How to restore a FS 613A M136

Also works for Foscam FI8908W

* Caution: With this modifications the ip camera lose the warranty and this is not guaranteed to work for all ip cameras. I’m not responsible of a bad use of this manual, take care with all, cables, voltage, to weld ….

These IP Cameras are very similar like Foscam FI8908W and the firmware is different than you have in your Foscam. If you update this ip camera with the last FI8908W firmware, it will restart every 20 seconds and impossible reset the firmware. To solve this problem is noy easy, but is possible.

FS 613A M136:


In a small sticker indicate the model (FS 613A M136), this ip camera is a clon form EasyN Technology Co. Ltd company ( There are differents models of ip cameras, all of them are very similar like Foscam models. The webpage does not actually provides their respective firmware.

Device Firmware Version: lr_cmos_4_11_2_15

Device Embeded Web UI Version: aw_4_3_3_39

The FI8908W (Foscam/Green) and the FS 613A M136 (EasyN/Blue) PCBs are the same:

What we need to restore?

We need to conect the ip camera with the computer (caution: the ip camera works with 3.3V), I use an USB to serial TTL UART, it costs arround $6 AUD on ebay.

Now conect the pins with our FS 613A M136, but carefull, you need to cross RX with TX and TX with RX!!!

USB to Serial IP Camera

3.3V ————- 3.3v

TX ————— RX

RX ————— TX

Gnd ————– Gnd

Look 4 pins: inorder 3.3V, Gnd, TX, RX (remember to cross TX and RX)

Follow the cables : Look for marks on the PCB, above cable connections may be incorrect. Trust the markings on the PCB.

Next step is upload the linux.bin and romfs_cmos_11_14_1_37.img file to the ip camera.

Conect you your USB at the computer, and start the Hyperterminal with this configuration:

Conecting ussing: COM1 (select your default port)

Bits per second: 115200

Data bits: 8

Parity: None

Stop bits: 1

Flow control: None

Open the connection

Power on your ip camera (conect the power supply), Hyperterminal starts to show letters and press ESC

Now we can delete the memory of the ip camera. Write:

First => bootloader> del 6 (press enter and wait to finish)

Second => bootloader> del 7 (press enterand wait to finish)

And then we can upload the files roms.img and (linux_romfs_files) and write with carefully:

bootloader> fx 7 0x7f020000 0×8000 -acxz (press enter)

Select: “Transfer -> Send file” or right click with the mouse and “Send”, in a File browser choose the file with xmodem protocol

Repeat with next file:

bootloader> fx 6 romfs.img 0x7f0d0000 0x7f0d0000 -a (press enter)

At end input: booloader> boot (press enter)

Now you can disconect the cables and conect the ip camera to lan to upload the firmware.

To upload the firmware, download and install the program IPCamSetup

Finally, you can configure your ip camera

If the files roms.img and don’t work or does not update, you can try with Foscam files donwload foscam_linux_romfs_files.
