has anyone had issue's with flashing 09-10-2022-r50146? i recently fully bricked my ASUS RT-AC5300 of which it was unrecoverable and just now same with my Archer C9. with the RT-AC5300, 2022/09-03-2022-r50057 was very fast and worked besides locking up completely 10 minutes after full boot. both devices after never came back up with 09-10-2022-r50146 right after webgui flash. both devices running flawlessly with older versions of dd-wrt. my Archer C9 won't even recover from a successful ftfp upload. it just sits in boot loop. i've literally purchased bootlooped Archer C9's and restored them using tftp. this is the first time i've not been able to recover the device.

every time i flash i clear all settings to defaults.

really disconcerning as now i'm left with my Asus AC1900P with a stable r48607 std (04/08/22). i am defeated to even think about updating this firmware as its my last router outside of a bunch of Linksys WRT54G's and one remaining Archer C9 left in storage.

Possible causes can be choosing reset after upgrade and/or upgrading while using jffs2

You may think I'm obsessive, but please also check your power supply, since it has previously been reported that bootloop was in fact due to a lack of power, ie voltage dropping way below nominal voltage at startup, because under certain conditions, device was asking more amperage than rated.

So, if you can, please live check input voltage while running, it would be great.

@hachiroku

For the C9, if the tftp fails, only serial recovery will return the unit to live, for more info, I can share my experience with you:

Good luck!
