The easiest way to get into MaskROM is to short the 2 pins mentioned in this post.

By shorting the 2 pads in the red box, eMMC is disabled and iHost will boot off SD card. [Sonoff-iHost-Maskrom] If you want it to always boot to sd card, just solder them together with a short wire. Or you can just short them together with tweezers or something metal for the first ~5secs during power on. Or in my case I installed buttons, to make testing either eMMC or SD easy.
