white text: with beginners were unskilled and cut over seal, unintentional made a break at this semi eeprom and made error 14 when restored ->replace another one is OK, 5s can be use.
NOTE: Ipad air 1 3G edition downgrade to wifi very easy. You just need to take off all resistances in frames so that they turn to 0000 -> become wifi edition. In VietNam, the majority way is removing resistor R1506. Sometime, devices have R1505 -> remove it, if not, itunes will recognize to iphone. After remove resistor, device stuck with DFU -> need to restore to become Wifi edition.
