Citazione di: 'presola'After many attempts to freeze particular parts of the motherboard, I've came to the conclusion that the problem is with the NAND flash memory chip (in my case a Hynix H27U1G8F2BTR, see the picture - it's the one I'm pointing at).After freezing the chip with some pressurized air in a can, the NAS boots up just fine and works perfectly until a restart... I tried updating to the latest firmware, but since it doesn't solve the issue, I'm fairly confident this is a hardware problem. Unfortunately, none of my programmers support reading and writing NAND chips, so (for now) I can't say if the whole blue blinking lights issue would be solved with a new chip containing the backup from the original one.In any case, I'd love to hear feedback in any form - if freezing this chip makes your NAS work too, if you have access to a NAND programmer and can make the experiment, etc. I'll continue looking for a programmer myself and will update the thread with my findings.[...]I don't really think a chip that's rated to be usable in the temperature range from 0 to 70 degrees Celsius would be overheating in any form. See the chip's datasheet here: http://natisbad.org/NAS/refs/Hynix_NAND_128Mo_H27U1G8F2BT.pdf (page 13, the NAND in my NAS ends with a C, so that's Temperature Range Option 1).[...]When using the pressurized air in a can, the chip freezes and it's temperature falls below 0 °C. That's when this joke of a NAS starts working. No amount of passive cooling would solve this issue.
