Member: 1003091 Status: Offline Thanks Meter: 0 | iPad Pro 12.9 broken WiFi chip question. I have an iPad Pro 12.9 4G (A1652) with broken WiFi (coded as 339S00044). I've unlocked tha NAND and mounted a new chip, but coded as 339S00047 used in iPad Pro 12.9 WIFI since it's the same mainbord with the difference of without the 4G stuff and because 339S00044 was hard to find around. Bluetooth is recognized and works, WiFi not (no MAC address, no toggle switch is working). Some shops sells both the 44 and 47 version (by saying for 4G and for WIFI rispectively), someother also the 45 and I don't understand which are the differences. Is possible that the WiFi doesn't work because this? If yes, why? If not could someone have some suggestions or a schematic to try fix this problem. Thank you all. |

You know, use of different combo BT+WiFi modules for models with SIM and models with WiFi only exist from iPad Air 2 still and continue - so you need to get exactly same combo module as original one. |
