Build for TP-Link Archer C1200-AC1200

Well, I just bricked my "tp-link Archer C1200 EU V2" router.

I flashed the "Tenda AC9 OpenWrt" firmware on my router (as the chips seem to be the same), and could sucessfully boot OpenWrt on the Archer C1200 once.

After a long story(*), I basically failed to backup my factory firmware and flashed my trx and nvram partitions with garbage. Now, I can't get the bootloader to pass a partition check whatever firmware I would then flash:

...
Reading Partition Table from NVRAM ... OK
Parsing Partition Table ... OK
[NM_Error](nm_api_readPtnFromNvram) 00134: partition name not found.
...

If anyone happens to be able to dump their factory firmware or knows how to extract the trx binary from the firmware available on tp-link official page or has any other idea, I'd be happy to try to unblock my router. And ideally try to have OpenWrt work on it !
