RT-BE88U can't install merlin

[Jackson]

Hello. I have a brand new RT-BE88U (arrived today). Tried install merlin image RT-BE88U_3006_102.2_0_nand_squashfs.pkgtb.
Comes up saying "firmware upgrade unsuccessful. This may result from incorrect image or error transmission. Please check the version of firmware and try again".

I have tried:
* re-downloading the merlin image
* re-installing official firmware manually (latest version available as below, successful)
* factory reset, logging in to 192.168.50.1 through browser, answering the initial questions then straight to firmware upgrade.

Any ideas please?

RT-BE88U	Current Version : 3.0.0.6.102_37094-g9192b87_980-gbd310_BB0B

The 37094 you have was released only a day or so ago.
Maybe it sees the (slightly) older Merlin firmware as something it won’t/can’t go back to?

So I recently turned my old AX58u into an AImesh node, since I bought the BT10 to be my main router.

As I tried to get the Ax58u onto the latest Asus-released router from usual merlin-for-main router - I had encountered the same problem. The root of the problem, found from an old thread here, was that Asus had changed the firmware size/codebase after Oct 2021 - which required me to load up the Oct 2021 FW from Asus first on the Ax58u, and only then I could switch to the latest Asus release for the Ax58u. Otherwise, I got the same message you were getting. The older Oct 2021 fw binary had a size of ~56 MB, while the latest one had size of ~106 MB - indicative of Asus' change.

negative, the size is just because this model has a v2 which uses a different cpu,

the actual cause of your issue issue was that code signing changed between the release of the product and the latest versions of the firmware, the older firmware has no idea how to interpret the hashing schemes of the current firmwares so you need to first flash a firmware that is still signed in the former hash scheme but knows how to read the newer scheme.

Understand the hashing difference, thanks.

However, given I have v1 of the AX58u - why/how did the release of the v2 (with different CPU) cause the change/double the binary size of the same v1 hardware, after Oct 2021 ?

it includes unique platform code specific to each model, it will only deploy the code specific to either one on the corresponding model.

I have the exact same issue, on the exact same router. I read a few other ways to install custom firmware on asus routers, but I'm not sure what to do to be honest.

RT-AC66U_B1: Unable to flash - Invalid Firmware Upload/Firmware upgrade unsuccessful

I purchased a new RT-AC66U B1 (AC1750 ARM w/ USB3) but every Fresh Tomato firmware I attempt to install fails. All attempts to flash have been done through the Administration panel > Firmware Upgrade. I see either: "Invalid Firmware Upload" right away or it pretends to flash with a progress...
