Hi @dr.ketan Due to hardware issues with my S21 Ultra, I've had to move to a Note 10+. Do you think you will release a version for Note 10+ on OneUI 4.0/Android 12 once it's released by Samsung in February?
Too early to say. But as of now I have no obvious reason to stop development though.
Hello ppl. Good morning.
Well here I go again....
Any thing I'm doing wrong?
What I see there is that your OEM is still locked.
You did not unlock the bootloader.

This is causing the issue. And always remember to do the key combos with the USB-C cable plugged in to your phone.

I had exactly the same troubles 2 months ago. Until I discovered that my bootloader was still locked even in the system it showed me that it was in unlocked status already.

Confusing thing is to wait for Dec security patch or Beta.
If beta update follows nov security patch then I may skip Dec security patch. Though on S10/N10 device not too much to expect on beta. TWRP mostly not going to work, even if work it will be partial just to make dump nothing else. Root on beta is always pain for these devices, but yet it was possible in past and I have provided in past. On N20/S20/S21 is quite different. Even TWRP is fully working (I needed to patch N20 TWRP though but works perfectly) and I have released full beta ROM for these devices and can be use by all users without CSC limitations. Such things I am not expecting on N10. My first aim will be to root Beta A12. Let's see how it goes.

Hello Dr. Thank you for your work. I have n976b but in phone info I can read 975f

Does that counts on the features?

Edit. To say that the aroma installer at the end of the process returns "kernel 975f installed" even if i choosed n976 in the First screens

Select mods in aroma installer you will be taken to a page to install kernels select 976 kernels for either single or dual Sim. Installer will install 975 kernel 1st then installs 976 kernel
this is what i did, twice, at the end of the process aroma, as i said, returns "kernel 975 installed" and in settings the device is named 975f

no way to get 976

ALSO, all the choices in select mod section (except for titanium and cerberus) are BLANK

can't say why

You are using a ROM that based on N975F and will remain same and won't have any ill effect, All N976 users have it same.
Regarding aroma text, ignore it if you have selected N976 kernel..

Whenever I enter Game Launcher I get that error. "An error has occurred. Please try again later."

I have tried a stock rom and I do not get that error, I have even tried other custom rom (NOBODYROM & VN-ROM).

I have the latest version available.

Hi, I need some help please.
I made a mistake
Days ago I just manually updated the Magisk to get v23 in my ROM.
But then when my phone got bootlooped I remembered that I should not do that on my Note 10. I was used to do that on my previous phones and I forgot that here its forbidden.

Is the a way
1. to get my phone working?
2. get it working without dataloss?
3. Someone already experienced that iconic stupidity and bootlooped the Note 10?

    Your CSC files are old A11, flash A12 CSC file with Odin
    I'm the person who normally never asks questions and always solves his own problems just by searching for an answer on xda or google.

    But now I have made a really stupid mistake!!!
    Instead of first flashing TWRP file with AP tab of Odin I accidentally flashed all files in bootloadermap according
    instructions of txt file in this map.

    I know it's a really stupid mistake but I can't undo it.
    The problem I now have is that my phone won't connect to my pc anymore. (USB)
    Is there anyone who can help me?

    I already tried al usual thinks like usb debugging, drivers etc..
    It shouldn't be issue. Try different cable and PC before exploring more, those are commonest cause

    try restarting your computer
    Thanks for the quick replies!
    Unfortunately, I already tried different cables and computers with no luck.

    Before flashing files in bootloader map everything was working fine and immediately after the usb connection failed so I thought this must be the cause?

    If I now connect the cable to the phone the phone starts charging. There are no other options like file transfer anymore. Turning this on in developer settings doesn't do anything?

    I will explore further.

    She below screenshot how download mode looks like. This isn't normal is it?

    ODIN MODE (By param)
    Cause: init:1 empty caller

    If you have used reboot to download from TWRP or any other option, don't use it. Instead reboot to download with Combo key only.
    If you have used reboot to download from TWRP or any other option, don't use it. Instead reboot to download with Combo key only.
    If you have used reboot to download from TWRP or any other option, don't use it. Instead reboot to download with Combo key only.
    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.

    Happy new year friends!
    Ok update on A12 - ROOTED NOW

    TWRP works but as usual N10 device always needs to boot from recovery to have root/Needs custom kernel
    As of now kernel source not available so in current scenario -

    TWRP can be used to flash zip/ROM etc but need stock recovery to have root access till custom kernel avauilable. BTW just rooted with stock recovery and it works fine.

    My plan is to prepare a ROM in few days meanwhile custom kernel available, If no sooner source code available then may release a TWRP flashable ROM that will ended with stock recovery with root working
    Let's see how samsung surprise us!

    ChangeLog S01 (A12 OneUI 4.0 for N975F/N976B/N*)

    • Based on N975FXXU7GULD jan 2022 security patch OneUI 4.0 Beta (A12)
    • SafetyNet Fix : Included in ROM Tool - Read below ROM setting up Instruction.
    • Details of ROM features available below.
    Samsung Base Chanelog
    • Android 12 OneUi 4.0 Changes
    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, don't apply any other changes before reboot
    • Again Open ROM Tool - Mods & Misc Fix - Apply SafetyNet Fix - Now SafetyNet should pass. Here same time you can apply other change from ROM Tool if requires (like statusbar option, other mods etc). You can use this app from playstore or This from Github to check SafetyNet
    • 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
    - 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.
    • Don't use (enable) Zygisk, It will cause bootloop (bootloop can be recovered by deleting data/adb/magisk.db file from TWRP). Follow above ROM setting up instructions and you will have Magisk Hide + SafetyNet fix.
    Important notes for N976B/N
    • This ROM is fully Single ROM for N975F and N976B/N ,While flashing ROM, N976 must select N976 kernel from aroma.
    • N976 may have network only after Applying ROM Tool essential fix + Reboot. ROM Tool with detect device and patch it accordingly.
    • We do not support dual SIM variant of N976 device, So you will have only one IMEI after setting up 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.
