I managed to flash openwrt archer c7v1 from the 16th to the wdr7500 v3. I preformed the flash from uboot serial console.
The v3 only has 8mb flash
7500v2 (Chinese version) is 8M flash therefore its firmware possible could be flashed on 7500v3.
I have used serial connection to try a 7500v2 OP firmware on my 7500v3.
uboot seems to be erased.. when flash completed and 7500v3 robooted there was no output in serial connection anymore.
I think I need a ttl tutorial.. or someone please tell me the right command..
