Subsidy Unlock and You. Well, Them.

I've been doing a lot of research on this but I'm still coming up short on a few answers.
I'm considering purchasing a Droid 3 but here's my particulars:
My personal service is V-dub. Business service is AT&T. Assuming I unlock the Droid3 can I use the V-dub service while I'm stateside and leave the AT&T SIM on-board the device? If so, is it possible to switch between AT&T/VZW service via software?
When I'm traveling international would I be able to switch to the AT&T SIM service without racking up mad billz on the VZW side of the house?
ANyone with some experience on this would be appreciated. If I can't do all this with one device then I'm leaning to buy a Nexus S.

I wanna say you can because your phone allows you to switch between GSM/Global/CDMA.

I believe this can work with the XT860 model from canada, the US XT862 however, cannot move between US carriers, but can be used anywhere outside the US
At least, that's what I've gathered from lurking here for a while.

From what I have read the US GSM carriers are blocked out from being used in the phone.

According to a guy at this link Team Black Hat sells a *full* unlock code for the 3's which will allow it. This is unconfirmed but I'm Googling...

if i recall correctly, TBH offered a version of the D2G baseband firmware which they'd modified to run on any network, this cost you $100 and you had to mail it to them
i believe Cellzealot has stated that this method wont work on the D3

TBH released the band unlock to the public couple of months ago.It is now free. It only works on the oldest D2G radio firmware. Newer firmwares cannot be unlocked since Motorola moved the protection inside baseband which due to locked boot loader cannot be modified. This method will not work on D3 for the same reason.

Droid 4 for Hong Konger?

Hi, I am currently using Milestone 2 (non-us Droid 2) and I have been using this phone for around a year and a half. I have rom the phone, overclocked it, themed it. I have juiced every drop of my phone out.
Now the "C" button on my keyboard is a bit messed up, i need press down hard so that the phone can sense me.
Now I am 50/50 about the Droid 4 ( Milestone 4), I am a huge MotoFan, and I am a keyboard fan, leaving me no choice but choosing the Dorid series. But the current Droid 4 is only 1.2 dual core, 1785 mah battery, and rubbish screen, worst of all, I am from Hong Kong, tho the Droid 4 is a world phone, I am not sure if the phone will work in Hong Kong, a GSM city.
So will the Droid 4 work in Hong Kong, and should I get the Droid 4? (Or wait for Droid 5)

The Droid 4 currently cannot be used on GSM/UMTS networks. It does have a Qualcomm MDM6600 chip which technically can support both CDMA/EVDO and GSM/UMTS networks, but you'd have to flash a different baseband which I don't think is possible at this point.

Not yet. The currently shipped radio firmware has no GSM support. We're all still waiting for an update to provide GSM...
(Also, my D4 is still SIM-locked.)

Sorry to hear that Unfortunately there is no way to use the Droid 4 on GSM/UMTS networks at the moment.

I found some successful cases in forum from China
But need to order the unlock code
Anyways i would order my xt894 and have a try
If i got luck i will tell the buddies on this forum~

Got a link for the order? My Droid 4 is coming in this week. It's at customs now. I live in NL, so trying once wouldn't hurt me.

VZW should unlock it for you if you call and ask. I think you have to have already met some minimum account duration and payment requirements.
I too am waiting for the GSM firmware. With VZW's CDMA roaming, I can go to 40+ countries, but not to Europe.

I finally got my droid4 in hand and confirm it got gsm function is working in Hong Kong!
However, I got it with GSM ALREADY UNLOCKED so I cannot tell you how to unroot it
But probably involve flashing chinese rom

I would like to post the info, any hot-key could take a screenshot in motoblur?
Previous key in milestone3 doesn't work here
And any way to map the 'alt key' back on the physical keyboard?
The info I gathered so far hinted the unlocking involve flashing another rom, *#*#2468#*#* and unlock the device with unlock code, but I got my phone unlocked out of box so I couldn't test it

i found this http://www.buyonsalecheap.com/motor...ocked-verizon-new-without-contract_p1190.html but it dose not look like a trustworthy site and its the only GMS Driod 4 i could find.

