Hurricane Epic ROM Request

This is my grandfathers phone that he bought but he has some kind of virus on it. Factory resetting it didn’t help. He has already bought a new phone.
I have searched the internet but I can’t find a ROM for the phone.

I have just searched but I can’t find ‘Epic’ phone.
What are the specs of the device ? Was it delivered with Android 8.1 or above ?
If yes, you could try a eOS pie GSI [HOWTO] install eOS GSI on a Treble device - new GSI added June 14th

Seems the internet doesn’t have much on it anymore, might have been available in very few markets apart from South Africa?
Perhaps you could contact the company about getting the last firmware file they had for it?

Here are still some basic specs:

'Hurricane Epic 5.5"

SIM: 5.5 inch - HD Screen
Size: Dual Sim

Primary: 5 MP with flash
Secondary: 2 MP

Card Slot: microSD with up to 32 GB - dedicated slot
Internal Storage and RAM: 8 GB with 1 GB RAM

OS: Android 7.0 Nougat

Chipset: SPREADTRUM 7731C

Type: High capacity 2400mAh battery

Other features
FM Radio
Protective Cover and Screen Protector inclusive" ’

I have contacted Hurricane about the issue and asked they just told me to tale it to a service center or something. I then asked for the firmware files and instructions but that didn’t reply to that.
I also can’t find a custom ROM for the device.

It was shipped with android 7. So there is no real chance for running a GSI on it

And it would be difficult to get the needed sources for building eOS rom.

Is there another option?
