Hey everyone! Got myX3 the other day. I've insatlled many X2.6's before- this is my first X3.
I installed it in a 1.4, installtion went brilliant, turned it on, flashed it, perfect!
I then moved it onto a different board, I got a new Crystal 1.6 (it may be a 1.6b, i dont remember if the cable was brown or not, as i switched some cases for various reasons) I had used a 2.6 on this board previously, so i knew the rebuild was perfect. I put the X3 in, install went well. turned it on, my 5v LED came on, but not my 3.3v LED- i looked up on the forums, and found that i needed to move my 9solder point to the 15 point (alternative 3.3v) this solved my problem.
The chip worked fine , turned it on, flashed- perfect. However, as the night went on, the chip started acting strange. first of all it refused to play homebrew- then, at random stages, the chip would decide its self when to turn on /off when turning the console on. And when i manage to get the chip on, all bios banks FRAG the system.
I can load the backup bios (FlashBIOS 3.0.0) it comes up- says its Read Only. when i try to flash with the latest bios, it just wont flash. it comes up with
'Unknown Flash! Halting'

I really am stuck. I've desoldered all my connections, and resoldered them- no help.
Many thanks for your help people :)

p.s. these forums rock

Just adding whats happend now.
I've put my X3 into a 1.4 Xbox. It still frags on all banks. i attempt to flash via network, and it acts like the chip is flash protected. i try to flash via CD and it says the BIOS is not found (even though i've flashed via CD before)
'No Bios Update Found... Halting'
not sure how to proceed! please help someone :)
I got my Chip from MrModChips.com
Thanks

I've solved the problem. In case anyone was having the same problem. the hard drive couldnt be read by the xbox- i simply put in a different hard drive, and it flashed perfectly.

how to restore Liteon 74850 back to stock??

Can someone be so kind as to give me the correct steps with Jungleflasher 1.70 on restoring the drive back to stock?? Trying to figure out what to use as source and target, I'm guessing my dummy.bin as source and then the 74850 Orig firmware from the LT folder as target right?? Then you spoof it correct?
