What changes
Dataset 720C: slot zh_HK → ru_RU, CRC32 recalculated.
Details
The MMI menu and the cluster switch from Cantonese to Russian. The first Dashboard screen (Chinese), the main menu (English), voice control and SMS stay as they are — the Asian firmware has no Russian resources for them. The MMI restarts after writing; archived faults may appear in units 17 and 75. Length and all other bytes are preserved, so rollback is a normal write of the original from the backup.
