Sorry, no experience in the emmc field.. only an advice, the lack of 1,8v supply by the programmer or by the board, the board need to enable them probably.. -
If you power the eMCC from the programmer, you got to make sure the crystal on the board is disabled. 2 clocks won’t work. If the board is dead could be that the eMMC is dead or has bad BGA. There is a resistor on the data line like D0. Compare it to the resistors of the other data lines. If that resistor changes a bit of resistance, there will be no data transfer happening. Best to take the chip off and put it in an adapter.Comment

Hello all,
help needed.
I want to made backup of boot and all partitions from emmc desoldered from old phone.
So i have wired emmc directly to RT809h - Dat0, GND,CMD, CLK, VCC, VCCQ - on programmer sw set Smart Identify to EMMC ISP and voltage to 3.3V.
In Settings (N) i have set area to user, boot1,boot2 and EXT and vccq set to 1.8V (tested 3.3V too).
Problem is, that i still get Read Timeout Error
