KuWFi C910 is an 802.11n (300N) indoor router with LTE support.

I can't find anywhere the OEM firmware. So if you want to restore the
original firmware you must do a dump before the OpenWrt flash.

According to the U-Boot, the board name is Iyunlink MINI_V2.

Hardware
--------
SoC:   Qualcomm QCA9533 650/400/200/25/25 MHz (CPU/RAM/AHB/SPI/REF)
RAM:   128 MB DDR2 16-bit CL3-4-4-10 (Nanya NT5TU64M16HG-AC)
FLASH: 16 MB Winbond W25Q128
ETH:
  - 2x 100M LAN (QCA9533 internal AR8229 switch, eth0)
  - 1x 100M WAN (QCA9533 internal PHY, eth1)
WIFI:
  - 2.4GHz: 1x QCA9533 2T2R (b/g/n)
  - 2 external non detachable antennas (near the power barrel side)
LTE:
  - Quectel EC200T-EU (or -CN or -AU depending on markets)
  - 2 external non detachable antennas (near the sim slot side)
BTN:
  - 1x Reset button
LEDS:
  - 5x White leds (Power, Wifi, Wan, Lan1, Lan2)
  - 1x RGB led (Internet)
UART: 115200-8-N-1 (Starting from lan ports in order: GND, RX, TX, VCC)

Everything works correctly.

MAC Addresses
-------------
LAN XX:XX:XX:XX:XX:48 (art@0x1002)
WAN XX:XX:XX:XX:XX:49 (art@0x1002 + 1)
WIFI XX:XX:XX:XX:XX:48

LABEL XX:XX:XX:XX:XX:48

Installation
------------
Turn the router on while pressing the reset button for 4 seconds.
You can simply count the flashes of the first lan led. (See notes)
If done correctly you should see the first lan led glowing slowly and
you should be able to enter the U-Boot web interface.

Click on the second tab ("固件") and select the -factory.bin firmware
then click "Update firmware".

A screen "Update in progress" should appear.

After few minutes the flash should be completed.

This procedure can be used also to recover the router in case of soft
brick.

Backup the original firmware
----------------------------
The following steps are intended for a linux pc. However using the
right software this guide should also work for Windows and MacOS.

1) Install a tftp server on your pc. For example tftpd-hpa.

2) Create two empty files in your tftp folder called:
	kuwfi_c910_all_nor.bin
	kuwfi_c910_firmware_only.bin

3) Give global write permissions to these files:
	chmod 666 kuwfi_c910_all_nor.bin
	chmod 666 kuwfi_c910_firmware_only.bin

4) Start a netcat session on your pc with this command:
	nc -u -p 6666 192.168.1.1 6666

5) Set the static address on your pc: 192.168.1.2. Connect the router
	to your pc.

6) Turn the router on while pressing the reset button for 8-9 seconds.
	You can simply count the flashes of the first lan led. If you
	press the reset button for too many seconds it will continue
	the normal boot, so you have to restart the router. (See notes)

7) If done correctly you should see the U-Boot network console and you
	should see the following lines on the netcat session:
Version and build date:
  U-Boot 1.1.4-55f1bca8-dirty, 2020-05-07

Modification by:
  Piotr Dymacz <piotr@dymacz.pl>
  https://github.com/pepe2k/u-boot_mod

u-boot>

8) Start the transfer of the whole NOR:
	tftpput 0x9f000000 0x1000000 kuwfi_c910_all_nor.bin

9) The router should start the transfer and it should end with a
	message like this (pay attention to the bytes transferred):
TFTP transfer complete!

Bytes transferred: 16777216 (0x1000000)

10) Repeat the same transfer for the firmware:
	tftpput 0x9f050000 0xfa0000 kuwfi_c910_firmware_only.bin

11) The router should start the transfer and it should end with a
	message like this (pay attention to the bytes transferred):
TFTP transfer complete!

Bytes transferred: 16384000 (0xfa0000)

12) Now you have the backup for the whole nor and for the firmware
	partition. If you want to restore the OEM firmware from OpenWrt
	you have to flash the kuwfi_c910_firmware_only.bin from the
	U-Boot web interface.

	WARNING: Don't use the kuwfi_c910_all_nor.bin file. This file
	is only useful if you manage to	hard brick the router or you
	damage the art partition (ask on the forum)

Notes
-----
This router (or at least my unit) has the pepe2k's U-Boot. It's a
modded U-Boot version with a lot of cool features. You can read more
here: https://github.com/pepe2k/u-boot_mod

With this version of U-Boot, pushing the reset button while turning on
the router starts different tools:
 - 3-5 seconds: U-Boot web interface that can be used to replace the
 	firmware, the art or the U-Boot itself
 - 5-7 seconds: U-Boot uart console
 - 7-10 seconds: U-Boot network console
 - 11+ seconds: Normal boot

The LTE modem can be used in cdc_ether (ECM) or RNDIS mode.
The default mode is ECM and in this commit only the ECM software is
included. In order to set RNDIS mode you must use this AT command:
	AT+QCFG="usbnet",3
In order to use again the ECM mode you must use this AT command:
	AT+QCFG="usbnet",1

Look for "Quectel_EC200T_Linux_USB_Driver_User_Guide_V1.0.pdf" for
other AT commands

1. Use ARTIFACTS to build factory image. This change allows users to
   generate initramfs factory image using OpenWrt ImageBuilder.

