[Q] What's the cutoff point for ROMs to unlock the SIM? - Sprint LG G5 Questions & Answers

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?

[Q] Help with unlock

To state clearly at first. The new phone in question was not rooted when I purchased it, but I did root it. So the phone is rooted but not unlocked. I thought I should also add that I'm in Atlantic Canada.
As usual, I always seem to have an issue that I look and can never seem to find the answer. This leaves me asking a question that I'm hoping there isn't already an answer to because I know people hate that.
So here goes. I have 2 SGH-989D phones. One I got new 18 months to 24 months ago with my re-negotiated Telus contract. I got the second one "barely used" a couple of months ago and I'm pretty sure it was a Bell pay as you go phone as this is what the person told me. He said all of the phones they get are always Bell. He would have no reason to not be truthful especially since I had a Telus and he knew I would need to unlock it I purchased it because my existing phone was acting up and also the screen was pretty severely cracked.
What I found odd is that when I put the Telus SIM card in the phone, I didn't get any message that the phone was locked. I was immediately able to dial a number and the call went through. I could also send and receive txt's. The phone also says Telus at the bottom of the screen. What is problematic however is that 4g won't work. When go into the new phone under network mode info this appears "GSM/WCDMA(Auto Mode)" But when I look at my original phones network mode I get "GSM/HSPA(Auto Mode)" So, I'm thinking this is probably quite obviously the reason that 4g isn't working and I have no data available unless I connect to wifi. This won't do.
So, where do I go from here? I'm thinking i need to unlock the phone in order to do something about this probably? Or is there something else I can do to pick up the HSPA instead of WCDMA? I'm so irritated by this. It feels like it should be a simple fix since both of these phones are SGH-989d's but maybe it's not. Lastly, and I don't think this makes much of a difference. My old phone is 4.0.3 version and my newer one is 4.1.2.
Thanks and I'm hoping someone knows what or if I can do anything or if I should just give up. I really hate giving up so I'm hoping it's not the latter of the two options.
Moved to Q and A, and, please do not bump within the same 24 hour period.

The phone is unlocked or you wouldn't of been able to make calls etc with your sim.
My guess as to the problem is that your Bell phone is not a SGH-T989D, it's actually a SGH-i757M or GT-I9100M, they are called Samsung Galaxy S2's but there are a few models of the S2 out there. To verify your model either go to Settings > About phone and check Model number, or pull battery and look under it for the model number. To my knowledge, Bell has never sold the SGH-T989D model of the S2.

Thanks for your reply Almite. Unfortunately the phone is the SGH-T989D.. I know it's a weird problem I've got here.
I used to play around with satellites back in the day. One of the things we used to do with the boxes was to jtag the box, erase the memory from the primary chip and then flash it with a different STB's info. This would enable us to do some wonderful things.
Rooting and then unlocking seems like a similar process however I just don't want to flash the phone with something that is going to brick it. I guess I'm going to need to do something. This phone is no good to me this way. If I brick it, I brick it. What I would like from someone in the community would be to direct me to the easiest process to flash my phone with a telus ROM.
I have read A LOT and there are many opinions out there, but I'm thinking that there is probably a consensus on what is the best and easiest way.
Update
I have successfully installed Jedi Mind Trick using TWRP as it appeared to be the best stable one out there. Used Darksides superwipe and then installed JMT. Still have issue of GSM/HSPA on original phone vs GSM/WCMDA on the phone that now has JMT installed on. I must say, I'm pretty impressed with how easily it installed and the ROM itself however sadly it did not help my conundrum.
I'm thinking that there is probably a developer here up for a challenge that could probably assist me with my problem. I really would like to be able to pick up 4g on this phone, or It's pretty much useless to me. What I need to figure out is how I can change this phone to recognize the HSPA network instead of the WCMDA network as GSM does not appear to be relative to data. Not with Telus anyway it would seem.
Maybe this isn't even possible because it's hard coded into the phone or something. Anyone have any ideas?
Last update unless anyone has any ideas

Spent almost an hour on phone with Telus tech support. he explained that WCMDA should work fine as that and HSPA are essentially the same thing. Went through several settings changes and edits with him. In the end, he was stumped. The changes we made should have worked but did not. Therefore I supposed I have no choice but to give up. Guess I'll give the phone to my daughter as i don't want her to go online without wifi anyway.
Same issue
My wife recently cracked the screen on her Rugby Pro so I picked up a slightly used Koodo T989D and plugged in the SIM card. I had the same thing happen. Phone booted, made calls, all seemed well. The next day she realized she had no data connection. I rooted the phone, flashed Telus radio, tried different ROMs, even purchased the unlock code for it hoping for a fix. I can't seem to find anything that will allow this phone data connection of any type other than Wi-Fi. I would really appreciate any ideas or information that anyone has on this topic as I'm running out of ideas and buying another replacement isn't an option.

