Hello Everyone I got an iphone 11 which came with no bluetooth and wifi. So I have reballed the layers the bluetooth and wifi was back but lost the imei so reballed the baseband ic. But it was still same so reballed bbpmu too. But now when I try to restore it, it gives me an error -1 on 95% of restore. Same on 3utools and itunes. But on 3 utools I got an error message as: Error code: -1 Code explanation: AMRestorePerformRestoreModeRestoreWithError failed with error: -1 Anyone any idea? Reball the layers again or do I need to check something else? UPDATE: Tried to restore it with only top board and had same result.
hello there, It looks like you’re having trouble registering your “Secure Enclave” in the system registry. A lot of variables are responsible for this, but 95% of system loading is telling. Desolder the sandwich again and check the values of the stockholm sub-system. I’m guessing a problem in the continuity of the interposer - it happens all the time, but really the reason can be anything - even a capacitor that has lost its resurs. regards and fingers crossing.
I have sorted that but having a similiar problem and getting “Error code: 9 Code explanation: AMRestorePerformRestoreModeRestoreWithError failed with error: 9 " on 3utools itunes flash mode around 60% or 70% . And also trying to restore on board tester. Haven’t soldered the layers yet. Do you think that it is a sandwich layers connection problem again? Or might it be really a usb problem as it is written on 3utools because I got this error on itunes logs too: “[05:40:54.0826] <Restore Device 000002AC59355BF0>: operation 55 progress 0 [05:40:55.0895] Looking up device with muxID:7 [05:40:55.0895] Muxed device disconnected with ECID: 0x36D3402E [05:40:55.0895] RestoreOS mode device disconnected [05:40:55.0895] RestoreOS device removed before restored completed [05:40:55.0905] recv(5936, 4) failed: connection closed [05:40:55.0905] unable to read message size: -1 [05:40:55.0905] Failed to receive message from device, might be connection problem with USB host.

Change the nfc_s chip? or something else?
