This device is a 'Range extender' variant of the Xiaomi 4A router.
Its identical to the 100m non-intl/chinese version as much as it can run
the same firmware, differences being form factor, LEDs, WPS button
and one 100M port only.
The stock firmware differs significantly, being 'app managed only'.

2. Attach UART, switch on the router and interrupt the boot process by
pressing 't'
3. Load and run OpenWrt initramfs image:
tftpboot
bootm
4. Once inside OpenWrt, switch to the first boot image:
fw_setenv BootImage 0
5. Run 'sysupgrade -n' with the sysupgrade OpenWrt image
Back to Stock
-------------
1. Run in the OpenWrt shell:
fw_setenv BootImage 1
reboot
Recovery
--------
1. Press Reset button and power on the router
2. Navigate to U-Boot recovery web server (http://192.168.0.1/) and upload

Notes
-----
[1] WAN MAC address:
a. First octet of WAN MAC is differ than others and OUI is not related
to TP-Link company. This probably should be fixed.
b. Flipping bits in first octet and hex delta are different for the
different MAC examples:
+-----------------+----------------+----------------+
| | Example 1 | Example 2 |
+-----------------+----------------+----------------+
| LAN | 68 = 0110 1000 | 50 = 0101 0000 |
| MAC (1st octet) | ^ ^ ^ | |
+-----------------+----------------+----------------+
| WAN | 72 = 0111 0010 | 54 = 0101 0100 |
| MAC (1st octet) | ^ ^ ^ | ^ |
+-----------------+----------------+----------------+
| HEX delta | 0xa | 0x4 |
+-----------------+----------------+----------------+
| DEC delta | 4 | 4 |
+-----------------+----------------+----------------+
c. DEC delta is a constant (4). This looks like a mistake in OEM
firmware and probably should be fixed.
Based on the above, I decided to keep correct OUI and make WAN MAC =
label + 1.
[2] Bootloaders
The device contains 3 bootloaders:
- First U-Boot: U-Boot 1.1.3 (Mar 18 2019 - 12:50:24). The First U-Boot
located on NAND Flash to load next full-feature Uboot.
- Main U-Boot + its backup: U-Boot 1.1.3 (Mar 18 2019 - 12:50:29). This
bootloader includes recovery webserver. Requires special uImages to
continue the boot process:
0x00 (os0, os1) - firmware uImage
0x40 (os0, os1) - standalone uImage (OpenWrt kernel is here)
- Additionally, both slots of the original TP-Link firmware contains
Image U-Boot: U-Boot 1.1.3 (Oct 16 2019 - 08:14:45). It checks image
magics and CRCs. We don't use this U-Boot with OpenWrt.

This is an RTL8393-based switch with 48 RJ-45 and 2 SFP ports.
Hardware
--------
SoC: Realtek RTL8393M
RAM: 128MB DDR3 (Nanya NT5CC64M16GP-DI)
FLASH: 8MB NOR (Macronix MX25L6433F)
ETH: 48x 10/100/1000 Mbps RJ-45 Ethernet
SFP: 2x SFP
BTN:
- 1x Reset button
LEDS:
- 50x Green-Amber leds: lan/sfp status
- 1x Green led: power (Always on)
UART:
- 115200-8-N-1 (CN3, pin-out on PCB)
Everything works correctly except for the 2 SFP ports that are not
working unless you enable it every boot in U-Boot with the command:
rtk network on
Installation
------------
You can install Openwrt using one of the following methods.
Warning: flashing OpenWrt will delete your current configuration.
Warning 2: if the -factory.bix file is not available anymore, you must
follow Method 2.
Method 1:
Check the firmware version currently running on your switch. If you are
running FW V1.0.1.10 or greater, you have to download the firmware
V1.0.1.8 from Netgear website and then flash this version. When the
switch restarts, it should be on version V1.0.1.8. Now you can get the
OpenWrt -factory.bix file and then flash it using the OEM web interface.
Method 2 (requires the UART connection):
Boot the -initramfs-kernel.bin image from U-Boot with these commands:
rtk network on;
tftpboot 0x8f000000 openwrt-realtek-rtl839x-netgear_gs750e-initramfs-kernel.bin;
bootm;
And then flash the -sysupgrade.bin file from OpenWrt.
Revert to stock
---------------
Get the stock firmware from the Netgear website and flash it using the
OpenWrt web interface. Remember to not keep the current configuration
and check the "Force upgrade" checkbox
Once reverted to stock the firmware could complain in the UART console
about mtdblock3 and/or mtdblock4 not being mounted correctly but it
seems to work anyway without any problems. Sample error:
mount: Mounting /dev/mtdblock4 on /mntlog failed: Input/output error
If you want to get rid of these error messages you can boot the
-initramfs-kernel.bin image from U-Boot with these commands:
rtk network on;
tftpboot 0x8f000000 openwrt-realtek-rtl839x-netgear_gs750e-initramfs-kernel.bin;
bootm;
And then erase the corresponding partitions using the command:
For mtdblock3:
mtd erase jffs2_cfg
For mtdblock4:
mtd erase jffs2_log
Now you can reboot the switch and the errors should be gone
Note
----
To get the SFP ports fully working, all the right GPIOs must be found.
In the GPL sources I found these:
- GPIO_14: SFP_TX_DIS1;
- GPIO_19: SFP_TX_DIS0;

