INTENSO 480GB SSD HIGH SM2259

I have this intenso SM2259 I loaded the loader and built the translator, but when reading it gives me many ECC errors and it is very very slow, they advised me to heat the nand chips up to 160°, but I was wondering, do the chips have to be heated constantly for the whole reading phase, or do I have to heat them and then connect it and read it?

Yes they do need to be heated constantly. If you are also getting errors while building the translator, heating the chips during that phase can also help. Personally I would start at a lower temperature and then work you way up depending on how the chip reacts, until you find the 'sweet spot'.

Unfortunately even with the heating method and air cool spray nothing changes at all, I think that the state of the nand is really bad, so the customer will have to settle for a partial recovery.

Sometimes that is all we can do.
