[Q] Custom ROM for XT912 on GSM global - Motorola Droid RAZR

I have bought a Droid Razr XT912 to be used outside US. I understand ICS will unlock the GSM bands. My question is, will loading a custom CDMA ROM based on ICS allow me to use the the phone on GSM networks outside US? This probably is a stupid question, but I wasn't able to find any direct answer to it.
Thanks.

I pretty sure that the xt912 is the american cdma version of the DROID RAZR, so installing ICS or any other ROM wont help you with gsm bands.
the CDMA have other anthena or something.
BUT check the correct model you have.

The XT912 has GSM bands as well. I'm pretty certain after going through these forums that the ICS update unlocks the GSM bands. I'm keen on a custom ROM coz it will get rid of most of the bloatware & give additional functionality as well.

Thanks monkteo for confirming. Are u using a custom ROM? I'm inclined towards the Eclipse 1.5 but want someone to confirm it works on XT912 for GSM use.

I use all 3 rooms from the signature, and only on GSM / UMTS.

I have tried to use on GSM networks but it won't connect, and I have changed the settings a few times for the Mobile Networks. I am trying to use AVATAR ROM on the XT912. Thanks!

[Q] Raising the same question again!!! LTE on XT910?????

Sorry to ask the same question once again,but , I am just curious...
since the XT912(Verizon) and XT910 has the same hardware and chipset, I can be pretty sure they have the same radio.
Is it possible for anyone to say, whether we can activate the LTE functionality in the XT910...(maybe a custom baseband SW) or something..
I'm going to attempt to flash the GSM radio into my XT912. Everything I've also read says that the chipset should allow for GSM access, just carrier locked by Verizon.
This article has been referenced a few times about the inability to use AT&T and Verizon LTE devices on each others networks:http://www.pcmag.com/article2/0,2817,2388526,00.asp
I'll let you know if a radio from a GSM SBF or GSM Rom works on this though!
Thanks mate!!!
This is a good experiment. Waiting to see.

Hi,
Can anyone help me by posting the baseband SW of the XT912....
Help me a lot for my experiment..
I flashed the GSM radio image on my XT912 through RSD... Everything looked normal, RSD said it processed image 1 of 1, then the phone rebooted, came back up and was still on the CDMA Baseband image... Not sure exactly what happened but I was just happy it didn't brick it!
My phone is currently useless to me anyway since I'm in the Philippines. Willing to try flashing/testing whatever a developer would like to have me test at this point in time. Need to have GSM radio activated/enabled so I can use this phone... That's the bottom line I guess...

After flashing the radio, di dyou change baseband?
Let me know whether changing the baseband solves your problem, then I might try to do the inverse thing...
How do you change baseband? I'll try it if someone can tell me where/how to do it...
I have the xt910 in Canada with no LTE but the network supports LTE. I am extremely excited to see how your experiment works.
Did you ever get this to work?
Yes, I'm still very interested in this if anyone has further details. This thread is very similar, but goes the other way (enabling GSM on the CDMA/LTE devices).
This does not work and cannot be made to work. There is another additional LTE radio chip in the XT912 that is not there on XT910. They are not the same hardware, despite being very similar.

Source? I've heard claims from both sides of this argument on XDA (some say it has the LTE radio, some say it does not).
I have yet to find a teardown of the XT910, I can only find pictures of the XT912 internals. I understand that there's a possibility that Motorola didn't put the LTE radio in the XT910, but again, I have yet to see a definitive source claiming so (i.e. pictures - and again, can only find pictures of the XT912 internals...).
I noticed that Rogers advertises the xt910 as being a LTE device. False advertising?

I dont think the XT910 has any CDMA radios at all. But lets see.
The Korean XT910k has LTE according to motorola website
But it also cannot flash normal razr fastboot files and roms....
same with the latin razrs also cant flash normal xt910 roms, and it has the lte radio....
Maybe there is a link in this?
Any Latin razr users flashed the XT912 fastboot before?

Pedro, I flashed the LATAM ICS ROM to my XT910, and while it shows the option in the Phone Menu, the LTE option won't stay selected. It keeps reverting back to GSM.
I'm interested to see if someone successfully flashed a new radio file to activate the LTE on the XT910, or if this is a hardware issue, being that the hardware for LTE simply isn't inside the XT910.

Safe to flash custom ROM's?

Hey guys, im planning to buy a Droid Razr in India (the CDMA one) and using it with GSM, and the guy who's selling it says that i can flash Custom ROM's without any hassle. Is it true? Just wanted to confirm.
thanks, sid.

Motorola razr XT912 is unlocked by default in ice cream sandwich update.
You can also manually unlock it in 2.3 version too.

Since no one has responded to my request let me answer my own questions :
1) Moto Razr XT912 4.1.2 can be unlocked to be used on GSM ( am using in IND )
2) Root Exploit is also available which enables & provides you root access. ( Which is highly Easy : all thanks to those who developed it )
I liked the phone so much that bought another for normal use and one for Ubuntu

Well, yes I know you can use GSM on stock unlocked verizon's XT912 on ICS(or later), but the thing I really want to know is:
When it comes to choose a custom rom, using the cdma_spyder version, will stop my gsm working?
Will a umts_spyder version of the software brick the phone?
Actually I still can't understand the real differences between the two motherboards (I even read that putting a xt912's battery in a xt910, will make the phone think it's a MaXX)
Again, thank you kindly
As per me !

XT912 & XT910 are same phone with same chipset TI OMAP 4430. Only difference in the two is while the prior is Global Phone ( all frequency support ) later is GSM Only ( and 2MP front cam vs 1.3MP ).
XT912 conversion to Maxx is completely different. XT910 & XT912 both have same battery 1780mAH while the Maxx has 3300mAH battery.
For Ubuntu Touch I plan to have UMTS_sypder custom ROM https://wiki.ubuntu.com/Touch/Devices/umts_spyder ( at my own risk )
I won't be able to tell much, as all I am doing is on my own gathering bits and pieces from the fourm ( as no one seems to come forward with all the answers clearly. )

my understanding 912 is a hybrid qualcomm mdm 6600 ti wrigley LTE radio chipset and the 910 is a qualcomm msm 890 snapdragon Soc. that is why the american gsm unlock thread utilizing radiocomm will not work on a xt912. it will recognize the sim and number but the radio portion of the chipset is directed to pass over the american carriers. the 912 will work in europe and central america on foreign prepaid sim cards. i have one and tried it. still looking for an american gsm unlock fix for an xt912.
