Hi. Everything works as a charm, but I cannot get WiFi calls to work.

It's my second full wipe and install because on the first installation I destroyed the safety net.

But in this run I'm not able to get WiFi calls working. I flashed OXM because of my version and my carrier is O2, used to work normally before.

Beside of that, how can I use multiuser? I activated it with pro app, but cannot find anything to use it.
[Samsung Galaxy S21 Ultra] dr.ketan:
Best way is to use own CSC (O2)

Multiuser should be in Settings - Accounts & Backup
[Samsung Galaxy S21 Ultra] laolaxyz:
Thanks - dirty flash and everything is working like expected :)

I am just a little bit confused that Magisk did install also as dual app - what is the porpuse ?
[Samsung Galaxy S21 Ultra] dr.ketan:
May be you missed to read changelog post about setting up rom after dirty flashing
[Samsung Galaxy S21 Ultra] laolaxyz:
actually I did - and I did it again. However I still don't understand the purpose
[Samsung Galaxy S21 Ultra] dr.ketan:
Show me both version screenshot
[Samsung Galaxy S21 Ultra] dr.ketan:
This is abnormal and not intended, something surely went wrong on your device. Anyway if you don't have any issue simply uninstall dual copies
[Samsung Galaxy S21 Ultra] laolaxyz:
okay - I did unistall the dual-app Apps and the phone is still working flawless. Thanks for your great work.
[Samsung Galaxy S21 Ultra] rah84:
Hello,

does it matter when i uninstall the Alpha Version of Magisk and install the newer Magisk canary?

and for any reason on my first install it have wiped my phone even i used the Home_CSC. I dont want that it happens again, i lost many things :( of course i used the DBT Version of HOME_CSC because my CSC is DBT

also there is a newer version of twrp. does it have bugs?

cuz the reason why i install this ROM is because the TWRP install with the newest Version dont have worked on Standard ROM, it couldnt map the data drive so i couldnt never boot to the OS.

Of course i did make use of the multidisabler but with this ROM everything works even the safetynet which i just couldnt get it passed

thanks!
[Samsung Galaxy S21 Ultra] TrevorAshley:
@dr.ketan Thanks Doc! Dirty flashed T11 over T10. No issues 🔥💯 Much Appreciated!!!
[Samsung Galaxy S21 Ultra] Immortal68:
Trying out the new T11. Update worked fine after following instructions, but I noticed a few minor bugs:

Custom fonts in the lower half of the alphabet will be selected correctly, but show a different name under Font style, e.g. Samsung Sans shows up as Samsungoneregular after selection)

Dolby Atmos is named Dolby Atom in the ROM Tools.

Dolby Atmos app crashes whenever you change the mode or turn it off/on

Dolby Atmos turns even the lowest level of sound volume very loud. An option to change steps of volume control would work against that and be very welcome in general.

Overall nothing game breaking though. Thanks for the ROM, Dr. Ketan! 😊

Hi ketan

I am currently on 4.1 Android 12. Can i dirty install 5.1 over it?
[Samsung Galaxy S21 Ultra] joseloko92:
I am unable to disable net protect on qs. It's not allowing me to comment on youtube. Says its enabled by my phone policies.

I enabled and disabled "ask fingerprint to disable net protect" but still not possible to disable.

Hi Ketan

I dirty flashed over S15. Everything seems to be working. I was wondering how I can install Magisk and it seems to be not installed. I looked for instructions but I cant find the appropriate boot.img that I need to patch as I am having the option of Select and patch a file. can you please englighten me on this? Thanks
[Samsung Galaxy S21 Ultra] dr.ketan:
Read changelog post and use magisk only from download area
[Samsung Galaxy S21 Ultra] corepda:
That's what I did. I moved from S15 which didn't have magisk, so after installing the ROM, I installed the APK from the download section. I applied an essential fix after that but the magisk is still not installed.
[Samsung Galaxy S21 Ultra] dr.ketan:
Try simply rebooting device

Still issue flash same magisk apk from twrp
[Samsung Galaxy S21 Ultra] corepda:
Hi Ketan,

This is what it says in the magisk screen. I moved from s15 which had magisk issue. So after dirty flash this is what i got. Do you recommend anything to fix this? I would appreciate it.
[Samsung Galaxy S21 Ultra] dr.ketan:
I have already told you

Alternatively easiest way

Uninstall magisk app

Dirty install ROM and install magisk apk one from download area besides ROM zip
[Samsung Galaxy S21 Ultra] corepda:
I have installed the one from download area. I can try again. Do I have to patch the AP using magisk? I am unable to enter recovery after dirty install. By the way i have followed everything per the installation guide. I'll try again. Thank you
[Samsung Galaxy S21 Ultra] dr.ketan:
No needs to patch

Simply follow guide to the letter
[Samsung Galaxy S21 Ultra] PIERO11111:
Good morning friends, does anyone have a video on how to install the rom? , I have stock rom with unlocked bootlader.

Just wanted to make sure it's for the dual sim too. Thank you, will get that tweaks pro once i've installed this rom successfully.
[Samsung Galaxy S21 Ultra] Xaro2491:
Hi. I have a question - Before i got the S21 Ultra (Exynos) with Dr. Ketans rom installed i used the Note 10+ N975F also with the rom on it. On the Note 10+, there was a metering view of my used data volume in the android drop down menu. Is there a possibility to show this data volume overview on the S21 Ultra? I use Tweaks pro. Many thanks in advance for the answer.

Regards Xaro

Hi can anyone help with Secure Folder? Every time I try and move a picture there I get an error message thanks!
[Samsung Galaxy S21 Ultra] Srbija2012:
Secure Folder can now detect inappropriate images and will no longer let you store them in there.
[Samsung Galaxy S21 Ultra] ambyy:
Good morning all.

I did a clean install. Everything is working well except MyBackup folder that will not copy from my computer to my phone storage. I have tried several methods, using ftp, zipping the file and copying but it won't extract in my phone
[Samsung Galaxy S21 Ultra] dr.ketan:
Clean install means what? Factory reset or format data?
[Samsung Galaxy S21 Ultra] Xaro2491:
Hi, is it possible to update Magisk to the newest version? Or will this cause a bootloop? And a question i asked a few days ago - How is it possible to get a view of the monthly used amount of data in the status bar?

Thanks in advance for the answer. 👋
[Samsung Galaxy S21 Ultra] dr.ketan:
You can update magisk with manager

Data volume in statusbar is broken since A11
[Samsung Galaxy S21 Ultra] Xaro2491:
Thanks Dr. 😊

Its a pity with the data volume. 😔
[Samsung Galaxy S21 Ultra] Xaro2491:
The update functioned. 👍
[Samsung Galaxy S21 Ultra] ambyy:
I formatted data
[Samsung Galaxy S21 Ultra] Ahmed Jamous:
I'm going to flash Dr. Ketan's Room, but I want to inquire about some concerns.

If I didn't root the device, means if I skip kernel flash that included magisk.

Would I be able to take advantage of the full features?

will I still receive system updates from Samsung?
[Samsung Galaxy S21 Ultra] Xaro2491:
As i know you need root for the included RomTool from Dr. Ketan.

Maybe there are also problems flashing the rom without unlocking the bootloader.
[Samsung Galaxy S21 Ultra] dr.ketan:
You can't flash any custom stuff without unlocking bootloader

ROM is prerooted. No you won't get samsung updates on custom ROM.
[Samsung Galaxy S21 Ultra] ambyy:
Doc you asked if formated data or did factory reset. I formatted data and I honestly can't copy my backup folder back to my phone. Only that backup folder.

I archived it and sent to my phone but I can't extract it in my phone.
[Samsung Galaxy S21 Ultra] dr.ketan:
There shouldn't issue if you have format data.

