WARNING! Use at your own risk. There is little point updating to 6.61 atm so risking the downgrade should only be undertaken on consoles that can be affected by a Pandora battery and MMS.
So following the release of OFW 6.61 and the subsequent testing by various protagonists in the psp ‘scene’ (qwikrazor87, The_Zett, SMOKE587 etc) there have been some releases. Qwikrazor87 has ported/hexedited Davee & some1’s Chronoswich Downgrader for use with OFW 6.61. Currently it has been tested on some consoles but not all as yet. Also there is a bug that “corrupts” a 6.60 updater when attempting to use it which renders it useless on the E1000 (Street) version (not that downgrading to 6.50 [min version] serves any purpose anyway). As it stands one can now downgrade from 6.61 to 6.20/5.03/5.00 (just sampling the significant firmwares).
Again use at your own risk!
