Can this TWRP be flashed with "fastboot flash recovery XXXXXXXX"?

Sony devices use what is called "Recovery in Boot" meaning the recovery resides inside the boot partition. SInce there's no recovery partition to flash TWRP too and no way that i can see to add a recovery partition; which makes it much more difficult for the stock rom to boot with a custom recovery because the boot image fails validation.

OP's download link is dead. Anyone got a mirror?
I already got LineageOS installed and everything's running well, so I just wanted to replace LOS' recovery with TWRP to make (and eventually restore, if needed) a NANDROID backup. Would that work?
I've read TWRP on this device has issues with the data partition, so I don't wanna risk a hard brick just for a backup that maybe I won't even need 😅

    Err I see. Does that mean I'm not getting root on it? Kinda bought the phone assuming I could based on the bootloader unlock option and the various threads here...

    there's plenty ways to get root, after you unlock bootloader (eg: magisk boot patch)

    right now twrp is kinda like work in progress till i manage to get vendor_boot to works on a12 and 13, once i get that twrp will be a lot safer

    But do I understand it right, that you therefore can't use TWRP to modify your stock rom?

    There is an easy solution for that. Flash TWRP to the active slot. Follow My Guides to make a Magisk Boot Image and flash the Magisk Image after using TWRP within TWRP (select image).
    To use TWRP use ADB again. You can also change Slots using TWRP or Apps made for that to get around the bootloops. Not sure about the encryption but my Xperia 1 III has decryption no matter on which slot i flash.

    We can also trying to fiddle around with that:
