I tried everything but only the videos are there, all images are gone. I tried accessing them with different file explorers , there's nothing to be found. I'm not sure how they disappeared because I didn't delete anything. Was searching earlier the Samsung forums, there's a good amount of people who have had the same issue with Samsung devices. Not sure if the storage is corrupted or what might have happened but so far I can't find the pics
[Samsung Galaxy S21 Ultra] paul_cherma:
I installed R07 again in hopes to fix the issue but still the pics are not showing up. @dr.ketan I see that you have mentioned something in the installation guide about int. storage might become unreadable. Do you think I might be having that issue ? Will factory resetting and installing tweaks pro fix it?
[Samsung Galaxy S21 Ultra] dr.ketan:
If you flash rom with factory reset (which preserves media files) instead of format data (which deletes everything on Int storage), all files on Int storage will be non readable (files will be there but it won't open/execute

Yes, TweaksPro have workaround for it, still it is Experimental but working for me always(Since last three version, I have installed rom with factory reset +fix only) and none other users also not reported any issue though.

Fix will work only if it happened with factory reset issue, if it happened with some other bug, it won't work. If you are not able to see files at all then your issue is different
[Samsung Galaxy S21 Ultra] paul_cherma:
I see, thank you for the info. I have only used the dirty flash method so maybe my issue is different.
[Samsung Galaxy S21 Ultra] babyboy3265:
Realistically the issue you are describing seems like it was fixable easier but you tried to move the files before the "corruption" was fixed. The moving may have created some other issue entirely.

Try something else... Download a file manager like X-plore and go to the settings and turn on SHOW HIDDEN FILES. Check if you can see some strange files or folders that appear hidden.

Then you can also go to the folder you moved your files to, and press DISK MAP. Look at the size and try to understand if it makes sense. If a folder seems empty but the size it large, there must be something else there. Maybe the files became SYSTEM HIDDEN instead of normal hidden.
[Samsung Galaxy S21 Ultra] paul_cherma:
I am using Mi-Xplorer but the JPG files are gone. Even when I turn on the "show hidden files" option. I still have that corrupted file spinning and I still can't delete it. I have many other folders with pics. in my internal storage and they are still there, they didn't "disappear" or got deleted. What is surprising the hell out of me is the fact that all the JPG pictures taken with the stock camera and GCam that were located in the original DCIM/Camera folder are gone and the videos which I recorded with Gcam and Stock camera are still there. The only way I can explain what happened is maybe the internal storage tried to fix that corrupted image that was processing continuously (and still is btw) by deleting it , and in the process, it deleted all the image files that were/came from the default DCIM/Camera folder. My mistake was moving those files within the same storage, I should have moved them to my laptop instead. I am running out of options on how to get those pics. back so I'm thinking to do a hard reset of the phone and maybe hope to get some of the pics back with some recovery software.

I remember the size of the folder where I moved the pics and videos. It used to be almost 8 GB, now it is 3.4 GB because all the pics are gone and only the videos are still there.

[Samsung Galaxy S21 Ultra] babyboy3265:
Tough cookie for me bud! I hope someone else here has more experience with the matter...

Could you however, try some of the higher rated recovery software from now, before you try to reset the phone?
[Samsung Galaxy S21 Ultra] paul_cherma:
I tried a few, they couldn't even find a single one from more than 700 pictures that disappeared. It's as if I never even took those pictures. Usually with the recovery software I can find a few of the pics that were deleted/lost but this time nothing...
[Samsung Galaxy S21 Ultra] babyboy3265:
have you tried checking the trash folder in Gallery?
[Samsung Galaxy S21 Ultra] paul_cherma:
yep, checked there several times. Nothing there
[Samsung Galaxy S21 Ultra] Srbija2012:
I've had issues where some photos didn't show up, and using a 3rd party app fixed it, but never heard of this issue where photos disappear.

Hope you get it sorted soon..
[Samsung Galaxy S21 Ultra] paul_cherma:
I think they're gone forever at this point. Even installing disk digger and doing a search with it., I was able to see that a few pics that I deleted a few months ago were restorable. But not a single one of the ones that were deleted recently come up with all the recovery softwares that I have used. it is as if I never even took those pics...
[Samsung Galaxy S21 Ultra] babyboy3265:
It really sounds like as if they were moved somewhere else and not deleted...
[Samsung Galaxy S21 Ultra] Srbija2012:
Amuse me.. Go to MY FILES, click on the 3 dots and select SHOW HIDDEN FOLDERS.

