Hi, I recently bought Asus RT-AX53U as replacement for Archer C6 ( mainly because flash size ) but after installing 23.05.03 build of openwrt overlay partition is only ~33MB.
AFAIK this router supports dual firmware, but I don't need it and I would appreciate all the available NAND storage ( should be around 100MB ), can I do something about it w/o forking and building firmware myself?
Are there any steps which should be done to "maximize" the size of the /overlay partition?
(I do not need any backward compatibility with original Asus fw)
Asus bootloader recovery is a bit picky about modified own ubi parts. I mean not restore flash to sales content but to casually reset back without extra gadgets...
Asus rescue does it anyways. I suppose it's ment to rescue it even if there are some new bad blocks.
Still the answer to the original question is, it's possible to take full advantage of the flash. Just like there already has been done by RT-AX54 version.
