Installation
-------------
1. Log in to LuCI
2. Go to System, Backup / Flash Firmware
3. If desired, backup the current system by saving (all) the mtdblock
contents.
4. Flash new firmware image, select Flash image.
5. Browse and select the sysupgrade file
"openwrt-*-ramips-mt7621-edup_ep-rt2983-squashfs-sysupgrade.bin"
and then Upload.
6. Unselect "Keep settings and retain the current configuration"
Note: All settings will be reset to default. WiFi is not enabled by
default so a connection via Ethernet is necessary to log in and set up.
7. Allow "Force upgrade" (tick the box if there is one), or press Continue
if there is no box to tick. This is because the name is now
"edup,ep-rt2983" as it should have been from the start.
8. Proceed to flash. Wait for reboot and keep power connected.
9. After reboot, default address to access LuCI is 192.168.1.1 with
no password

Recovery (UART)
----------------
1. Remove the 4 screws on the bottom and pry open the cover.
2. Connect serial adapter to the unpopulated serial header pins
TX, RX, GND near the WPS button. Do not connect VCC.
3. Start serial terminal (e.g. minicom, screen, etc) on the computer and
turn on the router.
4. As prompted, hit any key to stop autoboot.
5. Enter 2 to select "2. Upgrade firmware"
6. Enter 0 to select "0 - TFTP client (Default)"
7. Accept the defaults by pressing Enter for
"Input U-Boot's IP address: 192.168.1.1",
"TFTP server's IP address: 192.168.1.2",
"Input IP netmask: 255.255.255.0"
8. Assign your PC's Ethernet port a static IP 192.168.1.2 with netmask
255.255.255.0 and connect to a LAN port on the router using the
Ethernet cable. Disconnect all other network connections (e.g. WiFi) on
the computer.
9. Serve the factory image
"openwrt-*-ramips-mt7621-edup_ep-rt2983-squashfs-factory.bin" using
a TFTP server, e.g. tftpd64. For convenience, the filename can be renamed
to something shorter.
10. In the serial terminal, when prompted "Input file name:", enter the
filename from the previous step and press Enter.
11. The factory image will be flashed as indicated. Wait for reboot.
