So I burnt an SD card with the latest Debian system and ran all updates, including the instructions from Important note about the new MNT Pocket Reform kernel and firmware updates 20260808 (updated) - #22 by myrovh .
It looks like all Firmware has been upgraded: 20260808 for both SC and HID.
The SD card os boots, and I tried running both reform-flash-uboot emc ( this has been renamed, I don’t recall what the next attempt was) and also reform-setup-encrypted-disk
Unfortunately, now neither my EMC nor my SD drive (WD_Black SN750 SE drive 500gb) are being recognized. The SD Card is in the Disks, but neither additional drives are visible.
