I don't have my f8132 with me right now, so I'll refine this in a few hours when I can check it rather than reciting from memory, but here's a solution to the OEM partition problem.
Note that this is potentially dangerous if you don't know what...
United Arab Emirates.
Incidentally, that's very similar to what I paid for my G8142 in Hong Kong in late August.
Edit: I'm currently holding off until this works with Oreo, but kudos to sToRm// nonetheless!
does it work on Dual model?
I haven't tried NeilDK's build specifically, but I've built and run AOSP 8.0 from the same source on my F8132 (Xperia X Performance Dual).
For those using this on dual SIM devices, you'll need to keep qcrilmsgtunnel around if you want to make/receive calls or adjust dual SIM settings. May be worth removing it from the script's removal list for this reason.
