A little update. Update pkg (the one on payload) doesn't work at all, doing an update. I receive an error when updating my JB2 using the original pkg uploaded days ago as pkg. Maybe it's me who didn't understood exactly what is posted on the wiki, but what i see is the analysis of.. the update?
Ok, maybe update contains the entire new firmware 2.1, but if it's just a partial update, you could never see any CFW with this payload at all. And if it's not working with a real JB2, over all, well.. Dunnno, let's hope
Without dongle, when you start your console, works normally, except managers. Video, music, and duplex PSN title (and bough one) works perfectly. Obviously you need to power on your console with your dongle, or will not be recognized (like the old JB dongle basically). If you remove the dongle, console brick, sadly true.
This means, if you have to downgrade or change firmware at all, you can manage everything without dongle. BEWARE: don't attemp to upgrade your console to CFW3.55-dongle with your dongle inserted, or this will badly brick your console, blue screen. Easy to fix, if you can use the old factory service method, luckily, but when back, you will lose all saves , rebuild filesystem or any other method available with your console, will be useless.
Use other methods if still interested to restore them, and use windows, because linux doesn't have any hope with wine using a tool. And as much i know, there isn't any HDD update available anywhere.
I truly love how positive you are on this scene
