Hey everyone,

I'm running into an issue trying to update my device that uses the YiHi SX550J chipset (I believe the latest version was V8101 or similar).

The official YiHi/SXmini download center seems to be currently inaccessible or is giving connection errors, and I can't find a working mirror or a direct download link anywhere else.

Does anyone happen to have the official firmware file for the SX550J chip saved that they could share or link to?

I'm primarily looking for the .bin or .rar file needed to update the chip using the SXi-Q software. Any help would be greatly appreciated!

Thanks in advance.
 
This is what I see in the download center. Until two months ago, there was a lot more firmware available. It is probably under construction again.

When I needed information about the SXmini SL Class V2 chipset, I filled out the contact form and received an email from jenny@yihisxmini.com
Try to contact her directly if you have problems accessing the contact form on the website.
