Caution: WPA3 WILL NOT WORK ON THESE DEVICES in 21.02.0 if you select WPA3, wireless will error out and not work.
See: https://forum.openwrt.org/t/kirkwood-linksys-ea4500-openwrt-21-02-0-rc1-wifi-problems/95739/11 for more details.
Caution: The wireless seems to have problems with WiFi-stability on connections to certain client chipsets, e.g. Apple-devices.
See this thread on OpenWrt developers forum.
(#1) If it fails to boot showing solid logo only, it's likely too hot. Try placing in a freezer for 3-5 minutes. It works.

Installation
For the installation guide for EA4500 v3, please go to its own page.
The EA4500 has a dual firmware layout: working and backup partitions. It boots from the working partition in normal operation. Firmware flashes occur on the backup partition and the EA4500 shall reboot from the backup partition following from a firmware flash. The backup partition becomes the new working partition when the reboot was successful. The former working partition becomes the new backup partition.
Note: No need for a 30/30/30 reset on this device. In the event of a bad flash, the router shall obviously fail to reboot but don't despair. After three consecutive failed reboots, the router then reverts back to its former working partition and boots normally. Based on this understanding, both EA4500 and E4200 v2 shall always have a partition with a working firmware.
Recent trunk builds (recommended)
As of r47458 both EA4500 and E4200 v2 are supported EXCEPT FOR WPA3, WPA3 WILL NOT WORK ON THESE DEVICES. These boards are identified by the codename “Viper.” The factory.bin image can be flashed directly from the Linksys web interface. Upgrading between OpenWrt images is accomplished with the sysupgrade.tar image.
Prebuilt trunk snapshots offer the most straightforward installation and they are available now: https://downloads.openwrt.org/snapshots/trunk/kirkwood/generic/
← Installing openwrt-kirkwood-linksys-viper-squashfs-factory.bin from the Linksys classic web interface
← Installing openwrt-kirkwood-linksys-viper-squashfs-factory.bin from the Linksys cloud web interface
Upgrading from Candyhouse Chaos Calmer
Unfortunately there is no sysupgrade support (not a defect) on Chaos Calmer builds hence do not open a ticket. Flash back to stock Linksys firmware first before installing current trunk builds. See ForumSee Candyhouse comment
If you prefer building the firmware yourself
Build with:
- Target System → “Marvell Kirkwood”
- Target Profile → “Generic” or “Linksys E4200v2 / EA4500 (Viper)”
- Target Images → squashfs
This will produce the images:
openwrt-kirkwood-linksys-viper-squashfs-factory.bin openwrt-kirkwood-linksys-viper-squashfs-sysupgrade.tar
Custom builds managed by individuals in the community
None so please feel free to start one.
Older builds (deprecated): Installation using Serial
There is currently no way to get OpenWrt onto EA4500 other than using serial console (it is perhaps possible using tftp server in bootloader). How to get that connected you can read later on in this text.
Also, in current https://downloads.openwrt.org/snapshots/trunk/kirkwood/ there are no images for EA4500. So just git clone openwrt repo and compile the images for EA4500 yourself.
In menuconfig you select:
- Target System → Marvell Kirkwood
- Target Profile → Linksys EA4500
- Target Images → ramdisk, ubifs (you need both for installation)
Now you “make” it and expose following files:
- openwrt-kirkwood-ea4500-uImage-initramfs via tftp
- openwrt-kirkwood-ea4500-uImage via http
- openwrt-kirkwood-ea4500-rootfs.ubi via http
Connect to EA4500 via serial console and power it on. Break u-boot pressing any key during startup. Run “printenv” and adjust your ip and tftp server ip if needed. Then boot initramfs:
Viper>> tftpboot ${loadaddr} openwrt-kirkwood-ea4500-uImage-initramfs; setenv bootargs $(console) root=/dev/ram rw; bootm ${loadaddr}
Now in booted OpenWrt, we need to flash OpenWrt into NAND. You need to get the network working first. Then you do:
# cd /tmp # wget http://yourserver/openwrt-kirkwood-ea4500-rootfs.ubi # wget http://yourserver/openwrt-kirkwood-ea4500-uImage # ubiformat /dev/mtd3 # ubiformat /dev/mtd3 -f openwrt-kirkwood-ea4500-rootfs.ubi # mtd erase kernel # mtd write openwrt-kirkwood-ea4500-uImage kernel
After this you reboot the device, break u-boot again and set u-boot to boot OpenWrt from NAND:
Viper>> setenv owrt_bootargs_root ubi.mtd=3 root=ubi0:rootfs rootfstype=ubifs rw
Viper>> setenv owrt_boot nand read.e \${loadaddr} 0x200000 0x200000 \; setenv bootargs \$(console) \$(owrt_bootargs_root) \; bootm \${loadaddr}
Viper>> setenv bootcmd run owrt_boot
Viper>> setenv auto_recovery no
Viper>> saveenv
Older builds (deprecated): Installation without Serial
There is another way to Flash your device, without using a serial connection.
Prepare:
- get the right Image for Your device from Candyhouse Projekt (deprecated)
- build an initramfs image from openwrts buildroot or download mine from Here
- download openwrt-kirkwood-ea4500-rootfs.ubi and openwrt-kirkwood-ea4500-uImage from Here
