The reluctance of AT&T (and HTC?) to provide/allow a boot unlocker goes hand in hand with Carrier IQ's stated purpose of gathering "performance data." AT&T needs data on its new LTE phones, so they don't want heavy users (tech savvy users) rooting the phone and wiping out their data access. Now, is it correct that the Samsung Skyrocket can be rooted? If so, that supports a comment elsewhere that Samsung stood up to AT&T but HTC gave in.
Of course, most phone users are not going to root their phones, so AT&T -- and other carriers with Android phones -- can still get a lot of data.
The problem, as I understand it, is that Carrier IQ appears to be gathering much more data besides "performance" data.
This is what I originally thought as well. Even aside from CarrierIQ, if AT&T really is the one at fault for the locked loader on the Vivid, it's probably because it's a totally new device for them. They need to "collect data" and gauge users' experiences based on the actual phone with the software provided, perhaps so as to be aware of any problems that may arise and know how to improve the next devices. The Vivid IS also the first all-new phone to AT&T that supports LTE.
The Skyrocket may have come unlocked because even though it's LTE, it isn't actually that new of a device... it's just the Galaxy S II with LTE capability. Before that was the Infuse, before that the Captivate, and whatever. There could be a million reasons as to why one is unlocked and the other is not. That's just my reasoning behind it all.
The skyrocket is totally different then the sgs2 it is a brand new phone. Diff gpu/cpu different display size

With the recent influx of Droid devices generated by them being handed out to many individuals through Google's developer channels, I imagine I'm not the only one wondering whether or not it would be possible to get service for this device by anyone other than Verizon. I'm hoping that someone can explain to me what it might take to make this possible.
As I understand it, VZW uses both 1900 and 850 while Sprint uses only 1900 with roaming possible on 850. That means the device should be compatible between the two networks from a frequency standpoint. What I'm not sure about is whether any of the software instructions coded into the VZW/Sprint devices are important to the correct operation of the phone on the network, or if they are identical and it only matters which network accepts the device's ESN.
In short:
- Would any software modifications to the device be necessary for appropriate functionality on the Sprint network?
- If so, could those modifications be derived from existing Sprint Android platforms like the Hero/Moment?
I have been given a free Droid, but I have no plan on ever switching to Verizon. It will remain a development only device if I can't modify it to work with my existing Sprint account.
Thanks in advance for any information.

Illegal, huh? Good 'ol US; the only country that feels the need to so tightly bind our devices to specific carriers. I vastly prefer the unlocked GSM phone model that Europe operates under. Le sigh.
Thanks for the info. I'm unlikely to sell, as I can find uses even for a device that doesn't have service. I just thought I could kill the proverbial two birds with one stone if I could make it work. C'est la vie.
You're forgetting the fact that there are at least TWO major nationwide GSM carriers in the US.
Japan has better game-shows than the US does, but I'm not going to say, "good ol' US" when complaining about it. But, I wouldn't even complain about it.

I'm not forgetting at all. The difference is that phones here, even for those two carriers, are sold locked rather than unlocked. Many consumers don't even know they have a choice, nor are they aware that their phones can be unlocked. The fact that the phones can be unlocked, and maybe could be used somewhere else in the world (depending on whether or not they support non-US bands), hardly excuses the fact that a tiny number of consumers would ever even realize that, or go through the hoops and hurdles necessary to unlock their phones.
This is a far cry from a market with many options for carriers where phones are sold unlocked and can be easily moved between any available carrier. The Wikipedia listing of mobile network operators in Europe (which I can't post) is quite illuminating when you realize that countries a tiny fraction of our size have a lot more than 2 choices that the phones they purchase, their property, can operate on. I would say cheering that at least we have two choices seems a little silly when the competition level here for carriers is so much weaker than elsewhere in the world.
Let's just say I'm more than a bit frustrated that what I've been gifted is, in the absence of one particular company's service, a brick. The phone belongs to me, yet whether or not I can use it as more than an alarm clock is dictated by only one company. It seems a little silly, and more than a tad bit frustrating. I would have much preferred an unlocked GSM phone; not only would I have two networks, albeit only one with 3G, to choose from, but my international options would have been wonderful.
Ok, so long story short.. there is no way to get the Droid A855 on gsm even if its unlocked? I know I just might be in the wrong forum but I have been searching all freaking day and honestly every site is starting to look the same to me 10:1 I'll prolly just sell the phone back off

