I find it hard to believe that Renesas would have as many as 6000 failures or that they would allow these chips to escape their factory.  The reason I'm interested is that if the chips were made by a non Renesas company, it's possible they have a solution and secondly, how did they get the design files?

> Nope, they don't have beach sand.  They're functional to a point.  They were either made by Renesas or someone with the design files and the equipment to make them.  However I guess the chance that they were made by a legitimate manufacturer must be pretty slim as we wouldn't get 100% failure rate if they were legitimate.

What do they do right and what do they do wrong? 

If they are largely functional but are failing some small detail it is possible these are clone chips, a fresh design, not a literal duplicate of the original device.
