H8314 on Verizon: what to do with a Global version - Sony Xperia XZ2 Compact Questions & Answers

Hi all,
I'm brand new to the forum so forgive me if this has been already been hashed. I generally try to do fairly comprehensive due diligence when buying phones but this has left me completely exasperated.
I found out, the hard way, that the H8314 comes in two versions - US and Global; I suspect I ended up with the Global. The hard way was bringing my device to Verizon and after over 2 hours of toil being told the device was "locked". I'm therefore stuck with a useless phone as the global version will not register on Verizon. It does activate on AT&T but because VoLTE is not supported it will downgrade to G3 for voice and calls on those bands are highly unreliable. Anyway, GSM and CDMA will soon be gone so there is really no viable and durable option in the US for this device.
My question is there anything I can try to salvage this phone Is it possible to flash a Verizon compatible kernel that might rescue it? Any other ideas?
Thanks in advance!

[Q] What's the cutoff point for ROMs to unlock the SIM?

OK, so I have an opportunity to get an LG G5 LS992 Sprint model today for a decent price (under $60), with box, original cable, charger, accessories, 2 or 3 cases, looks to be in fairly good condition from the pictures. The girl selling it doesn't know how to answer most of the questions I have so certainly I can't get her to tell me what the ROM installed is by looking at the Settings - About phone info.
So here's my question: been doing some research today into the current situation and from what I gather, Sprint, in their infinite greedy and stupidity as usual, has found a way to block the ability to unlock the SIM for use with other carriers like T-Mobile (my carrier of choice). Apparently this started with ZVC and I have no idea which specific version of Android that is since there's a bunch of them around but I'm going to presume it's at least Android 7.0 Nougat.
I'm going to presume that if this phone does not have ZVC on it then it's safe to also presume that I would be able to do the SIM unlock and make use of it with T-Mobile so if anyone out there might be able to answer that I'd be eternally grateful.
As stated, I have no idea what firmware is currently on the device, unfortunately, I sure hope it's not ZVC or anything later, guess I'll find out later today when I meet up with this person.
Dammit, Sprint, what the hell are you people doing?

LG-G710TM Unlocked by T-Mobile on Verizon?

Purchased from T-Mobile a year ago, all paid off, and permanently SIM unlocked by T-Mobile app (white-listed by T-Mobile so it would unlock). So, the phone is free and clear. I think the answer may be self-evident in the model numbrer, but can an unlocked LG-G710TM work on Verizon? When I pop in my Verizon SIM (from S10), it registers on the voice network, but mobile data won't connect. The firmware (still v8.0.0) is all T-Mobile. Went to Verizon store, wait for the shock and horror, and they gave up after basic settings changes.
Just for kicks, if the 710TM can only work on T-Mobile, that makes unlocking this model somewhat pointless, no?
Thanks for any quick hits.

Back up your phone and flash with G710VM firmware which should allow it to work on Verizon. See link below with instructions.

Starting at post #55 in that thread, it says cross flashing the 710TM will brick it. Gotta ask the dumb question: did you point me there knowing that cross flashing the T-Mobile to Verizon will work or just knowing that there was a cross flashing thread that works for most G7s?
I"m appreciative for the help either way.

I don't have TM version so I was unaware of such restriction. My apologies the method will not work on your device.
If entering the Verizon APN info in (which I'm assuming the employees at VZW tried) still failed to produce results, then yes, you may be out of luck (however you could make use of a prepaid network that uses the T-Mobile bands such as Mint Mobile or sell it as a white-listed phone). This is why there are many of us with LG phones that wish they'd just release one model per device, as the Qualcomm chip used supports a wide range of bands used by various providers.

Looking To Buy This Phone...Need Advice...

I am looking to get this phone and needed some advice. I haven't bought a cellular branded phone for a long while. I usually go with the USA Factory unlocked version. On this phone is the cellular named stamped on the back of the phone? I know the model for the USA Unlocked version is G820QM (with a 7 at the end at times) but it is honestly harder to find. What does everyone recommend on this phone in regards to getting the cellular branded one or should I keep trying to find the USA Unlocked version? What about bloatware with the different cellular branded ones? How is that? Can you get rid of the bloatware? I also like what I call the LG Branded ones as they get the updates faster do they not? Please help me. I am looking for a phone and this one stuck out at me unless someone suggests a different phone with similar specs to this one? Thanks so much! :good:

Unsure where you're from, but stay away from the AT&T unlocked model (my model G820UM), I'm from the UK and ordered one, big mistake, AT&T does not send any update to their phones if they are not using an AT&T SIM card in the US, some users have been successful in updating they're OS, by just using a AT&T SIM card outside of the US, some haven't and I haven't tried it, because I don't want to waste more money on a SIM card when the results are not 100% guaranteed.
There is no way of cross flashing a different ROM, so you will be stuck without updates, until someone finds a way of cross flashing a ROM from an unlocked model. I'm checking this forum regularly hoping some has found a solution, but nothing so far
If you are in the US and on AT&T then it will fine, bloatware (which is a lot) can be removed/disabled easily
Honestly, for the price I paid (£280), I think the Xiaomi Mi9 would have been a better option, similar specs, updates every 2 months and you're able to unlock bootloader, not the best process to unlock the bootloader, but still possible (just need to wait for permission from Xiaomi which could take a few weeks), you'll be missing out on the best headphone jack, better cameras (not by much) and better battery life, for a similar price I think this is the best deal for snapdragon 855 phone.
If you don't mind paying a bit more and want the same features as the G8, go for the Samsung S10.

