Hey all,

Just wiped and the weirdest thing - no access to storage at all. Any suggestions? Tried Solid explorer and Swift backup, no success. Any idies?
[Samsung Galaxy S21 Ultra] dr.ketan:
Wiped means what? Factory reset or format device?
[Samsung Galaxy S21 Ultra] dr.ketan:
If you are already on same base of your device, you can skip flahing BL and modem
[Samsung Galaxy S21 Ultra] shaharofir:
Factory reset
[Samsung Galaxy S21 Ultra] himekifee:
Do I need to flash AP?
[Samsung Galaxy S21 Ultra] dr.ketan:
That's why you needs to read installation guide.
[Samsung Galaxy S21 Ultra] dr.ketan:
Nope.
[Samsung Galaxy S21 Ultra] himekifee:
It boot loop then
[Samsung Galaxy S21 Ultra] dr.ketan:
That could be beacause of different variant, I don't have any spare time to add support for any more variant, sorry.

Ok, thanks.

Having a slight problem with the Viper install that comes with the premium donation.

Viper says enabled , audio format supported but processing is "no" while playing Spotify about BT. Anyone know a fix?

Thanks. Great ROM 👍
[Samsung Galaxy S21 Ultra] dr.ketan:
It showing processing only when you are playing music, are you sure you have enabled BT in viper?

Check with speaker too.
[Samsung Galaxy S21 Ultra] Sputnikk23:
It's not showing processing yes

The rest are healthy

oopps bricked my phone ?

I have a stock s21 ultra, not rooted, without twrp.

bootloader successfully unlocked.

successfully flashed the TWRP, but when I am in the twrp when I want to flash super.img -> when I select storage in twrp it shows USB OTG 0MB and I cannot to chose this option.

what do I need to do to see and choose the USB OTG?

which format should be the USB ? it can not be fat32 - because of super.img is 11GB, so it should be NTFS or exFat (tried both of variants doesn't work)

I also tried to push the super.img with ADB push but it says : adb: error: failed to copy: remote write failed: No space left on device.

when I try to boot to the system (android) is stuck on the Samsung galaxy screen.

please help me.....
[Samsung Galaxy S21 Ultra] dr.ketan:
ExFat should be fine

super.img is > 10GB may be you have corrupt download

Follow instructions to the letter.
[Samsung Galaxy S21 Ultra] vaymaks:
Sorry fixed the post . Super.img is actually 11gb, the md5 is same ...
[Samsung Galaxy S21 Ultra] Ssnurzel:
One question - From Time to time i'm getting massive sound stutter. I deactivated smart things which was announced to make this bug due a own equalizer.

I also dont use viper. Does someone have the same bug?

Regards
[Samsung Galaxy S21 Ultra] babyboy3265:
USB OTG always shows 0 for me as well. exFAT. However, when I press on the 0 size option, it refreshes and then loads it properly and I can flash from it without an issue. If for some strange reason it doesn't work for you still, then just use an SD card.

Got Viper fixed. Thanks.

Travelling/Roaming in Germany. Girlfriend has a S20 on same network and gets 4G. I only get 2G. Even when forcing LTE. Really annoying. I doubt it's a ROM issue. Anyone aware of a possible weak 4g antenna in these phones?
[Samsung Galaxy S21 Ultra] MasterThiefGarrett:
ok so if I have a Snapdragon 888 S21 Ultra, rooted of course, can I still use dr. Ketan's app for 'fixing' that Cameraserver wakelock stuff?
[Samsung Galaxy S21 Ultra] dr.ketan:
No. App is for exynos only
[Samsung Galaxy S21 Ultra] MasterThiefGarrett:
ok that's a shame, for me that is ;)

So nothing I can do about it then?

And here I was, thinking the SD 888 would be the better choice lol

[Samsung Galaxy S21 Ultra] babyboy3265:
Dear Doctor,

Please kindly let us know of the correct steps to safely flash the new bootloader when you release the stable version.

Also, does it matter in any way that I have separately flashed a Boot animation that removes the scary Samsung text that is shown after unlocking the bootloader?

