Flashed i226-V firmware on i225-V, rollback mode does not work

[NRGSupport]

I copied an existing nvmupdate.cfg file and forgot to replace the device id 1573 (i225-V) with 125c (i226-V). When I ran nvmupdate64e.efi by accident on a system with multiple i225-V, it replaced the i225-V firmware 1.87(1.57) of one network controller with the i226-V firmware before I noticed my error. The flash tool created a backup of the old firmware, but when I try the rollback mode "-r", it always ends with "Flash update failed" at 30%. When I add the line "IMAGE DOWNGRADE: TRUE" to nvmupdate.cfg and use the regular update mode "-u", I can see the controller with version 2.54(2.36) and a status of "Update available". I start the update, but it always ends with "Device update failed" followed by "Warning: VPD area not valid". Neither "-f" (Force the NVM update) nor "-sv" (Skip verification) helps.
