Xiaomi Router 3 Pro (R3P)

reading this topic I have installed developer ROM on this router and SSH daemon who allows me to ssh to the router

now there is warning about chip version and when i checked mine i have
dmesg | grep 'Manufacturer'
[ 3.340000] NAND device: Manufacturer ID: 0x2c, Chip ID: 0xda (Micron NAND 256MiB 3,3V 8-bit), 256MiB, page size: 2048, OOB size: 64

so i have version 0x2c which according to this article has problem with openWRT firmwares

what I need to know :is there openwrt firmware version for this router which works without problem also with mine version of chip?

if not I would appreciate if someone could tell me how to install FTP app on the router having only XIAOMI developer rom and ssh access.
