iPhone 6s Not Turning On And Damaged NAND – Repair Case. 

Fixed an iPhone 6s of one of our fans. He claimed that the phone stuck on the Apple logo at first, but after being repaired by another company, the faulty degenerated to not turning on. Then he delivered the phone to CINO for a better solution. After inspection, we found out that the phone had been disassembled and repaired. For instance, the NAND chip had been damaged and the black adhesive had been removed, and so on.
