@mohamedeln , med, Found this info. from searching through forums with similar issue as your huawei tablet t1. Hard reset. Take your sim card and memory card from the tab before the reset, battery is fully charged. Personal data from the tab, contacts, pictures, messages, apps. etc., will be deleted if it was not backed up.
Press and hold volume down key and power key for a while, your screen should turn on with option to enter recovery, follow the prompts to enter recovery mode and set the device to factory defaults. Check the link below for tutoral on reset. Good luck.
I hope this helped you out, if so let me know by pressing the helpful button.
