ROOTING Aquos Crystal 306SH:
This thread is for 306SH ONLY.
Please DO NOT post 305SH information.
305SH has different programming & will confuse people.
Several people are working on rooting 306SH but without help from experts like Chainfire or Cyanogen (or a change of attitude from Sharp),
306SH may not be rooted until we have flying solar-powered cars.
1/28/2015 note to person who keeps posting root info (likely fake) and asking for money in advance:
You keep posting, we'll keep deleting your posts and may BAN you from XDA !
2/14/2015 UPDATE: The BEST thing I can say about the 306SH I formerly owned, is that I sold it on eBay 3 days ago for $139 ! It was in 100% flawless condition. Sorry people, I gave up trying to get ANYONE at Sharp to provide any help in rooting this phone. On the flip side, My Sony Smartwatch 3 has already updated itself to Lollipop 5.01 and Sony is expected to release it for my Z2 in the next 30 to 45 days. Some manufacturers know how to treat their customers and win more customers (unlike Sharp).
Sharp Aquos Crystal is an amazing phone for only $150 US.
However, it needs a way to unlock it's true potential and a way to install updates without bloatware.
You CAN switch from Boost Mobile to Ting in less than 10 minutes & save LOTS of money!
Ting uses the same Sprint network so service (signal strength) will NOT change by moving to Ting.
Switching to Ting is fast & as easy as it gets. Only $6.00/month if you NEVER use the phone.
I'm now using mine as my emergency backup so unless I need to use it, I'm only paying $6/month ($6.89 including taxes).
All you need is:
1. Your IMEI # < Can also be found on bottom of Boost Mobile package
2. ISID # < On bottom of Boost Mobile package
3. Credit card < Ting bills at END of each month, not prepay like other no-contract services
4. Bring your own number (port in) or let Ting choose a number for you from ANYWHERE in the USA
(choose an address in any city & state, it offers appropriate area codes + number).
NO SIM card is required.
Ting can also be used internationally on some GSM networks. INSTRUCTIONS
Note: Switching to Ting does not change or remove the Boost Mobile 4G boot animation.
WARNING: Ting has a bug in their billing system and even though your phone/text/data usage may be ZERO, they may try to bill you for usage. This has happened to me repeatedly so if you switch to Ting, be prepared to watch your monthly bills for errors.
Here's what else I've accomplished & learned using the 306SH since October 16, 2014:
Thought I had root using Kingo but it wasn't because SuperSU is not working & Root Checker app says we do not have root.
I was tricked by Kingo. Per feedback from Kingo, they are "working on it."
This means that many apps requiring root will not work at this time BUT may install and seem like they are working perfectly.
Here are step by step instructions of what I did which lead me to believe we had REAL and FULL root:
Note: You may see different results if you have or do ANYTHING differently than I did.
I will not be responsible for any damage (bricking) to your phone or respond to messages as such, so proceed at your own risk.
All of this applies ONLY to Sharp 306SH on Boost Mobile.
I do not have a 305SH and there may be undiscovered difference(s) on the Sprint or Virgin models.
1. I am running Windows 8.1 Pro 32bit with all updates.
2. I have Sharp Aquos Crystal connected to a USB 2.0 port.
3. I installed the stock Sharp USB drivers, specifically android_winusb.inf dated 8/25/2014.
4. I activated Developer mode by going Settings>About phone>press Build number until it says you are a developer
5. Go Settings>Developer Options>put checkmark in USB debugging.
6. Go to Kingo's latest version 1.2.6 download to download app named android_root.exe 18,018,600 bytes size.
7. Run android_root.exe while phone is connected via USB and USB debugging is ON (checked).
8. Kingo app should say that phone is connected. If not, you have a problem that I can not diagnose for you.
9. For the next several minutes it should repeatedly scroll "Downloading requisite dependency files ... Waiting for device ...".
