Chilly Willy has released an updated version of the 2.71 TA-082/86 downgrader by Dark_AleX, now only changing one idstorage key to allow the execution of 1.5 kernel. The main improvement is that your PSP will be free of any USBHost issues after downgrading.
If you have already downgraded your PSP and wish to recover the corrupted Idstorage keys, take a look at codes02's release over at lan.sh.
Discuss this release here in the official release thread.
