when FWtoolbox 4.5 was released it allowed in-circuit flashing of the 78 chip, but NOT the 79FL/FK chips..they have a physically locked bit in their firmware registry that disables the ability to put the drive in ModeB.
This is the same thing done in satellite TV boxes to protect their firmware..but that was easy to get around using an external VID modification that blasts the chip with higher 12DC voltage to unlock that bit/register...these bits stay locked at 5 volts typically and unlock when its raised...but this is a more complicated issue with the Hitachi 79 drives.
thus Maximus invented the 79Passkey that acts as bridge to skip over that locked security bit and allow FWtoolBox to read/flash the 79FL/Fk's just like a regular "unlocked" 78 drive...it performs the same function as the VID mod. described above.
but these 79PASSKEYS are very poorly designed IMHO especially the ribbon cable option..the clearance of the bridge was NOT well thougth out by Maximus...most of the people who have bought them have damaged their DVD trying to install them because the bridge wont seat properly or flat on the board and it damages surrounded IC's..its EXTREMELY difficult surface mounted soldering in a poorly designed and too tight a package...not easy even for experts to install...
so the 79PASSKEY is an expensive and impractical option in every sense of the word..plus its going to eventually fail because its so poorly seated on the mother board to begin with..that eventually I can see several of its tiny solder leads losing electrical conductivty in these very hot 360 consoles...and if that happens it will corrupt the firmware and eventualy brick the Hitach Drive...possibly making it impossible to re-flahsed again...
trust me guys you do NOT want that thing installed in your Hitachi 79FL/FK mother board...its not a smart idea.
what is the smarter way to flash a 79FL/FK?
send it out to an expert who removes the hitachi 79Fl/FK DVD chip and externally dumps to obtain your 79FL key and then re-flashes it with latest hacked ixterem v1.4 firmware...using an eeprom programmer like the Willem.
this is one of the "official" experts that repairs bricked Hitachi/Samsung drives and dumps the 79FL keys externally and re-solders back onto the motheboard..I think he charges $40 for the whole service., plus $10 shipping and qith extremely fast turn around.
why is this better than 79 Passkey?
safer and costs about the same anyway as that Passkey nonsense.
because once he dumps the 79FL/FK and reinstalls the orginal chip flashed with 78 firmware..thus your 79FL is now a hardcoded 78 drive....and the 78 drives are fully recognized by FWtoolbox4.5 under Windows XP and will allow this former 79 drive to be flashed in modeB easily just like anyother 78 drive.
just NEVER NEVER NEVER flashback the original 79FL/FK firmware bacause it has that security BIT still hardcoded and locked in its firmware and you will have to remove the Hitachi chip all over again or dump it with 79Passkey all over again if you want to play backups.
the ixtereme software v1.4 should still enable modeB moving forward in these 79 drives flashed backwards into 78 drives.....using either that Slax2.1 CD or just startup the Hitachi with the TRAY already pulled out and fully open.
I suggets this guy he does fast and great work and is recommended by Maximus and in fact advertises in that banner that loads when you startup his FWtoolBox v4..5:
Location: Yakima, WA 98908
Aim: Grim1873
Email/MSN:[email protected]its much better to send out the 79FL's and get them externally dumped and reflashed with 78 ixtreme v1.4 firmware...you will regret that 79passkey if you buy it...its more trouble than its worth..plus its very unreliable from all the reports I have read...too inconsistant...and eventually it might evenl unseat itself and brick the Hitachi or serioulsy corrupts its firmware...I can see that easily happening.
p.s.
my 79FL drive key was at location: 4E10 and my chip was removed, dumped and reflashed externally and then solder back onto the Hitachi board...cleaner and now its just like any other 78 drive...I can re-flash in windows any time I want since its NO LONGER permantly locked...
p.s.s.
the 79Fl/FK chip is also been encased in hard epoxy by MS...so that has to be phsically melted off with a micro torchh before you can install the 79Passkey..that's another very delicate process and if done wrong can fry your Hiatchi chip...
