I was unable to replicate this with my iTouch and iOS 12.1.3
User can no longer replicate the issue and it is working for him now (based on BAO-120-59505 ).

Reopen, user supplied new information, I'll ask him for a copy of iTunesCDB prior to iTunes sync and after. |

Another user reported issue. |

I was unable to replicate this (see notes at 0015375) when testing with an iPhone X (iOS 12.1.2), MMW 4.1.23, and iTunes 12.9.2.6 (64-bit). What I did find, that may be relevant to this issue, is that whenever I ran iExplorer (the app that I was using to access iTunesCDB) with the iPhone connected, then on the next time I ran iTunes with the phone connected, a different error would result as soon as iTunes was run:
"The iPhone 'Ari's iphone X" cannot be synced. An unknown error occurred (-54).
However, initiating a sync with iTunes --> successful synchronization, and elimination of the error when iTunes was run subsequently.
Could this particular user's case be caused by an app similar to iExplorer? |

OK, I asked him. |

It seems that the issue happens with "iPhone XR" only. Not with "iPhone X".
The original user has stopped the communication, debugging further via forums with other users:

Some tech/dev notes:
I have been debugging this remotely via ticket BAO-120-59505 (as I don't have iPhone XR/XS) and found:
- the difference is in the AB hash value (diff between iTunesCDB generated by MM and generated by iTunes)
- the AB hash is calculated from iTunesCDB content + some random part + device UDID
- the UDID for iPhone XR/XS is in the new format, see: https://www.theiphonewiki.com/wiki/UDID
- I tried supplying the new UDID for the hash calculation in various forms, but the error still appears in iTunes
- I also tried to calculate the old style UDID to supply, i.e. SHA1(serial + ECID + wifiMac + bluetoothMac) -- still no luck :-/
So probably the AB hash is calculated another way for the new models.
I used workaround of writing MediaMonkeyCDB (instead of iTunesCDB) with following downsides:
- music synced by MM won't be visible in iTunes anymore, but will be still visible and playable by iPhone itself
- iTunes sync will wipe music synced by MM
This is applied only for the new models (iPhone XR/XS) with the new UDID format.
This workaround is added in 4.1.24.1883 |

This is still an issue for some iPhone XR models.
Ticket JFO-481-83317 , https://www.mediamonkey.com/forum/viewtopic.php?f=12&t=93591&e=1&view=unread#p461154
User's iPhone XR has a little bit different USB ID format ( USB\VID_05AC&PID_12A8\8&14C74800&0&4 instead of USB\VID_05AC&PID_12A8\0000802000010D4E2EE8003A ) and this is the reason why MM is not detecting it correctly and considers it as the old style iPhone/iPod (resulting in bad iTunesCDB write).

Fixed in 4.1.25.1888 and merged to 5.0.0.2195
Posted testing DLL to user for confirming the fix. |
|
|
|
Verified 1888
No regressions found on iPod Touch 4G. Done two factory resets and and 2x MM4/iTunes syncs to see if iTunes would report recovery needed. |

User from ticket JFO-481-83317 confirmed the fix, so closing for now |
