Currently it's not possible to flash factory images on devices shipped
with vendor firmware versions 1.1.0 Build 20201120 rel. 50406 (published
2020-12-22):
(curFw_ver, newFw_ver) == (1.1, 1.0) [NM_Error](nm_checkSoftVer) 00848: Firmwave not supports, check failed.
[NM_Error](nm_checkUpdateContent) 01084: software version dismatched
[NM_Error](nm_buildUpgradeStruct) 01188: checkUpdateContent failed.
They've even following note in release notes:
Note: You will be unable to downgrade to the previous firmware version
after updating this firmware.
This version check in vendor firmware is implemented in
/usr/bin/nvrammanager binary likely as following C code[1]:
sscanf(buf, "%d.%d.%*s",&upd_fw_major, &upd_fw_minor);
...
if (((int)upd_fw_major < (int)cur_fw_major) ||
((ret = 1, cur_fw_major == upd_fw_major && (upd_fw_minor < (int)cur_fw_minor)))) {
ret = 0;
printf("[NM_Error](%s) %05d: Firmwave not supports, check failed.\r\n\r\n","nm_checkSoftVer" ,0x350);
}
...
return ret;
So in order to fix this and make it future proof it should be enough to
ship our factory firmware images with major version 7 (lucky number).
Tested on latest firmware version 1.1.2 Build 20210125 rel.37999:

The TP-Link EAP235-Wall is a wall-mounted, PoE-powered AC1200 access
point with four gigabit ethernet ports.
When connecting to the device's serial port, it is strongly advised to
use an isolated UART adapter. This prevents linking different power
domains created by the PoE power supply, which may damage your devices.
The device's U-Boot supports saving modified environments with
`saveenv`. However, there is no u-boot-env partition, and saving
modifications will cause the partition table to be overwritten. This is
not an issue for running OpenWrt, but will prevent the vendor FW from
functioning properly.
Device specifications:
* SoC: MT7621DAT
* RAM: 128MiB
* Flash: 16MiB SPI-NOR
* Wireless 2.4GHz (MT7603EN): b/g/n, 2x2
* Wireless 5GHz (MT7613BEN): a/n/ac, 2x2
* Ethernet: 4× GbE
* Back side: ETH0, PoE PD port
* Bottom side: ETH1, ETH2, ETH3
* Single white device LED
* LED button, reset button (available for failsafe)
* PoE pass-through on port ETH3 (enabled with GPIO)
Datasheet of the flash chip specifies a maximum frequency of 33MHz, but
that didn't work. 20MHz gives no errors with reading (flash dump) or
writing (sysupgrade).
Device mac addresses:
Stock firmware uses the same MAC address for ethernet (on device label)
and 2.4GHz wireless. The 5GHz wireless address is incremented by one.
This address is stored in the 'info' ('default-mac') partition at an
offset of 8 bytes.
From OEM ifconfig:
eth a4:2b:b0:...:88
ra0 a4:2b:b0:...:88
rai0 a4:2b:b0:...:89
Flashing instructions:
* Enable SSH in the web interface, and SSH into the target device
* run `cliclientd stopcs`, this should return "success"
* upload the factory image via the web interface
Debricking:
U-boot can be interrupted during boot, serial console is 57600 baud, 8n1
This allows installing a sysupgrade image, or fixing the device in
another way.
* Access serial header from the side of the board, close to ETH3,
pin-out is (1:TX, 2:RX, 3:GND, 4:3.3V), with pin 1 closest to ETH3.
* Interrupt bootloader by holding '4' during boot, which drops the
bootloader into its shell
* Change default 'serverip' and 'ipaddr' variables (optional)
* Download initramfs with `tftpboot`, and boot image with `bootm`
# tftpboot 84000000 openwrt-initramfs.bin
# bootm
Revert to stock:
Using the tplink-safeloader utility from the firmware-utils package,
TP-Link's firmware image can be converted to an OpenWrt-compatible
sysupgrade image:
$ ./staging_dir/host/bin/tplink-safeloader -B EAP235-WALL-V1 \
-z EAP235-WALLv1_XXX_up_signed.bin -o eap235-sysupgrade.bin
This can then be flashed using the OpenWrt sysupgrade interface. The
image will appear to be incompatible and must be force flashed, without
keeping the current configuration.
Known issues:
- DFS support is incomplete (known issue with MT7613)
- MT7613 radio may stop responding when idling, reboot required.
This was an issue with the ddc75ff704 version of mt76, but appears to
have improved/disappeared with bc3963764d.

Because some padding values in the TP-Link safeloader image generation
were hardcoded, different values were sometimes used throughout a
factory image. TP-Link's upgrade images use the same value everywhere,
so let's do the same here.
Although a lot of TP-Link's safeloader images have padded partition
payloads, images for the EAP-series of AC devices don't. This padding is
therefore also made optional.
By replacing the type of the padding value byte with a wider datatype,
new values outside of the previously valid range become available. Use
these new values to denote that padding should not be performed.
Because char might be signed, also replace the char literals by a
numeric literal. Otherwise '\xff' might be sign extended to 0xffff.
This results in factory images differing by 1 byte for:
* C2600
* ARCHER-C5-V2
* ARCHERC9
* TLWA850REV2
* TLWA855REV1
* TL-WPA8630P-V2-EU
* TL-WPA8630P-V2-INT
* TL-WPA8630P-V2.1-EU
* TLWR1043NDV4

