Telenor quirks
--------------
The operator specific firmware running on the Telenor branded
ZyXEL EX5700 includes U-Boot modifications affecting the OpenWrt
installation.
Notable changes to U-Boot include
- environment is stored in RAM and reset to defaults when power
cycled
- dual partition scheme with "nomimal" or "rescue" systems, falling
back to "rescue" unless the OS signals success in 3 attempts
- several runtime additions to the device-tree
Some of these modifications have side effects requiring workarounds
- U-Boot modifies /chosen/bootargs in an unsafe manner, and will crash
unless this node exists
- U-Boot verifies that the selected rootfs UBI volume exists, and
refuses to boot if it doesn't. The chosen "rootfs" volume must contain
a squashfs signature even for tftp or initramfs booting.
- U-Boot parses the "factoryparams" UBI volume, setting the "ethaddr"
variable to the label mac. But "factoryparams" does not always
exist. Instead there is a "RIP" volume containing all the factory
data. Copying the "RIP" volume to "factoryparams" will fix this
Hardware
--------
SOC: MediaTek MT7986
RAM: 1GB DDR4
FLASH: 512MB SPI-NAND (Mikron xxx)
WIFI: Mediatek MT7986 802.11ax 5 GHz
Mediatek MT7916 DBDC 802.11ax 2.4 + 6 GHz
ETH: MediaTek MT7531 Switch + SoC
3 x builtin 1G phy (lan1, lan2, lan3)
2 x MaxLinear GPY211C 2.5 N-Base-T phy (lan4, wan)
USB: 1 x USB 3.2 Enhanced SuperSpeed port
UART: 3V3 115200 8N1 (Pinout: GND KEY RX TX VCC)
Installation
------------
1. Download the OpenWrt initramfs image. Copy the image to a TFTP server
reachable at 192.168.1.2/24. Rename the image to C0A80101.img.
2. Connect the TFTP server to lan1, lan2 or lan3. Connect to the serial
console, Interrupt the autoboot process by pressing ESC when prompted.
3. Download and boot the OpenWrt initramfs image.
$ env set uboot_bootcount 0
$ env set firmware nominal
$ tftpboot
$ bootm
4. Wait for OpenWrt to boot. Transfer the sysupgrade image to the device
using scp and install using sysupgrade.
$ sysupgrade -n <path-to-sysupgrade.bin>
Missing features
----------------
- The "lan1", "lan2" and "lan3" port LEDs are driven by the switch but
OpenWrt does not correctly configure the output.
- The "lan4" and "wan" port LEDs are driven by the GPH211C phys and
not configured by OpenWrt.

Project ImmortalWrt
ImmortalWrt is a fork of OpenWrt, with more packages ported, more devices supported, better performance, and special optimizations for mainland China users.
Compared the official one, we allow to use hacks or non-upstreamable patches / modifications to achieve our purpose. Source from anywhere.
Default login address: http://192.168.1.1 or http://immortalwrt.lan, username: root, password: none.
Download
Built firmware images are available for many architectures and come with a package selection to be used as WiFi home router. To quickly find a factory image usable to migrate from a vendor stock firmware to ImmortalWrt, try the Firmware Selector.
If your device is supported, please follow the Info link to see install instructions or consult the support resources listed below.
Development
To build your own firmware you need a GNU/Linux, BSD or MacOSX system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.
Requirements
To build with this project, Ubuntu 20.04 LTS is preferred. And you need use the CPU based on AMD64 architecture, with at least 4GB RAM and 25 GB available disk space. Make sure the Internet is accessible.
The following tools are needed to compile ImmortalWrt, the package names vary between distributions.
- Here is an example for Ubuntu users:
-
Method 1:
Setup dependencies via APT
sudo apt update -y sudo apt full-upgrade -y sudo apt install -y ack antlr3 asciidoc autoconf automake autopoint binutils bison build-essential \ bzip2 ccache clang cmake cpio curl device-tree-compiler ecj fastjar flex gawk gettext gcc-multilib \ g++-multilib git gnutls-dev gperf haveged help2man intltool lib32gcc-s1 libc6-dev-i386 libelf-dev \ libglib2.0-dev libgmp3-dev libltdl-dev libmpc-dev libmpfr-dev libncurses5-dev libncursesw5 \ libncursesw5-dev libpython3-dev libreadline-dev libssl-dev libtool lld llvm lrzsz mkisofs msmtp \ nano ninja-build p7zip p7zip-full patch pkgconf python2.7 python3 python3-pip python3-ply \ python-docutils python3-pyelftools qemu-utils re2c rsync scons squashfs-tools subversion swig \ texinfo uglifyjs upx-ucl unzip vim wget xmlto xxd zlib1g-dev -
Method 2:
sudo bash -c 'bash <(curl -s https://build-scripts.immortalwrt.eu.org/init_build_environment.sh)'
-
Note:
- Do everything as an unprivileged user, not root, without sudo.
- Using CPUs based on other architectures should be fine to compile ImmortalWrt, but more hacks are needed - No warranty at all.
- You must not have spaces or non-ascii characters in PATH or in the work folders on the drive.
- If you're using Windows Subsystem for Linux (or WSL), removing Windows folders from PATH is required, please see Build system setup WSL documentation.
- Using macOS as the host build OS is not recommended. No warranty at all. You can get tips from Build system setup macOS documentation.
- For more details, please see Build system setup documentation.
Quickstart
- Run
git clone -b <branch> --single-branch --filter=blob:none https://github.com/immortalwrt/immortalwrtto clone the source code. - Run
cd immortalwrtto enter source directory. - Run
./scripts/feeds update -ato obtain all the latest package definitions defined in feeds.conf / feeds.conf.default - Run
./scripts/feeds install -ato install symlinks for all obtained packages into package/feeds/ - Run
make menuconfigto select your preferred configuration for the toolchain, target system & firmware packages. - Run
maketo build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.
