It's not clear yet what they are doing and on the Bionic under ICS, it shows no signal or 120 -dbm and there is no phone number showing in Settings/About/Status but nonetheless calls and text work. P3Droid said he had thought it was working on his Razr as well, with similar broken aspects on the .211 release, but I can't repeat it on mine.

He also has been able to get 3G data on his Bionic on the 2233 ICS build as well, and so far his success is an anomaly which neither of us can figure out.

So, I may have misspoken regarding calls and text on the Razr, but it does, in fact, work on Bionic under ICS despite appearing to not be able to read the SIM.

It does display ATT on the lockscreen and in the Phone Information menu it shows network type as HSPA.

I do believe it is an MNC lock or flag that is the trigger, but what precise action is initiated in the radio is still not clear.

Ok so ive done the following and herea what i got..stock verizon razr xt912..all i did was the nvedit in radiocomm..and using phone info..readd my sim..reads number..recieves texts and voicemail alert..using tmobile sim..shows apn and settings..no call text or data
[Motorola Droid RAZR] d4vr0s:
I'm going to Germany in the next couple weeks, and am hoping for a definitive answer to whether or not I can use a prepaid sim, such as Simyo with my Razr Maxx while I'm there. Also, whether or not I'll need some unlock code in order to use it. I'd love to use my phone, but don't want to pay verizon roaming fees.
[Motorola Droid RAZR] jeanpijon:
Is there any possibility to help cellzealot and the others with examining VZW blocking process on actual ICS?

So far, I noticed, that after turning radio on and off, for a few moments, I can see Cell ID in Network App. So it really seems, that there would be a conditional lock on NMC. But, this behavior led me to another thing - if there would be this lock on the deep HW layer, you would never see CellID in the application on the top of the system. So there might be a possibility that this lock will be somewhere higher than on HW Layer and if that is true, there is still a hope...
[Motorola Droid RAZR] mc732:
Yeah it must be pretty high up to be able to connect at all. I wish I knew more about android. I'm learning but not fast enough for my taste.

For the record you can telnet into the modem and see ATT and T-mobile networks. The command to connect to them is successful but I guess the phone disconnects immediately after.

There's a GSM patch in this thread that uses what I'm assuming are the xt910 ril libs so I'm guessing its not the ril doing the blocking?
[Motorola Droid RAZR] jeanpijon:
Can you send me a details how to connect directly to the modem?

Thx
[Motorola Droid RAZR] mc732:
I used this software to connect:

http://www.chiark.greenend.org.uk/~sgtatham/putty/

Choose bp tools from the fastboot menu to boot the phone up with com ports. Go to device manager under modems and find "Motorola QC BP Modem." Look at properties to see which com port it has.

Choose "serial" in putty when it starts up and put in that port.

Go here for some commands:

If you want to mess around with that here's something fun:

I don't think any of it is useful for this purpose though.
[Motorola Droid RAZR] mc732:
I notice in the output of "logcat -b radio" the following two lines are in there a lot:

RIL-MX : Ch0 > 0867AT+COPS?

...

RIL-MX : Read Ch0 << 0867+COPS=0,,,

From what I understand the only thing between the RIL and the chip itself is the baseband software. So for COPS? to be returning 0 the baseband must be filtering out the US GSM networks... If I'm reading and understanding all of this correctly..

guys: if a buy a droid razr from vzw with a BAD ESN, can i get the ICS OTA update? i will able to put ics if idont get it by OTA?

[Motorola Droid RAZR] :
Access Point Names detected

The Verizon Droid Razr is reading the US-AT&T GSM/UTMS Access Point Names, but it won't allow the sim to register AT&T's network. Please figure this out developers. I love this phone :)
[Motorola Droid RAZR] cellzealot:
Believe me, I am still working on this. The APNs are in the /etc/apns_conf.xml file along with many others of course, so that isn't the problem.