10. Phone should reboot by itself. After it reboots install and try to run any apps that normally require root.
11. As of now, I have Root Explorer working. I can see and access ROM folders and files including system, but not Data folders.
I tested Titanium and it is NOT working. Root Checker says NO ROOT. Busy Box says problem may be related to SuperUser or SuperSU not having proper permissions.
This is ALL I know for now about rooting Boost Mobile 306SH . If/when I learn more, I will post it HERE.
UNLOCKING I spoke by phone with Boost Mobile on 10/24/2014 and was told that Boost will NOT provide unlock codes for ANY of their phones. Then I spoke with Sharp Support at 844-742-7751 and asked them. While speaking with Sharp, I also asked about unlocking the bootloader and when Sharp may be posting what developers need so we can create custom ROMS and possibly root this phone. I will post the response from Sharp to all these questions as quickly as I receive it/them.
Unlocking normally means you can use it on any other similar network. In this case, the 306SH is CDMA which means we would be restricted to Sprint, Boost, Virgin or any other CDMA network in the USA.
GSM Use. It might be possible for us to also use our 306SH phones with GSM networks such as Tmobile or AT&T in the USA. In Japan, the same Sharp phone is known as the 305SH and is set to work on GSM networks so, common sense says GSM use in USA might be possible if/when an XDA developer modifies the code for us..
HOW TO UNLOCK GSM phones (such as the 305SH)
1. You obtain unlock code from whomever sold you the phone and is currently providing service. From time you request the unlock code, it may be up to 2 or 3 days before you receive an email with that unlock code. When you request the unlock code, you will need to provide the IMEI code to your current service provider. WARNING: There are MANY scam artists (websites advertising unlock codes for a fee) and many of them will NEVER provide you with an unlock code that works.
2. You install a new SIM card from whatever new service provider you want to use. Example: If you obtained unlock code from Sprint and want to switch service to Virgin Mobile, you insert a Virgin Mobile SIM card.
3. Turn on the phone and it should go to the unlock screen.
4. Enter the unlock code.
I did this on my Tmobile Galaxy Note 3 at it worked perfectly.
NOVEMBER 24, 2014 UPDATE: NOBODY is even close to rooting the 306SH. Last night I even tried using Chinese VRoot V1.7.3 ... just another waste of time.
DECEMBER 6, 2014 UPDATE: I switched from Boost Mobile to Ting: On 10/14/2014 I tried to order my 306SH from boostmobile.com website because it included 1 month of FREE service (up to $50). Website was NOT working so I phoned my order and chose $35/month plan. I was supposed to received $35 credit within 14 days after 10/16/2014 activation. Boost failed to issue $35 credit as promised. 11/24/2014 I phoned 866-402-7366, spoke with Raine. She had to submit a special request to get my $35 credit.
Then I received a message saying thanks for paying Boost Mobile another $50 (which I did NOT do) ! Days later, I received a message from Boost saying that instead of refunding me $35 for month of service that should have been FREE, they would give it to me NEXT month. Sorry Boost, too many mistakes. I lost faith in "Worst" Mobile and switched to Ting which will also save me up to $348 a year!
FEBRUARY 2, 2015 UPDATE: I give up. Zero cooperation from Sharp and after 4 months, NOBODY has found a way to root this phone. In addition, Ting has continued billing me for service I did NOT use! Bottom Line: I just notified Ting to terminate my service and I am selling my 306SH on eBay. Winning bidder will get it in 100% perfect condition with all the unused accessories and paperwork. As I type this, I am reminded of Murphy's Law. The minute I sell this phone, it would not surprise me if some on this thread finds a way to root it! Good luck y'all !
Simple click of your "Thanks BUTTON" is ALWAYS appreciated so I know I'm not wasting your time or mine!
I do not accept, want or need any monetary donations from anyone.

