did you still have this problem? i just got my unit recently. it came with qwrt by default. but for some reason im mess up with it. and try to find some new image. from all the test ive been doing. only qwrt feel very nice. its just boot up and connect to network below one minute. here i give you the link where i found the image. i dunno who create this list. but im very grateful https://alist.hutao.xin/H29K/%E5 ... %90%ABV1.3%E5%89%8D
if you can't flash the image from flashing menu on openwrt webui. you just need to flash with rkdevtool. in that link the tools is also provided. just look above those folder. its really nice image for my h29k v1.3 and fm350-gl
