will try to get them as soon as I free my serial adapter.

Check the host address

solved boot loop issue using this method. I used WInscp for offline install.

@frollic, any rationale for this behaviour? Previously, it was working fine via the GUI method. Not this time.

Good to know. I'll give a try on the 3700v4 when I can. Thanks for solving.

Updating to 23.05 is still an issue

Your device has had serious problems also earlier, so I wonder if the hardware (especially flash) is ok.

Your earlier survival story:

It might be that there is something wrong, e.g. a bad flash block at a place that strategically causes problems for a firmware/kernel of certain size. E.g. a bad block just where the UBI should start, or somethings similar.
Reference to your log:

Any solution to bad block? Custom built? e.g. removing some DNS stuff, bcz I don't use this as a router.

Where are you Guy's getting the upgrade from? https://downloads.openwrt.org/releases/ only goes as far as 22.03.05

Right. I'm only willing to test from 23.05.0-rc1 so I'll wait. Thanks

Hi.
A few days ago I compared the 3700v4 to the 4300v2 for the possibility of similar flash issue. I was wrong, the 3700v4 is similar to the 4300v1. Hardware is different in the 4300v2.
I was about to recover a 3700v4 when I checked the hardware specs of all these devices and noticed my error. So the 3700v4 can't help as comparison.

Looks like the definition/settings for the system console is initially right, but then gets changed wrongly...
