@bloodien0se: Could you recap exactly what steps you took for me, please?
With a few extra questions: which FW version you started from, which PW3 variant that is (check the S/N wiki), and how much free space you had on your device?
I'll have to double-check, but I think error 2 is the fairly straightforward "something went wrong" one, which either means something stupid or something very bad hw-wise
.
EDIT: Yep, that's the basic "woopsie" error, which (I guess) means something really failed to flash at one point, which is never good in these circumstances...
I'll add to my initial questions: how well charged was it? But the updater should already take care of not trying anything on too low a charge...
