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?

(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.

    • 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.

    PS : This is a fully customized ROM and for end users only, ROM or any part of ROM not allowed to redistribute,modify or to use as base to prepare new ROM.

    STATUS : Online
    Does anyone feel, once you installed the any Rom, that Wifi and network signal is better?
    I haven't installed any roms yet on my note10+ to keep knox but i'm just wondering if it fixes these issues.
    ROM doesn't do anything to improve network, so don't expect even 0.1% improvement on that stuff. Features only you get with ROM are mentioned in changelog post.

    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. ;)
