Since H830 has been rooted, I strongly believe the others will get rooted some time down the road.
In light of that, I'd like to ask experience devs or people who know about the G5 this question: what's safe to flash and what isn't?
I've had experience with the Samsung Galaxy Note 4, and flashing TMobile stuff onto Canadian variants worked no problem, would this be the same for the H830/H831?
Seeing as these variants are similar in model # and a few discussions about how rooting the H831 would stem from the H830, is it safe to flash vice-versa?
Thanks XDA!
I'd say, you shouldn't flash anything. These models are not just different in model number, but radios used, and possibly other small things too. Just because the model name is similar, it does not mean it's safe to go around flashing other variants' stock firmware.
H830 and H831 are as different as night n day when it comes to unlock, root etc.
you CANNOT flash H830 bootloader/modem on any other G5 model, period. insta-brick. and not the kind u fix with flashing stock firmware back. H831 root/unlock will never stem from H830.. so let's end all of those discussions right now. H831 is in same ballpark as the locked AT&T, Verizon and Sprint models.
the 2 partitions that you could flash and it wouldnt brick you would be boot and system.. but those probably wouldnt let u boot into android.. but you wouldnt be bricked.. could recover with KDZ.
G5 users should only flash the software for their exact model.
there are a few exceptions... H850 variants .. H850N or w/e for example could flash H850 kdz and it would not brick them.. but it also wouldnt help them with unlock since the H850 unlocks are based on IMEI in LG's database.. not the software you flash. Another exception would also be for the intl users.. someone with a German H850 could flash another countries H850 sw as the only differences might be carrier settings and languages settings.

So it's safe to flash H860 kdz on my H860N device? Not really planning to do that as I really want to play safe with my phone, but just asking

not sure if dual sim would stop working.. but it wouldnt brick you. as of today anyway.. a future update could change the qfuse version or something.. and flashing something with a lower version would cause issues.
The only people who should be considering flashing another phone's kdz are those with H850/H860 carrier versions who want something unbranded. for example.. an H850 vodafone phone user may want to flash an H850 EU OPEN kdz.
or
Bootloader unlocked H830 users could adapt a system.img (only the system img.. not a full rom.. not a kdz.. etc) to work on their phones and flash the system.img with twrp.
Thanks for the replies, that clears things up relatively simply.
The thing is, carrier H850 and EU Open H850 are NOT different SKUs. An H831 and an H830 are different SKUs and quite different HW.

As it seems so. Like I said, the Note series was a bit different, almost identical hardware with two different SKUs, but I guess the G5 is done differently.
Praying for root soon! My eyes are bleeding from night-time blue light!
I need Band 66 (LTE) with my Canadian provider (Freedom Mobile). Both the H918 (T-Mobile) and the H915 (Freedom Mobile) have Band 66. With my new unlocked LG V20 (T-Mobile) version running on my Canadian Freedom Mobile LTE version, all works well, with the exception of no LTE. I have done many searches and come up confused as to which way to do this. Can I use just LG UP and flash the H915 firmware over the H918 and expect all to be well with working LTE on my LG V20? Has LG Flash Tool been replaced with a newer LGUP? I'm just spinning in a forest of confusion here. Any direction would be appreciated. Thx
Wow..... 3 days have passed and no answers to my question. Have I stumped the experts?

It is never recommended to flash a firmware not meant to be for your phone. Chances are that you will brick your phone if you do. Probably that's why no one is answering because it has been said many times in different ways. And almost no one likes to be the guinea pig. Nevertheless, if you do try it with LG UP, let everybody know about your results :good:
The H918 doesn't support as many frequencies as the H910 / H915 (the H910 and H915 are the exact same phone). That could be a limitation of the radio firmware, and if it doesn't soft brick your phone, could be fixed by flashing the H915 KDZ.
Now the good news there is a KDZ for the H918, so, if you soft brick your phone -- viola -- flash the H918 KDZ and you are back to where you are.
Just a heads up though, download mode is *ALMOST* impossible to blow up, but almost is not the same as impossible. I personally have never managed to destroy download mode on an LG phone (and I have deliberately tried on several older phones - G2, G3, G4, just to see if I could recover if it happened).
However, that isn't to say that it is completely impossible (the dreaded 9008 error). Example for LG G3: https://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359
But, as you can see, even that can be fixed as long as you: 1 - have a KDZ, 2 - are willing to tear apart your phone.
Please post your results if you decide to go through with it

