Suggest read the uBoot docs for what is (possibly) available.

a uboot is a preboot that loads the OS
You will need to see if you have an OS on your board to boot into.

I'd try some common commands like

and try see what partitions you have etc

Whats the SoC?

Some of the more modern SoC's can do recovery via USB boot.
If not, you'll need an SPI flasher or similar to rewrite the uboot directly onto the flash, eg with a BusPirate or dedicated device.

I wish I could afford IDA, that was actually moderately useful.

You can't assume/guarantee that the update /upgrade mechanism will be the same for each camera though.

Looks like it loads the file via web interface into ram, writes to /tmp then does some compares to see if valid.
I'd check the .bin file you first gave to see if it passes their compare process.

I grabbed some other files they provide for other cams. One of those files was JFFS, from which I got "update.cgi", but couldn't understand the algoright for it. Anyway, they seem to pack kernel and fs into that binary file. Attached some flowcharts from IDA and original update.cgi

Does someone have the FW of the HW0021? I have seemed to install a wrong FW, and now my cam is all black and white, with very poor resolution. Want to get back to the original FW, but can't find it..:-S.

I downloaded the rar file, unpacked and took a cursory look at the bin file.

Looks like its possibly encrypted or compressed post header, as I don't see many FF's or 00 strings in the file after the initial header.
strings also doesn't show any readable text, which ties in with it being compressed or encrypted.

A scan with binwalk ( ) to see if it finds any recognizable FS or compression in there shows nothing.

I'm guessing its probably encrypted with some custom method.

You'd need more firmware files to look at in order to proceed.

Post 5 messages, and the restriction is lifted,  its a spammer block, unfortunately if you don't make it difficult then the boards get inundated with spam.

I have removed some of the non relevant questions (the ones related to the older forum template).

Firmware / VACRON firmware format

I have this IP camera from, I checked their firmware and couldn't find anything about it. I mean it either encypted or compressed.

Suppose it's possible to unpack/decrypt firmware. Would it be possible to modify the linux inside it and upload it back?
