Lattapanda V1 4/64 Stuck at Boot Screen

Hi, 
I have a Lattepanda V1 (S70CR200-CC55E). I went into the BIOs and Restored Optimal Defaults.
After doing that, I am unable to get into the BIOs screen again even after repeatedly pressing ESC and DEL on the Keyboard.
The Screen just shows the default lattepanda logo on a black background. 

Things I have tried to troubleshoot
1. Tried flashing the BIOs via a USB flashdrive 
> https://github.com/LattePandaTeam/Latte ... 350%20only
2. Re-install Windows 10 Home
> https://docs.lattepanda.com/content/1st_edition/os/

Both options still left me at the same screen, essentially leaving me with a brick. I can no longer boot into Windows 10. 

In terms of PSU, I am using the default RPi power supply (5V/ 2.5A)

Any help would be greatly appreciated. 
Thank You and Have a Nice Day.