Since surviving through 4 defective original iPhones in a row, I've purchased, rooted & customized over a dozen Android phones and tablets.
The 306SH is least expensive smartphone I've ever owned & runs great. Sony Xperia Z2 is my daily use smartphone (better camera and root is available now),
If/when someone successfully roots 306SH, I will update this post.
That sounds like a good news.. but does unlock means you can use it w gsm network?
sounds good .

Aquos crystal
Glenn , does this mean i can use a cdma sim card in india which uses the same frequency as the boost cdma does ?, just purchased one for use in india
HI Glenn,
I've tried it w. the sprint model and it doesn't do anything with tmobile sim. i saw a video on youtube where the guy put an att sim into the booster version and he was able to use the 3g and outgoing call but not incoming..
i have no way of validating his video but he was using boost service .

UNLOCKING THE SHARP 306SH which is CDMA:
Net10 website said that my 306SH is compatible so I invested $5 on a Net 10 BYOP Kit. I discovered that there is NO SIM card for CDMA in the kit! Instead, the kit provides instructions on how to switch from Boost to Net10. Then I discovered something I've not seen on ANY of my prior smartphones. I removed the BoostMobile SIM card from my 306SH and rebooted the phone. Without ANY SIM card I completed a phone call. However, instead of 4G LTE service was limited to 3G without the SIM card installed. When I reinsta;lled the SIM card, it went back to 4G service. Based on these experiences, I now believe that the BoostMobile 306SH may be already unlocked and switching to another carrier is simply a matter of reprogramming the phone with a Net10 activation kit or similar kit from another carrier that can service CDMA phones.
USING THIS CDMA PHONE ON GSM NETWORK. More research on the latest phones, GSM and CDMA technologies today now leads me to believe that we MIGHT be able to use the 306SH on EITHER the CDMA or GSM networks such as Tmobile or AT&T. Here's why....
Many of the 4G LTE carriers are using the same frequency band for CDMA and GSM
CDMA phones DO NOT require SIM cards BUT the latest batch of phones (including our Aquos Crystal) do have SIM card slots for the very purpose of being able to use them on GSM networks).
I installed an AT&T GSM Nano SIM card in my Sharp 306SH and it did not act like I had done anything bad. I did NOT activate the AT&T SIM card because I do not want to leave BoostMobile at this time nor pay for AT&T too.
OCTOBER 27, 2014 UPDATE: Just heard from Sharp about unlocking 306SH.
Sprint will commence offering unlocking in February 2015 and current policy is posted at http://www.sprint.com/legal/unlocking_policy.html
Sharp/Sprint is currently discussing unlock policies with Boost, Virgin and Alliance which may result in similar policy OR something different but has promised to announce final decisions no later than February 2015.
In the meantime, I advised Sharp of my own findings which indicate that the 306SH sold by Boost Mobile may already be unlocked and capable of GSM service. Sharp's response was no comment. It seems that the only way we all might find out is if one of us installs an AT&T or Tmobile SIM card into a 306SH and tries to activate it with one of the GSM carriers OR installs a SIM card from Virgin Mobile to activate their service. After I get my free month of service from Boost (part of the $149.95 promotion), I will try to switch from Boost to Tmobile because I believe Tmo has better coverage area (and currently offers similar prepaid plans).
If anyone finds anything to contradict this, PLEASE let me know so I can update this post.

I asked my seller, in Japan, for my 305SH, and according to his answer, SoftBank don't want to give unlock code yet.
Update to everyone
PEOPLE: I think the REAL problem here is that Sharp did NOT plan ahead and decide upon unlock terms with each carrier
BEFORE they started selling the 305SH and 306SH phones.
To clarify, 306SH from Boost Mobile (and likely Virgin and Sprint as well) works on 3G without any SIM card at all.
Take the SIM card out of your phone and see for yourself !
When I spoke with Sharp by phone today, the agent told me the SIM card is only there to store data, which basically confirms this too.
As far as use in India or anywhere else other than USA, someone from that country will have to provide 305SH or 306SH information because
I am not planning any trips outside USA any time soon.
Glenn
The sim card is only for the 4g service.
If you remove the Sim then the phone is restricted to 3g service of the same service provider.
If you add sim card of t mobile, at&t etc then the data which you are using if of boost mobile only.
The sim card slot is not reading anything from the Sim card.
Only thing which needs to be verified is whether the phone supports cdma service overseas or if it can be GSM unlocked.
Testing 305SH GSM in Japan
Could someone with the 305SH in Japan PLEASE remove your SIM card and let us know what happens.
Does it lose all signal or go to 3G?
Thanks,
Glenn

