I ported a Custom ROM to my phone and I try to flash it via TWRP 3.2.1.0 but it ends with error
"Custom theme Version does not match TWRP Version
Patching system image unconditionally
E1001:Failed to update system image
Updater Process ends with Error:7"
N.B**I replaced the mount point of my phone on the updater script.
**I deleted the assert line on the updter script.
**I don't apply wipe of system,catch and data of my stock ROM.
**The port ROM system format is system.new.dat but I changed it default system folder which means the zip contains only META-INF,System Folder and boot.img
