Hello bettikler, go to page3, post56. This is exactly the board i have. I installed the firmware with a programmer, that worked.

I would like to share my experience. I think the software transfer is the easiest with the CH341A programmer and SOP8 DIP8 test clip. I spent a lot of time with the other methods. You can read everything in the posts, it's really not hard. The hardware you get cheap at the China-shops.

With usb in the nvr updatesection didn't work! This was the heginning of my problems, See my first post.

Yes, I have taken exactly these file. But how am I supposed to do the update?

:iloveipct: Good news! The system is running again. I did not believe it anymore .... Many thanks for your help!! I've written the flash sw-nd6004-h1-2.0-128M from V1.0.1.5927 and it worked. This file does not exist in the V1.0.1.6964, is that the reason why the update did not work?

I have now written all 4 files individually, without success. The programmer does not give an error message verify is ok. I think the file I need is composed of the individual. Serial I get no answer. As I said the led does not light up that means the board has no bootloader, I think.

No, I did not decode the firmware. Unfortunately, I do not know how to do that. Verify failed! chip with the contents are in disagreement! What can I do now?

There is another problem. the red led next to the main cpu no longer lights, I think the bootloader is no longer available. I have both files written without success.

That is right, but there are three .bin files in the archive!

So, I am back... I have now received the programmer and the clip. The software is installed and the chip is recognized. Which firmware do I have to flash now?

OK, then i will buy a CH341A programmer and an SOP8 DIP8 test clip at a chinese shop.

I have clean it, here ist the part number: 25L12835F M2I-10G 8C286500 L161504

The numbers are verry smal, what i can see, on the chip bottom right: 25L12...... M2I-1... 80286... L16...... chip top right ....09 402... 3 chips on the left with the same numbers FR9886 G1608 L849D

Let's try it.... I have seen these devices in many onlineshops. First i post a photo from the nvr board.

No, no problem, I wanted it that way, you made a lot of effort. Thank you for the help and know. I think I learned a lot about tftp and other.

I tried sf probe 0 tftp 0x81000000 firmware.bin sf erase 0x0 0x1000000 sf write 0x81000000 0x0 0x1000000 without success, now the systen does't boot anymore. I think I will get a new board.

The tftp download seems to be ok, after that JUpdate did't load.... JUpdate 0x1000000 0x80008000 I try it too, same screen.

No, what must i do when the download is finnished? I tried JUpdate 0x1000000 0x81000000 and Jupdate 1000000 0x81000000 and JUpdate 16777216 0x8100000 without booting screen.

tftpboot is an unknown command, the the other 2 commandline also. With tftp 0x81000000 firmware.bin the download starts!!

I can't dowload the file with JUpdate. on screen: hisilicon # JUpdate 0x1000000 0x81000000 JUpdate Ver2.0 for JVS-D8008... JUpdate 16777216 0x81000000 With this line it's the same. After this nothing goes on. My tftp server is running, when i make tftp upload it is running but at adress...

I'am back in 2 hours, see you later! Thanks

@KyleRiemen Have you any idea of the correct commandline?

So, this time i have a running tftp server, but JUpdate wan't this parameters: JUpdate (filesize) (temp ram adress)