Yep no luck, I've sold the phone, I was wasting too much time trying to find a solution, so just sold it and claimed my sanity back xD
Going back to the trusty Xperia 5, timely updates and great software and they are going for around £260 so easily recommended.
That's too bad, AT&T must be interfering, because I just purchased an unlocked G8 in Canada, and it updated to 10 over WiFi, before I inserted a SIM from my carrier (Bell Mobility). Phone was not on Bell originally.

Yep, this a AT&T "feature", want updates? Buy at AT&T SIM card and use it in the US, guess they don't want anyone outside the US to use their products, unsure why, but it is what it is...

Is 10 really that big a deal from 9? I have 9 on my phone i could care less if it gets 10 and I am pretty sure it wont , lol
I feel like if we have temp root then it's only a matter of time before we get TWRP and roms. I just picked up an AT&T model for $178. Not sure if it's unlocked, but fairly easy through AT&T. Just worried if we have an exploit, updating to 10 might invalidate it.
I come from PS3/xbox 360 hacking, haha.

How are Consumer Cellular Note 10 Carrier Locked? Help Needed

I have a Note 10 Plus N975U1 that was sold as a Consumer Cellular device through Target. The phone came with the N975U1 unlocked ROM installed on the phone and there is no carrier apps or Consumer Cellular identification anywhere. The only reason I know it's Consumer Cellular is because of a message that popped up for something, can't recall what now.
Anyway, the phone acts just like an unlocked model. Put in various sim cards and the phone reboots through the blue recovery screen to update carrier software for the sim you are using. APN settings are available and can be edited. Everything is just like an unlocked model.
Except, it connects to the network for a couple minutes or so and then stops working. It acts like the Verizon versions do before they are unlocked by Verizon. Except the Verizon versions give you a little pop up stating the phone can't be used on another network. This model has no message.
I am guessing that they are locked using the same mechanism that Verizon uses for locking their devices now except they just are not showing anything to let you know.
Is anybody aware of exactly how this is done and any third party who can unlock it? I have tried a couple different unlocked ROM s as well as an AT&T and Verizon just to see what happens. Same problem.
Thanks
Have a link from the target site to the phone you bought?
I have a feeling that the phone is not actually unlocked or it may not be as what it appears exactly. You can run the IMEI number using swappa and see if the phone is indeed an U1 variant or just the normal carrier N975U.
It maybe possible (not sure how exactly) that your using an international variant that was flashed and configured to look like a N975U1. For example the phone listed here is an international variant that is compatible with US LTE, but I have some serious doubts with how compatible it really is. From past experiences with a local store that sells unlocked Note 10+ units for Net10, I discovered they are not actually US models and are really international models. They were flashed and configured in a weird way (best I can describe it) that it would work for the most part, work with Net10, but it would not work with the other providers here locally. It would at first appear to work but then fail all together.. It wasn't until I started digging into the IMEI number and what it belonged too that I discovered the truth of what the model actually is, and I then promptly returned the phone to the store I bought it from.
If the phone is just network locked and a genuine N975U1 model it would just seem that you only have to use the phone with the service for a certain period of time before they will unlock it. Consumer Cellular would be the best place to go to get (and ask about getting) the phone unlocked.

I resell used phones and specifically phones from Consumer Cellular. All the previous Samsung models used to come unlocked, but about the time the S10 was released, all their Samsung phones came with this unusual lock. I've tried working with countless unlockers and no one has been able to remove it. Once it connects to the internet, it downloads some google update and the phone loses voice/data service. I've wondered how they do this too. A few other models I have that have the same lock are the A10e A20 J7 S10/+ S20/+ Note 10/+. Really really frustrating as I've been searching for a long time now. If anyone knows anything, please let me know. I have hundreds of these that need to be unlocked. Also to clarify, yes they are all the U1 factory unlocked models.
Edit: Apparently when a carrier locked device is flashed to U1 firmware BEFORE unlocking, there is no software prompt to unlock the device. It probably was a carrier locked N975U originally. Maybe on Consumer Cellular firmware, there would be a prompt to unlock it?
These are the guys but they only do commercial work. I am pretty sure they never fail unlock.

