Liteon 74850 and CK3 Probe – Serial Data Bad NO GREEN LED Explained

Some of you are posting that you get no green LED when connecting the CK3 probe to R707 on a Liteon 74850 drive.

The answer is simple – chances are you have already previously flashed your drive with iXtreme firmware. Once that has happened then is no serial connection going to R707 (a serial connection provides 3.3v) therefore no LED  (Serial is turned OFF on 83/93 based fw – and iXtreme LT is based on 93 fw).

So when you FIRST use the CK3 Probe on a stock drive – always make sure you save your OFW / Dummy.bin / DVD Key – then you will be able to upgrade your drive without the need for the Probe in future.

To prove that your CK3 Probe is not faulty – simply return the drive to its Stock 74850 fw and you will see that the green LED works again as there is now a serial connection going to R707.

Note: Any keys that you have dumped are stored in the Jungle Flasher Key Database so don't panic if you think you lost your key !

You can also dump your pre-flashed fw info using the "Dummy from iXtreme" option in Jungle Flasher.
