A71 Data & Root Issues - Samsung Galaxy A71 Questions & Answers

Hello,
The last couple of months and completely out of no where my 4g data randomly stops working. The status bar icon shows that it's stuck on upload and won't download any data. The only way I've found to fix it outside of restarting the phone is to change the cell band type from auto to wcdma then back.
Anyone have any ideas on how to fix this?
Second issue is with Magisk and I know this is for Samsung but I figure why not ask anyway. As of yesterday after a reboot I lost root. Magisk apps shows I need to install magisk and install the app even though I'm in the app. Also a bunch of my apps are acting like I've never uzed them before and they need to be setup again. I haven't installed any updates so I'm not sure what caused it.
I've tried completely uninstalling Magisk and reinstall and that didn't do anything. The install went through fine but after launching the app it still says no root.
Any ideas?
Thanks

Hi, I think it has been updated and Magisk is useless due to new layers of security. I guess we'll wait until a new rom is made for the new update, including stock. I don't know if Magisk can release a new version and overcome this.
Thanks.

Reflashing the custom firmware then also Reflashing Magisk did get it working for me again.
I've since updated to the newest firmware, flashed OneOS and Magisk and it's been working fine until a little while ago when Magisk randomly shows as not installed again after a reboot.
I take it no one else has had this issue still?
Thanks

[Q] Note 4 Lag and Fingerprint not working - tried everything

Hi everyone, OK I've tried everything in other threads, here's the situation:
Note 4 Sprint
cf-auto-root worked fine, everything working well for a week (stock recovery, stock ROM, just root). Then installed xposed (accidentally used the experimental 2.7 version) and RootCloak module. This threw me into a boot loop.
I recovered from it by redoing cf-auto-root/odin. That got me out of the loop, but-
Ever since then:
- Phone lags for a few seconds every few seconds - making it hard to even type in a phone number, let alone watch a video,
- Fingerprint doesn't work - when launching the menu from settings I get an error that it's unavailable.
I've tried everything in the other threads:
- build.prop change (disabling securestorage)
- successfully installed 2.6 xposed and tried:
- wanam xposed to disable securestorage
- and the xsecurestorage module
- flashed stock rom from sammobile with odin
- even tried disabling selinux with wanam
No matter what, these same issues. I haven't tried anything other than the stock rom. Any ideas at all? Is there a different ROM out there I should try? Does that even have a chance of working?
I'm not sure I understand why flashing stock didn't fix it - even though it caused me to lose root...
Right now I have TWRP with root and stock ROM.
Any ideas or suggestions really appreciated.. I'm out of ideas. Thanks
I have the Same Problem
I had the same problem, haven't bothered installing it again since, don't suppose anyone has heard from the developers?
Hope maybe the devs can shed some light here. Is there anything else I can do? Flashing stock didn't even help. What's left?
So after not touching anything for about a week - things started running smoothly. Very odd - didn't change anything. Xposed was uninstalled for that time.
But, after SuperSU updated (and updated the binary/rebooted), the lag came back. So, this is telling me this may be related to root/SuperSU instead.

Magisk 11.1 and ViperOne M9 ROM issues - lost root

Hi guys - I'm having trouble with the latest version of Magisk...
My ROM - ViperOne M9 (for HTC One M9) - comes packaged with Magisk 10.6 and phh's Superuser, and it seems to work ok out of the box. However, I can't get it to pass SafetyNet checks with HideMagisk enabled, which is an annoyance as I can't use certain apps (no, NOT Pokemon GO FYI ). The Magisk Manager was advising to update itself, which I thought might help - so I did. After a reboot I have now lost root on my device, and cannot get it back.
A knock-on effect seems to have taken out phh's Superuser too, as it now complains of out-of-date binaries when the phone boots up, and I'm not getting any permission requests any more. I tried revoking Magisk's permissions, but it never tried requesting them again.
I flashed the phone using the latest TWRP, and my firmware and bootloaders are up to date also.
Not sure whats going on here - any ideas?
I could re-flash the phone, as I did a complete wipe earlier today to update ViperOne to the latest version (version 6.00) - so it's not a major headache, and should give me root back. But then I'm back to a broken hide-root/SN bypass. Again, this isnt a major problem since I'm used to not using those apps - but it would be nice to have.
Cheers.
Guys, managed to resolve my problem.
I downloaded the latest ZIP for Magisk 11.6 and phh Superuser, and flashed using TWRP. Rebooted, and all working!!
Also FWIW, I solved the problem with SN failing.... well I installed Magisk 11.6 and the work you guys did obviously did it for me, so thank you!

Help required. Magisk keeps uninstalling and losing root

Not sure what's going on here. I rooted exactly per the guide last week but I have noticed sometimes when I go to use Android pay it won't work. When I go to magisk manager it's not installed. I have flashed it again several times but it will randomly uninstall.
I tried the patch that had something to do with file access but it's still the same.
Is there a fix for this?
Thanks.
Does no-one have an answer to this?
If Magisk just isn't going to work I would rather know about it rather than it just not being installed randomly.
Thanks!
I actually having a similar problem...
Are you in the beta channel? Might want to try switching back to stable
I've just switched back now. Let's see how it goes!

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.

help for rooted note 8

Hi guys. I need some help for my rooted galaxy note 8. I had rooted my phone a long ago and all was working good. All apps including banking apps were working fine with magisk hide. But few days ago i wanted to update my phone so i flashed stock rom with odin and updated my device. Earlier my bootloader version was 6 and now its updated to version 8. Then after updating i flashed latest twrp and rooted with magisk. I flashed magisk version 20.1 and magisk manager version was 7.4.0 . Then magisk update was available so i updated to magisk version 20.2 and magisk manager to version 7.5.0 . Now the problem starts. I am facing 3 issues.
1- my phone starts freezing and then reboots randomly. It happens quite frequently atleast 2-3 times in a day. Every time i clear cache partition from twrp but problem persists. I had checked ram also but ram useage is also fine. Please help me with this issue.
2- while searching for the solution of above problem i read somewhere that it might be because of safety net check. Earlier safetynet check was pass but now safety net check was fail. I flashed bypass safety net mod. But when my phone reboot a warning appears that your device has some internal problem. Contact the manufacturer. I pressed ok and phone starts. It seems to work normal but then i realised my device was not connecting to any wifi network. When i click on available wifi nothing happened. So i uninstalled the safety net bypass mod and then wifi start working again.
3- now final thing i want to know. If the above problem did not solve then i have to unroot my phone which i dont want. But if i had to then i dont want to flash stock rom. I want to unroot from magisk app itself. I had edited build.prop file for using samsung health app. So now if i unroot from magisk app will the changes made by me in build.prop file remain or it will revert back. Also will banking apps work or not....
I know its very lengthy post but please help
Wow...
70 views no comment..... it seems all the developers and tech people are enjoying winter break
Try going back to previous version of Magisk. I have Snapdragon N8 so I have supersu. But I did update my A20g with newest Magisk and had an issue. I know you have N8 but was just saying maybe could be new Magisk.
