i have successfully unlocked a xp1800 and a xp1900, i consulted many of the guides and to be honest the advice and methods used are verging on the stupid and the impossible
now i played around with several methods until i perfected the technique, our first challenge is to fill the laser cut trenches, i firstly tried enamal piant as i didnt fany superglue this worked fine until i tried putting conductive paint on and it didnt bond..!!
Unlocking an xp in 5 mins (in practice about 3 hours)
1.place chip pins down on foam or rubber.
2, using a bright light iluminate the area
3, i recommend a magnified eyepice your local hardware shop will have them for a few pounds i use a 7 and a 10 magnification
4, place two pieces of scotch tape along the contact sideof the level 1 bridges, align the edge of the tape with the pits(not thecontatcs) as the glue will seep
5 put a small amount of superglue on the end of a needle a carefully fill the pits
6, sooner rather than later remove the tape
7, you may wish to clean of the contacts if your superglue has seeped, use a toothpick, tissue paper and a small amount of acetate(nail polish remover)
do not by any means use a sharp instrument as toms hardware advise as you will scratch of the top coating of the chip and reveal bare copper, it is only a very thin layer, be warned
8, no the next step is depending on what unlocking solution you are using. i personally opted for the chemtronics contact pen, which is recommendedby oc ctores in the uk, the only problem is the stuff may be fine for applying big traces on pcb yet is crap for unlocking xps, i popped along to their site www,chemtronics.com
and was able to ascertain that the solution setting time was dependant on temprature as well as air contact, so in the freezer she went.
The major problem is the conductive ink is quite gloopy and thick and we really want to have thin straight line over the l1 contacts.
Now you can float the ink in a pool off acetate to delay the setting i had varying sucess with this first time it worked fine then i messed up the last contact AND HAD TO RESTART and couldnt repeat it.
9, once you have the ink at the rquired consistency aply with the tip of a pin head carefully
Please note, none of us will get this right first time, the advantages using this method is that the superglue can be wiped off with acetate as can the conductive pen, rather like a whiteboard until you get it right, what i wouldnt advise is rushing be 100% sure it right before you power the chip up, cross those briges laterally and you can fry your ram and cpus
apologies for dropped letters my cordless keyboard needs new batteries.
