I pulled my N950 out of the drawer it's been sitting in for the past 6 or so years, in order to see if it can be made to work once again.

Tried to reflash it, but the flasher fails on both rootfs and emmc:

Code:
[Timur@timur-zen N950]$ sudo ./flasher -f -F DFL61_HARMATTAN_40.2012.21-3_PR_LEGACY_RM680-OEM1-916_ARM.bin -F DFL61_HARMATTAN_40.2012.13-7.RM680_EMMC_RM680.bin

ERROR: Failed to flash images
After trying some suggestions, I ended up flashing an old "rescue image" which lets me telnet into the device. Sadly, it looks like the eMMC and/or the NAND are dead. I'm getting a lot of ECC errors from the NAND, and a lot of I/O errors from the eMMC.

Here is the full dmesg log: https://pastebin.com/65eu3wqr