So I hunted and finally answered this question we both had. Go to Settings:Wireless and Networks:Mobile Networks:Access Point Names.
Since my phone was a Koodo phone it lists Koodo SP. Click the menu button then New APN. Name it whatever you want. I called it Telus. APN is sp.telus.com. Scroll down to MMSC and type http: // aliasredirect. net/proxy/mmsc (without the spaces. They won't let me post a 'link'). Under MMSC proxy type 74.49.0.18. MMS port is 80. MCC is 302. MNC is 220. APN type should be Internet + mms. Click the menu button and save. Click the circle behind your newly created APN and wait. In under 30 seconds I had 4G connection.
Hope this helps you.

SIM Unlock/Root Questions

Firstly, I'll say I'm new to XDA so thanks to all those who offer people like me somewhere to turn to. So, a little back-story, I recently got the root itch after my last ATT upgrade and it would seem it couldn't have come at a worse. For I had just recieved my ATT Galaxy s6 Edge Plus two days prior to being introduced to this site. Needless to say, I put too much effort in finding other devices essentially to "play" (root, flash, etc..) then I should. Which brings me to this...I came across this Sprint HTC 10 still with the plastic on it for a price I couldn't refuse. While trying to go about Unlocking the SIM I've encountered two issues: one being I paid to get an unlock code (actually double due to "high level of security") which ends up saying unlocked from network in a pop up but when I reboot with different carrier SIM, it still says SIMlock Enabled. So, Secondly, I figured try my chances calling Sprint even though I didn't have any of the sellers information. Only to find out, according to her, that phones aren't even elligible to be SIM Unlocked unless they have been active with the carrier for atleast 50 days. I would reallly appreciate if someone could shed light on this and let me know, since I bought it out the box and don't have Sprint, did I just buy an expensive paperweight? Also, if anyone could point in the direction of an effective SIM unlock method, it would be appreciated. And lastly, would rooting it make it easier or expand my options of SIM Unlocking? Thanks for any input.
I haven't tried sim-unlocking this phone but I usually get unlock codes from reputable sellers on eBay. If the code you received doesn't work, I would ask for my money back or ask the seller to help me troubleshoot the issue.
The source seemed to be a reputable and were extremely professional, (HTCunlockingservice.com), and said they got the code straight from Sprint server. I just don't understand why the code won't work. Any knowledge of how factual the service reps statement that if it hasnt been active for 50 days, it cant be unlocked?