They might magically appear.. I doubt it, but worth a try.
[Samsung Galaxy S21 Ultra] SuperMaximus:
Is DEX working in Dr. Ketan ROM? Is it possible to run Dex in rooted stock ROM? Looks like both SmartView & Dex stopped working after root :(
[Samsung Galaxy S21 Ultra] marcjuh:
Plse copy the entire dcim folder to pc...no matter what it says...format in twrp and flash rom like in downloadfolder copy back to internal storage and see if phone can see them ...
[Samsung Galaxy S21 Ultra] dr.ketan:
No idea about stock rooted but both working on DrKetan Rom
[Samsung Galaxy S21 Ultra] SuperMaximus:
Dr. Ketan, now I'm using SM-G998BZKHSEK phone intended for Ukraine market. Phone is rooted & I installed TWRP. I would like to flash your ROM, but need my carrier's aggregation to work properly. As I understand your ROM is built based on different region. Please advise how can I flawlessly flash it.

What did you do to make DEX/SmartView work with Knox ticked?

Did you adjust

build.prop with

"wlan.wfd.hdcp = disable"

?
[Samsung Galaxy S21 Ultra] paul_cherma:
What should I format in TWRP ? The DCIM folder or what ? The folder size has decreased in size since the pictures are not there anymore, I remember it being bigger in size before the pictures disappeared/got deleted/ were lost.
[Samsung Galaxy S21 Ultra] SuperMaximus:
build.prop a parameter

"wlan.wfd.hdcp = disable"

Worked like a charm!
[Samsung Galaxy S21 Ultra] hedoujeff02:
Does anyone have a problem when you make a call? Every time, I'm trying to call someone but it always showed me that CALL CAN'T CONNECT. But after a couple of tries, it connected. Anyone knows how to fix it
[Samsung Galaxy S21 Ultra] marcjuh:
Plse install rom clean like the install text says in install zip....
[Samsung Galaxy S21 Ultra] Srbija2012:
Did the photos show up in your PC once you copied them from your phone? If so, thats good news..

Id suggest doing a full factory reset, and reinstalling the ROM from scratch, something went wrong somewhere..

Let us know how you go.

Boring while waiting for A12
[Samsung Galaxy S21 Ultra] babyboy3265:
A12 Doc?
[Samsung Galaxy S21 Ultra] paul_cherma:
did another search using disk digger, this time only the thumbnails of the pics showed up. Each one of them was between 4-7 kb so once you zoom in they're heavily pixelalted and blurry. But no, they didn't show up when I copied them from the phone to the PC
[Samsung Galaxy S21 Ultra] Srbija2012:
**** dude.... Sounds like they are long gone..

Factory reset time, and start over mate... As soon as you have, test the camera and check that pics are being saved..
[Samsung Galaxy S21 Ultra] Srbija2012:
Android 12
[Samsung Galaxy S21 Ultra] Srbija2012:
Haha... The life of a dev huh..
[Samsung Galaxy S21 Ultra] paul_cherma:
I think it's pretty much impossible now that I'm doing further research on this topic. Since around android 6.0 they havve implemented file based encryption, and deleting a file deletes its unique encryption key. That makes it impossible to recover. that's why I'm only able to recover thumbnails, they are stored differently but the pics themselves are gone...
[Samsung Galaxy S21 Ultra] Srbija2012:
Have you done a FR and tested if pics are saved on your phone...?
[Samsung Galaxy S21 Ultra] Srbija2012:
HSBC app is hidden, Magisk is hidden and renamed, phone passes safety net check, but still get this message... Any way to fix it @dr.ketan ?
[Samsung Galaxy S21 Ultra] babyboy3265:
If you opened the app before you hid it, maybe it logged it. Can you clear the app's data?

And in the magisk hide, did you hide ALL the components of the app? And also Google play services and its components as well...
[Samsung Galaxy S21 Ultra] Srbija2012:
Yes to everything brother ...
[Samsung Galaxy S21 Ultra] babyboy3265:
Ah.. Let's hope the Doc. can help then..
[Samsung Galaxy S21 Ultra] naya28:
Hellow Doc, pleased to see U here but I ve a problem.

