i made my own probe for my liteon using this tutorial (http://xbox-experts.com/e/tutorial.php?n=flashyourliteonf) and every time i try to extract my key using JF, it says serial data is bad. I used a multimeter to test if my design was working, and got 5.62V from the probe to the RX on pin 2 of my serial port. I also used a MPS222a transistor, looked up the data sheet and was the same design as the PN2222.

First i opened the tray, and then unplugged it while it was closing, and then hooked it up again. Tried it a couple times at different lengths and nothing worked. Then i tried opening it, unplugging it, pushing it back halfway and then plugging it back in, same results, bad serial data.

I tried COM1, but it always hangs and JF stops responding, and COM2 is bad serial data.
Anyone know what i am doing wrong?

have you followed the tutorial in regard to portio drivers and via card if you have one
are you selecting right port for your sata cable to your drive
you are not giving much info

portio drivers are installed, i have a via 6421 card with the drivers removed. I am selecting the right port as jungle flasher reads the liteon drive. is there any other information that you need? the card works perfectly as i have modded many other drives with it (hitachi, samsung and benq)

are u getting good contact with the probe

yes im using a needle so it fits in the whole, im not sure why it isnt working, i bought some pn2222 transistors today, ill try with those, but i dont think they are the problem

you might have overheated the transistor, when i got serial data bad i switched transistor and made a whole new tool and then it worked.

i used a multimeter and it reads 5.62V from the probe to the RX connection on pin 2 of the serial port, so i doubt the transistor is overheated

you are getting bad serial data when using jf , ok, thats nothing to do with portio drivers. incorrect sata card ports, its a pure serial connection nothing else, unless using usb to serial conversion of course,so its got to be either your serial port or your probe/adaptor,use hyperterminal to determine your serial port is ok, by shorting out pins 2 and 3 then make new connection , select 9600 speed , data bits 8 ,parity none, stop bits 1, flow control none, whatever you type on the keyboard should be repeated on the screen, then you know your serial port is ok and you know what number your com port is,thats as far as I can help really, because I use a max3232, built 3 altogether, me and 2 pals with no issues,I am not totally convinced with these transistor based dumpers as they are not using true ttl levels its all dependant of your tolerance level of your com port,so for the cost of a max3232/232 and a few caps , I dont think its worth risking your xbox.I am not sure how you would loopback your probe to test, my probes are two legged affairs( the early version) . I would connect my two probes together then use hyperterminal to prove the rs3232/232 to ttl adaptor was working.I dont think using a multimeter is a good enough test to prove your adaptor/ probe.

i used hyperterminal and did the loopback test, which wasnt passing so i borrowed a usb to serial adapter from a friend, and it passed the loopback test. It still is giving me a bad serial warning, so im gonna remake my probe once again hopefully itll work this time

thanks for all the help guys, i finally got it working, put a brand new pn2222 transistor and finally got my key. i ended up having to use a usb to serial adapter, something is wrong with my com ports, i only have 1 yet 2 show up, im guessing 1 is my lpt port and my computer is just confused.
