Fried eMMC?

[belfastraven]

With the eMMC inserted and no SD card, my pbp goes into maskrom mode, doesn't matter if I use the recovery button or not. I can't seem to do anything in this state, I can't even reset it:

Code:

matega@neofelisnebulosa:~/build/rkdeveloptool$ sudo ./rkdeveloptool ld
DevNo=1 Vid=0x2207,Pid=0x330c,LocationID=102    Maskrom
matega@neofelisnebulosa:~/build/rkdeveloptool$ sudo ./rkdeveloptool rid

matega@neofelisnebulosa:~/build/rkdeveloptool$ sudo ./rkdeveloptool rci

Opening loader failed, exiting download boot!
matega@neofelisnebulosa:~/build/rkdeveloptool$ sudo rkdeveloptool rd

If I insert my 16G Samsung uSD card, boot it and execute `reboot loader`, it gets into loader mode, but then the only thing it sees is the uSD:

Code:

matega@neofelisnebulosa:~/build/rkdeveloptool$ sudo ./rkdeveloptool ld
DevNo=1 Vid=0x2207,Pid=0x330c,LocationID=102    Loader

I've tried swapping and switching the eMMC multiple times, I'll make some more tries but I'm fairly confident I toggled the switch correctly  The USB adapter might as well have disintegrated, I can't find it anywhere.

Hmm.. RIght now I can't really open my pbp to try removing everything--hands not working very well, or I'd try for you to see what a working EMMC should look like.  I'm curious, though,  If the PBP is in maskrom mode,  and doesn't think there is any EMMC or SD card installed,  you should still get some kind of ID back from the SPIf lash.... but it looks like that is not happening.  If you have a chance can you  get into maskrom mode without SD or EMMC installed,  and see if you get anything different?  That might give some insgiht into whether the EMMC is being seen in any way.    You might have to press recovery to get to the spi flash--I can't remember off-hand....
