Hi, I started this business in the Apple world, repairing damaged screens, buttons and connectors.
But since that market is crowded here in the Netherlands, I started looking towards repairing Samsung mobiles.
Hardware-repairs are almost every time related to broken screens.
But software can be a problem too; it seems that the S3-mobiles "loose their IMEI reguarly".
As this seems to be an interesting market to help people restore their original IMEI, I started with websites that claim to change IMEI, but noticed that in most cases, it wouldn't work.
Then I bought a Z3X-box.
And I must say: that box hasn't let me down!
I repaired two Samsungs S3's already and passed them to friends/family and I reserved one for myself.
Also repaired a I9000 that didn't show much live anymore.
I think the Z3X-box is really "value for money".
