# Never ever Flash Phone with any file other than its own backup file.
# If the phone is restarting even without sim card inside, then mostly its a hardware problem.
# If phone is not connecting or giving any sort or compatibility error,
then please make screenshot, read full flash and send it to support@et-box.net
# As Clearly Said Above this is a Beta edition and may cause damages to your phone. So Please use at your own risk.