And also, will it be ok to dirty flash?

Thank you!!
[Samsung Galaxy S21 Ultra] dr.ketan:
ROM zip will have everything inside including bootloader and how to flash.

Now ROM tool will have option to remove ugly boot animation (Exactly look like unlocked bootloader)

Unfortunately I have found a bug so relase is kept on hold till I found reason.
[Samsung Galaxy S21 Ultra] babyboy3265:

Hey Doc. the R02 is not uploaded. The mediafire link only has the R01 rom.
[Samsung Galaxy S21 Ultra] dr.ketan:
R02 is online now!

.
[Samsung Galaxy S21 Ultra] amakuramio:
flash twrp and type in multidisabler first right, its not written in guide.

after that permanently decrypted?
[Samsung Galaxy S21 Ultra] dr.ketan:
Requirement :TWRP

When you have twrp you needs to apply multidisabler. So your device is already decrypted before you flash rom and it will remain same.
[Samsung Galaxy S21 Ultra] jmac052002:
Can this rom be flashed on my s21 ultra snapdragon version? it has unlocked bootloader and I know we have to stay on on u1a baseband and u1a kernel version if it is upgraded I lose unlocked bootloader.

[Samsung Galaxy S21 Ultra] Srbija2012:
Can anyone confirm this is the right method to root a S21 Ultra from stock? @dr.ketan

1. Unlock your bootloader.

2. Download S21 Ultra: p3s.

3. Reboot to download mode

4. Put the TWRP TAR for your device with Odin in the AP slot, vbmeta_disabled_R.tar in USERDATA slot and click start.

5. Reboot to recovery via recovery key combo (Vol up + power + USB connected).

6. Disable encryption:

- Go to Advanced > Terminal, type: multidisabler.

If vendor complain about free space left on device, will attempt to resize vendor. and it ask to - Run multidisabler again!.

- Type: multidisabler again. will see - Finished. when done.

- Go back to Wipe > Format Data > type yes.

- Reboot to recovery.

7. Flash magisk apk in twrp.

8. Reboot to system, Enjoy.
[Samsung Galaxy S21 Ultra] dr.ketan:
Unlock bootloader from download mode too. You will find instructions on download mode screen itself
[Samsung Galaxy S21 Ultra] babyboy3265:
While you are in download more, you can press the volume up button once to enter open download mode, or you can HOLD volume UP to fully unlock the bootloader. So press and HOLD.

Then continue the process as per the steps. A few pages back in this thread I have shared my steps in the process of acquiring ROOT and flashing TWRP and then installing the ROM. Check it out for a touch of extra help.

Good luck!
[Samsung Galaxy S21 Ultra] babyboy3265:
I have DIRTY flashed the R02 over the R01 following the steps in both installation instruction TXT files located in the ROM R02 zip and have now been using the R02 for 2 days. Everything works fine, there were no mishaps and the upgrade went pretty smooth.

The camera has its new functionality and everything seems to work fine.

Thanks again Dr. Ketan.

Quick question as I'm not familiar with this new files filesystem structure.

What partitions do I need to restore from a complete TWRP backup to restore user apps/data (in a normal root scenario, not restoring to stock or anything) ?

Thanks
[Samsung Galaxy S21 Ultra] dr.ketan:
It requires to restore data partition but that's a very bad idea.

You should better make app backup with backup tool, e.g. SwiftBackup

Hi,

When I want to copy super.img from a win8 PC to the phone (under twrp) the windows shows an error message that this file is too big for this device (11gb unpacked) .

What can I do? I dont have a OTG cable and neither a big enough flash drive.

Thank you in advance
[Samsung Galaxy S21 Ultra] dr.ketan:
You can't copy file more than 4gb while on twrp

Installation guide have exact step, when to copy, follow it.
[Samsung Galaxy S21 Ultra] macdanger:
I have for some days now a strange problem with location services (and I apologize upfront if this is a noob question).

They seem to switch off when the phone goes to sleep. When waking the phone again - even without login in - the location service is working again. Switching the display off again (short power button or just let it go to sleep) Google Maps and other apps depending on location services give a popup message that they have problems with the location services.

