Hello my friend first of all thank you for such a wonderful forum, i'm into cellphone repair and electronic debugging. I own an Rt809h but is it possible to repair cellphones with Rt809h using EMMC pinout D0, CMD , CLK , or I need to buy a box like UFI BOX or EasyJtag. I started thinking a bit and rt809h has the capability to write into these EMMC memories on partitions BOOT1 BOOT2 and user area, but I don't understand why other boxes like ufibox or easyjtag appear. Please if you can clarify and see if we can use rt809h or make a modification to use with cellphones I would be grateful.

RT809H is not designed to repair cell.

UFi Box is a powerful EMMC service tool. This tool can read user information, as well as restore, resize, format, erase, read / write and update EMMC firmware on Samsung, China phone SK Hynix, Toshiba, Kingston, Micron and other manufacturers * chips.
