Is there a master RESET switch for T8SG?

I have the original JUMPER T8SG from Banggood.com with the Ver 5.x.x software.
I have programmed several models and things were working fine,
Then on one download of a model6.ini the system could not find any models greater than model5.ini
At the same time, programs that worked before now loose some of their PAGEswhen you look in MIXERS. But uploading the same model
shows that all the PAGEs are present in the .ini file. I tried downloading all the original files that I backed up when
I first got the system. Did not help. Cannot find a Defus for JUMPER T8SG and I don't think there are any
software downloads for the JUMPER T8SG (version 1)..

So I am looking to see if there is a master reset which will reboot the T8SG to is "factory" state.,
Any help would be greatly appreciated.

Builds of the most recent software are here . deviation-t8sg-v5.0.0-f6f940d is the build for version 1 t8sg.

I checked all lfiles in the 8TSG. I have no .txt files or anything else that is not the standard .ini or .zip files
There is one binary file that is large but I do not remember its extension, Something like .duf

I have a complete dump or the 8TSG when I first got it and I compared all files to that list.
All 30 of the .ini files are on the 8TSG but the "LOAD" menu only allows you to find .ini in the first 5

Later I did a "re bind" of my system and when I did that, then all 30 .ini files were available to be selected
but that was from my complete reload of all software on the 8TSG

Did not know the nightly builds ever supported the T8SG.
Do you know what DeFu linker software will allow me to downoad these nightly builds to my 8TSG.
Much thanks.

I use the 2.31 version here .

This link is from "Downloads" over in the left column.

hexfet,
I used the 2.31 version and my 8TSG is not found by that program. I have tried all the combinations of ENT and POWER ON and USB menus.
Nothing I do makes the 8TSG seen by the 2.31 program. But I clearly see all the files in my Tx on the USB channel.

Is there some "magic" to get the 8TSG to be seen by the DeFu linker program? Much thanks.

Here's a recent thread on this subject. It's usually a driver issue.

Thanks for sharing mate
