Redmi 6 JZ050

[BiNaRs]

Phone worked, but locked on mi account.
RIFF v1, connect RJ-45
emmc Micron JZ050 not detected.
Maybe another pinout?

[Legija]

Have you added pull up resistors ?

[BiNaRs]

Yes, CMD & DAT - 100ohm, clk - 4.7kohm

[Legija]

Better to use 100 ohms for clk too.

[BiNaRs]

with 100ohm for clk not connect (
Maybe another pinout for micron emmc?

[Legija]

Can You please post logs from connection attempts ?

I soldered to the board, connect only clk, cmd, dat & gnd (vcc & vccq from usb), and now:
