Lost password of wifi endoscope cam
(1/3) > >>
diy3d:
Hi,

I bought myself a Wifi endoscope camera. The main module is a Wi-Fi accesspoint and with an App, the images can be received on your phone. I was satisfied this device was working well until I changed the default wifi password.  Yes I lost it, I can not remember it anymore. I tried to reset the device so I could use the default 12345678 password...but no way :-\ I asked the the supplier, searched the internet, tried the reset button in all possible combination with the powerbutton, I tried make a USB connect with Putty, I removed the wifi and memory module from the power pcb .. no success. |O
I guess the Wi-Fi configuration and password stored in the program memory of the Ralink RT5350.

So the big question, how do I reset the device?

Therefore, I decided to investigate the device further.

Wifi Endoscoop Module: ZCF99
Os: Linux 2.6.32
Port: 23 tcp open telnet BusyBox telnetd 

WiFi module: Ralink RT5350
Memory module: Etrontech EM63A165TS-6G 16M X 16 Bit Synchronous DRAM (SDRAM)
Serial interface: Macronix  MX25L3206E

Attached pictures show the various components.

Kind Regards

How did you change the password originally?
joao2004:
Have you tried password 88888888 ?

Take a deep look inside yourself and ask if maybe it's worth it just to get a new one...?  Yes, there's a joke there somewhere.

With a RT5350, what you have is basically a little router that think's it's a camera.

Compare something like this: https://wiki.openwrt.org/toh/hootoo/tripmate-nano

Password will be in the SPI flash, yes.  But likely holding down the reset button for a while will get it to wipe the writable overlay partition and revert to the underlying read only state - typically that's a jffs2 near the end that mounts over the top of a squashfs filling the middle of the chip.

Or look for a UART hearder and see if you can get into U-Boot.

Or hold the CPU in reset and have at the flash with some other access device and micrograbber leads - though do pay attention to the designed voltage.
