Enable external antenna

[lgk321q]

Hello,

I'm trying to enable the external antenna on the Vocore2 ultimate using the instructions on https://vocore.io/v2u.html. I'm running into the same issue mentioned in this post (viewtopic.php?f=16&t=3889).

Currently using the firmware 20191127.bin. Are there any steps to allow writing to factory or does the firmware need to be built with a config option to allow writing?

To enable second antenna, need to modify factory setting one byte.
Default openwrt locked that partition as read-only, so it can not modify unless you use a customed firmware.
Or use a special driver to unlock it, reference to http://vonger.cn/?p=15037 (this blog is talking about unlock u-boot, change it to factory it will unlock factory partition)
