOM! H+ data on StraightTalk (AT&T) - AMAZING! Unlimited Talk / Text / Data for only $45 bucks a month!
One thing - if you have windows 64bit OS, the driver above will not work (its only for 32bit OS) - follow these directions to get the Motorola COM Port:
Thank you so much to everyone for coming up with this solution - I was so close to pull the trigger on a DROID RAZR 1 this morning - so glad I didn't!
Next question I have - has anyone successfully gotten rid of the nagging "The SIM card is from an unknown source." messages?3I will be writing this up in my thread but will give a quick listing here.

Huge thanks to Arnold Snarb! Brilliant work!
I am currently on ATT with full HSPA+ service under the VZW modem after using DFS tool to edit 8322 to 00 as stated above.
I am also using an edited build.prop file that I have setup for GSM testing,and need to determine if those edits have any effect and also whether it works with stock build.prop and simply swapping SIMs is all that is needed to switch between normal VZW service and GSM service.
It is also possible that we can create a flashable zip for CWM recovery that can perform the NV edit without the need for a PC or Diagnostic Mode access tools.
This is really fantastic news and will almost certainly have implications for other devices as well.
Congratulations to Arnold Snarb and everyone else who has contributed to the investigation!
