"Hello @Hacer_El_Bien. is this the procedure you did?
""Dear Flasher, thank you for contacting Flash support. Please kindly note that resetting the phone will erase all of your personal data from internal phone storage, including your accounts, downloaded application, setting etc. There are 2 ways to reset your phone.
1. When your phone can power on normally, Touch Settings -> Backup and reset -> Factory data reset -> RESET PHONE.
2. When your phone can't be powered on, you can perform a factory data reset via below:
1) Long press “power” key + “volume up” key, enter the Data Format interface.
2) Press “VolumeUp” key to select “recovery mode”, press “Volume Down” key to confirm.""
Make sure that your Flash is fully charge when doing hard reset. That is to avoid the interruption while the system is processing the selected option you needed to be done. If in case the issue is still unresolved, the nearest service center in your area is in SM Southmall.
SM Southmall, Alabang Zapote Rd.
Almanza Uno, LasPiñas City
Mon.to Sun. 10am to 9pm
