H815 Questions

Was thinking on buying the H815. Wanted to know a few things before I do since I have till Monday to research it..
1. I hear there is the US and a International version? What's the difference? Which is 'better'?
2. I take it that the H815T and so forth are versions for other countries?
3a.. From what I've learned each carrier has their own version of the G4, but it seems that a lot of sellers selling the H815 have bought them from AT&T, Verizon, etc. How does this work when the VS986 is the Verizon version, etc.
3b. It seems that these H815 versions have bloat even though they are carrier unlocked?
4. Do all H815 phones have the boot loader unlocked or just the International version or?
5. I also heard someone say that I will lose out on DRM with the International version? what exactly will I miss out on?
6. I heard that the International version gives better performance, faster updates, etc. Is this correct, what other benefits are there? Do I lose anything from the International version?
7. Regular G4 question: I hear a lot of the phones do CDMA, some only do GSM, with the options to change the Network mode and APN settings, it seems that the G4 would work with any US carrier, am I wrong? With those settings that can be changed it seems so. I know some versions do certain bands and such but as long as your G4 does the bands your carrier does, all should be good, yes?
8. Additional question: How does one check to see if the boot loader is unlocked?
Thanks!

I'm surprised no one knows these answers. Hmm..

Flashing LG H815(International Version) rom onto LG H812 (Bell Canada) hardware

Hi all,
I am going on a long trip to the UK and Middle East, and want to take my LG G4 with me and use foreign service providers. I am planning on flashing the H815T (Similar to H815 International Version but supports more bands) KDZ file onto my existing LG H812 (Bell Canada) hardware, so I can have support for those frequency bands in the UK and Middle East.
According to my understanding, the H815T rom is compatible with the H812 hardware, as both the Bell Canada and International Versions have the same underlying hardware, but I would gladly appreciate if someone can confirm this. I have attached the phone details below.
Thanks and all the best!

The risk is not worth it ...

The risk is not worth it ... It is a lot cheaper to carrier unlock your phone so that you can put any foreign service provider's SIM card in rather than having to buy a new phone when you (hard?) brick it, i.e. ~ $20.00 vs $700.00 (or ~$150.00 on ebay for a used one).
But if you insist ... carry on.

I have done so previously with Samsung Galaxy S4 (all had different model numbers), I used to flash different carriers firmware regularly, as I travel quite often. Just wondering whether the same is true for LG.
Thanks!

Unfortunately ...

Unfortunately ... because you cannot unlock the H812's bootloader (at this point in time, any way), you cannot safely flash different firmware in the same way you did with your Samsung. Unlocking your carrier so you can replace your SIM card with foreign providers and if you wish, installing steadfasterX's TWRP-in-FisH to have a custom recovery is about it for now. If and when steadfasterX completes his efidroid port to LG G4 locked devices (he's working on it now for unlocked devices), then you may be able to install different firmwares.
All of us H812 owners as well as many others are in the same boat.
Safe travels,
S.

For Xiaomi yes: they unlocked the bands, still couldn't get running. I can't tell for LG, maybe every LG uses same antenna or they using different antennas. Check out, if your phone requires special antenna, then you now for sure. Just check that out, before you spend your time on this.

So if they are hardware based, then howcome when you unlock the phone, it suddenly supports all the bands? Also by antenna, do you mean the GSM transmitter and receiver?

Octopus Box/Dev Patched LGUP Thoughts

ChazzMatt said:
You mean like an Octopus box?
I mentioned it in this post:
https://forum.xda-developers.com/showpost.php?p=76325684&postcount=42
Just remember that post was written back in April 2018, when we were still figuring out the Frankenstein method. But these "boxes" were allowing online sellers and online unlockers to convert V30 phones to OTHER variants seemingly willy nilly. We found LS998 V30+ which had been converted to Canadian H933 V30+. Canada H933 doesn't officially have a V30+! Just like there's no VS996 V30+! But you can make one.
Once we figured out the PC based Frankenstein system with dev patched LGUP, then we could do almost the same thing ourselves. Since then, I even bought two mint LS998 V30+ myself and converted them to US998 V30+.
But when I made that post I expressed severe reservations about buying LS998 in the first place -- since they were SIM card locked to Sprint. Like I said, we didn't know everything we know now, and I've changed my mind on the topic.
Whether one of these boxes could help you or not. My understanding is it basically does what dev patched LGUP does. Maybe it does it more automatically and there's less chance for error? I don't know.

So, ChazzMatt, you started something... I just thought I'd share these details with you guys in hopes that it gets the ball rolling on something big.
But these "boxes" were allowing online sellers and online unlockers to convert V30 phones to OTHER variants seemingly willy nilly.

