Re: [NAS542] Bricked device after custom firmware attempt - Stuck at "arch_number: 1094"
Flashing the official kernel and rootfs extracted from the latest firmware
.binfile.
Did you extract the kernel or the uImage? The loadaddress in your log is different from that of the stock kernel. See here.
Building a custom kernel (v4.19) with the correct
mvebu_v7_defconfigandLOADADDR
This is not a Marvel SoC!. It's a Mindspeed Comcerto 2000. It's not supported by the vanilla kernel, and AFAIK there is no usable kernel for it at all, other than the stock one.
Re: [2025 July Tips & Tricks] ⚙Set up your USG FLEX H before it’s online
How we did it before with the Flex 200's: We created an organization and site, connected an flex200 to it, and we configured it. Then, we cloned this organization to a new one (without disconnecting the flex 200). and called the organization "Customer Template", from then we always cloned this organization to a real organization, en connected een flex200 to it, then it took over the settings we created before in the first organization. i hope this is possible again.

Re: ATP800 V5.41(ABIQ.0) firmware image corrupted
The storage might be bad? Can you load firmware V5.40 on standby fine?
If it loads fine then some thing not right with your firmware you downloaded for this model
It also seem that Zyxel do the checksum on the .zip not .bin which I think is not a good idea but check the checksum matches here of the .zip

If the firmware is fine then its some config not being accepted
Re: WBE660s fail to update the firmware 7.10 to 7.20
I have ignored the update as I have to many old devices which not have WPA 3 - so far have no problem with continuing using firmware 7.2.
I have one WBE 660 and 6 NWA 130 in my network.
For example some older iPad Pro do not have WPA 3 and as well temperature measuring devices.
