1. Confirm your exact model: Look under the battery. It must say E5573Cs-609. Not E5573s-856, not E5577.
2. Check the current firmware version (via 192.168.8.1). Write it down.
3. Find a match. Search for firmware E5573Cs-609_UPDATE_21.333.01.00.00_Main (example). The numbers must be for your exact hardware version (usually 21.xxx series).
4. Use the official Huawei firmware flasher (Micro-USB to PC, using Samsung USB Drivers + Huawei Firmware Writer).
5. Do not interrupt power during the 5–10 minute flash process.

The next step is to download the appropriate firmware for your device.