Upstream commit [1] included in the Linux kernel version 6.2 was
backported to Linux kernels 6.1.4, 6.0.18. It should be possible that it
is going to be backported even to the 5.15 series, but before it happens,
let's include it here.
It was discovered that on SOC Marvell Armada 3720, which is using e.g.
Turris MOX, and if you are also using it with older ARM Trusted Firmware
v1.5, it is not possible to detect connected USB 3.0 devices, but they
are working just fine when connected with USB 2.0 cable. This patch
fixes it.

Thats happening likely due to the fact, that on buildbots we've

The pins of the MT7530 switch that translate to GPIO 0, 3, 6, 9 and 12 has
got a function, by default, which does the same thing as the netdev
trigger. Because of bridge offloading on DSA, the netdev trigger won't see
the frames between the switch ports whilst the default function will.
Do not use the GPIO function on switch pins on devices that fall under this
category.
Keep it for:
mt7621_belkin_rt1800.dts: There's only one LED which is for the wan
interface and there's no bridge offloading between the "wan" interface and

to boot openwrt without touching the flash.
TFTP is not reliable due to bugged bootloader,
set MTU to 600 and try many times.
If your TFTP server supports setting block size,
higher block size is better.
Splitting the file into 1 MB parts may be necessary
example:
$ tftpboot 0x80100000 image1.bin
$ tftpboot 0x80200000 image2.bin
$ tftpboot 0x80300000 image3.bin
$ tftpboot 0x80400000 image4.bin
$ tftpboot 0x80500000 image5.bin
$ tftpboot 0x80600000 image6.bin
$ bootm 0x80100000
**Return to OEM:**
The best way to return to OEM firmware
is to have a copy of the MTD partitions
before flashing Openwrt.
Backup copies should be made of partitions
"fwconcat0", "loader", and "fwconcat1"
which together is the same flash range
as OEM's "rootfs" and "uimage"
by loading an initramfs.bin
and using LuCI to download the mtdblocks.
It is also possible to extract from the
OEM firmware upgrade image by splitting it up
in parts of lengths that correspond
to the partitions in openwrt
and write them to flash,
after gzip decompression.
After writing to the firmware partitions,
erase the "reserved" partition and reboot.
**OEM firmware image format:**
Images from Fortinet for this device
ending with the suffix .out
are actually a .gz file
The gzip metadata stores the original filename
before compression, which is a special string
used to verify the image during OEM upgrade.
After gzip decompression, the resulting file
is an exact copy of the MTD partitions
"rootfs" and "uimage" combined in the same order and size
that they appear in /proc/mtd and as they are on flash.
OEM upgrade is performed by a customized busybox
with the command "upgrade".
Another binary, "restore"
is a wrapper for busybox's "tftp" and "upgrade".
