Prerequisites:
Procedure:
Verification: Check Device Information again. The firmware version should have changed to the new one (e.g., from B225 to B329).
Once preparations are complete, follow these steps meticulously:
Step 1: Access the Web Interface
Open a browser and navigate to http://192.168.1.1. Log in with the administrator credentials (default is often admin / admin or admin / password—check your device label). huawei lte cpe b593 4g router firmware upgrade
Step 2: Locate the Firmware Upgrade Section
The exact menu path varies slightly by firmware version, but common locations are:
Look for an option labeled “Local Upgrade” or “Manual Upgrade” (as opposed to “Online Upgrade,” which rarely works for older B593 models).
Step 3: Select the Firmware File
Click “Browse” or “Choose File” and select the previously downloaded .bin or .img file. Verify the filename matches your model.
Step 4: Initiate the Upgrade
Click “Upgrade” or “Start.” The router will upload the file, verify its integrity, and begin flashing. A progress bar or status message will appear. Do not refresh the page, close the browser, or power off the router under any circumstances. Prerequisites:
Step 5: Wait for Reboot
The router will automatically reboot once the upgrade completes. This may take 3–5 minutes. The status LEDs will cycle. Wait until the power and internet LEDs stabilize.
Step 6: Post-Upgrade Verification
Reconnect to the router (your IP address may remain the same). Log back into the web interface and navigate to Device Information or Status to confirm the new firmware version is displayed. Perform a factory reset from within the interface (recommended to clear residual old settings), then re-apply your custom settings (Wi-Fi name, password, APN, etc.).
New firmware might change how the SMA ports work. Go to Settings > Antenna and choose:
Test your signal: Settings > Network > Signal Strength. Aim for RSRP > -85 dBm and SINR > 10 dB. Procedure:
Do not use random files from untrusted forums. Preferred sources:
| Source | Link/Note | |--------|------------| | Official Huawei support | Rarely updated for old CPEs | | Carrier support portals | Some telcos (e.g., Telstra, T-Mobile, EE) publish locked firmware | | Tech community archives | 4pda.to, Huawei Firmware Database (search by exact model) | | Huawei CPE Toolbox | Third-party tool with signed firmware collections |
Example filename for B593s-22:
B593s-22_Update_22.200.15.00.00_Macro.bin
⚠️ Avoid “unlock” or “universal” firmware – they often break LTE radio calibration.
