    Hacking Hardware Picofly - a HWFLY switch modchip

    MOSFET shorts power rail of boot processor to cause a glitch. In pulse it handles 20-40A, so you need to use short and thick wires. 0.2 mm wire is good for this job.

    Put your mosfet closer to capacitor and use thicker wires for source and drain

    what about this?: did you moved this ic's also from an orange board? Also you could try to install picofly, if hekate will load its UI, then all you PMIC's and DDR is not dead.

    hi, is your original MAX77812 had any defects visible under the microscope? Also make sure your new IC has no defects and sit on the board properly. Is any voltages present on its phases when you see the blue screen? This IC is vital for SDRAM I/O, so its should be enabled on early stages when...

    secondary PMIC MAX77812 was a culprit in my case, did you checked it already? https://gbatemp.net/threads/picofly-a-hwfly-switch-modchip.622701/post-10346964

    I bought a faulty Switch Lite with the same problem as you described. Guy tried to install hwfly RP2040(look at photo) and end up with broken console. He broke CMD line and SP2 capacitor. With broken CMD line and without chip console looks totally dead just a black screen when you try to turn...

    Hi, can you share a link to this particular datasheet? Hey guys, does anybody has desoldered EMMC BGA153 and crappy OLED DAT0 cable? Can we just flip over this EMMC chip and put this cable above to see if DAT0 on cable shorts neighbour DAT1? Is that make sense?

    Hacking Hardware Picofly - a HWFLY switch modchip

    should we use a pull-down resistor on the G when installing MOSFET directly to the APU? As described by @SQc04: "The pull-down resistor keeps the gate of the FET low in the default state, and if there is no resistance, the default state of the gate of the FET is high-impedance, which may...
