M on AT&T/StraightTalk, GSM Frequencies, Verizon blocks? - Droid RAZR M Q&A, Help & Troubleshooting

I've heard that Verizon phones, though "global" are locked from the US GSM frequencies.
I'm considering getting a Razr M and using it on StraightTalk AT&T or T-Mobile prepaid.
It appears the frequencies should be fine. 850/1900 UMTS/HSPA + GSM.
Anyone have any thoughts on that?
I'll need to trim the SIM down to MicroSIM size, and get the phone unlocked, but besides that...?

Well it's an atom processor not A15, lower graphics performance by far, less apps in the market and can't get it in White.

See my post on your question in the Q&A board, and posts 18 and 19 in this thread.

Righto-,thanks. I read somewhere else (maybe it was you?) that the NV settings in the radio block MNC 230 (tmo) and 150 (at&t). There was a guy who had looked all through them and couldn't find where it was happening.
Is this MNC blocking something that would be remedied by buying the Austrailian version? I want an A15 CPU + GPU not the Atom one, simply because I like sticking it to Intel, and because I like the white phone not the black one.
Does the developer edition work with AT&T/T-mobile? Maybe I'll just buy that. This phone certainly is slick. I hope whatever fix we get will let us keep the stock ROM, always a bit more exciting (and stable it seems, usually) to me than CM(X)

As far as I know, the Australian one will work just fine with AT&T or T-Mobile (no 3G on T-Mobile unless you're in a refarmed area, though). Worst case, it's locked to Australian bands, and you need to get an unlock code to make it work internationally. The reason the Verizon ones are locked for US bands is because Verizon doesn't want you buying their phone and then switching to their competition. Telstra obviously doesn't have the same problem, since they're not competing with AT&T or T-Mobile. Of course, what I'm saying isn't guaranteed to be true, since I don't have an Australian M myself (but I'm trying to decide whether to import that one or the RAZR i). I'm like 99% confident you wouldn't have any issues, though.
The developer edition does not work on AT&T or T-Mobile, either. We should be able to keep the stock ROM. That's how it worked on my Droid Pro and other Verizon Motorola world phones. We just flashed a file that modified the baseband. There was even a file to flash that would return the baseband to stock. ROM flashes didn't affect the baseband once it was modified.
What I'm wondering is if it may just be possible to take the Australian radio and flash it to the Verizon M to make it work on our GSM networks. That would pretty much disable the CDMA radios, but we wouldn't need them anyway. I think some of the previous phones have gotten around the band lock by flashing a Chinese radio, so it seems like the same concept could be used here. I'm nowhere near smart enough to know how to do any of this, though. All we can do at this point (well, me anyway) is just let Team Black Hat and other Motorola developers know that we are patiently waiting for a solution.

Looks like I wasn't far off with my hypothesis. If the community can provide the radio image, we should know pretty soon whether it would work on the M or not.

It also works on the stock unrooted and unlocked Dev device so it should work fine on the stock locked bootloader devices.
Right now it appears to break eHRPD authentication when using a VZW LTE SIM with AU radio image. GSM service is fully functional with no modifications except the AU radio.

Well then...that pretty much settles it. I will be buying a Verizon RAZR M...Dev Edition if I can find one for a good price, or if not, a regular one. I hate that Verizon logo, but I'll save a couple hundred dollars by just dealing with it.

I've been searching for a way to buy this awesome phone in a *truly unlocked* state (bootloader + carrier), and it seemed to be, before now, that my best option was to get the australian one (it also doesn't have the ugly verizon logo on the front But, it's very hard to get it from here in the US, so getting the verizon dev edition and reflash the radio may be better. I'm currently with T-mobile, yes I know about the refarm ... I'll deal with that.
So, does anybody have a link for said radio image? freak4dell, have you gotten yours and tried to flash the radio?
Thanks, you guys are awesome!

Nope, haven't gotten mine. I'm out of the country until mid-December, so I won't be able to get my hands on one until then anyway. I am keeping an eye out for deals, though, so that if I see a good price, I can buy it and have it waiting for me.

Let me know if you find a good deal (actually, any deal at all) for non-verizon razr m! I've also been looking on australian ebay, there are a few auctions for the telstra razr m, but they don't ship overseas...
But back to topic: are the image files in these two following posts any good to flash the radio, or do I need anything else, like a complete telstra fastboot image, or something like that (re-noob-alert: I'm a dev, but I've never messed with phones before):

Note: I haven't gotten any phone yet, just gathering all the pieces together before dropping the cash

No need, I just ordered my razr m developer edition from motorola.com We'll see how fast I can void my warranty
Speaking of which: do I need to unlock the bootloader (and void the warranty) to flash the radio? My understanding is that, since it's signed by the manufacturer, it should work without unlocking the bootloader. That way I can use the phone for a while and return it if it has any problems. Does anybody know?

