Hey @mattytrog, I've been having a similar issue with my switch too... The data lines wont accept the payload data. I took the trinket mod wires completely off the board and i still cant even use dongle payload injector either. Switch charges and also sends over HDMI when in dock... but cant trigger bootloader in RCM mode. Does go into RCM mode though... just wont respond to any other device or show up as APX in PC devices. Any ideas?
