Spectrum SAX1V1K is a AX WIFI router with 3 1G and 1 2.5G ports.
The router is provided to Spectrum customers.
It is OEM of Askey RT5010W
https://forum.openwrt.org/t/spectrum-sax1v1k-askey-rt5010w-openwrt-support/149923
It continues the original work by @MeisterLone to get this device supported.
Specifications:
```
• CPU: Qualcomm IPQ8072A Quad core Cortex-A53 2.2GHz
• RAM: 2048MB of DDR3
• Storage: 1024MB eMMC
• Ethernet: 3x 1G RJ45 ports (QCA8075) + 1 2.5G Port (QCA8081)
• WLAN:
• 2.4GHz: Qualcomm QCN5024 4x4 802.11b/g/n/ax 1174 Mbps PHY rate
• 5GHz: Qualcomm QCN5054 4x4 802.11a/b/g/n/ac/ax 2402 PHY rate
• LED: 1 gpio-controlled dual color led (blue/red)
• Buttons: 1x reset
• Power: 12V DC jack
```
Notes:
```
• This commit adds only single partition support, that means
sysupgrade is upgrading the current rootfs partition.
• Installation can be done by serial connection only.
• A poulated serial header is onboard
https://forum.openwrt.org/t/spectrum-sax1v1k-askey-rt5010w-openwrt-support/149923/6
• RX/TX is working, u-boot bootwait is active, secure boot is enabled.
```
Installation Instructions:
**Most part of the installation is performed from an initramfs image.**
Boot initramfs : Using serial connection
1. Boot up the device and wait till it displays "VERIFY_IB: Success. verify IB ok"
2. Once that message appears,
login with username 'root'
password serial number of your router in uppercase.
3. Use vi to paste the 'open.sh' script from @MeisterLone github on your device
https://github.com/MeisterLone/Askey-RT5010W-D187-REV6/blob/master/Patch/open.sh
4. chmod 755 open.sh
5. ./open.sh
6. Set your ip to 192.168.0.1
7. Run a TFTP server and host the initramfs image on the TFTP server and name it "recovery.img"
8. Reboot device. On boot it will try TFTP.
Install OpenWrt from initramfs image:
1. Use SCP (or other way) to transfer OpenWrt factory image
2. Connect to device using SSH (on a LAN port)
3. Flash firmware: sysupgrade
# sysupgrade -n -v /tmp/openwrt_sysupgrade.bin
4. Set U-boot env variable: bootcmd
# fw_setenv bootcmd "run fix_uboot; run setup_and_boot"
5. Reboot the device
# reboot
6. Once device is booted, residue of previous firmware will prevent openwrt to work properly.
Factory Reset is MUST required
# Once serial console is displaying to login, hold reset button for 10 sec
7. Now everything should be operational.
Note: this PR adds only single partition support, that means sysupgrade is
upgrading the current rootfs partition

With the change in version schema the downloaded files changed, too,
mostly the hash is now prefixed with a tilde `~` instead of a dash `-`.
Since each downloaded archive contains folder with the same name as the
archive, the checksum changed.

Different from OPKG, APK uses a deterministic version schema which chips
the version into chunks and compares them individually. This enforces a
certain schema which was previously entirely flexible.
- Releases are added at the very and end prefixed with an `r` like
`1.2.3-r3`.
- Hashes are prefixed with a `~` like `1.2.3~abc123`.
- Dates become semantic versions, like `2024.04.01`
- Extra tags are possible like `_git`, `_alpha` and more.

