I extracted it again and found the TWRP file, i swear it wasnt there the first time.. HAHA!

Dirty flashed, all went smoothly, thanks again @dr.ketan for a great ROM.
[Samsung Galaxy S21 Ultra] Wad12355:
Guys, is it just me or T02 has some weirdness? Clean install (2 times). Wi-Fi is not reliable anymore, if the connection a bit weak it complains that "You may have no internet", gosh that is annoying, never had before at those places (next to it iPhone works just fine). Another surprise is that the Sleep mode still has bugs, for instance in the morning, every now and then, when the alarm goes off the Stop button is missing.... so have to force to restart the phone.
[Samsung Galaxy S21 Ultra] Energixia:
@Wad12355 Here there are not any issues with this wonderful work.

Try to start from the beginning using Odin and after that install this Rom.

Let me know ;)
[Samsung Galaxy S21 Ultra] Wad12355:
Thanks for getting back to me so fast, mate. I see the problem is on my side; never mind, even though it is a pain in the neck to re-install everything from scratch, I'll give it a shot.
[Samsung Galaxy S21 Ultra] Srbija2012:
You may need to do a full factory reset, start clean, and see how it goes.. I find T02 very fast, smooth, and have no issues thus far.

OR

Reset network settings

OR

Change the channel your router is using, sometimes that can help.
[Samsung Galaxy S21 Ultra] Energixia:
@Wad12355 it's a pleasure 🙏
[Samsung Galaxy S21 Ultra] paul_cherma:
hey guys, need some help here. I messed up something during ROM installation and wanted to flash stock firmware using Odin and then start the process again. I downloaded the latest firmware using Frija tool (Model G998B, CSC: BTU). First of all is that the correct CSC to put in Frija or doesn't matter? This is the error I'm getting in Odin. I think it is saying I am using an older bootloader but I'm not sure so was wondering how can I go back to stock firmware and then try to install the ROM again?

Edit: I am still able to get to TWRP if I need to do something from there.
[Samsung Galaxy S21 Ultra] Srbija2012:
Why not try and flash the rom again, following the clean install instructions, factory reset etc... Don't forget to flash the BL, AP files etc as provided in the zip.
[Samsung Galaxy S21 Ultra] marcjuh:
If youre trying to get back to older patched rom with older bl and modem...forget it, you cant go back...the csc doesnt matter...you can always select the right country in setup rom. So try to download latest released rom frija and flash accordingly.
[Samsung Galaxy S21 Ultra] czar22:
nice work

it is SM-G998B compatible ?

or any version soon ?
[Samsung Galaxy S21 Ultra] dr.ketan:
Title of the thread isn't self explanatory?
[Samsung Galaxy S21 Ultra] dr.ketan:
In friza put csc DBT then you will get latest firmware same as R03 base
[Samsung Galaxy S21 Ultra] paul_cherma:
Thanks for the replies guys. I was able to get back to stock using INU as CSC actually and now I am rooted and installed the ROM also
[Samsung Galaxy S21 Ultra] paul_cherma:
Is there any way I can disable remote support in device settings? Any time I click it it downloads smart tutor apps from playstore and wanted to disable it with adb but I'm not sure what the package name would be. I am using t-mobile on this phone if that helps.
[Samsung Galaxy S21 Ultra] AuzzyPunk:
Hi, will this rom fix galaxy wearables? Like allows things such as galaxy watch being paired?

Thanks :)
[Samsung Galaxy S21 Ultra] Srbija2012:
My Galaxy Watch (R800) has no issues pairing with this rom.
[Samsung Galaxy S21 Ultra] Srbija2012:
I don't even have that option..

1. Will this update use the Same super.img file as R03? If so, saves me from copy and pasting to my phone again...

2. Dirty flash AOK?

[Samsung Galaxy S21 Ultra] marcjuh:
Greatly tnx dr ketan for keeping this new phone alive...i realy appreciate it.
[Samsung Galaxy S21 Ultra] Srbija2012:
@dr.ketan same super.img as R03, or does it need the new one.
[Samsung Galaxy S21 Ultra] Brucio84:
@dr.ketan were you able to solve the problem in transferring files with secure folder?
[Samsung Galaxy S21 Ultra] paul_cherma:
thanks for the instructions, I got it working finally. Just a weird issue i'm having, I copied the presets to data/viper/files folder but I can not get them to load. Or even when I create the preset and save it, it doesn't show up. Any way I can fix that?
[Samsung Galaxy S21 Ultra] dr.ketan:
Haven't look into it yet.

