Cannot install any apps after installing Xposed framework (-504 error in Google Play)

A few days ago I posted a question about not being able to install any Xposed modules here, so far no one answered: https://forum.xda-developers.com/xposed/xposed-framework-installed-running-t3567230
I thought this problem had something to do with the modules specifically, but it turns out that on my phone, for whatever reason, installing the framework subsequently prevents ALL apps from installing, even those from Google Play itself, displaying a "-504" error.
I see people have asked this question before, but are also not getting answers: https://forum.xda-developers.com/xposed/install-apps-installing-framework-t3430922
Please, if anyone has any idea of why this can be and how to fix it, let me know. Any help will be infinitely appreciated!

What phone and ROM are you using?
One thing you could try is to install systemless Xposed through Magisk. Then use MagiskHide to hide both root and Xposed from all Google apps and potential sources of conflict. If it's a software limitation/conflict, this may be a workaround.
Keep in mind that you will have to root your phone with Magisk rather than SuperSU or any other form of root.

Hey, thank you for your answer!
I am using a Sony Xperia M4 Aqua E2306, rom is 26.1.A.1.112 Latin America Generic. It is rooted and with TWRP installed accroding to this thread: https://forum.xda-developers.com/m4-aqua/general/root-e2306-m4-aqua-guide-t3270521
I also have a locked bootloader, and it cannot be unlocked, so unfortunately that shuts the door on most rooting options.
I never heard of Magisk before, but from what I'm seeing, it looks it TWRP is required to get root with Magisk, but some kind of root is already required on my phone in order to get TWRP. So I'm not sure how to go about this.

If your phone is already rooted, then you can download Magisk Manager application and have it installed it's necessary frameworks through the app itself. You won't be able to use Magisk's root, but you'll still be able to install systemless Xposed and hide it from other apps.
Edit: Ignore all of that actually, I just realized that magisk requires boot image modifications so you have to have an unlocked bootloader to use it.

Oh well, thanks anyway. I might try it anyways, maybe it will work, you never know. Don't have much to lose at this point

FIY Magisk cannot hide Xposed...

I also facing these problem on my rooted Asus zenfone 2 (ze550ml 2gb ram version, Stock ROM, bootloader unlocked) and Asus Zenpad C 7 (p01y, stock rom, bootloader unlocked). The xposed firmware (version 86) is successfully install but can't install any apps from play store and using apk...
I really hope that dev team can solve it.....
Sorry for any grammatical mistakes....

The only way is to flash the firmware

I'm getting the same problem on my LG G4 with v88.2 of Xposed :/

I don't Know if this is too late,but I also have this problem. But there is a work around, go into the xposed installer and turn the switch off so its disabled on the next boot. rebot the device and exposed and its modules are disabled, allowing you to install apps from play store and downloaded .apk files... it would still be nice to install applications while its still on.

I had this issue on my LGG3. This happens when you have Lucky Patcher enabled in your xposed modules. Disabling it (Lucky Patcher) should solve the problem.

LineageOS Help

Hi XDA!
I need some help with lineageos on here. I'm a pretty seasoned flashaholic and generally know what I'm doing however this is stumping me.
Anytime I install lineageos + magisk, I have no root. All flashing goes to plan, however when I open magisk manager I get one of 2 things:
Either, I'm rooted with magisk installed, or I'm not rooted with magisk installed.
It seems to depend on which root app gains root first - for example, if magisk says I'm rooted (e.g it'd the first app to gain root) then any other app I open afterwards will tell me I'm not rooted, including root checkers. If I open a root checker first, it will say I'm rooted but then magisk will say after that I'm not, but magisk is installed, and all root apps from then on will fail. I'm really not sure what the problem is, and I have done clean installs, dirty flashes etc. All I have enabled is magisk hide and its busybox toggle. I've tried turning off it's busybox but no luck.
It gets worse if I enable developer options, Even if I don't touch any root settings in there (I like to disable Bluetooth absolute volume). If I do this, I loose root completely, but it still says magisk is installed. I'm not using SuperSU as I want to pass safetynet, and there are no su files from lineageos in /system/bin or xbin.
Obviously doesn't happen with OOS and all works fine.
Firmware is correct for LOS etc
If anyone can help I would appreciate it

Bump anyone?

Do you have Magisk built-in busybox enabled? If so, try disabling it. From the Magisk release thread:
FAQ:
Q: I am losing root randomly!
A: In some custom roms (known: LineageOS), enabling the Magisk busybox will make root unstable
If you experience root loss issue, disable busybox in MagiskManager

Thanks for the answer, but you didn't read all i put. It happens with or without busybox enabled. It happens more when i have developer options enabled so i can disable absolute bluetooth volume.

