When I try to update my Cisco SPA525G2 (currently on 7.5.5) to 7.5.6 I get the following error:
IMAGE CRC Error
I also tried upgrading by using the following url:
where the firmware file originally was named:
Another issue that is ocurring somtimes is after populating the attendant console, the phone performs a factory reset.
We are using the SPA525G2 as a stand-alone SIP phone, I tried to manage it using CCA, but I am unable to authenticate for whatever reason (cisco cisco, admin admin and other variations did not work)
How can I force an firmware upgrade, or is there something else wrong?
