I'm getting crazy!
Somehow suddenly usb worked so I was able to install S01.
Clean flashed and it looks like everything is ok but again I lost my usb connection.

This must be a strange problem with the phone because I tried different cables and computers.
Today I had my charger port replaced and this immediately solved my problem!

I would like to say a huge THANK YOU to Dr.Ketan for his invested time in this rom and answering all the questions here at XDA!!

Viper on S01 only works until the first restart of the phone. After restart, information about incompatibility appears.

    Important Instructions for setting up ROM (NEW)

    - In case clean installing ROM
    • on first boot, open magisk and complete the additional setings if asked for, else exit the magisk app. (Don't setup any option in magisk now)
    • Then open ROM Tool, Apply essential fix and Reboot
    • After reboot SfetyNet should pass. You can use this app from playstore or This from Github to check SafetyNet. (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.
    Important notes for N970F
    • During Installation, select N970F kernel.

    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. ;)