Try clean install again with format data.
[Samsung Galaxy S21 Ultra] dr.ketan:
Testing R05 based on UE8 (June security patch). If no major bug found then it will be public tomorrow.
[Samsung Galaxy S21 Ultra] Xaro2491:
Hi Doc. I have a problem with the homebutton. Everytime i use it it ask me to choose the standard launcher which ive chosen in the settings of the apps. Do you have an advice?

Thanks. 🙂
[Samsung Galaxy S21 Ultra] babyboy3265:
R05 uploading?

Thank you Doc!
[Samsung Galaxy S21 Ultra] losoollenos:
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 ??
[Samsung Galaxy S21 Ultra] Srbija2012:
Status = testing..

wont be long...
[Samsung Galaxy S21 Ultra] DroidHelp101:
Any plans to add support for SM-G991U ?
[Samsung Galaxy S21 Ultra] babyboy3265:
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] dr.ketan:
Now a days it's really very very hard to hard brick device. Only condition I know that easily hard brick your device is

Flashing bootloader with twrp (specially bootloader file is corrupt / wrong)

Always flash bootloader files (with md5 extension only) with odin.
[Samsung Galaxy S21 Ultra] dr.ketan:
R05 is Online now.

[Samsung Galaxy S21 Ultra] maxq1:
are there significant batt life improvements on this ROM over stock/unrooted? just asking
[Samsung Galaxy S21 Ultra] babyboy3265:
Probably not SIGNIFICANT... The Kernel is still the original. But batt life is pretty good.
[Samsung Galaxy S21 Ultra] Xaro2491:
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.
[Samsung Galaxy S21 Ultra] vibrantliker:
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?
[Samsung Galaxy S21 Ultra] dr.ketan:
Yes. All three parts needs to flash, Installation.txt in bootloader zip have this instructgion too.
[Samsung Galaxy S21 Ultra] vibrantliker:
I only flashed the BL & CP, should I go back to odin and flash just the AP, all three, or install everything from beginning again?
[Samsung Galaxy S21 Ultra] dr.ketan:
Flash Only remaining components. (AP)
[Samsung Galaxy S21 Ultra] paul_cherma:
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)
[Samsung Galaxy S21 Ultra] paul_cherma:
dirty flashed from R04 and everything works perfect !! Thanks doc. for the awesome work.
[Samsung Galaxy S21 Ultra] |||||:
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 :)
[Samsung Galaxy S21 Ultra] Srbija2012:
Why didn't you flash R05?

@paul_cherma SOT debates are just a wankfest. SOT has hundreds of variables... Screen resolution, network strength, screen brightness , background apps etc...
[Samsung Galaxy S21 Ultra] Srbija2012:
@dr.ketan I have a weird issue,.

Apps that need root, once installed don't ask for root... I revoked root access for Root File Explorer, cleared data etc, opened the app again, no prompt for root privileges...

Also installed Game Guardian, get a message that daemon could not be located.

Any ideas...

Also, apps that are already there, like adaway, work fine...

Root check app returns this status...

Phone passes safety net etc, so I'm a little confused...
[Samsung Galaxy S21 Ultra] dr.ketan:
Dirty install can cause it when magisk is updated.

Uninstall magisk manager

Reboot

Manually install magisk manager 23
[Samsung Galaxy S21 Ultra] Ahmed Jamous:
Any solution about not receiving names and numbers, (just unknown)
[Samsung Galaxy S21 Ultra] Srbija2012:

Hi, dr ketan. Thank you for R05 update. But, after dirty flash to R05, my camera seems doesn't work, it shows blank area. What should I do to fix it?

Dirty flashed R05 over R04. All works fine. Thanks Doc!
[Samsung Galaxy S21 Ultra] babyboy3265:
Those who have R05, how is your battery life compared to the May update guys?

@dr.ketan

Is it possible to have superb quality call recorder in your ROM? What about recording video calls and VoIP calls? I know newer Android versions make it difficult/impossible, but I need this feature A LOT for very personal reasons (it's extremely essential for me).
[Samsung Galaxy S21 Ultra] paul_cherma:
do you guys experience battery drain because of the "Cameraservice_worker wakelock" when walking around with the phone?
[Samsung Galaxy S21 Ultra] Srbija2012:
My standyby time, overnight, with wifi on and all notifications on is approx 5% over a 9 hour period.
[Samsung Galaxy S21 Ultra] timofonic:
I'll reply to myself.

