There is file named Hroot.img in the firmware 5.3.0, delte the first 64 bytes of it. Then extract the intrid file from it and you can found there is a comand to run psh before run ash. I was finding a way to inject telnet demone, but failed because of the hroot compress problems.

Thank you my friend, after brick 2 cameras, i think i would rather not to do it by myself. Just share the files, and let smart and professional people do it.

I have to 2 pieces of hikvision ds-2cd2532f-is bought from the aliexpress,it is labeled with 5.2.8,but run 5.2.0 firmware. I will share the mtd5 and mtd6 files on dropbox

Hi Alastair In this way, also need to be careful with checksum?

Is there any tools to analysis the checksum?

It seems a little problem with hikvision ds-2cd2732f-is with 5.2.5. Did i do something incorrect?

The firmware is provided by CBX? i upload it but not works, he has limited the MAC address

why not invite CBX to analysis the programs.
