I am rooted on AOSP currently and have the 10j bootloader and modem. If I upgrade to 10p/q and keep root and TWRP will I still be able to flash AOSP roms such as lineage despite not being able to downgrade stock firmwares? Thanks.

From what I've read, as of right now you cannot use AOSP builds on anything newer than 10K. I haven't kept up with it though so maybe there is an updated method

I currently have AT&T stock (I used to have a custom ROM then had to flash to stock ROM to be able to flash to another custom ROM--however, I accidentally flashed a newer version of the AT&T stock ROM which locked my bootloader and I could no longer flash to a custom ROM). I updated my AT&T stock ROM recently and now my back/menu buttons don't work, so I want to see if I can flash to a custom ROM now.
I don't remember the procedure to flash a custom ROM--do I first need to get root in order to unlock the bootloader to be able to flash ROMs (i.e. if I have root then I am guaranteed to be able to unlock bootloader in order to flash ROM)? Is the baseband version the only thing that determines whether I can unlock the bootloader and then be able to flash ROMs?
I currently have OK2 as broadband version and checked one of the stickied threads which said this:
" ROOT
OK2 -- No direct root method. Must Odin OC4 kernel, use Kingroot, then Odin OK2 kernel back."
Does that mean what I have to do is use Odin to get OC4 kernel, then use Kingroot, then Odin OK2 kernel and then I will be able to have root, which means I can then unlock my bootloader and be able to flash to ANY ROM (not just TouchWiz-based ROMs)? Is there anything else I need to consider or is this 100% foolproof? In the future, what should I be careful of in order to prevent getting my bootloader locked again--just that I don't flash a stock (AT&T) ROM that is known to lock back the bootloader?
Thank you all!
There's no way to unlock the bootloader if you have updated your device to the lastest firmware version. The only thing you can do is flash SafeStrap and use Stock Kernel Based ROMs which are compatible with Safestrap.
As regards to the procedure of rooting an OK2 firmware, I'm afraid I won't be able to help you.
Have a happy new year.

I was just about to sit down and flash a stock ROM. Can you explain what you mean by this? Did you flash OK2 and it caused you a problem?

It was a while ago but I used to have I believe an MDL broadband version which meant I could flash any ROM available. I tried a different ROM, didn't like it, then decided to flash back to the stock ROM but accidentally flashed a newer version of it, which meant that my bootloader is now locked. With a locked bootloader, apparently I can only flash to a newer stock ROM (not other ROMs like Cyanogenmod) via Safestrap.
I think if you don't have the MDL broadband version you shouldn't worry about it anyway because it is locked and you will only be limited to flashing stock ROMs.
Slight correction
The previous entry is not entirely correct. Like the OP, I was originally on an unlocked bootloader on my i337. I'd purchased my i337 on the first day and eschewed OTA updates. I wanted to try a touchwiz based ROM, Hyperdrive, and in doing so I recall flashing the stock NB1 firmware. Every firmware beginning with NB1 has a locked bootloader and there has been no progress for more than a year in unlocking the bootloader again. This can limit you to either stock ROMs OR other touchwiz based ROMs like Hyperdrive. I love the Hyperdrive ROM (now on release 21) but its developer has moved on to a newer phone, so it's stuck at Android 4.4.2 and no one has picked up the project in many months. There are several other touchwiz based ROMs for the i337 version of the S4 which I have also tried but I prefer Hyperdrive's myriad customization, even without proper patching. I'll be moving on soon to the Nexus 6P as my daily driver, but would very much like to keep my S4 up to date with a custom ROM. Given the number of people that have been in this same situation, where a newer stock ROM from AT&T locked a previously unlocked bootloader, it's been surprising that the issues have not been overcome on a phone as popular as the Galaxy S4 was and continues to be. I've seen unlocked versions of the S4 selling for just under $400 in the last week of 2015.
Use the desktop version of Kingoroot to root and use Super su and update the binary. Don't forget to hit thanks if this helped.
The bootloader for the at&t s4 was never unlocked. The MDL bootloader had a flaw in it that allowed you to use LOKI which is a lock bypass, not a way to unlock the bootloader.
Been off this thread for awhile (you know how life gets in the way) and was wondering if there are any meaningful upgrades to an S4 with 1545VRUGOF1 rooted via Flashfire. with stock.

If you want marshmallow, then custom ROMs are the only way to get it.
Which s4 do you have? Isn't flash fire for the i337?

At the time, Flashfire was the only path to root
Look here for a possible answer: http://forum.xda-developers.com/galaxy-s4-verizon
Any guidance? I have the VRUGOF1 Bootloader and consequently was only able to root with Flashfire. Not sure if there has been any development to allow Marshmallow to be put on this device

Yes, there are ROMs for that device. But you can only flash with a custom recovery so you'll have to find one.
Look in the Verizon forum. This forum is for the international version of the s4.

