The miui rom was download from here, the rom is based on Android 10. After generating the system.img file and mount it to the system directory, using the baksmali-2.4.0.jar to deodex an odex file get following messages:

$ file miui/umi/system.img 
miui/umi/system.img: Linux rev 1.0 ext2 filesystem data (mounted or unclean), UUID=4729639d-b5f2-5cc1-a120-9ac5f788683c (extents) (large files) (huge files)

$ sudo mount miui/umi/system.img miui/system/

$ java -jar romutils/baksmali-2.4.0.jar x miui/system/system/framework/oat/arm64/services.odex

Maybe the baksmali-2.4.0.jar does not support Android 10? Or the root cause is the ext2 file format?

Are you sure it needs to be deodexed? If the .odex file has no dex files, it's likely the original dex files are still in the .jar file.
