Hello Everyone.. I am loyal to Dr.Ketan software.. Whatever device he supports, I follow 😁

I have a note 10 plus with the latest R7 release installed. All is working fine. My question, is there any possible way to revert back to Q.. There are gaming apks that do not work on R.. I appreciate your help.

Thanks a lot.

Stay safe.

Even if I am using Dr.Ketan R7 rom?
Easiest Test :
Make backup of existing data
Flash Q Bootloader and modem on R07 with Odin, If odin allow it (remember, you are checking just Q BL passing or not, even if passing device won't boot before you go to next step) to flash then, again reboot to download mode and flash full Q stock firmware - reboot to stock recovery - Format data - Done.
In case Odin fail to flash Q bootloader, simply flash R bootloader (from ROM download area) and you won't lose anything on R07

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.

Edit: fixed it by myself

I have weired issue after R07, And flash also R08 but still the same.
My whatsapp icon badge is showing indicator 5 as you can see in screenshot. But there is only one unread msg. If i read that one, it goes away but the badge has 5 consistently if any new notification is arrived. It is same if i get more or less than 5 notifications.
I have tried to re install WhatsApp, also tried to wipe phone dalvic and cache, check all the settings of notifications, also clear data of oneui home launcher. But still the same.

One thing to notice, if i use another launcher like nova etc, the badge read is ok.

Can any one help what is the issue and how to resolve.

Thanks in advance.

Thanks doctor for the reply.

    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. ;)
