Ugh...Don't start these threads, there's always some low firmware loyalist who say some random firmware is the best because they can't update.
As for my unbiased opinion, custom firmware 3.93 works the best for me. All my POPS work, all .iso and .cso's work, all plugins for 3.90 M33 work. Not to mention I think I'm helping someone else share the throne with DaX, which, I think anyway, DaX needs some competition to help him move faster and come up with creative features.
The people who say it isn't stable are liars. It has all the same bugs as M33, since it is a reverse-engineered M33 code. I just use it because the in-VSH recovery works for me.
i tried to upgrade to 3.90 M33-3, but the installer says i need 78% battery. I'm using only the AC adapter not the battery. I'm still waiting to buy another battery after making the pandora. I don't want to change the pandora back to normal. Can i do the update without the battery and with the AC adapter?
