I don't have even the slightest knowledge necessary to be able to contribute to this conversation but I do know that I am planning to go out the country for quite a while and would love to be able to connect to a wireless data service of any kind. I will be in a country with cdma also but of course it is not verizons.

If what you are trying to do works I would happily try to donate something out of appreciation. The idea of my xoom working with gsm networks would be more than a dream come true. I wish you all the best. Let me know if there is anything I can do (I know there isn't though, I really dont know the first thing about modding other than that the modders are awesome!)
[Xoom General] GhostOfTheNet:
Good Morning,

There is something confusing me, and it seems I've to think about something I cannot imagine actually.

So my big stupid question:

Do you need a simcard to connect to verizon's cdma network?

And if not, how are you athentificating in the net?

Regards

Ralph
[Xoom General] kcrudup:
CDMA authenticates to its network via the combination of the MEID (formerly known as "ESN") and the MIN, both of which are hardwired into the firmware of the device.
[Xoom General] GhostOfTheNet:
Ok, so the device is authentificating, but from where do the network know that you are user xyz? In gsm networks because of the simcard id, and in cdma nets?
[Xoom General] kcrudup:
They associate the MEID/MID/MIN to your account.

For example, they scanned the barcode from my Xoom when I bought it and added it to the Verizon account they had already finished setting up for me. Once I got it home and hit the "Activate Device" button, the device got on the VZ network, where the setup information (the phone number, PRL, etc.) got downloaded to the CDMA 3G radio. But all that happened 'cause the VZ servers were already set up to associate that MEID to me beforehand.
[Xoom General] GhostOfTheNet:
ouch, that means there is a massive firmwaremod needed so that it can use the simcardslot for auth... :(

ok, please tell me what you know about how transfering the data from the sim to the chip works (bookmarks and so on)

do the ril-daemon play a role?

thanks

[Xoom General] IndivisibleP:
Now no sim card is used to connect to Verizon's 3G network. The new 4G Lte network will use a sim card, but that has yet to be activated. At present you connect to Verizon's 3g network through the cdma radio which needs to be registered and then activated by them, but it does not use a sim card.
[Xoom General] chaoscentral:
The sim card slot is a dummy slot right now, there are no electronics in there that can even read a sim card right now. When you send out the Xoom for the LTE upgrade they will put a real modem in there with the sim card slot. It is PHYSICALLY IMPOSSIBLE to convert the Verizon Xoom to GSM at this point in time.
[Xoom General] freemsk1:
post to delete
[Xoom General] cellzealot:
Key words: "...at this point in time."

That may change once the hardware is in place for the SIM slot it MAY be possible to build a radio image that can access GSM/HSPA bands.

Not easy, but not impossible. ;)
[Xoom General] Bauxite:
You would also need to modify the antenna to pick up the correct frequencies, they usually aren't on the same band as CDMA. For example VZW is the only carrier going for a total 700mhz 4G network.
[Xoom General] kcrudup:
That's almost correct. There's a working, active SIM-card slot that's hooked up to a serial port on the CPU; reading a SIM card right now would just be a matter of some (extra?) software. What's physically missing is the actual LTE modem, and there's a dummy card in the mini-PCI slot right now.

But that's not why it's not possible to turn the current device into GSM; as noted in this thread before, there's a lot of other things that'd need to be there, and just 'cause the 6600 is GSM-capable doesn't mean it's a simple, software-only modification. Even if it were, good luck getting the customized baseband software from QCT for it.
[Xoom General] GhostOfTheNet:
Ok, lets collect.

Mdm6600 is capable of gsm/umts

The sim cradslot is from hw side working.

The antennas... what means rx diversity in all bands?

Can be from hw side something else in the way?

Is something in the way if I plug a mpcie modem into the slot for the lte device? Have one at home, have the driver and somewhere in this forum is the source of a kernel.

[Xoom General] GhostOfTheNet:
Updates guys:

1.) with euro system image, the sim slot is working and usable with a normal gsm simcard.

