Soft-brick? How to fix "An Error Occurred While Updating The Device Software" Galaxy Tab A SM-T510

[micheldupont]

Hi,

When trying to flash TWRP, the cable disconnected and the device (Galaxy Tab A SM-T510) shows this error : "An Error Occurred While Updating The Device Software"
Samsung SmartSwitch doesn't seem to work on PC and Mac OS.
FRP Hijacker doesn't show the SM-T510 device in the list.

What can I do to undo the soft brick ?

Thanks.
