[Droid RAZR M Q&A, Help & Troubleshooting] Artifesto:
Are you saying you cannot unlock it? The unlock process does work but it took a few tries for me. I have had a locked bootloader and took every OTA update without root and following the steps here I successfully unlocked my phone and am now using it on a GoPhone plan (which for me was most appealing due to lack of service or price of other providers in my area). I have not had any issues, I tried all three methods listed here and finally got the unlock to stick by using the first and third method back to back several times before restarting. After completing the NVedit more than a few times it stuck and the only message I get now is on a restart my phone will say the sim is from an unknown source but after 2 or 3 seconds it connects to AT&T and I have had fast 4G without any issues all day.
[Droid RAZR M Q&A, Help & Troubleshooting] ShadyDreamer:
What I've seen and what some others have seen is that you simply need to wait some time before restarting and the setting will stick. Trying it several times before restarting probably just takes enough time to do it that you've waited long enough before restarting.

Gone after OTA Update

I just received an OTA update to Android 4.4.2 on my Motorola xt907 (183.46.10) and it is no longer GSM unlocked. I came straight from 4.1.2 and everything worked perfectly. I unlocked the phone for GSM use, by using the RadioComm method. When I did that unlock, I also had to use the Test Menu on the phone by using *#*#4636#*#* and switching the network mode. However after the 4.4.2 update, I'm not able to get into the Test Menu at all or any other menu accessed through the Dialer, it just goes back to the most recently called number. The network mode in Mobile Network Settings was switched back to Global Mode, so I switched it to GSM/UMTS (Global worked for my GSM while on 4.1.2), and I had a couple bars or service for about 45 seconds and then it disappeared. I went to go search for networks and it came up with an error every time. My last resort was to go to RadioComm and try that again. I did everything the way it was set up before, but when I typed in the Decimal value of NV Location "8322" and then "1" as the byte length, there would be no "01" that would show up in the Hex and the numerated box above turned to red, where it turned to green when I unlocked on 4.1.2. I tried this on two different computers, including the same RadioComm that unlocked my phone in the first place. I'm really not sure where to go from here, as this is my only phone after my Samsung GT-N7000 went into a boot loop. Any help on how to get a Motorola xt907 re-unlocked after the 4.4.2 update would be greatly appreciated. Thanks!

Update: I used the STELEM/RDELEM method and it seems to have worked perfectly, I am now running H20 (AT&T) on the xt907. Thanks for that last method cellzealot, much appreciated!

no deep sleep after KitKat upgrade?

No problems with the NV unlock or update but my phone has suffered overheating, random reboots and terrible battery life only when connected to 3G HSDPA on AT&T/straight talk. Apparently there is a fast dormancy bug that prevents the phone from going into deep sleep mode while connected to 3G. Before I give up, I just wanted to check and see if anyone has an unrooted xt 907 running KitKat on AT&T without these issues. If you don't see any deep sleep time in CPU Spy after a few minutes with the screen off and 3G connected, you have the same problem. On the other hand, if your phone gets some sleep, maybe mine can too.
[Droid RAZR M Q&A, Help & Troubleshooting] cellzealot:
There is a solution that requires root to edit the build.prop and it is possible I could find a corollary solution via NV edits but that will take some work to isolate the NV Items and parameters required.

I will look into it but it won't likely be quickly discovered.
[Droid RAZR M Q&A, Help & Troubleshooting] AndroidMilos:
Thanks OP. This method worked great for me. I upgraded to 4.4.2, did the NV mod (twice actually) and put my TMO sim in and I get HSPA (+ sometimes too). I have seen download speeds so far up to 10mb!. When I did the NV mod, I think the whole secret is to leave the razrM alone and plugged in for another 10 minutes before disconnecting and using the device as this is what I did the second time I did the mod.
[Droid RAZR M Q&A, Help & Troubleshooting] mui.kathy123:
Hello guys. I am new here and would like to ask some questions as I am unsure whether or not I did this correctly for the xt907.

For the usb drivers I used this website to download them:

motorola-global-portal.custhelp(DOT)com/app/answers/detail/a_id/88481

(I can't post outside links yet apparently)

Is this the correct step for the driver installation part?

