OMG you guys don't know how many countless hours I spent trying to recover my password on my brand new radio. I didn't even get to tryout my new component speaker system that I just installed before the HU started crying at me stranger danger - you don't know my password!
I tried hours of manual entries, used 7 different usb thumbdrives, different brands, all under 4gbs, 4 different extractors for crap Testmode, testmode_a, Supertestmode, codihack, password removal script, goldenapple, golden_apples__eggs, PioneerAVH4000FactoryService, 400
