Hello & Welcome to Just Answer,
Sorry to hear of any issue you are having with your device.
To help you with this issue, let me suggest doing a MASTER RESET of the device, which SHOULD set it back to factory defaults and make the INITIAL screens appear - where you can set the language of the device. I have the instructions to do that below.
To Master Reset the Approach (S1 & S2):===========================- Power the Approach off (Press and hold LIGHT/POWER button until device powers off)- Press and HOLD DOWN- Press and HOLD LIGHT/POWER- Release DOWN and LIGHT/POWER when screen displays Clear user data?- Select Yes
The device should now be reset to default factory settings, and the device should function as expected===========================
Please give that a try and let me know if the initial screens appear.
Thanks, ***** *****
