Unbricking procedure for WLX-652 and NS-K330

READ: This unbricking procedure is intended to work when you have a serial connection AND your NAS enter at least into bootloader. It will rewrite the default stock firmware back to your WLX-652 or NS-K330 NAS. If your NAS is unresponsible with the serial connection, chances are that you will have to rewrite the flash.

To download the files, right-click on the links and use "Save as".

Get a serial interface connected through a RS232-TTL converter. The serial parameters are 38400-N-1. The board have some holes in which the pins can be connected, next to the processor.
Set your computer IP address to 192.168.0.100, and have tftp server running (I do like tftpd32 in Windows or tftpd-hpa in Linux) with the file recovery.8132 in the root directory.
Start the system and interrupt the boot process with any key to get in the "Star Equuleus #" uboot prompt.
Use these commands:

  setenv ipaddr 192.168.0.10
  setenv serverip 192.168.0.100
  tftpboot 0x1000000 recovery.8132
  go 0x1000000

The recovery image should boot. You must be able to use the NAS prompt now.

Download and unpack fw_def_mtd.zip. Copy the files fw_def_mtd1_config.bin , fw_def_mtd2_kernel.bin and fw_def_mtd3_initrd-and-web.bin to an usb drive (prefer fat, ext2 or ext3) and connect it to the NAS. It will mount automatically.
Type the command "mount", to check that the pendrive got mounted on /usb/sda1. We will assume this mount point for the remaining of procedure, change it accordingly, if necessary.
Write the files back to the correct flash partitions with the following commands (the kernel and initrd-web will take some time):

/bin/dd of=/dev/mtdblock1 if=/usb/sda1/fw_def_mtd1_config.bin
/bin/dd of=/dev/mtdblock2 if=/usb/sda1/fw_def_mtd2_kernel.bin
/bin/dd of=/dev/mtdblock3 if=/usb/sda1/fw_def_mtd3_initrd-and-web.bin

Remove and reconnect the power cable. Remember that your NAS will return to the default factory settings.

NOTE: Depending on the working state of your NAS, this procedure may not work. Feel free to ask for info.

The web interface is also available when booting the recovery image. From there it's possible to flash snake os images.

Hi Dear,

My name is Weymar, and i´m from Brazil. I did the procedure, but a message appears. "Retry count exceeded; starting again". Can you help me? I used the circuit http://pinouts.ru/Converters/rs232-TTL_cable_pinout.shtml, Windows Vista, putty (serial) and SolarWinds?_TFTP-Server.

Thanks

My wlx-652 stopped working after upgrade, and its ethernet interface lights(green and orange) is lighting up 2 times when I start device. Then nothing happens. Did my device bricked ? Which way I should try to unbrick it ?

I have arduino mega 2560 device if that helps solving problem.

Fyi if i connect cables from arduino's tx rx ground and 3.3v to wlxkj-652 v1.0 board with 4 holes below star chip, it powers up board without adapter. So I assume i can do something with using tx rx cables(i see they are connected to star chip??).

Any help ?

Hello friends: I have used this procedure succesfuly with my RITMO LN-86BT (from dealextreme). I am running OpenSuse? 12.1, I have used Yast-tftp-server, Minicom and a FT232RL USB to Serial Module (from ebay). I had some problems in the step 4 ("tftpboot 0x1000000 recovery.8132" returns: "T T T T T T", "Retry count exceeded; starting again"). I tried turning off the firewall at ethernet adapter and it worked. My NAS is alive again!!!! Thanks a lot.
