83850c Lite-on Flash Help
« on: November 06, 2009, 03:58:00 AM »

I have spent at least 12 hours researching on how to flash this drive. I managed to flash it by using the ck3 xecuter pro connectivity kit on my VT4261 via card (with drivers uninstalled as instructed), used the latest jungle flasher (1.6.8) and first clicked LO83.info to dump the source. Everything went smooth and I double checked my drive key using other tools and saw the hidden message you are suppose to see (the key is not all 0's, C's or does not start with 1, it looks legit and perfect). Anyways I had everything else dumped and jungle flasher did not complain, so then I did the erase and loaded up the newest hacked firmware for the 83850c drive and let it flash after the erase, flashing all 4 banks and verifying them was all successfully. Did a outro/ata reset at end and then powered off drive. Plug back in drive to my 360 properly and the drive is acting REAL funky. First off the power led on the 360 is blinking non stop and the drive continiously ejects, even when I power off the 360 it will eject before shutdown. I am not sure what is causing this abnormal behavior, can anyone tell me what I can do, I have tried replacing all my cables, flashing the drive with the tray either half open, closed, or open with all same results. Please I need a way to fix this, I need to know what is the reason it is doing this.

P.S. I can't find an option anywhere in Jungle Flasher to restore a lite-on drive, is this possible? Only reason I am asking because I want to flash the original dummy.bin and see if the same symptons are happening or not, that would tell me right away if it's a bad dump or something with the flashing/hacked firmware. Other note is when I load the firmware, and spoof it, it says key is @ N/A on the target, not source, not sure if that's a issue or not. If it is, how do I make it the same as the source?

once you erase your original firmware from the liteon you can never go back.

I think your first mistake was selecting the hacked firmware manually. Once Jungle Flasher dumped the drive it should have asked if you wanted to auto load the hacked firmware and spoof it. By manually doing it you may have selected the wrong firmware to flash to your drive.

You BETTER make sure you don't loose those dump files or you will be needing a new console.


The good thing is you cant really brick a Liteon. You will have to load the dummy.bin and your source firmware and have Jungle Flasher auto select and create the proper hacked firmware for your drive. Once this is done you will need to boot into dos and use l-o-eras and dosflash to recover and flash the drive with the proper firmware.

That is not entirely true. I have been able to restore some drives after erasing, namely my lite on DVD RW drive for my PC after erasing it. I have done it with one other Lite On drive. You have to boot in to DOS and put the info on to your bootable media you used to get in to DOS. Don't ask me specifically how to do it, I looked up a lot of different lite on utilities and had to use some DOS Flash utility. Don't give up hope, if you have an adequate amount of PC knowledge then you should be able to come out of it.



but that's just my opinion, I could probably do it again if I NEEDED to, but I don't think that issue will come up again.

totally different thing dvd writers or roms dont need matched keys to your 360s main board and flashing a incorrect  one to a none jtagable 360 will make it useless
the thing you did was recover a bad flash which if you flashed over the main flash part which only some dos programs let you do would also render that drive useless
there are multitude of hacked files for every dvd drive ever made which make it so it is region free or allow you to update to better version of fw which allows drive to cope with new media
if you could recover a bricked 360 lite on in dos with incorrect key data which atm you cant then im sure myself and everyone here would want to know how to do that ..

Hi

I have the same problem as the original poster.

A July 83850C refuses to leave vendor mode - or that is how it appears.

The drive ejects/closes constantly since extracting the Liteon dummy file, then attempting to exit JungleFlashers vendor mode by selecting Outro/Reset.

I also tried spoofing a Benq drive with the saved Liteon dummy.bin and the Benq 1.6.bin, but same happens - drive keeps ejecting.

Have also tried using DosFlash, but it made no difference.

When I started this (few weeks ago) there was no mention of the new drive being an issue.

Even so, like ExcitedGuy, I did manage to extract the key ok - it matches exactly and looks fine, but other new 83850c 360s are being reported as unable to dump the key at all.

I haven't a clue what to do next, but have been attempting to fix this on and off for a few weeks.

I posted on another forum, but no luck as yet.

ExcitedGuy, if you have any luck let me know and I will do the same!

I am still trying to fix my ejecting 360, and have come across posts on this forum suggesting to unplug the laser ribbon cable, before flashing.

I didn't know this was recommended, and it isn't mentioned in the JungleFlasher tutorial, but I wondered if somehow the flashing procedure has messed up the laser?

As I said before, this constant ejecting is happening on 2 360 drives - the original Liteon 83850C, July 2009, and a Benq I attempted to spoof using the dumped Liteon dummy.bin.

Is it worth purchasing another drive, then attempting the flash with the laser unplugged?

Or is this unlikely to be the cause of the drives ejecting?

Advice appreciated!
