If you have previously “modded” WidgetLocker (As described on XDA), then before updating to the latest Market version you should uninstall your modded version. Depending on how you did this you may have to do a few things.
- Uninstall WidgetLocker from System Settings > Applications > WidgetLocker > Uninstall
- If exists, remove /data/app/com.teslacoilsw.widgetlocker-1.apk and -2.apk and -3.apk and so on.
- If you had installed to /system app, Remove /system/app/com.teslacoilsw.widgetlocker-1.apk (Or whatever name you installed it to /system/app as). You will have to mount the system as r/w just like you did when you installed it this way.
- Remove /data/data/com.teslacoilsw.widgetlocker
- Remove /dbdata/databases/com.teslacoilsw.widgetlocker (if exists)
