PBP won’t boot from eMMC after Debian update / Tow-Boot installer won’t boot from SD

Since in OP you said there was a green led (I assume no SD inserted) there must be something on emmc
When no uboot (really idbloader) can be found, there are no leds, you think it is dead
So, you must have done something wrong
Point ghex at /dev/emmc (mmcblk....) and go sector 64
idbloader ALWAYS (all versions) has file signature 3b 8c dc fc
This is how the boot rom 'knows' that is 'right' code (and to stop looking)
or dd if=/dev/emmc of=idb.test bs=512 skip=64 count=512 (idbloader varies,, 160K-210K)
