You literally said it yourself, "old", so have a look at those old solutions you speak of, see how old are they, look at external links, description and whatsoever...

I'll give you time to think why it's not updated, why it might have been archived and why KnoxPatch by @BlackMesa123 is the right way and hustle free for knox tripped devices...

Moreover, this is a common information on every Samsung Thread on Root, once knox tripped, you can never untrip it, you must hide the Knox state from all Sammy apps and if you don't care then uproot and use it without Sammy apps...

Here is an alternative solution, flash a custom ROM that is knox patched, it might not feel Sammy but it should work and unrooted...

Other than, root it again and apply knox patcher or buy a new phone if you no longer want to root again...

Finally, as a patcher myself for shm, the process of patching is overwhelming, and I patched knox in shm (with the help of @BlackMesa123) even though it was not needed since knox patcher will be installed by default on rooted devices but I did it anyway, moreover, let me shed some light on something important, apps with cloud services are blocked very fast due to signature verification on server side, this is unpatchable, the app loses cloud capabilities and online services, so how to keep the signature intact? Patch knox, when apps request for knox state, they recieve flag untripped, and if the server checks for app request signature, it's still valid...

This isn't a criticism, you asked a question and we gave you an answer...
[Samsung Galaxy S23 Ultra] Dante63:
As I recall knox has poor implementation in older device, that knox doesn't trigger but if it does, perhaps removing knox app would fix it... but make a backup...

Hello everyone, my S23u device crashes when deleting a protected folder. Has anyone noticed? Are there any solutions to this problem?
[Samsung Galaxy S23 Ultra] waterpolo:
Did you use the latest GitHub version 0.7.0?
[Samsung Galaxy S23 Ultra] kentabdulla:
yes, I'm using the latest version from github
[Samsung Galaxy S23 Ultra] kentabdulla:
I have a ROM installed from Dr. Ketan. When I install lsposed, it crashes.
[Samsung Galaxy S23 Ultra] Rawdog.dll:
Thanks!

S10 - One UI 2.1
[Samsung Galaxy S23 Ultra] waterpolo:
What does this means?
[Samsung Galaxy S23 Ultra] Rawdog.dll:
Hello friend. This means that it worked on my config quoted above.
[Samsung Galaxy S23 Ultra] MoveToZero:
Hello Salvo/BlackMesa

I tried both the app and module today, since I had issues running Samsung Health and Samsung Health Monitor on a rooted S21 due to triggered Knox.

UI 5.0, Magisk 25.2 (hidden), apps hidden with latest Shamiko, latest LSposed and latest kdrag0n SafetyNet Fix.

Samsung Health works without issues now, but Health Monitor still cannot connect to my GW4. Otherwise the watch connects and I can use all features except the one dependant od SHM (ECG & Blood pressure). I also tried a modified app from Dante63 on the GW4 forum, with same results.

I pass all SafetyNet checks and Momo shows only "bootloader unlocked" and "Data not encrypted, mount parameters are modified".

Do you have any Idea what's going on or is SHM still supposed to be broken ?

Thanks!
[Samsung Galaxy S23 Ultra] BlackMesa123:
Have you installed the KnoxPatch Enhancer Magisk module?
[Samsung Galaxy S23 Ultra] MoveToZero:
Yes, I forgot to mention that. Also, I have TWRP instead of the stock recovery.
[Samsung Galaxy S23 Ultra] BlackMesa123:
Have you gived a try to the BluetoothLibraryPatcher Magisk module? Just to make sure it’s something that can be solved easily and doesn’t needs debugging
[Samsung Galaxy S23 Ultra] Has_anDroid:
Thank you working all maybe possible samsung pass next time ?
[Samsung Galaxy S23 Ultra] Has_anDroid:
Oh now s health not work
[Samsung Galaxy S23 Ultra] BlackMesa123:
Still works fine here. Make sure the app is selected in the module settings
[Samsung Galaxy S23 Ultra] BlackMesa123:
Even without logs I'm pretty sure the reason is because the TA checks for the device's warranty bit before handling the requests from AuthFw, so there's no way to bypass this check.
[Samsung Galaxy S23 Ultra] zzattack:
Used knoxpatch to regain the ability to create a work profile. Worked perfectly. Thanks a lot for your efforts.
[Samsung Galaxy S23 Ultra] MoveToZero:
I did, but it makes no difference. Now that I think....My phone was bought in Italy (Unbranded). I don't know the original csc, but the model number ends in EUE, so it was one of the italian ones. I flashed the EUX software though, and now I have a German SIM. Maybe everything is conflicting...