In the interest of learning

Years ago, I had a Note 3, and a few China brand tablets. I learned to root them. For the tablets, I was interested in learning how to make them the most compatible for Deaf - understand this was years and years ago. (My parents are Deaf). So I have some understanding - but it's been awhile.
I've been buying a few used android phones in the interest of having loaners and was toying with the idea of repairing phones as a hobby/pin money kinda thing. I'm a veteran and now living on my disability retirement. I've been working in technology - most notably repairing PCs - software and hardware but I've had a few years here and there, networks, databases, security, etc. My resume is wide but shallow.
One of the phones I bought was a Verizon Moto G6Play (obviously I'm here). And I've come to the conclusion I'm an idiot for not researching it closer. My current provider is Verizon and I just naively thought if I put my daughter's verizon sim in it - it would work. I paid no attention to the warning on the back of the box about purchasing up to 50.00 of prepaid in order for Verizon to recoup their money invested in the cheap prices offered for the phones. To be honest, I bought this phone off of "shopgoodwill.com" auction for 6.95. I don't have a lot of money invested in and not sure I even know how much it goes for right now. I don't honestly care. When I put the verizon sim in it - at first it showed 1X - I rebooted and was looking at rooting options but had not gotten real far. I also forgot to pay my bill like always - and got online and caught it up. When I did that - it looked like the sim card updated to 4G and texting was working. But I wrongly assumed calling was not working because I had wrongly assumed in the first place it was not dialing out because I thought I let my bill lapse. (I do this all the time. I'm an idiot).
So, long story, short - I called Verizon and asked why my phone was working but hers wasn't - we got into the discussion of prepaid, etc. The help person said, I wasn't going to get around the prepaid prerequisite - but I might get away with 30.00 instead of 50.00. Ok. Fine - I give. My daughter was willing to pay 30.00+ for a new screen for the other Motorola she had wrecked (E3). I was just trying to get her out of my hair. She is very OCD/Annoying while at the same time always breaking her phones. I told her the skinny on the phone. I told her to take it to Verizon store - tell them you want to go pre-paid cheapest plan - 30.00 and bring it back home. I removed the TWRP and Terminal Emu from the phone and she took it there with her instructions - but somehow muffed it all up. The salesperson claimed it was already activated to our account. In retrospect, I thought I had seen the G6 Play as the model for her phone line. But I told her that was not possible since it didn't work. Right? So a manager came over - and told her the phone was phu(ked I do believe she told my daughter "bricked" and that she'd have to buy a new one. Needless to say I told my daughter to get out of there - they were not interested in helping - they just wanted her to buy a phone. Prior to sending her to the store - I had run through the steps here or where-ever I was - and found the codes needed to determine if I could unlock this phone and was told, nope, nope, nope.
I reset the phone completely from the Fastboot Flash Mode (sorry, if I'm not using the right term - I always want to call it bios, ). As far as I know, it was successful...
So here is the thing. Looks like I'm stuck with it - and I'd like to try my hardest to crack it anyway. I don't care if I brick it or not. I'm looking at practice here. Do I absolutely need the unlock code to get started? Can I just jump over that step and flash a new OS to the phone? Bearing in mind that I might brick it?
Thanks,
Wynne

Is this phone currently in a running state? If so, do you have twrp and root? I may be able to help you. I know it's G6 play but do you know which model it is? mine is XT1922-7 for example

He isn't able to unlock the bootloader and wants to know whether he could unlock it without the unlock code.
@impy2101 You'll need that code to unlock the bootloader and being able to do modifications. Every attempt to flash another firmware while bootloader is locked will fail or could lead to a hard brick.
Did you follow the steps from Moto's website to unlock it?

The short and long answer to that is no. The process is relatively straight forward though.

Yes, brand spanking new - It's just that I bought it from GoodWill so there is no returning it. And it's all good. I only paid a few bucks for it. It's an XT-1922-2. Thanks. I found the, um, erm, (sorry, old lady stuff going on) the OS MOD for it? jeterxxxblahblah and downloaded it - just not sure how I would get it loaded up if I cannot unlock it, etc.
I need to understand a little better some of the things that "we" do to the phones. For example - when unlocking the BootLoader - who locks it in the first place? What does unlocking the bootloader give us access to vs. what does root give us access to? I ask because I also have a Moto E6 and I managed to get past the pre-paid requirement and have unlocked it, rooted it (sorta - kinda weird work around where I have to boot it "recovery mode" if I want to use root - otherwise not. And I've discovered I still need another step to get rid of the provider USCellular so I can stick a VZW Sim in it. (Not asking for an answer here - just saying that I can follow instructions and understand to a certain degree but would like more indepth detail on what it is I'm doing. I even went so far as to look for the OSI model equivalent for Android - I found it - but it wasn't quite as satisfying as the one for PC - I'm still a bit puzzled.)

Yes, I followed the Moto website to unlock it - it was considered unlockable. I'm well aware it could lead to a hard brick. Apparently, when I put my Verizon sim in - I did something to it already that effed it up. According to them. I made the dumb assumption that if I had Verizon as my carrier I could use a prepaid phone as a backup device. And I'm sure I've done it before when I was with AT&T. So it may be I already made it unusable. I would like to go from knows enough to be dangerous - to really qualified. There are big chunks of information that I need to understand in order to put it all together - sometimes breaking something is a good way to learn - in fact, it's often the best way, I've discovered.

