Ok so here is the guide for substratum.I tried susbtratum but there are no friendly guides on how to actually use substratum. What are you supposed to install? There are so many options. Android system, System UI, System notifications. I played around and installed some free themes but it just wasn't working out. I would get some settings but then when I click on a setting category settings are black/not visible.
P.S. I'm using stock ROM. I don't think that should matter right?
it's rather frustrating. Everyone just says use substratum, use substratum but I still don't know how to use it properly. It be great if anyone knew a friendly link or care to explain basics of substratum. I had to go back to TWRP because I got bootlooped using substratum.
You are using stock android and lenovo firmware don't support substratum. You must root your device and give substratum su permission to use it. And i thing you have already rooted the device so i recommend to using swiftblack theme for substratum. After download the theme open substratum and choose swift black and choose android version as other and then tick those apps you want to theme. Since you are on stock so many things don't work. Tick only those apps you have installed not system setting like android system, system ui etc.
I recommend applying 3-4 apps at a time and reboot your device And see what's working or not. If anything goes wrong just reboot in twrp and flash substratum rescue legacy zip. It will automatically uninstall any theme apply by substratum.