Without SIM Card:
- no 3G with 305SH. no data , nothing.
- we can see all network operators around but we can't connect : "unable to connect to this network at this time" if you try.
With SIM card (not Softbank) we didn't see network operators.
(sorry, I not in Japan)

Thanks. This tells me that when the Sharp Aquos Crystal 305SH is activated with a GSM carrier, SIM card is being used like any other GSM only phone. This still leaves me wondering if the 305SH with no SIM card could be activated on a CDMA carrier in Japan. If so, logic says reverse might be true with 306SH in USA.
Glenn
Quick question, does anybody know if I can purchase the Sprint Prepaid Sharp Aquos Crystal and just pop in my TMO sim and have full capabilities (phone, 4G, etc)? If it requires unlock, I suppose I can still get it unlocked after 90 days, right?
Sprint to Tmo

OCTOBER 28, 2014 UPDATE:
We CAN use our 306SH Boost/Sprint/Virgin phones with TING which charges based on actual usage for calls, texting and data. The fact that 306SH can ACTIVATE WITH TING is more evidence that 306SH might already be unlocked. Even if it isn't, Ting rates are lower than Sprint, Boost or Virgin if you use your smartphone sparingly. As I was just told during a chat with Ting they "buy access to their network [Sprint] at a wholesale level to provide service."
Aside from the posted usage TING RATES , there is a base monthly charge of $6.
If anyone finds anything to contradict this, PLEASE let me know so I can update this post.

I am a cdma user in china
HERE IS MY opinion .when you take out the sim card it still work with 3G right? if it is. i am sure that they flash the numbers in the NV items and if you can get the spc code . you could use the cdma tools like DFS to check
i think it will shows" NV ONLY" but it is no help for unlock
The reason modern CDMA devices have a UICC SIM is for LTE service only. Unlike their GSM counterparts, the built-in IMEI/MEID/ESN of the device is what is registered with the provider. Until recently CDMA devices did not require SIMs because they didn't have LTE or the LTE UICC SIM was built-in (non-removable). Any CDMA device should work without its SIM for everything but LTE.
This device does seem to be unlocked within Sprint's networks. That doesn't mean it has a GSM radio or compatible with GSM LTE bands. For example, the Boost Moto G could be activated on Ting as well (basically unlocked for Sprint), the bootloader can be unlocked, be rooted, and flash any ROM to it, but AFAIK there is no way to get it on a GSM network - it doesn't even have a SIM card. The Nexus 5/6 are the only devices so far that are completely cross-compatible between CDMA, GSM, and their respective LTE networks.
If I am wrong, and the hardware is identical between the US and Japanese versions, we would still have to get root access first and flash a GSM ROM/radio to get any GSM carriers to work.
Ting definitely does work though and is an excellent inexpensive provider... the only downside is using Sprint's network, but if you are in a half-decent LTE area it is quite good.
Posted this in another thread too but here so more ppl see:
Today went out and bought Sharp Aquos Crystal on Boost with the $100 off deal when you bring your phone number to boost. Got the phone for $50 then took the phone and activated it on Ting. Now Boost guy who sold it to me called and said that they will report phone as lost or stolen. What to do?
$100 off phone at Boost for giving them your #, means just that.

