SExperience advanced features

Samsung account features are not included in this ROM. If you want theming, you must use Substratum. Any features reliant on Knox are also not included and will not work.

Install

For G950F/FD ONLY

As with any ROM, by flashing you choose to enable these modifications on your device.
Your warranty will be gone and Knox will be tripped. I am not responsible for any damage caused
or problems encountered by your use of this firmware.

All builds I upload have been tested on my personal phone.

Any issues with TWRP should be asked in the TWRP thread.

Before proceeding, please create a backup of your /data/ partition using TWRP or by copying the files into some other external storage medium (USB, PC, cloud etc).

Make sure you are coming from an Oreo ROM and OEM unlock is enabled

Format Dalvik/ART cache, System, Data, Internal Storage, Cache in Wipe menu of TWRP

Flash ZIP through Install menu

When updating from a previous version of Altitude, simply download, reboot into TWRP, flash new ZIP and wipe Cache/Dalvik.
