Testimonial: "although this was very helpful i decided to take it to a shop and let them sort it out thanks for the help"
well, from what is indicated in the USB manual for your Brother, check that none of the below issues is causing this.
- Ensure that USB media contains data for no more than 200 embroidery patterns since Embroidery patterns cannot be transferred to the machine if the USB media contains data for more than 200 embroidery patterns. If this is the case, reduce the number of designs saved on the USB media.
- if the embroidery designs contain too many colors (this number may vary within the designs themselves), it may not be possible to transfer an embroidery pattern to the machine, even if there are less than 200 embroidery patterns that have been saved on the USB media. In this case also, reduce the number of designs saved on the USB media.
- Save the patterns in the root directory of the USB media. If embroidery data is saved in a folder on USB media, that embroidery data cannot be retrieved by the machine.

This happened to me and I eventually realized that there is a small door flap at the top near the "4" in the threading series that can get stuck open. Normally this flap goes up and down with the presser foot, but if it gets stuck open even when the presser foot is down, tapping it or closing it manually will make the error go away.

F05 error, speed sensor. I fixed successfully 2 of those. Speed sensor is located on a small board, under a protective plastic, located over the main front board. Remove front panel and bobin winder assembly. Remove the 2 screws of the small board. Remve CAREFULLY the small bord. Under, on the main shaft, are located the needle positionning sensors and the wheel of the speed sensor (left wheel on the shaft). The speed sensor is located on the board itself, it's very small. Clean carefully both the wheel and the sensor with Q-Tips and alchool, reassemble the whole thing and it should restart.
While U are there, take a thin nozzle oiler and lubrificate all the suppots of upper and lower shaft, all the needle bar mechanism and rotary hook central shaft and gears WITH VERY THICK oil. Needle bas assembly is the most critical point. I have 14 of those machines, almost all of those seized there before I learn how to lubrificate it. Also seized on the bottom shaft and on rotary hook pin

SOURCE: How to oil brother PE 770
Brother says it should not be oiled but having 14 of those, I know that it has to be done but a Brother technician will not do that. OILING the machine may cause F05 speed sensor error. See how to solve it under this label.
U need to remove the complete front plastic panel. 3 screws on the top (2 lower the handles, 1 at upper right. Remove 1 screw at the center bottom of the rear panel. Remove both left top/ bottom panels (1 screw each) then the horizontal bottom left panle (2 screws). All the balance is fixed with clips.
First undo the 2 clips under the machine than carefully unclip everywhere. Front panel have 2 wire assembly attached to main board. Regular one is easy to remove. To remove the flat one, send down the upper part of the attchment on the main board.
Don't use reg. thin white sewing machine oil, it evaporate. Use SAE 80 (differentail type) oil or something like taht. Lubrificate all 4 lower shaft supports, rotary hook gears and central pin (from the top, under the bobbin case). Then lubrificate all the upper shaf support and especially all the needle bar mechanism. U need a good light to see upper needle bar support. Lower needle bar support support is the most critical point.