My phone variant is SM-G998B/DS. It supports two SIM cards. I bought it in Spain.

I see Dr.Ketan's Tweaker Pro has CSC modding, this allows to enable the integrated call recording feature. I'll buy it as soon as possible if someone skilled enough or Dr.Ketan himself checks it's fully compatible with my phone variant.

I'm worried about my phone compatibility with your ROM on my S21 Ultra 5G Exynos2100 variant (SM-G998B/DS), as it's a Dual SIM one.

Has Dr.Ketan's ROM been tested in my phone variant (SM-G998B/DS)? Does dual SIM works? Any losing of functionality besides Samsung Pay and Samsung Pass and possibly Knox? I don't care of those, but I may care of the rest.

I have tried to ask on HTCMania, because more people may use my phone variant there. The website fails right now...
[Samsung Galaxy S21 Ultra] dr.ketan:
G998B dual SIM means one physical and other Esim right? If i am not wrong we all exynos S21U have same.

Regarding CSC mode, it supports 130+ country, in case it doesn't one that you have then you will have option to request add support, usually we do add support in 24 hrs. (remotely). But remember native call record doesn't support wifi call/VoIP calls.

For VoIP i am using Zoiper that have built in call recording option.
[Samsung Galaxy S21 Ultra] timofonic:
Excuse me, but that's not. It's two SIM slot (in the same piece, two sides and putting them inserted on each side) + eSIM. I provide you photos and screens screenshot as proof.

Zoiper? Does it work with latest Android versions too?

I want to use my bank app from Spain too.
[Samsung Galaxy S21 Ultra] dr.ketan:
WTF!

Never noticed SIM 1 and SIM 2 marks on sim tray. Yes, mine is same and now tested with both sim and working.

Yes, zoiper works, can't say about your banking app as it is depends on how security implemented on app, you may ask someone using that app on my rom.
[Samsung Galaxy S21 Ultra] timofonic:
Nice to know! I was afraid this was going to be an untested variant.

I wasn't able to find someone using my bank app (BBVA España). I asked in HTCmania, but maybe not enough and not in the most relevant forum section. I'll try in some Magisk forum thread in HTCmania, to see if there's some luck. I did see in XDA that BBVA Mexico app root detection can be spoofed.
[Samsung Galaxy S21 Ultra] cyclofosfamide:
I feel like a total n00b, but this is the first time this is happening to me.

I can't seem to copy super.img to my phone while booted into TWRP (?!)

I was on R03; chose to be sure and flashed BL, CP and AP with Odin. And now want to do a clean install, using method 2B (clean install, using PC).

Anyone an idea why i cannot copy super.img or any other big files to the phone, while in TWRP? Small files are not a problem, nor making folders or deleting them.

Seems like the size 11+GB is the issue?
[Samsung Galaxy S21 Ultra] dr.ketan:
You haven't followed the steps said in installation guide.

For method B you needs to first copy super.img to Int storage then from twrp, Install and then wipe

You can't copy files bigger than 4gb over twrp
[Samsung Galaxy S21 Ultra] cyclofosfamide:
Can't get into system after I flashed CP, BL and AP anymore... will it help flashing the old CP, BL, AP you included in the r03?

Looks like I locked myself out of R03 after Odin flashing the CP, BL and AP; that's what the installation.txt says.....
[Samsung Galaxy S21 Ultra] dr.ketan:
It may not allow downgrading, easy way is if you can manage for USB OTG.
[Samsung Galaxy S21 Ultra] cyclofosfamide:
Installing the image super.img from USB OTG works fine, but installing G998B_DKetanROM_R05.zip gives me errors like:

- Failed to mount '/vendor'

- Failed to mount '/product'

- Failed to mount '/odm'

Any suggestions left?
[Samsung Galaxy S21 Ultra] Srbija2012:
Ignore it...

