Get PAID $$$$£££ Recovery My Dahua DH-NVR

[Hamyx]

Hi dear All
I'm new here as well to CCTV, first of all thank you all to accept me into this great forum commits.

I got one dahua nvr6000 from friend, and was working fine till I try to up grade firmware, that didn't finish and stack so I reboot the device and the device wont boot any more.

I need help to recovery it or re-flash with similar Firmware or other since it can work, and I can pay for they service. Moreover if someone can provide as well HDD clone image from the same model range or similar device that I can use to recovery it I can pay as well.

Please any one help to install OS on this device even if need to pay for guide or software licence..

Best regards

Hi thanks for reachout,
Definitely this device have small NAND-flash drive in Mainboard where OS are installed, and not on Phisical HDD, I can boot with USB boot tool and see all spec of device

It's x86 platform.
I think bootloader is alive, so.... find COM port and try connect to PC.
Better make MB photo with best quality

2GB image must be on ....

If ypu can boot from USB flash, so load linux and make backup. Use dd

 

[Hamyx]

Yes ITuneDVR
Definitly its a x86 PC_NVR, but I cant boot at all, so unable to com to it please see picture of it and let me know in what you or some one could ehelp.

Any help is apreciate even need to pay for it.

 

[iTuneDVR]

Sorry...
2GB SSD is in NVR608-4K from i dumped some time ago from work one

If your GRUB work, so you need change stringboot to usb linux flash for x86 platform and make full dump from you system, as i said prev.
Use dd command to copy full image!!!

Find in your place smart linux guy or try youself but carefuly!

Why you don't ask help in original Dahua service?

 

[Hamyx]

Hi again ,
thanks for your time and all guide, I try Dahua already, even from the forum they said that the device are already out off warranty also I'm for I contact the reseller. So I had to dig out by myself or pay someone to solve it.
I'm not Linux guys even I'm able to handle it with some guide, so will try replace the bzImage and try it, make a backup of original file first.

Hi again ,

How old?

I'm not Linux guys even I'm able to handle it with some guide, so will try replace the bzImage and try it, make a backup of original file first.

First - backup, next - all other manipulation.
It's not so big problem at all, but need more informanion and skills.
Only firmware and nothing more. All hardware is well!

Of course if device in nand - it's more easy, than ....
The main thing - do not give up!

I am pretty sure that videos recorded on your HDD is still there you can mount it on a PC even if you have Windows (there are a few windows tools that can "mount" ext file system) and you'll see the files.

 

[iTuneDVR]

No need windows and no need video from hdd, only linux usb to boot!
Need pure image and then....

 

[Hamyx]

Sorry dude
How I could do it, which Linux usb tools as well which pure image you mean, is it the firmware?/?
Really sorry for incommode..

 

[iTuneDVR]

You just do not know and do not ask for forgiveness
Any ubuntu, debian, or... revovery usb flash image and try...

 

[Hamyx]

Thank you iTunerDVR
will download ubuntu and try mount HDD and replace this file and test it again, will keep you updated.

Gratefully for all help

God Bless

 

[iTuneDVR]

Be careful!

 

[Hamyx]

OK dude, I will make a copy of original file prior to replace it and test if work if not just put the original back.
I wish if I could have help from other that had similar problem with similar device also if I was good with Linux any way you guide have bee help full and are gave me some knowledge of it.

Have a good night we talk soon.
K regards

 

[iTuneDVR]

OK dude, I will make a copy of original file

Not file.
Whole disk image!

 

[Hamyx]

oopsss I was thinking that is just a file that you provided, as when I mount the NAND-flash from device it split it on 3 partition and this file bzImage on 2 of partition plus other file, so how I will replace whole disk image also with what as already said I was unable to decompress the firmware...

 

[iTuneDVR]

Make backup image and send it to me, then will see
No problem with decompressing, and it maded in 2014

 

[Hamyx]

Hi dude Good Morning
Unable to boot with the image that you provided after replace it the same error persist, and I just replace the original back, also already copy all partition file to upload, will do it later on and keep you informed.

Thank you
