OEM Android OS is the version of Android installed on a handset that’s fresh out of the box. In most cases, it’s the stock (original) version of Android with skin and additional features baked in. Unfortunately, some OEMs pack these versions of Android with bloatware, a series of applications that you’ll probably never need and are difficult to remove.

Now it’s time to copy over your custom Android ROM and Gapps. Find the ‘Mount’ section of TWRP and select ‘Enable MTP option’. Then, connect your handset to your PC or Mac via a USB data cable and transfer both files.

Go back to the main menu of TWRP and select ‘Install’. Which will prompt you to locate the files you’ve just copied over. Select the ROM first then swipe to install, then repeat the same process for Gapps. Finally, select ‘Reboot to System’.

If your handset doesn’t boot correctly, try installing the ROM, reboot back into recovery, then install Gapps. For some reason, a reboot is needed with some handset make and models in-between installations.