[Q] Milestone 2 (GSM) on At&T - 3G Works?

So, I was about to buy this phone and use it on At&t in the US, but as I was looking at the ebay listings, I noticed that some of them stated that It does not work GSM with at&t.
I'm not very tech savy, but I find hard to believe that such an advanced phone would have this problem. Can anybody that tested it, shine some light on this for me please?
Thank you
It has the hardware to support it but it's the software that verizon has locked down to not work with any other carrier in the USA
In normal gsm phones you simply need an unlock code for the phone to work with any other carrier then the one it's meant to work with but in this case even after you give the phone the unique code it still won't work with att or Tmobile in the USA so we are looking to see how to disable the lock on USA bands on the phone but it seems not many people have made much progress
Thanks for trying to help, but that is not what i'm asking
I know it works, but everybody says it doesn't work on 3G, just on EDGE.
here's the response I got from an ebay retailer
"This version will work on the AT&T GSM network, however, will not work on the 3G network, only edge.
Best regards,
Communication Telecom International "
AT&T uses 850Mhz and 1900Mhz for the 3G frequency bands and it does support it in the hardware as I was saying, its just that nothing at this point will work not even EDGE because the USA lock overrides anything AT&T uses.

You are confusing the Droid 2 Global with the Milestone 2. Two different phones here.
the milestone2 should have the right hardware to connect to att 3g sorry for the confusion
The Droid 2 Global and Droid Pro also have the hardware to support US GSM bands but it has been disabled in the radio. This is not software, so to speak, but rather hardware configuration.
If you know where to look you can fix this problem.

feel like sharing?
i think he is messing look at the username.
Don't hijack the thead!
OP asked about Milestone 2, not Droid 2 Globlal.
So - to address OP's question - yes - Milestone 2 currently on sale in most places is the EMEA model (Europe/Middle East/Asia), which has 900 and 2100 W-CDMA bands only.
Based on the official page from Motorola here, Milestone 2 A953 has a version with W-CDMA 850/1900/2100 MHz which are the bands used primarily in the Americas (850 and 1900) and Australia (850/2100). There was an article the phone is coming to Argentina before Christmas, so it may start showing up quite soon.
If you want US 3G support from Milestone 2, you have to wait for one of these to emerge. Sure enough it will not have any restrictions against US GSM/WCDMA operators (MCC 310) like the Droid 2 Global (currently) does.
I am not "messing". I cannot post external links of proof because I have too few posts.
I also do not wish to SPAM your forum out of respect for the rules.
Search for droidbandunlock on Twitter for more information.
thats sweet then I saw the video, I have a D2G and bought the phone for this purpose, where will the release be?
They inted to sell it as a servce. It definitely works...we were early testers and I have been trying to help them get the word out about it. These guys know what they are doing and what the value of this exploit is.
well sure but I'd like to know about it asap I've been stuck using this on wifi only :/
I'd pay about $10 for it

Those bast*rds!!! How dare they know what the value is and not give it away for free!!!
I am just kidding
People sell unlock codes all the time for like 15 bucks so should be no problem for people that have to pay for this exploit...wonder if it is the same one I found
This may not be the best thread to continue this discussion. My apologies for the hijack.
I am most interested in seeing what you have found, but from what little reading I have done in your threads it appears you are working in the system only and not modifying the radio.
If that is the case, then our exploit has nothing in common with yours.
Do you have any evidence of it working with US GSM bands on AT&T or T-Mobile?
Perhaps we should start another thread, but we will not be revealing the precise nature of our method for obvious reasons.
Our method makes no changes to the system and leaves no trace of itself anywhere that can be accessed on the device itself beyond the ability to use the US GSM bands.
sorry to interruput but i think this is the only way to talk to you unlocker but about what will the price be and where can we find more info about release dates and downloads etc.? i found you on twitter and asked a few questions but there still isnt much info
I have to modify system because in my ROM (Fission) the packages that handle sim card functions do not work without some "blur" components so thus the need to modify my system
I have pics and a vid ready to go for when I was going to sell my service. I am not trying to nor am I going to compete with you guys or from TBH. P3Droid and Gweedo have been nothing but really friendly with me and to be honest; I would rather not deal with the headaches that come with selling a service on this forum and/or many others. I already went through and going through hell for the way I handle Fission ROM Manager and really don't want any more of that crap...I would rather continue dev work on the ROMs and some other apps I have been working on
I won't get into how my method works for the same reasons that are very clear too but if you want to discuss anything in private feel free to message me or hit me up on Gtalk.
Did you guys release your method yet? If not when do you plan on doing so? I would like to prepare Fission for users who will need to unlock or do use their SIM cards...