Maybe I'm not being clear, but I was uder the impression if you have the OF1 Build you can only root with Flashfire, and, you cannot install CWM or TWRP as it will brick your device. I am not looking to add another ROM, I am fine with stock. My goal is to see if there is a way to go from Lollipop to Marshmallow safely given my specific device parameters

If you can't install any custom recovery, then there isn't any way you can.
There is no official TouchWiz Marshmallow ROM for the S4, as such, the only way to get marshmallow is through a custom ROM.
A custom ROM can only be flashed via custom recovery.
Ergo, if you can't flash a custom recovery, there is no way to get marshmallow.
The Verizon OF1 bootloader is locked and not exploitable. Only the MDK bootloader had that luxury. You also cannot downgrade to it. If you want to flash a ROM other that stock head to the Verizon Galaxy S4 development forum and read up on SafeStrap and ROMs that can be installed with it. A custom recovery such as TWRP is not able to be installed on your device. Because of that ROMs such as CM, JDC custom ROMs, etc. are out of reach for you.

Thanks
So to summarize, since I am on the OF1 build and could only root via Flashfire, the bootloader remains locked...consequently I still cannot flash TWRP or CWM, and as you put it, out of luck to get Marshmallow.
However, has anyone successfully used Flashfire and Xposed? I saw it on another thread: https://www.reddit.com/r/AndroidQuestions/comments/406o9w/verizon_galaxy_s4_unlocked_bootlaoder/
but there was no definitive conclusion that it was successful. Anyone have any direct experience with this? Since Safestrap and Flashfire are both custom recoveries installed alongside of your locked bootloader, do either work to get to Marshmallow?

You are a little confused. SafeStrap is not a custom recovery so to speak, TWRP is. SafeStrap allows the installation of some mods, etc. on devices with a locked BL. A quick look in the Verizon S4 Android Development forum does not show a MM build that can be installed via SS, only LP builds.
The issue with a locked BL and SS is you cannot install a different kernel which limited what could be installed.
I saw a set of OF1 instructions out on Stang5litre's OP for his ROM. Has this been validated as a stable rom for those of us on OF1?
I am running NATF's Megarom 5.0 right now. Is there a 10p rom that I can install that doesn't have anti-rollback so I can go to CM14 or something later on? I see that 10p will stay rooted if manually flashed in with TWRP, so I am wondering if the anti-rollback would be in there. Thanks.

I'm not 100% but as far as I know the ARB is baked into the stock firmware so I don't think that's possible as of right meow
NO! Do not upgrade to 10P if you want to flash other ROMS. I'm on rooted 10P and flashing other ROMS does not work. Yet.
Actually if he wants to go to a current AOSP ROM, he will need 10p firmware. But yes, if you flash the 10p firmware, you can't use any of the ROMs that are based on 10k or 10l.
As for ARB, research is being done on a safe way to run 10p without incrementing ARB. But for now, if you flash the boot stack ... you are all in on 10p
There are no ROMS running on 10P kernel. And you can't flash Lineage which will be the ROM we'll need four years from now.
I just came from Galaxy S3 running Nougat. LOS ftw.
What do you mean we can't flash lineage on 10p?
Flash it and find out. The phone doesn't boot past the LG screen.
I have Custom ROM stock nougat
Can I install only the MM bootloader, do full wipe, and install a custom MM ROM, just for recovery?
Downgrade for recovery?
I'm confused about what you want to achieve, are you asking if you can downgrade to stock marshmallow from stock Nougat, to flash a custom marshmallow ROM?
If so, you could downgrade, but I would strongly recommend not using OTA updates on the stock marshmallow ROM if you downgrade, else you may hard brick your device. In most cases, you can't downgrade the bootloader in fastboot.
I'm not sure what you are asking for about recovery, can you elaborate?

You can even stay on nougat firmware, there's no need to downgrade as nougat is official released and available for all countries
How do I know which bootloader do I have? I'm currently running build B35.
Can someone direct me to a thread how to flash universal bootloader and modem?
If I use bkores flash toolkit, it said you have to flash universal bootloader, modem along with Rom and Gapps but in which order?
If using twrp for future flash do I need to flash universal bootloader and modem every time I switch ROM?
I'm not an expert but here's what I understand.
1. You don't have to worry which version you have unless you're flashing a custom ROM, usually for Nougat you want the B15 and for Oreo you want the B35.
2.Universal Bootloader>Modem>ROM>GApps>Magisk/SuperSU
3.You only need to flash it once if you're switching ROMs with the same android version.

If you haven't you need to unlock your bootloader before you can start flashing custom ROM. You can find a guide on how to do it here.
