How to repair lite-on pad 101

[iateshaggy]

first you need to remove that wire, only expose just enough wire to solder to the board.  you want the wire to lay flat on the board when u solder it so pre shaping it is important.  basically, the same size and shape as the one in my pic is optimal.  after you think you are done soldering, take a multimeter and test all of your solder points to ground for continuity.  any current or past shorts can fry you whole drive beyond use.

Thanks Shaggy,

Trimmed it right down and had the same problem, so I decided to reflash.

Could not get past x52 status in Jungleflasher, got a feeling that pad 101 is stuffed (using Vampire) - do I need to make a homemade probe and bypass pad 101 somehow to read the firmware again?

[iateshaggy]

you can probe 122 alternatively.  you will need to leave the mra jumper on after flashing for the drive to work.

hi,i have some prob here.. ok i lost pads 101 and 122 ,thats ok i flashed drive like that ,just conected some wire to 101 pin straight from other side.then after all i cleaned all my soldering and put just this one bridge and that jump. and i know to fix 122 need to done some jumper from other side, well i did that many times i tryed and i tryebut thats what i dont understand..as i mesure voltage to pin 101 ,so without front fixing it should be zero ye..becouse it dont have any power itself, so why then he showing like 2.4v when i puting it on CK3 pro and giving power. its not getting any hot or nothing so its not short cut nowere,i checked that 3.2v with grn ,its giving 101k ohm. but its all showing that without all fixing,just with this jump what u see in pic..so were hes getting power then, why he showing allready 2.4v ,and drive itself not wroking on x360 ,even when i doing all fixing by your pic ,its going on xbox menu and showing that drive is reading and its all time reading...not opening tray,not closing,nothing. can somebody help.


and i was doing this fix for my board..

im just tired allready trying this 2 days...its brand new super elite x360 .never even used ,and i broked now dvdrom board..
yes and i lost CB24 i was trying to solder from that 101 pin and it went off..oops..so can it  work without it ? now i gave those 3.2v to pin 122 instead of 101,i made jump to there from C01 . but it makes no difference drive at all..i mean it must be now in stock mode. if i try to see it on jungle flasher is finds it and shows that dvdkey is verificited, should i try flash it again.but i have OFW and key and CFW files saved . if worse situation then will by new dvdrom sure. but what about fixing this one..and why when checking grn and 3.2v with voltmeter its showing those 101k ohms even without that jumper from C01 to 122.i only did that jumper what is in pic and that messure is already 101k ohm. ..should it like show that is bad ?..

look, I have the same problem with a liteon 93450c, always I get status 0x52. I tested the pin 101 and 122 and I get 1.8 volts (this is strange), because I tested a working pcb with cuts and show me 2.12 volts and I can get status 0x72, so I think what here is the problem I use many resistances (15, 18, 20, 22 ohms) and nothing.

Help Please,

and my english is bad realy bad, sorry for that.

[iateshaggy]

take a picture of the board.

[the-green]

take a picture & we can see!!!!

I dont have a cam right now, but I flashed many x360 with the mra method ( only two cuts), and I a have probe2 mod (I modified my probe1). I isolated the pin 101-122 and are fine. I tested around 5 pcb with the same method and the pin101-122 show me 2.12 volt, but the other pcb show me 1.8 volts and I cant get the status 0x72. Anyway when can get a cam I will upload the pics, thanks.

I really need some advise on repairing / cleaning up these traces.

CLEAN THE PCB AS IN "A" AREA (brush pen?)



seems like ur cuts aren't deep enough
seems also your hand is delicate as king kong's
use a ruler to stop ur hand while cutting

after the cuts check with MM green points and blue points
(to check with MM you must expose the copper in those points and obtain no continuity)
then go,ask someone to do the solder job for you.

Flashed my drive put in 360 drive does not respond. Done the pad101 repair and gave me 3 red ring undone pad 101 repair and rings went away.Fixed traces and xbox comes on but dvd drive won't do nothing dunno what to do. Flash took but 360 will not respond.
I have also flashed with wrong key and 360 would not come on till re flash with write key.When It does come on tv drive says opening but drive does nothing (motor won't spin eye won't move and eye doesn't come on.)
what should I do.

