Hi, 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 at... https://consumer-tkb.huawei.com/weknow/servlet/download/public?contextNo=S16... 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 routers. cheers, Ian.
