Hui! With Trust. Says vendor patches out of date
Addonsu does not work.

Addonsu does not work.

Last security patch from Xiaomi was 2017-1-1, that's why vendor patch is out of date (and will always be).

You have to enable root manually in Developer settings after installing the addonsu package.

But kernel can be patched?
Need logs?

 

[nicknitewolf]

Need logs?

Sorry the addonsu package on LineageOS's Download page is broken. Try this build for now instead.
