It's assumed in this community that users understand the basics of root and custom recoveries, and how to recover their devices if they run into problems. We're not responsible for anything you do to your device.

🔹 Stock devices other than Nexus are not officially supported,, don't report issues if you choose to use Substratum on an unsupported device. More info

🔹 Substratum does NOT work on ROMs with the CM theme engine

🔹 Legacy does not include boot animations or fonts and requires a reboot

SUBSTRATUM LEGACY ON STOCK NEXUS AOSP 6.0 or 7.0. Legacy does not include boot animations or fonts and requires a reboot.

🔹1. Install TWRP, make a backup.
🔹2. Root
🔹3. Uninstall some Google apps from the system partition to make room on the system partition (Can be reinstalled from play store)
🔹4. Do not apply the Android system overlay after the November security patch or you will have bootloops, heed the bootloop warnings in Substratum


🔹 Flash the rescue zips located inside the Substratum folder on internal storage.
🔹 Substratum OMS - reboot into TWRP and remove the xml from /data/system/overlay.xml
🔹 Legacy - Mount system in TWRP and remove the overlays from system/vendor/overlays
🔹 Legacy devices with vendor partitions (Nexus 9, 5x, 6p, Pixel C, Marlin, Sailfish) mount vendor then remove overlays from vendor/overlay manually.
