Hi

we have several devices TL-WR840N<W> ISP preset function  we have customized our firmwares and loaded into them.. following the tp-link Brasil tutorial with .bat files

to load custom.bin files.

Now we nee to fully restore it to factory version, we have tried upgrading the original BR firmware via web interface it loads and installs everything but after reset and reboot

it comes with ISP custom data, we need to either change this custom data to another data (which we have tried doing following the same pdf tutorial with .bat files and new custom ISP firmware.. but after waiting the 5minutes requested and reseting the router it still comes back with first custom data.

i kindly request tp-link to make available the full tp_recovery.bin firmware for this exact models sold in Brasil, so we can try to re-flash it via tftdp

as we have tried flashing the original firmware via tftpd on ip 192.168.0.66 tftpd server it loads 100% and reboots the router, and after that all we have is flashing lights on the router, and christmas is still too far away
