Very good dr Ketan and people of the thread. I am not running the ROM because it takes a period longer than the factory warranty that would be lost to install it, so I ask, if it had any equipment failure, there will be a way to totally damage the software including the download mode, so much so that it cannot be detected the existence of Root ??

Bro life is short, don't worry too much... Enjoy your phone on steroids with a custom ROM.

Chances that the phone will break because it is faulty and would still turn on to show them it has been rooted, are very small.

All of these rules are made to discourage you from getting your phone to work FOR you.

Even if it wasn't rooted and it broke after a few months, chances are the seller would still find some dumb excuse not to replace it or fix it.

Samsung Galaxy S21 Ultra
For me, battery life is not so good like on Note 10+. Playing a game like Clash of Clans or looking videos results in higher battery drain. Playing Rise of Kingdoms with middle settings results in a CPU temperature of 68 degrees and very high drain. I switched the 120 hz display to ordinary 60 hz which is a bit better but in comparison to the Note 10+ the S21 Ultra consumpts too much battery. I hope that Samsung will end to use the Exynos in the next generations of smartphones.

in the instructions it says to Flash Boot loader and Modem with Odin from PC, but there is an AP file also.
Do we flash that as well in Odin?
Yes. All three parts needs to flash, Installation.txt in bootloader zip have this instructgion too.

That's why I've been praying for a custom kernel lol. I have a snapdragon note 10+ with a custom kernel and battery life is insane compared to the exynos s21 Ultra. Still doing the same usage and I easily get 2x the SOT on the snapdragon note 10+. I feel like the exynos is very power hungry and just poorly engineered as a SOC ( yep I'm aware that the s21U has a better display and more power hungry specs but I still feel that the battery is weak overall on such a high end phone)

Soooo Great!! Love that you made such a great Rom for one of the best Phones in 2021.
Also just most features that I liked most in other roms in the last 10 years..

Love it and probably this is the Reason why I will buy an S21 Ultra now my next one ;)

Also I like that you added privacy and removed the bloat ****. Looking forward to expand on this.

Keep this Alive, God and the World are very much thankful for your work :)

    Hey, has this been updated to the latest May firmware release?

    Hoping to receive my device tomorrow, can't wait!

    Wondering also if there's any telegram group, for this custom rom or s21 ultra generally?

    Hi. No, it has not been updated to May firmware, but Dr Ketan is usually pretty fast and aware of every new release.

    I'm not sure if I'm allowed to say this, but I would recommend getting the pro version, it's a way to appreciate the effort put into this.

    Regarding telegram groups, I know there are a few S21 ultra groups, but I'm not a part of any, nor this ROM has one (AFAIK)

    Wondering if someone could be so kind as to detail what each of these tweaks do, which ones may gain performance at perhaps battery cost etc. Here's my current config.

    Installation and Download & Notes


    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 won't work once you root device.
    - ROM Tool permission : Files & media - To save and read files, Calendar - Tool needs some time monitoring to avoid using RT immediately after reboot. Special access for accessibility service - Since Android 12 it requires for QS panel custom Toggl e.g. Reboot to recovery

    Installation :


    Read ChangeLog post for Installation instructions (link on post #3)

    PS : Who can handle consequences of dirty flashing, they never need to ask this question in forum. If you dirty install then handle it yourself .
