How to repair lite-on pad 101

[Dream]

Wheres a good ground pin to measure to?

Solder mra 3,3V jumper and measure.

Thanks. It is almost short circuit. Your chip is burned there where sata lines go... Bad

Think Boxxdr can get the key off it for me?  lol.

Well I spoke to Boxxdr.  I have to go see him on Monday for some reball work so I'm going to drop off the board then and see what he can do.  lol.  He didn't seem to optimistic but said he'll try and see what he can do.  Thanks for your help dream.

i signed up just to get your help dream

anyways, i think i screwed up. i got my dump properly but when soldering everything back in i think i dug in too deep and burnt the hell out of my trace/board.
this is how mine goes: http://i41.tinypic.com/166fb4y.png, the erased part is where i have my trace screwed up big time including the one pin in the middle of the trace (it's completely wiped out). at the bottom where there's a cut when you're flashing, i have it reconnected.

i went through the thread and noticed a few different ways, what would you suggest i do? thanks

(btw my drive is a 93459c)

is there a reason u like to jump on the resistor side the board?  easier?

Less scratching... You should try it some time.

i just use a vampire + xtractor pro.  i was noticing though that the pro has a grd pad and a 3.3 pad that one could just solder wire and the resistor to, maybe glue to an old credit card and bam, home made vampire.  next time i'm in a pinch though and vampire won't work for what ever reason (has happened b4), i will give it a try.

You still have to repair the cut´s, so you have to solder.
If you can repair the cut´s you can also install the 3,3V jumper. (tekes 30 sec to install it)

So use 3,3v jumper, map pin + resistor works every time. (easy to make)

hey dream, i already have the dump and i'm only trying to resolder everything. the problem is that the middle pin at the top is all f***ed up now and i was wondering if there was a way around connecting it and just connect something else to get it working. i can resolder the top trace but it doesn't work.

here's what i mean: the red part shows my problem. it's all messed up and you can't even see the pin anymore

[Dream]

tazmania i am sorry wrong picture.

[tazmania]

im sorry what? btw the bottom pin is resoldered properly so thats not a concern.

[Dream]

This is your fix...

[tazmania]

ok can i do this?

in black:

so i connect the top two pins (which are circled) with a wire. then connect a wire from the black place to the bottom?

would that work?

[Dream]

Yes

[tazmania]

alright i soldered everything but now it won't power on. im using the ck3 to power it on but it won't even turn on when i turn the switch on. when i disconnect the drive the ck3 turns on however

[tazmania]

after fiddling around with it for a bit i found the problem (bt don't know what to do).



so the red lines are connected. if i leave the right side of the black line unconnected it powers on but isn't detected in jungleflasher so that i can flash it (remember i already dumped it so i just need to load it). anyways, when i connect the right side of the black line, everything just dies off. any help? i'm so close yet so far

(btw ignore the red circle around the red line
