@dr.ketan Is there any solution for connecting a smartwatch with your ROM. I cannot connect the S3 Frontier nor the Watch 3. with both it does tuck at the last point in coupling window. I tries everything you can read about, but no trick worked so far. Maybe you got a solution. I am on S05.

Since VC9 firmware this is issue. Watch 4 working, issue with older. My watch 3 is connected to my primary device N20 and no time to factory reset and look into it. No any plan anytime soon too

There is nothing like back to ZTO because even after flashing BVO, you still will be on ZTO only. You can confirm from settings - about phone - software info - service provider software version

You are right. I updated my firmware with another country file, unlocked BL, rooted, instaleld your ROM and everything is working fine!
I appreciate having 3minit battery as part of the rom, it was a pain to install it, and I love the app.

The only thing that isn't working is Viper4Android (the main reason why I rooted!). It keeps asking to install drivers. I already tried making it install twice, tried other apps and modules (Audio library, etc.) and tried changing the .sh file as some XDA threads said. Nothing worked. Everytime I open V4A it says drivers are not installed and tries to do.

Do you have some step-by-step to make it work in S908E? If you don't, do you plan to make it work soon? V4A is the main reason several people root..

Thanks for you guidance!

As of Now Viper work only on S22 Exynos, May be Viper deveopers needs to update app for S22 SD.
Ow.. Those are terrible news. The main reason I rooted was V4A.. Is this an old problem? Did S21 snapdragon line had it already? Did they fixed for S21?

Also, are you able to fix that or it's something Viper team should work? If there is anyway I can help (testing, probably), please tell me.

I too root for the main purpose of viper4android however I've started to use wavelet which is made by the same developer. Both work and sound great on my Tab S8U and S22U. I have the SD S22U

Good morning Dr Ketan,
I recently bought his rom and also the Tweaks Pro version and I am very satisfied. I'm using a Samsung Note 20 Ultra 5G.
I would like to know if the rom could be implemented in the future with the possibility of recording Voip calls.
I use the Boaldbeast Voip recorder app which works quite well. It does not start automatically but the recordings are good.
The problem I encountered after installing Android 11 is the delay in activating up to almost twenty seconds. I am attaching the log file hoping you can give me some suggestions.
the rom also shows this message at startup: developer warning for package "com.ketan.tweaksn20pro" failed to post notification on channel "quick" See log for more details.
I will also send the log file as soon as I understand how to do it.
I am notified of updates for the rom and for the Tweaks pro app. Nothing happens when I click on the notification icon.
Thanks in advance for any suggestions and help you will want to give me.
Best regards.

Wavelet is very bad, imo. Poweramp equalizer is better, but doesn't compare to V4A. Do you get the same problem than i (drivers installation loop)?

I will keep trying to mske V4A to work. If I succeed I'll post here. I really want that app to work.

    Testing S09 Now (Based on July Security patch)

    Dirty flashed July patch firmware, seems all good.

    I didn't understand anything. I imagine *** used on rooteed phone?
    I don't know about it, nor that application allowed to discuss here
    Do I understand this correctly, that I can't 'dirty update' the base? Do I really always have to do a factory reset when going from one base firmware to the next?
    You can. search "dirty" in msg you quoted, it's explained there.
    the app rom installer don't work it's staying on this i don't know if he download rom or not i leave him for 2 hours Nothing happened
    It requires 200MB data to download and time requires depend on your internet speed.
