Obtain SSH Access
1. Download and flash the firmware version 1.3.8 (China).
2. Login to the router web interface and get the value of `stok=` from the
   URL
3. Open a new tab and go to the following URL (replace <STOK> with the stok
   value gained above; line breaks are only for easier handling, please put
   together all four lines into a single URL without any spaces):
     http://192.168.31.1/cgi-bin/luci/;stok=<STOK>/api/misystem/set_config_iotdev
       ?bssid=any&user_id=any&ssid=-h%0Anvram%20set%20ssh_en%3D1%0Anvram%20commit
       %0Ased%20-i%20%27s%2Fchannel%3D.%2A%2Fchannel%3D%5C%5C%22debug%5C%5C%22%2F
       g%27%20%2Fetc%2Finit.d%2Fdropbear%0A%2Fetc%2Finit.d%2Fdropbear%20start%0A
4. Wait 30-60 seconds (this is the time required to generate keys for the
   SSH server on the router).

Create Full Backup
1. Obtain SSH Access.
2. Create backup of all flash (on router):
    dd if=/dev/mtd0 of=/tmp/ALL.backup
3. Copy backup to PC (on PC):
    scp root@192.168.31.1:/tmp/ALL.backup ./
Tip: backup of the original firmware, taken three times, increases the
chances of recovery :)

Calculate The Password
* Locally using shell (replace "12345/E0QM98765" with your router's serial
  number):
  On Linux
    printf "%s6d2df50a-250f-4a30-a5e6-d44fb0960aa0" "12345/E0QM98765" | \
    md5sum - | head -c8 && echo
  On macOS
    printf "%s6d2df50a-250f-4a30-a5e6-d44fb0960aa0" "12345/E0QM98765" | \
    md5 | head -c8
* Locally using python script (replace "12345/E0QM98765" with your
  router's serial number):
    wget https://raw.githubusercontent.com/eisaev/ax3600-files/master/scripts/calc_passwd.py
    python3.7 -c 'from calc_passwd import calc_passwd; print(calc_passwd("12345/E0QM98765"))'
* Online

Debricking (lite)
If you have a healthy bootloader, you can use recovery via TFTP using
programs like TinyPXE on Windows or dnsmasq on Linux. To switch the router
to TFTP recovery mode, hold down the reset button, connect the power
supply, and release the button after about 10 seconds. The router must be
connected directly to the PC via the LAN port.

Debricking
You will need a full dump of your flash, a CH341 programmer, and a clip
for in-circuit programming.

Install OpenWRT
1. Obtain SSH Access.
2. Create script (on router):
    echo '#!/bin/sh' > /tmp/flash_fw.sh
    echo >> /tmp/flash_fw.sh
    echo '. /bin/boardupgrade.sh' >> /tmp/flash_fw.sh
    echo >> /tmp/flash_fw.sh
    echo 'board_prepare_upgrade' >> /tmp/flash_fw.sh
    echo 'mtd erase rootfs_data' >> /tmp/flash_fw.sh
    echo 'mtd write /tmp/openwrt.bin firmware' >> /tmp/flash_fw.sh
    echo 'sleep 3' >> /tmp/flash_fw.sh
    echo 'reboot' >> /tmp/flash_fw.sh
    echo >> /tmp/flash_fw.sh
    chmod +x /tmp/flash_fw.sh
3. Copy `openwrt-ath79-generic-xiaomi_aiot-ac2350-squashfs-sysupgrade.bin`
   to the router (on PC):
    scp openwrt-ath79-generic-xiaomi_aiot-ac2350-squashfs-sysupgrade.bin \
    root@192.168.31.1:/tmp/openwrt.bin
4. Flash OpenWRT (on router):
    /bin/ash /tmp/flash_fw.sh &
5. SSH connection will be interrupted - this is normal.
6. Wait for the indicator to turn blue.

Welcome to Lean's git source of OpenWrt and packages

How to build your Openwrt firmware.

Note:

  1. DO NOT USE root USER FOR COMPILING!!!

  2. Users within China should prepare proxy before building.

  3. Web admin panel default IP is 192.168.1.1 and default password is "password".

Let's start!

  1. First, install Ubuntu 64bit (Ubuntu 20.04 LTS x86 is recommended).

  2. Run sudo apt-get update in the terminal, and then run sudo apt-get -y install build-essential asciidoc binutils bzip2 gawk gettext git libncurses5-dev libz-dev patch python3 python2.7 unzip zlib1g-dev lib32gcc1 libc6-dev-i386 subversion flex uglifyjs git-core gcc-multilib p7zip p7zip-full msmtp libssl-dev texinfo libglib2.0-dev xmlto qemu-utils upx libelf-dev autoconf automake libtool autopoint device-tree-compiler g++-multilib antlr3 gperf wget curl swig rsync

  3. Run git clone https://github.com/coolsnowwolf/lede to clone the source code, and then cd lede to enter the directory

  4. ./scripts/feeds update -a
./scripts/feeds install -a
make menuconfig

  5. Run make -j8 download V=s to download libraries and dependencies (user in China should use global proxy when possible)

  6. Run make -j1 V=s (integer following -j is the thread count, single-thread is recommended for the first build) to start building your firmware.

This source code is promised to be compiled successfully.

You can use this source code freely, but please link this GitHub repository when redistributing. Thank you for your cooperation!

Rebuild:

cd lede
git pull
./scripts/feeds update -a && ./scripts/feeds install -a
make defconfig
make -j8 download
make -j$(($(nproc) + 1)) V=s

If reconfiguration is need:

rm -rf ./tmp && rm -rf .config
make menuconfig
make -j$(($(nproc) + 1)) V=s

Build result will be produced to bin/targets directory.

Special tips:

  1. This source code doesn't contain any backdoors or close source applications that can monitor/capture your HTTPS traffic, SSL is the final castle of cyber security. Safety is what a firmware should achieve.

  2. If you have any technical problem, you may join the QQ discussion group: 297253733, link: click here

Router Recommendation

Not Sponsored: If you are finding a low power consumption, small and performance promising x86/x64 router, I personally recommend the EZPROv1 Alumium Edition (N3710 4000M): Details
