Database [Q] Debugging missing NAND Block device

Hello,

I have a SM-P600 (32G) with failed factory reset that left the device soft-bricked so that booting to Download and recovery works, but OS-booting leaves the device freezed after boot animations (With stock-ROM). Flashing new recovery programs work and below results are from ABD Shell with CWM recovery flashed to the device.

Below are results from /proc/mounts, /partitions and /devices. It seems that NAND block device or its partitions are not listed in results.
I was wondering what can be the reasons for this behavior, and what can be done in order to get the NAND device back online?

Is there a way to manually re-initialize the device? Or some debugging tips to narrow down the problem?

Your help will be much appreciated if I manage to get this brick back alive without buying a new system board for it.
