T8SG USB problem

T8SG USB problem was created by Goochman
I just purchased a used T8SG and am having a problem connecting it to my PC.
I am new to all of this so hopefully I am just confused.
It’s one of the older models so I took the unit apart connected the USB cable to my PC and to the transmitter.
I turn the transmitter on while holding the enter button and the USB symbol stays on the screen and doesn’t go away and my computer is not recognizing the transmitter.
I bought a brand new micro USB cable.
Is it possible there’s different types of micro USB cables?
Any help is appreciated.

Hello,
It's not a question of usb cables, that's for sure.

Are you trying to upgrade the firmware (bootloader mode?) or add .ini files?

Oh - and you have a battery in the TX right?

You may also need to check for an updated driver. You did download and install DFuse, right?

I use Zadig for drivers. I'll try my jumper when i get home tonight. I know sometimes I have to try different USB ports on occasion.

I’m trying to upgrade the firmware and install software for different drones but I can’t even get my PC to recognize the jumper

If you press ENT + Power On, you will get USB mode to access USB filesystem. For firmware upgrade you need press EXT + Power On, then DfuSe can detect transmitter.

Thank you guys for your help. I was finally able to get my t8sg to connect to my PC. However I am having an issue installing this--deviation-t8sg-v5.0.0-7867ad5.
I used the DFUSE upgrade tool to install the file in DFU mode with no problem.

I have been watching as many videos as I can and my problem comes when I enter usb mode after installing the firmware in DFU mode.
When I go to the drive for the TX I am not able to delete the existing files. My PC will not delete them.
iIs there another video that explains any of this in more detail?
I totally screwed up what the factory software was on the TX. I just want to be able to wipe it clean and add the new file so I can actually use this controller with the Bugs 3 drone. That is the main reason I bought this controller and I have not been able to use it.
Is there a T8sg instructionally video for dummies?
Any help appreciated.
Thanks

On my device manager that shows all the USB drives it should be under USB controllers. Also, I had to go to view, and hidden objects, and there it was! You can find the videoon Youtube if you search T8SG failure. There is also a link to the video on the Jumper website, jumperxyz.com, under the manuals and links section. I also posted my fix on my other string "T8SG Plus " Do not download STMicroelectronics" . Lengthy post, step by step, and using the manual as well. And make absolutely certain you are downloading the latest, correct, firmware.
