Change the splash screen on moto e4 plus owens I was rooting my device and I screwed it up but I got twrp to runs and I installed Lineage OS. But after I restarted my device, there is a tiny n/a in the corner until the Lineage's logo appears. I searched for a while but came up dry. It's not that bad but I would like something else to be shown instead of n/a. Thanks for any help.
There are two ways of doing it, but both methods will require some files.

Method 1: fastboot


Aquire a splashscreen file in the format of '.bin'. You can either search for 
splashscreen .bin files made for your device, or find a tool that allows you to convert and image to a splashscreen .bin.
Put your phone in bootloader mode manually or with adb:


adb reboot bootloader



Flash the new logo to the device:


fastboot flash logo filename.bin


Method 2: TWRP


Install TWRP as your bootloader (in your case you already have)
Aquire a zip file specifically crafted for your device to flash a splashscreen logo*
Copy the zip to your phone via OTG or SD-card and flash it with TWRP


*Note: as far as I've seen the zip file only needs to contain three files:


META-INF/com/google/android/update-binary
META-INF/com/google/android/updater-script
logo.bin OR splash.bin OR logo.img


But they have to be specifically crafted for your device, and in order to do that you will need a tool. See this XDA thread to find a guide with tools for your device.

Edit: I checked the thread for your phones product line, it looks like the E4 Plus is unsupported, at least nobody has added support for it here. You might need to look elsewhere for a tool that can make images for your phone.