* RE355
* RE450
* RE450-V2
* RE450-V3
* RE500-V1
* RE650-V1
The following factory images no longer have padding, shrinking the
factory images by a few bytes for:
* EAP225-OUTDOOR-V1
* EAP225-V3
* EAP225-WALL-V2
* EAP245-V1
* EAP245-V3

TP-Link safeloader firmware images contain a number of (small)
partitions with information about the device. These consist of:
* The data length as a 32-bit integer
* A 32-bit zero padding
* The partition data, with its length set in the first field
The OpenWrt factory image partitions that follow this structure are
soft-version, support-list, and extra-para. Refactor the code to put all
common logic into one allocation call, and let the rest of the data be
filled in by the original functions.
Due to the extra-para changes, this patch results in factory images that
change by 2 bytes (not counting the checksum) for three devices:
* ARCHER-A7-V5
* ARCHER-C7-V4
* ARCHER-C7-V5
These were the devices where the extra-para blob didn't match the common
format. The hardcoded data also didn't correspond to TP-Link's (recent)
upgrade images, which actually matches the meta-partition format.
A padding byte is also added to the extra-para partition for EAP245-V3.

- 128MiB RAM
- 3 GBit Ports (QCA8337)
- PLC (QCA7550)
Installation
------------
Installation is possible from the OEM web interface. Make sure to
install the latest OEM firmware first, so that the PLC firmware is
at the latest version. However, please also check the Wiki page
for hints according to altered partitioning between OEM firmware
revisions.
Notes
-----
The OEM firmware has 0x620000 to 0x680000 unassigned, so we leave
this empty as well. It is complicated enough already ...

TP-Link EAP245 v3 is an AC1750 (802.11ac Wave-2) ceiling mount access
point. UART access (for debricking) requires non-trivial soldering.
Specifications:
* SoC: QCA9563 (CPU/DDR/AHB @ 775/650/258 MHz)
* RAM: 128MiB
* Flash: 16MiB SPI-NOR
* Wireless 2.4GHz (SoC): b/g/n 3x3
* Wireless 5GHz (QCA9982): a/n/ac 3x3 with MU-MIMO
* Ethernet (QCA8337N switch): 2× 1GbE, ETH1 (802.3at PoE) and ETH2
* Green and amber status LEDs
* Reset switch (GPIO, available for failsafe)
Flashing instructions:
All recent firmware versions (latest is 2.20.0), can disable firmware
signature verification and use a padded firmware file to flash OpenWrt:
* ssh into target device and run `cliclientd stopcs`
* upload factory image via web interface
The stopcs-method is supported from firmware version 2.3.0. Earlier
versions need to be upgraded to a newer stock version before flashing
OpenWrt.
Factory images for these devices are RSA signed by TP-Link. While the
signature verification can be disabled, the factory image still needs to
have a (fake) 1024 bit signature added to pass file checks.
Debricking instructions:
You can recover using u-boot via the serial port:
* Serial port is available from J3 (1:TX, 2:RX, 3:GND, 4:3.3V)
* Bridge R237 to connect RX, located next to J3
* Bridge R225 to connect TX, located inside can on back-side of board
* Serial port is 115200 baud, 8n1, interrupt u-boot by holding ctrl+B
* Upload initramfs with tftp and upgrade via OpenWrt
Device mac addresses:
Stock firmware has the same mac address for 2.4GHz wireless and
ethernet, 5GHz is incremented by one. The base mac address is stored in
the 'default-mac' partition (offset 0x90000) at an offset of 8 bytes.
ART blobs contain no mac addresses.

TP-Link has introduced a compatibility level to prevent certain
downgrades. This information is stored in the soft-version partition,
changing the data length from 0xc to 0x10.
The compatibility level doesn't change frequently. For example, it has
the following values for the EAP245v3 (released 2018-Q4):
* FW v2.2.0 (2019-05-30): compat_level=0
* FW v2.3.0 (2019-07-31): compat_level=0
* FW v2.3.1 (2019-10-29): compat_level=1
* FW v2.20.0 (2020-04-23): compat_level=1
Empty flash values (0xffffffff) are interpreted as compat_level=0.
If a firmware upgrade file has a soft-version block without
compatibility level (data length < 0x10), this is also interpreted as
compat_level=0.
By including a high enough compatibility level in factory images, stock
firmware can be convinced to accept the image. A compatibility level
aware firmware will keep the original value.
Example upgrade log of TP-Link EAP245v3 FWv2.3.0 to FWv2.20.0:
[NM_Debug](nm_fwup_verifyFwupFile) 02073: curSoftVer:2.3.0 Build

upDataStart = 7690604b, upDataLen = 00000018
[NM_Debug](updateDataToNvram) 00738: PTN 07: write bytes = 000002eb
Other firmware upgrades have been observed to modify the compabitility
stored level (e.g. TP-Link EAP225-Outdoor FWv1.4.1 to FWv1.7.0).
Therefore, it seems to be the safest option to set the OpenWrt
compatibility level to the highest known value instead of the highest
possible value (0xfffffffe), to ensure users do not get unexpectedly
refused firmware upgrades when using a device reverted back to stock.
To remain compatible with existing devices and not produce different
images, the image builder doesn't store a compatibility level if it is
zero.
