Uninstalled system applications appear after reboot on HTC Desire X I have tried a lot of things which mentioned in different forums such as:


delete using root ES File Explorer.
delete apk files from /system/app.
clear Dalvik cache after uninstall (manually removing /data/dalvik-cache and /cache/dalvik-cache and using CWM recovery.
all mentioned earlier together several times.
Even reinstall ROM wiping data/factory reset and clearing Dalvik cache using recovery.


But no result. And  I get something like this on startup if I clear Dalvik 
 cache:

So there is a location from where OS gets these apps, isn't it? How can I get rid of these redundant apps?

Update:

Here a link where I downloaded ROM: https://forum.xda-developers.com/showthread.php?t=2249760
I fixed it by enabling S-OFF on my device. Here more details https://androidforums.com/threads/uninstalled-system-applications-appear-after-reboot-on-htc-desire-x.1178166/#post-7596175
