Asus ax59u installation question

Installing and Using OpenWrt
1

Hello,

I want to install OpenWrt on an asus rt-ax59u router. I was following the guide here: https://openwrt.org/toh/asus/rt-ax59u and for the easy installation method it says to download a trx with a warning:
"(trx image is unofficial image, you may need to be used with caution.)"

My question is, what is it talking about? can I trust the trx? could it be a problem for my network security? There is a bin file on the official repository but I saw no reference on the guide to this file (only rgd the sysupgrade).

Did anyone install the trx file for this router?

Thank you for your time

it means file isn't coming from "here" (openwrt.org), but from a 3rd party.
since you're only using it as the easy way of flashing vanilla openwrt, it shouldn't be an issue.

if you still don't want to use it, you can flash the device using serial - https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=782eb050082acac93c2f9b3eb22348234bc93e99

Thank you for your quick response!

I don't fully understand the first part of your answer, does it mean that the trx (potential) "issues" are overwritten when I flash the sysupgrade?

I'm just worried because it is weird that the official documentation insists on verifying the .bin files' checksum but then you need to flash a trx coming from a drive, with no hash to verify it with.

yes.

the verify checksum obviously applies to official openwrt images, the gdrive file isn't one of those.
the only person who would be able to provide a checksum would be the owner/creator.

this firmware lives inside your router for as long as it takes you to flash the 2nd image, see it as a bridgehead to proper openwrt.

Checksum (crc32) of the TRX image is checked during installation (both in the system and in the bootloader)