It's a block on the MCC, that much seems fairly obvious, but how that flag is set and by what mechanism it disables the radio is the critical question.
[Motorola Droid RAZR] :
Thank you for researching it. I cant wait for a solution. Much love :)
[Motorola Droid RAZR] macguy25:
I've actually been looking into this myself and I tend to agree that the MCC is being blocked by the modem firmware or one of the library .so files. I want to be able to use Verizon for work calls and when I get home, swap the sim card with my AT&T phone so I don't have to forward calls. I keep separate phone books and want my outgoing caller ID to reflect being on my AT&T US domestic phone.

@CallZealot - Have you tried loading a Razr with the EU or CN version and seeing if it allows US Domestic use? If I didn't need to use my phone everyday and could afford down time I would try this myself.

AFAIK the Gevy Sim for iPhone got around this very issue for some users by tricking the phone to think it had a different country code, but I haven't used it so I cannot verify this.

We should look in the firmware for code that relates to "what happens" upon SIM insertion. That MUST be the issue. Insert SIM > Verify Country Code does not equal 310 > Connect to Network, ETC.

The first step is to load the EU and CN radio onto a US phone and see if that solves it. If it does, then drill down to the piece of code in firmware that allows for this. If not, then continue the search into the .so files.

As a side note, I wonder if we DID get the US bands to work, would it be network optimized for AT&T 4G? Wonder if it would be crappy data speeds?
[Motorola Droid RAZR] kshah:
Droid RAZR MAXX, XT912, with OTA update of 6.16.211 (ICS) GSM is unlocked for non US frequency (as I know) but CDMA EVDO is blocked without LTE SIM. Is there any solution for that?
[Motorola Droid RAZR] :
As I understand it, the GSM US bands/frequencies are compatible with the GSM/CDMA hardware (not sure about 4G LTE). You can even check out the verizon website to confirm. This is ostensibly a software lockout to block other US domestic carriers. Correct me if I'm wrong.

I cant wait for Google to become a service provider. Its inevitable I feel.
[Motorola Droid RAZR] :
There are devs looking for a solution. Its only a matter of time. I'm stuck using VoIP for the time. Thanks to Google Voice, texts and voicemail aren't an issue.
[Motorola Droid RAZR] droidxrooting:
Hey cellzealot if verizon unlocked one phone for you. Could you reproduce result and maybe find a fix for all of us?
[Motorola Droid RAZR] cellzealot:
To answer your question, yes it is possible to get a different CDMA operator to work on the Razr.

Unfortunately, I don't have any way to test this and make the the data authentication configuration properly, but the following screenshot of QPST shows the MIP profile edits I made are showing up and stick after a reboot.

To answer the question about whether I could replicate a configuration from a device that VZW unlocked, the answer is probably yes, except that I do not believe VZW could or would do such a thing. Motorola certainly could, but VZW does not have the ability to do this on their own, nor do I believe they would if asked.
[Motorola Droid RAZR] :
I have an AT&T sim in my Razr. I just received a bunch of text messages last night although it clearly stated I had no signal and that the sim was from an unknown source. Anybody else experience this?

I was wondering if anyone checked the differences between gingerbread and ICS to see if they could isolate the location of some of the changes. Just a thought.
[Motorola Droid RAZR] kshah:
@ cellzealot

Thanks, EVDO Amd MIP profile stick, problem is despite having perfect EVDO and mip configuration. Phone do not connect to data. Field trial screen also do not show any error or any thing which can say why it do not connect to EVDO.

I have not seen but got the confirmation that putting in LTE SIM connect phone to EVDO. Will post once I get lte sim.

Another thing is when build.prop is edited, phone shows prl, min and mdn in about - status screen.

Droid razr Maxx also can be used for voice and text using CDMA sim. (RUIM) however using CDMA sim data do not work.
[Motorola Droid RAZR] joshw0000:
@cellzealot

I hate to derail this thread but I picked up a Droid Pro running 2.3.4 (4.7.3 system) with the intentions of unlocking for AT&T. I found a zip file you posted that unlocks on 2.2 (2.26.2 system). I sorta doubt I can sbf back that far but I plan to try. Is there anything more current or was development dropped after that release. I saw some discussion about making a flashable radio for GB which would allow the unlock but couldn't find any development on it. Who better to ask, then the pioneer himself? Thanks in advance for any info!
[Motorola Droid RAZR] evanscnce:
So, without scrolling through this whole thread as I've already searched through too many to keep reading right now, can the verizon razr maxx be used on a US GSM network like straight talk?

