How to repair lite-on pad 101

[iateshaggy]

yours pretty much also needs the same, clean your soldering.  look at the clean pictures in the beginning of this thread and make your soldering look like that.

but what about the resistor, if i bypass it am i going to unprotect the circuit?

[Dream]

The resistance 3,3V to gnd is 68ohm. For r709 it is 131ohms and for r710 it is 98.7 ohms. After consulting with some of my friends we decided to bypass r709  and r710. As the resistance  can not be so high. So we short r709  and r710. Do you think it is safe?

More smoke if you do that.
r709/r710 is 10 kohm resistor and has nothing to do with MRA dump.

If all lines are fixed and resistance 3,3V to gnd is 68 ohms there is little hope.

Cut pan 101 and 122 install jump wire like in the picture then measure 3,3V to gnd.

iateshaggy, i tried to take pictures today of my board but no succes, they are blur.
but i guess the problem isnt on the bottom, is on top, i just found a burned resistor, the one in this image http://yfrog.com/11hiresdj

Can i bypass it, since it is a 0R resistor (R55 on board)?

Thanks

You do the same as heartshacker.
R55 is zero ohm resistor no need to fix it now.

How to tell if the MT is burned @ Game over.

Fix your board like i have drawn in picture.
IF the resistance is 95-110 Kohm drive is fine you can dump it.
IF there is no resistance 0 ohm @ open circuit r207 is burned fix it, new zero ohm resistor or solder bridge.

Burned Drives, Measure resistance 3,3V to GND if the resistance is low like 1 ohm - 20 ohm.

First cut Pink line 1 and measure resistance 3,3V to GND if the resistance goes high 95-110 Kohms the drive is burned game over!!

Second cut Blue line 2 and measure resistance 3,3V to GND if the resistance goes high 95-110 Kohms the drive is burned game over!!

guys, thanks a lot, a just managed to put my drive working again, and it is even playing games! now i need to dump just as a prevention for it, the problem now is that it is a little noisy, when he reads the game u listen the sound of it a little loud, is there anything that could have possibly damaged it? or is it normal? thanks

[xDP]

can you please help me out my dad was trying to install a LT Switch but my dad did something wrong :s



things i got:
lt switch
connectivity kit (tested and it works)
CK3 Probe v2

[iateshaggy]

u want me to recover the drive or tell u how to recover it?  you will need someone who can solder better than your dad.

Hi,

Could you please tell me what I would have to do to dump my drives firmware and then put it back to normal.

Here are some photos of the damage I have done:

For one of your fixes I tried removing the eproxy (glue stuff) to get to a point.
The one circled in pink is what fell off the board when trying to remove the glue.



And I also stuffed up these points (ones in pink):



Thanks in advance. I hope my drive can be fixed

[iateshaggy]

you don't need the resistor that fell off, but maybe you should consider letting me dump the board for you and just sending you a new board back.  you are only a screw up away from loosing your 360.

Hi,

Thanks for the reply.
Are you in the US?
I am in New Zealand and I have asked a lot of local modding company's if they can do a repair but they have all said no.
I am quite skilled at soldering, the damage to the points on the bottom of the board was because my mate tried to take off the LT switch v1.5 i installed.
I took off the resistor, so that's my bad.

Could you please tell me where I need to solder to get my drives firmware since the bottom of my board is no good anymore.

Thanks in advance.

try this one.  be sure to check for shorts.  all the area around the traces is ground and if the solder overlaps it, then you are shorted out.  the wire that connects by that resistor you broke off is the one you put the 22 ohm resistor on, i usually just probe the pin instead of soldering a switch into place.  do not power on the drive unless you are 100% sure there are no shorts, this can kill the drive beyond even dumping.  as is you will probably need a new pcb at the least.

Please, could you give me advice? I made the cuts, soldering job...but I accidentally grounded it and these two pads probably burned, i saw a smoke and now they look like this..:



According to tutorial I should fix it using the green scheme, right? And the resistor looks like it is fried, too...but it's only fuze, right? I can jump it with wire?



And this is my soldering job - corrected, not grounded anymore, tested by multimeter..:



Thank you for any advice. At least I would like to dump the key from it.

[iateshaggy]

use less solder and the exposed part of the wire only needs to be 2 millimeters long.  bend the end of the wire to the shape of the trace (not perpendicular).

[BloodyRutz]

Thank you a lot for your answer. Should I resolder all or just to listen to your advice from now on? And you agree with what I posted above, right? Jump the fuze resistor with wire and repair the trace using green fix? Sorry, I just want to be 100% sure before I start. Once again - thank you.

[iateshaggy]

you should resolder that hack job.  take a look at the pics of me and dreams work and make yours look like that.  also, if you are planning on doing a few of these, get a multimeter and a hobby knife.  remember, the less solder, the better.  you should also make an easy probe, most power supplies have a ground point and a 3.3 line to tap, then you only have to solder during the repair, not the dump.

Now you can see almost 900 posts. No bull$#!t always correct answers.
Problems are despairing why because hundred “stupid” questions zero bs.

Thanks to iateshaggy…

[BloodyRutz]

I just wanted to say thank you for this useful thread. I repaired the trace with burned pads by jumping it using wire according to green fix from Dream's picture and I resoldered it like iateshaggy said. My drive works perfect now, flashed and running. Thank you very much!

Soldering job..:


Fixed trace..:

Pads 101 and 122 are gone.
2 capacitors by chip are wiped out.  Are those needed? Do I need to do anything to fix them?

Where do you recommend I connect for the 101/122 to dump original L-O FW.
I realize I don't need the jumpers on both the top and bottom.
I was using Jungleflasher/MRA method.  Would you recommend using easy probe?

I apologize if this has already been covered.  Any help is greatly appreciated.
