Accidentally Erased internal SD memory

[Bandschaaf]

Dear Pine64 Community,

Unfortunately, I made a mistake while trying to install a new operating system on my PineTab and accidentally erased the BIOS (UEFI). Here are the details of what happened:

What Happened:

• I was in the process of installing a new operating system on my PineTab and inadvertently followed the wrong steps, resulting in the internal drive, including the BIOS, being completely wiped.
  
• The device now fails to boot, and I have no access to the BIOS to attempt to troubleshoot the issue.
  

What I've Tried:

• I attempted to boot the device from a bootable SD card, but without success.
  
• I also tried starting into MASKROM mode, to no avail. (the adapter shows lights, so it is active)
  

Any suggestions, tips, or guidance would be greatly appreciated. Thank you in advance for your assistance!
