that´s why cheap UEM´s are not working - GSM-Forum

John_Doe · 01-16-2004, 23:05

while playing with some UEM´s i discovered that a lot of people have been cheated with dummy-chips.
i bought also some bigger quantity and was wondering why they are not working

look here:

original UEM, you can see the die, looking like metall

dummy "UEM", NOTHING inside

it´s possible to check with multimeter if UEM is ok or dummy, will post it here after making some more tests...

regards,

btw, i have still stock of those dummy´s, if anybody interested then just let me know

i´ll make good price

An X-ray machine should help to see inside chip, but it's expensive

leosedf · 01-18-2004, 01:54

Go to the nearest hospital and ask for an x-ray and hold the chip mear you. LOL cheaper method :P

Luciano · 01-18-2004, 05:36

Checking with multimeter should be enough, like we are checking PA's...

leosedf · 01-18-2004, 14:56

@All

Hehe fake UEM's are not the only thing you risk getting

Under here you'll see some nice PA's that I bought like a year ago or so, I keept them since it was funny

hehe

The PA seen from topside looks like a normal one right ??

Hehe And now from the underside of the PA, looks a bit suspeciuos no ??

And now for the surprice, we SCRABE off the PAINT that have been painted onto the PA hahahahah

As you see, not only UEM's are made fakes, hehe

Regards