Do not buy from that site. Its a scammers site. Not trustworthy at all.
@Disablewong I'm very curious. I too am waiting and trying to use the GSM radio on the Droid 4. Where did you get it? What rom do you use?
Do you know where I can buy an unlock code? I'm not a Verizon customer so they cannot help me. And I tried some 3rd party unlock sites, but none of them was able to generate an unlock code for me.
Thanks in advance.

There is a way to know if this device is a real Motorola Droid 4? I found some weird links about it[1]

VMU,
Which ones did you try? I want to try this one because of their success with Razr and Atrix. Not so sure about a ferund though when they do not succeed.
http://sim-unlock.net/simlock/New_Motorola/Droid 4/

I tried mobile2mobile, networkunlockcodes, and unlockitnow.
I also found the site you mentioned. But before I contacted them before I place an order. If they can guarantee that they can unlock the Droid 4 I'll submit my imei.
Waiting for a reply.

Guys, will you expect the phone will work as GSM after unlocking? Or you will use it as CDMA?

[Q] Please I need urgent help Droid phone GSM

hello every body
first thanks for your great efforts , I am seeking your help again plzzzzz.....
I had droid 3 and stolen from 2 days ago I live in Egypt with GSM network , My Droid 3 unlocked was working perfect here) , now i will get a new mobile , I guess it will be Droid 4 as extend for my beloved stolen phone
When I was looking for it on eBay and Amazon I became so confused , as I found
1-Version Droid 4 locked
2-Unlocked Droid 4
3-Unlocked Droid 4 international use
Now my question is which one will work with my local GSM ? please note that a big price diffident between unlocked and locked one , the locked one is more more cheaper , if I buy the locked can I locked it and works perfect with GSM or have I buy unlocked one ?
Thanks in advance

AFAIK they are all the same. If it has ICS it is unlocked for international use. If it still has Gingerbread, I think you can still upgrade to ICS using WiFi.

The only lock on the Droid 4 is that you cannot use it on American GSM carriers, i.e. T-Mobile USA and AT&T. This lock is irrelevant to you as you are in Egypt, unless you intend to travel to the USA and use this phone.
The unlocked one is being sold by Devices Now. It is possible that they have found somewhat to unlock it for US GSM, though if they have they aren't sharing it with these forums. They are a pretty good seller as they were one of the first to offer this phone pre-flashed to ICS for people wanting to use it on GSM.
That said, if you are happy enough with flashing the phone to ICS yourself, and don't intend to use it in the USA, go ahead and get the cheaper one.

thanks a lot Lum_Uk , but is the flashing is just updating the phone to ICS ? I mean when i bought the cheaper one just i need to update it via wire wireless or i have to do something else ?

To flash ICS all u need is the phone and a wire to connect it to your computer (and possibly a sd card).

Yes just updating it to ICS, though many people have found that the OTA update doesn't always work, so have to flash it the hard way

Just a little update for everybody here. Just because a Droid 4 has Ice Cream Sandwich or Jellybean doesn't mean it's already unlocked for GSM or international use. Having an Ice Cream Sandwich or Jellybean ROM means that the phone is ABLE to be unlocked from the carrier. The phone DOES NOT come unlocked with each ROM. You have to call Verizon to get an unlock code or pay for an unlock code through one of the measly online websites. I have much experience with this as I was in the Army for a while and took my US Android phone to Iraq and Kuwait with me. You have to put an unlock code into the device for it to be unlocked. Therefore...I would purchase a Droid 4 that has been unlocked previously. You can tell when you put a different SIM card into the phone,it will ask you for the unlock code or tell you the device is unlocked. Just wanted to clarify that for everybody.

Sorry but this is complete rubbish. It may be true for other phones, but the Verizon Droid 4, once flashed to ICS or JB, will work internationally without any codes, custom ROMs or hacking.
My Droid 4 has never even seen the Verizon network, and I don't have an account with Verizon and no way to contact them to get a code. It just works.
Plenty of others in the same situation on this forum, loads of us are using it on GSM without having to get Verizon's permission.