So in terms of unlocking we have two different ideas here: 1. unlocking the bootloader so you can change to a custom version of android or obtain root access and 2. Unlocking the device's sim slot to use it with another network provider. This is usually done by asking the provider to unlock it, the pre requisite is that the phone or tablet must be paid off or good standing for at least one year. This is the policy of boost, sprint, virgin etc Verizon may be different. While some third parties may be able to accomplish this, it can be risky to the consumer and may even need to be done remotely. What exactly are you hoping to do? I'd be happy to help you if I can

I'm more hoping to unlock the device's sim slot - ironically - this is a Verizon pre-paid and I want to use it with Verizon - my current carrier. I bought the phone in hopes of replacing a phone that quit working on my daughter.
I would like to understand the difference though - I've been fooling around with a Moto E6 and have unlocked the Bootloader - I did go to Motorola's site to get the key based on issuing a fastboot oem get_unlock_data command from the cmd prompt screen. Got the mile long number sent it in and got a key and ran the command to unlock it. I think because it's a newer model - E6 - it's a bit of a weird hinky thing to root it. It can only be done by booting the phone in "Recovery Mode" - I can add all kinda Magisk modules, etc...I can even blow up the phone and reinstall it.
But I can see that the Network is still Consumer Cellular. I'm really getting confused about all of this, lots of terminology without explainations, etc...so in order to teach myself effectively I'm looking at schematics of phones and building my own diagram - sorta like the OSI model for a PC - showing where the bootloader resides, the os/recovery resides, and so on, right? After seeing the Consumer Cellular is still the provider - I searched again and found a page that says I need an unlock code - and as you also said - I've run into this advice a few times - that the owner must fulfill the prerequisite contract time. I had tried arguing with Verizon that I already spent more than 50.00 by being their customer for 4 years and letting them charge me for an entire year for international service despite me telling them to turn it off 4 or 5 times (no sympathy from them...)
I'm extremely confused - where is the "code" that locks the sim to a carrier? Obviously, its not in the bootloader. Clearly, it's not part of the rooting process - which I understand is just granting permission to root directories. Is this code the same code that locks out a pre-paid from a regular sim?

I'm more hoping to unlock the device's sim slot - ironically - this is a Verizon pre-paid and I want to use it with Verizon - my current carrier. I bought the phone in hopes of replacing a phone that quit working on my daughter.
I would like to understand the difference though - I've been fooling around with a Moto E6 and have unlocked the Bootloader - I did go to Motorola's site to get the key based on issuing a fastboot oem get_unlock_data command from the cmd prompt screen. Got the mile long number sent it in and got a key and ran the command to unlock it. I think because it's a newer model - E6 - it's a bit of a weird hinky thing to root it. It can only be done by booting the phone in "Recovery Mode" - I can add all kinda Magisk modules, etc...I can even blow up the phone and reinstall it.
But I can see that the Network is still Consumer Cellular. I'm really getting confused about all of this, lots of terminology without explainations, etc...so in order to teach myself effectively I'm looking at schematics of phones and building my own diagram - sorta like the OSI model for a PC - showing where the bootloader resides, the os/recovery resides, and so on, right? After seeing the Consumer Cellular is still the provider - I searched again and found a page that says I need an unlock code - and as you also said - I've run into this advice a few times - that the owner must fulfill the prerequisite contract time. I had tried arguing with Verizon that I already spent more than 50.00 by being their customer for 4 years and letting them charge me for an entire year for international service despite me telling them to turn it off 4 or 5 times (no sympathy from them...)
I'm extremely confused - where is the "code" that locks the sim to a carrier? Obviously, its not in the bootloader. Clearly, it's not part of the rooting process - which I understand is just granting permission to root directories. Is this code the same code that locks out a pre-paid from a regular sim? I'm guessing whatever it is - it's not part of recovery.img at least.

I know what you mean by the code and my best answer would be that the carriers themselves have it. It is not common place for the sim unlock codes to be public because if that was the case, no one would or could be locked into a contract and the carrier companies would lose big time money. There are services to unlock sims but as i mentioned before, I've never tried them. so i cannot say if it is a safe or good idea. I have switched carriers using other ROM's besides stock and using other cdma sims in my phone but i was switching carriers. I had to edit my access point names manually for it to work and root was also needed.

