Easy-JTAG eMMC HTC problem?

[Elliot.]

Just attempting to read the data from a HTC M9 0PJA100.

I have had one of these before where it wasn't successful. The partition information does not get read in and it says:

CMD Pullup Level:1722 mV
CMD Active Level:1794 mV

Done.


ALSO the below when I select more debug data:

There are a couple of other weird things on this one:

1. The NAND only ready for 128MB then stops with a read timeout error.
2. The data itself (hex) contains only "ER 18" and then the rest of a sector is zeros.
3. The fact that a previous case on this model came up as the exact same (even device serial number) and did the exact same, could it be something with the SK-Hynix chips that they are protected from being read?

If this is posted in the wrong place sorry.

[pai_d]

you have bad connection, bad voltage, or bad EMMC.

Did someone ever resolved this one, I also get "ER18" in the result data from two different chips

Hi krillekrokodil, I had to conclude this one as a dead eMMC, it may have been the eMMC that died, I may have applied too much heat to the device, impossible to say exactly what.
