Playstation Vita PDEL-1XXX External<->InternalQA

Converting External to Internal+QAf:
 - (optional, highly recommended) install enso_ex
 - install psp2etoi, run it and dump udi blocks
 - put input_0FF48CED2B01_QAF_MGVIDEO_ADV_I.cfg as ux0:data/psp2etoi/input.cfg
 - run psp2etoi, apply configuration
 - backup contents of ux0:data/psp2etoi/ to a safe place
 - your console is now QA flagged for internal firmwares, which we will install
 - via neighbourhood, update with PSP2UPDAT_DEVTOOL_I_AIO_365_E2X5_TAI.NPUP
 	- if you dont have enso then install the NPUP with modoru

Temporarily disabling QAf/infinite activation:
 - run toggle_qaf.skprx with your favourite kernel exploit
 - the console will now skip QAf init, which fixes henkaku and some apps
 - to bring the qaf back you can either hard reboot or run toggle_qaf.skprx again

Converting Internal+QAf to External:
 - via neighbourhood, update with PSP2UPDAT_DEVTOOL_AIO_365_E2X5_TAI.NPUP
	- if you dont have enso then install the NPUP with modoru

Restoring old ConsoleID, OpenPSID, NVS and mgmt status:
 - rename ux0:data/psp2etoi/backup_input.cfg to input.cfg
 - rename all backup_nvs* files to nvs*
 - change input.cfg's INPUT field to "true"
 - change input.cfg's NVS_OP*_IOFILE fields to match the renamed nvs* files
 - run psp2etoi, press triangle to flash, reboot
 - you are exactly where you started!
