You make no sense.cant i keep the app at least?
You want to get rid of it but you want to keep it?
If you want to keep the eshop icon on Gridlauncher then don't do anything.
If you want to be rid of it then delete the eshop.xml and eshop.smdh. This does not delete the eshop from your 3ds. This just removes the shop spoof.
If you are talking about keeping the Gridlauncher then removing the eshop items does not mess with it.
If you are experiencing problems with the Gridlauncher then download the Boot File and the updated updater and replace those files on your SD card.
