My attempts to upload threads (on Threads) all have utterly failed with little to no explanation, so I am guessing Zuck won't see me there anytime soon.

Here comes the first PS VITA (devkit) to be unbricked! It turns its previous owner (a SIE engineer) bricked it flashing the wrong sysmem.skprx file in the active OS0 and never bothered to unbrick it. It's been fixed using SDBOOT and glitching.
Last but not least, let's not forget to thank @skgleba for his incredible work and patience and without whom none of this would have been possible!

Internal PDEL is now glitched and Firmware 4.00 SLSK have finally been depersonalized!
Thanks to @skgleba
for the help and patience he provided to help with this endeavor :)

For posterity, the first successful PS Vita glitch during a SD Boot sequence:
A retail first_loader dump for good measure.

PlayStation Vita Development Kits tower of doom.