No, because the A855 does not have a GSM radio in it. Without the capable hardware, what you want to do is impossible.
Okay so yesterday my dream phone came out on sprint network the HTC X8T I really like this phone a lot. to my understanding the HTC X8T Is a lot like the HTC ONE with boom sound and front faceing spekers. but yet running windows phone 8. so I am very interested In this phone.
but yet I have a lot of questions.
1. is there an unlocked version of the phone I can buy?
2. is sprint the only ones selling this device?
3. could this device be used on boost mobile instead of sprint.
4. what are the chances of a boost version?
5.why is there not new fourm for this new device?
That should be a good start thanks.
1. Unlocked version: Maybe. Sprint uses CDMA2000, rather than GSM, although they might use SIM cards for LTE support like Verizon does (I haven't checked) typically, CDMA2000 phones won't work on other networks unless those other networks also use CDMA, and sometimes not then (because they're locked). I don't know yet whether the 8XT will be available unlocked in general, or available for GSM.
2. Sprint only seller: So far as I know, yes. If there's a GSM variant, you'll be able to buy it internationally. If not, then they will probably be the only one this side of China or something. I'd expect a GSM variant, but I don't know.
3. Use on Boost: See the answer to #1.
4. Boost version: I doubt anybody here knows. You should ask Boost Mobile about that.
5. New forum: Many WP8 devices don't have their own forums. Until such time as custom ROMs or similar are possible, one WP8 device is much like another, so there isn't usually enough traffic to justify per-phone forums.
By the way, the 8XT looks somewhat liike the One, and has the same speakers, but its specs are considerably worse. Its screen is lower resolution, and I believe it's processor is much less powerful.
HTC has not announced a version or variant of this phone for anyone except Sprint, so for now, we can only assume its a Sprint only device and does not come unlocked. Considering that Sprint is CDMA, it wouldn't be wise to purchase a Sprint branded phone to use on other networks as it will most likely not work. Boost has been known to activate Sprint phones on their service, but its very hit or miss as you need to speak directly with a customer service rep, and that itself is difficult. XD

You only need to look at the radio specs for the phone. I knew it was for Sprint a full week before the tech i was on the phone with did and she was Tier 2 support with 'upcoming training for some new WP8 device' but didnt know what the hardware was.
It runs on the 1xRTT network, so wont even work on VZW. Also given that Sprint is (or at least used to be) an HTC Premier Partner its no surprise they made a phone that only Sprint would carry. Its smack in the middle of the 8X and 8S but what sucks is we are stuck with Touch Pro2/Arrive resolution on a screen thats nearly 33% bigger (4.3" vs 3.7"). Will i get one? Im still on the fence as my TP2 still does the job for me, even without native apps for Twitter or games.
I am thinking of getting the LG G4 on T-mobile because of the price and features of the phone, but I have a few questions before I drop all my money on a phone I plan on keeping for at least the next two to three years. Before I start, just understand that right now I have a Lumina 635 with windows 10 preview so I'll be comparing the phone's useability to that.
1. Does the Phone have an IR blaster that can be used with TV remote Apps, such as Anymote, or Smart IR remote? If I ever do any kind of home automation, I need something With NFC and IR capabilities.
2. If I get an AT&T version of the phone, how hard is it to transfer to T-Mobile. I have unlocked a few phones before, and I understand basic computer/mobile device tweaking.
3. Can I/should I get the international/unlocked version?
4. How is the G4 compared to the G4 stylus?
5. Can I get this phone, and unlock it without that affecting my service from T-Mobile. I don't want any custom roms, I just want to make sure that I can get the newest versions of Android If, or when, LG decides to stop pushing them out themselves. I am moving from Samsung devices aside from my Windows phone stint, and the Samsung/Tmobile combo has always been slow to push updates, as in over a year behind the curve slow.
I want something that is pretty new in its life cycle but I'm not paying over four hundred bucks for a cell phone. It came down to this or the S5, and I'm thinking this is a little newer, cheaper, and has more time left on its support life cycle, which is why I chose it. Thanks.

1) Yes
2) ATT phones work well and with lte on t-mobile network. I am not up on ATT and unlocking phones currently, but in the past, it was cheap and easy. (I only present that caveat as T-Mobile has since made unlocking their phones a cluster-F of frustration and/or failure using a special app of theirs...no ability to just buy a code and input it , as was always the case in the past.)
3) International model lack some bands tmo uses and is best on, so I suggest a domestic USA phone.
4) no idea. sorry
5) Sim unlocked has nothing to do with getting android updates. If you unlock your phone and use it on a different carrier, you aren't going to get updates and would instead need to flash them yourself once and if available. Unlocked or not and ATT built phone can only use ATT roms, not other carriers roms, even for the same phone model.
Also, the T-Mobile (H811) is the only G4 that has an unlocked bootloader. Since you say you have no plans to root, this should mean 1absolutely nothing to you, as it is only something a rooting/roming person would care about. Just want you to have all the facts.
Hey T mobile users, I currently have a Sprint note4 unlocked on Cricket network. As you may know I only get hspa speeds this way, Not a super big deal to me. As I've had the phone this way for a year now. Only reason I even ended up this route is because i got the phone (at the time) real cheap from a relative.
But now that I've seen the prices drop quite a bit cause of its age, my question to you is first will the t mobile phone get lte speeds with Cricket(at&t)? It looks like to me it has them bands.
Second, Do you think it's worth the hassle? I figured I could comp the price by selling mine afterwards.
Your advice and opinion is appreciated. Thank you!
It WILL work, but it isn't worth the hassle. With T-Mobile you would only benefit from VoLTE and WiFi calling. You can root your existing phone and flash a ROM with the T-Mobile system files and keep your.
AT&T and T-Mobile note4 is the same hardware-wise except the bootloader, modem and corresponding kernel required to make WiFi calling work for the N910T. The N910A is punished with the locked bootloader, so I can see your concern.
If I understand you correctly: You wish to keep your current carrier, but to switch phones just to get LTE speeds?
I have a 910T running on Cricket's network. I think I paid $150 for it used which was a huge upgrade from the HTC Desire 510 I was using. It had a burnt in screen but I learned to deal with it for $150. Also has some other quirks that usually only show when a phone's been water damaged. I learned to deal and get around them though. Because of this, I don't recommend buying a phone used. And since you're content with your Sprint model, I might just stay with that.
The reason I went T-Mobile was because of the unlocked bootloader. And there's no doubt in my mind that I'll have this phone for another 2 years. It's a great phone and after Samsung took a bunch of features away with the Note 5 and then created an exploding Note 7, I'm quite happy with this device for a while to come. Now the rumor is that Samsung might be taking away the 3.5 headphone port. If that's true, **** them. I just used my headphones for over 6 hours on a Greyhound bus and Bluetooth requires charging which I don't wanna deal with.
I can't tell you what to do but if it were me, I'd stick with the Sprint model. But I do love custom ROMs so...
****If you buy a note 4****
Only buy a refurbished or recertified one with a full warranty...
There's reported issues with these phones real or imagined... don't take the risk!!!
Good Luck!
Long time lurker, first time poster here. First of all, a massive THANK YOU to everyone here. You guys and gals are Awesome! <3
So, I bought a Samsung S10 (SM-G973F/DS) on Ebay recently and flashed it to Lineage OS 19.1. All was fine until I tried to activate it. We did everything...manually changing the ASP settings, and a bunch of other stuff to try and get this thing to connect to the mobile network. Even placed the SIM card in another phone just to confirm the SIM card was fine, which it was.
Long story short, I think the device was perhaps locked even though the seller claimed it was unlocked. Whatever, I'm over it. I flashed stock back on it and re-locked the boot loader, sent it back. Not worth the aggravation. However, I am questioning if there wasn't something else I could have done?
I was trying to activate the S10 on Mint Mobile USA (a T-Mobile reseller, so GSM) it should have been fine. The default language on the device was German. I don't think that should matter, but maybe it does? Do European phones have problems activating in North America?
My question is: If I decide to get another S10 (SM-G973F/DS) from the secondary market (if its even worth it at this point, since the SM-G973F/DS is really hard to find), is there anything I can find out from the seller first so I don't end up having to send it back?
Or, should I just give up my dream of having an S10 installed with Lineage OS and it's glorious headphone jack and expandable storage forever? If so, are there any worthy alternatives to the S10 worth considering, given my affinity for headphone jacks and expandable storage?
Hello PhonePerfection, all a novel why you speak S10 G973F / DS in the United States.
Already your model S10 G973F/DS exynos 5G or the first 4G model so if these this Europe chip model, if now installed Samsung phone info look at who is scoring at worst take screenshots.
I don't understand your question United States, locked unlocked the seller.
You buy in the back market refurbished and unlocked telephone all operator therefore for sim card, the concern these the chip to install network either US or ASIA controls your model if these good SM-G973F/DS and not SM-G973U or G973U1.
Don't forget to say hello
I think what @meric57 is trying to say is that your phone doesn't have the right chips to communicate on the frequencies in the USA. It's made for other markets and other frequencies... so it won't work here.
If you use FrequencyCheck you can see what carriers support what frequencies on your specific model: https://www.frequencycheck.com/comp...m-td-lte-512gb-samsung-beyond-1/united-states
Scroll down to the "United States" area and you'll see it doesn't support the frequencies used in the USA (except for GSM 2.5, which is old and dead here in the USA). The US is primarily on LTE... and you can see that phone model doesn't support ANY of the available frequencies.
Bottom line "GSM" doesn't tell you enough. You have an incomatible phone model for the USA market. No SIM card will fix that.
Note, in SOME cases, you can activate other frequencies by loading different ROMs into the phone. My old LG V30 did this, for example. I have heard that you can run some Exynos phones here in the USA, but I don't know the details to help. FrequencyCheck may help you figure that out. Be sure the look for the complete model number, not just "Galaxy S10" or something... the naming is worthless for figuring this out.

