Hello,
Just got a new N20 Ultra and haven't even powered it on yet because I don't wanna mess anything up!

If I unlock bootloader and root can I still upgrade to the latest Android version through ODIN or will.it make me upgrade the bootloader to version 2?

Just to make sure. You said you patched bootloader v2. Are you saying that although you did patch bootloader v2 that you cant install original stock rom while keeping the bootloader unlocked?

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.

Supported Models:
Galaxy Note 20 Ultra N9860, N986N, N986U, N986U1 and N986W.

Big thanks afaneh -

I was able to flash twrp, but my odin 3 v3.14 did not recognize multidisabler-samsung-3.x.zip that I downloaded the attachment from the page that the link took me to. Am I missing something?

    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

    How do I unlock bootloader on sm-n986w? OEM unlock is not in the dev option list
    US/Canada devices has no oem option. Can be unlocked via some services. I cant discuss here in xda because I didn't got approved yet to post. You can try to contact out of xda.

    Stuck on ...
    7. Disable encryption!, flash multidisabler-samsung-3.x.zip and format data in twrp and type yes.

    Is disabling encryption and installing the multidisabler the same, or is that two steps? Any elaboration would be helpful.
    Yes same thing.
