I don't get adb popup even though I got USB option is enabled within developer option on my Note 10+ R05 build. I tried different USB cables, I can move files in between PC and phone with USB but no ADB Popup.
Settings - developer option have option to revoke authorization, try it. Possibly you accidentally denied earlier may cause it.

Really no idea how different it is from international versions. To make multi device support without having device is difficult.
It may be easier to make separate rom based on original device base. But I believe few users only have 5g version. Can't promice but may make separate rom if time permits later.
Note 10+ 5G (N976B) is listed in the title so finally the title was updated?

1. I just read the Changelog Q13 for the version that I installed for N976B and it works.
Present Rom build number: N975FXXS6DTK8
In 3 days after instalation I just noticed I don't have network internet. I did not checked this as I was using wifi.
I try to find the same problem to others in this thread but I don't find.
"4.How to reproduce error."--- this requirement I don't understand, sorry.

No internet by the network is because I forgot to backup the imei? When I first launched the rom I got the message that I don't have an IMEI but i can give calls or sms. I just bought the IMEI app from play but I can't download it. It is strange. all the other apps I can download.

Can I still do something to have back my internet via the network?
Can I get back my IMEI without the initial backup?

2. Some apps still recognize that my phone is rooted and don't want to install. I tried to hide magisk but it looks like it does not work.

3. I also want to buy the Twiks Pro for note 10 plus 5g. It will be launched soon or I can use the one from Note 10 plus?

4. In Magisk safety net does not work. It is a problem? I don't want to use Gear.

Thank you for your great work!

if you get no network on n976b ir no imei.... go to the rom tool and apply essential fix, then reboot when it says it's completed
Actually I have network. I can give calls and sms. Just the internet is not working over the network. Initially I installed one app which could not see I have imei. But in About phone info I can see my imei listed. IP address unavailable. So I'm not sure if my IMEI is affected or not but I dont know how to fix to have internet on my way. I did a clean flash of the Rom from stock.

    Recommended Installation Steps :

    Download area have txt file for Installation guide according your existing setup, follow it to the letter.

    Some Tips :

    - We Don't recommends/supports dirty flash, but one thing to note, you always should remove lockscreen & Biometric data before flashing ROM in case you gonna flash dirty.

    - MultiDisabler is require only those, who want to use stock ROM + TWRP. If you want to flash DrKetan ROM, DONT FLASH MULTIDISABLER or Any othet FIX

    - DON'T INSTALL ANY DISABLER/BT FIX/MAGISK anything after flashing ROM, as ROM already pre patched for all these stuff. Additionally flashing may cause issue.

    - You shouldn't WIPE device after flashing ROM, but It should be before flashing ROM.

    - It may take 6-7 minutes to finish installation. once installation finish, select reboot to system

    - After this first of all open magisk and check if installed correctly, If it ask for complete additional setup, let it do and reboot.

    - I recommend to disable magisk notification (Magisk - setting - superuser notification - none (This will make mods to work much faster)

    After looking magisk is installed properly, open ROM Tool and apply essential Fix - Reboot device after applying essential fix

    - If you are using Gear watch or other accessory, setup it and finish rest of personal installation.

    Done !

    Special Note for Gear wearable & Gear SPay

    Spay (Gear) working out of box (As per my test), provided you have installed required apps.
    To connect it flawlessly,
    1.Clean Install ROM + Open ROM Tool and Apply Essential Fix - Reboot
    2.Make sure Magisk manager safetyNet check pass
    3.Connect gear with Bluetooth (Gear should factory reset) and this will auto install all required apps.
    Once Gear connects, simply open Samsung Pay from Galaxy Wearable app - Hide it in Magisk Hide and you should able to add card.

    Important : If you want to use EdXposed with Gear Spay then first add your card before installing EdXposed

    I recommend clean Installation only. If you are able to handle consequences with dirty flash then proceed, but don't post bugs in forum without clean installing ROM.

    Tips,AddOn & Fix

    - 3 minit users can use 3minit battery paid version for free. Check this (Thanks to gharrington )

    - Stuck while flashing something (Bootloop), How can I reboot to download
    There is a golden rule that always works when you stuck anywhere (bootloop). Follow this -
    1.Plugin device to PC
    2.Keep holding power + vol down
    3.As soon as screen goes blank, keep holding vol up + vol down (here you needs to be quick)
    And you are in download mode.

    - Read ROM Tool - Update & Fix if any new available.

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

    R09 (For N975/N976) is Online now.
    Must read changelog above.

    Updated kernel (UF3) base

    I tried to install only the BL from Q but officially it is impossible to downgrade from R latest security patch to Q. In download mode is written check fail bootloader device:7 binary.1. pit_flash_binary unsupported version. I thought exists a way to trick the system but apparently I can't find. My big problem is not to go to Q but to enable Signature Spoofing on R which I can't. but I could do it on Q. I want to degoogle my phone.
    Did you see this
    Try this for degoogle

    sorry, i didn't know much about...signature Spoofing..
    Works like charm, as always!!
    Thx dr. for your great work.

    Best regards.

    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. ;)
