Unlock H155-381 Router

Job ID: 40177161

Budget: $750 – $1,500 USD

I have an h155-381 “brovi” router that is locked to a single carrier. I have confirmed the hardware supports unlocking, but I still need the correct firmware and the precise flashing procedure to free it for use on any network.

What I need from you is simple:
• Locate or supply the exact, trusted firmware or code required to remove the carrier lock.
• Guide me—step by step—through the flashing process (remote session, scripted tool, or clear written instructions are all fine).
• Verify that, once complete, the router accepts any SIM and all services (LTE, Wi-Fi, VoIP) remain fully functional.

I do not yet have the firmware files, so sourcing them is part of the job. If special utilities such as ADB, Fastboot, Huawei HiSuite, or proprietary unlock tools are necessary, let me know up front so I can have my computer ready.

I will test the router on at least two different networks before releasing payment. Feel free to share any past experience with this exact model.
