Help! Jumper T8SG V2.0 plus was created by K2-tokyo
I bought one from Banggood one week ago. First of all, I changed the mode 2 to mode 3. Then, for 2~3 days I was learning and gave settings for a XK K110 helicopter. It was very strange that the transmitter bound the K110 receiver, but the throttle channel did not work, and that the swash servos moved but no gyro behavior. (This receiver is normal for a Futaba transmitter). After then, (one or 2 hours after) the transmitter did not start, only shows a wire icon. I have never given any physical nor electrical damages.
What should I do? Return back to Banggood for a new replacement?

Most likely transmitter filesystem is damaged. Try to format transmitter USB drive and copy filesystem from t8sg_v2_plus firmware archive. You can also update firmware.

If you have any questions about USB mode and firmware update, read DEVO 7E/10/12E manual:

To activate t8sg_v2_plus firmware update mode, press EXT button and SHORT press Power On.

Will be better to use Windows 7, you can install Walkera DfuSe Upgrade Tool v2.31 to update firmware and format USB drive. Connect Mini-USB cable to transmitter (on the top of transmitter) and to PC, you will see new removable drive, select Format... and format it with default options.

Thank you for advices. The method by Windows 7 did not work. Devention Dfuse USB Upgrade Tool did not recognize the transmitter. Only Java's DeviationUpload-0.9.0 in MacOS X recognized the transmitter and completed the firmware update, and after that completed the files. But nothing changed.

Do you try format transmitter USB drive?

With Windows 7 and Devention Dfuse USB Upgrade Tool you need manually install USB driver from program folder.

Solved! Thank you very much.
Drivers were installed correctly. But Devention Dfuse USB Upgrade Tool did not recognize the transmitter.
Once, I formatted the USB disk quickly, and copied the files by the mouse. Then nothing changed. Now I formatted it not quickly and copied the files by the mouse. Then the transmitter revived!
Though, the throttle channel for a S-FHSS receiver does not work.

Just for sure you can try different build based on stable v5.0.0 release with updated protocols, you will need full install since filesystem is different.

Concerning the throttle and the gyro channels, my stick calibrations were not correct! Now the two channels work. Thank you very much!
