Sup everyone ok been tryna flash this drive over n over with iprep10 and cant get it to read the key keep getting error invalid key i dnt know anything bout these new drives can someone fill me in on whats dif. bout these drive n if there is a dif. way of flashing these then other lite-on drives....thanx in advance

Give us the steps that your doing up to the point it tells you invalid key. There is more than one thing that can cause that. With the 7xxx series, you have to use a probe to get the key, or solder r707. That being the case, make sure you have specified the correct com port for the serial communication. Also, check to make sure the correct sata port is being used and is correctly specified in iprep as well.

well i get iprep loaded up turn on my ck3 eject tray turn off ck3 close tray half way turn ck3 back on n put probe in r707 hit enter iprep trys to read key but they all say invalid...im bout 97% sure my set up is right considering i use that pc to falsh drives n havnt touched anything since my last flash.. im wondering if maybe getting the tray in the right position may b a lil trickier wit these then original lite-ons ????

[sadalius]

Yeah, tray position if not right will keep the drive from going into vendor mode but it sounds more like a communication problem between the computer and the drive to me. Has this drive been flashed before?

I am prob going to get some S@#$ for this...... but you might want to try a different version of JF as I use version .26 for Lite-on's it does not have all of the safeguards in place though make sure you back up the key.

Also I don't go to 75% on the tray I am more like 50%.

Drives never been flashed before its new....if i use JF will there b anything that has to b done dif. then doing any ohter lite-on with JF??

Nope, same as all other 7 series lite-on's

ok thanx ill try JF see what happens i thought these drives had to b handled a lil dif. then other lite-ons

[HaGGardSmurf]

Well the 74850C are the first lite-on's released.

They have 2 F/W revisions A0A1 and A0A2 both are handled the same way. In the stock A0A2 FW, it identifies itself as A0A1.

The lite-on's that are handled differently are the 8 series (ie: Lite-on 8xxxxx)

well guys its flashed thanx for the quick replys..i ended up using older version of JF n of course it locked up so i had to use the recovery method but hey whatever wrks...but sadalius was right bout me having communication problems when i was trying to use iprep10 my bro decided to put music on his ipod n unpluged the usb for the ck3 then plugged it back in a dif spot then i origanaly had it so when i was makeing my boot disc for iprep i kept using the wrong COM i figured that out when i was using JF but was so frustrated by that point that i just went on to use JF but im sure iprep10 wld of wrked jus fine MY BAD GUYS next time ill make sure to check my set up bfore i post lol
