I tried an mmkv utility ( https://github.com/topkan/mmkv-cli) but it doesn't seem to understand anything in the directory. it also seems to update the file very frequently; maybe every time you turn the device on. |
Thanks for your reference to mmkv-cli I was able to update the keys in the onyx_config store 'offline': I downloaded it to my laptop, did mmlv-cli get, edited key content in a text editor and then written it to the store using mmlv-cli set.
However as you correctly noted the store is being updated very frequently on the device itself and so it will get overwritten quickly after I replace it with my offline copy.
I suppose we need to boot the device into some mode where we can access the filesystem (via ADB?), but Onyx software that writes into onyx_config is not started.
Alternatively I'm thinking onyx_config can be made read-only, replaced with the offline updated copy and then device rebooted normally.
I have no idea how to do booting without Onyx software, but I could try the second route. However I'm worried that reboot may fail with this config file being read-only and I will end but with bricked device...
Hence seeking some advice here from more experienced people.
TIA
