Any significant chance of bricking devices with this mod? I sent 30 units to be moded and 6 of them came back "dead" 
That is 20%! Basically they appear to be hashing in cgminer but no shares are submitted at all. All 6 units were working fine at 850 Mhz before the mod. If anybody experienced something like this before, please let me know what you did to solve it.
