Oh dear, seems too much guinness removes the requirement to back up before making changes Seems I have screwed my market up. Flashed the blacked out market, which didn't work but now I have the following problem. In Settings Applications I can see the following Market 1.25MB Market Feedback Agent 117KB Market Updater 4.00KB Opening the market from here all the usual options (clear data, clear cache, uninstall updates etc are greyed out) Opening the market from the icon in the app draw results in the following message The Application Market (process com.android.vending) has stopped unexpectedly. Please try again. There seems to be no way to update, uninstall or apply a simple fix. Anyone got any ideas?
