So this is definitely a n00b question, but it just occurred to me. Does running Android on a T-Mo HD2 affect the carrier lock? I figure it's still locked to T-Mo but I wasn't sure, nor do I have a spare SIM to test. I don't really know anything about how the OS does/doesn't affect the baseband software

I never fully unlocked any of my iPhones...but what purpose would unlocking the baseband of the Nexus One serve? Is it only meant to be used by people that didn't get the Nexus unlocked?
Basically what I'm wondering is if there's a possibility of altering the wave lengths of the baseband to make use of AT&T's 3G. It would theoretically be possible to reprogram the radio to send/receive on the different wave length...but I'm absolutely not programmer-savvy enough to do it.
I was also thinking something along this line: A company should create a case that integrates an AT&T-capable radio that would work with an app they design to basically enable 3G over AT&T. It would definitely be possible...

its the BOOTLOADER you can unlock, not the baseband. The baseband doesnt need unlocking because the phone is already SIM unlocked.
Also no baseband unlock can make your antennae support new frequencies. this is a hardware limitation.

Well I knew nothing can make an antenna support new frequencies, but my question was whether the radio could support the frequencies but was only locked out of them.
I was just wondering if that were the case and if so, if it would be possible to remove that lock.

1. Agreed
2. The radio they use in the N1 supports the AT&T 3G frequencies, but it's locked out on the chip. That's why there's speculation that someone will hack a way to get 3G enabled on the device, but it will have to be modified somehow. (not physically, it's similar to how the wireless N is disabled on the HD2)
--
Someone will come along with an unlock for the freq. eventually if it's possible, I'd assume it would be, but you never know.
The only reason I made this topic was because there was another topic named "Unlocking baseband..." and I figured they used the correct terminology.
I knew unlocking the bootloader is the common thing, but I figured someone had actually figured out how to unlock the baseband to the point where they could unlock and use the AT&T 3G frequencies. That's why I came up with the questions.

Where did u get the info that the At&t radio frequency is just locked on nexus one? I'm gonna call shinanigans on that one.
A) There is no way that google would lock extra frequencies....it would just help them to get at&t customers......there is no logic there what so ever.
B) I don't believe there is any chip that supports both TMobile and At&t 3g frequencies in production. Therefore this is not even possible

Actually sometime after creating this topic I found another with a long list of spec sheets and such and they found out that the radio *does* support the frequencies but they believed that only the T-Mobile frequencies are amplified (meaning the AT&T frequencies would be fairly useless)
Hey all I'm looking for some help on a quick matter. I just sol my HD2 to someone in Canada. Hes using Rogers telecom but primarily just wants to use it as a Android phone on that network. I flashed it to a Energy Rom and the 2.12 radio. Will I need to do anything else on my end to make sure it works when he opens the box? Any creative suggestions are appreciated and yes I did do a search didn't find out anything outside of 40 pages of what I am not trying to figure out.
Is it SIM unlocked? It will not work on Rogers, or any other network for that matter if it hasn't been SIM unlocked. Other then that, he will need to setup the APN settings that Rogers uses, but all in all it should work.
Yup
I installed Cotulla HSPL2 to unlock it. I believe that should be sufficient its just a matter of him putting in the correct APN numbers now I think?
wrong, hspl does not unlock the network.
you need to buy a code online or ask t mo if you have a contract.
also, does your buyer know there will be no 3g?
?
Me under contract? Probably, but my account has me listed on a different phone the HD2 isn't on there anymore.
Now you say wrong but no details on how to correct the problem. Can you be a little more forthcoming on where I should go fix this.
Nevermind I contacted TMO and they are unrooting the phone for free and will send me the code in the few days.
*shiver* unrooting...anyways, yeah you have to SIM unlock it, and HardSPL most definately doesn't do that. And also, the 3G bands that Rogers uses are different from that of T-Mobile, so he will not get 3G data, only EDGE and GPRS.
Thats what he wanted I figured he did the research about it working on Rogers.
BTW why shiver about unrooting? It seems like it opens it up to more stuff?
Because the HD2 isn't "rooted" in the first place. Both Android and the iPhone have dumbed down the masses so that jailbreak and root are commonplace terms that people apply to EVERYTHING in the smartphone sector, and it aggravates me.

