**Feature Request: Solution video to unbrick the Portenta Orange LED of Hell** … It seems that there is a high rate of "bricking" for the Arduino PortentaH7 boards being used in a robotics class, with an average of ~14% or (1 in 7 ) of boards becoming permanently stuck in an "Orange LED" state. The request is for a simplified method or video that can help users unbrick their devices, especially for those who may not have access to all the necessary debugging equipment or software. Additionally, it would be helpful to understand the root cause of the issue and why the PMIC controller is losing the ability to control the 3.3V voltage. The requestor is willing to make a video and provide software if a simplified method can be found. Below are links to forum discussions about the issue. _Issue background:_ For my Robotics class I have 21 PortentaH7 and over 2 years 3 are now permanently showing the onboard Orange LED (of Hell). One of my after school students has now got his PortentaH7 with the Orange LED. Some issues seem to be solved by just connecting another 3V3 from another board to the portenta 3V3 (and GND) then burning the Portenta bootloader. (I wish that worked but doesn't seem to for me) Other solutions seem to be using 2 Portenta with breakout boards and manually loading the PMIC code, then flashing the firmware.
