Bootloader Version vs ROM Version? - Verizon Galaxy Note 4 Q&A, Help & Troubleshooting

My question is, does it matter what bootloader version you are on for a custom rom?
Far as if I am on MM Rom (Jasmine 6/7), do I need to be on MM bootloader version or LL bootloader for LL Rom? I know I need to be MM bootloader to even be on MM ROM, but do you understand what I am asking? Do I need to be on LL bootloader for LL ROM and MM bootloader for MM ROM?
Can I be on MM bootloader and have LL ROM?
The reason I ask is I am on the MM bootloader and have Jasmine v7 installed and my camera works just fine. But I want to go back to Jasmine 4.3 (LL), but when I install it again on MM bootloader, the camera is blurry.
The only way to fix the blurry camera is to install official firmware or MM rom such as Jasmine 6/7, or even official LL firmware.
I have no problem starting the whole process of unlocking the nite 4 since I've already done it a dozen times now. But while at work was wondering if anybody had an answer other then what I am doing.

If you're on a Marshmallow bootloader you can only use ROMs that are based on the Marshmallow bootloader. Jasmine 6.0 and up are examples of such ROMs. Paul Pizz and CM13 from 6/22 up are too. (Yeah, I know, so is the 6/20 version but that was so buggy that I don't even count it.)
Jasmine 4.3 and below were based on Lollipop bootloaders and need a Lollipop bootloader to work properly.
Yeah, the ROMs may partially work if you cross them up. But they won't be usable, with the big problem being data and the lack of.

Whats up with the MM bootloader??

Ever since i took that second step to getting the mm bootloader ive been having problems installing roms and kernels. The only rom i get working for the mm bootloader is dr ketans, where when i was on the lollipop bootloader i could flash any. When i flash others it just hangs on the boot animation. Can soneone explain to me why the mm bootloader isnt playing so nice with roms? And can someone also give my the simplest guide to go back to the lollipop bootloader? Thanks.
Can someone tell me whats the point of upgrading to it?
Is there anyway to go back to 5.1.1 If you are on 6.0.1? I bought. Note 4 Verizon yesterday on swappa should be getting it somtime next week. The device has marshmallow installed. I just need to know if I can downgrade to 5.1.1 then root and unlock BL. Iv done some reading thru the forums, if this has already been discussed then my fault, cause there's a good chance Iv over looked the topic. Thanks

If you're on a Marshmallow bootloader you can only flash ROMs that are based on a Marshmallow bootloader. If you are on a Lollipop bootloader you can only flash ROMs that are based on a Lollipop bootloader. It is entirely possible to have a "Marshmallow" ROM that has a Lollipop bootloader base. Some ROMs demand that you be on a specific bootloader. @chevyrhoad's Grace 7 ROM is one example, Jasmine7.0 is another.

Thank you very much. This is why i was having problems flashing different roms. It seems like the lollipop bootloader is more flexible with roms. I already downgraded back to the lollipop bootloader. Ill be sticking with the lollipop bootloader Thanks.

[q] lg g4 stock based rom

Hey guys, My dad is willing to update his LG G4'S version (Currently running Lollipop), I do understand a thing or two in rooting, custom roms and recoverys , however, I own a galaxy s6 - it has no AOSP Roms, only stock based. and my father is used to his phone as it is, I don't think flashing cyanogenmod will be a good idea, he likes the functions LG added and stuff like that( Yeah, I don't understand it too ). Are there any good MM stock based roms?
Thanks and sorry for my English
Cant u just ota official mm?
If not, what variant does he have? not all roms can be flashed.

Sorry for not mentioning - H815, Also, what is the newest official MM version (carrier-free)? I don't have any OTA's in my place currently unfortunately.
I use the stock MM ROM ver 20D listed in Android Development section, and it is lightning fast and smooth!

