I recently searched for the User Manual for a Huawei Model HG253s V2 Home Gateway. I found
the document which is dated 2015.
Google also found the HG253s V2 open source code.zip file from February 04, 2015 @117MB.
Featuring the Linux kernel version 2.6.30 this file was available from huawei.com
So, based on what I've heard from the CIA, MI6, GCSB and Five-Eyes, I'm now
looking through the source code for the functions that send the messages back to the
mothership in China 😉
...Haven't found any code that does this so far !
In summary. I was surprised that Huawei release their source code. Admittedly it's for
a device that's at least five years old and, for all I know, it may be the same code
that OpenWRT use.
I guess I'll still have to wait a while for the source code for the Huawei 5G