hehe with that and the bastardisation of the word "fail",society is collapsing as we watch!
Hey guys so I switched from iPhone to HTC HD2. And i got a little bit confused at one point. How do I use this phone with other carriers other than t-mobile? I have AT&T. After Doing some research I figured that I have two choices one is sim unlock which im not doing cause I gotta pay. And the second choice is radio flash? So Im confused right here. I have US t-mobile HD2, i put 2.08HSPL and have wp7 rom on it. Can I still do radio flash? If so how can I do this? And if ill do it, i will be able to use 3g data? Im sorry if im asking about some obvious things but im tottaly new to HTCs. Thank you.
Welcome to the HD2 world. I don't know specifically about the US models but in Europe, you need to sim unlock to use a locked phone on a different carrier.
Using different radio versions allows you to test and find one that offers the best balance of battery life and signal quality for your location and usage pattern.
With regards to data speed, those would be dependent on your carrier as unlocking gives you access to all the HD2s capabilities.
If I'm wrong in any of these someone will chime in soon. Have you tried using the search and looking the the very details FAQ threads? Have fun!
Sent from my HTC HD2 via XDA app
Currently no free sim unlock. Buy a code online or get from t mobile.
Changing radio has no effect on network lock.
Regarding data speeds, it depends what network you are on. Example a tmous phone on at &t wont get 3g, cos the hardware bands don't match.
Flashing a radio will not allow you to use another carrier. You gotta pay for that privilege.
Hey all posting here and a bit new, so excuse me as I had some questions.
Now, I have done research on unlocked factory phones for S5 but wanted to clarify as I will not jump into a purchase yet. I am thinking about a factory unlocked phone for the S5 on ebay. But, as I understand, this runs on GSM internationally. I am thinking of bringing one to Verizon, but as I am aware they run on Cdma technology and I wouldn't be able to use a sim card. Also, is it true the Exynos version of the S5 doesn't actually have LTE yet? If so, it may be a deciding factor.
Also, my girlfriend wants to possibly bring one to Virgin Mobile but I didn't think that you could as they are also Cdma. Again, wasn't sure how this would apply to unlocked phones from the factory that weren't locked to any carrier. I would also check the frequency, but there is no point of the international version has no ability to utilize LTE which are pretty fast in my areas. Any insight is greatly appreciated and as mentioned, I tried up read up a lot, but still want to make sure I fully understand. Thanks!

as far as I know the GS5 is not dual radio, so it is GSM only, if you want to use it on CDMA, you probably have to buy from the carrier. But be warned, as of now there is no chance of bootloader unlocking and root on many carrier devices.
Exynos version has no LTE and has very little dev support.

Hey there and thanks for taking the time to reply. Yeah seems like the phones too fresh. I will think about that then and maybe give the phone more time. Meanwhile, seeing what my S3 could do for flexibility.
Hello all,
I will need some UberGeek advice for this one...lol
I use TING as my MVNO provider. They offer CDMA and GSM networks backboning on Sprint and T-Mobile. I had to get a new phone and ordered a Sprint CDMA version G900P but received a Verizon model G900V. It works perfectly fine on the TING network.
I am just wondering if there is any reason not to get this phone and to go with a T-Mobile model instead? I normally would go Sprint/CDMA but wanted to try out GSM this time. Both have excellent coverage in my area. I also know about the ATT/Verizon bootloader being locked. I have already rooted this and it's running Lollipop just fine a sper the instructions found in threads here.
TING told me the phone is no different essentially and there should be no problems. As always their cust, svc. was excellent and informative. This phone apparently has dual radios...CDMA and GSM. I don't have to worry about warranties, KNOW tripping or Verizon's bs. As I said, I am rooted and running fine. I will either debloat this sucker or go with another ROM. Right now THE only bugaboo I see is that there are so few ROMs for the Verizon model. I am not into switching ROMs. If I ditch a debloated stock setup, it would have to be very something very clean and stable based on Lollipop. Seems like CM 12.1 could be nice but right now slightly risky and they don't have the Fingerprint feature working either.
Does anyone feel it would be smarter to return this and get a T-Mobile model? Any food for thought or advice or "Here is why you'll regret the Verizon model 6 months from now" kind of advice?
Thanks in advance!!!!!!!!
Besides the locked bootloader, the G900V is the same phone as the rest of the S5's (of course with different radios for CDMA). If you're cool with just running stock firmware forever then keep the Verizon model. The T-Mobile model would allow you to do whatever you like with it though, as the bootloader is unlocked. Virtually no possibility of losing root.

Thanks for the response. Pretty much what I figured. I have it rooted and using Safe Strap and MIGHT toy with CM 12.1 since there are many out there with the Verizon model that seem to like it. Plenty of YouTube videos too.