Well good news, you got the bootloader unlockable variant!
To be honest anything with H815 in it is what you can do.
You can flash stock MM (I'd reccomend v20h its located in the general section)
You can flash cm13,
Be free little birdy!

Should I upgrade to Official 6.0 first or just flash 6.0 AOSP CustomROM?

Hi, I'm new in here
This is my first thread
I'm confused what should I do before upgrading to Marshmallow firmware?
I mean we already have 6.0 Custom ROMs (tried marshmallow RR and then going back to CM 12.1)
and now there's official marshmallow firmware, then there's PAC-ROM that have updated their blobs (what is that) and updated MM bootloader. They said I need to have marshmallow bootloader
so what should I do to have marshmallow bootloader? what is the benefit/difference for now by having MM Bootloader on customROMs than last build?
sorry if you got confused too
I'm a big cm13 user. But right now I'm on mm stock. I think asus got it right with this upgrade. If I were you I'd go stock mm until the devs get cm14 out.

I'd go for stock MM

H811: Possible to downgrade from Lineage 14.1 to stock 20v?

I originally upgraded to the custom Freedom rom which is based on the stock H815 7.0 from stock marshmallow 20v. I had problems so I clean flashed the same developer's Despacito rom, also based on H815 stock 7.0. The problems persisted so I clean flashed LOS 14.1.
I would prefer to downgrade back to 20v but I'm confused about whether arb issues affect this scenario.
Update: I took a chance on downgrading since I couldn't live with the radio issues on the unofficial Nougat roms. Flashed a zipped stock official T-Mobile 20v and so far no problems. I'd still like to know why this worked but "rolling back" bricks the G4 on "official" stock.

Thanks for the arb specifics. Good to make a note of.
After I successfully downgraded to 20v stock I heard from the developer of the custom stock ROMs I'd had problems with. Turns out he (wisely) uses the 20v baseband and bootloader along with stock 7.0 ported from the H815. I would have relaxed more if I'd known that from the beginning. It's my understanding that developers who base their ROMs on Legacy or AOSP *do not* usually replace the baseband and bootloader when they flash a later version so that it is safe to drop back (within the type of parameters you describe above). I guess he followed that model.
It's always something.

actually we use korean port not h815 we tried and it gives lots of error and FC. i think h815 does flash bootloader.. us we didnt get any beta we use korean KDZ edited to work on h811 volte is missing 4G icon is missing at least on my end it is. and h815 had a beta wich is better then use korean port.
what issues were you facing.? am using h811 port because despacito has black on black text if you use dark theme.

The developer of Despacito, etc. contacted me and confirmed that he uses the Marshmallow radio and bootloader so that is why I was able to go back to H811 6.0 20v. I had intermittent issues with the sd card not being recognized and forcing a re-format.

custom rom with stock kernel?

Was wondering if I flash a 5.1 rom with an untouched stock lollipop boot image onto my G4 what the outcome would be?
Is there any lollipop custom rom that this would work with? I have tried this on my locked lg g4 BTW and no dice

1)
The 5.1 Rom is the stockrom for the G4 Series came out in 2015.
You can flash a 5.1 and it will be run, why not? But MM (6.0) is more G4 friendly, works more fluid...
2)
The only thing you must looking for is the correkt Modell, H815-H818 and so on....
What Android is on the G4 now and what is locked on it? The Bootloader or have a Provider Lock..?

It's a H815T with a locked bootloader and I root all my devices
I was hoping that imperium or some other stockbased rom with notable differences would have released a 5.1 version, but I think they started on MM. I actually tried to flash cm12.1 then my stock boot image lol. Had to wipe and restore plain old Genisys rom
It's network unlocked and I use Twrpinfish by @steadfasterX
https://forum.xda-developers.com/g4/development/locked-twrpinfish-locked-g4-devices-t3573048
My wish is at least to have a more 'stock android' ui and ability to theme (cmte,etc)
If I could boot a cm12.1 rom it would awesome :highfive:
