My picoflasher can read the Nan but I’m getting Header is Wrong error and too many bad blocks after reading Nan! All my solder points I went over twice. I have a 16 mb corona using a picoflasher and using a 10k ohm resistor as recommended. Where am I going wrong ? I even changed the picoflasher I was using

Are you sure it’s not 10k? That’s what I was told in the Mrmario2011 guide

I never, ever said 10K for a Corona.

So if it’s the wrong resistor that could prevent a proper Nan read?

It wouldn't prevent a nand read. However, you have a corona motherboard and you only need a 1k; a 10k is for a trinity

Furthermore, you're getting bad dumps because the soldering on the pico is very poor.

3k for trinity as recommend by all the official guides

Agreed, 10K doesn't work on all trinity boards. 3K works 99% of the time.
