Blackbox mk3 stuck on v2.15

[RunAroundguy]

as title says one of my blackbox mk3 is stuck on version 2.15

loaded up zbootloader v2.01 and tried to update to v2.225 (blackbox_mk3_unified_v2_22_5) with just the blackbox mk3 hooked up with no grip plugged in and get hit with the "device signature not correct".
flashing my other "right" side black box went flawlessly.

as i saw theres a common request for the .op1 save file ill attach it as a just incase

just a follow up with some screenshots. verified again that the box externally looks like a BB MK3 box with the black housings and red button. bottom also says mk3 on it.

Thank you very much
took me a minute to realize i needed to load the .op2 then load the v2.225 firmware then flash.
everything took well and is operating correctly while being on firmware v2.225

again thank you very much.
