(adsbygoogle = window.adsbygoogle || []).push({}); Just giving ppl their dongle a purpose ont this higher FW, its same way as downgrading to 3.55 with a dongle and fsm, just use Rogeros 4.55 instead of 3.55 posted a video that its worked on a 4.66 slim from singapore, that one brought to me after another updated it.

Thought some might like this since this is alot easier and more reliable than updating then using the downgrading pup and jumping back and forth through errors.
Used BwE Nor validator 1.31 and hit yes on set to downgrade for 3.55 after checking the back up if its properly working with dumpstatistic. comment if you need any of the apps or files ill create a link.
no external hdd method.
Use a 2nd piggy hdd if you want to keep all your save data from the original firmware and just reinstall the original hdd and the fw after you exit fsm.

still need to get your internal motherboard memory using some memory copying device. do not expect a update like geohot above 3.55 thats game over earn cash and get the right tools and do it like every one else has to.