Unlocked bootloader and intalled twrp as explained but i m not abble to put the super img file on my internal memory.

I VE formatted data and i m able to put the rom zip file but not the img.

I dont understand.

Thanks for your help.

Maybee i can use my note 9 to do usb otg but i dont know how😔
[Samsung Galaxy S21 Ultra] shaharofir:
You can't move the file due to its size. Transfer it via a different ROM.
[Samsung Galaxy S21 Ultra] dr.ketan:
Installation instructions have steps when exactly you need to transfer. Just follow it. If you have already loaded stock rom then once boot on stock rom and then follow instructions
[Samsung Galaxy S21 Ultra] Srbija2012:
The latest security patch has just been released for the Galaxy S21, Galaxy S21+, and Galaxy S21 Ultra.

The new build carrying the August 2021 security patch comes with firmware version G99x0ZCU2AUGE, (China etc, not Europe/Australia yet for the G998, but cant be far away) and the update for the S21 Ultra requires a download of about 300MB.

300MB doesnt seem like anything major.
[Samsung Galaxy S21 Ultra] babyboy3265:
I think your problem is that you are not pressing the right button.

When the moment comes that you should install the SUPER.IMG, you have to press the button on the right bottom side, where it says "Install image". Then select the SUPER.IMG file and tick the SUPER box, then install it. After that install the ROM.ZIP file. When you press the button "install image", TWRP starts looking at IMG file extensions and not ZIP files.

Write here if this worked for you or not.

And if the case really is that you can not copy the SUPER.IMG file to your phones memory, you can try to use a USB stick like I do, and install everything from the USB. I never copy the files to the phone memory.
[Samsung Galaxy S21 Ultra] naya28:
I m not able to push the image file in internal memory.

I m running beyond rom so i will try toonight.if I can t i will buy an usb otg cable.

Thanks for your help Sir.

Ps @The Doc ,we have to format data after installing twrp if i m right, so no os on the phone.

I will find solution.

Have a nice day
[Samsung Galaxy S21 Ultra] babyboy3265:
You could also look for this USB stick that I am using. It is exxtremely useful as it is normal usb port on the 1 side, and USB-C on the other side. So if you format it as exFAT and NOT FAT32, it can fit any size files, including the SUPER.IMG.

SanDisk Ultra Dual USB Type-C Laufwerk Smartphone Speicher 128 GB: Amazon.de: Computer & Zubehör

SanDisk Ultra Dual USB Type-C Laufwerk Smartphone Speicher 128 GB: Amazon.de: Computer & Zubehör

www.amazon.de
[Samsung Galaxy S21 Ultra] dr.ketan:
Still you are not getting. You can not transfer any file >4GB while on TWRP

Formatting data wipes dta only, still you will have os installed.

If you read and follow installation guide carefully and follow to the letter, you can flash ROM (including super.img) without having USB OTG too.
[Samsung Galaxy S21 Ultra] naya28:
So stupid I am

I just have to download now your package

And do it toonight.

Thank you

It seems a Magisk fork by @vvb2060 is experimenting ways to better hide root against banking apps. Here is the relevant forum thread, if you want to look at it.

Here's the fork: https://github.com/vvb2060/Magisk

@pndwal posts are quite informative. It seems the fork author uses Telegram to post Alphas, but I avoid to use too much communication channels and prefer this fork gets more popular or merged back to another more popular one (upstream or another fork with English documentation, I understand the sentimental reasons of the author for using Chinese but it's a major hindrance).

I use banking apps heavily, this scares me and hope community solves it. It's essential for Android modding community to hide root as best as possible, IMHO.
[Samsung Galaxy S21 Ultra] naya28:
Failed I don t have stock rom anymore but beyond.

Can I wipe the super partition because the only way is to format data to install a rom.

I missed something but what?

Instructions are easy but...
[Samsung Galaxy S21 Ultra] dr.ketan:
Copy and dirty flash super.img on existing rom

Format data

Copy rom zip (you can copy in twrp) and flash

Flash bootloader and modem

Done
[Samsung Galaxy S21 Ultra] naya28:
Invalid argument for mounting everything.I ran in bootloop.

