Hello ..... !!!!! Thank you very much for your efforts on this ROM! Personally, you and your friends who worked together to make this ROM, this is a great and beautiful work ....... and thank you again, thank you! The only question of this One UI 3.1 that you put is the new Android 11? And in the meantime, if Gravity and Exposed work in it, please post the exact installation method .... Thank you very much for your effort. You are 😉

And dear friend ... is this ROM eaten by Odin Flash enough and does it have recovery and other essential needs for its perfect functioning or do we have to complete it ourselves?

Can anyone write how to install this rom step by step?
I am in android 11 XXS3CUG1, T-860 original rom, rooted with Twrp.
I have downloaded
420rom_T860_C ue 1 rooted stock firmware.
It has 3 files if i unzip.
At...
Bl...
Home...
Do I select them in odin and flashed tnem in download mode I suppose?
In odin in CP & User data, I don't select anything?

After installing this go to Twrp and install in Twrp what files exactly?
I read this :
4, Flash Multidisabler then Flash the "420rom Release Kernel" image to the boot partition and then Reboot.
Where do I find 420rom release kernel? Do I still need this or it was something needed in android 10? Do I flash them in Twrp or odin? If Twrp what to select to flash in boot partition?

If anyone could write the procedure as it is now, because things have changed from the beginning, I think it would be helpful to many. The rom looks fantastic it's a shame more people can't install it.

-Do I understand correctly that master module zip file, i install it through magisk kernel when I boot in the rom?
Thanks again.

OK I reply to myself. I installed the rom. I'm not sure I did everything correctly, I may reinstall it but generally what I did:

-Using odin I installed the rooted android 11 rom version which is provided in download. Although I was already to an original Android 11 rom I installed this so to be in the same version the developer of this custome rom needs. (unzip the files in the zip, select them in odin, flash only those files). After this you will have an original android 11 rom rooted with magisk and Twrp, but no modifications or any other hack. All others steps below is exactly to flash mothers module to do the modifications / Hacks.
-rebooted in Twrp and format data (at first I didn't and I have problems so I did it afterwards)
-Boot to rom normally (boot system choise). I find magisk installed, it needed to update.
-Go to magisk install mother module (or whatever its last name is), from microsd (we have downloaded and copy it in microsd earlier) it will create a :"420rom" folder in internal.
-Boot in Twrp again and select this module zip from internal /420rom folder (or whatever is its last name) and flash it.
- Boot in rom, go to magisk, select in plugins the module 420rom.. Blabla...... it will be in the list there .
Everything should be OK.
I forgot that when we 1st install mother module in magisk it ask us many questions what we whant to install or remove etc so to create the file that we afterward install in Twrp.
Feel free to correct my little "how to", I did it by memory, whatever I was remembering but I think is simpler and newer, for someone who is in original non rooted rom.

Every time i run viper4android it says there is no driver and ask to download. I choose to download it, tablet reboot but every time the same, no drivers and ask again to download.
I have installed and checked in , magisk AUDIO MODIFICATION LIBRARY V3.5
Add V4A (MAKE SURE YOU INSTALL AUDIO MODIFICATION LIBRARY V3.5 BEFORE STARTING V4A!!! - available in Magisk Repo
Perhaps i run viper4amdroid before install AUDIO MODIFICATION LIBRARY V3.5 ?
How can i solve this?
Thanks..

when getting v4a setup - follow these steps - the rom module automatically installs the audio modification library but you may need to enable it in magisk and reboot first

1 when rom module is installed, activate the AML module in Magisk (button above the remove button) and reboot

2 when rebooted - load up V4a and let it install drivers and reboot

3 when rebooted - disable the AML module and reboot

4 when rebooted - load up V4a and let it install drivers and reboot - v4a should now be working ok

I also had to set legacy mode in settings of viper4android, I don't know if we all need this.
Thanks again.

    Changelog:

    v13

    - Install choices are in the Master Module (aka mother module) but install process is the same - the rom module will automatically pick up any choices made in the Master Module flash - end result is the same but this was a hell of a lot of work.
    - rebased to CUE1 (OneUI 3.1 and A11)
    -added power app
    -multidisabler now baked into firmware
    -a few others i have forgotten lol

    V12

    - NEW ROM MODULE SETUP BACKUP AND RESTORE - I have created a new Rom Module backup and restore function which will read the setup of the last rom module install (v12 onwards only) and ask you if you want to restore your previous install options. It will also backup any CSC features choices you make. This was not easy due to the complexity of my other function :ROFLMAO:

    - THE MODULE BASE CONVERTOR - this will now send the Rom Module to internal instead of the mother module.

    -FIRMWARE CHECK - this means that the Rom will not install unless the matching firmware to the Rom is detected (there should be no reason to mix firmwares as this causes issues)

    - VOLUME BUTTON CHOICES - I have managed to increase the timeout from 3 to 9 seconds

    -some script optimisations and tidy ups

    -CTS fix working perfectly and is included as an install option

    -everything should hopefully tidy up after itself (eg the convertor deletes itself from internal storage mid flash) but let me know if anything is out of place

    INSTALLATION INSTRUCTIONS

    YOU MUST BE ON ROOTED STOCK TO USE THE MOTHER MODULE AND ROM!


    As always it is strongly recommended to make a backup if you have TWRP installed


    Install procedure for v11.0 onwards has changed drastically as has the format of the module base itself

    From now on the N10 Series has a new install procedure but you will have exactly the same end result!!!!!!.

    There is now a "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

    There is also a 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 ;)


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


    1, Download the "Mother Module" from Downloads (Check in Telegram Group or on XDA).

    2, Flash the Mother Module in Magisk - Reboot to TWRP

    3, In TWRP, Flash Module Base Convertor located in internal/420 - this will apply all the modifications and debloat to your rom like the old Base did.

    4, Reboot and Install Rom Module in Magisk as normal located in internal/420 - all done!!!


    Install Process assuming you are coming from earlier 420rom:

    1, Download the "Odin Files", "Mother Module" and latest "420rom Release Kernel" from Downloads (Check in Telegram Group or on XDA).

    2, Using the "Odin Files" i have provided, Flash Modded BL, Modded AP, CP and HOMECSC in Odin with AUTOREBOOT off

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

    4, Flash Multidisabler then Flash the "420rom Release Kernel" image to the boot partition and then Reboot.

    5, Flash the Mother Module in Magisk - Reboot to TWRP

    6, In TWRP, Flash Module Base Convertor located in internal/420 - this will apply all the modifications and debloat to your rom like the old Base did.

    7, Reboot and Install Rom Module in Magisk as normal located in internal/420 - all done!!!

    The LTE T865 will be supported in the New V3 Rom which will be out shortly

    Hi Guys just an update for you. We had some issues with V3.0 on the T860 and T865. These have now been resolved. We had already started work on 3.1 while we were trying to fix the Tab device issues. So instead of releasing V3.0 we will be releasing V3.1, we are aiming to do this later this week. The 3.1 update is also based on the new BTF2 firmware release.

    Regards

    2 days later and still working on the V3 Rom module.

    if you have experienced poor battery life and choppy performance due to me being an idiot and leaving out oat folders, i apologise as this is now sorted.

    Therefore i am happy to report that 3minit and the wallpapers will remain in v3 and everything is working great so far!!!:D
