Post Hardware issues with NAND?

I got a utilte pro since last year and since the kernel 3.10 was released I can finally use it as AP without crooked USB-wifi dongles (2 network cards make an exceptionable router, but a router without WiFi AP is useless with the amount of mobile devices we have).
Now since I tried again with the kernel and changed the uboot flash to boot from the old kernels as my modified kernel (additionally removed drivers) failed to boot and such I came across an issue that I cannot write to the NAND anymore. Neither from within the OS via fw_setenv now via saveenv in u-boot.
fw_setenv doesn't return anything, fw_printenv returns the old value.
# setenv kernel
does the job, saveenv also reports doing its job as it is writing the flash, printenv shows the new value then (as per setenv). After a reset the old value is back (uImage for example, whereas I expected

Fixed it.
I did a uboot update: ... oot_Update
From the ubuntu based image I couldn't update at first so I went with the method of booting uboot from the SD-card into my normal system (Gentoo). From there I changed, finally successful, the kernel parameter again. This time it was obviously saved.
Then the updatescript from the utilite ubuntu installation then worked.
Actually it updated the uboot from a 2009-version to a 2014.

Actually this helped another issue. I replaced the SSD with another 256GB SSD. Sicne that time the utilite didn't boot without help as it would not recognize the SSD on the SATA port after a cold boot. It would need a "reset" on the serial console to actually boot up. Now i don't need that anymore :)
