If you have an official update file provided by your carrier or Huawei, the general process is as follows:

Some debug firmwares allow telnet access. Use at your own risk.
Once you have your current version (e.g., 10.0.3.1), compare it with the latest release listed on Huawei’s regional support page or your carrier’s update portal.
Huawei provides the Suit Tool (Windows) and SD card update method. Only use files with the .bin or .dload extension specifically labeled for E5783B-230.
⚠️ Warning: Wipes settings, may brick if wrong firmware.
