This thread is still open so I'll ask it here --
I'm trying to do an initial flash of OpenWRT to a GS110TPP, starting from Netgear firmware 7.0.9.19 via the Netgear web interface, without success so far.
Output from show startup-config in the Netgear CLI (just to verify the hardware & firmware versions):
myname# show startup-config
SYSTEM CONFIG FILE ::= BEGIN
! Model: GS110TPP
! System Description: GS110TPP 8-Port Gigabit PoE+ Ethernet Smart Managed Pro Switch with 2 Copper Ports and Cloud Management
! Firmware Version: 7.0.9.19 [Oct 30 2023 - 20:31:44]
! Loader Version: 1.0.0.5 [2019-03-15 17:08:23 UTC]
! Config Version: 1
! Hardware Version: 0
The GS110TPP is listed as "supported" in the OpenWRT hardware directory (and in the firmware search / config utility) but there is no specific install / config help page for it, so I tried just following the instructions for the GS308Tv1 instead, directly uploading the latest GS110TPP firmware
openwrt-23.05.2-realtek-rtl838x-netgear_gs110tpp-v1-initramfs-kernel.bin
through the Netgear web interface (Maintenance --> Update --> HTTP Firmware/File Update. It simply won't accept the OpenWRT firmware.
Fails with the following:
I've also tried copying
openwrt-23.05.2-realtek-rtl838x-netgear_gs110tpp-v1-initramfs-kernel.bin
via TFTP from the Netear "CLI Lite" management interface which is accessible at telnet port 60000 on the router, but that also fails:
(* I renamed the full openwrt-23.05...kernel.bin file on the tftp server to 'initramfs.bin' for sake of simplicity/brevity at the command line.)
myname# copy tftp://192.168.1.30/initramfs.bin flash://image1
Downloading file. Please wait...

I tried the same tftp copy command to get the GS108T_110TP_TPP_V7.0.9.19.bix firmware instead, just to see whether the CLI tftp was perhaps filtering by file or extension name, but it gave the same result, "FAILED."
(I checked carefully to be sure that my TFTP server was working fine using other test hosts, etc. This isn't a network configuration issue as far as I can see.)
Any hints? Do I need to set up UART / serial access to proceed from here?
