hi guys
Help me please!
I bought my camera here http://www.ebay.co.uk/itm/140995053856?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
I mistakenly flashed the firmware from another camera http://www.wansview.com/index.php/h-264-ip-camera/708-ncz-625w
The camera works, but the web interface does not work, asks for a password and username at the entrance, but then everything in 404 pages.
I want to restore the firmware via tftp.
Please help me find rs-232 connector on the PCB.

hey, is there any way to change the MAC adress of a EasyN FS-613B-M1661 camera? Mine is working fine after recovery, but i have 2 cameras with the same MAC adresses and its creating issues.

Hello,

i was trying to update my Tenvis 3815W/TR3818 (i think its a Foscam US8908w clone) but it just did brick my cam.
The only hope i have right now, is to fix the cam with a firmware recovery but i cant find the right pins for the serial connection.

Here is a picture of the PCB, i hope someone could help me to find the right pins.

I've put red rectangle around serial connector on your board:

To enter uboot you need to press 4 when asked.

Hi, i have bricked my Tenvis 3815W on a bad update, i have the same PCB of TomThedragon (thx to yuri for details about jtag) but now im not sure at 100% about what file i need to upload to my cam for bring back it to life and not to make more troubles... someone could help me? thx in advence! and sorry for my poor english

Big thx to Yuri for the help with the pins and sorry for my late answer, i was quite busy..

Okay i could get a connection over the native COM port of my computer with help of an serial2ttl adapter but i got stuck shortly after that, because my cam seems to use a different software :/

Here is a log of the console if i let the cam boot:

Hi, and thx for the awesome information...

I have a question regarding to my Foscam China clone. I accidentally updated a wrong webui file and now the hexcode in memory is wrong, so my webgui doesnt work anymore. The bootloader and romfs works as normal, but crashes because of the damaged webui file.

This is the wrong hexcode:

bootloader > d 0x7F1FFFFF

Displaying memory at 0x7F1FFFFF

[7F1FFFFC]          440C9ABD - 04F0A6D8 000CF370     ....D....p...

[7F20000C] 020A0402 0000000F - 63617069 6E692F6B  ........ipack/in

[7F20001C] 2E786564 016D7468 - 0000021E 3CBFBBEF  dex.htm........<

--> as you can see ipack/ -> is wrong ... I tried to override the memory with MX command and original webui firmware, but it didnt work.

Any ideas how to solve this?

Thx and regards!

you should try to flash the correct webui via the camera finder tool that should have come with your cam. It usually locates your cam in your network and with a rightclick it offers to flash new firmware

second method: try to erase the webui partition and flash it with fx command

March 31, 2015, 03:47:55 am
hi,
camera.sh crashes while loading, so I have no connection to the cam via network.
BUT finally I got it working with fx command, also tried memset and e, but they didnt change the memory?!?
In my case I have no additional partition for webgui, so I dont know how to erase it? But I have overridden the memory via fx and it worked like a charm.
The start address of webgui is 0x7F200000 and I just uploaded the new webgui.bin file via:

fx 5 webgui.bin 0x7F200000 0x7F200000 -a -nofooter

so thx for the hint schufti

Hi everybody,

this is my first post in OpenIPCam forum!

I'm trying to make a backup of my camera's firmware before starting to play with other firmware, but I'm stuck in the Kermit phase and maybe someone can help me.

I'm able to see the bootloader prompt on the terminal. Then I close the terminal and open the same connection in Kermit (Kermit 95 in Windows 7). I make the connection, but can't send commands, like for example 'ls -la' to test.
I think this may be the reason why when I run the script it gives me that it can't find the bootloader prompt.

It seems the Kermit when in terminal mode don't sends commands, but if I reboot the camera I get all the startup information so the Kermit config connection is OK, but somehow the "keyboard" is not working.
Can someone give me some tips on what it might be the issue.

Thanks,
Paulo

as far as I remember there were some statements that the free Windows version doesn't work, but the trialversion of the commercial kermit will. YMMV

Thanks for the quick reply, I have the version which has 21 days free trial, but I'll check more in detail if there can be some problem with it.

Thanks,
Paulo
