S21 FE from Metro PCS. An Error has occurred while updating the device software!

[uws101]

Situation:
Had Google logged in
Device had PIN protection.
SM-G990U2

Errors while using ODIN patched (Odin3 v3.14.1_3B_PatcheD)::
An Error has occurred while updating the device software!
Image Extraction Failed

How I got here:
Metro PCS S21 FE (SM-G990U2) was flashed in 2023 with SM-G990U3/XAA
All was well.
Subsequent Android updates went fine until the recent one - it said invalid sim pointing to SIM 2 which does not exist.
But I am also unable to turn off SIM 2 - both SIMs are always on.

So I wanted to revert back to TMK, SM-G990U2/TMK
I went for HOME_CSC hoping I will have all the settings remain. So it had device pin on and Google a/c logged in.

While doing it, it was unsuccessful - got the error of "An Error has occurred while updating the device software"
Later tried with CSC instead of HOME_CSC, no luck.

Also tried Smart Switch which detected G990U2 - it tried Emergency recovery and did not finish.

Tried FRU to remove google a/c but FRU software did not have my model.

How can I fix this - I am not an expert. Pls help. Spent several days on it.

I fixed it. FRU to remove the error. Then ODIN to clean install FW
