The main board bears the markings "rs-dm-77a" and the main webserver type binary is called 'raysharp_dvr', and only operates in IE using activex and reduced security settings. I'm not certain if you can outright buy it new anymore, as it is very old and out of warranty, but a million new clones pop up each day, all based on the same hi35xx chipset (mine is hi3520 in particular). I've uploaded most of the source files to https://github.com/Hi-Spy/hi352= 0 with exception to the PDFs and binary blobs. The sdk is based around kernel version 2.6.24, so it's quite old, but only has around 10k lines of diff files between it and stock. No, I was in communication with a few people with @hisilicon.com emails that I managed to find on the kernel mailing list (see arch/arm/mach-hisi= ) who eventually pointed me at mobile@huawei.com, but I've yet to recieve a response. In the meanwhile I was trawling the chinese internet for data, and managed to come across someone selling it for 5yuan, which is too cheap to pass up. I don't know how cooperative they are going to be, considering they've been using linux, u-boot, and a host of other GPL'd software without mention or license for at least 5 years, the release date of my particular SoC. --SB9T5IqdS0nfM67pVMaqmuKmB5SsDWifQ-- --w2QV937anJDeUTo89rBSFj7jfVWlpjFIM Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBCAAGBQJXomOaAAoJEHWEtN3AMJGN3AEP/iwz9veYOFHCBftm+2mk/7TN /m2G2MfLTA72hn/cRYlBddG6Pu00NjWZDrby3cHnDF2mvocplMnlk2biuq4/PgXQ 6/H/GV34hRidgaqxe4RUzecEZGsPFh+HmPGccTdNDMxRMxrhNsl8quD/rf1/vUki ne3vj/HGBYre/rP0C8kM2I61err2a+CzKubGDigPSrcDbyjrPsiQY9IRBti11FHq kFHXTIy0CXnUJ0msAet4LJf7CVJck4LIQt89Qux0Kpl2m3fvwbZDOgYC0mOfLtWC 1zIqd8HPNANCs5qWZRA4jxfboGAIMbo1w5cojUjqaj5KbqC+AAJi980djdJ5crba kaAZ/hAEZDe4qcI/PtQiQ1u24HR49l//iMh0BYWUQ3ufaLt8REqtUO4I6HEbShiA O0QEPMm5dfKkkJLyrnvwtXqW8uXz2PkYw32ngmSNVJNqKBTpkVKgRlL/cpdI1R2u MJ783O8fltDLxKr2hSkzwetwioRMqVVbrmeSmSAJLgT/lOMQqDB0x5nuZrqNN1ax iRDHYrElcb5Vxh67oO1ia8emDCcqNkGs35KlHl4ByyFG0fuva08McC2tRKVHT24b MSv1AAE02UuMEnyyUW4uqK4M5abyEXOpESmVPBnwJ8vBDK3aQDiVxf9rtHDM8DXQ 1aS/IRrhtmUPA7zOcujt =Iskf -----END PGP SIGNATURE----- --w2QV937anJDeUTo89rBSFj7jfVWlpjFIM--
