TP-Link WR2041N V3

I have this router, the original firmware are all Chinese which is kind of inconvenient as i can't understand single word of it. I wonder if any OpenWrt firmware compatible with this router

It has : Winbond 25Q15DVS1G flash memory, Atheros TP9343 Wireless Chip, Zentel A3S28D40JTP-50 DDR1 128MB 8Mx16 200MHz

Someone told me that this should be compatible with TP-Link WR941N V6 but when i tries to flash OpenWrt firmware for that router to my router, its doesn't flash and getting error.

Then it's probably not compatible...

Which FW did you try?
