6.61 Chronoswitch Downgrader 6.1

Post by qwikrazor87 » Sat Jan 17, 2015 9:52 pm

This is a mod (hex edited) of the 6.60 Chronoswitch Downgrader by Davee/some1.
I only tested it on a 1k model, I couldn't downgrade to 6.60 from 6.61 (maybe corrupt updater), but I was able to downgrade to 5.00 from 6.61, 6.20+ might work, haven't tested it though.

Update:
Issue with 6.61 -> 6.60 should now be fixed, tested and working on a 1k.
Chronoswitch_6.0.zip

Update2:
Now supports PSP 11g (E-1000/Street) from 6.61 -> 6.60, thanks to nzgamer41 for testing.

Is there a reason it is unable to downgrade to 6.60?

And why Hexedit? Davee said it is open source :D

beats me D:
Edit:
Could just downgrade to 6.20+ then upgrade to 6.60 from there though.

Your downgrader does not work with the PSP E1000.

The PSP E1000 has only 3 firmwares: 6.50 (pre-installed), 6.60 (not supported by your downgrader) and the new 6.61.

I've just been on the UK PSN website to grab the 6.61 update to see if psardumper will dump it... Whilst browsing the Firmware Archive, I noticed they have removed 6.60 from the history... It just jumps from 6.39 straight to 6.61...

Same case on the german sony website. I guess the european sony page just swapped the 6.60 in favor of the 6.61.
