PandoraBox R20.3.7 sysupgrade firmware for the Phicomm K2P router, MediaTek MT7621 platform, SquashFS image, packed in a 14.6 MB RAR archive. Sysupgrade images are installed from a running OpenWrt-style system or through a bootloader such as Breed. Extract the archive and confirm the image matches the K2P hardware revision before flashing. Back up the full flash, especially the factory partition holding wireless calibration data, since losing it degrades Wi-Fi. Use a serial console for recovery if needed.
