One customer reported that his Xhorse VVDI Key Tool Plus appeared two errors during update: COE1-FC32 (synchronization failed) and error 20_58 (firmware update failed). It failed to download update, the CE firmware was empty, and the server connection also failed.
Xhorsetool.com engineer replied:
You’d better send your key tool plus back for a factory repair.
