Would like to know the difference in these methods.. Is adb different with commands? Been reading and it's confusing. Compared to just fastboot flash recovery. Img. Can I still do that after unlock?

Since all over Internet it says that KDZ cannot be decrypted, how are made FASBOOT roms with KDZ extension?
And what is difference between stock and fastboot roms?
As I can see only thing is ability to flash recovery image, for making backup /restore of roms "on the fly"
there are ways to extract kdz files
read this thread

the only difference is that you can use fastboot commands on your phone to flash new roms and recoveries, and lose your warrenty
But it looks like that when you first time flash with fastboot , you can only flash others roms with fastfoot. Normal KDZ wont work on phone, stucked after blue LG animation.
I've seen that this is possible on several phones but it seems that the way of doing it is not very consistent.
So I was wondering if this is possible for the Note 3 and if so how. Also if there is the risk of hard bricking the device by trying this.
I read several times that you could flash boot logos with the fastboot command
Code:
fastboot flash splash splash1.img
or
Code:
fastboot flash logo logo.img
, though I can't even access the bootloader as it seems.
Doing
Code:
adb reboot-bootloader

Yes, the boot splash is in the bootloader and yes, there's a definite and high risk of a hard brick trying to do this. The Samdung bootloader isn't the most friendly when it comes to modification.
I see. Thanks for the heads up, I guess its not worth the risk in that case.
I wonder if anyone managed to do this successfully over the years. Happy the Note 3 is still capable of running one of the latest ROMs.
So since the days of the Nexus I have been using fastboot commans and for some reason no matter what I try all commans fail on the V20.
I am trying to "fastboot erase boot", "Fastboot format system" and so fourth and they all fail. does anyone know why?
YES, It shows the devices connected through fastboot devices, just the commands fail...
Anyone?
I believe the fastboot flashing commands are only available on the unlocked US996 variant.
unlocked？
Yep, you either need an unlocked US996 (as in went to LG's site and got the bin file and did an OEM UNLOCK), or you need to have rooted some other variant (which uses a debug US996 bootloader as part of rooting).
All the others either don't have fastboot at ALL, or if they do have fastboot, the important commands are disabled -- none are usable.

Hi,
I have an LG G6 and I want to put LineageOS on it. The problem is that the custom rom is only available for H870 international version, and not the H872 that I have. LG has an official unlock for the bootloader for the H870 version and I believe one more, but not for the one I have. But of course, I don't need an official unlock thing I can just do it myself, right? But after unlocking, I can't seem to flash any recovery on it because apparently, the 'fastboot' commands have been removed. So no using 'fastboot flash recovery recovery.img' type of command etc. So regarding this, I have three questions:
1) Is it in any way possible to recover the 'fastboot' commands?
2) If not, can I flash a recovery via another method?
3) If I successfully flash a recovery, can I flash the H870 ROM, considering I have a H872?
Thanks for the help!

as far as I know, you can't recover the 'fastboot' commands, but there is a way of rooting your h872 https://forum.xda-developers.com/tmobile-g6/how-to/root-h872-to-including-11g-t3775518 and no you can't flash an H870 international version on an h872 it will brick your phone

Thank you!
Since I bought the Moto G5 I always used platform tools (ADB + Fastboot) version r27.
Two weeks ago I updated to the latest version (r28) and had no problems using ADB, but when I first used Fastboot I was unfortunate to get the following error before every flash operation:
Code:
(bootloader)is-logical:not found
And the flash process apparently went on normally, but it did not, it just bricked my phone.
I googled for the error and found out several Motorola users were having the same issue with other devices too (Moto X2, Moto G5 Plus and I found one other Cedric user with the same problem).
After trying several firmwares with no success I realized the problem was with Fastboot, so I tried both Fastboot r26 and r27 and both flashed my phone normally, but again on r28 I had the issue above, so I warn you all to stay away from Fastboot r28.
Of course it only soft bricked my phone, but if I were relocking my bootloader or flashing a newer firmware using Fastboot r28, I'd hard brick my phone for sure, since that's what to be expected from a failed attempt to flash gpt.bin or bootloader.img
I've been using fastboot v28 with no issues. I used it flash my G5 from Nougat to Oreo a month or so ago, used it to unlock my bootloader, flash TWRP, and flash a custom bootlogo. I do get those "(bootloader)is-logical:not found" messages, but I think it has to do with fastboot looking for the partition structure used on native-Oreo devices for Treble, but I'm not sure. Hasn't been an issue for me though. (FWIW, I'm on Linux)

interesting. I haven't tried this on linux though.

Same for me here using Linux. Still able to flash without issues at all.