Edit:

Clean flashed new firmware (EUX was also stock), Twrp & vbmeta, rooted with Magisk, went through all the modules mentioned above again. And still SHM doesn't wotk due to (I presume) tripped Knox or encryption errors.

---> E/S HealthMonitor - WsmController: WsmSession.connect(). fail : ERR_INTEGRITY
[Samsung Galaxy S23 Ultra] BlackMesa123:
WSM should be bypassable by installing the KnoxPatch Enhancer module, since it's the same system service used in the Galaxy Wearable apps.
[Samsung Galaxy S23 Ultra] MoveToZero:
All other apps mentioned in the first post work with your module & enhancer (I see the enhancer being active in KnoxPatch settings) , which is bloody awesome. It's just SHM that is acting up.

The only way I can use it is if I clean flash the same firmware and lock BL. Once BL is unlocked, there is no way to connect SHM to a GW4.
[Samsung Galaxy S23 Ultra] EtherealRemnant:
Have you tried the modded SHM in the GW4 subforum? It's meant to work with non-Samsung devices that normally can't run it so I would imagine it would work on a Knox tripped Sammy too.

https://xdaforums.com/t/restriction...triction-removed-24th-jan-2023.4322527/unread
[Samsung Galaxy S23 Ultra] MoveToZero:
Yes, tried and doesn't work. There have been only like 3 or 4 users in that thread reporting on the knox/unlocked BL issue on newer Samsungs and galaxy watches. There is a warning on the first page acknowledging the issue, which is supposedly related to encryption. But afaik, there was no solution for rooted s21/s22 series.
[Samsung Galaxy S23 Ultra] EtherealRemnant:
That sucks. It was worth a shot.
[Samsung Galaxy S23 Ultra] BlackMesa123:
I have to ask you to send over some system logs of the issue so I can see what’s going on.
[Samsung Galaxy S23 Ultra] MoveToZero:
I hope you can make anything out of it, to me it's rocket science. I tried a few connections with the stock SHM and modded SHM while logging.
[Samsung Galaxy S23 Ultra] BlackMesa123:
It looks like you haven't installed the Samsung Accessory Service app (apkmirror), which is strange since it should be installed as a system app. Did you by any chance debloated your device?
[Samsung Galaxy S23 Ultra] MoveToZero:
No deabloating yet. Apart from TWRP and Magisk, LSPosed, and all the modules, it is a stock rom. I installed the app and still nothing. Below you have new logs after Samsung Accessory Service was installed.

It's really funny to me how they put such effort in preventing blood pressure readings on a watch, when banking apps checks can be bypassed.
[Samsung Galaxy S23 Ultra] fede2782:
I would like to root my device and install this module. Does this make the EGC and all Galaxy Watch-related features working? I mean Samsung Health Monitor correctly syncs with watch and with Samsung Health app
[Samsung Galaxy S23 Ultra] BlackMesa123:
An user (@MoveToZero) is currently having issues on its end. I suggest you to go ahead, root and install this module, and if you can please report everything works fine in your end.
[Samsung Galaxy S23 Ultra] MoveToZero:
OK, so here's that. I was fed up and flashed again to stock and then installed TWRP, rooted, and flashed all modules already mentioned.

And damn, it works !

I did nothing different than in previous flashes, but it just works now. SHM recognized the watch on first try and I can use BP and ECG. I still get Accessory Service and some other SHM related errors, but ERR_INTEGRITY is gone an everything on the front end seems to work fine.

Thank you immensely for all the help!
[Samsung Galaxy S23 Ultra] fede2782:
Do you have disabled encryption?
[Samsung Galaxy S23 Ultra] BlackMesa123:
I completely forgot to tell you to try deleting the apps data and reinstalling them, an user on GitHub reported this did it for him.
[Samsung Galaxy S23 Ultra] BlackMesa123:
I doubt the WSM integrity check has something to do with encryption.
[Samsung Galaxy S23 Ultra] fede2782:
Ok, if I don't have to disable unencryption I'll try to root my device

[Samsung Galaxy S23 Ultra] BlackMesa123:
Try flashing Shamiko Magisk module, also make sure SafetyNet attestation passes successfully.
[Samsung Galaxy S23 Ultra] fede2782:

[Samsung Galaxy S23 Ultra] BlackMesa123:

switched from Note20 Ultra
[Samsung Galaxy S23 Ultra] BlackMesa123:
Use YASNAC to verify your SafetyNet attestation status
[Samsung Galaxy S23 Ultra] BlackMesa123:
Check it out, it should be enough to spoof Zygisk/LSPosed presence to other apps.
[Samsung Galaxy S23 Ultra] Marianxs:
Now i tryed

i installed Shamiko v0.6-126

uncheck "Enforce DenyList" and reboot

Safetynet passed - play store is certified

Clear caches - reboot - nothing

Uninstall Shamiko, reboot

clear cache play store, services, wallet - reboot

Looks like there's something wrong with your efs partition since keymaster can't find your device's attestation keys. Do you have a backup of your efs partition by any chance?

