UnBricked CD-R King CW-5358U CW-5356U

If you happen to bricked your CD-R King CW-5356U / CW-5358U by updating with the wrong Tomato firmware then worry no more that was also happened to me. Here's a quick guide thanks to TipidPC forum credits to the poster and to the contributors.

e-gizmo's USB to UART (Serial TTL) Converter Prolific PL2303 Item Code: 77011931 Php250.00
First of all what you need is "USB to UART (Serial TTL) Converter Prolific PL2303" for only 250 peso you can get it from e-Gizmo for the JTAGging. Second, must have the stock firmware of CW-5356U you can download from here mirror.

You should have a console tool first!!

1. I flash the other tomato firmware from shibby -->tomato-K26USB-1.28.RT-N5x-MIPSR2-084V-BT-VPN_N10U.trx
It seems work , but when I reset (clean nvram), it Bricked !!! I can not get the IP after rebooting!

2. I plug my console tool on the CW-5356U's 4 pin console port and open terminal on windows XP

3. I set my PC Manual IP submask default gateway
(this is because I saw the info on terminal)

4. Turn on the power and keep clicking CTRL-C at the first seconds CW-5356U on
the terminal will show CW-5356U stop at CFE mode

5. I open IE and go to then the screen shows :
Broadcom - CFE miniWeb Server page

6. choose the right file ( I got from CD-R king named "CW-5356U_1214.trx")

7. wait until its done and show
Upload completed. System is goning to reboot. please wait a few moment~

Unbricking the two routers

Unbricking CW-5358u


CW-5358u (Pinout from Left to Right)
Pin 1 - Vcc 3.3V (Don't connect anymore since the router will be powered by the supplied adaptor. You may test as well with a multimeter and you'll get 3.3V)
Pin 2 - GND (Connect to GND on TTL Converter)
Pin 3 - TXD (Router side) to be connected to RXD on UART Converter
Pin 4 - RXD (Router side) to be connected to TXD on UART Converter

Entered Broadcom = CFE miniWeb Server after Ctrl+C (right). Ctrl+C stops router startup.
Please click "Restore default NVRAM values" to ensure proper operation

Thank you very much @Ibrahimovic for the guide at page 2. I hope, images below would help others who have bricked their CD-R King routers.


hi, can you unbrick mine?

do you have a shop?

sure, no problem I can help you. Anything that I can help it for you?

Hi Sir Jonathan, how much it will cost me if you unbrick my CW-5358U. TIA

The cost is too cheap for unbricking your CW-5358U, before you decide to let me fix your device please try to canvas first the cost of shipment as of now I am in my province.

I am also repairing Huawei4G WiMAX wireless modem such as BM622, BM622i, BM625, BM622m and others alike. Please take note that I am not a hacker like others does, I only repair all electronics stuff this will include modem and routers, firmware customization also.

kung wala kang hyperteminal yan ay kasama sa windows, gamit kana lng ng Putty mas madali.

yup.. putty pinaka madali gamitin kesa sa hyperterminal.

sir may firmware dump po ba kayu ng CW-5356U? baka pwede po makahinge.... need ko lang po talaga...

@ Xiugai Macdizhi :

back read ka na lng sa taas nag update ako today para sa stock firmware pede mo ito i-download.

Kuya pede ba i optimized ung speed ng net gamet 2ng CW-5358u? kng alam nio po pede paturo? tnx

@ War Khan :

pwede, but naka depende pa rin sa DSL or sa WiMAX yung connection. pede mo i-limit ang broadcast kung konti na PC lang ang gamit mo.
