Bootloader locks the nand, so there is no way to make it writable without reflash.

In openmode aegis uses different encryption key than in open mode, thats the reason why things start to fail if you first have configured account details first in secure-mode. If you go directly to openmode after full reflash without booting to secure mode at all, then all your aegis secure stores are created with open mode key, but if you have booted to secure mode before going to open, then there will be encryption key conflicts, ie you need to delete securemode stores and create them again (so it will use openmode keys).
