ASUS AX4200 bootloop after upgraded from 23.05.4 to snapshot build

Very bad decision. And you didn't see the full scale of the problem.

This issue is not limited to one device.
There is already a device from Asus on the market that has the bootloader version 2022.10 installed (the specified patch is already included):

Proof: ASUS AX-1800S V2 (not RT-AX54) cant't flash with bootloader ver 2.0.0
I have already compiled OpenWrt 23.05.4 for RT-AX57M, but on the snapshot I will encounter the same problem.

And every day there will be more and more devices in which Uboot is installed with the specified fix (commit 36fee2f) and the presence of a common UBI partition.

At the moment, the issue is related to the following devices:

ASUS RT-AX52
ASUS RT-AX57M
ASUS RT-AX59U
ASUS TUF-AX4200
ASUS TUF-AX6000

The issue reported will likely affect the following devices:

ASUS RT-AX89X
OpenWrt One (of course there is a custom bootloader here)
mercusys,mr90x-v1
tplink,re6000xd
cellc,rtl30vw
teltonika,rutx10 
teltonika,rutx50 
zte,mf18a 
zte,mf282plus 
zte,mf286d 
zte,mf287 
zte,mf287plus 
zte,mf287pro 
zte,mf289f 
platform bcm4908 

There is a similar problem on the qcom platform (ipq80xx) and it is also solved by deceiving the logic of Uboot.
Example:

And here all hope is that the logic of the Uboot operation will remain the same (and there is a flaw in the logic).
Personally, I really don’t like such decisions (which are based on hope).