Super.img is main ROM (base)
[Samsung Galaxy S21 Ultra] Srbija2012:
Confirm dirty flash from R03 to R04 went smoothly.. no issues...
[Samsung Galaxy S21 Ultra] pardisgraphic:
Hello doctor, please enable these items in the next ROM if possible

Camera shutter sound menu

Screenshots in secure apps
[Samsung Galaxy S21 Ultra] jhr5474:
These are both features that work with the pro version, I know for sure the csc features for shutter sound is there and I'm pretty sure screnshot also is there. So you would need to pay like the rest if us that are using this feature. Cool thing about it is you get to use it on other roms as long as you keep the same phone.
[Samsung Galaxy S21 Ultra] fission6606:

-My Process is good ?

Thx for your help and your job for the comunity
[Samsung Galaxy S21 Ultra] dr.ketan:
Download area (beside rom zip) have detailed installation guide, go through it.

There is possibility of dirty install (without losing data) also mentioned in guide but it is always recommended to make backup of important data incase dirty install doesn't go as intended and needs to to wipe data.
[Samsung Galaxy S21 Ultra] Fznshk:
Hello,

I clean installed(without wiping storage) t02 and I'm facing annoying vibration problems.

My phone vibrates for about 3 seconds when I toggle a setting(example turn off wifi from settings, not quick toggle)

When I close all app from the menu, it vibrates for a few seconds.

When I scroll in an app, example WhatsApp and the scroll is completed and nothing to scroll(but I still try to) there's vibration for 4 seconds.

It's super annoying. It gets fixed when I disable touch integrations from system vibration settings.

But I don't want to completely disable it. I want to get rid off the vibrant which didn't exist in oneui 4.

I think it's a bug.

Also, call connect vibration doesn't work even though the setting is enabled. Any help would be appreciated. Thanks.
[Samsung Galaxy S21 Ultra] dr.ketan:
Try installing nice catch good Lock module to find what app causing unwanted vibration
[Samsung Galaxy S21 Ultra] Fznshk:
Sorry, I forgot to mention. I already tried that.

But there are absolutely no logs for these kind of vibrations.

Thanks a lot for the quick reply.
[Samsung Galaxy S21 Ultra] Tristan17:
Has official version come out yet or still in testing?
[Samsung Galaxy S21 Ultra] founchki:
official is out, it's T02
[Samsung Galaxy S21 Ultra] Fznshk:
Any solution please?

I've already tried nice catch app but it doesn't log anything for such vibrations.

Thanks.
[Samsung Galaxy S21 Ultra] dr.ketan:
Nothing can be suggested with provided info. Best way factory reset and don't install or login any account for few hrs and see if that fix issue. If that fixed then you needs to find out one of your app/setting causing it.
[Samsung Galaxy S21 Ultra] jhr5474:
Is it possible to run this rom uprooted for a few days? I have a app I will be using for Christmas stuff and It won't run on this rom regardless of what I hide
[Samsung Galaxy S21 Ultra] dr.ketan:
Try uninstalling magisk app and see if that works. Install magisk apk when needs it back
[Samsung Galaxy S21 Ultra] jhr5474:
Thank you
[Samsung Galaxy S21 Ultra] Sputnikk23:
Just installed the latest. Can someone explain why my camera cutout is so large and off center ? i had this problem several releases ago and thought it would go away with a clean updated install. I use tweaks pro and did the hide bootloader patch on both installs. Is it possible some mod is doing this? Camera cut out options to disable in specific apps doesnt seem to respond either.￼
[Samsung Galaxy S21 Ultra] Srbija2012:
Does it do this with the stock OneUI Launcher?
[Samsung Galaxy S21 Ultra] Sputnikk23:
Yeah. I use Microsoft Launcher. I tried switching default Launcher back to oneui and rebooted

It's there on every app.

Edit: reflashed bootloader and csc from super.img - still the same

Edit #2: uninstalled tweakspro. reflashed same super.img and the setup zip - still the same
[Samsung Galaxy S21 Ultra] yomyself:
open the camera app and go full in the settings on top of the display, this will hide any cutout or program modifying the statusbar.

Or use safe mode

First, completely power off the phone

Turn on the device and when the Samsung logo appears, press and hold the Volume down key.

if done correctly, "Safe mode" will display on the bottom left corner of the screen. If "Safe mode" does not appear, repeat the previous steps

if the problem not disappear maybe is something physical, looks like the screen is broken on the camera cutout from your posted pic.