The deal you did is NOT the same as paying full price for the phone and then choosing whatever carrier you prefer.
By giving you $100 off (and as you have stated) you were agreeing to "bring your phone number to Boost" which you are violating by bringing your phone number to Ting.
I suggest you cancel Ting and activate with Boost UNLESS you can totally rescind (cancel) your original deal with Boost.
I am not an attorney but it seems pretty simple to understand why Boost is pissed at you.
They gave you $100 off the phone ONLY because you were agreeing use Boost phone service.
Glenn
P.S. Not sure if the offer is still on but I paid Boost $149 for my phone which included a month of free service (up to $50). I might move to Ting but BEFORE I do,
and based on your experience, I will be sure to speak with Boost FIRST, just to make sure there isn't some small print somewhere that might cause me a problem.
I was curious if anyone had tried dual CDMA carriers on their dual sim G4s. My understanding is that for 3G cdma voice the device itself is registered as opposed to a 3G GSM which registers the sim, so only one CDMA service could be active at a time. Changing to another CDMA carrier would mean going through Verizon's or Sprints's activation process each time you wanted to change to a different sim (this was my experience with a 3 sim adapter). I'd love to hear someone more knowledgeable chime in on this subject and provide some feedback on whether or not this is how it would work with a dual sim moto G4.
I'd love to have dual CDMA sims because I have free service with ringplus (Sprint MVNO) but it's spotty in rural areas, whereas Verizon has the most solid signal in the remotest regions.....however I think it's a pipedream. I am aware that you can do a CDMA LTE sim switch and get data without a problem (I'v done this with a triple sim adapter), it's voice and text that I'm interested in being able to switch to, without having to go through the activation process. And because I need this voice and data in remote areas without LTE, VOLTE isn't an option.
I hope that isn't too convoluted or arcane a question, I realize it's not a common scenario. But with the Moto 4G being carrier friendly to all the north american providers (GSM and CDMA) and having a dual sim slot, it's the first plausible solution to what I'd like to achieve.
Unfortunately, the only G4 models that have CDMA are the US models (XT1644 G4+, XT1625 G4, XT1607 G4 Play, XT1609 G4 Play for Verizon Prepaid), and the US models are only available in single-SIM format.
From what I've been gathering, there are no dual-SIM CDMA phones that fully work with US carriers available yet. The OnePlus 3 comes sorta close, it's dual-SIM and has CDMA Band 0, which Verizon uses in most markets, but at the moment it either works in 1x/EVDO mode for calls/text, or LTE mode for data. However, it's lacking CDMA Band 1 (Verizon & Sprint) and CDMA Band 10 (Sprint), so it's not ideal. It's also lacking Verizon's main LTE Band 13, and all of Sprint's LTE bands.
Slightly good news, though. The upcoming ZTE Axon 7 is dual-SIM and FCC testing indicates that it fully supports all US carriers, including all Verizon and Sprint CDMA bands.

I'll keep an eye on it.
Would the concept work the way I described in the first post though? I'm really curious if the phone would require sprint or verizon activation when switching cdma sims. I don't have a great deal of experience, simply my results with a multisim adapter. I was unable to test the adapter with a verizon and sprint capable phone (like a nexus 6) but tested it with an Verizon samsung s5 using gsm sims and a verizon LTE sim. The gsm sims (various at&t and t-mobile MVNO) were of course no problem, but switching to (or back to) a verizon LTE sim required teh verizon activation process (but not for data, as the LTE was active without activation).
Is it possible to have a dual sim (or even single sim) phone that supports both carriers (Verizon and Sprint) that could switch back and forth, or is the activation process simply inherreient with the way the devices imei's are registered on CDMA networks, and will always be required. For me going through the activation process for Verizon or Sprint when switching sims would simply preclude any practical usefulness with a dual sim cdma capable phone (although it would still have value as a dual sim with a cdma and a gsm sim).
Sorry for the late reply xtermmin and thanks for the info.