[iateshaggy]

sorry for giving yall all a blanket answer, but pretty much all of you have just used to much solder.  u want to use the least amount possible to bridge cuts.  if there is a large gap then use a small piece of wire to jump it.  refer to some of the pictures int he beginning of this thread and when you see one with a clean solder job, make your stuff look like that.  be sure to use a multimeter to confirm that you don't have shorts before powering your board again or suffer permanent damage.  if you still can't figure it out, send me a pm if you are in the us and we can make arrangements.

fixed my drive today.The drive was none responsive at any time but I could read and write all I wanted(done it like 20+ times thinking it was my flash anyway)It was a 8series board with a 9series sticker.Could not get the drive to respond so I solder a wire to the board in many places and this was the one that got it working don't know why it just did.This is a temp fix I will go back and solder smaller wire later just wanting to share my info.
And for ppl having trouble I found that my ck3 probe 2 was more responding when I powerd the drive half way open.I doesn't say any where to do that to a 8 or 9 series but it made mine read with less errors.
All of this is for education not responsible for what you try on your own drive.Try at your own risk!
Not sure how long drive will last but it was broken and this was the only thing that got it to work.

[iateshaggy]

that is way to much exposed wire.  you only want 2-3 millimeters of exposed wire when making these trace jumpers.

I know just a temp fix I put a 30 gauge wire on after the pic.

Hi All,

I got reference from other forum. Need you help.

I have liteon 93450C (Model : DG 16D2S-09C/Manufactured date :  Dec 2009).

I think I fired my DVD by upside down power cable (Not sure about it). But I saw smoke just after I plugged power cable. I was following MRA hack. I do not see any fired part in the PCB.

Here r the pictures for both the side

I used XBOX as power source for the DVD. I powered XBOX with DVD plugged in when I had trace cut. As it fired, I do not have key. After the DVD fired I repaired the trace cut and tried to power the DVD. With DVD powered ON, I get 3 flashing red light. Without DVD the XBOX works.

I have gone through the post. My understanding is that first I need to check  following.

Set the multimeter to 2M it should give you 0.100 - 0.105.

I am not expert fixing electric equipment. But one of my friend is expert. So I shall take his help to fix this. First I shall ask him to check the above. If any other steps are there let me know.

Just a question -- Do I need to provide power the PCB when I test the above.

If I need to provide power for the PCB, I guess following r the voltage details I need to provide ..

DVD power cable pin3 3,3V eject --> 0V closed.



Need your expert comment.

[iateshaggy]

those are both pics of the top, it doesn't look like you powered upside down, does the other side look like a bird $#!t solder on the pcb?

The trace cut at the bottom of your pic you can try unsoldering the cut and try in xbox again the three red ring should go away.Keep in mind it is not recommended for you to power the drive with a trace cut with the xbox itself.Recommended to buy a or make a external power source.(I heard it helps with reading keys out it sure helped me.) If that don't work then you can try my fix above.But if you get rid of the three red rings and the 360 comes on and works with drive in and your drive spins and laser works then it should play disc. If you lost your key if I can remember right your xbox will not display on the tv and the green light in the center will just flash.Same for putting in the wrong key.

Do I need to remove the soldering at the V cut and put it in XBOX? But If I do that then there will be no continuity. Will It work? Or I need to fix the V cut trace by proper soldering again. And after that I should check http://img833.imageshack.us/img833/4717/continuity.jpg to check continuity. After cutting the trace, I checked all the cuts with multimeter. And there was no continuity. But after the cut repair, I did not check.

I had very bad experience with CK3. I ordered from UK but it was not delivered to my address. I lost £24 GBP. So now I have to use home made prob and connectivity kit. I have found "Easy Probe2" by dream. Thanks to dream for the guide. I am going to use that.

I am not sure about the connectivity kit. Can I use following for the home made connectivity kit? If yes I think this is the details diagram link http://dream.pic.fi/kuvat/Xbox%20360/Home%20CK/Home%20CK%20LM317%20317T%20800x530.bmp/_medium.jpg





If I haven't fired the DVD, then what could be the cause of smoke?