- format an usb pendrive with ext3 (no idea if fat is working? fatload available in uboot?) and mount it. (if it wont work, use ext2)
- Put uImage, openwrt-kirkwood-ea4500-rootfs.ubi and openwrt-kirkwood-ea4500-uImage on that usb stick. Cleanly unmount it !!!
The flashing process:
- Flash Your ea4500 wit the candyhouse image.
- after reboot candyhouses openwrt will be up, login using telnet/ssh
- plugin the prepared pen drive and run the following commands:
fw_setenv bootcmd 'run owrt_usb; run nandboot'
fw_setenv owrt_usb 'usb start; sleep 5;ext2load usb 0:1 ${loadaddr} /uImage; setenv bootargs $(console) $(mtdparts) root=/dev/ram rw; bootm ${loadaddr}'
mkdir /sda1 && mount /dev/sda1 /sda1 (no mistake it does not boot without it)
reboot
- After a few, openwrt initramfs will be boot from this pen drive. Login using telnet/ssh and rum Commands:
mkdir /sda1 && mount /dev/sda1 /sda1 && cd /sda1 ubiformat /dev/mtd3 && ubiformat /dev/mtd3 -f openwrt-kirkwood-ea4500-rootfs.ubi
- Only if ubiformat and mount didn't produce any errors continue with: (otherwise youre fucked!!)
mtd erase kernel
mtd write openwrt-kirkwood-ea4500-uImage kernel
fw_setenv bootcmd 'run owrt_usb; run owrt_boot'
fw_setenv owrt_usb 'usb start; sleep 5;ext2load usb 0:1 ${loadaddr} /uImage; setenv bootargs $(console) root=/dev/ram rw; bootm ${loadaddr}'
fw_setenv owrt_boot 'nand read.e ${loadaddr} 0x200000 0x200000; setenv bootargs $(console) ubi.mtd=3 root=ubi0:rootfs rootfstype=ubifs rw; bootm ${loadaddr}'
fw_setenv auto_recovery no
reboot
- Now you are done. With the usb stick connected and uImage on it, the router will boot this image. otherwise it boots from nand.
- Have fun!
Flash Layout
The stock layout for E4200v2 (bootlog from paklids):
| Offset start | Offset end | Size | Name | Comment |
|---|---|---|---|---|
| 0x0 | 0x80000 | 0x80000 | uboot | |
| 0x80000 | 0xa0000 | 0x20000 | u_env | |
| 0xa0000 | 0xc0000 | 0x20000 | s_env | |
| 0x200000 | 0x1c00000 | 0x1a00000 | kernel | Overlaps rootfs |
| 0x4a0000 | 0x1c00000 | 0x1760000 | rootfs | Overlapped by kernel |
| 0x1c00000 | 0x3600000 | 0x1a00000 | alt_kernel | Overlaps alt_rootfs |
| 0x1ea0000 | 0x3600000 | 0x1760000 | alt_rootfs | Overlapped by alt_kernel |
| 0x3600000 | 0x8000000 | 0x4a00000 | syscfg |
The stock layout (of the 128MiB flash chip):
| Offset | Size | Name |
|---|---|---|
| 0x0 | 0x80000 | uboot |
| 0x80000 | 0x4000 | u_env |
| 0x84000 | 0x4000 | s_env |
| 0x200000 | 0x1a00000 | kernel |
| 0x200000 | 0x1a00000 | rootfs |
| 0x1c00000 | 0x1a00000 | alt_kernel |
| 0x1c00000 | 0x1a00000 | alt_rootfs |
| 0x3600000 | 0x4a00000 | syscfg |
A recommended layout for OpenWrt is to specify the kernel and rootfs settings, leaving everything else alone so as to remain compatible with the stock firmware.
| Offset | Size | Name |
|---|---|---|
| 0x0 | 0x80000 | uboot |
| 0x80000 | 0x4000 | u_env |
| 0x200000 | 0x200000 | kernel |
| 0x400000 | 1c00000 | rootfs |
Back to the original stock firmware
Caution: Going back to the original stock firmware is impossible directly via OpenWrt (versions >=18.06). Therefore, you should always flash from the working Linksys partition only if you want to be able to skip the following steps. See Forum
SSH method (OpenWrt >=18.06 and LEDE 17.01)
Probably the most generic way to go back to the stock firmware. You can skip the downgrade to LEDE 17.01 if you already are running it.
- On your workstation computer:
- Download LEDE 17.01.4 firmware image
- For the E4200v2
- Extract the file
FW_E4200v2_2.1.41.164606.imgfrom this archive on your workstation
- For the EA4500
- Extract the file
FW_EA4500_2.1.41.164606.imgfrom this archive on your workstation
- Connect the workstation using a cabled connection to the router and ensure that your workstation is configured as DHCP client
- Downgrade to LEDE:
- On your workstation using SCP, copy
lede-17.01.4-kirkwood-linksys-viper-squashfs-sysupgrade.tarto /tmp on your router - On your router using SSH, issue the command
sysupgrade -F -n /tmp/lede-17.01.4-kirkwood-linksys-viper-squashfs-sysupgrade.tar - After a while, your router should reboot on LEDE 17.01.4
- Revert to factory:
- For the E4200v2
- On your workstation using SCP, copy
FW_E4200v2_2.1.41.164606.imgto /tmp on your router - On your router using SSH, issue the command
sysupgrade -F -n /tmp/FW_E4200v2_2.1.41.164606.img- Do not use the zip archive directly, you have to extract the firmware image from it first
- For the EA4500
- On your workstation using SCP, copy
FW_EA4500_2.1.41.164606.imgto /tmp on your router - On your router using SSH, issue the command
sysupgrade -F -n /tmp/FW_EA4500_2.1.41.164606.img- Do not use the zip archive directly, you have to extract the firmware image from it first
- After a while, your router should reboot on the stock Linksys firmware
GUI method (LEDE 17.01 only!)
You could try to flash a Linksys firmware image (extracted from zip) directly from the LuCI web interface.
Do not use the zip archive directly, you have to extract the firmware image from it first

