My question is what kind of tools, programmers, hot air settings, techniques are you guys using to play with eMMC's? Any weird failure modes? These days eMMC is in a lot of devices and I should be getting some these devices on my bench.
I had a RCA smart tv main board in my junk bin that had some Toshiba eMMC FBGA153 on there. So I took it off in order to read it. It seems that these eMMC's aren't only soldered on, but also glued to the board? Anyway, I've probably had the board for 4 years kicking around in the pile, so that probably didn't do any good either. So I put it in the FBGA153 programmer, found the correct eMMC in the settings and? Nothing.
The pins got detected correctly, but it is timing out for a read / write in all 3 modes 1bit/4bit/8bit. There was absolutely nothing to save in Boot 1 and 2, User etc. Always get the same error. I've tried to read them individually, no bueno. 
Not sure if the eMMC was bad to start with, or i burnt it off (took like 3mins on 400C to get it off the darn board). It wouldn't move off the board easily, so I decided to jam my tweezers between the eMMC and the board and pry it off. That's how I noticed that the eMMC was actually glued on there.