I can't speak for Sprint, as I have Verizon, but I do know that they're more restrictive than Verizon.
On Verizon, the only current restriction is a whitelist when you try to activate a SIM for the first time. You have to use a device that's in Verizon's "activation database", typically Verizon-branded devices, iPhones 6 and up, the Moto X Pure, and (at some point, if not now) the Moto G4 lineup. Once you have an activated SIM, you can stick it into any compatible device (be it from Verizon, another provider's phone, or even an unlocked phone that doesn't officially work on Verizon) and you should be good to go.
For example, I've been using my same Verizon SIM that I got with the HTC Thunderbolt (when it launched in March 2011) in numerous other phones (Verizon phones, US Cellular phones, unlocked phones, even some GSM/LTE-only phones) with no need to contact Verizon or use the website or anything. I've been able to just pop in the SIM, adjust the connection method on the phone if needed, and go.
As for your experience with using a dual-SIM adapter on the Verizon GS5, it might be due to the phone going into "GSM/LTE" mode when you insert a ATT/TMO SIM, but not switching to "CDMA/LTE" mode when you switch to your Verizon SIM (thereby only connecting in LTE mode). Might want to try setting it to Global mode (GSM/CDMA/LTE). The Verizon version probably wasn't tested for dual-SIM use, so it might just be the OS not knowing to switch to the other mode, or it might be an issue with the adapter itself.
Regarding an actual dual-SIM device with both SIMs being CDMA, I'm unsure if it causes any issues, as there's been no phone with that ability released yet (technically, someone can try dual Verizon SIMs in the OP3, but the CDMA implementation on that phone looks to be pretty half-assed, so I wouldn't use it as a baseline). Guess it depends on how the SIM slots are setup (if they share the same IMEI, or if they have different IMEIs for the two slots). If they're the same IMEI, I can see there potentially being issues, but if they're different (which should be the case for any modern name-brand flagship), there shouldn't be.
We'll know more once the Axon 7 releases. Unfortunately, ZTE has said that CDMA support will be coming in a software update later, but at least the phone is physically banded for CDMA, so we won't know for sure until then.
Actually the xt1644 have dual sim slots , one is hidden open the phone and you will find it

