<p>I wanted to try and lock it to 1800Mhz, but there's no option for that exposed in the GUI that I can find.</p>

<p>Generally few devices allow for that. I do know the Zyxel devices we use allow for that in the engineering version we have for lab purposes. I'm not sure what is available in the commercial version. I do know however that we completely lock down the local

<div>The datalock algorithm has been broken and is available through some of those sketchy sites. After that Huawei updated their algorithm. I do believe it follows device, not sw. So if your B818 was produced before the change you can use those sites.
Spin up a VM or something to try them out.</div>

<div>The proper procedure it to contact Huawei and get them to give you the code. I believe it is intended only for trusted partners, but you can give it a shot to try and reach out to them.</div>