2.) ehm... yes, how i said in 1. euro system image is causing no problems after a complete wipe

3.) cdma motorola atrix 4g mdm6600 radio got reconfigured after a firmware upgrade to support gsm/umts

4.) actuall i'm hunting for a snapshot of this mdm6600 configuration, to check the difference. it cannot be so big, i looked inside, gsm/umts is complete configured, just deactivated. when i have this atrix mdm6600 config, i should be able to reconfigure xoom's mdm6600 radio

5.) my feeling tells me, the antennas are ok how they are, if not i'll search for a place inside the xoom to put additional antennas

6.) @critics: i've strong bones, my head is breaking through each wall :P

[Xoom General] GhostOfTheNet:
good news

today i got a very interesting offer. gsm/umts on vzw xoom is by 99% just a few hours away. ;)

the story behind... it seems, they picked xooms from verizon production as demos for marketing... so they also build all needed hardware into the vzw xoom's
[Xoom General] kcrudup:
So the GSM radio code for the QCT part (the part I figured would be a huge obstacle) will load and work and the RIL will talk to it?

Huh. I'm impressed!
[Xoom General] kcrudup:
The only thing that worries me about this is how far apart the frequencies between US VZ CDMA (850 and 1900 MHz), and the Euro GSM (900 and 1950 MHz) and Euro UMTS (2100(?) MHz) are. Doesn't look like much here, but that's still at least a good 500MHz seperation between the two bands, and cellular communication depends on very good out-of-band rejection.

The antennas aren't connected directly to the 6600; they go thru Tx/Rx combiners and antenna-tuning parts that are usually tuned to the bands the device is intended for. While if you're lucky, they used a multi-band antenna part, I'm almost willing to bet it's only for the more-limited case of the US CDMA bands on a Verizon- (and/or Sprint-) branded device.

But I'm more than willing to be proven wrong- and I wish you success in this, as to be perfectly honest I wish I were on the GSM bands so I can use it when I leave the States.
[Xoom General] GhostOfTheNet:
here you was wrong, the gsm xooms have different radios , so that wasn't the reason. read what i added in last post. no reflashing the radio, no hacking around, just a little qcn file written to radio's efs ;)

but after you know so much, i would like to ask you for two things. 1. share your knowledge, dont just say something, explain it also a bit. then others may be able to follow you better. 2. if its working, would you be able to pack it into a cwm compatible zip, so the people with less knowledge can mod their xoom without poking around with qpst?

[Xoom General] kcrudup:
WAIT- so the VZ Xoom's radio has all the RF parts that a GSM Xoom would need?!

I gotta go check out that iFixit teardown again!
[Xoom General] IndivisibleP:
I admittedly can't understand what you guys are talking about at all, Iam just hoping this all works out and that people like me who don't know anything will somehow be able to do this without getting completely lost. Hey, a guy can hope right?

Best of luck to you guys.
[Xoom General] ydaraishy:
The Atrix is an AT&T released device -- so it's already supporting GSM/UMTS, and AT&T only has a GSM/UMTS network. So I don't know what you're going on about here.

Are you confusing WCDMA, which is the UMTS air interface, with CDMA2000?
[Xoom General] GhostOfTheNet:
yesterday i wrote the gsm configuration to the radio, in logcag i dont get the message anymore that it falls back to cdma after the os is setting gsm network mode, but the phone app is crashing. i tried comgt. i get SIM OK, but when it tries to register to a network comgt says the radio gave an error. comgt info is reading the infos from the radio, there is no netlock, everything looks ok... except that under network types the radio says absolute nothing, but when i connect direct to the radio it do not knows AT_OSBM which comgt is using to get this info.

any constructive idea?

News for your great work ??? :D
[Xoom General] nikil511:
Greetings to all XOOM Europeanizers :-)

I'm in same situation with you. I ignored all forum advices, and flashed my Verizon MZ600 with Europe MZ601 motorola official images, and everything works fine!!

SIM is working fine, it picks up the APN settings of my GSM network.

However on boot, I get a "phone" crash msg, and when I try to select "network operator" I get another error msg.

looking at logcat, found these interesting msgs: DEBUG/MobileDataStateTracker(131): default: Received state=DISCONNECTED, old=DISCONNECTED, reason=dataDisabled

INFO/TelephonyRegistry(131): notifyDataConnection: state=0 isDataConnectivityPossible=false reason='dataDisabled' apn='null' apnType=default networkType=0

So... I'm stuck..