***voLTE, WiFi calling, Tmobile***
=======================================
(linked from XDA by David Ruddock)
T-Mobile Unofficially Speaks To Us About Band 12 LTE / VoLTE And Unlocked Smartphones,
And Yep It's Still Confusing
-----------------------------------
Yesterday, we published an article asking an open question: what is up with T-Mobile band 12 support being removed from some unlocked smartphones?
Today, T-Mobile contacted us to speak about said article. Unfortunately, T-Mobile was unwilling to provide any official on-record responses to our questions. But after a short discussion, I can provide you some information I have learned on background (journalist speak for "cannot be directly quoted or attributed to anyone"). First:
On T-Mobile, any device on its network with band 12 LTE data support must also support T-Mobile Voice over LTE services and E911.
The E911 part isn't particularly important in terms of the certification requirement - all phones sold in America are technically E911 compliant, because by law they have to be. The problem is that E911 compliance is inextricably linked to T-Mobile's VoLTE requirement for band 12. Without VoLTE support, a device on band 12 service would be unable to make phone calls of any kind if no other T-Mobile band was available (it will not know to fall back to AT&T roaming - the call will just flat-out fail), and that would include making 911 calls, meaning the device would for legal purposes likely be out of E911 compliance, and T-Mobile could get in trouble with the FCC. Not to mention, you could have somebody trying and failing to dial 911 in an emergency, which would of course be terrible. And yes, by removing band 12 support, you can make E911 work, because the phone then has no signal at all and knows to try to roam onto another compatible network (AT&T usually) to complete the call. This is both a safety and liability issue, and it is easy to understand where T-Mobile would be coming from in terms of concern about this - they do have something of a history with E911 debacles. Clearly this is a very real safety concern, and I do sympathize with T-Mobile in the sense that they obviously can't just sit here and do nothing about it. But there are practical concerns for OEMs here - adding T-Mobile VoLTE isn't just as easy as flipping a switch.
In order to obtain VoLTE compliance for band 12, phones must go through T-Mobile's rigorous network certification process (and yes, unlocked phones can go through this certification).
Speaking off the record to one major smartphone vendor, we have learned that there are very real costs and complexities associated with obtaining that certification, and it must be done on a device-by-device basis. Many phone OEMs, then, may simply choose to remove band 12 support from their unlocked smartphones sold in America. This could mean phones like the Alcatel OneTouch Idol 3 (4.7 and 5.5), the Huawei Ascend P8 Lite, the Huawei SnapTo, OnePlus 2, Moto X Style (aka Moto X 2015 PE), Moto X Play, HTC One M9 Unlocked and Developer Edition, Saygus V2, and various imported phones (ie, some global unlocked Sony or Samsung devices) or unlocked branded AT&T phone models may lose band 12 support in future software updates. The fact is, we don't know what will happen, or to which phones, or when. Some manufacturers may choose to get T-Mobile VoLTE certification (Motorola has hinted as much with the new Moto X 2015 PE), but many may also simply choose to quietly disable band 12 for T-Mobile in software updates. Motorola, as we know, has already done this with the Moto E.
It is not clear what action, if any, T-Mobile will take if a smartphone vendor refuses to remove band 12 data support from their device and also refuses to undergo the T-Mobile VoLTE certification process. (Ie, they want to keep B12 data but not bother with B12 VoLTE certification.)
This is basically the kicker. What will T-Mobile do if a vendor says "no way" to dropping band 12 data, but also doesn't want to go through the VoLTE certification process? We don't know. They might not do anything. But they might do something. Again, this is why speaking to T-Mobile about this situation was so frustrating. Not only we were unable to directly quote or attribute any of the information we were provided, but there was also no clarity as to what would happen in the event the band 12 situation comes to a head with an OEM that refuses to "play ball."
It seems unlikely that any OEM would refuse T-Mobile's request here, though, as most of them are also partnered with the company on T-Mobile-branded devices.
We have asked T-Mobile again for an on-record statement about this entire situation, because it would help clarify it immensely. As things stand now, T-Mobile is attempting to put the ball in the court of manufacturers. Which, to be fair, manufacturers do have a role to play here - they have to make the decision to drop band 12 or go through the T-Mobile certs for these unlocked band 12 devices. Or, potentially, just ignore T-Mobile's band 12 requirements entirely and see what happens. Unfortunately, as you might guess, most smartphone OEMs have zero desire to discuss upcoming software updates in detail, or to ever put their product in a situation where it is being highlighted for losing a feature. That makes our job here a difficult one.
We will update you on any more information we receive about this situation, including any response from T-Mobile or potentially-affected device manufacturers we have reached out to.

Offical rom??? if your mean stock rom, yes it possible to have VoLTE, provided your network support!
AT&T claims to unlock their SIM locked device for US networks only, but not Europe?
Hi people, I'm new in US Samsung models world, so I have a couple of burning questions.
Long story short, my friend lives in US, has bought AT&T S7 Edge last year off contract, paid the device fully, so in theory he should be free from their will, except the device being SIM locked to AT&T. Now he has S8, and wants to send me his S7 Edge here in Europe, however upon contacting them about removing the lock, they have claimed that at least a year has to expire from the day of purchase for the phone to be fully unlocked and used globally, and as for now, they can only unlock the phone from their network so it can be used (on all networks) in US only, but it can't be used in Europe (until a year expires which they indicated).
Now, from my very limited knowledge I smell BS here, since only thing they can do is block the usage of certain bands through their software thus limiting usage of the device across all networks, but that can be avoided by flashing a fresh firmware, or better yet U firmware, since I've read that its Samsungs firmware with unlocked bands for a global use.
So, as long as there is hardware capability, they can't limit it really permanently, or for certain amount off time if you bypass that with U global firmware.
Or am I wrong here? Is unlocking through 3rd party websites better solution?

