Flashing a UAP with openwrt still possible?

[BillyBlaze]

Hi,

I have read some of the other threads regarding this but info is a little thin.

Are the details found on this link https://openwrt.org/toh/ubiquiti/unifi still correct today starting from here;
"rootfs partition is removed so firmware upgrade fail. By serial port break the U-BOOT boot for the prompt"
my unifi AP is running version 4.x so if I have serial access I can proceed with installing openwrt 19.x?

Thanks.

Did you read/visit the forum thread noted on the page you linked?

[BillyBlaze]

Yes. It mentions ubiquiti blocking 3rd part installations but also serial access may be possible.

@BillyBlaze

It mentions ubiquiti blocking 3rd part installations but also serial access may be possible.

So, I take that as a no.

I'll assist:

Are Ubiquiti actively blocking installation of Third Party Firmware?

i've recently came up with an idea how to flash locked/signed firmware on litebeam ac gen2. basically you start flashing same ubiquiti fw that is already on device and interrupt the process, that leaves mtd partitions unlocked and you can flash another image to these using dd. more info in this GH comment-> https://github.com/openwrt/openwrt/pull/689#issuecomment-493658317 let us know if it works on unifi and other ubiquiti hw

Hope this helps.

Do you have an AC model or one of the older models with n wifi?

If running 4.x on an n model, first obtain a 3.x firmware from Ubiquiti and downgrade it.

There is an ath79 build for the old model now which should be used instead of ar71xx.
