bricked it?

[bcnaz]

two days in and it's already bricked! D:

after flashing a custom-built manjaro image to emmc, the pbp won't boot any more. not from emmc, but also not from sdcards (tried multiple) or usb sticks (tried multiple), neither with the default debian image nor with a stock manjaro image, regardless of whether emmc is enabled or disabled via the hardware switch (or even present). power led stays off, whether a uart cable is connected or not (or the uart is even enabled via switch).

looking at uart logs it seems that the chip doesn't even reach uboot. when booting with emmc disabled it comes out of DDR init just fine, but the boot stage isn't happy:

is this recoverable?

   Yes,   There are several Threads/Posts  that can help you recover.

Though if this a brand new PBP, ? You may also want to check some of the other items :

If the eMMC is seated all the way, is the ribbon cable to the sd card slot secure.....

I opened my PBP before turning it on the first time, I found the eMMC was not all the way pushed into the socket.