Netgear WAX214 is a 802.11 ax dual-band AP
with PoE. (similar to Engenius EWS357APV3)
Specifications:
• CPU: Qualcomm IPQ6010 Quad core Cortex-A53
• RAM: 512MB of DDR3
• Storage: 128MB NAND (Macronix MX30UF1G18AC)
• Ethernet: 1x 1G RJ45 port (QCA8072) PoE
• WIFI:
2.4GHz: Qualcomm QCN5022 2x2 802.11b/g/n/ax 574 Mbps PHY rate
5GHz: Qualcomm QCN5052 2x2 802.11a/b/g/n/ac/ax 1201 PHY rate
• LEDs:
4 x GPIO-controlled LEDs
- 1 Power LED (orange)
- 1 LAN LED (blue)
- 1 WIFI 5g LED (blue)
- 1 WIFI 2g LED (blue)
black_small_square Buttons: 1x soft reset
black_small_square Power: 12V DC jack or PoE (802.3af )
An populated serial header is onboard, format is
1.25mm 4p (DF13A-4P-1.25H)
RX/TX is working, bootwait is active, secure boot is not
enabled.
The root password of the stock firmware is unknown,
but failsafe mode can be entered to reset the password.
Installation Instructions:
- obtain serial access
- stop auto boot (press "4", Entr boot command line
interface)
- setenv active_fw 0 (to boot from the primary rootfs,
or set to 1 to boot from the secondary rootfs
partition)
- saveenv
- tftpboot the initramfs image
- bootm
- copy
openwrt-qualcommax-ipq60xx-netgear_wax214-squashfs-factory.ubi
to the device
- write the image to the NAND:
- cat /proc/mtd and look for rootfs partition (should
be mtd11,
or mtd12 if you choose active_fw 1)
- ubiformat /dev/mtd11 -f -y
openwrt-qualcommax-ipq60xx-netgear_wax214-squashfs-factory.ubi
- reboot
Note: the firmware is senao-based. But I was unable to build
a valid senao-header into the image.
Maybe they changed the header format and senaoFW isn't
working any more.

OpenWRT Installation
1. Simplest way is just do upgrade from webpage with *factory.img
2. You can also do it with standard tool for Netgear's debricking - NMPRFlash
3. Most advanced way is to open device , connect to UART console and :
- Prepare OpenWrt initramfs image in TFTP server root (server IP 192.168.1.10)
- Connect serial console (115200,8n1) to UART connector
- Connect TFTP server to RJ-45 port
- Stop in u-Boot and run u-Boot command:
> setenv serverip 192.168.1.10
> set fdt_high 0x85000000
> tftpboot 0x83000000 openwrt-ipq40xx-generic-netgear_lbr20-initramfs-zImage.itb
> bootm 0x83000000
- Login via ssh
- upload or download *sysupgrade.bin ( like wget ... or scp transfer)
- Install image via "sysupgrade -n" (like “sysupgrade -n /tmp/openwrt-ipq40xx-generic-netgear_lbr20-squashfs-sysupgrade.bin”)
Back to Stock
- Download firmware from official Netgear's webpage , it will be *.img file after decompressing.
- Use NMRPFlash tool ( detailed insructions on project page https://github.com/jclehner/nmrpflash )
Open the case
- Unscrew nuts and remove washers from antenna's conectors.
- There are two Torx T10 screws under the label next to antenna conectors. You have to unglue this label from left and right corner to get it
- Two parts of shell covers will slide out from eachother , you have to unglue two small rubber pads and namplate sticker on bottom to do that.
- PCB is screwed with 4Pcs of Torx T10 screws
- Before lifting up PCB remove pigtiles for LTE antennas and release them from PCB and radiator (black and white wires)
- On other side of PCB ,in left bottom corner there is already soldered with 4 pins UART connector for console. Counting from left it is +3,3V , TX , RX ,GND (reffer to this picture: https://i.ibb.co/Pmrf9KB/20240116-103524.jpg )

Open Linksys Web UI - http://192.168.1.1/ca or http://10.65.1.1/ca depending on your setup.
Login with your admin password. The default password can be found on a sticker under the device.
To enter into the support mode, click on the “CA” link and the bottom of the page.
Open the “Connectivity” menu and upload the squash-factory image with the “Choose file” button.
Click start. Ignore all the prompts and warnings by click “yes” in all the popups.
The Wifi radios are turned off by default. To configure the router, you will need to connect your computer to the LAN port of the device.
Then you would need to write openwrt to the other partition for it to work
- First Check booted partition
