Flashing MK2 firmware (+ custom palette) bricked my MK2?

[pnxl]

self explanatory, my mk2 won't turn on and holding the four buttons at the top won't go into bootloader

simply does nothing upon receiving power not even the fireworks/water droplet animation

[pnxl]

you could say the mk2 has a faulty ass port (and i won't blame you for thinking that) but it was working right before i flashed the firmware w custom palette

uhh i don't write directly to any memory regions here, i just sysex send the update to the mk2 and the bootloader does all the writing and checksums

if something failed so badly it would have failed no matter what flashing/updating utility you used

are you 100% certain bootloader is impossible to enter?

if it is a real brick you can fix using an st-link and full flash (bootloader+firmware) dump of MK2 (i can provide over discord)

(the images are dead because of discord cdn changes but they wouldn't help much anyway as they are for pro)

yeah windows doesn't even acknowledge that there's a device plugged in, and there's no sign of power coming into the mk2 either

tried good known cable, nothing, tried another cable, nothing

all the cables were tested being plugged into a usb hub, directly into the computer, and even directly to a power source (a charger)

they're all tested with being plugged in halfway too (you know how trashy mk2 usb ports are)

[pnxl]

i took apart the MK2 to have a look at the USB connection, does this look alright to you? could it be a bad solder point instead?

weird, dunno
