OEM easy installation

The easiest way is to enter the recovery mode as described in brnboot Instead on what is documented on that page, for this model the recovery web interface is available on http://192.168.2.254/

Additionally the page request for a PIN code which is still unknown… This PIN-code is also SHA-1 hashed and compared, I have no idea about constraints, the hash as taken from the disassembly is: B16D0EF3 DD0632DC D13D135E 02A097AE C4044C24

The bootloader's serial console is another option, but there is a SHA-1 hashed password as well. The only remaining way to flash it, would be to use JTAG…

I have managed to patch the password protection code sequence out, so I am able to gain access to the bootloader menu. The loader itself won't let you erase or overwrite the first sectors so it is useless for flashing another bootloader.

Administrator mode is aquired by pressing '!' Sniffing around through the bootloader disassembly shows some differences, these are explained in the last column

The VR9 bootloader has the following menu options:

Menu item Admin mode? comments

Upgrading OpenWrt

generic.sysupgrade

FIXME - haven't installed OpenWRT yet, so no updated instructions

If you have already installed OpenWrt and like to reflash for e.g. upgrading to a new OpenWrt version you can upgrade using the mtd command line tool. It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.

LuCI Web Upgrade Process

Terminal Upgrade Process

  • Login as root via SSH on 192.168.1.1
  • Use the following commands to upgrade.

cd /tmp/
wget http://http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
sysupgrade /tmp/xxx.abc

  • If sysupgrade does not support this router, use the following commands.

cd /tmp/
wget http://http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc
mtd write /tmp/xxx.abc linux && reboot

Basic configuration

Basic configuration After flashing, proceed with this.
Set up your Internet connection, configure wireless, configure USB port, etc.

Specific Configuration

Interfaces

The default network configuration is:

Interface Name Description Default configuration
br-lan LAN & WiFi 192.168.1.1/24
vlan0 (eth0.0) LAN ports (1 to 4) None
vlan1 (eth0.1) WAN port DHCP
wl0 WiFi Disabled

Switch Ports (for VLANs)

Numbers 0-3 are Ports 1-4 as labeled on the unit, number 4 is the Internet (WAN) on the unit, 5 is the internal connection to the router itself. Don't be fooled: Port 1 on the unit is number 3 when configuring VLANs. vlan0 = eth0.0, vlan1 = eth0.1 and so on.

Port Switch port
Internet (WAN) 4
LAN 1 3
LAN 2 2
LAN 3 1
LAN 4 0

Failsafe mode

Front:

Back:

* Note that in this pictures the casing was placed on top of the PCB, not fitting the connectors (as the jtag cables were still attached)

Opening the case

Note: This will void your warranty!

  • To remove the cover:
  • 1) peel off the 2 rubber pads, remove the screws beneath.
  • 2) Take care when removing the front from the back plate, as there are 3 'clips' along the top, 2 at each side and 1 at the bottom center to hold the front and back of the casing.

Main PCB

I had to solder the 14 pins EJTAG header, but the location is quite clear

EJTAG header and serial port header (4pins), 1st pin is at the right side (Pin 1 marking is located at the other side of the pin)

Both flash chips are located at the bottom of the PCB

Important components

The actual VRX288 version is important because of the internal ethernet PHY firmware, mine is a V1.1

There are 3 external ethernet PHY chips available (these are V1.3)

Serial

port.serial general information about the serial port, serial port cable, etc.

Pin 1 is on the right, marked with a white arrow on the PCB, so the pin numbers are counted from right to left. The voltage is 3.3V. Please do *not* connect the VCC pin of the PCB to the VCC pin of you serial interface as this may destroy both of the devices. The pinout is as follows:

Pin number 4 3 2 1
Function GND RX TX VCC (3.3V)

Hooking up to the serial with 115200/8N1 enables you to access the bootloader. You have to enter three spaces immediately after powerup after which you have to enter some secret password (seems to be 16 characters, but of course I have no idea what it would be… The SHA-1 hash for the password is: 42f25cd06c3e1d7096b35cbd3c3813c23adaf03a

Debricking

Bootloader Mods

  1. you could read about bootloader in general

I have patched out the password protection to gain access to the bootloader's menu, There aren't really interesting things to do there, so I flashed it over with u-boot.

Hardware mods

  1. as a beginner, you really should inform yourself about soldering in general and then obtain some practical experience!

I had to solder the JTAG header on the board

Notes

SIP:

daemon to test: sofia-sip pjsip(already in openwrt) owsip(already in openwrt)

driver vmmc: http://mirror2.openwrt.org/sources/drv_vmmc-1.9.0.tar.bz2 drv_vmmc-1.9.0/FEATURES_and_OPEN_ISSUES * TAPI 3.13.0.2, drv_vmmc 1.9.0.3, KPI 2.2.0.0, MPS 2.2.2.5 * XWAY VRX288 VoIP Firmware 2.1.0.7.0 Original firmware 1.9.0.4

need firmware dump for dsl, voip and coef + populate openwrt/package/ifx-vmmc/Makefile

driver tapi: http://mirror2.openwrt.org/sources/drv_tapi-3.13.0.tar.bz2 Same level as original firmware

http://dev.phrozen.org/ltq-mirror/ (dsl and other stuff)

DSL: available version 4.11.4 - my firmware version: 4.12.4 - May works need firmware dump

SWITCH: look at switch_utils note at http://wiki.openwrt.org/toh/tp-link/td-w8970#switch_utility we need to decompile original firmware and recovery switch initialization params
