Dahua IPC EASY unbricking / recovery over TFTP
- Thread starter cor35vet
- Start date
That file is there, I think... Path to this dir: C:\dahua\Dahua_TFTPBackup\root
note that my "install" file is 0 bytes, and that is what threw the error in 7-zip - I went to a different firmware file from Dahua, and that file there seemed to have the order of install - here is the contents from the different FW version (so assuming it won't work for me, but wanted to see what was in one anyway...
{
"Commands" : [
"burn kernel.img kernel",
"burn partition-x.cramfs.img partition",
"burn romfs-x.squashfs.img rootfs",
"burn pd-x.squashfs.img pd",
"burn user-x.squashfs.img user",
"burn custom-x.squashfs.img custom",
"burn web-x.squashfs.img web"
],
"Devices" : [
[ "IPC-HX3XXX", "1.00" ]
],
"Vendor" : "General"
}

It is indeed.
It's not clear (at least to me) why the romfs-x.squashfs.img is inaccessible to the tftp server, yet the upgrade_info ... file is OK.
Just guessing here :
Presumably the .img files are rw as opposed to ro ?
how do I check that? From a Windows FS perspective, they are RW to my account - is that different since the TFTP app is presenting Root up as some sort of share?

Maybe configure what's not allowed to all 'Yes'.
I changed the .ini file to allow write to everything, but same result.. 
But - in looking at your link in your sig, I found someone who ran into issues in a multi-nic machine, and my laptop has a dock, so has 3 nics - 2 wired & 1 wireless. I disabled the 2nd wired & the wireless & tried again... 1 time I got through the first file... but then it timed out, and I never got it to go that far again...
So, I moved the apps (and re-pointed static route) to my NVR box, and tried again from scratch. Still timing out, same errors. I have tried older / different FW versions, but same result. Also, every .img file I have downloaded says it's corrupt, both in WinRar & 7Zip - is that normal?? (It's the "install" file in each of them) - are you able to replicate that by chance?
Please help - I feel like I am close, but not sure what might be wrong! (I disabled Windows Defender as well, just FYI, in case it was causing issues...)
Thank you!