2. Override the default bootargs property defined in "mt7621.dtsi".
   Although we use the "bootargs-override" property to set bootargs,
   the default "bootargs" property will still be written into the
   device tree, so it is better to override it.

Make use of KERNEL_MAKE in kernel packages were easily possible.
This moves some more code to common places and reduces the number of
lines.

It is defined like this:
KERNEL_MAKE = $(MAKE) $(KERNEL_MAKEOPTS)
KERNEL_MAKEOPTS = -C $(LINUX_DIR) $(KERNEL_MAKE_FLAGS)
Signed-off-by: NHauke Mehrtens <hauke@hauke-m.de>

KERNEL_MAKEOPTS will get expanded when it is used and not when it is
defined in the kernel.mk file now. This fixes problems finding dependent
kernel modules when it is used by a kernel module package.

Without this change the build of packages which depend on other out of
tree modules failed when they used KERNEL_MAKE because some symbols could
not be found. This happened because KERNEL_MAKE_FLAGS which contains a
"if $(__package_mk)" was  evaluated where KERNEL_MAKEOPTS was defined
and not when the KERNEL_MAKE was used. For packages which included
kernel.mk before package.mk we saw this problem. One workaround
was to use the correct include order and the other one was to not
use KERNEL_MAKE_FLAGS, but copy its content.

In this implementation, the flash partition layout is adjusted to avoid
modifying the uboot environment of mtdparts. This ensures that the 30M
ubi_kernel partition remains aligned with the stock ubi partition, and
the kernel volume is placed in it. This allows the stock uboot to boot
from it without changing the mtdparts, which is useful for reverting back
to the stock firmware using Xiaomi Firmware Tools. In actual testing,
modifying mtdparts has been found to break Xiaomi Firmware Tools.

1. use ARTIFACTS to generate initramfs-factory.ubi for easy installation.
2. The NAND flash layout is changed to allow for reverting back to the
   stock firmware.
3. Before performing sysupgrade, do some cleanup in platform_pre_upgrade
   to ensure a clean installation of OpenWRT.
4. Setup the uboot env to ensure that the system always boot, which can
   be helpful for users who may forget to do this before sysupgrade in
   the initramfs.

New flash instructions:
1. Gain ssh access. Please refer to:
   https://openwrt.org/toh/xiaomi/redmi_ax6000#installation)

2. Check which system current u-boot is loading from:
   COMMAND: `cat /proc/cmdline`
   sample OUTPUT: `console=ttyS0,115200n1 loglevel=8 firmware=1 uart_en=1`
   if firmware=1, current system is ubi1
   if firmware=0, current system is ubi0

3. Setup nvram and write the firmware:
   If the current system is ubi1, please set it up so that the next time
   it will boot from ubi, and write the firmware to ubi:
```
nvram set boot_wait=on
nvram set uart_en=1
nvram set flag_boot_rootfs=0
nvram set flag_last_success=0
nvram set flag_boot_success=1
nvram set flag_try_sys1_failed=0
nvram set flag_try_sys2_failed=0
nvram commit
ubiformat /dev/mtd8 -y -f /tmp/initramfs-factory.ubi
```
   If the current system is ubi, please set it up so that the next time
   it will boot from ubi1, and write the firmware to ubi1:
```
nvram set boot_wait=on
nvram set uart_en=1
nvram set flag_boot_rootfs=1
nvram set flag_last_success=1
nvram set flag_boot_success=1
nvram set flag_try_sys1_failed=0
nvram set flag_try_sys2_failed=0
nvram commit
ubiformat /dev/mtd9 -y -f /tmp/initramfs-factory.ubi
```

4. After rebooting, the system should now boot into the openwrt initramfs.
   Flash the squashfs-sysupgrade.bin via using ssh or luci.
```
sysupgrade -n /tmp/squashfs-sysupgrade.bin
```
Done.

For existing users of the Redmi AX6000 running OpenWrt, here are the steps to
switch to this new layout:

1. Flash initramfs-factory.ubi
```
mtd -r -e ubi write /tmp/initramfs-factory.ubi ubi
```

2. After rebooting, the system will boot into the new openwrt-initramfs.
Log in and perform a sysupgrade to complete the process.
```
