Well, since this section of the forum is called "Sony Programming and Development" I thought posting about this here was appropriate, I'll cut the chase. I have spent the last couple of weeks with my DTP-T1000 dumping and documenting as much as I could regarding its boot process; some of which has now been made readily available here: https://www.pspdevwiki.com/wiki/PRE-IPL Nevertheless I thought it wouldn't be appropriate to not give others the opportunity of dumping their own devkit kbooti code, therefore I wrote a dumper and made it available on github: https://github.com/mathieulh/DTP-T1000-Pre-IPL-dumper I thought PSP Development tool users would have appreciated the gesture, no matter how late I got to the party. Of course this dumper works and has been properly tested on my own unit, you will need root access to your devtool's CP to use it; check this page to know more if you haven't already: http://www.psdevwiki.com/ps3/Communication_Processor Needless to say I am actively looking for any pre 1.00 sdks and boot files as well as anything in between 1.50 and 2.00 and 2.71 to 3.50. If you have such files at your disposal, free free to contact me. As to the DTP-T1000 I will keep digging to hopefully uncover more of its secrets.
