ImageBuilder 19.07.4 for EnGenius ESR1750


I'm getting this error while trying to build an 19.07.4 image for EnGenius ESR1750:

Warning: /openwrt/openwrt-imagebuilder-19.07.4-ar71xx-generic.Linux-x86_64/build_dir/target-mips_24kc_musl/linux-ar71xx_generic/tmp/vmlinux-esr1750.uImage is too big (> 1441792 bytes)

I see that almost identical EnGenius EPG5000 uses ath79 target and runs the most recent 19.07.4 release.

Is it possible to reflash my device to EPG5000 or somehow port ESR1750 to ath79 and 19.07.4?

Thank you.

From 18.06.9 esr1750-squashfs-sysupgrade.bin
I flashed to 18.06.9 epg5000-squashfs-sysupgrade.bin
Then I flashed to 19.07.8 engenius_epg5000-squashfs-sysupgrade.bin


Nice, thanks for trying it out!
Have you noticed any issues after upgrade?

Issue? Just that I no longer have a ESR1750 but a EPG5000 instead.

The reported bitrate for the 5.0ghz wifi has gone up. It moves between 20mhz to 80mhz. I don't remember it was moving before at all with the older firmware.

I haven't have a chance to do file transfer to test actual speed.

Also, the upgrade process took 5-10 minutes. Just load the firmware and walk away for a bit.
