so just make that part below ?..that connects to the same power supply in the pc that the conectivity kit is hooked up to ?...only other problem is i have destroyed both pad 101 and 122  ..... sorry if i ask stupid questions |

Probe it. I can see it from your picture. |

I can assure you that the flat circular copper was removed from the board, however, i believe you may be referring to the copper WITHIN the hole itself that may still reside on the inner wall of the hole ?..if so...i should go ahead with probe ?...im not sure if i need to make any other alterations by adding this probe..ie removing the switch and wires attached to it and the other ends but leave in place the trace fixes...i dig my hole deeper still  My resistor is correct ? red red black gold brown |

Your attention to detail is really helpful....that resistor colour code is confusing...is my resistor incorrect then..i ordered 22ohm ones and a website showed that banding to be 22ohm...im going to try this now...

Measure it with multimeter set it 200... I won’t give you the answer, figure it out and learn something.

Dream im really not against learning, in fact i love it....and i have learnt a great deal over the past two days...i measured it...it IS 22OHM as the reading is 22.0 bang on, i looked at the colour coding and its is interesting to see how the meter inteprets the value, ie, where the decimal point is...just to give you a little faith in me, i pulled some random resistors from a hobby set and put the meter to them, i noticed that i had to move the range on the meter to get them to read, i read the meter and then checked the values with a colour chart...i have learnt something else today...the reason i might seem a little impatient to get this going is that it is not mine and i really wish i had not offered to do it as i do not seem to be having much luck with it and they are asking me how its going.
The drive reads but i keep getting BSOD, if i dont get BSOD then it just carrys on and then say device intro failed...im not sure that probe is making contact..but the same thing always happens...i hit device, i get a prompt box asking my for yes/no, i power off drive, probe, press yes, power on..it either locks up or times out....

You can use 2*30 ohm resistors to make 15 ohm resistor. Ok you think that there is no conection? I am going to post info how you can test it.  |

partial success !!! with pad 122...i spun the pin around in the hole and it seemed to open it up slighlty..i think there must have been gunk in there...still, it read bank 0,1,2,3 then offered me to save...but before i could i got the BSOD...i will try again

Intro-->MKT bla bla bla YES-->power off-->Probe-->Power on-->status x72-->probe off-->read. |

Yes...was reading your post, three different methods..the second one i can get a read but the pc keeps locking up and crashing...i never had this problem before with doing liteons before...strange that it starts doing it with this drive...maybe i should try my nvidia controller

Pad connection tester. Power the drive and probe pad101 or pad122 hole. If led lights the connection is good remove led and dump it with easy probe method Page 4 reply 66. No light no connection or led is installed wrong way. (Led long leg is + short is -) If you measure voltage DC with multimeter it is aroud 2,5V if it is 3,3V the cuts are bad.      |

Dream...i done it..with your help and some perseverence..i think it came down to power cycle timing to get the read done, i am going to make that led probe as well for future use... Now if i encounter this drive again, is it a case of just isolating pad 101 and 122 and using the probe ?...i have the jump wires on becasue i screwed the pads correct ? Again..correct me if i am wrong..now the drive is flashed, i DONT remove the jump wires i have on as they are to reconnect the pads..and in which case i do not need to try to repair the cuts i made ?...so my board should look like this before i replace it on the drive...  and...  Thank you so much for your patience and tutoring, i HAVE learnt a great deal and you have further inspired me to learn more about what it is i am doing and understand rather than just doing it |

Install jumper wire, R207 0 ohm resistor to pin101 capacitor. (this will fix your broken pads 101/122) The other jump wire in the pic is same as your upper jumper --> Jumpwire: R207 0 ohm resistor to C03. Or just do it like in the picture. Last measure 3,3V to GND.  |

loady,
I am using awg30 wire and flux. Your work is normal beginners soldering.

i was using rosin flux to.... the wires what i found in a hobby set...i gotta say though, i am $#!t hot at lifting and replacing TSOP though...i am hoping to get another one of these to do ..this time i will make my trace cuts a little more refined and use your probe...i will show you my probe when i have done it...i think you will be pleased with it

RE your pad connection tester...why cant the led remian for dumping ?..i was planning to house the whole thing into a pen..i suppose i could build in a small switch ?
PS...box is working fine and is flashed !!
