Important Instructions for setting up ROM (NEW)

- In case clean installing ROM
  • On first boot, Check for Magiak app, you may needs to update stub/Install apk manually. open magisk and complete the additional setings if asked for, else exit the magisk app. (Don't setup any option in magisk now)

(ROM Tool Essential fix also give option to install this app) There is separate SafetyNex Fix option available in ROM Tool - Mods & Misc fix - SafetyNet fix, You can use anytime if needed.
  • Now you can further setup ROM a per your liking. Also MagikHide is Configure Denylist now and available under Magisk Settings.
  • Since A12 Stable Magisk not working and new Magisk doesn't have buil-in Module repo, You can get standalone module manager from here For more details and queries about new magisk ref this (ROM Tool Essential fix also give option to install this app)
- In case dirty install (You can try if you are on DrKetan ROM previous version but we DO NOT RECOMMENDED)
  • Clear ROM Tool data
  • Before installing ROM, uninstall Magisk manager from app drawer
  • After ROM installation, update Magisk from installed stub
  • Then Follow above instruction for clean installation
  • In case you have any issue after dirty install, don't post queries on thread, we don't support dirty install, simply go with clean install.
PS : Plz don't install any other mods for SafetyNet, All queries related to Magisk/SafetyNet will be ignored if already explained above

  • If you are on A11 and updating to A12, we recommended to flash Stock firmware once, If not full, at least download your regional A12 stock firmare - Extract Home_CSC*.tar.md file and flash using Odin ith CSC tab. Also it is better if you flash CSC everytime flash updated version of ROM.
  • New base have updated bootloader so if you are running previous base, you must needs to update Bootloader & Modem else device may not boot. BL and Modem available in download area
  • Included DrKetan/Cruel kernel which is compiled with source code from cruel-kernel Thanks and credit to @ evdenis for kernel. Here is OP for kernel & source code
  • Clean Install is recommended always.
  • Don't Install any module related to SafetyNet Fix/Busybox/Multidisabler etc, Everything is included in ROM itself.
  • Magisk is built in custom kernel, SO DON'T update/flash magisk, else it will cause bootloop, In case this happens by mistake, re-run ROM zip, skip everything but Flash kernel and finish installation.
Important notes for N976B/N
  • This ROM is fully Single ROM for N975F and N976B/N and N970F ,While flashing ROM, N976 must select N976 kernel from aroma.
  • N976 may have network only after Applying ROM Tool essential fix + Reboot. ROM Tool will detect device and patch it accordingly.
  • We do not support dual SIM variant of N976 device, So you may have only one IMEI after setting up ROM. Some users reported Dual SIM working if you manually add Access Point for it.

Let me know how it goes. No one yet reported N976B
Having issues. I followed your relatively difficult to understand instructions step by step, but when I got onto the home screen my EFS was wiped, so no mobile network. Back running stock N976BXXS8HVJ1. All I want is to run your rooted ROM so I can change the gps.conf file and improve Google Maps accuracy...
plus of course have Lucky Patcher for games etc. and the ability to remove bloatware.
Surely by now, over three years after the device was released, there's a simple root solution? I've been rooting Samsungs since the S1 (GT-i9000) but never have I hit such a brick wall as this Note!

Seems first time using My ROM, Reading Changelog will be helpful instead of taking all trouble.

It will have to wait until tomorrow evening. I have work commitments starting at 6:30am tomorrow and it's now 11:00pm. At my ripe old age of 53, I need rest before driving a truck for 400 kilometres each day.

Recognized Developer / Recognized Contributor
how to add access point manually?
And i have not installed s07 on my phone. I am waiting for dual sim option.
Can anyone confirm that dual sim working on N976B.
@dr.ketan you are great Thanks for answering.❤🌹🌹
In settings - mobile network you will find access point
Select SIM you want to add then from 3 dot menu select restore default
If that doesn't work then you can add manually by typing. You needs to check other working phone's acess point settings (same operator)
Or read last few pages who did it successfully and ask for help

Hi Doc, thx. for S07! I cleared rom tool data before flashing. After flashing rom tool showed zero bytes, no function. Can I reinstall rom tool as standalone app or better reinstall ROM?

Good evening gentlemen, some news for note 10 plus in 2023? The rom is wonderful, I had problems only with nubank application that does not make the user proof when taking pictures with the front camera, I think because of root. Will the CAMERA apk receive up dates? No other very grateful and wish news for our notes 10 plus here in Brazil.
Boa noite senhores, alguma novidade para note 10 plus em 2023? A rom é maravilhosas, tive problemas apenas com aplicativo nubank que não faz a prova de usuário ao tirar foros com a camera frontal, creio que por conta do root. O apk CÂMERA receberá up dates? No demais muito grato e desejo novidades para nossos notes 10 plus aqui no Brasil.

    Good afternoon fote!

    Boy, soon after installing the version S07, you start the device, skip the steps of account setup google and samsung, only configure the wifi connection if possible, enter the app magisk that it should ask to update. Update it, go back to Magisk and if everything is ok, open the app that manages the Rom, to apply the "fix patch". If Magisk still isn't installed, restart the device and enter Magisk again, it should be ok.
    Then, enter the app that manages the rom to apply the Fix Patche, and wait for the end of the process. After, restart the device again that should already be working.

    Note: These instructions that I indicated above are in the ROM installation instructions file.
    Boa tarde fiote!

    Rapaz, logo depois de instalar a versão S07, vc inicia o aparelho, pulas as etaps de configuração de conta google e samsung, só configure a conexão wifi se for possível, entre no app magisk que ele deve pedir pra atualizar. Atualize ele, entre novamente no Magisk e, se estiver tudo ok, abra o app que gerencia a Rom, pra aplicar o "fix patche". Se o magisk ainda assim não tiver instalado, reinicie o aparelho e entre no Magisk novamente, que já deve estar ok.
    Após, entre no app que gerencia a rom para aplicar o Fix Patche, e aguarde o termino do processo. Após, reinicie o aparelho novamente que já deverá estar funcionando.

    Obs.: Essas instruções que indiquei mais acima estão no arquivo de instruções de instalação da ROM.

    Installation and Download

    Important :

    - This will void warranty.
    - As of now you will lose Samsung Pay and Samsung Pass forever if you root once, even unrooting won't help. (hope in future we can get it working on tripped knox device)
    - OTA likely won't work once you root device.

    Installation :

    Read ChangeLog post for Installation instructions

    PS : Who can handle consequences of dirty flashing, they never need to ask this question in forum. ;)