On the rom I saw there is no unlock oem option.

Maybee that.
[Samsung Galaxy S21 Ultra] dr.ketan:
No idea what you are messing up

I'd suggest to keep installation guide open and follow it to the letter

Aliso make sure your download file isn't corrupt and device is G998B
[Samsung Galaxy S21 Ultra] naya28:
Device is ok but how could a file be corrupt?

This is the 2 time that i download it.

It can be the unarchiever?

Witch one do you use and can I check md5 for img.file.

I reinstalled beyond again without any problèm.

I think i m gonna put th pgone in stock again and retry.

Thanks 4 your job and your help
[Samsung Galaxy S21 Ultra] naya28:
Ah sorry one question again

10.4 gb is normal for the img.file?
[Samsung Galaxy S21 Ultra] Ssnurzel:
For the Super.img file - yes. 10.94 gb.
[Samsung Galaxy S21 Ultra] babyboy3265:
Sometimes files get corrupted when you are downloading them.

However, when you extract them from the ZIP file they should give you an error if they are corrupted. To be extra safe you can also use a download manager like uGET(open source and free), which is the one I use. It is stable, files don't break and it also manages to pull out much faster downloads than the standards browser downloader. If you use it, make sure you max out the CONNECTIONS to 16 when you are about to start the download in the dialogue.

Brand new clean flash. Unable to find the call record option in phone --> 3 dots as described on website. Is Tweaks Pro required for this?

Also, 3Clock doesn't work in center mode?
[Samsung Galaxy S21 Ultra] Srbija2012:
Open Rom tool, go to Mods & Misc Fix, Click on Auto Call Record, reboot.
[Samsung Galaxy S21 Ultra] Sputnikk23:
Oh I thought that implied it would automatically record all calls. Thanks.
[Samsung Galaxy S21 Ultra] Srbija2012:
All good champ...
[Samsung Galaxy S21 Ultra] Sputnikk23:
Sorry, after testing to be clear for anyone who seeks the same info:

Call record doesn't come up like it used to ( at least on my S9 ).

YOU DO NOT NEED TO CLICK AUTO CALL RECORD IN ROM TOOLS.

The record option is found in the 3 dot menu AFTER A CALL IS STARTED.
[Samsung Galaxy S21 Ultra] Srbija2012:
Yep, you can either have it record every call automatically, via the fix in Rom tools, as I have, or use the 3 dot manual mode..

I assumed you wanted AUTO CR hence my instructions because you wrote 'Oh I thought that implied it would automatically record all calls'..

Automatically is not triggering the record feature via the 3 dots..

Cheers
[Samsung Galaxy S21 Ultra] dr.ketan:
If you guys read Changelog, it's already been mentioned about

- Auto Call record

- Manual Call record

Both are working without CSC restrictions.
[Samsung Galaxy S21 Ultra] Srbija2012:
Yeah I understand the difference.. cheers...

August update out for DBT.
[Samsung Galaxy S21 Ultra] Sputnikk23:
It just wasn't immediately clear where to find the option. Great ROM. Everything working out of the box so far. Sent a donation there for Tweaks Pro.

Question, is camera shutter sound option missing from this ROM?
[Samsung Galaxy S21 Ultra] dr.ketan:
Auto call record in setting menu

Camera shutter sound

Both are csc features and this rom doesn't touch any csc files

But as you stated, you have already request for TweaksPro, then you will have options to tweak csc features with TweaksPro

John was hired by Google, right?

If so, I think it's too naive to believe he will release new and proper Magisk releases. Forget about that, Google empire hates rooting and everyone will see it soon.

I already mentioned a promising Magisk fork, with certain advantages. It's in alpha status, but I hope an unfork effort happens soon for the good of the community.
[Samsung Galaxy S21 Ultra] dr.ketan:
No, that's not the case

Google doesn't have problem with magisk but Magisk hide.

So I believe, rooting won't be affected but we may not have benefit of John's experience on Magisk hide, we may have to look into xposed/lsposed for magisk hide like stuff.
[Samsung Galaxy S21 Ultra] infoenekas:
Hi Dr. Has the problem of transfer of the file to the secure folder been solved in the last version?
[Samsung Galaxy S21 Ultra] timofonic:
I see. But main Magisk repo hasn't been updated. There are many active forks.

