EV3X Series Firmware for 4G LTE Routers
EV3X series firmware is using on EZR13/30/33/53 outdoor routers and EZR23 indoor router. They use the same architecture of Qualcomm Atheros QC9531 CPU with 128MB memory, and 16MB flash memory.
The EV3X firmware has built-in mobile module drivers and multiple networking protocols. The 4G router uses a built-in mini PCIe standard mobile module to communicate with cellular towers.
These 4G routers can bring you stable working performance and fast speed internet connections. Powered by open-source firmware, you have full root authority to access the web interface, SSH Telnet terminal, and file system.

Firmware Upgrade Tutorial
!IMPORTANT!
DO NOT turn off the power while flashing and resetting the firmware!
If run a critical upgrade with a leap of several versions, please reboot the router after flashed the new firmware.
It requires an Internet connection to download the firmware file online. Please make sure your 4G router is connected to the Internet.
- Log in router admin. Go to Click “System > Backup / Flash Firmware” on the top menu.
- Scroll down to the last section of “Online Upgrade“. Click the button of “Check New Version“.
- If a newer version is available, it will start to download it automatically, then jump to the verify page.
- Click “Proceed” to flash the new firmware. It will keep your current settings.
- Wait for 4~5 minutes until finish the flashing job.
Note: If the device lacks Hostname, Model number, or Serial Number, it will fail to download the firmware file. Please use the second option to upload firmware files manually on the web interface.
- Log in router admin. Click “Backup / Flash Firmware” under “System” on the top menu;
- Upload the firmware package by click “Browse…” on the section of “Flash new firmware image“, then click “Flash image…“.
- Click “Proceed” on the page of “Flash Firmware – Verify“.
- Wait for 3 minutes until the router flashed the new firmware and reboot. Log in router admin at gateway IP address 192.168.30.1. The default password is root or admin.
- Turn on the 4G router. Connect to Windows computer by LAN cable. Open browser and access router admin page.
- Open the software of WinSCP. Input parameter on the login page:
Protocol: SCP (default)
Hostname: 192.168.1.1 (router IP address)
Port: 22
Username: root (router admin user’s name)
Password: root (router admin password)
Click login, it will pop up a warning page on the first login. Click “Upgrade”. - Router files list in the right column. Access the patch of /tem.
Upload or drag the firmware file end with .bin to the patch of /tem - Open the software of PuTTY. Input connection parameter as below:
Hostname: 192.168.1.1 (router IP address)
Port: 22
Click “Open”.
It will pop up a warning page on the first login. Click “Yes”. - On the PuTTY terminal
Log in as: root (input router admin user’s name)
root@192.168.1.1’s password: root (input router admin password) - Input below command to start to flash the new firmware. Make sure to use the correct file name, for example, “firmware.bin”.
mtd -e firmware write /tmp/firmware.bin firmware - The return value is “Writing from /tmp/firmware.bin to firmware …”
Wait a few 3~5 minutes until return “root@openwrt:~#” - Now you can access the router admin with below data
Router IP address: 192.168.1.1 (router IP address)
User’s name: root
Password: root or admin
Require software: WinSCP & PuTTY
You can download them from their official website with free.
Suggest upgrade on Windows computer.
Suggest connecting to the outdoor router with LAN cable instead of Wi-Fi.
IMPORTANT
Ensure DO NOT disconnect the power supply during flashing the firmware!
Does the EV3120 firmware version work on an EZR30 Outdoor Modem? I am still running EV3108 on mine and am hoping to see Bridge Mode one day.
Newbie alert: I have just upgraded to EV3117-53 for my solar powered router. The upgrade is working fine but has changed the status overview and has now probvided a quite different display.
What I gained was a percentage signal strength which, whilst useful, has robbed me of the -x dBm values I have historically used to make comparisons. Plus I have no idea what reference the percentage is using to reverse engineer / guess the actual dBm. All other resources quote dBm values and this seems to me like dumbing it down a bit too much. Not unhappy just confused a little.
Also the global cell Id looks nothing like it used to and cannot be used on sites like Cellmapper.net to check which tower I am actually connected to which I used to be able to do. A way to get to the real 7 digit cell id would be useful. E.g. I usually connect to 5454593 and its now showing 868186040373266 for what I assume is the same cell.
Are there new ways via the CLI to get that info, as UQMI seems not to work now with the new protocol maanagament as the device is not /dev/cdc-wdm0 but is /sys/devices/platform/ehci-platform/usb1/1-1/1-1.3
UQMI fails to open that device. My ignorance no doubt but knowing how to interrogate the connection with that device would be useful, and for which I would be grateful.
Since the EV3117 firmware, the mobile protocol has switched to “MobileData”. We can use mmcli commands to configure the mobile modem. The “Signal Strength” changed to “Signal Quality” with a percentage for easier understanding. The signal get tutorial has been updated.
Thank you for the update
A OpenWRT 19.x based image would be nice! Is it safe to upgrade to vanilla OpenWRT 19?
Thank you for your advice. Please do not upgrade to OpenWRT v19.x. The 4G mobile modem can not work without pre-built drivers.
Are there any plans to release a 19.x firmware with the pre-built drivers?
We are working on v19.x. Will keep you posted.
Good instruction for the SSH firmware install.
One note there is a typo in the instruction. You want to scp the “UPDATE_NAME”.bin file to /tmp not /tm
The mtd command has the correct /tmp path.