Trying to get it to work on a prepaid service and this is the closest I have come to finding an answer!

Thanks
[Motorola Droid RAZR] cellzealot:
No...it doesn't work. Get a Bionic instead and leave it on the .905 GB release and use the band config edit and it will work perfectly on US GSM carriers.
[Motorola Droid RAZR] :
No

Not at the present moment.
[Motorola Droid RAZR] cellzealot:
Sorry missed this post.

This is really a separate question that should have its on thread in the proper forum, but the answer is that it should be possible to do.

There are methods for doing this on the D2G and files created by Skrillax_CZ that allow reverting from .629 to .330 using repacked SBF files with the cdt.bin from .629. This loads the band unlockable radio and you then flash forwards using Linux and sbf_flash, which does not flash the radio partition, leaving you on 4.7.3 system with the old baseband.

This method would require similar repacked SBF files for the Pro, which do not exist yet that I am aware of.

Skrillax_CZ has posted the tools he used but not the precise method for creating such file, I believe.
[Motorola Droid RAZR] joshw0000:
Thanks for the explanation. I was afraid nothing currently existed. Guess I should have researched a little more before getting the Pro. Again, thanks for the info.
[Motorola Droid RAZR] joshw0000:
Cellzealot,

Another member has data (temporarily) working on Verizon Razr on AT&T - http://xdaforums.com/showthread.php?p=29669130. Maybe you can get some info from him to help you determine what is or isn't happening to his device.

Does this really work?

Does this really work fully on a Droid 4? Say, if I wanted to flash a .219 stock ROM, to make my phone completely stock?

Unlock My Device

Motorola has an official website dedicated to unlocking bootloaders. I'm not sure if this is relevant here, but it mentions the Motorola Droid Razr. Here is a link
[Motorola Droid RAZR] joshw0000:
It's the dev Razr. None of the currently released devices (except the 4 mentioned) will be unlocked.
[Motorola Droid RAZR] :
Ok thanks. How I wish this phone would work on ATT :/
[Motorola Droid RAZR] mc732:
I wish this thread could be banished. The title taunts me with it's promises and most of the content is newbish questions that don't belong.
[Motorola Droid RAZR] Morlok8k:
So i was looking in a few sqlite databases on my Droid 4, and noticed that in:

Phone/Messaging Storage (com.android.providers.telephony) / operator.db

In the GSM sections, it has a severe lack of anything AT&T and T-Mobile related.

How does it compare to the bionic GB version that works?

(Now, I don't know if this data is updated when adding a new GSM sim card, as I've never put one in yet.)

(Oh, btw, com.motorola.android.providers.settings has a lot of interesting settings - especially ones with cryptic names. it would be interesting to do a comparison with this and the bionic's copy.)

EDIT: I guess i should mention that in com.android.providers.telephony / telephony.db, AT&T and T-Mo are listed - but this just seems to be the built-in APN settings

--------

Also, While its probably been tried (or hasn't because its impossible for some reason - maybe signed), I have yet to see this question asked:

The bionic, the razr, the droid 4 all have the same chipset. can we get the working baseband from the bionic and flash it on the others?

(At least do a comparison between them?)

--------

I've been watching the progress of this for a long while now.

It's frustrating to see the bionic completely open, and my droid 4, with the same chipset, locked down.

Anyways, Just trying to give out a few specific ideas here.

I'd do the comparisons myself, but i dont have a bionic.

Edit: Seems like some progress is happening here: http://xdaforums.com/showthread.php?t=1297714
[Motorola Droid RAZR] badfrog:
ok, I have a rooted bionic on .902.

I used radiocomm to do the unlock for the GSM bands.

am I missing anything else? too many contradictions and useless info in these 36 pages to tell.

I leave tonight for Finland and then to France, was hoping to get a SIM card in one of those places to test this.
[Motorola Droid RAZR] cellzealot:
Well, this is a Razr forum and there is better info for the Bionic on that forum.

