[Q] Systemless Root causing boot loop - T-Mobile N900T - Galaxy Note 3 Q&A, Help & Troubleshooting

Hey everyone.
Like many Android users, I've been struggling to find a ROM and systemless root combo that passes SafetyNet (ever since Pokemon GO 0.37 update). I eventually found a ROM that can be unrooted cleanly (AryaMod S7 Edge port), and managed to get SafetyNet working via Phh's Superuser (first with Magisk + r251, now using hidesu version r266).
However, I soon ran into a problem: The systemless root appears to be causing my phone to bootloop. There seems to be a gradual degradation of the bootimage somehow caused by systemless roots; my phone would work fine for a while, then gradually apps would force close or the phone would freeze. If I try to reboot, the phone then gets stuck in a boot loop (which occurs before the ROM even starts loading). I am very sure this is caused by an error in the bootloader because this bootloop behavior persists through nandroid restore or clean ROM installations. The only way to fix it is to flash the stock bootloader via ODIN.
I noticed a few users in the dev threads of ROM's I've tried reporting the same issue, but in the dev thread for Phh's Superuser there seems to be a lack of mention of this issue (likely model-specific, as I am using Phh's Superuser on my wife's Note 4 and her phone isn't bootlooping). Just wondering if anyone has experienced the same problem and found a solution?

I also have an N900T, and magisk v7 + phh is working fine for me if I don't install any extra systemless modules. When I installed the better battery stats module, I started getting bootloops, so there are definitely some issues with it.
Magisk is still being worked on, so it's probably only at alpha or beta status right now. Hopefully it will get more stable in the future.
btw.. I'm running the latest stock Samsung 5.0 rom (N900TUVSFPH3), which has the latest bootloader, since it seems the most stable to me.

Magisk 12.0 update douched my phone

So I just updated Magisk from v11 to v12 and my phone is totally douched up. After rebooting there's an "Unable to use fingerprints" message at the bottom of the screen, the touch screen is janky and my unlock pattern no longer works. The screen goes to sleep randomly too and then comes on without being touched. On the off occasson that the unlock pattern DOES work, the screen loads with no icons, just the page dots and status bar with my wallpaper and nav buttons. Uninstalled Magisk and got the same. Rebooted after uninstall, same thing. I guess I'll be reflashing the ROM, but this is a huge pain in the ass. :/
This isn't a question--more of an answer. DO NOT UPDATE to v12. If you did and have trouble, downgrade to 11.x.
I can second this. Updated to 12.0 and my phone started rebooting randomly and fingerprints started not working. Thought it was something with the rom so clean flashed it again, all was fine till I updated Magisk again. Downgraded to 11.6 and so far no more reboots and fingerprint works.
that's odd. it is working great for me. (currently using Weta 4.9.2 and Tilde's latest kernel + latest magisk manager and magisk 12.0 zip flashed)
Def breaks the systemui and causes the device to repeatedly crash on the ls997.
Was how it acted on pre 11.0 builds for us on v20.
Im testing with the dev on magisk now.
Updated to the latest, no issues here on RR with original kernel.

yeah aosp versus stock lg os act differently
i believe last time ls997 was the only one really having issues, but its breaking ui on the ls997
don't do it
I updated also, put phone in a never-ending 30 seconds to reboot. Had to restore.

H918 WETA ROM 4.9.4 + Magisk 12.0 bootlooping

Hello there, I've been using the V20(H918) for a little while now and was running WETA Rom 4.8.5 with Magisk 11.0. When Magisk 12.0 released after rebooting and being on for a minute or 2 my phone would suddenly go back to the T-mo splash screen as if it were soft rebooting and then would repeat this process. I thought it might have been a download or flash issue so I tried wiping and doing a fresh install but if I ever restarted the device the same issue would appear. I've tried selecting or deselecting a majority of the options in the aroma installer for WETA but nothing seems to work. The rom seems to work fine with SuperSU installed so I'm thinking it might be something about the way my phone is set up but I haven't been able to pinpoint exactly what it is and I really would like to use Magisk for the hide feature. Based on the thread it doesn't seem like there should be any issues and I'm unable to ask my question directly in the thread. I'm not very experienced with these kinds of things so I'm sorry if I'm not being specific enough or if the solution is obvious. Thanks for anyone's help and time with this issue!

