Hi All,
I have a LBR20 that appers to have custom firmware (not Voxel, wish it was) that has the device completely locked down. Admin password is set, reset button disabled, password recovery disabled.
I have serial access and have tried to tftp the stock firmware, the transfer failes about 75% through the transfer (prefetch abort).
Any ideas on how to gain access/re-flash?
Thanks.

Hey hazarjast. Any chance you can email me too? Maybe a PM? I am in through com part (putty) and need the same kind of help. Persistent flash keeps on restoring custom data. Was able to change basic variables (said and wifi password) but cannot change the root pass. If you can help please kindly get back to me. I am at (loomax2023) on gm@i1. Thanks.

Maybe it is too late and you handle , but in LBR20 it is no problem to use s"standard Neatgear recovery tool" https://github.com/jclehner/nmrpflashxyznyc76 wrote: Sun Aug 20, 2023 6:34 pm Hey hazarjast.

If you have not already used the official TFTP recovery from Netgear that would be my recommendation https://kb.netgear.com/000059633/How-do ... ft-Windows
Otherwise it looks like @MiG41 has made a recommendation of third party tool as well. Apologies, I no longer have an LBR20 and have moved to other projects so would be unable to provide any direct assistance.