Hey, this is great info. Good to know. It looks like that S10 could only communicate on 1 of 8 bands used by Mint/T-Mobile. That 1 usable band appears to have been deprecated by T-Mobile as it is. I think that explains it perfectly. Thank You!
You're welcome.
Yeah, frequencies/bands are very important to watch, particularly if you're buying out of market devices. You have to know model numbers and carriers to be sure of anything, and unfortunately this info is relatively hidden.

The CSC on that device was DBT (Germany). I had to find that out in order to put the correct stock OS back on there.
Makes me wonder if the ebay seller even knows this. They appear to specialize in mobile phones with tens of thousands of transactions, so I would hope they've encountered this situation before. They were more than happy to accept a return on the device. Sent me a prepaid shipping label immediately.
Back to the CSC... Let's say I look for another S10 (SM-G973F/DS) but I ask what the CSC is for that device. Are there any regions outside the lower 48 states with reasonably good chances of it working? I suppose I would need to study the mobile frequency website for the answer to that.
I did some quick searching, and supposedly there are websites that say the 973F/DS will work on MM (mint mobile)... but they don't detail how. For example: https://de-googled.com/blogs/news/a-word-on-network-compatibility-of-our-degoogled-phones
and https://www.ebay.com/p/15030406771 (in the description).
So, maybe it is possible? I don't know, so maybe someone else can chime in.
Personally, I stuck with U-version phones and gave up rooting/romming. It's just getting too hard to find phones that offer this, so I figured I'd just adapt back to a stock ROM, since choices are limited. I had done a bunch of that in the past, but I found that stock roms (today) are pretty good... and allow enough customization that made root/rom unnecessary... for me. My current is an SM-G975U1 (unlocked, USA, Snapdragon S10+) on Total Wireless (VZ MVNO)... it works great and I don't miss root/rom at all.
Rumor is that the Galaxy S23 will only be offered as Snapdragon, so maybe that will open up more options... but I doubt it. Samsung loves it's Knox system, and will likely lock down the phone even more with every generation.

Thanks for the link. I think I may try for an S10 again if the seller can tell me what the CSC is. That page on De-googled.com affirms that American devices are more restrictive than their European counterparts.
It just doesn't make any sense to me personally to use a device with an open source OS that has loads of telemetry, spyware, bloat, etc. Which is a contradiction that I am not comfortable with. It's like installing a Linux distro that comes bundled with Facebook.
To me, being proactive about privacy is the equivalent to standing up for yourself in the real world. Sure, you can use a stock ROM and there is nothing wrong with that. It's having the freedom to choose which is most important. So long as that choice is available, I will happily go that route.
I like the added bonus of an Android device that seems faster with a longer lasting battery as well. I mean, I paid for this device. I should have the right to decide what apps are running on it.
No argument there... I agree with why we should be allowed to root/rom. Unfortunately, the carriers pull the strings in the USA (business over people) so we are losing options. Frankly, it pisses me off that they can still prevent phones from connecting to their network just because the IMEI doesn't match (even if the software is correct). In the end, if the device CAN work on the network, the carrier should have no say in allowing/disallowing it on the network. They like to claim that a "bad" device could "hurt" the network, but if that happens, they can lock out that phone and figure it out. I doubt that's even ever happened, but whatever. (They prevented me from using my already-working V30 US998 phone on the network, even though it ran as VS996 with no issues for years... they only later saw the IMEI wasn't "theirs" (original SIM card failed) so they prevented me from re-registering it. So stupid.)
Good luck, and let us know if you figure it out... I'm always curious to learn!
yes, most japan and europe phones do not have the correct radios channels in them for 4g and 5g. i ran into this same problem with my xperia phones that i bought overseas. this is a common problem that can happen.
The S10 and all it's variants is a world compatible GSM phone. So yes, the F variant should work with most GSM carriers and resellers in N. America.
There are various websites that will tell you what frequencies and carriers any particular model will work with if you do a search. Like this one.
WillMyPhoneWork.net - Check if your phone works on a network
Check 2G, 3G, and 4G LTE Network Frequency Compatibility for a Smartphone, Tablet, and Mobile Device in any Country and Mobile Network Carrier

According to that site the SM-G973F/DS supports all 2G, 3G, and 4G frequencies used by Mint.