LSPosed seems interesting, but too many addons that may not work so okay.

Hello

How can we switch from r07 to r08 without deleting everything?
[Samsung Galaxy S21 Ultra] babyboy3265:
There are instructions in the "INSTRUCTIONS" file, which you can find in the ZIP file that contains the ROM. Follow the "dirty installation" part and you should be alright.
[Samsung Galaxy S21 Ultra] babyboy3265:
For the 1st time now I am noticing significantly poorer performance since the latest update. Lags and big frame drops when scrolling/browsing. Apps sometimes bug and start running at what feels like 30fps. If I close them they start working with the 120 again... Something is wrong.
[Samsung Galaxy S21 Ultra] Srbija2012:
@babyboy3265 Can't say I've noticed anything like this mate... Something doesn't sound right ..

No issues like that after dirty flashing..

Maybe try to delete the cache and dalvik cache again...

Hi @dr.ketan.

The problem of file transfer to the secure folder persists. Will you be able to solve it in the next update?
[Samsung Galaxy S21 Ultra] babyboy3265:
Did that at the time of the installation of the latest build.

Out of curiosity after posting here, I cleared up the memory and etc with the optimize button in the settings, it got got faster, for now. Maybe it was just an overload, lets see.
[Samsung Galaxy S21 Ultra] bartjeh1991:
Okay, installed the rom a few days ago.

All seems pretty stable, SOT increased again by a lot!

A few months ago the phone was getting almost 10 hours SOT. Last months it was like 5-6 hours. Now after installing rom and some tweaks. The phone feels like that again. Last night 7 hours SOT with almost 30% battery left. Loving my S21 again!

Thanks ketan ❤️
[Samsung Galaxy S21 Ultra] TeoZe:
Hello,

I recently downloaded this rom and I am quite happy with it. I didn't had any issues while installing.

The only thon that is bugging me is the Camera wakelock fix. It disables all the sensors (with the tile) when the screen is off but often I find myself manually deactivating it when I want to take a picture. Especially right after unlocking the device.

Somehow it sometimes doesn't reenables all sensors (deactivates the tile) when I turn on the screen.

Anyone also experiencing this issue

Can the new Twrp flashed as update without full wipe? I"m running R07 yet.

[Samsung Galaxy S21 Ultra] shaharofir:
Yes,I've done it with success. Look for instruction in the attached file. Just make sure you are running latest firmware

I wish I could, but time doesn't permit. Also not worth to spare time to build for very few users (most having ultra)
[Samsung Galaxy S21 Ultra] macdanger:
Hi Dr.Ketan,

thanks for providing this ROM as well as Tweaks Pro. I installed R8 and it went smoothly. One question though:

I mainly installed it in the hope of having better multiuser support. I was able to activate multiuser with Tweaks Pro but there is no easy way to switch the user profile. Did I miss something or is there a tweak to show user switch in the QS panel?

thanks and cheers
[Samsung Galaxy S21 Ultra] dr.ketan:
If i remember correctly, user qs tiles natively removed since long. I may add custom tile to change user but again custom time won be available after changing user (only available in administrator)

Better change user from Settings - account & backup - users
[Samsung Galaxy S21 Ultra] macdanger:
Thanks a lot for responding this quick. A custom tile would be great but if this is only in the main (admin) account then it's only half the way...

Now I'm getting off topic but does anyone know another way (e.g. using tasker) to have a button/app/shortcut to switch users?
[Samsung Galaxy S21 Ultra] vlubosh:
So much stuff to rework for s21?
[Samsung Galaxy S21 Ultra] babyboy3265:
Can you describe your steps that worked?
[Samsung Galaxy S21 Ultra] shaharofir:
Exactly as written in the pdf:

1. Install AUG4

2. Reboot to TWRP

3. Install super as image and G998B_DrKetanROM_R*.zip as zip

4. Wipe Dalvik and cache

Hi, I got a G998N(Korean version) and tried to install the rom. Before odin falsh, all went fine. When flash BL,AP,CP through odin, it stucked at uh.bin. I think there is a minor difference between two versions of bootloaders. Any solution here?
[Samsung Galaxy S21 Ultra] dr.ketan:
You needs to flash bootloader and modem from own device with same base in case you want to try on other variant.
