Btw I have already sent an email to Chuwi customer service ([service@chuwi.com](mailto:service@chuwi.com)), but I am awaiting their response due to the weekend.

I am requesting the raw `.bin` BIOS dump file specifically for the **CWI519** model (S/N: **ZMiniBMM2H230400660** , J4125, 12GB RAM) because my BIOS chip is corrupted and needs to be reflashed using an EEPROM programmer.

If any admin or member has the working BIOS `.bin` file for this specific S/N batch, please kindly share the download link here.

Thank you!