I remember these boxes... My first experience with them was back in the days when Nokia was a huge name in phones. I had a Bell locked Nokia RM-579, which was the NA market 2730. Used BB5 SL3 security. Made it almost impossible to remove the USIM lock too... But from playing around with some of the software, uncovering factory service manuals, and playing with Nokia Diego, I found out that (at least, the Nokia factory boxes) those boxes interface with the phone in ways i only dream of. For all of Nokia's phones, they make special jig's that connect with contacts found on the PCB, typically under the SIM/USIM tray. To use them, you also need the special power adapter tool as well since the battery typically needs to be removed. I would guess that these boxes converted a standard serial port or USB port from serial signaling, to something similar (I think) to TTL or Transisitor-Transistor logic. Those boxes would allow you to make that phone your... you know what. You could repair any issues that had anything to do with software... Somehow obliterated the firmware? Fixed! Accidently flashed the wrong baseband and bricked your modem? No Problem! Need to reprogram baseband parameters? Piece of cake!
With the ushering in of the non removable battery, I assumed they'd go by the wayside... But apparently not... How they interface with the phone, I can only imagine... For TTL to work, you only need three pins... Your Tx, Rx and Ground. You could have the phone wired so that pin 4 of your micro USB port is hooked up to the Rx on the serial port of the CPU, then use pin 3 as your Tx and 5 is already your ground... Just saying. With USB-C there are a multitude of pins to choose from, and you only need three. Apparently they're doing something like this with those boxes because of the Franken-phones that have been reported... Which makes me wonder how those boxes worked...
I personally assume that those boxes also rewrite the security keys that tell the phone the software is valid. And at least in my mind, so long as the V30 you're flashing has the same hardware as another in terms of baseband and radio frequency support, then theoretically speaking you can reflash any portion, such as the modem firmware and paramaters as well as the system partition, you could theoretically speaking make a Canadian V30+ variant, or any other variant out there.
Now, the other thought I had comes from my days with HTC.... Ingenious people really... My last phone prior to the V30 was an HTC 10. Quick rundown on how it worked... HTC allowed unlocking the bootloader on all their phones except Verizon ones (for the 10 at least). Using their unlock would allow you to flash unsigned images to the System, User, and Recovery partitions for a custom firmware... This however left S-On, or Security On. The Sunshine team figured out how to set S-Off. This allowed you to flash whatever to wherever and change whatever you wanted. This meant you could change your general North American variant to a European or Asian variant and then back again if you so desired. You would change the model ID, then run the HTC firmware recovery executible on your PC, or boot into download mode on your phone with the firmware on your SD card, and presto, your phone would become that model as though it was that from day one. No signal issues, no battery drain issues, perfect software operation. I can vouch for this, as I converted my 2PS6500 (the NA variant), to a 2PS6200 (the EU variant) which worked flawlessly. I then realized I made it a European model and converted back to a North American one but needless to say, there were no problems at all... I don't know why the HTC 10 can be converted between variants with no baseband issues at all... I personally would think that when flashing a North American phone with European firmware it would cause the baseband to crash and cease working at all. That's what it does with all other phones I've accidently done it to...
I hope this helps to spur some of the brilliant minds on this forum to figure out if this is possible with the LG V30, or to help figure out the deeper darker secrets of this phone.

For.anyone wanting to dig further, I'm not familiar with the octobox but this sounds like a JTAG interface.

Some manufacturers basically create one "global" phone with all bands activated, then lock down bands via firmware to create their "regional" or "carrier" models. This is their business model. If they created and sold a "global" model, then you would import the cheapest phone you could find from some developing country and Verizon/AT&T wouldn't make any money on hardware sales.
IF you Google: "unlock Qualcomm LTE bands", you will see a few years ago people figured this out, and started unlocking extra LTE bands which were present originally on their phone but firmware locked down to become a carrier model. You could turn your phone into a "global" phone. Caveat: Using this method, you could not activate bands out of thin air, they had to be there already, and the hardware (like antenna) had to support them. But similar to the the "hidden menu" stuff, you use this method to activate ALL the bands listed and they would work.
Most times you also needed root to do this. Also more recently this doesn't work much any more as OEMs have taken steps to thwart this freedom.
But in the same way, the North American V30/V30+ (except the T-mobile H932, due to different RSA encryption) seem to all be the same phone except for firmware. The carrier unlocked US998 is the closest to a "universal" North American V30 -- but it's missing some Sprint bands (found on the LS998), some minor AT&T bands (found on the H931), and the new T-mobile band 71 (while the H932 has that). I'm sure somewhere in an LG vault, there's a "super" US998 that has ALL those bands. Maybe even a "Master" V30 with every GSM/CDMA/HSPA/LTE band -- but LG won't sell that because it would make the carriers mad.
This is why they put different RSA encryption on different models.

Everyone is talking about the band , I did not understand if there is any benefit to add more band ,Is it an improvement to lte. and Does Korea model v300s need more lte band or this is unnecessary?
Please I just want to know. I am from Algeria and my networks are "Djezzy" and "Mobilis".
the signal is good and lte work great no problem.

Then you probably don't need any additional LTE bands.
Korea variants are hard to mess with. You risk losing the mobile signal, if you convert to another variant.

