Tried to compiled for K26USB-MIPSR1 e (VPN). Result size is 6.79MB.
router model: ZTE ZXV10 H618B
Any idea why?
Only way to know for sure is look at the serial output. Otherwise we can make all sorts of guesses, you still have to de-brick, try again. And if it fails again, continue to make guesses until you have a serial out to see what the router is spewing :)
