This database may not have up-to-date information and may even recommend a build which might cause issues. As such, you should check the device specific forum (Broadcom, Atheros, MediaTek, etc.) first before flashing any build recommended in this database. There you will find build specific topics that discuss any issues with a particular build/release. For more up-to-date firmware files, please visit the firmware faq.
It is a general rule of thumb that most devices that require activation aren't always given support here in the forum, hence the reason why no build release threads exist in this area.

I'm not able to find any information about flashing Unifi devices on this forum. Is there any chance ...?
I have already read this forum thread and the article (and many others ...). But I think it's differentent devices (AirOS products, Unifi with U-boot, Atheros based, ...)
TFTP is not working with DD-WRT images. I have tried many combinations but all leads to "Firmware check failed! (-2)" message.
I could try differentent build version using SSH CLI flash tool...
Is there any way of support given the fact that these devices are under paid licence?
this was on a UAP-AC-PRO(broadcom; FCC ID:SWX-UAPAC; console claimed it was v2)....
I know this is not the originals posters exact ap, but I want to post this somewhere as it might help as I believe they use the same firmware
1) https://ftp.dd-wrt.com/dd-wrtv2/downloads/betas/2022/08-10-2022-r49677/ubnt_UAP-AC-LR/ << started with this firmware, as instructions state copied over "flash-upgrade.bin" to /tmp
2) a slight change from the instructions I used "mtd -f flash-upgrade.bin linux && mtd -f write /tmp/flash-upgrade.bin linux2"
** this after waiting, reseting and trying to factory reset resulted in it booting to recovery(page on 192.168.1.20 showing "Broadcom miniWeb Server" via a browser
3) loaded dd-wrt-44715-unifiac-preflash.bin(latest from ddwrt database for UAP AC); after a bit of loading/etc it than booted to ddwrt:D!
** I realize it might be possible to go direct but in case, this did work for me
than had to pay for activation

I contacted DD-WRT support team and they were really kind.
The correct way to install DD-WRT firmware is using TFTP. However it seems broken with latest Unifi FW.
I was advised to use mtd command from device to flash it.
Copy (for example with "scp") FW to /tmp folder of device. Then run:
Code:
mtd -f write /tmp/dd-wrt-43471-unifiac-preflash.bin linux
mtd -f write /tmp/dd-wrt-43471-unifiac-preflash.bin linux2
