Can we clarify "Bootstack" and what's safe to flash and not?

[qwahchees]

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!
