If you share exactly what you’re trying to achieve (e.g., “Use a different carrier” or “Change band settings”), I can give you precise, safe steps.
To unlock your Huawei E5336Bs-2 and make it portable (usable with any SIM card), you typically need to update or "flash" its firmware to a version that removes the network lock. Prerequisites Before starting, ensure you have: A USB data cable to connect the device to your PC.
Huawei Drivers installed so your computer recognizes the device in "Download Mode." The IMEI number of your device (found under the battery). Steps to Unlock the Firmware
Download Firmware & Tools: You will need a "Universal" or "Modded" firmware file (often ending in .bin or .exe) and a tool like Huawei Flasher or Balong USB Downloader.
Enter Download Mode: Connect the device to your PC. If the update tool doesn't detect it, you may need to perform a "boot shot" (short-circuiting specific points on the motherboard) or use a "force download" key combination.
Calculate Flash Code: Many firmware updates require a "Flash Code" or "Password." You can generate this using an online Huawei Unlock Code Calculator by entering your IMEI. Run the Update: Open the firmware update file (.exe). Enter the Flash Code when prompted.
Wait for the "Update Successful" message. Do not disconnect the device during this process, as it can "brick" the router.
Change WebUI (Optional): If you want a cleaner interface or more features (like USSD or signal monitoring), you can flash a separate WebUI file after the firmware update. Important Warnings
Warranty: Flashing third-party or modded firmware will void your warranty.
Risk: If the power is interrupted or the wrong firmware version is used (e.g., E5336 instead of E5336Bs-2), the device may stop working permanently. e5336bs2 unlock firmware portable
Legal: Ensure that unlocking your device complies with your local telecommunications laws.
Unlocking the Huawei E5336Bs-2 to accept all SIM cards typically involves either entering a network unlock code or flashing a "universal" firmware that removes provider restrictions. Quick Unlock Method (Code Based)
The most common way to unlock this device without changing the firmware is via an unlock code (NCK). This is often preferred because it avoids the risk of "bricking" the device with incorrect software.
Obtain IMEI: Look under the battery or enter 192.168.8.1 in your browser and check Advanced > System > Device Information.
Generate Code: Use a calculator like HUAWEI_Calculator.exe (v201 or New Algo) or an online service.
Insert New SIM: Put a SIM card from a different network into the device.
Enter Code: Access the web interface at http://192.168.8.1. A "SIMLOCK" prompt should appear; enter your generated code. Firmware Flashing Method
Flashing is used if the device is "hard-locked" (0 attempts left) or if you want custom features like band selection or IMEI editing.
Firmware Files: Look for "universal" or "modded" versions, often found in repositories like Huawei-LTE-routers-mods on GitHub. If you share exactly what you’re trying to achieve (e
USB Loader: You may need specific loader files, such as E5336BS_E5_usbloader.bin, to allow the device to accept new firmware over a USB connection.
Balong Tool: Advanced users often use Balong USB Downloader to push firmware to the device while it is in "boot" or "test point" mode. Essential Tools & Resources HUAWEI Hisuite Free Download | HUAWEI Support Global

The e5336bs2 is a 4G Cat4 device – max 150 Mbps. In 2025, 5G hotspots are common. However, for IoT projects, emergency travel, or as a backup router, the e5336bs2 has unbeatable battery life and USB tethering features that modern 5G modems lack.
Unlocking it extends its life by years. And because the unlock is at firmware level, you can even resell it as "unlocked portable hotspot."
Use DC-Unlocker or AT commands (AT^SYSCFGEX=...) to lock the modem to specific 4G bands (e.g., Band 3, Band 20 for Europe). This improves signal stability.
Legality – Unlocking carrier-locked devices may be legal in some regions (e.g., EU, US after certain conditions), but modifying firmware may not be.