Difference between models XT1952-1,-2,-4

I know that the XT1952-4 is the unlocked version for CDMA and GSM and technically has all the bands for all the carriers.
I am seeing XT1952-1 & XT1952-2 listed as global/international models but can not find any definitive documentation detailing the differences between the 2.
I am going to be getting one of these for my wife. We use Cricket (AT&T) currently. If we were to switch, it would likely be another AT&T MVNO, but we wouldn't rule out T-Mobile (or their MVNOs). CDMA (Verizon/Sprint) likely wouldn't be considered, so I don't need to get the XT-1952-4 version. I can save about $30 going for the XT1952-1 or XT1952-2. The question is...which one? What are the differences? Single/dual sim? Bands?
Any clarity?
Thanks!

You will definitely want to go with the US model (XT1952-4), and not any of the international models. The US model has the necessary compatibility for US carriers, while the international models will not have those bands (for example, the US model supports T-Mobile's new 600MHz signal, which is not present on the international models). Additionally, international models will not have many carrier-specific features, such as VoLTE support and RCS, that you will only get with the US model.

Thanks for the advice!

I've come across am XT1952-4 for a good price, however, it is advertised for Sprint only. How could this be if it is truly an XT1952-4? False ad or misinformed seller???

That is correct. I own a Boost Mobile (Sprint subsidiary) xt1952-4 which is locked to the Sprint network out of the box. The Sprint variant xt1952-4 is supported for bootloader unlocking via Motorola's official unlocking portal.

Bootloader unlock is cool. But is it possible to sim unlock for other networks, or are there hoops to jump through?

That's a great question. Traditionally, Sprint doesn't make it simple for its branded devices to gain network/SIM unlocking or full GSM support and operability. They resort to encryption embedded partitions to network lock their devices. For example, the Sprint compatible Moto E (2nd Gen) from 2015 has yet to be exploited for GSM support. But, the Moto E4 (xt1766) was recently exploited for GSM functionality (but only if the device was never upgraded beyond a certain firmware build). On the xt1952-4, I've yet to hear of anybody network unlocking it, but again I have not researched it much.

For anyone that's interested, as of today (12/6/19), eBay and direct from Motorola have the XT1952-4 fully unlocked (all network compatible model) on sale for $129. Don't know how long the sale will last.

The model you want is the XT-1952-4 PAE80008US. The QA section on BH Photo confirms that PAE80008US is the unlocked Retail US model

I'm a little confused

I thought all Snapdragon processor used devices where u.s. version devices.and that all exynos processor devices where international devices.I want to buy a international device Samsung galaxy s20 plus that I can root and flash different roms and mods on too. Which International Version device would you buy if you wanted to place Round 2 mods onto is there any particular one or just any International device. Because all u.s. versions of the s20 plus cannot be rooted and romed correct. Thanks In advance!!!

The International Snapdragon variants have a better SoC however being in Denmark you won't get some Carrier Features the Exynos variants offer, that's the trade off.

I have the Hong Kong variant on T-mobile. Advantages - Snapdragon SoC, no carrier bloatware, close to pure android, dual sims, unlocked bootloader, price ($745 on eBay). Disadvantages - Warranty repair would be difficult, no 5G yet or carrier aggregation. Highly recommend, my S8, S9 and S10, all Hong Kong variants, never had any problems whatsoever.

You should post a guide on how to unlock the bootloader on the US model. To my knowledge no one has been able to achieve this.

Not to me, I typically download large files on my laptop via WiFi then transfer them to my device. I'm a frequent flyer so I watch movies (torrents) which are typically 2GB. Not sure how long that would take to download on my device via T-mobile but it's not significantly faster than WiFi. When mmWave is widely avaliable Carrier Aggregation will be more valuable but right now High-band 5G is comparable to WiFi file transfer speeds. That's a small inconvenience compared to the benefits the device offers.

@varcor did you change the CSC to see if CA works ?
I'm assuming you're on TGY. I'm also in the USA and think changing to BRI might increase ca bands.

No, my CSC is TGY. I live in Mexico but use T-mobile since they offer free calls and data in collaboration with Mexico's largest telcom Telcel. Even when I'm in the US I don't have CA. I haven't gone to T-mobile to ask if they can configure CA but I doubt they can on the SM-G9860 or SM-G9880 regardless of the CSC. I use a laptop with Wifi for large downloads so it's not a priority. I do get Wifi Calling and VoLTE even in Mexico, YMMV depending on your service provider. Also I've read BRI has some issues so I'm not inclined to make the switch.

No, my CSC is TGY. I live in Mexico but use T-mobile since they offer free calls and data in collaboration with Mexico's largest telcom Telcel. Even when I'm in the US I don't have CA. I haven't gone to T-mobile to ask if they can configure CA but I doubt they can on the SM-G9860 or SM-G9880 regardless of the CSC. I use a laptop with Wifi for large downloads so it's not a priority. I do get Wifi Calling and VoLTE even in Mexico, YMMV depending on your service provider. Also I've read BRI has some issues so I'm not inclined to make the switch.

That link is google amped , perhaps you can edit it to make it viewable, thanks.
I was just curious to know if someone had changed their CSC to BRI and if it enabled CA.
I believe the first thing to be gathered is what bands are CA enable on the BRI CSC before even proceeding with anything else.
Also before flashing to attain CA I think one needs to compare tgy and bri CA combos.
Edit. Read that already, mainly non americans discussing attaining 5G on their respective countries.
