| + | [title] Testing the board |
|---|---|
| + | [* black] At this point I recommend testing the area around the sim card reader on the motherboard. If you have a microscope, after proper cleaning it should be easy to check for bad pads, lost components, anything out of the ordinary. |
| + | [* black] Also perform a check with multimeter, using the continuity test mode, to see if the pads actually lead to where they should. |
| + | [* black] There should be no continuity between any two pads, except for the two ground pads (marked black in the picture). I jotted down a few resistance values for resistances between the pads, in case somebody needs to know them (they are approximates, apparently there is variance to this)- if you need to know these, send me a message. |