Thanks Angdroid for ur hard work. Been following u for some time, hopefully u can release SIM package for D2G Fission soon.
Could anyone running Fission ROM try to switch to GSM mode from *#*#4636#*#* menu? I know you can switch to GSM from there on the original ROM without having to go to settings/wireless/networks/etc As it is standard Android tool, maybe that could be used to switch between the two radios until AngDroid figures out how to make it nice. Hope it works though.

[Q] AT&T (G900A) - Did I screw up by buying this one?

I can't seem to find any legitimate way to root my G900A from AT&T.
I was with Sprint with my S4, and never had an issue. I made the switch to AT&T before buying the S5.. Was that mistake?
In all the threads I've combed through here there is one common, glaring, issue.. The G900A is not included in the supported devices.
Am I missing something obvious or am I screwed? Or am I just looking too soon?
Already gave the S4 to my daughter.
Thanks for any information or insight.

Try to talk with a recovery developer to check your partition table.

I'm sure eventually a root method will come about for that model. Unfortunately tho, the vzw & att models have a locked bootloader and most likely locked down with knox as well and currently no way to boot custom recoveries or kernels.

@PlayfulGod is absolutely right. Even if an exploit is found for the AT&T or Verizon models, it is unlikely that you'll ever have full root access - thanks to the combination of locked bootloaders, KNOX, and SELinux.
Check your contract - most carriers have a 14-day "buyer's remorse" period in which you can return your handset. You might be faced with a $35-$50 "restocking fee", but depending on how desperate you are for custom ROMs and/or Recovery, it may be worth it to you. Please note that your carrier may try everything they can to stop you from leaving (in terms of talking you out of it). Your contact with AT&T should also have a "back-out" period of 30 days (unless that's changed recently).
Couple other notes:
1) That's the primary reason I switched from AT&T to TMO when I jumped from the S4 to the S5 - I was sick of locked bootloaders. Otherwise, I really just like TMO a lot more as a company, including some of their political standpoints.
2) I've heard of several people now buying TMO S5's and taking them over to AT&T. It's a lot of money up front, but might be worth it to you.
Good luck.
Thanks guys
Thank you for the informative replies. They confirmed what I had already gathered, piece by piece, in a decent comprehensive manner so I appreciate it.
Unfortunately, this time around we gamed the system a bit and went in on this as a 'group' for the services and phones. As far as I can tell, as an individual, I don't have any options of returning the unit in favor of moving to another provider.
Besides that, I finally have good service where I live. I am in the middle of a city but my actual home was in a crap spot with Sprint. After doing research we found that we'd all have great service with AT&T. If the trade-off is no root, so be it I suppose. (Though I have heard that T-Mo has the same service in the same areas due to using the same connectivity)
The knox deal doesn't concern me so much.. This may be a bit cocky (and a little stupid), but I have yet to have to replace a galaxy since they started putting them out *knock on wood*. But it sounds like that's only one issue in a sea of others.
Long-winded story short, Thanks guys. I am much more informed on my situation than before. :good:

I expressly bought a G900W8 model because of the locked bootloader issue with AT&T. I've come from Verizon on the S4, and I wasn't doing the whole locked thing again - it was annoying and I just wasn't going to have it. What I did was buy an S5 from AT&T on a $25/month installment plan, turn around and sold it on Swappa for full price, and bought an unlocked W8 model the same day. I payed virtually nothing except shipping, I get a nice unlocked phone ready for AOSP when it comes out, and I didn't have to pay the ridiculous $650 price for what would be essentially a developer unlocked phone.
If your phone is still new and you think you could sell it and get mint condition pricing on it, do your research on the G900T model. That's TMobile's phone, but it has an unlocked bootloader, can be rooted/flashed/whatever you like, and if I remember correctly (please someone correct me if I'm wrong), it works on all the bands that AT&T does and will be virtually the same as far as mobile data goes. If you already have your service activated on your current AT&T phone, you can literally just swap the SIM card out and you shouldn't have any issues after that. There might be a little caveat as far as having an AT&T SIM in a Tmo phone, but as far as I've read on the forum, this is very easy to get past; you may very well not have any problems whatsoever.
You could look for the W8 model, which wouldn't have any carrier branding on it, but those were hard to come by for me on Swappa, and the unlocked listing the main page gives you is for a phone that doesn't support 4G.
So like I said, if you think you could sell it, and you find a good listing on Swappa for an unlocked phone, I say go for it. Having an unlocked bootloader is going to put your device in a good place as far as updates go, and once developers start pushing out polished custom ROMs, you'll be happy to use your device for longer than the year's use that is generally expected.

