The Noobz have released their 2.80 downgrader, an improved version of Dark_AleX’s TA-082 2.71 downgrader. HEN-D can now be run on 2.80 as well if you don’t want to take the risk of downgrading.

Here are the advantages:

• safety - this downgrader has plenty of safety checks in place to try to avoid accidental bricks (but read the warning below)
• convenience - because this downgrader works with an official firmware EBOOT.PBP file, and includes the TA-082 idstorage changer and HEN files, you don’t need any other files (except for a v1.5 update EBOOT) to perform the downgrade. No more finding a v1.5 owner to get dumpfiles!
• latest TA-082/086 support - the bundled TA-082 registry fixer includes the latest fixes to make sure that USBHost support won’t be messed up.

WARNING - Like any downgrader, there is always a risk of bricking your PSP. We have done our very best to make this as safe as possible, but by using this program, you accept all responsibility for any problem that may occur. ALWAYS READ ALL THE INSTRUCTIONS CAREFULLY BEFORE USE.

ALSO NOTE: This has only been tested with the v1.5 EBOOT. Other EBOOTs may fail, or brick your PSP.
