How are you all doing? Sorry If this is another stupid question. But I am trying to install the new cyanogenmod 22.214.171.124 through ROM Manager. I select the option to Backup current ROM and wipe cache and data. The backup works correctly but as it's getting ready to install the new ROM I get the message can't format SDEXT. What does this mean and how can I fix this. Thanks in advance to those who respond.