The only LG Phone that I own and remember was The E980 Optimus G Pro “the unbrickable” and thanks to att to ruin a outstanding phone simply not get the promo and the attention of the same sh** of Samsung S4 for this time.
After 2 months passing from my original post, I'm still at the end of a dark tunnel...... and no BAND 66 working on my T-Mobile H918 running on the Canadian carrier........... Freedom Mobile . Has anybody had any success running a TM (H918) on Freedom Mobile and get LTE (Band 66)?
You can't since the kdz for freedom mobile is not out yet

I have been looking at the FCC documents, and I seems H918 is the same hardware as the H910PR.
You can also see there that H910 and H915 are the same, as mentioned above.
I would not try to cross-flash firmware from different phones at least, if I where to do it at all.
Edit: The H918 has a unique oem configured key in the qfprom. Meaning flashing any bootloader not specific to the H918 will hard-brick your phone, at this point that is equivalent to a completely broken and useless phone.
if we can get the KDZ file maybe can get the modem
Any luck on this in the past month, or same situation still?
Freedom have had band 66 allowed to be used only on handsets sold by them, probably by white listing IMEIs. Now that they have iPhone, this might change, but my knowledge is limited.
Hello everyone! I need the help of this community to try to overcome a doubt that plagues me.
I am a happy user of a LG V20 from VERIZON, however I am using it in Portugal. The only problem I found was the lack of APN, which I solved with the manual configuration. With regular use, I noticed that this equipment has a great deficit in network capture.
This way I ask for your help here. My equipment being a VERIZON equipment, VS995.
Can I install a ROM from other devices? Namely H990DS, H918, H910, US996, LS997.
If so, what guarantees better network coverage? Which one has the least trash from the operator?
I run the risk of having the phone locked if I change ROM?
Thanks and see you all soon.
I can only tell you that if you flash the H918 firmware, you will brick your phone. The H999DS just won't work. The others .. flash then and try. Make sure what you flash is ARB 0 since the VS995 is still ARB 0, and if what you flash doesn't work, you need to be able to flash the VS995 KDZ back .. can't do that if you have flashed firmware with a higher ARB.

Hello all,
I'm really new to the phone modification scene. I tinker around with computers mostly. I have an unlocked sprint version of the LG v20, the only problem is I am not receiving data on my new carrier (even with the correct apn added). I'm pretty sure this is a firmware issue. I was wondering if there was a way to flash the us996 or verizon version of the phone to get data to work. I know the sprint version is super locked down. I just didn't know if using a modded version of LGUP and the us996 kdz would brick the phone or not, or if there was a way to flash different firmware on the version I am on.
Thanks and cheers,,

everything is possible, if you do it by yourself

Your firmware has anti-rollback enabled (ARB1), and the US996 and VS995 do not (ARB0), so flashing any KDZ (Sprint does not provide KDZ files at all) will surely brick your phone permanently. You're pretty much stuck with the Sprint firmware you currently have, and the only change possible is taking an official over-the-air update to Oreo, but that could re-lock the phone to Sprint only again.
If you're getting into phone modification, then you'll be much better off with any other LG V20 variant as they are all rootable, unlike the Sprint model with ARB1.

That really sucks, yeah I don't really want to try and hassle with sprint customer support, I got the phone second-hand from my step-brother. So, i'm not sure if they would even unlock it again for me. Thanks for the information. I wasn't sure if there was a way to flash certain parts of the software to possible fix the modem issues or not.
So I picked up this old flagship budget phone and I was having no service at all. I tried resetting the phone, and reconfiguring APN settings, scanning for networks, but nothing worked.
So I did some research, and it turns out I was told I was getting the US996 (factory unlocked) version which is compatible with all carriers. But when I look under the battery, it says LS997 instead. But when I look at the software settings, it says Software Version US99610p. The seller must have flashed the US996 firmware onto an LS997 (Sprint) phone.
So at this point, I'm pretty sure I got scammed, and the sad part is this phone isn't refundable. I thought maybe if I could somehow get this phone off the US996 firmware and back to the LS997 firmware it originally came with, I'd have no problems. My carrier is Sprint as well.
But the sad part is, there's no LS997 KDZ's which I could just flash, since Sprint, unlike other carriers, does not release KDZ's.
So at this point, what are my options? Any help will be greatly appreciated.
Not sure if this is of much help, but if I were you I would unlock the bootloader and just flash a custom rom.

I thought of that, but should I use the LS997 method or the US996 method to unlock?
Honestly Im not too sure since I have a H918 and none of those, Take my info with a grain of salt as I might be wrong, I think that the firmware update partition is not a part of the OS so you may be able to get away using the LS997 method?