You will be fine, except for 900-1800mHz 2g GSM service reportedly does not work properly on the Bionic.

3G HSPA/WCDMA works well.

I do not have any personal experience and am just going by the many user reports in the Bionic on T-Mobile thread from international users.
[Motorola Droid RAZR] Lekan Adeyeri:
Cellzealot I have to questions

One:Will flashing a custom rom such as cm9 make it domestic gsm work

Two:Will your post "TBH Band Config Unlock zip Install for Razr" work on the official stock ics.

http://xdaforums.com/showpost.php?p=25967009&postcount=118

Thx
[Motorola Droid RAZR] cellzealot:
No, a custom ROM will not make domestic GSM carriers work because all of this is happening in the radio not the ROM.

The band config edit performed by that zip file is not needed under ICs because it is already there by default to support global service.

We recently found a way to enable domestic GSM on Bionic under ICS with a set of build.prop edits but the same edits performed on D4 do not work and have the same symptoms as we have been seeing. The MCC/MNC block is still in effect in the radio on D4/Razr/Mass.

US GSM Radio disabled

Thank you for your hard work. Hope that you or someone could find a fix for this soon as I love the Droid Razr Maxx and now use Straight Talk SIM.

I am getting same kind of issue like everyone is reporting = no signal.

What is strange is if I leave the Radio to LTE/CDMA with the Straight Talk SIM it does not show RED Circle around the radio but no signal but it does recongnize the MDN, however when making a call, it states that no valid FDN available.
[Motorola Droid RAZR] ValtheBatman:
If you go to the Motorola unlock code official website, you will see that the new phones, but developer ones are able to be unlocked.

STILL INTERESTED IN UNLOCKING THE BOOTLOADER?

First, confirm that your device can be unlocked

Currently, Photon Q 4G LTE, and DROID RAZR HD and DROID RAZR M Developer Editions can be unlocked.

For a complete list of supported devices, see What devices are supported by the Bootloader unlock program?

Hopefully the Droid Razr Maxx HD will be one of the unlockables too, but besides that hope, will this mean that it potentially will be possible for the phones to work on the GSM networks at the US?
[Motorola Droid RAZR] igwtapc:
Found a new screen that might help.

Turn the phone off while on the charger

Press volume up and down before the battery charge screen

You get a weird boot screen with SPF flash.

The phone will not stay on it long.

[Motorola Droid RAZR] igwtapc:
My system running Ubuntu 12 saw it as a qualcomm modem using BP tools. Got a pic of the screen using my razor xt912. If it is not connected in so much time tten the phone just boots as normal. I am not well versed in cellphone programming.

Tried my friends at&t sim from iPhone and got text message but no phone calls or data. Can someone point me to a way to decompile the phone itself that would be great. Have some ability to write code but still noob on android.
[Motorola Droid RAZR] igwtapc:
maybe going in the wrong direction

I got to tinkering in my razr yesterday and got it to pickup cricket service by ##program without any major changes. When I try any GSM sim cards the phone still seems to use cdma for its main communication. If I had a frequency counter then I could verify this is true. Got a friend at cricket to temp activate my phone and the data was even 3g. Maybe somewhere there is a line of code to prevent someone from just sticking in a sim and using the phone on another carrier. I am curious if anyone tried to put the xt910 rom and radio on the xt912 and see if that is the fix for the GSM.
[Motorola Droid RAZR] TSRV1:

Want to contribute

Hello friends,

I've been watching this thread for about a week and it looks like not a whole lot of progress has been made in unlocking the GSM radio for domestic (US) carriers on the Droid RAZR / MAXX. I have an XT912. I am a bit of a noob on the droid scene, having installed CM on my old Droid, but nothing else. However, I really want to unlock this phone, as Verizon royally F'ed me in the A on my bill last month. I'm a software developer by trade and I believe I can help. God knows I am willing. PM me if you are working on this and you think another hacker can be of use. Also I want to say thanks to everyone who has been working on this, it's been an interesting thread to say the least.
