I have accidentally wiped phone system OS using TWRP; is this fixable?

[lethaljoe]

As title says, by mistake I have wiped everything: Dalvik Cache, System, Data, Internal Storage, Cache, Micro SD. Everything.

How did this happen? Well, yesterday I ran into some problems after first rooting my 7PRO on Friday night. I couldn't get past the unlocked bootloader message. So eventfully I just decided to boot into TWRP and wipe the device. Not understanding what I was doing I chose wipe and ticked all the above listed items. I should have just done a factory reset I'm aware now.

I can't get past the fastboot screen. I select recovery mode and it just sends be straight back to fastboot. I figured I would just sideload a custom rom through TWRP, but I cant get back to it again. I cant install TWRP because my phone isn't detected on my computer now.

I'm hoping this is fixable. Because I'm fairly certain I cant get back from this. Maybe someone has some fixes. Cheers

Is the phone detected in fastboot mode?

Install the system wide adb-fastboot drivers.

If you can get the phone to be detected in fastboot mode you could send some commands to reboot into recovery mode or try flashing twrp again
