HTC One M8/M8s

[kwaku85]

Hello supporters!
I'm currently working on M8 and M8s modells, trying to repair them after EMMC damage.
Do You know boot order? Whitch partitions are needed to boot phone and whitch one are restricted to modify (IMSI lock like M7).

Keep backup "Board_Info" partition.

Hello again
I can't make EMMC pinout for M8_UL board. Can't find CMD and DAT0 lines. Did I miss something, or EMMC lines go directly to CPU in One M8?

Nevermind, I have find all signals.

I give up. I have read flash from working phone excluding userdata partition and flash to dead M8s (M8_QL_UL) and still dead. EMMC changed, board looks ok and nothing. Originall EMMC chip has problem with storing data. If I flash it- controller wipe memory (write zeros) but can't store flashed data. New Chip work's fine, but phone can't boot even with copied all partitions from different working phone.

Can you share pinouts of M8s?
Can't find anywhere.
Thanks.

Here is pinout made by me.
My problem was mem configuration. Thanks guys
Solder only CLK DAT0 and CMD. To connect You need only microUSB cabble. Try with or w/o battery.
