Any hope for those of us with SM-G781? Just bought it and it was fully updated so I'm assuming its not unlockable yet, but is there any hope for unlock and lineage capability eventually?

This thread is not for FE, if you are on G781U/U1/W can be unlocked on v1 or v2 bootloader, if you are on G781B find my r8q twrp thread.

    So, the bootloader unlock process is a paid service? I'm confused, can't we do it ourselves? Is the only solution to pay for it?
    Ok you can do it yourself. Buy international device.

    Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

    Code:
    * Your warranty is now void.
    * I am not responsible for bricked devices, dead SD cards,
    * thermonuclear war, or your getting fired because the alarm app failed. Please
    * do some research if you have any concerns about features included in this ROM
    * before flashing it! YOU are choosing to make these modifications, and if
    * you point the finger at me for messing up your device, I will laugh at you.
    Note: My TWRP builds are free I take no money or selling them, The new builds support US devices unlocked before 9 november or added upon request.

    Supported Models:
    Galaxy S20 Ultra G9880, G988N, G988U, G988U1 and G988W.
    Galaxy S20 plus G9860, G986N, G986U, G986U1 and G986W.
    Galaxy S20 G9810, G981N, G981U, G981U1 and G981W.

    US/Canada bootloader unlock thread:
    here

    Download & Guide:
    1. Unlock your bootloader.
    2. Download S20: x1q, S20+: y2q or S20 Ultra z3q.
    3. Reboot to download mode and flash vbmeta_disabled.tar in AP slot and reboot. Device will reboot to stock recovery mode prompting you to wipe data so wipe data and reboot to download mode again.
    4. Put the TWRP tar for your device with Odin in the AP slot and click start.
    5. Reboot to recovery via recovery key combo.
    6. Disable encryption:
    Or:
    - Go to Advanced > Terminal, type: multidisabler.​
    If vendor complain about free space left on device, will attempt to resize vendor. and it ask to - Run multidisabler again!.​
    - Type: multidisabler again. will see - Finished. when done.​
    7. Go back to Wipe > Format Data > type yes.
    8. Reboot to recovery.
    9. Flash magisk apk in twrp.
    10. Reboot to system, Enjoy.

    Note:
    To disable encryption manually:
    You need to replace fileencryption=ice with encryptable=ice only in userdata line (maybe rest lines) in vendor/etc/fstab.qcom
    To avoid stock recovery restoration manually:
    Rename system/recovery-from-boot.p to recovery-from-boot.p.bak
    Support:
    Live support is available via #twrp on Freenode with your IRC client or just click this link.

    Thanks @afaneh92. For others' help, if anyone finds it useful, I flashed TWRP on my G986U1 using this sequence:
    • Unlocked bootloader as I described here.
    • Flashed vbmeta from this thread using patched Odin.
    • Flashed TWRP using patched Odin but did not auto-reboot.
    • Rebooted into TWRP using key combination.
    • Format data
    • Flashed multidisabler from OP in TWRP.
    • Format data again, just to be safe.
