Qflipper fails to repair, bricked device

Troubleshooting
#1

upon receiving my flipper I was unable to get it to update through mobile or pc even though I factory reset and tried several different SD cards (all of which I know are legit). Today I was able to place the flipper into recovery mode and qflipper recognized it, after clicking repair it failed and closed the program as well as bricked the flipper itself. Ive tried pressing the keys for 30sec and reconnecting, qflipper reads it but fails and closes everytime I click REPAIR. This is the log, any Ideas?

Tried different usb cables and a different usb port? Another recent user complained the cable was faulty , or it might be the usb3 port that is being annoying? Since the lib usb fail to find the device it might be a physical issue in the connection ? DFU mode seems to work so it should be fixable.

Both the cable and the port work fine, I charged up my old windows laptop after I made this post and qflipper worked just fine on that. So the flipper works fine I just cant figure out what was wrong with running it on linux since I double checked both the port and cable and they both work fine.

If you try to get it in DFU, and after try to connect it to USB, then do a lsusb , does it change device ID/work somewhat ? Or even better, first DFU, connect , then poweron machine, maybe there is something in load at startup that conflicts/locks drivers or something related to libusb? do you also play with RTL sdr usb or something like that?