I followed everything on the OP with radiocomm and successfully changed the hex value to 00 and did a second read to get a hex value of 00 as well.

I currently have a regular size sim card for att and the xt907 has a verizon micro sim card in it. Using the verizon micro sim, I changed the mobile network type to gsm/umts, I get a message that it cannot find or detect a gsm/umts network although I do get regular att service in my area. Do I have to have a att micro sim in order for it to pick up att's signal? I'm asking because I don't have an att micro sim yet. I'm planning to get a cutter if I did do this right.

Please don't say cut your att sim and put it in to see if it works that's not helping...

Thanks
[Droid RAZR M Q&A, Help & Troubleshooting] theskinny:
Yes, you need att's micro Sim to register on att's network.

If you received the 00 hex you should be good to go, I've been using att on an xt907 and 926 since this with no problems

Exact same problem.

Unrooted, kitkat, straight talk AT&T 3G = no deep sleep, random reboot, occasional lost of signal.

This is pushing me to get a new phone.

EDIT: DID YOU KNOW STRAIGHT TALK HAS LTE SIM CARDS? Just placed my order with StraightTalk (Free Overnight Shipping). Last chance before I move on to different phones.

EDIT: btw this appears to be a Motorola QC issue with Kitkat. There is a huge thread going on Motorola forum as this is happening to all the moto device on 3G.

[Droid RAZR M Q&A, Help & Troubleshooting] rmg512:
Thanks for the reply. Good to know I'm not the only one and I am also considering a new phone. As a patch, you can download an app simply called "Network" and use it to select GSM only. This limits you to 2G speeds but at least you get a working phone. I have an AT&T LTE SIM card from Straight Talk. I ordered one before I did my research and I don't get LTE. Despite being on the same frequency, Verizon and AT&T LTE are not compatible.
[Droid RAZR M Q&A, Help & Troubleshooting] l3536:
You are right none of the Verizon "droid" phones can support both LTE and GSM at same time. I guess it's time for new phone (LG Optimus G Pro maybe?) since I really need the data.

Thanks a million, CellZealot!!!!!!!!!!!!!!!!!

Originally, I did the hack on JB 4.1.2, and was happily using Straight Talk / ATT. However I was initially panicking when I could not call or text after the KK 4.4.2 update on my Razr M!

However, after I read the experience of another user who had the same symptoms I did, and the update said they had used the STELEM / RDELEM method, I tried it and it worked like a charm! Perfect first time!!!

Thank you, thank you, thank you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

http://xdaforums.com/showpost.php?p=52960161&postcount=654

Here is a response from another thread that shows the build.prop edits needed for some of the bugs.

C+P from myself:

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.

every time i boot the phone in the boot menu it resets the settings. when the phone comes back on, media device and USB debugging are disabled again. Am i doing something wrong?
[Droid RAZR M Q&A, Help & Troubleshooting] flipinfin:
How do you enter this mode ?
[Droid RAZR M Q&A, Help & Troubleshooting] cellzealot:
I am not sure I understand the question.

This is another way using RadioComm with the phone booted in Factory mode like the prior methods in this thread.

You scroll over to the P2K4 tab to use the STELEM/RDELEM window in that tab as opposed to the FTM Common 1 tab.

Does that make it clearer?
[Droid RAZR M Q&A, Help & Troubleshooting] flipinfin:
Yea thanks i figured it out. I did exactly what you said though it keeps telling me no gsm/umts not found. Unlocked worked perfect before the update. any Suggestions. Cant i flash the 4.1.2 radio. You have a downwload link ?
[Droid RAZR M Q&A, Help & Troubleshooting] cellzealot:
I don't think the older baseband is compatible with the new 3.4 kernel and RIL but I am not certain. I don't advise trying to use the 4.1.2 baseband nor should it be necessary.

Something else is wrong and needs to be isolated. The hack works exactly as it did before and I ran it under at least 6 versions of KK and had only to reapply the edit each time.

I also recommend getting an app from the play store called Activity Launcher and using it to set a shortcut to the Phone Information menu in settings.

This will allow you to access the hidden radio settings menu to manually select the operating mode.

