I had an HTC One S device which suddenly turned off and refused to start. On giving to the service centre, it turns out the device needs replacement of an item 'PCBA-MAIN BOARD WITH SKU ID MS' which alone is costing me Rs 10000. I chose not to repair it with them. So i plan to visit a local phone repair shop and give it to them to repair it.
My query is, that the phone had some important private stuff (phone was locked though) before it went kaput. Now this local repair shop, can it in any way access this data while/after repairing the phone in anyway? HTC service centre would not do that because they are bound by legal terms. Please advise.
