***UPDATE 6/26/2012***

Ok, not all the info that I got before was 100% correct. It looks like RAZR / MAXX is unlocked only for Global(GSM) use which is outside of USA. The Tmobile and ATT sims are not fully working as of right now.

We have couple amazing Devs which are working to resolve this issue.

Please PM me if you want me to update the OP.

-----------------------------------------------------------------------------

On the Bionic forum people found a way to activate disabled feature of couple 4g verizon phones to be able to use it on GSM networks.

Can someone test it please?

Amazing...no one here has any interest in this? maybe you should have posted in the development section. This is great news if it gets working on the razr.

Actually the Bionic does have a GSM radio.
The Razr, 4, Bionic all have the same Qualcomm global radio and a separate LTE radio.

The only thing preventing the Razr, Droid 4 or Bionic from connecting to GSM is the firmware.

The Droid 4 is scheduled for GSM upgrade.

I stand corrected. Well played.

I was under the impression that we just needed the unlock code. Once we have it from say...att, then we put the sim in,enter the code and good to go...maybe its not that easy but on YouTube it looks pretty close lol.

As far as I know it's not that easy due to the fact that the GSM modem itself is disabled. Unless your talking about roaming onto the LTE network. Though ATT uses different frequencies.

I was really surprised that people did not accept this news well. I was extremely happy to hear that we can use our phones with GSM providers since I am planing to travel soon.

Yeah. No thought about lte if I had to use GSM. I feel dumb as that's the entire point of the maxx being called a global phone lol. There's a video and it is really easy to do.

this is exactly what i did and now is recognizing an at&t (old desactivated) and a tmobile sim(old desactivated) card but i need to test with an activated one. i noticed with the tmobile one a gsm networks setting appeared on my menu.

see post 29 & 30

by the way the razr needs to be running gb i was on ics leak but i didnt find any charge only mode or pc mode.

i went back to ics leak and seem to still working but like i said i need to test and activated sim card

before people start to flame im not taking credit and im not interested on any im just sharing what i did.

Okay so, here's my predicament..I'm currently using an Atrix 2 with a regular sized SIM card and wanted to test this out on a busted VZW Razr I got from work (there's a huge crack in the screen and it was just collecting dust). If I went into an AT&T store and bought a micro-SIM, would it work?
The only reason I'm confused is because all I know that AT&T uses the micro-SIMs for is the iPad; I don't know if the structure of the SIM card changes to accomodate just data, or if voice will be able to be transmitted as well.

    TBH Band Config Unlock zip Install for Razr

    It's not "Magic code".

    It is just a zip installation of the NVM edit using the updater-binary from an official OTA update.zip to write the 8 byte string for the band config to NV Item 1877.

    The NVM is updated every time you get an OTA in order to increment the version numbers and dates. We just used the binary for our own needs.

    So far, we have not had complete success with this on the D4 or Razr on stock hardware with T Mobile or ATT in the US. There appears to be a different form of lock in effect for domestic GSM carriers, because there are many reports of it working with international carriers, at least on D4.

    There is a Chinese engineering ICS build that P3droid has running on his eng Razr and everything works out of the box with that radio image. It cannot be loaded on stock hardware unfortunately.
    We dumped the entire NVM from it and I have been going through it to find a potential solution. There are many differences in the NVM and it will take some time to work through them to determine their impact.

    Edit: I have included the Razr version of the TBH band config zip files for those interested in testing this.

    These files MUST be run from Razr bootstrap recovery and NOT Safestrap.
    The unlock zip writes the GSM band config string and the relock zip writes the stock string to revert if you need to for any reason.

    They do no other modifications to the device and any build.prop edits or additional apns-conf.xml or system libs must be done manually if desired.

    Please post back with any information regarding success or failure using these files, thanks!
    The files did not upload from my dropbox properly, sorry. I will have to reattach them from PC later.

    Edit 2: I reuploaded the files. These have been tested on mine and P3droid's Razrs and should work fine.
    As people quickly discovered, the D4 files work on the Razr too, so you can use either. The binaries are compatible and the string is the same. The Chinese ICS build has a slightly altered string that you can also try in RadioComm if desired.
    The first 2 bytes are different: 8001E80400000200

    how did you do it , as in the steps and the carrier you used, att or tmo.
    assuming it's att as you are on 850 3g, also can you please post a pic for us.
    we will be so happy :)

    Actually its pretty easy , no need of Radio Comm

    I have a Moto CDMA XT912

    Steps :

    [optional] Flash this : ICS ROM > http://bit.ly/JW8j8w
    [optional] Flash this : GAPPS > http://bit.ly/JW7vAG

    Flash this : GSM PATCH > http://bit.ly/JW7Hjd
    FLash this : "MAGIC code" lol > http://forum.xda-developers.com/attachment.php?attachmentid=1048524&d=1336485537

    Reboot , and done ! , you'll have GSM enabled [ all bands ]

    I am not giving up anyone. Right now still working on unlock for xt912 for my wife since she hates changing phones. Can't ask for anything better then a phone that can do both CDMA and gsm. We are planning a trip to Asia after the baby is born.

    From what I've gone through so far I can't seem to find anything in particular in any of the nv items that jumps out. I've tried comparative with a SIM card, without, all kinds of ways. Something that was brought to my attention is that even though this phone has the same radio chip, it has a seperate Lte on chip that the other razr's don't. I've found where in the bp.img the us frequencies are blocked. But it's not as simple as overwriting or rewriting the values as that still breaks the signature on the expected filesize check. I also found a value table when going through the mmcblk1 pull and I'm going to see if I can use that to manipulate the bp.img file. Who knows. Just finished my school reports so I got some free time tonight and tomorrow night. Anyone who's up late can through me a google+ chat "queberican351"

    Oh, and the bp.img does reference 0F as a trigger for the 255 (Network ID) and 65535 (System ID) block. Maybe that's somewhere to start. But there are ALOT of locations in the NV dumps containing 0F

    This is the values table I found. I don't know that it'll help us but anyone who knows a lil sum'n sum'n to do with this here you go.

    0 = NULL
    1 = 38.4
    2 = 76.8
    3 = 153.6
    4 = 307.2 short
    5 = 307.2 long
    6 = 614.4 short
    7 = 614.4 long
    8 = 921.6
    9 = 1228.8 short
    A = 1228.8 long
    B = 1843.2
    C = 2457.6
    D = 1536.0
    E = 3072.0
    F = VarRateNonOverride
    10 = 460.8
    11 = 614.4 (4slot)
    12 = 768.0
    13 = 921.6 (4slot)
    14 = 1075.2
    15 = 1228.8 (4slot)
    16 = 1843.2 (2slot)
    17 = 2150.4
    18 = 2457.6 (2slot)
    19 = 3686.4
    1A = 4300.8
    1B = 4915.2

    I also found that NV_ITEM_8044 listed Unknown acts as an NV-READ_COUNTER
    Every time I read it's value the 2nd byte goes up 01,02,03 progressively.
