Need AC9V1.0_FW_V15.03.05.19_multi.bin for TFTP recovery (Tenda AC9 V1)

My Tenda AC9 (V1 hardware) is stuck in TFTP recovery mode (blinking blue).
I need the OEM recovery firmware:

AC9V1.0_FW_V15.03.05.19_multi.bin

Tenda’s site is down and all mirrors are dead.
If anyone has this file backed up, please attach it here.

Thanks.