Sorry for my english
[Samsung Galaxy S21 Ultra] dr.ketan:
Safe mode can fix if issue is related to user app, system app still remain same. So if happened with some system mod it can not fix in safemode

This kind of issue usually related to DPI or modules (magisk/exposed/lsposed) so worth to try that. Though safemode will auto disable magisk modules so first only disable module will be further helpful to narrow down issue. If that doesn't fix then better to try with safemode
[Samsung Galaxy S21 Ultra] Sputnikk23:
Camera in full still shows it. Safe mode displays it. And its even in TWRP. There is no crack. If you mean the straight line from left to right, thats a slightly small screen protector.
[Samsung Galaxy S21 Ultra] Sputnikk23:
No modules installed in lsposed. Magisk shows none and fox's has "Zygisk - LSPosed" and "Universal SafetyNet Fix" (by kdragon). I didn't install those so I assume they came with the rom.
[Samsung Galaxy S21 Ultra] dr.ketan:
If appears in twrp then likely hardware related
[Samsung Galaxy S21 Ultra] marcinx89:
I have installed Youtube vanced from ROM tool S21.

It works but its often very sluggish keep loading video endless time you need to click another video then go back to previous one then it might be playing.

[edit}

I had reinstalled it. Figured it out it only sluggish once i log into my yt account.

P.S Thanks to dr.ketan for hard work.

I'm having some difficulties to use some app which check safety. I've passed Safety Net Test.

My bank app detected my phone is rooted but I was allowed to install it and use.

1. I can't use Success Factors app for example. It says "Your device must meet security requirements"

SAP SuccessFactors Mobile - Apps on Google Play

Stay connected to your business with SAP SuccessFactors.

play.google.com

Is any solution to that?

2. I love call recording feature but would be possible to record phones calls out of Whats App and Messenger?
[Samsung Galaxy S21 Ultra] Wad12355:
1. Go to Magisk/Settings/Configure DenyList "tick" your "sensitive apps". 2. You may hide Magisk itself (look up for hide Magisk and follow the steps).

EDIT

It was a stupid mistake, just messed Odin files.

Sorry to bother everyone...

Dear Dr. Ketan, I'm writing to ask for some help regarding the installation process of your latest rom.

I was already using the version S12 of your creation. Today I tried to install the T03 version.

At 1st I tried to install the rom only with a factory reset, and tried to follow step by step your instructions. As I had some doubts regarding my specific CSC region, I chose not to change it during installation.

Apparently everything went OK, but when I tried to boot into system my device rebooted 3 times before succeeding.

And after that neither bluetooth or Wi-Fi were working.

I try then to do another clean install, this time formatting data completely.

The result was absolutely the same.

Just to check, I tried another clean install formatting data, this time flashing the CSC file. Again, after some reboots the device booted finally but without Bluetooth and Wi-Fi.

Just to be clear, every time I flashed the bootloader and modern through odin as instructed.

I'm sure I'm doing some kind of mistake, but I cannot find what is my error. Can you please give me some advice? Or some other experienced user here?

Thank you so much!!
[Samsung Galaxy S21 Ultra] kchalos:
Dear Dr. Ketan, I tried the T03 android 13, but I had many problems when restoring the backup using "totanium backup", it restores it but it does NOT open the applications, so I have to delete the cache / data of the apk and just I can run the applications (I understand that it's like a security system of Android 13 itself), what I don't like is that you can't use the Data and OBB folders, in Android 13, I'm really using those folders in Android 12 For games and my stuff, that's why I chose to go back to Android 12 One UI 4.1 "Rom S15", unfortunately the little I was in A13 seemed worth it but it has many cons, so Android12 will continue :(.

* Sorry if you don't understand, use "Google Translator" my native language is Spanish :) Regards.
[Samsung Galaxy S21 Ultra] dr.ketan:
You are using an outdated software Titanium Backup.

Move to better software e.g. SwiftBackup. or other working on A13

I have to reboot the phone and within the first 5 minutes I'll be allowed to do it then I'm restricted to modify the APN settings. Please advise.

Hi, thanks for the great and ongoing work!

I am on S14 and downloaded T04 now.

Found the installation.txt in "BL_DrKetan_G998BXXS5DVL3_CP_G998BXXU5DVL2_Extract_This" related to Odin, but can't find any installation guide in "G998B_DrKetanROM_T04_VL3_extract_this".

Until S14 I know your PDF documents with detailed (and really helpful) step-by-step instruction for when to do what.

What did I wrong or where can I find the mentioned installation text?

Or is it sufficient to flash with Odin and just install the "G998B_DrKetanROM_SetUp_T04.zip"?
