WETA Update notification only channel - Update notifications

This here is my personal setup and thought i'd share. Usually i test extensively before releasing to public, but if you do find something detrimental to the usage of your device that is either Force Closing or simply not working, let me know and i will in turn inform whether that is something i will tend to.

WETA is made for Music geeks like me, its main focus is stability and Audio. It is Based off latest firmware currently, and will always be using the most up to date firmware base.

This ROM is built from stock system images, decompiled and modded by me.

Flasing Instructions

Pretty simple really...

Get yourself onto stock Pie firmware, using Odin to flash the complete package. Before proceeding. Boot up and make sure you have OEM unlock switch and its activated.

Follow the instructions here to get TWRP and Root - https://forum.xda-developers.com/showthread.php?p=79483624

1. WETA Rom is now a Magisk Module. Download and flash in TWRP or Magisk Manager (must be done after Magisk has been installed and booted). You MUST have the same firmware base version as the module being flashed.
2. Boot up system, if it hangs on Samsung logo after 3min perform hard reboot.
3. Connect to internet and go to dev settings and cheeck oem unlock is present before any rebooting.

Maybe someone can give me some insight as to whether there is any cross platform possibility. I'll do a comparison on the firmware and see if they can be unified.

T835 works on t830 as well, i always flash kernel after system Installation to have this working. In t835 system images are dialer and mobile network options as you already noticed.

    Pie root and TWRP

    Below is a modified twrp img that will work with pie. I used @ashyx twrp to achieve this.

    Root is a custom kernel with security disabled and is permissive. Magisk is pre patched.

    1. Flash complete stock PIE using Odin.
    2. Boot up fully, connect to internet and open dev settings and check oem unlock is checked.
    3. Boot into download mode and flash WETA_Pie_T83x_Root+TWRP.tar in Odin. Don't let it boot to system, boot straight into TWRP.
    4. Flash T83x_PIE_encryptdisabler_+++.zip
    5. Format data in TWRP
    6. Reboot to recovery/TWRP
    7. Reboot to system

    If boot hangs on Samsung logo for more than 7min then force reboot. It should bootup then.

    There's always a chance of getting stuck with the unofficial binaries lockout message. If this happens flash stock Pie AP.tar with Odin. Boot and connect to internet then when you go to dev settings, oem unlock should be present and KG status should be back to checking. Remember this is all a work in progress