One of the bugs in KK is that it resets the mode to WCDMA Preferred from GSM Auto PRL and causes it to lose signal requiring reboot or resetting the radio to work again.
[Droid RAZR M Q&A, Help & Troubleshooting] flipinfin:
Do you just know the the ussd code from dialer ?
[Droid RAZR M Q&A, Help & Troubleshooting] cellzealot:
Activity Launcher does not require root so I recommend starting there.

You will continue to have difficulty with this hack under KK without root due to the modem fast dormancy bugs. It causes a variety of issues that can mostly be solved but only via build.prop editing unless those parameters can be isolated in the NVM and edited that way. That is a much more complicated solution and may not be possible even.

The hack itself works in the radio just like it did before but the /system components need a little tweaking to remove some of VZW's optimizations.

[Droid RAZR M Q&A, Help & Troubleshooting] Germanese:
Just a tip.

There are three 4.4.2 for our phones.

Depending on which version you have updated to some things may not work correctly for use with GSM.

official 4.4.2 build 10.1 <--- Radiocomm + Build.Prop = Working GSM

official 4.4.2 build 10 <--- nothing worked

unofficial 4.4.2 build 10.1 <--- Radiocomm = Working GSM

unofficial + GPE <---- Radiocomm + Build.prop = Working but crashed alot

official 4.4.2 build 10 + GPE <---- GSM didn't work no matter what i did

My phone had issues going from unofficial to 10.1 official but after removing get var out of the xml I was able to go to 10 and then 10.1

So my process was unofficial > official 10 > official 10.1 > GPE (Stripped down Kit Kat) > build.prop > Radiocom

Happy camper now =)

Thanks guys =)
[Droid RAZR M Q&A, Help & Troubleshooting] ShadyDreamer:
Those of us with locked bootloaders on the Razr M, HD, and Maxx HD can now apply those build.prop mods on Kitkat, due to the recently released Kitkat root exploit: http://cleanimport.xda/index.php?threads/2783912/

Apparently the Kitkat update for these phones also reverts the fix for the bootloader unlocking exploit for some reason, so once rooted you can also unlock your bootloader with the old exploit, to make sure you will be able to apply the build.prop mod in future updates (and get root if you want it).

There are, indeed, many different ways to manage all of these modifications and users should use whichever they are most comfortable and/or familiar with. I was only providing the method I use and the most direct and simple one to explain.

I am sure there are other things in the OS that can be tweaked via various tools and methods to improve performance on GSM/WCDMA carriers as well and I wholeheartedly support anyone who finds such tweaks to post them here so that everyone may benefit and learn.

[Droid RAZR M Q&A, Help & Troubleshooting] rocketrazr99:
Yeah, you perform the NV edit and will get H and H+ data speeds, but the edit is to make the GSM capabilities work in the U.S. as well as globally. LTE will NOT function for the GSM carriers in the U.S. though, it only works on the VerizonWireless network AND their prepaid bands, which supposedly is 3G only, but they are aware of this and will blacklist your device if they find out, which they won't unless you more or less tell them. So call them asking why you get LTE on prepaid Verizon, lolol!!! Search "RAZR M GSM NV edit" for the procedure, it's very easy if you have even only basic experience with customizing cell phones. The XT907 and XT926 are both capable of this edit and with very little effort can be transformed into GSM devices. And the edit can be performed on unrooted, locked handsets, although I have yet to confirm with a unit updated to Android 4.4.2. Just be sure it sticks. If you have success please let it be known on XDA as I have yet to read of it. TY and good luck! :)

PS: 2G should just work if there's not a 3G signal in the area. If not maybe do some research into another APN to try. Keep trying until you hit on one.

An update to my previous post. I get data when the phone shows Edge and H+ connections, but when it shows 3G, I don't get any data connectivity. The data icon will even be blue, but nothing comes through until it changes back to one of the other connection types. I've done the following build.prop edits:

ro.mot.phone mode.vzw4gphone=1 change to 0

ro.mot.ds.fastdormancy.disable=false change to true

telephony.lteOnCdmaDevice=1 change to 0

I've also frozen the basic VZW bloatware and the system updater, and I've renamed VzwPhoneService.apk and .odex to prevent the unknown sim popup.

I'm on prepaid TMobile in Portland, which has been nearly completely refarmed. I'm not really sure what's up, as my sim- and GMS-unlocked Droid 3 got 3G here just fine. I've tried changing the network settings to GSM only, WCDMA preferred, and GMS auto.

