A while ago I picked up a cheapo Sunluxy DVR but quickly discovered that it had a couple of nasty security issues. The device actually worked reasonably well as a DVR so I was keen to try and patch the issues by modifying the OS. Sunluxy didn't offer any firmware updates so modifying an existing update wasn't an option.
Cutting a long story short, I basically ended up breaking the device by manually writing to (apparently the wrong bit of) flash. U-boot is available so there is still a chance to recover the situation if I can find the correct flash image.
