Talk:Service Connectors

This pad is used for the same purpose as on the PS3 System; a ZIF connector is preset on prototype versions.

• • it looks as if ribbon connectors could easily be soldered onto those pads, seeing as the ground pads are conducive of such.

• • • yep, that's precisely what they're for (take a look at https://twitter.com/MinaRalwasser/status/1035581527076294656/photo/1 for the ps3 service connector example)

• • • • But what can ultimately be achieved? Aren't there also some points where a USB TTL device could be soldered to?

• • • • • You can end up dumping the syscon flash (on ps4 and possibly vita and and ps3 as well) by glitching it

• • • • • • Dumping and modifying is a big jump though.

• • • • • • • You can also program it (the pinouts are known)

• • • • • • • • It would be nice to be able to modify it to skip any error checking (thus be able to boot even with hardware/software issues) - I think the syscon handles this...