1) As soon as the phone is paid off (no balance owed) and you have been a customer in good standing for either 2 months (post-paid) or 6 months (pre-paid) you can request a SIM unlock code. Yes, this is BS, but it is what it is. Note that it is important to do SIM unlocking BEFORE removing your old device from your account, as you will guarantee a bad time trying to do it afterward.
2) The SIM unlock is global and should allow any APN to be used with the device. AT&T doesn't really care where you use your unlocked device because T-mobile is just as much not AT&T as any European carrier.
3) If you can get it from AT&T for free, why not? Otherwise, get it where you can. So far, every time I have requested an unlock for an AT&T device I have had to escalate, and for some devices they don't even offer unlocks (AT&T branded hotspots, tablets, etc. aren't unlockable through AT&T)
4) Using U firmware doesn't help because it is the baseband processor (and related firmware) that handles network locking. Simply switching to unlocked software doesn't alter the baseband at all. Changing the modem/baseband firmware won't help EITHER, because that processor has it's own non-volatile storage. Carriers take SIM locking very seriously at a hardware level.

1) All those conditions have been met, so there shouldn't be a problem about requesting SIM unlock code, and they did say the phone can be unlocked and be SIM free but it will work on US networks only, and not on European, until 1 year expires.
2) Since the G935A has GSM 2G bands and HSDPA 3G bands, it is already compatible with European bands, or specifically with bands on my carrier here, I don't see how are they going to unlock it to work on US networks but not on EU, that's what confused me. SIM unlock should be global that is how it goes anyway.
3) Yeah that's what I thought, but since they mention limiting the unlock (if it is possible) for US usage only (maybe tampering with the device in hand) it might be better to go for 3rd party unlock.
4) Thanks for the explanation, that seems serious, not sure why so serious though.
Anyway as a conclusion, since both 2G and 3G bands match with my carrier's, if they do unlock the device (AT&T) it should work in EU, despite their claims that it won't for a year? How would they "unlock" it after a year when the device is not in their hands :S
I suggested to my friend to request a code through 3rd party anyway, unlock it and send me the device, since he was already pissed off with the response from AT&T.
I was wondering if there are different version of the OnePlus 6t. I have seen some called "global", "international", or "T-Mobile" version. I am moving from a LG V20, of which there were 5 or 6 different versions depending on carriers. Are all of the 6t's the same? Can I download the updates and not have to worry about messing up my phone? Thank you!
Downloading an update directly from Android UI will not break your phone (unless you have modified system partition)
Just take the global/international version (a6013) from oneplus.com and you'll be fine
There's two versions, international, and T-Mobile.
International and global are names for the same thing. It's the phone directly from OnePlus. It gets updates the quickest and has dual SIM support out of the box. You can get all the hardware versions (6/8gb ram, 128gb/256gb storage).
TMobile version is only 8gb/128gb. Only in mirror black. It comes with single Sim support out of the box. It has a locked bootloader that can only be unlocked if you get TMobile to SIM unlock the phone (typically once the device is paid off, but people have got it done sooner). So far it's only gotten one update and seems to be a few weeks behind the international version. It *might* have software optimizations for T-Mobiles network. (Dual SIM can be done with an unlocked bootloader and running the international software. You can't take OTA updates and must flash manually)
Sales and monthly payments can possibly make the TMobile version a better deal. If you're paying outright and full price. Get the phone directly from OnePlus. The only advantages the T-Mobile version has is the possible network optimizations (not proven, but assumed), and the fact that you can swipe left on the home screen and access Google feed. You can't do this with the default launcher on the International version. But this is a minor issue. There's trade offs with the TMobile version, but it's possible to be cheap enough to make up for the trade offs. You can look at the (Don't buy the TMobile, and Do buy the T-Mobile) threads in the discussion subforum.
Thank you.
My 6t is on order and I plan to use it with Verizon. Thank you for the information.

Works great on Verizon.
Use chat to get them to configure CDMA_LESS or LTE only mode. Took about two minutes for me. Otherwise SMS won't be received.