Well, clearly the code is not in the SIM card itself. I had good luck with AT&T prepaid. I think I found a page that indicates I can just call Consumer Cellular for my E6 and hopefully they won't force me into a contract fulfillment requirement first. For the G6, it's Verizon...and I'm thinking I gave up too soon. Verizon owes me a big favor because they kept charging me for International Calls. Granted I didn't call every month and yell at them but it took them a year to take it off my bill - I only checked once every 2 or 3 months. My bill was never the same regardless because of the constant adding and changing - so I missed it (and would forget to check).
That makes sense that the pre-paid "lock" is not public and not located in easy to search spot in the phone. I'm just trying to puzzle out the system. Is it something that would be found in the BootLoader? Unlocking the Bootloader is the first step - so you'd think it might be there. Probably not - because Bootloader's job is to load the boot the operating system. Is the Bootloader and OS on the same chip but with partitions? Or do they have separate chips? I've been studying the innards of an android phone - the various chips and there functions - it looks like two possible chips; either the ROM IC which I believe contains the bootloader and I know contains the OS (or just the kernel?) or the Flash IC which should contain "Software" and IMEI Number of the mobile phone. The others are for functions such as sound, network, tx/rx, power, CPU, etc. So? Is there a separate module (chip/ROM) in the phone specifically for the SIM slot - that the OS accesses at some point in loading? I just have a burning curiosity on where it would be stored. Don't worry, I have no real developer skills and no time to "hack" out the issue I'm having anyway. I just learn better when I understand how all the puzzle pieces fit together - I'm puzzled by this aspect of pre-paids - it must be an entirely separate module (software or firmware) that has been added to the basic OS - but where?.....
It's a matter of terminology.
SIM Lock / Carrier Lock - this determines if you can use different SIMs from other carriers. The setting could be stored in nvram or baseband image. Verizon phones usually automatically sim/carrier unlock after 24 hours on their network.
Bootloader lock/unlock - this allows modification of the partitions/software. Generally, if your bootloader is locked, you can only flash "signed" images. If you brick your phone, you can generally reflash stock roms to fix.
Most phones direct from carriers (Verizon, ATT and TMobile) don't allow bootloader unlock, especially the good deals.
MVNOs like Tracfone(and their subsidies Simple Mobile, Straight Talk, Net10) will sim/carrier unlock after 6 months to a year of paid service. They generally don't officially support bootloader unlock, that's usually through a hack.

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.

Have you tried updating after taking out the SIM card?

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.

Quite A Few Questions About My Rooted LG G7 ThinQ (ULM)

So, I have an LG G7 from a couple of years ago that came with G710ULM11g (BPT). And unless the phone manufacturer itself disables unlocking the bootloader, 99% of the phones my carrier offers are unlocked versions (ive been able to easily root every phone from them for years except for Samsung phones recently, they suck.) But After getting a different phone, I rooted the G7 and flashed it with G710ULM21f (BPT) stock rom. No problems. But i just recently accidentally smashed the LCD screen on my new phone and its unusable at the moment and I cant afford to fix/replace the screen currently. So, I took the SIM out of that phone and put it into the LG G7 and noticed that the antenna bars only displays "1x" next to it. So, I went on a deep dive researching spree the past few weeks to see how I could get the phone receiving 4g/VoLTE like it used to. After hours and hours of research and reading and re-reading xda threads, reddits, posts on other android forums, blogs, and watching countless videos, I still haven't figured it out. I tried changing the APN settings, changing LTE Field test settings in the service menu, adding the enabler file in root, and exploring the root files with ADB to no avail. I managed to screw the phone up multiple times to where I couldn't even get 1x though but always figured out how to get it back.
I also came across articles, threads and other posts on the internet from people claiming that once the G7 is rooted that it will no longer be 4g/VoLTE capable ever again. And then I came across 2 or 3 threads claiming that if you crossflash with the correct firmware that you can get 4g/VoLTE back on the phone. And I'm not sure which one to believe. BUT if the crossflashing threads are true then I would like to try it. My problem is that not only have I never crossflashed firmware on any of my phones before, and I have no clue which firmware to crossflash with which but I seriously can't understand some of the steps in the threads that I read. I know HOW to follow instructions and have flashed custom roms on past phones but some of the steps I'm confused on since they're not using terms that I'm typically used into flashing tutorials and I really don't want this phone to get hard bricked. So, if anyone could help me out with which firmware I need to crossflash according to my region while also explaining the steps a little better, I'd appreciate it.
I also came across info stating that some carriers will allow someone's sim to be put into another unlocked phone and it will work fine. While some other carriers activate their SIMs to be phone/imei specific. Now, I'm not exactly sure which of those my carrier does but I'm leaning towards the idea that they're SIMs can be put into other unlocked phones due to the fact that my G7 is technically working with the SIM as in I still get 1x and I can still send and receive calls and texts but I just can't receive 4g/VoLTE. So, I'm thinking that if its real, the crossflashing idea would be the way to go.
I feel like I'm forgetting to mention something else so if I remember it, I'll be coming back to edit/add to this post. But any help would be greatly appreciated!
Thanks!
