Huawei B880-70v Firmware Update -

A word of caution: Some websites offer “unlocked” or “modified” firmware for the B880-70v that claims to increase LTE speed or remove carrier locks.

Proceed with caution. Flashing firmware carries a degree of risk. If the power goes out during the update or the wrong file is used, the device may become permanently unresponsive ("bricked"). Always verify the file version matches your hardware exactly before proceeding. huawei b880-70v firmware update