Cut the power method
This works too if you had flashed a firmware image from the stock Linksys web interface and you've not done another subsequent upgrade from OpenWrt.
Cut the power to the router while the router is booting up. The router white LED shall blink rapidly and that's when you cut the power--inducing a failed boot. After 3 failed boots, the EA4500 then boots from the backup partition and reverts back to its Linksys firmware. See Forum

Opening the case
Note: This will void your warranty!
http://kelvyntaylor.blogspot.cz/2012/07/how-to-open-cisco-linksys-ea4500-router.html
There are 4 screws on the bottom of the case, hidden under 4 glued-on rubber feet parts. Pry off the rubber feet with a small screwdriver and remove the screws, then simply pull the top off.
Serial
→ port.serial general information about the serial port, serial port cable, etc.
The serial port is located at J5.
| PIN | ID |
|---|---|
| 1 | Vcc 3.3V |
| 2 | |
| 3 | RX |
| 4 | |
| 5 | TX |
| 6 | GND |
Pin number 1 is the one next to the annoying white led. The TX pin on the board should be connected to the RX pin of the serial console in order to see what the board is transmitting. Speed (baud) 115200, Data bits 8, Stop bits 1, Parity none.
JTAG
→ port.jtag general information about the JTAG port, JTAG cable, etc.
J6 sure looks like a JTAG port, but it hasn't been tried.

Bootloader Mods
- you could read about bootloader in general
Some of the uBoot customizations made by the vendor can lead to confusion. Once you have access to the serial console, it's recommended to set bootdelay=3 (or whatever) and auto_recovery=off, after which whatever is in bootcmd will actually be run after the timeout.
The Marvell bootloader has some differences with respect to computing checksums of the u-boot environment flash partition, making modification of the environment via the standard OpenWrt tools a problem. It appears that the Sheeva U-Boot Tools should work, if you find it necessary to work with the environment from the OS (e.g., fw_printenv and fw_setenv.)

Notes
The EA4500 runs a bit warm hence it may not reboot when warm (hot). It's important for the EA4500 to stay cool with a fan blowing cool air straight at it during flashing and rebooting to avoid any complication. See discussion in Linksys Community See Forum
Placing it in the freezer for 2-3 mins also works.
On EA4500, OpenWrt wireless driver is mwl8k, which is unmaintained, has some functional limitations, and has been reported to have unstable wireless performance. Potential EA4500 users should consider if stable wireless connectivity is a priority before purchasing this device for OpenWrt usage.
The factory firmware EA4500 uses ap8x as wireless driver. The source code is contained in the GPL package. It is uses different kernel API and is only tested & targetted older kernel versions.
