***** 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... | |||

Pad Info[edit source]
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...
