I can't upload the files here cos the files are copyrighted use Dark_Alex's PSARdump.

After you download it, follow on with Step 5. I'm not sure will those works since there's signature protection in 2.80+, report it to me if it works

This method is safe to use since it runs on memorystick. No worries on bricking ur PSP

---------------------------------------------
Instructions

Step 1
Download Dark_Alex's psar dump mod with sigcheck from http://www.dark-alex.org/psardumpmodwithsigcheck.rar
Unrar and copy psardumpmod and psardumpmod% to /PSP/GAME folder


Step 2
Use PBP Unpacker to extract DATA.PSAR from 2.80/2.81 firmware EBOOT.PBP and copy the DATA.PSAR to the root of your mem stick.


Step 3
Run psardumpmod. In the menu screen press the SQUARE button and it'll dump 2.80/2.81 firmware and decrypt all the files to your ms. All the files will be inside F0 folder.

Step 4
Goto F0 folder and rename memlmd.prx, mscm.prx, mesg_led.prx, registry.prx, utility.prx and impose.prx files to memlmd_280.prx, mscm_280.prx, mesg_led_280.prx, registry_280.prx, utility_280.prx and impose_280.prx and copy them from F0/kd to dh/271/flash0/kd folder of your mem stick.

Step 5
Open pspbtcnf_game.txt file and edit.
/kd/memlmd.prx to /kd/memlmd_280.prx
/kd/mscm to /kd/mscm_280.prx
