Sandisk SSD Plus SM2246XT

[Mike - USBRecovery.co.uk]

This was supposed to be a simple loader upload and recovery... board has been worked on previously but after clearing a solder bridge everything appears to be as it should.

I'm getting the same from all 3 firmware options, I've let it run and the ECC errors continue. Anyone seen this before - have the nand degrade too far.

Just curious. Where was the solder bridge?

I have seen it when the loader is not compatible.

@franc - safe mode, I think this is one you've help check it has probe marks in all the right places.

@Tim - That's the only reference I could find about the error, having tried all 3 options available and all the other 2246xt's too, I'm at a loss. I'm a little behind on versions but I don't think ACE have added any new loaders for this O1120A , P0721A and Q0405A are the only ones I have listed at 240GB it's not a new drive and I've not had the problem with other ssd +'s based on the SM2246 .  This isn't one of those where it's been screwed up in an update is it?

On some SanDisk SSDs the safe mode shorting point corresponds to the NAND Ready/Busy* pin. ISTM that the common practice of permanently shorting this test point would be inappropriate for these SSDs.