I was under the impression I also had to flash the baseband, as it seems we (VRZ) have different from EU ones, and baseband did not change with boot/system image flashes obviously.

I am thinking correct? do we need to flash the radio ?

If so,can someone with EU version, extract the radio image so we can flash it ?

I agree with you that motorola is not that stupid to have hardware differences on every version of xoom, if it was possible to avoid it, so we should hope :-)

I found by googling for xoom baseband, that

the Australian 3G version looks like this:

Model Number: MZ601

Android Version: 3.0.1

Firmware: GAS_ASIA_USAEVRSTUTELSAU_PO21

Baseband: N_01.83.28P

Baseband Config: UCAEVEUB1B8EU034.0R

Kernel: 2.6.36.3

Build Number: H6.1-38-9

Mine is as follows:

Model Number: MZ601

Android Version: 3.0.1

Firmware: GAS_EMEA_UCAEVRSTURTCOREEU_P028

Baseband: N_02.0F.00R

Baseband Config: UCAEVEUB1B8EU023.0R

Kernel: 2.6.36.3

Build Number: H6.1-38-1

[Xoom General] kcrudup:
Excellent news! I'd much rather have an unlocked GSM/UMTS device than one that's essentially stuck on the (primarily-US-only) CDMA network.

Please keep this thread updated- and I think that what you're seeing are in fact artifacts from the RIL for the existing CDMA baseband "bubbling" thru to an Android that's not expecting that input. I'd like to know if they go away if you can find a way to update the baseband to GSM-only.

Another interesting finding is my IMEI

it seems it is using a default/error (?)

Also, I found another European Xoom baseband details (Greek):

techblog . gr/wp-content/uploads/2011/03/Motorola-Xoom-Techblog-15.jpg

Baseband: N_01.83.00s.a2

I am gonna ask these guys for a radio image, does anyone know how to "extract" the baseband radio image ?

EDIT: actually this is the wifi version...
[Xoom General] BrokenPixel:
Australian Xoom uses 850/1900 for UMTS, maybe if you get a hold of that baseband there is a better chance that it works?
[Xoom General] GhostOfTheNet:
i think in the european version has a different radiohardware, but if not... look at qpst software downloader. sure i know with that you can extract the baseband config. i would prefer to get everything from the icanall vzw xoom(a version used for marketing which is verizon branded and can connect to all networks) but first we need one :-D
[Xoom General] nikil511:
I ve found QXDM and QPST, but I do not know what to modify, in order to change the CDMA to UMTS. Is it just "configuration" of parameteres, or "images" need to be restored ?

I have found an SBF image, of the MZ601.

It is my understanding that this image also contains radio/baseband image and the official motorola does not. correct ?

So if I flash the SBF MZ601 on my MZ600, and if the hardware is the same, there is nothing else left and xoom should be european right ?

Well I tried anyway, but with no success.

I am using Moto Drivers 5.1, and RSDLite 5.3.1, the device is detected, but I get an error when trying to flash:

Unable to retrieve initialization values from INI file.

Also tried RSDlite 4.7,4.9 same error.. tried diffrent PC, same error (always on win7x64 though)

Any ideas?
[Xoom General] GhostOfTheNet:
hooooo...

not shooting so fast, sure that the mz601 has the same hardware if not, let that if you love your xoom.

can you pm me a link to that sbf please?
[Xoom General] nikil511:
How can confirm hardware differences on MZ601/0 ?

I have been searching the web for months now! No one knows, everybody speculates!

besides, I have allready flashed the EU images (boot/recovery/system/user) with success, so whats left? just the radio...right ?
[Xoom General] nikil511:
I can not find instruction on how to backup the radio partition... (?)

Does anyone know ?

Can someone with an MZ601, backup and send us a radio image ?

Changing from Verizon to other company on Xoom

Hi Guys,

Thanks for the great work done here !

I bought a Xoom this week in USA, but lives in Brazil.

In the past, I do the sabe with Blackberry devices (that works in CDMA or GSM) that just need to be "unlocked" by code.

After read all these pages, my question is: is this possible in the Xoom ?

If not, I see that some people try (and have almost success) flashing european ROMs, but there some issues not recognized.

Can be possible make the GSM work with other cell operator than Verizon ?

Thanks for your attention.

Xoom X600 recognise the GSM SIM by Flash

Hello to all !

I posted a question about the fact from Verizon's Xoom work under CDMA but keep a SIM slot AND other models works with GSM in other countries (like in Brazil).

I spend a whole day flashing different ROMs and the model 605 make the SIM slot works and recognize the APNs on SIM, despite de the fact don't connect to internet...

I guess that's a matter to research a way to do it, but in my ignorance I don't feel safe enough to go ahead and flash back even the version of the ROM I install was 3.01 when the original I have is 3.1.

Anyway, at this point, I can warranty you that the device really can works under GSM with the SIM card on original slot...

Best wishes to all.

A guy in the following thread has created a Xoom baseband updater utility and also has the Australian baseband which I believe is GSM and so might do what is wanted here:

Perhaps someone here who knows what they are doing could work with the guy from this thread, or at least get a copy of the baseband file he uses as it may help here.

I have successfully installed his ROM on to my Verizon Xoom, however his baseband updater fails when I try to run it.

Unfortunately I've not been able to post a follow up in that thread due to me being a new user on this forum.

Motorola XOOM MZ600 is for Verizon which supports only the CDMA 2G and 3G(CDMA2000 1xEV-DO). The device don’t have voice communication capabilities. And this device will not work on any GSM network worldwide. It also has Wi-Fi support.

2. Motorola XOOM MZ601

Motorola XOOM MZ601 is Tablet with no support for GSM voice communication, SMS, and MMS. This will not work on any of the CDMA or GSM network worldwide. This can also be called the Wi-Fi model as it supports only Wi-Fi.

3. Motorola XOOM MZ604

Motorola XOOM MZ604 is also called XOOM MZ603( may be Motorola made a mistake in the naming order or it got some last minute carrier problem and that created that MZ603 to be a empty slot or guess what, expect some other carrier on that name soon). Glad that this is a GSM device and it don’t have any voice communication facilities. This model also support Wi-Fi.

Compared inside of UK 3G to Verizon 3G Xoom

Hi all,

After getting frustrated waiting to see if the Verizon Xoom can be hacked to work on UK GSM networks, I've given up and bought myself a proper UK 3G MZ601 Xoom and am going to sell my Verizon one.

This means that if there is anything anyone would like done on a proper UK 3G Xoom to extract data/settings that might help in getting the Verizon one to talk GSM then just give a shout as I am willing to do it on my UK one - as long as it doesn't involve wiping or possible bricking.

There has been a lot of talk about whether there are any differences with hardware between the MZ600 and the MZ601, and so in order to try and help answer this question the first thing I did with my UK MZ601 was take the back off and compare it to the tear down pictures of the MZ600 from - google for them - I can't post links yet!

There very obvious differences which I think are relevant to this thread are:

1) There is no fake PCI-E card,

2) There isn't even even a PCI-E slot!

3) The aerials are very different

I've attached a few pictures of the interesting areas with differences.

I recently noticed that the latest official updates for the UK Xoom include a baseband update, and so if you are just after some baseband files to try and get them on to your Verizon Xoom then they are in the latest UK updates.

Trying to install this latest UK baseband updates on my Verizon Xoom resulted in exactly the same error that I got with every other baseband update trick from other forums/discussion threads etc. that I tried - if you look at the end of the recovery last_log file you have:

..........Stating bp ......

Setting bp to flash mode...

Getting bp flash...

flash name: baseband

write 20 command: ERASE€

E:Error in /cache/Blur_Version.6.1.400.MZ601.Retail.en.EU.zip

(Status 7)

Installation aborted.

I even out of interest tried doing the baseband updates with the fake PCI-E card taken out of my Verizon Xoom (that being the main difference I could see between US and UK 3G Xooms) in the hope that that might trick it in to taking the update but it still failed.

From the error message it looks to me like there is something fundamentally different in how the Verizon is built/configured compared to the UK and that this completely stopping any GSM baseband flashing.

Hope this all is of help to someone.

Nick...
