The device is: http://www.agrade.com.hk/goods.php?id=5021

Got it from ebay months ago but it didn't worked with my 3g (MD300) so the Chinese gave it for free.

The chip says RT3050F but Uboot says 3052

I tried the following images:

openwrt-ramips-rt305x-3g-6200n-squashfs-sysupgrade.bin
openwrt-ramips-rt305x-all0239-3g-squashfs-sysupgrade.bin
openwrt-ramips-rt305x-hw550-3g-squashfs-sysupgrade.bin
openwrt-ramips-rt305x-mofi3500-3gn-squashfs-sysupgrade.bin
openwrt-ramips-rt305x-wl-330n3g-squashfs-sysupgrade.bin
openwrt-ramips-rt305x-wr512-3gn-4M-squashfs-sysupgrade.bin
openwrt-ramips-rt305x-wr512-3gn-8M-squashfs-sysupgrade.bin
openwrt-ramips-rt305x-vmlinux.bin

None worked, the last one is the only one that says "Bad magic number", the other ones say "wrong image".

Any advice to get this running with openwrt?

Thanks!
