one of my Cisco 7970 phones went off in "bricked like" state (performing reset sequence over and over). I've serached forums and got to HARD reset solution. But upgrading stops with "Write error" at a longer file apps70.1-1-2-26.sbn.
I've found a hint of using some of older versions of Firmware first (versions 6.xx or 7.xx) and then upgrade to current version. But I only have current one (I think it is v 8.xx SCCP FW) and would kindly ask if anyone has one of previous versions to try it...
Thanks in advance,