I checked the following:

- Apps are not Batterie optimized.

- Location Service is on with both users (I'm using multiuser), Wifi and Bluetooth support for a more precise location are off.

- Apps are allowed to use location services always

I'm asking here because I don't know if this is a problem that might rise from a tweak of Tweaks Pro or the ROM or if this is even a problem with the ROM at all.

Thanks in advance!
[Samsung Galaxy S21 Ultra] dr.ketan:
Check TweaksPro - Toggles - Auto GPS

Turn it off in case it is On. (By default it is Off) This Toggle is intended for same thing, It disable your location when screen is Off
[Samsung Galaxy S21 Ultra] macdanger:
Thanks for this damn quick response! It was indeed turned on, I now switched it off and it seems all good :)
[Samsung Galaxy S21 Ultra] Ssnurzel:
Hi Dr. Ketan. Can you give me an advice against sound stuttering in diverse games or cracklings in videos (MX Player Pro and NewPipe)?

These issues are occurring some minutes after starting the apps.

R08 was a clean install due the same problems in R06. Only my mp3 player "Player Pro" is issuefree.

I dont use viper or other equalizers.

Energy saving is on.

Everything else is ok. No problems.

Many thanks in advance.

Regards 👋
[Samsung Galaxy S21 Ultra] dr.ketan:
If you are not using any sound mod then it's as it is from Samsung or may be hardware issue.
[Samsung Galaxy S21 Ultra] vibrantliker:
Is there a One UI 3.1.1 coming?
[Samsung Galaxy S21 Ultra] Ssnurzel:
Ok. If its from Samsung then it must be a general issue. Does someone have the same problem after activating the energy save modus?
[Samsung Galaxy S21 Ultra] dragsterman:
I was coming from stock and that point I had no OS to boot so I had to copy the ROM files from TWRP but I managed to get OTG anyway.

I would like to ask another question: the aroma installer asked wether I want to skip kernel installation or install kernel.

I dont really undertstood that because I tought the ROM uses stock kernel.

I choose to install kernel. What kernel was flashed to my device?

And sorry another question: can I make a backup of the whole system with TWRP so in case of a bootloop I can revert to that.

I know s21u have a different partition, but for example with Samsung S8 I could do a full nand backup.

Thank you in advance
[Samsung Galaxy S21 Ultra] dr.ketan:
How come no os? Whenever you wipe data, still system remains intact and device boots

Yes, flash kernel

Make super.img backup

Hey folks,

Does anyone have problems with Youtube and Google Maps randomly minimizing to PIP and Instagram's stories starting at the beginning randomly when it was halfway through the story? This is happening with a lot of people not only on Samsung smartphones.

What is odd is that if i turn off bluetooth this problem goes away (Saw this on reddit).

Any idea what might be causing this?

I'm currently in Dr. Ketan R09 ROM and did a clean install. This doesn't happen in all ROMS and some of them were dirty installed. I'm with Dr. Ketan ROM since R01.

EDIT: After clear DATA and CACHE from "Bluetooth APP" and testing, i think the problem is solved!

EDIT 2: It appears that clearing data and cache solves the issue only temporarily. Any help?​
[Samsung Galaxy S21 Ultra] dr.ketan:

SafetyNet is not passing for everyone since y'day. May be Google have patched it.

Try lsposed with x privacy Lua, someone reported it's working.

[Samsung Galaxy S21 Ultra] Sputnikk23:
Anxiously awaiting safety net fix. Will it work for R07, as I haven't updated yet?

Also quick question: when I connect to home wifi my 4g icon doesn't go away. I'm seemingly unable to cast to my chromecast when this is the case. I have to turn off mobile data. On previous phones, mobile data went away on its own.

I have the "switch to mobile data when poor performance" turned off in advanced wifi options. I checked developer options doesn't have "always leave mobile data" ticked on.

Is this a rom level feature somewhere?
[Samsung Galaxy S21 Ultra] dr.ketan:
There won't be a separate fix. I am preparing new version with September security patch and this will be mostly last A11 ROM.