Oh crap... I did miss that part... Sorry about that. Gonna blame a long week and tired eyes.
No idea then, other than it being a LineageOS issue (I really dislike that ROM).

Magisk Hide and Microsoft yammer/skype for business

i have galaxy s7 with superman rom 2.8 and rooted with magisk. I have a question in case you could help. I'm using version2.8 with magisk for root.
There are a couple of business apps like yammer and skype for bsns that I cannot use as they detect my phone is rooted and won't allow me due to root. Magisk hide doesn't seem to resolve the issue. Any other way I can hide root?

Take a look under "Hiding root from apps" in the troubleshooting guide. Might be some pointers in there that could help.

For Skype you can try this magisk module.
There is an issue with that module on magisk 18 though, root gets detected every so often and kills skype, it actually makes magisk fail safetynet. Toggling magisk hide off and back on in settings will temporarily fix it. Hopefully there's some kind of fix either from magisk or that module because it's severely annoying, but that's the only thing I've found that gets skype working with root.
(edit: dammit, didn't mean to resurrect an almost year old thread, I saw January and a 9 and I got confused )

Apps refuse to start because phone being rooted but it isn't!

At least 2 of my Apps refuse to start. One is my banking app and they do not offer any other way of interaction.
The problem is that the phone in fact is not rooted! It's just "OEM unlocked" to be prepared for root (which I need for E.g. titanium backup, but only maybe once a month).
Please give me a way out of this vicious circle!
I cannot remove the OEM unlock because it requires full wipe every time. Or is there a way?
Or what can I possibly tell the App Provider to improved their Code so that Oneplus phone state is being recognized (more) correctly?
Any help would be greatly appreciated.

Use Magisk I guess? Use it to hide root from that app.

In fact I already flashed an official image and still (with no zip installed via TWRP) I'm getting refusals from these apps.
So for sure some apps decide from something else then simply an installed "root" manager or the installed "su" binaries.
What else could they decide from? "OEM unlock" was my first guess (and it would also be the worst, because as far as I know it can't be "hidden" temporarily, or can it?), but maybe there are other settings. Does anybody know more?

You need to do some reading about Safetynet. If you're OEM unlocked you fail Verified Boot checks. Most custom Kernels include a bypass for this. Magisk alone should also work. I think you missed one important step:
Open Play Store Settings. Scroll down. It says 'Uncertified' at the bottom, right? Now install and set up Magisk. Go to system App Settings and clear Data and Cache for Play Store. Return to the Play Store Settings and scroll down. Now it should say 'Certified'. It might not be immediate, but it will happen. Now your Banking Apps work.
If you don't want, or have no luck with Magisk, simply flash a Custom Kernel that bypasses Verified Boot, and works with OOS.
Simple.

Thank you. That was for sure a major part of the overall issue. Unfortunately it didn't yet fix it. I'm now certified in play store and magisk succeeds with both safety net checks (which however it also did before). And root is disabled in magisk. dm-verity does not show the warning during Boot and the Check itself should be disabled (I followed the recommendation in another Thread to Patch the Boot Image).
Anything else you can imagine?

Link to other Thread?
I don't know Magisk but are you hiding Root from your Banking App? Have you cleared Data and Cache for the Banking App since getting Certified?

First my phone did not Boot any more after installing superSU. Fixed that by patching Boot.img (to disable dm-verity) according to this thread: https://forum.xda-developers.com/oneplus-3t/how-to/disable-dm-verity-force-encryption-op3t-t3688748
Now data and cache of all (now) 3 affected Apps has been cleared and Magisk is configured to be hidden for them, but still no change.
However, in Magisk there is the "extended" option "AVB 2.0/keep dm-verity", which is unticked. I'm not sure, should I try to set it?
Any other idea?

Nope. If Play Store says Certified you should be good to go. I can only imagine it's a Magisk issue. Post screenshots of your config and let the Magisk experts pick through them. Maybe there's something not set up correctly.

Hide Magisk Manager. I had to do that to get my banking app to work.
Edit: you may need to reboot after hiding Magisk Manager and clear you banking app's data before it works.

Thank you, indeed that WORKED! Well, at least for 2 out of 3 Apps. I think I can tell which one: "HVB banking". Maybe could somebody cross-check this one on his/her phone?

After firmware update to OOS 5.0.5 I now have the problem that my PlayStore can no longer be convinced in any way to show that it's certified. But interestingly my banking Apps work (currently really no root app installed). I even waited for one day because earlier in this thread somebody mentioned that it might take awhile. Is there anything special I need to care about under the new OS version?

Did you reflash custom kernel after update?

I'm not using any. What I did right after the update is to disable dm-verity (with a patched boot.img), like I did last time. But magisk is not yet re-installed because I wanted to see at least once the HypoVereinsbank App working, which it in fact does (different to last time when the phone was not rooted as well, and the store not certified!).

That's why... You can't pass the ctsProfile check if your bootloader is unlocked, and if you can't pass the ctsProfile check the Play Store won't be certified. You need Magisk for that...

Now I'm getting confused. The initial mail of this thread explains the situation as it was when I opened this thread:
--> Original ROM, no root, and banking apps didn't work <--
The advice to clear data of the PlayStore immediately brought the PlayStore back to "certified".
This is clearly in contrast to what you're saying now.
I can imagine only one reason: Maybe the older PlayStore had a bug and therefore was able to "certify" even with unlocked bootloader?
Sidenote: My main intention to do the firmware upgrade was that the "safety net checks" in Magisk suddenly stopped working one day (with the error message "invalid response", most probably you know what I'm talking about, I've read some comments from you on this issue). Therefore it's maybe really not too unlikely that Google has changed something very basic. Could you please confirm?
Edit: Now magisk is back, version 16.7, and in fact PlayStore is back to "certified" AND now even the HypoVereinsbank App works. Just one thing remains: magisk safety net check still says "invalid response" (after it downloaded some "FOSS" code, which it didn't do last time, when it was still working).

Sorry, now comes a probably often asked question: do I need the safetynet check option in magisk for something real? Or do the alternative apps fulfill all possible needs? What are these needs? Isn't that exactly what the PlayStore does to determine "certified"?

After quite some months of absolutely no "root" problems with any of my apps, since today o2banking again doesn't work.
I tried to update Magisk, but after update of the Magisk manager app to v7.1.1(203) it reports that Magisk is not installed at all, and any update of Magisk itself resulted in just the same. So I reverted back to v6.1.0(165) and everything seems to be okay, except that o2banking doesn't work. SafetyNet is clean, Magisk is hidden for o2banking and Magisk manager is repacked.
Does anybody know what the problem might be? Especially with that new version of the manager app, but also with Magisk v19.0 which cannot be installed from v6.1.0 (max. is v18.1). Any ideas welcome! I'm now on OOS 5.0.8 by the way.
SOLVED it myself: As mentioned somewhere in the update FAQ of Magisk there was a bug in manager v6.1.0 that causes the updated v7.1.1 to co-exist with the old version if the old version has been re-packed. If anybody encounters the same problem, the solution is at the bottom of this page: https://www.didgeridoohan.com/magisk/ManagerIssues.
o2banking will then still not work. Update to v19.0 is mandatory. But that is no problem then any more...

probably your banking app identified oxygen os as custom rom and have root. 1 out of 3 banking app in my phone doesn't work with lineageos even though i already hide magisk, but when running oxygen os with magisk hide, and also hide magisk manager (turn it on in magisk manager setting) all 3 banking app work just fine. maybe try sending a message to bank app developer to add oxygen os as exception.

Did you notice my edit? It was a problem with magisk manager update and magisk main version. Now everything is back up and running.

Note9 Randomly Reboots and Partly Goes Back to a Previous State

Hey guys!
I recently flashed my Galaxy Note9 (SM-N960F, One UI 2.5) with TWRP and Magisk, all being the latest version. However my phone would just reboot randomly and I could barely find a pattern. I could only infer that the reboot is system level since most of the time I was launching a system-level app like Bixby, Torch, or just simply swipe down the notification panel. If related, 19:30 seems to be the time my phone would definitely reboot recently.
By ''partly goes back to a previous state' I mean some of my apps would be replaced to their factory version. Like I used YouTube Vanced, and after this one reboot it went back to its factory version. And Gboard was exiled of all its permissions once. My Edge Panel was reset after one boot. Some of the adb tweaks were reset.
I'm half sure this is a kernel problem, and the only modifications I did to my kernel were Magisk and Universal DM-Verity. I don't know if it's a DM-Verity problem.
I tried to disable my root permission for apps but it didn't help. Also Googled how to catch system logs but none of these worked.
If you're experiencing the same problem or have an idea of how to solve this issue please feel free to leave a comment!

Happened to me as well few months ago.
I suspect it is related to safetynetfix or hideprop. I used safetynetfix for samsung, and update latest hideprop, now i never experienced the random reboot.

Thanks a lot! My phone now boots normaly and it's a Success on SafetyNet. Hope no more random reboots afterwards.
I'm particularly curious what variant of DM-Verity did you use? I googled for DM-Verity for Samsung this morning and did get a Samsung-only patch. I'm not sure if DM-Verity patch could contribute to these reboots.
