There was supposedly a downgrader for 6.36, but I haven't seen it released.
I do believe the downgrader you are talking about is the 6.36 PRO HEN itself.
It has the ability to downgrade a PSP 6.36 to 6.35 by having the 6.35 version.txt in the Plugins folder in the root directory and then running the 6.35 update on the PSP.
This will 'downgrade' it to 6.35 firmware.
QUOTEActually, some people keep asking me about 6.36… so your advice for them would be, run this Hen to downgrade to 6.35, right ?
coldbird: Yup. 6.35 + version.txt fake + 6.35 update file. I didn’t test it myself, as the 6.36 hen was a quick recode from my mate here, but this should work. At least it did for him.
Virtuous Flame: Yes. Since 6.3x removed old decrypt support. It couldn’t go down to 5.xx kernel until Davee released his downgrader.
coldbird: Actually 6.20 was even blocked…But Davee added the missing decrypt keys. So up to 6.36 you can change between 6.20, 6.35 and 6.36 freely.
On 9g models however, you can only go down to 6.30, because of driver issues… So you see the downgrade to 6.20 is not possible on those units.
