Getting some earlyprintk going for the iPod Nano7 after I managed to get USB working on U-Boot. Also figured enough of the LCD controller to draw on the screen. This is all thanks to previous work by q3k :)

Turns out you could access DiagShell in iPod Nano7 without any exploit by just sending the diag image after WTF. And memrw works so you can read/write anywhere 🙃

After working together with q3k, wInd3x now supports iPod Nano 7G by using S5Late. That makes decrypting and running custom binaries very straightforward. github.com/freemyipod/wInd3x

iPod shuffle 4 (S5L8443) is now also O B L I T E R A T E D by virtue of @__gsch's S5Late bug (Yes, the ROM is so similar to S5L8723, that they didn't even bother changing serial number string)

Since @primal0xF7 already shared his exploit for CVE-2017-12561 and I believe it’s useful to see different ways of exploiting the same vulnerability, here's my blog post about a 1922-Day for CVE-2017-12561. guas.ch/posts/1922-day-cve-2…
