[Q] Some questions after reverting to STOCK ROM

Like many of you I haved rooted, unlocked with FreeGee and installed many custom ROMs on my LG Optimus G.
Now I decided to go back to STOCK ROM, I followed this GUIDE to flash KDZ, everything worked OK, phone works like it has to.
So if everything works what are the problems, well ... I have some questions for you:
1. Many of you are writing in the forum that after flashing the KDZ the phone will revert back completly to stock. Will it revert bootloader back to stock too?
2. If the answer of above question is that it will revert back to stock, then in this forum someone says that bluetooth gets its MAC adress from bootloader. Why my bluetooth MAC still begins with 41:4E ? Is this one of the compromises when you unlock the bootloader?
3. Is it possible that in flashing KDZ guide I did something that will not flash the bootloader?
4. Is there a way to fix bluetooth MAC adress?
Thanks in advance for your answers.

Downgrading Verizon SM-J337V (Galaxy Eclipse J3 gen 3?) back to Oreo

I have a Samsung sm-j337v on Verizon that I have been mostly happy and productive with until the forced OTA Pie 9.0 upgrade. Since the upgrade, the phone is noticeably slower and multitasking is a real pain in the rear.
I'd love to go back to the Oreo that the phone shipped with, but don't know if that's possible. As far as I understand it, doing a factory reset will simply leave me with a clean slate version of the currently installed version of Android which is 9.0.
Is there any way to accomplish this or am I stuck with

Hey, You can use odin to downgrade your phone on oreo but did you try a factory reset before go back to oreo ?
If you really want oreo try this fimware : https://androidfilehost.com/?fid=6006931924117896042

Question MSM or return to stock on Linux

I have been reading that the best and easiest way to return a Oneplus 9 pro back to stock OS and lock bootloader again is to use the MSM tool. I've downloaded it and it looks like its a windows only tool.
Does anyone know of any other methods to revert the 9 pro back to factory when your flashing computer is running Ubuntu as the OS?
Longer story:
Got the 9 pro last week. unlocked, bootloader and rom is lineageOS. Realized the physical dimensions of the phone just don't work for me. Going to return it and purchase the 9 instead. I need to get this thing back to factory within the next couple days.

Found a way to accomplish my goals of getting back to stock.
While in LineagOS bootloader I did the adb sideload like I would for loading lineagOS ROM.
Then side loaded the stock build.zip. This took care of reverting the bootloader as well for me. so now all I have to do is lock to bootloader itself and I should be back to stock so I can exchange this thing for a smaller sized 9.

You don't need to LOCK the bootloader before using MSM tool. MSM tool does that for you.
And, especially if your ROM is modified or you're running a custom, don't attempt to LOCK the bootloader, it will probably brick your phone.