^^ Truth! There is no SIM lock on any VZW Motorola LTE capable device.
The last Verizon Motorola global device to have a SIM lock was the Droid3, which was a CDMA/EVDO/GSM/UMTS global device.

Hahaha schooled! Not trying to be mean but its generally smart to know what your talking about before u spew bullish out of your mouth and look like an idiot. As lum stated droid 4 isn't locked to Verizon or any carrier. Through build prop tweaks it does work very nicely at that.

Should probably add, since they are in Ohio, that GSM is locked out for US carriers. This isn't locked out with an unlock code but at the firmware level. So far nobody has broken that and unlock codes don't exist. There's a big sticky at the top of the forum with the current progress in dealing with this problem.

[Q] XT1050 Android Update

Hey Guys. Love the forums. Searched but still not really sure about this. Couldn't really find much information for the XT1050.
About two weeks ago I purchased a Moto X from my carrier. They are a very small carrier. The firmware on my phone is android 4.2.2. It's the ghost_row.lra version. I would like to update to 4.4.2 (or to the most current version of android possible) but I can't find the update for my phone. I called Motorola and they told me that all updates have been released for ALL phones and that it's up to my carrier to release. With my carrier being so small, I have never seen them release a software update for any phone (except the iphone which apple updates). After searching I couldn't find any 4.4.2 firmware for the xt1050. Almost every setting in my phone references Verizon, so I was wondering if I could just possibly flash my phone with a Verizon rom? My biggest hold up is that I kind of thought the Verizon Moto X was the XT1060, does that make a difference? With my phone being pretty generic does this mean that my bootloader is unlocked and if so would flashing it lock me to a Verizon rom?
Any help would be greatly appreciated. Just not really sure what the best/safest thing to do is because I would really like to keep my phone up to date.

I personally am thinking its not a good idea. From what I am reading your carrier, Thumb Cellular, did partner with Verizon Wireless for the rural LTE project. That might be why you are seeing verizon wireless in certain parts of your phone.
It might work...might not. I dont think it will though. Have you reached out to Thumb to see when they plan to update to 4.4?

Would there be any custom rom that I might be able to flash? I haven't found any specifically for the xt1050. I haven't contacted my carrier yet. VERY SMALL company. I may have to ask them but 90% of the time I have to go to my carrier for troubleshooting they never have any idea what I'm talking about or how to fix anything.

The only way to flash a custom rom is if you can unlock your bootloader. Otherwise you are stuck with ROMs which have been digitally signed by Motorola.

You try this???

I can confirm, working fine in Hungary too. Would recommend to install Mentor's ROM/patch though, in order to be more optimized to GSM/WCDMA networks.

You should have no problems - I'm in the UK and I've bought 4 or 5 in my time. Agree that you should install Mentor's patch if you are using CM11, but stock ICS and JB worked fine for me as stock.
Cheers,
Steve.

Agree, works out of the box with stock, but it's better after the patch. Better signals, MMS working properly, etc.

Thanks you all. Last question: It isn't important whether phone is lock or not in verizon? Can I unlock by root/flashing in home by myself? I had only 1 phone with android and I'm not sure that.

AFAIK there's no difference at all between the phones that say they are locked or not to Verizon.
Basically, if you are trying to use the phone in the US, then they are locked. Period. You can't use a Droid 4 in the USA on any network other than Verizon - it seems to be hardwired into the firmware (I'm not sure whether this applies to people with non-US SIMs when roaming in the US though).
As far as the rest of the world is concerned, then the phones are "unlocked" in that they will accept any non-US GSM SIM and work in that country. I think this was the case from the ICS Android release onwards, and only the original GingerBread ROM was locked for international use. Non-stock releases, such as CM11, do an even better job of handling GSM connectivity, especially with Mentor's GSM patch.
Cheers,
Steve.

This is exactly what I wanted to know. Thx.

Same here. I have a Verizon Droid 4 working perfectly in Spain after gsm patch.
