MichaelBurrola,

I am hestiant to upload my partitions for legal liability reasons.

However, I suspect I may be able to help you another way, by using fastbootd commands and the OTA.

Are you sure you are in fastbootd mode, and are using an up to date fastboot? (older versions do not support dynamic partition commands!)

Here is a good source for fastboot.

Fastboot tutorial

The dynamic partition system was designed to save space by allowing adjustable partition sizes.

In order to implement it, Fastboot was broken into two pieces: Fastboot and Fastbootd.

Fastboot is the initial loader which handles only non-dynamic partitions.

It is a black screen with red and white text which displays facts about your device, and has controls "press volume key to select...".

Fastbootd is the second stage loader, which can handle the dynamic partitions.

it is reachable by the very poorly named command

fastboot reboot fastboot

(which should have been named fastboot reboot fastbootd).

It reboots to a special version of the Recovery mode, running Fastbootd.

It is a black screen with the one plus logo and the word "fastbootd" at the top, and some touch menus.

Recovery lists "reboot to fastboot", which goes to Fastboot mode.

Recovery also lists "reboot to recovery" which goes back to Recovery without Fastbootd.

Note that the text "fastbootd" is missing from the top of the screen when in recovery only mode.

Boot the phone into fastbootd mode by:

booting into recovery mode, by holding power and volume down during boot, then

rebooting into fastboot (only) mode, using touch menus: advanced, reboot into fastboot, then

connecting usb-c to a computer and rebooting into fastbootd using the poorly named command:

fastboot reboot fastboot.

Next run

fastboot getvar all

check which slot is active (you could attempt to switch slots, but that didn't fix it for me)

and check your partition list against mine, particularly looking for your slot's set of super's sub-partitions

(assuming slot b) system_b, system_ext_b, odm_b, product_b, vendor_b

-cow (Copy On Write) partitions are unneeded and usually need to be deleted for space.

fastboot delete-logical-partition system_b-cow

Create any missing sub-partitions manually

fastboot create-logical-partition system_b 0x10000

fastboot create-logical-partition system_ext_b 0x10000

fastboot create-logical-partition odm_b 0x10000

fastboot create-logical-partition product_b 0x10000

fastboot create-logical-partition vendor_b 0x10000

(I don't believe the size must be correct, as they will resize when you flash them)

And then flash the partitions using the extracted OTA files from OnePlus

(system_b, system_ext_b, odm_b, product_b, vendor_b)

fastboot flash system_b system.img

fastboot flash system_ext_b system_ext.img

fastboot flash odm_b odm.img

fastboot flash product_b product.img

fastboot flash vendor_b vendor.img

You probably don't need to worry about boot_b since you have fastbootd working.

Also vbmeta and vbmeta_system (verified boot metadata), since verified boot turned off when your bootloader unlocked.
