Partitioning RB4011iGS+

This device breaks when it is partioned. I tried it with factory firmware/routerOS and with 6.46.4:

Netinstall does not help while partitioned - it only boot up, when I revert to one partition in boot menu (console). On reverting no netinstall is needed. Yust toggling partion count result in good/bad condition.

Do I have a chance to get working partions?
