Subject: [PATCH] ramips: add factory image for TP-Link EC330-G5u v1
This commit adds factory.bin image for TP-Link EC330-G5u v1. This allows
to install OpenWrt without connecting a serial cable (UART).
Installation using factory image
--------------------------------
Tested with "3.16.0 0.9.1 v6037.0 Build 191016 Rel.30619nb" TP-Link
firmware.
1. Login to the router web interface (http://192.168.0.1/ by default) and
save running config to "conf.bin" file
2. Open configuration file in any TP-Link config editor (e.g.
https://jahed.github.io/tp-link-config-editor/)
3. Find "DeviceInfo" section and insert a new string "<Description
val="Modem Router`telnetd -p 1023 -l login`" />" according to the
following example:
<DeviceInfo>
...
<Description val="Modem Router`telnetd -p 1023 -l login`" />
...
</DeviceInfo>
4. Save configuration file and upload changed configuration using stock
firmware interface
5. Login using telnet to IP:192.168.0.1 (Username:admin, password:1234)
6. Run "cat /proc/mtd | grep mtd7"
a. If the result is 'mtd7: 03000000 00020000 "rootfs" 03400000',
then install stock firmware using web interface to toggle booted
firmware image from "os1" to "os0"
b. If the result is 'mtd7: 03000000 00020000 "rootfs" 00400000',
then all is ok, go to the next step
7. Set up a tftp server with OpenWrt factory.bin image (IP:192.168.0.100
in this example)
8. Login using telnet to 192.168.0.1
9. Download OpenWrt factory.bin image from the tftp server:
cd /tmp
tftp -g -r factory.bin 192.168.0.100
10. Write OpenWrt factory.bin image:
dd if=/tmp/factory.bin of=/dev/mtdblock1
11. Power cycle the router
