My Mix2S got UFS slow down after WOA

Hi guys~

I got a problem with Mix2S.
I successfully installed WOA with keep Android OS.
Both are worked well over somedays.
But now I faced with very slow speed of UFS(storage)
When I check the storage speed on both Windows11 and Android.
It shows just Write 40~50MB/s and Read 12~15MMB/s.
I don’t know why happened this situation.
Booting time also very slow(4~5 times longer than normal).
Also applications are running very slow in first time execution.
Anyone have this kind of problem with Renegade? and Is there a way to fix this?

Probably your UFS is worn out