No i dont, i patched my imei using Chimera tool.

Before that i was on android 11 and securefolder was working fine using smali patcher.
[Samsung Galaxy S23 Ultra] BlackMesa123:

Hello, I have a Galaxy S20 with android 10 installed knox 0x1. I want to upgrade this device to adroid 13, but my galaxy watch active 2 does not work, can I solve the pairing problem with this program?
[Samsung Galaxy S23 Ultra] BlackMesa123:
Unfortunately I can confirm the issue is in your device, without the attestation keys in the efs partition you can’t use those features that requires Knox keystore such as Secure Folder or Secure Wi-fi. The only way to fix it is by getting back your DAKs in the efs partition, and I onestly don’t know another way than restoring the original efs partition from a backup
[Samsung Galaxy S23 Ultra] BlackMesa123:
Make sure to install both base module and Enhancer and you should be fine.

[Samsung Galaxy S23 Ultra] Garock:
is it possible to use Samsung Flow while the phone is locked using this tool?

for a few versions back, Samsung Flow no longer allows unlocking the phone using PC. so if the phone is locked, you need to unlock the device manually before using the app which completely defeat its purpose (similar behavior to latest versions of Phone Link)

see https://us.community.samsung.com/t5/Galaxy-Note-Phones/samsung-flow-4-9-04-4/td-p/2499621 for some details. and in the latest version, you're left with an error message "To use Samsung Flow, verify your identity using the authentication methods you've turned on. Make sure your phone or tablet has Samsung Flow open and is connected to the same network."

or is this completely outside of the scope of the tool?
[Samsung Galaxy S23 Ultra] BlackMesa123:
Currently there's no plan on extending the module's scope except for bypassing the "security policy" checks of Samsung apps/features.
[Samsung Galaxy S23 Ultra] BlackMesa123:

Is that possibly related to the model? In fact, except for this patch, nothing has been changed. Then you can use the security folder!
[Samsung Galaxy S23 Ultra] BlackMesa123:
I tested the module on my A52s with OUI 3.1 and it won’t work there either, would be nice to have some debug logs of the creation of the Secure Folder in your end to see how the system behaves
[Samsung Galaxy S23 Ultra] Bkblues:
What do I need to do?
[Samsung Galaxy S23 Ultra] BlackMesa123:
Create a system log using logcat while creating Secure Folder (creating, not unlocking the existing one)

[Samsung Galaxy S23 Ultra] gorthon:
First of all, a big Thank you, this is a pretty cool module! I get work profile working, and even "Software Update" is now displayed in the setting (but registration on server fails, of course). Samsung Health und Health Monitor are working as well. I had to watch out to remove them from Magsik Deny list, and then they worked.

I am only wondering about two things:

1) Where can I see that the Enhancer is working? In Magisk the Enhancer 0.2 is activated, but in LSPosed the KnowPatch entry in the modules list does not show a green "Enhanced" text, see attached screenshot. The initial post does not specify where this is supposed to be shown, so I assume the modules list in LSposed, right?

2) After every boot I get three times a grey screen with the message "Access denied - Unauthorized changes have been made to your phone...", see attached screenshot. By looking at the screenshot name, I could find out that this is from "Samsung Wallet Digital Key". This also appears occasionally while using the phone. Is there any way to get rid of these?
[Samsung Galaxy S23 Ultra] dr.ketan:
1. Execute from terminal

adb shell su
adb shell pm hide com.samsung.android.dkey

Or

2.Settings -apps - show system app - search digital key - open it and disable "Appears on Top" permission

Thank you, that works (and Freezing in Titanium Backup works as well, as I found out).

[Samsung Galaxy S23 Ultra] BlackMesa123:
1) You have to open the module info page by either clicking the bottom right action button in the KnoxPatch module page, or the “KnoxPatch Settings” button in the application info in System Settings.

2) There’s currently an open issue in GitHub (#5) regarding this app, I don’t have a way to test the patches myself because my device doesn’t have this app, so I need someone willing to test.

Refer to the supported Android versions/supported apps lists in OP, your device is supported.
