Hello, so I purchased a Canadian Tp-Archer C7 v2 and I'm having a bit of difficulty when trying to flash to the Canadian firmware. I've seen a post (https://community.tp-link.com/en/home/forum/topic/158973?page=1) with regards to a user facing an identical situation (same firmware, version, router still works, bought in Canada, etc.) and he/she was able to receive assistance from a representative who was kind enough to pm them a solution that seemed to work - rather unfortunate as I would also have liked to know, hahaha. Any ways this seems to be a common problem and I was hoping I could ask the community for some help on the issue. I have tried some of the strategies used by the OP in the link such as renaming the file in hopes of tricking it into flashing the correct Canadian version of the firmware but to no avail. In addition, I would also like to point out that the router is still functioning with the current firmware - note: it has been updated since its purchase so it's possible that is has been flashed with the latest v2 US firmware by mistake. To provide a bit of context to my situation when I go to try and put the correct Canadian firmware I receive "Error code: 18005. Upgrade unsuccessfully because the version of the upgraded file was incorrect. Please check the file name". Any assistance which could possibly help me get the correct Canadian firmware flashed would be greatly appreciated, thanks. My router details are as followed if they are helpful:

Model/Modele: Archer C7(CA) Ver: 2.0 (as per bottom of router)

Firmware Version: 3.15.3 Build 180114 Rel.39265n

Hardware version: Archer C7 v2 00000000