Continue to flash the AP, BL and CP via Odin, reboot and enjoy.
[Samsung Galaxy S21 Ultra] cyclofosfamide:
After getting back to stock, installing TWRP again and following your guide, all is fine again.

So, I'm to blame. And yes... always check MD5 guys! My file was corrupt....
[Samsung Galaxy S21 Ultra] babyboy3265:
All of us here have the same phone as you. DS stands for DUAL SIM. All SM-G998B models are Dual Sim with the same DS tray like on your phone.

eSIM is on the american models of the phone with the SnapDragon processors. They have 1 physical sim and one internal non-removable one that can be used with some operators that support such a thing.

Your phone is fully compatible with this ROM. Do the reading on how to Unlock your bootloader, flash TWRP and etc so that you can understand what you are doing.

Even if you go trough all the comments in this thread only, you will learn a LOT. I personally made a whole post explaining how I went from STOCK to this ROM fully functioning, step by step.

Read up bro. Read up.
[Samsung Galaxy S21 Ultra] Xaro2491:
I also have these notices after flashing.

It can be ignored. 😊
[Samsung Galaxy S21 Ultra] sco00262:
G9980 BRI okay to flash the rom?
[Samsung Galaxy S21 Ultra] timofonic:
Thanks a lot! I wasn't aware of it, sorry.

So why there's eSIM and dual SIM menus in my phone? That's what confused me too.

Now I need to frind a way to check if BBVA España app can run on a rooted/magisk/whatever-similar device.

Okay. I'm slowly absorving information. I have busy dxays these days and was too ambitious, I'll need to be more patient. Sorry.

@dr.ketan

Any possibility to have automatic call recorder like in non-European stock ROMs? Those are the ones for Latin America, Indonesia (XID?), etc.

I want to buy Tweaker Pro ASAP, but need to wait until I get some incomes. Despite I got a high end phone, I have no money right now.

@dr.ketan you, sir, are a gem to this community! haven't tried rooting my s21u or using this rom yet though. rooted phones have much lower resale value where i'm from :(
[Samsung Galaxy S21 Ultra] babyboy3265:
Forget re-sale value bro. The market is broken and manufacturers have a big problem making new high end phones right now due to the issues in Taiwan and etc. For the moment your phone is TOP and it will stay like that probably until next year.

Do whatever you want to make your phone better and enjoy it, enjoy life as well.
[Samsung Galaxy S21 Ultra] babyboy3265:
Keep absorbing, it is a lot of info but worthy of knowing since it gives you freedom.

Your phone having both eSIM and Dual Sim menu option is some sort of mistake and likely just due to a regional bug in the software. Once you install the ROM and change the CSC (region) then the simcard options will likely just be DS.

If the S21 ultras in Indonesia are also the EXYNOS models like ours, then you should be able to install the XID region if it exists as a flashable region in the Ketan ROM. But if it doesn't, it is something the Dr. would have to include if he has the time.
[Samsung Galaxy S21 Ultra] dr.ketan:
Weird, XSG released second update within a wk. There might be a critical fix else it won't.

[Samsung Galaxy S21 Ultra] Srbija2012:
I noticed this in another forum..

Wait and see.....
[Samsung Galaxy S21 Ultra] babyboy3265:
It would make sense. There are some strange issues with the latest update.

I personally experience significantly poorer battery and also something seems wrong with the storage.

Sometimes when I take pics or videos they do not appear in the gallery properly but instead as corrupted files. Then if I reboot they re-appear. Also a similar story is occurring with screenshots, when I take a screenshot I cannot edit it and it appears corrupted in the gallery until I reboot.

The 1st time I realized that kinda issue was when most of the content in my Gallery had disappeared, I opened a file explorer and it could not find the folders and photos in the DCIM. Then it all came back after I rebooted.

These issues came up with the June update.
[Samsung Galaxy S21 Ultra] Srbija2012:
