JCG Q30 Pro
JCG Q30 Pro is a router around 100RMB tailored for CMCC. The original firmware is a OEM fork from OpenWrt. As the original firmware was rumored having monitoring software from CMCC and the router itself can be “locked” by CMCC remotely, some people would eager to replace the original firmware with immoralWrt or “official” OpenWrt.
While original version of JCG Q30 Pro is equipped with 256MB ram, most sellers in pinduoduo and taobao are selling mod version of JCG Q30 Pro, which is having 512MB ram (Reported 486.98MiB available in OpenWrt status page).
Any text with a light background (like this one) provides instructions for creating the Details Page. When you have filled in correct/useful information (instead of any template that's there) remove the instructions, as well as the <WRAP> that encloses it.
Getting started with a new Device Page
- This is an empty template that suggests the information that should be present on a well-constructed Device Page. This means, that you have to fill it with life and information.
- There are several “fixme” tags with text on a light background (like this text) throughout this template. As you fill in the page, remove those tags so that people can judge its completeness.
- When there are no more “fixme” tags left, delete this one too, along with the
<WRAP>that encloses it.
Keep the articles modular
- Please include only model specific information, omit bla,bla and put everything generic into separate articles
- If you have no time to write certain stuff, link to docs
- base-system should lead the way, do not explain this again
- DO NOT provide a complete howto here! Instead groom the general documentation.

Hardware Highlights
Installation
→ Install OpenWrt (generic explanation)
You may either refer to the installation procedure mentioned in git or instructions below:
REF 1: https://mary.kevinmx.top/default/JCG-Q30-Pro.html
REF 2: https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=626344c9926dcf2db2e10681c19aab0328fee160
REF 1 is in Chinese. Use Google translate.
1. Software preparation
a. Putty b. tftpd64 c. (optional) nc
2. Backup OEM partition (optional)
Check REF 1 for backing up mtd 0-5 * According to REF 2, NMBM is disabled and therefore every Q30 pro shall have its own mtd 0-5 and not interchangeable.
3. Flash U-Boot
a. With reference to section 4.2 in REF 1 , Grab https://mirror-01.infra.openwrt.org/snapshots/targets/mediatek/filogic/openwrt-mediatek-filogic-jcg_q30-pro-bl31-uboot.fip and flash FIP in OEM U-Boot via Serial using tftp. b. type "reset" when done. c. wait for around 15 seconds until U-Boot console appears. Never touch the keyboard before U-Boot console appears, as U-Boot is writing partition changes in Rom. d. type reset when U-Boot console appears.
4. Flash BL2 preloader
By using Openwrt's U-Boot, Flash BL2 preloader and write NAND ( https://mirror-01.infra.openwrt.org/snapshots/targets/mediatek/filogic/openwrt-mediatek-filogic-jcg_q30-pro-preloader.bin) using tftp. reset when done.
5. Load recovery from tftp Server
The Openwrt's U-Boot shall automatically looking for openwrt-mediatek-filogic-jcg_q30-pro-initramfs-recovery.itb from tftp server (ip 192.168.1.254). Recovery file can be downloaded from https://firmware-selector.openwrt.org/?target=mediatek%2Ffilogic&id=jcg_q30-pro
6. In recovery, login to Web interface and perform firmware upgrade using SYSUPGRADE file downloaded from OpenWrt firmware selector
You may take reference from 360t7_1.0. Both routers are pretty much similar.
Flash Layout
Find out flash layout, then add the flash layout table here (copy, paste, modify the example).
Please check out the article Flash layout. It contains examples and explanations that describe how to document the flash layout.
OEM easy installation
Unlike immoralWRT, there is no easy installation at the moment. You need to open the case and attach serial for first flashing OpenWRT U-boot. See Installation Section
OEM installation using the TFTP method
Specific values needed for tftp
Enter values for “FILL-IN” below
| Bootloader tftp server IPv4 address | FILL-IN |
|---|---|
| Bootloader MAC address (special) | FILL-IN |
| Firmware tftp image | Latest OpenWrt release (NOTE: Name must contain “tftp”) |
| TFTP transfer window | FILL-IN seconds |
| TFTP window start | approximately FILL-IN seconds after power on |
| TFTP client required IP address | FILL-IN |
Upgrading OpenWrt
LuCI Web Upgrade Process
- Browse to
http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/LuCI Upgrade URL - Upload image file for sysupgrade to LuCI
- Wait for reboot
If OpenWrt version does not bump after upgrade, try using sysupgrade as descried below
Terminal Upgrade Process
If you don't have a GUI (LuCI) available, you can alternatively upgrade via the command line.
Note: It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing.
sysupgrade
- Login as root via SSH on 192.168.1.1, then enter the following commands:
cd /tmp wget https://downloads.openwrt.org/snapshots/targets/mediatek/filogic/openwrt-mediatek-filogic-jcg_q30-pro-squashfs-sysupgrade.itb sysupgrade /tmp/openwrt-mediatek-filogic-jcg_q30-pro-squashfs-sysupgrade.itb