What LTE bands does Sprint HTC 10 have?

I can't find any definitive answers on this. All I know is the minimum is 25, 26 and 41 but it'd be nice to know the full list. I travel internationally and without other LTE bands like band 7, it makes it tough to use it anywhere outside the US.
EDIT: Someone answered this question in another thread but it would be good to get screenshots to verify this.
m03sizlak said:
LTE Bands: 2 / 4 / 5 / 7 / 12 / 13 / 25 / 26 / 41
I've heard that the FCC filings show that the Sprint variant is not capable (tested or approved) for GSM or WCDMA, which is kind of disappointing since I travel a lot in Canada. Any confirmation on this?

This list of bands is a little better than both the Sprint variants of the LG G5 and Samsung Galaxy S7. If this phone can be unlocked, you at least have a way to go abroad and use LTE connections in much of Europe and elsewhere. Band 7 is the most common band in the world from what I understand.
I'm curious about this comment about GSM and WCDMA. Hopefully someone can verify this one way or another.

If you plan to travel outside the US during most of this time, your best options are to sell your HTC 10 and get one of the few unlocked flagship phones on Sprint's networks, assuming you want to stay with Sprint.
Here are your options:
Google Pixel
Samsung Galaxy S7 SM-930U
Samsung Galaxy S7 SM-935U
Nexus 6P or 5X
Motorola X Pure Edition
Apple iPhone
Here's a full list as of February 2017 of radio unlocked phones compatible with Sprint.
There are other unlocked phones that are not compatible with Sprint because CDMA and LTE bands are crippled or missing.

Here's a full list as of February 2017 of radio unlocked phones compatible with Sprint.
There are other unlocked phones that are not compatible with Sprint because CDMA and LTE bands are crippled or missing.

Thanks for the response. The thing is I'm not on Sprint and have no desire to be. I won't be in the states long. I bought the phone thinking that like most, it could be unlocked and used as needed wherever I travel to. I knew it wasn't unlocked but figured I could do it myself. Well, I've tried a number of times, and keep having an issue with the radio. Can you explain what you mean by bands being crippled? What I'm trying to find out now is whether it's possible for me to get this HTC10 completely unlocked. I think I've done everything right but maybe not. I'm kinda desperate at this point. I love this phone. And if I have to I'll return it and grab another that can be unlocked but I just have a hard time believing that the phone can't be unlocked. It's a strange concept for me. Any help or info would be appreciated.

First, go go Google and look up what LTE bands are.
Crippled LTE bands = the hardware inside the phone will not allow certain LTE bands to work unless physically altered. It doesn't matter which ROM you install, you will not unlock all the LTE bands without physical alteration. https://www.quora.com/Does-installing-different-rom-change-LTE-band-frequency
So no, HTC 10 will never be completely unlocked. Look at the list above and buy one of those phones if you want a completely unlocked phone.

I'm not sure I fully understand. Yes, I know that different chips have different bands that they work with. So, what you're saying is the Sprint HTC10 variant uses either a different chip or has some sort of other hardware configuration that is incompatible with GSM and the wider LTE bands and that no matter what I do with this phone I'll never have a truly unlocked phone? That's what I have understood, so my best option is to send it back. Ok, I get that. But I have read across tons of forums and threads of people who unlocked their Sprint 10s and are able to use them on other non-cdma carriers. So, how does that work? Are all the Sprint 10s the same or are some more limited than others? Are you essentially saying that i would have to get an unlocked/dev edition of the htc10 to be able to use GSM in other countries?
Sorry if i'm asking stupid questions here, I'm just trying to fully understand this. Thanks again for helping me out on this.
If anyone reading this knows better, please feel free to correct me.
This is my understanding of LTE bands and CDMA/GSM radios.
Phones like HTC 10, which are locked, include hardware that are built for specific usages. Prior to HTC 10, HTC phones built for Sprint's CDMA radio were specifically built to lock out GSM radio signals and most other LTE bands using the hardware. This means you'd have to open the physical device and modify the wiring inside the phone in order to allow other signals to work.
As of HTC 10, the locks are supposedly now just software based but I haven't seen proof of that. What this essentially means is that you should be able to unlock the bootloader and flash new Roms that could allow the GSM radio to work universally. However, lots of people are having issues with it. Here's one story of someone who was mostly successful but still had issues:
https://forum.xda-developers.com/showpost.php?p=68960210&postcount=47
Read through the thread above and you'll see a lot of people having issues trying to fully unlock the radios and LTE bands for this phone.
If you ultimately don't want to be on Sprint anyway, I think you really should consider getting something already unlocked that can universally work anywhere. And lots of interesting non-Sprint compatible phones like OnePlus 3t (among the others on the lists I provided) are already unlocked and have a lot of good capabilities and would work great anywhere. The Pixel is one of the best devices out there and the camera is amazing from what most people say.
So I think your options are limited and I'd highly suggest you consider getting a Pixel or something else already unlocked.

They are software based. I have unlocked AT&T bands on my Sprint variant, 2 actually , and they worked perfectly fine. I would show you proof but I am back on T-Mobile which the Sprint HTC 10 already has LTE support for by default.

Should I leave it as a Verizon variant or convert it?

Hello,
I just moved back home to Guam a few weeks ago from Colorado and I am wondering how I should go about getting service in Guam.
After I pay off my Wife's and I services with Verizon I want to try and connect it with the carriers here. To my understanding, after I pay Verizon the early termination fees etc, the phones should be unlocked*carrier unlocked*?
The phones in question are the HTC 10*mine* and S7 Edge*wife's*, we spoke with Verizon before we left, they told us that the phones are unlocked already and wouldn't have any issues using other carriers.
Should I change the HTC 10 to the Unlocked variant is this even possible? I've read about unlocking it to T-mobile or ATT etc so should I leave it and see what my local carriers can do or should I get it in an unlocked carrier state?
Before we left I used a Sprint variant of the M7, lots have changed since then, I didn't have to do anything to change the MID etc, I was sorta gimped on Data connection, but that was a few years ago, NO 4g LTE, but now the local carriers are on it.
Thanks for your time
If you stay with Verizon, keep the stock software. Also you're already sim-unlocked.
If you change to a GSM carrier, not sure the VZW software will work or not but you can definitely "convert" it to the U.S Unlocked version. That's the easiest/safest way since both phones have the same MID. You'll need S-off ($25).
I am S-off already.
Would being U.S unlocked be a viable option to not have issues trying to connect with local carriers?

First, great info above me. 2nd, you could actually go ahead and superCID and run latest 1.96.617.20 US Unlocked RUU. I'd say the best method is to try them out, RUU or firmware. If on a custom ROM and say chose VZW, you'd have to flash again and chose US unlocked. If you are on stock ROM then I'd try and see if it works as vzw says. If not I'd flash The Us unlocked firmware (modified for vzw you may need the radio.img and cardio.img that is normally removed). Best of luck my friend. I hope all goes well!
Will I have issues flashing viper after SuperCID?
OR should I go down to my carrier and try my luck as the device stands?
Thanks a lot!

No issues at all. Supercid, basically makes it so you can flash any firmware and other things like RUU from other carriers like us unlocked -- (so make sure you know what you're flashing!!!) .
I'm not sure of your carrier or what they'd say. I'd honestly play it by ear and see what happens. I have faith that with the 10 you will be able to get everything working; although I can't say for sure.

I'm using a Verizon phone flashed with Unlocked ruu on a GSM network. The conversion improved the phone for me. Better reception in my area, able to connect to more lte bands, txt msgs come/go faster, and the initial connection to the network after boot up or getting outta airplane mode is much faster since I got away from VZW stock software. Also you get OTA updates as they become available, and you don't have to deal with Verizon's worthless software modifications like no battery saver mode, Wi-Fi notifications, etc if you're gonna stay stock.
Flashing the Unlocked firmware is your best bet. The only thing I'll add is that if possible find out what bands are being used by the carriers over there, and see if its compatible.
HTC 10 Unlocked Band Support:
LTE Bands FDD 2,3,4,5,7,12,13,17,29; 2G GSM/GPRS/EDGE - 850/900/1800/1900; 3G UMTS - 850/AWS/900/1900/2100; LTE - FDD - B28/B12/B13/B17/B29/B20/B5/B4/B3/B2/B1/B30/B7.
I want to convert my verizon htc 10 to international version
Guys, do you know how can i possibly convert my Verizon HTC 10 to works the same as the global unlocked phone? I'm so sad with the verizon version, I got weak signal in my country and barely reach to 4G LTE network. Most of the time I can only use 3G and some features also not work I'm trying to read lots of forums and watch youtube, but still couldn't get what I want! Plz let me know.
Thanks in advance :fingers-crossed:

Okay I am trying again now...
It's going further than it did the other time..
It gave me error 155 and 170.. even with a full battery...
So I can just RUU the U.S Unlocked version and and try and use the radios, if not I can just flash back the VZW RUU with no ill effects?
SuperCID to 11111111....

If on Verizon you won't get any service on unlocked without Verizon radios. Why not just flash a custom rom?

Nothing preventing you to convert from VZW to U.S Unlocked, as long as you're s-off. I'm running Unlocked Oreo on my VZW variant.

US996-> On AT&T or Verizon

I'm considering purchase of a US996. I'm considering this model as I may want to change from AT&T to Verizon. Data from AT&T where I live is VERY slow.
At any rate, I would like to hear from folks with this model on each carrier, and if all seems well for you or not.
Any input appreciated.

WETA Rom is for 918...So it works fine on the 996 then I guess.
Is it generally expected that you can put 918 Rooms PM the 996?

Actually Weta Rom is for the 996 as welll. Don't try to put a rom for another device on it lol.

Activation/IEMI setup
Did you have any issues getting Verizon to get the 996 working? I've read about issues with other folks (likely other phones) getting them to recognize / setup the IMEI on their network.
Weta Rom
I've read a lot of the Weta thread. Being totally unfamiliar with the V20, I can't relate to the 'improvments' of the ROM.
Can anyone give me a few points about the benefit of changing to Weta from stock?
I had no problem getting the nano-SIM card from Verizon. Then the only carrier related problem was getting Advanced Calling to work. The bottom line there was to turn off WiFi when you call Verizon to have AC enabled.
Getting the 996 bootloader unlocked was a real pain for me but I think the problem was PC related. When I finally got it to recognize the phone in adb mode all went well. I would advise to unlock/root right away as the process completely wipes any changes you have made.
My overall experience with the 996 is that it is a fantastic phone that I am very happy with. I thought nothing would be able to top my G3 vs985 but I was wrong. I was worried about the size of the 996 but am totally used to it now. Enjoy yours!

I really appreciate your feedback.
I'm wondering one thing related to rooting and warranty. Of course, LG voids warranty if it is unlocked. I see folks posting about restoring to complete stock in case of warranty needs. But, from what I can tell, the only way to unlock the bootloader is via the LG site, and it looks like you have to provide phone info...so they would know you are unlocking the phone. Seems to me it would then be flagged as voided warranty.
Any input on that?
Since the "dirty" exploits unlock the bootloaders of carrier branded and usually cheaper variants, I assume you bought the US996 for its LG sanctioned unlock ability and were willing to forego any warranty. I advised unlocking right away but if you don't personalize the phone very much at first, you may want to wait a week or so to get by the infant mortality period. I waited a month. My phone had upgraded to US99610f before I unlocked it so that was not a problem.
The LG official unlocking process inserts a nag screen at boot up that warns that the phone cannot be checked for vulnerabilities. I don't believe there is any way to remove this even if you somehow are able to get the phone in otherwise original condition - but I may be wrong. I don't know what the "dirty" exploits cause, if anything non-stock, on boot up. If warranty is important to you, check out the dirtycow exploit to see what you can find out about completely reversing the unlocking process, including any nag screen.
The only things I hope come along in the future for this phone are the Xposed framework and a mod to enable fm radio, assuming all the necessary hardware is present. Then I would have a perfect phone instead of nearly perfect.
The main reason I am getting the 996 is so that I can put it on either Verizon OR AT&T if I change my mind on carrier.
I haven't had to use warranty often. I may check into 'insurance'.

Well I know the unlocked version doesn't because that's what I have. As for the carrier models, you'll have to check each one individually and make sure. I'm not positive that all of the carrier models have it, I think maybe one (Verizon?) has it disabled. Could definitely be wrong about that though.
Makes literally no sense why they wouldn't include FM on the unlocked version...