Is anyone else here using the Razr M on TMobile in a refarmed area? Any similar experiences?

Is the phone still active with Verizon or configured for Verizon in any form? I never saw a 3G indicator on GSM/UMTS, only G, E, H, or H+.
[Droid RAZR M Q&A, Help & Troubleshooting] ezdi:
I'm on KK in a tmo refarmed area. 3G works fine. 2G works (but slow enough to be useless). It worked on JB also (even used it in Pittsburgh back then). For KK, I had to manually add the APN or I would only get an upsell message for tethering, but I don't think I did anything relevant beyond what 5318008 did.

Guesses: I froze com.verizon.permissions.vzwappapn, vzwapnservice, maybe vzwsecuresettingsapp is relevant.

On JB, sometimes if I switched radio modes outside the regular settings app too many times (scripts,etc), the GPRS connection would sit on "connecting" or "connected" but the status bar wouldn't show any data connection and I got no data through. I solved it by rebooting (sometimes hard reset, power+vol-down), switching preferred network type between all three settings in the regular settings app (sometimes leaving it on global, sometimes back to GSM/UMTS), or both in different orders. There never seemed to be a particular fix that would always work. I just had to keep beating on it. Haven't tempted fate yet on KK, though the *#*#info#*#* menu in inaccessible though the dialer (can get at it with custom shortcuts to the activity though).

5318008: Are you on KK? How did you switch modes? Are you sure they actually took? On JB, attempting to set WCDMA preferred would do nothing. This would happen either using the "secret" phone info menu or GravityBox. Sick of my phone hanging out on useless 2G when 3G was available I tried scripting to force it to "WCDMA only" sometimes, but my data would get hosed once or twice a week and not work until I fought with it as above.

On an old phone I had, if you changed the band settings, you'd sometimes break something in the radio or RIL and get a brick or no signal until you did a full factory restore.

---------- Post added at 12:55 AM ---------- Previous post was at 12:43 AM ----------

I have seen 3G on a number of phones, including my M. I believe it shows up when you're on UMTS, but not HSDPA (I doubt that exists anywhere), and also if you're connected on HSDPA(+), but haven't sent/recieved any data yet. In HSDPA, the radios fall back to some low power UMTS mode when data is not active. This is why speedtest (and similar) give you terrible ping times on HSDPA (the radio needs to switch modes before communicating).

If my phone boots up in range of WiFi, it will actually say 1X (a CDMA mode which I can't actually get on with a tmo sim) until I disconnect from WiFi. Maybe it's a bug because of some stuff I did with GravityBox, dunno, don't really care.

[Droid RAZR M Q&A, Help & Troubleshooting] 5318008:
I don't think so. The person I bought it from had already gotten a new Verizon phone that they were using on their current plan. In the screenshot I added, the 3G icon is clearly visible, along with the message in the browser indicating no data connectivity.

Per my original post, I'm on JB 4.1.2. I actually did a factory reset about a week ago in response to an unrelated matter. 3G gives no data, before and after the reset. I was hoping to put off upgrading to KK, based off of mixed reports people are giving on the M performing better/worse after the upgrade. I've accessed the band preference settings through the dialer shortcut, and also through the Network app from the store. I'll also toggle the data off and on when changing those preferences. The settings stick, but still no data when 3G shows.

If I try the upgrade or another reset, I'll report back. I just wasn't looking forward to having to set all my apps and prefs up all over again. Thanks for the advice and help.

[Droid RAZR M Q&A, Help & Troubleshooting] 5318008:
I don't really make many calls so I'm not sure about that. I mean when the data connection icon in the status bar is E or H+, I get data, and when it's 3G, I don't. I'm sorry if that's not clear enough, I don't know how else I can state it.
[Droid RAZR M Q&A, Help & Troubleshooting] Zeljko1234:
OK, seams that your phone can attach to 3G (otherwise you'll not get that icon). But it cannot create or maintain PDP to APN. That's strange. Next time check voice call or SMS (better both) on 3G. Also find proper settings for you carrier APN, erase old one and create new one again.

That's make more sense. APN is not related to calls or SMS, only for MMS (usually special APN for that).
