there is a file called feature_lcd.lcdm in prodnv and feature partitions, maybe is a calibration file?

what's the phone model? and did you take note of the build number of the phone before flashing it?
have you used this stock rom to successfully flash this device in the past?

i tried to download many times and everytime flashes ok, i tried other .pac files from other carriers too, all .pacs flash ok and boots, i compare image file sizes when spd flash tool extracts in download carpet, all .pac files are the same and the file sizes match

but wait, when i mount prodnv image from a twrp backup, these got more files named connectivity configure and other things, i got a backup for wfixnv1 partition in emmc.win format and cant flash it, it looks like my twrp backup have more files in prodnv, wfixnv1 and feature partitions than the stock .pac file, but, my problem is not sim or connectivity, just LCD works weird, i use disk internals for mount the .img files and compare with the stock ones, the main problem is twrp recovery, easily i can restore my backups but, there is no lcd touch working
