Title.
I was one of the battery recall shield tablet owners. I flashed a custom rom on my old tablet to prevent it from being disabled, and now I want to see if I can do more with it. Is it possible to unlock the LTE bands for use with my Taiwanese 4G Sim Card?
you might have to check to see who makes the lte chipset used in the nvidia shield... if its qualcomm then you can use their qualcomm tools to unlock the bands

Hello
It sucks being an european and to have a 4g/cdma phone because in my country (Romania) you dont have a cdma network
So as we all know the Thunderbolt has the same chipset as the Rezound so in theory it should be able to transform into a Global Phone.
My question is why didn't anyone do that and how i can make one myself if a dev dosent bother.
I feel it in my guts that this will work but i need some guidelines, or someone with actual knowledge to help me.

Thunderbolt doesn't have the hardware. Not possible.
and what hardware are you talking about?
Thunderbolt has a CDMA radio and an LTE radio. Global phones need a separate GSM radio to work in Europe. If it has an unlocked SIM, the Thunderbolt should work on any 700mhz band LTE network, but is incompatible with GSM on all levels.

MDM 9600
Actually, the Thunderbolt has an MDM 9600 baseband chipset that supports Hspa and Hspa+ which is a technology that At&t and T-mobile uses for their data connections. So, I believe that if the LTE radio is backwards compatible with those frequencies of At&t or T-mobile that it might work. The thunderbolt has two antennas: one for strictly CDMA and the other for lte and backwards compatibility to gsm/hspa(+) from what I understand. From what I have read Verizon has just opted to not install the drivers to support the GSM/HSPA(+) side of things. That, and the MSM 8650 processor or other hardware in the Thunderbolt may not support it. Just because the modem supports GSM/HSPA(+) doesn't mean the phone will, but I do think that if someone really wanted to they could modify the thunderbolt to work on GSM. The may need more hardware, but I do not know.
I would post the link about the chipset I have, but sadly as a noob it will not let me.
P.S. Verizon allows you to log-in to your account and view the unlock code for the thunderbolts SIM yourself. You do not have to call them. I have not used another Carriers SIM in my Thunderbolt, but HAVE read about people who have in other threads. Verizon from what I understand and have read on other forums does not allow you to use USA SIM cards other than VERIZON'S own SIM. From what I have read, it only unlocks the phone to use foreign country SIMs only. From what I had read, once you use VERIZON'S SIM unlock procedures a NEW menu pops up in your network settings giving you the option to select to use GSM only. The same thread was speaking about the iphone 4s and the Thunderbolt and said that Verizon allows for both to be unlocked and used as World Phones. I will not know for sure until I see proof, but I do know that Verizon allows you to unlock the Thunderbolt's SIM to use on Foreign Networks.
The MDM9600 baseband definitely supports quad-band GSM. However, the RF transceiver in the Thunderbolt may or may not, and the power amplifiers definitely do not. You need all three in order for a mode & band to actually work on a device.
Not possible from a hardware point of view.
Same question over and over, no-one searches the 10+ times it's been answered already.
IF you want to use LTE on a Razr HD on AT&T, Rogers, Fido, or internationally, you have to get the XT925. The Verizon-specific XT926 is bootlocked, carrier-locked, and doesn't support LTE on any other carrier. That's why it's locked to Verizon. In order to support all the CDMA data bands, they apparently intentionally gimped the LTE support.
Bottom line, if you have Verizon, buy a xt926. Everyone else, get a xt925. And no, there is no Razr Maxx HD anywhere else than Verizon currently.
ALSO! The XT925 is the only model with an unlockable bootloader currently. If you have a XT926, you can run a hacky-workaround to run custom roms... However all the development I've seen thus far is either XT925 or XT926 focused, and there isn't unification between the two... yet.
Ha. It's not that it's SIM locked (it *is* if you try to use it on AT&T) -- it's that Rogers/Bell/TELUS have different LTE frequencies. The Verzion version only supports LTE 700 MHz Class 13, while the Canadian providers use LTE on 1700/2100/2600.
So, if the Verzion version of the phone supported those frequencies it would work the same. But it's *not* a case of being locked at the SIM level, except AT&T/T-Mobile.

I never said Sim locked. I said carrier locked. Does it work on all carriers? No. Therefore it is locked, don't you agree?
Let's say I buy an international One X. I unlock it myself. Would it accept a sim card that is for the XL and still give someone 3G?
[Not that I'm actually doing this, just curious ]

It should. Assuming the sim card slot fits the same size sim card, if not you could get an adapter if it needs to be bigger. It should work on any gsm network after unlocked
Assume you are talking about the quad core Tegra3 One X, which most people call the "international" version. Although the dual core LTE Snapdragon version has been released in so many countries in various parts of the world at this point, calling the other (quad core) version "international" is somewhat moot and confusing.
Whether you get 3G depends on what carrier you are talking about. The quad core One X has the proper 3G bands to work on AT&T (850 and 1900 MHz). But it lacks the AWS (1700/2100MHz) band that for the most part is needed to get 3G on T-Mobile (although they have been adding 1900 MHz in some cities). I know you have the AT&T logo as your carrier. But you seem to be asking a generalized/hypothetical question, so I'm giving you the most correct answer in respect to that type of question.
In general, if a smartphone has the proper 3G band compatibility with your carrier, as long as the phone is SIM-unlocked, it will work on 3G. You will likely also need to manually enter your carrier's APN info into the phone settings.
My nvidia shield cant get 4g network where my phone does, at first I tought it might be a network problem or SIM problem so i swapped the phone and tablet simcards without any improvement. My oppo find7 can access 4g with both simcards and the nvidia shield with neither of them.
Its the EU model so it should work here, according to the specs it supports all the LTE bands available in spain
¿Does anyone know what could be the problem? ¿ Anyone got 4g properly working?
I am on latest 5.0.1 update.
I just got a D6603. I'm on T-Mobile and I wanted the phone to be rootable so I got the unlocked version instead of the branded D6616. However, the D6603 doesn't have LTE band 12 support, which means my signal at my desk at work is weak and frequently goes out altogether.
I found this guide on unlocking all LTE bands for a phone with a qualcomm processor. I was wondering if this is actually possible for the D6603 (i.e. band 12 is just blocked by the firmware) or if the D6603 lacks a certain radio necessary for communicating with band 12 towers. Has anyone tried this, or any other similar hack, for enabling a certain band or frequency on a phone that doesn't normally support it?

Check this to see which baseband exactly is you want to unlock and if your device supports that baseband. If the radio is missing, it would be impossible to unlock it. However if it is just the software, maybe following the guide help.
See attachment for your reference.
Or just wait for lollipop update. Just came across it
