Try flash next build with bulk flash memory erase, then return to normal nightly build. With this build you can try format transmitter USB drive and copy filesystem from firmware archive. But don't use it permanently.

Don't forget flash normal nightly build. Do not use attached firmware for everyday use.

Thank you so much for your reply and the attachment vlad_vy.

The bulk flash memory erase appears in the DFuse tool, or when i flash the firmware, it will do the bulk erase? Will try it later when I am home and report back here.

You need flash firmware and boot once with it. You can try format USB drive and write filesystem with it, if you like.

Hi vlad_vy,

thank you so much for your relentless help, but I am still unable to get rid of the usb logo on my tx. I installed the x86 dfuse driver 1.1 x86 as well with walkera for dfuse
1) Upgrade firmware was successful in dfu mode.
2) After I exit dfu mode and remove device, I boot....usb logo still there.
3) Press ent and power, usb logo still there.
4) windows sees my drive but when format, the error persists.
5) Safely remove device, and power on, usb logo still there.

My windows is vista, have also tried on Windows 10 but the error still remains, Windows still unable to complete format. The filesystem on the 2MB storage is indicated as RAW. See pictures attached. I am totally lost. Any other suggestions?

Hello ,
From the images I see that you did not load the right file for a T8SG plus radio.
Once the file is loaded you must turn off the radio then press power and return at the same time at that time it goes to usb and you must put all the files. Then turn off the radio by pressing briefly.

Hi jp,
Thanks for the reply. I was loading the bulk erase firmware. Prior to this, i loaded the latest nightly build but was still unable to format. I just tried again and still not successful.

I loaded the firmware in dfu mode. Dfuse usb recognised my stm dfu. After successful upgrade, i off the tx and press return and power. Usb logo appeared but windows saw my drive. But when i formatted, the error resurfaced. I hope I didn’t miss any step. Its return and then power for usb mode and ext and power for dfu mode right?

Get a Live_Linux and check with GParted whether this space is marked as raw or if it has already a DOS label
The latter will is points you to a driver isssue on your PC. But if it is marked as raw, only a special tool will help to get around this.
In my case with my 7e I used fdisk from the linux tool box.
Good luck.

Thanks aMax.
I have a Mac, anything that I can use? The disk utility saw the drive as RAW as well.
