Product Name: Electronics shops Lot
Basically none of them work. Ive had this for a few days so i don't have any background information about these broken devices. the previous owner held all of the important information regarding the history of each device unfortunately. For the shops most part it seemed to have been a repairman as some have notes. The Samsung Galaxy says "bad board" while one of the htc phones has "password locked" written down. The rest don't have notes but are near to being toast or are toast. A couple phones go to the BIOS only while a couple show a charge indicator and don't boot. The rest don't boot. IPhones untested. Laptops don't turn on but i don't have the charger to confirm. Toshiba Samsung apple htc.