These are not the U versions. I've sold CC phones for years and they are and have always been U1 models. Not only does it say it in the software, but even on the back glass. They are locking these things with an update somehow.
I'll reach out to swiftunlocks, but I would put a big bet up that they can't unlock it either. I'm connected with some of the top unlockers in the world as this is my business and no one has any idea. If anyone is reading this and wants a phone to test, I'll even send you one if you think you can unlock it. It's worth a lot of money to me to find a solution. The worst part is that these phones are all paid off and eligible to unlock through the carrier, but since "I'm not the original owner" they won't help me.

Will international version still work when AT&T drops 3G in Feb. 2022?

Will international version still work when AT&T drops 3G in Feb. 2022?
Yes. The WWE version supports LTE. All M8 versions support it afaik
I'm struggling with this. Tried researching it. I know the M8's all have LTE capabilities...the problem is AT&T in the US doesn't cover the same bands or frequencies to support 4G LTE that they do in Europe. So my international version doesn't get LTE. The most I get is HSPA+. I also couldn't find any info on HD Voice which I'm guessing is the same thing as VoLTE or LTE. Which is what is going to be required in order for the phone to work in any fashion on the AT&T network. Or any network for that matter when they decide to drop 3G. I know for a FACT that the US version of the M8 is on the list of phones that WILL work when they make the change. It shows the M8 on the list but it doesn't distinguish between domestic or international versions.

What does it say in your bootloader menu?
Locked or unlocked?
Security on or off?
MID/Modelid?
CID?
You may be able to flash the latest AT&T RUU to get AT&T firmware on your phone.
I can tell you with that information, and give you a link to the RUU and instructions on how to flash it.
I've never accessed the boot loader menu. Never had a reason to. Thought about flashing phones before but didn't want to risk bricking it. And never really needed to change stock version for my needs.
That being said I imagine it's locked with security on. The numbers you're asking for should be standard for international version so I don't think they are relevant. I have a prepaid account through AT&T for at least 10 years. Just been flipping sim card to newer unlocked phones. Got this through Amazon. Previously had US version but after time had battery issues. But I already have access to the AT&T network. And it wouldn't matter if I switched networks. None of the US companies use the bands and frequencies that Europe does for LTE.
. My understanding of it from my research is that it's not firmware that decides that but the hardware and antenna capabilities. The phone literally won't look for those bands or frequencies. At least that's my understanding.
. Thanks for your help though. Ultimately I'm probably going to have to get a new phone. Which sucks because I love this phone. Will miss how great it sounds. Best phone I've ever had. I guess I could just turn it into a music player.

You bought it second hand? It might be S-Off. Bootloader might be locked, but with S-Off (security off) it shouldn't matter.
As far as firmware not deciding the bands, that's not entirely true. Changing the MID to AT&T's and changing the CID to either that or SuperCID would fix it. That would be a part of flashing the RUU. You'll need the AT&T or SuperCID to flash it in the first place, but the MID changes after the RUU flash iirc.
As far as getting S-Off, you can get that for $25. If you want that I can walk you through everything. I don't mind giving FULL instructions although I try to let users do a little searching of their own.
Feel free to PM me if you want to try. Flashing the RUU itself is super easy. Changing CID/MID will take you using fastboot commands from your PC
Thanks. I'll take that into consideration. I appreciate your help. I'll let you know if I'm up for that challenge...lol. I'm running on marshmallow right now. And as such am unable to access certain apps through the Play store. It's probably a good idea to upgrade anyway. I know there are flashes for that too...just makes more sense to upgrade. The phone is 7 years old.

Yep. 7yrs ago one of the best phones came out. I loved my M8. It's bricked now though. The screen got screwed and charging was taking forever and I tried taking it apart to fix it and I failed. lol. Doing hardware repairs isn't in my nature. No patience for that. Too small and fragile. But I still use my HTC 10 during weekdays for an mp3 player at work
Yup...Boomsound! Can't beat it. Otherwise I wouldn't have this dilemma in the first place. Thought about changing my old battery but realized how complicated it was and no guarantee it would work. And paying to get it fixed...may as well apply those funds to a new phone. Expensive! Tried to get the HTC 10 new. Wound up with the international version (Amazon...lol)with problems from the start. Had to return it before I could even hear how good it sounded. I wanted to cry. Now I'm stuck trying to find high quality sound on a reasonably priced phone that still has the damn headphone jack. Ugh.

Hey xunholyx,
I was thinking about checking out the pixels. I heard they have decent sound. I'm going to try and get my US version M8 battery replaced for $75 and hope that's the only problem with it. On top of looking for a new phone. Just can't seem to let it go...lol. Should have done this a year ago. It will give me more time and ultimately be a music player for my car.
But I'm really contacting you about the international version. I found something and would like your opinion. It's about changing the bands.
You'll need to watch it on YouTube or rather read the description or instructions the video gives below it. The video is hard to follow. And I don't know if I need special software to do it this way.
