Hello, my RT-AC88U have been working fine, but i rebooted it for something i forgot and it wont turn on and just been rebooting. i have tried to reflash it before( it was using marlin before) but with asus rescue tool it would always fail at 32mb. So i reflash it with dd-wrt since it was smaller at 27mb. and it was all read the size is right and all but it keeps boot looping. is it a hardware problem?

Welcome to our lively community.

Which dd-wrt file did you use and which version of dd-wrt was it?
You should try this http://ftp.dd-wrt.com/dd-wrtv2/downloads/betas/2022/09-15-2022-r50176/asus-rt-ac88u/asus_rt-ac88u-firmware.trx.

previous to flashing press your reset button for 10 seconds and use the asus recovery tool to reflash file above.

Hello i have reflash it with your given firmware, but the same problem occured...

is it possible the router doesnt support dd-wrt? i have read a couple of post that suggest not all ac88u support dd-wrt. i was running merlin before and well it kinda bricked itself after a reboot.

also is it possible a bad nand be the culprit? i know it was able to read from the flash chip from the logs but just curios.

thanks

Can't you use the WPS reset method to clear the nvram? Via serial, you should be able to do an nvram erase as well.

i think erasing the nvram made it worse

No idea really nothing jumps out from those logs, you may want to try to put the router in recovery mode and use the asus recovery tool to flash back to stock from early 2019 (important to use old stock builds that aren't locked to 3rd party) and then from there flash to current DD-WRT build 50274.

We hope that all you have connected is the TX, RX, and GND leads. This looks rather interesting. Normally, a serial nvram erase is followed by a reboot command or flash command.

ok I have fixed it, thanks everyone

turns out it has a serious problem with the 3.3v rails, after installing/replacing one of the 3.3v rails with a buck converter and setting it to a bit of a higher voltage (3.38v) it was stable enough to boot. I checked it before and it was fine, I guess with load the voltage dropped and crashes the router, and finally killed the rail.
