[Samsung Galaxy Note 20 Ultra ROMs, Kernels, Recove] exocetdj:
Install procedure for V2.4 onwards has changed drastically as has the format of the module base itself

From now on N20U and soon on N10 and Tab, there will be no more 4gb zip files to flash (im sick of the time wasted waiting for copying and flashing lol) - the total size of files has gone from 4.5GB to 450mb but you will have exactly the same end result!!!!!!

I have created an "Mother Module" or "MM" which, when flashed in Magisk, places a (Magisk installed) Rom Module zip and a (TWRP flashable) Module Base Convertor zip into their own folder on internal/420.

The next thing to do is to go to TWRP and locate the Module Base Convertor zip and flash it. This will apply all debloat and This will also trigger a marker that will allow the rom module to be flashed.

Once the first zip is flashed, you can then go and install the rom module as normal in Magisk

I will be providing rooted stock firmware to start the whole thing off :)

BEFORE YOU START. DO NOT ATTEMPT TO FLASH THIS OVER A DIFFERENT DEVS ROM - IT WILL CAUSE ISSUES. BACKUP APPS AND DO A FRESH STOCK INSTALL FIRST - that's even if you get past the failsafe ;)

Install process assuming you are on matching firmware to the released Rom and rooted

1, Flash the mother module in Magisk - reboot to TWRP

2, In TWRP, flash Module Base Convertor located in internal/420- this will apply all the modifications and debloat to your rom that i used to on the Old full size zips

3, reboot and install rom module in Magisk as normal- all done!!!

Install Process assuming you are coming from earlier 420rom:

1, Using the odin files i have provided, flash BL, Modded AP, CP and HOMECSC in Odin with AUTOREBOOT off

2, Keeping phone plugged in, hold vol down and power to exit download and immediately hold vol up and power to enter TWRP.

3, flash Multidisabler & reboot.

4, Flash the mother module in Magisk - reboot to TWRP

5, In TWRP, flash Module Base Convertor - this will install a few generic niceties seen on the module bases of old (No red text etc) and debloat a fair whack of crap out

6, reboot and install rom module in Magisk as normal- all done!!!

on a side note........................

How i patch and add TWRP to the Stock AP file - aka making stock rooted odin flashable files

Producing a stock rooted firmware is really easy and i would hope it would be part of people's standard updating process from now on & will take most people 10 mins if instructions on Xda are read through :) but I will make them nonetheless.

1, extract firmware zip so you have BL, AP, CP and HOMECSC visible (Put CSC aside)

2, copy AP to internal on phone and patch with Magisk (install -> select and patch file). Once done, copy the Modded AP file (also called magisk patched tar) that Magisk produced from /downloads on your phone's internal storage back to your firmware folder - call this one Modded AP or whatever.

3, get the latest TWRP and rename to recovery.img, drop the image into the magisk_patched.tar (delete recovery.img.lz4 if present)

4, extract the BL folder and delete vbmeta.img.lz4 in the extracted folder, pull out vbmeta.img from magisk_patched.tar and copy to the BL extracted folder - re-tar this BL folder using 7z. DO NOT REMOVE VBMETA.img from magisk_patched tar - call this one modded BL file or whatever.

5, you can now go ahead and flash Modded BL, Modded AP, CP and Homecsc in odin
