Hi Group,

I have been reading this thread and the Lineage thread. My end goal is to have a device running Lineage 18.1, rooted with Magisk and with TWRP recovery installed.

Can I accomplish this by starting with TWRP and installing Lineage and Magisk or do I have to have Lineage install according to the instructions in the lineage thread first then install TWRP afterwards?

Does anyone have a link to the most current guide or walk though of the steps to accomplish this, starting from a newly purchased G986B/DS phone?

Thank you.

    https%3A%2F%2Fwww.maketecheasier.com%2Fassets%2Fuploads%2F2019%2F01%2Ftwrp-featured.jpg

    Exynos ONLY.
    In NO way it is compatible with Snapdragon variants including but not limited to American(U/A/T/P/V), Chinese(0/8/6), Hong Kong(0), Japanese(SC-*), Canadian(W) variants.


    Special Notes:
    1. DON'T FORGET TO ENABLE "OEM UNLOCK" (located in Developers options).
    2. KNOX will be tripped once you flashed custom binaries to your phone.
    (Your warranty may be voided. However this may not affect you if your country forces Samsung to provide hardware warranty regardless of software status.)
    3. Samsung Firmware OTA (aka System Updates) will no longer work once you flashed custom binaries.
    (You can flash custom ROMs if you want to keep the OS up-to-date.)
    4. All apps that use KNOX like Samsung pay, Secure Folder and maybe more will no more work

    2. power off the device and boot in download mode with vol up+ vol down buttons and plug in the usb (make sure usb cable is connected to the pc)
    3. in download mode you see the long press vol up option for unlock bl
    4. unlock the bootloader (that will wipe your device so be sure you made a backup of your data)
    5. after bootloader unlock boot up the phone and make sure it is connected to the internet or he triggers rmm prenormal

    so update for One UI 3.0 is uploaded. like all time patched vbmeta is not needed for boot twrp. if you mods somethings in system or vendor then its needed that you flash a patched vbmeta
