Dark_AleX has just updated his Booster that allows PSP users to use fw1.5 and fw2.71 on a single PSP.">Devhook launcher port to support 2.71 flashing. Clueless what it means? Stick with us here, we'll tell you what it does.

People might remember Booster's last version of Devhook before the whole mess. That version allowed people to flash a part of the firmware dump to the flash to speed up the loading of Devhooked firmware. While this was a bit dangerous, some people still tried it just to save those few extra seconds.

The previous version of the Devhook launcher did not support this because it was incompatible. It now seems that Dark_AleX has figured out how to accomplish the 2.71 devhook flash loading.

Here's what's in his readme:

"Note: i've hacked msreboot.bin in this version to have support of direct flash in 2.71.
However you cannot have direct flash 2.71 and 2.71 emulation at the same time (the emulation
of the rest of firmwares is not affected by this).

If for some reason you prefer emulate 2.71 in your 2.71 instead of the direct flash thing, just
go to the folder dh/kd in the root, and rename msreboot.bin to something else, and msreboot_original.bin
to msreboot.bin"