Im currently running weta rom with magisk 12.0 on my h918. However there are 2 possible differences between yours and mine. 1) you are not in the latest version of weta rom 4.9.4. 2) you are probably flashing the stock kernel that comes in the weta aroma installer. Try with konvergent or another kernel other than the one from weta rom. (as soon as i flashed the weta kernel my phone was experiencing the dame thing yours did , then after i flashed konvergent back it came back to normal)

Did what you said and everything seems to be running smoothly, thanks very much for your help! Hoping a more updated kernel that doesn't force SuperSU and works with magisk comes out soon!

System Crashing

Over the last few days I've been having seemingly random instances where the system slows right down, becomes almost completely unresponsive, the home screen goes blank and sometimes only half the screen displays. I then have to long press to power off, but instead of shutting down the phone reboots, then everything is fine again. Usually this has been happening once every few hours, and when left overnight the display doesn't even turn on prior to rebooting (I can use fingerprint sensor and feel it vibrate to unlock though). A few times I have seen the error message saying 'System UI has stopped' but most times I reboot before seeing that.
I was running stock 8.0 unlocked and rooted with TWRP 3.1.1.0 and Magisk 14, and also using the pixel launcher installed as a system app, with no issues previously. I can't remember exactly now, but I am pretty sure I had this occur while on 8.0 prior to updating to 8.1 (possibly following an update to Magisk 15), but mostly it has been happening post-update to 8.1. I followed the stickied guide using step 9 first, and after that was getting very frequent instances. Then realized I was using an old 8.0 pixel launcher app so thought that might be the problem, so re-flashed everything, updated to TWRP 3.2.1.0, re-rooted and installed pixel launcher via the linked post below. Was then stable for almost 24hrs before having the issue re-occur, but with longer gaps between successive instances. Yesterday I re-flashed using the flash-all script (8.1) to try to clean out any gremlins - all went smooth, then re-flashed latest TWRP/Magisk and installed pixel launcher. Seemed fine for an hour or so...

Not sure what is going on, I don't think its the zip file, since I checked the hash prior to doing the very first update. Could be the launcher I guess, but wasn't having any issue before so don't see why that would be a problem. Only root apps I'm using are root explorer, naptime and f.lux. Naptime I haven't installed yet on this go around, and f.lux I uninstalled this morning to see if it makes the problem go away. I tried searching around and saw similar issues reported for people using substratum/themes, but I have never used anything like that.
I have a log but can't link it yet...?

Try using supersu again or maybe downgrade magisk. Mine for some reason after going back to supersu randoom reboot stopped. This even after ive downgraded to 8.0 thinking 8.1 was the reason though it was running fine before.

Thanks will give it a shot and report back. Like I said I think the instability coincided with an upgrade from Magisk 14.0 to 15.0 which happened right before I went to 8.1, so going back to 14.0 might be the first step for me.
Were yours just random reboot or also the system glitching/freezing?

Well... flashed the Magisk uninstaller from 15.1 and re-flashed 14.0 and no system crashes yet.
However now I can't enable assistant vice activation. Possibly a separate issue I suppose, but it was working before.
Edit: Uninstalled Google app updates and reapplied from play store and now working.
So just as a follow up I've been running fine on Magisk 14 without issue for some time now. Have not tried the recent 15.2 release.
However f.lux is not behaving normally and for some reason is acting almost like a yellow filter. I found the thread below which seems to indicate some issue between f.lux / Android 8.1 / Magisk.
https://forum.justgetflux.com/topic/4667/f-lux-not-compatible-with-android-oreo-8-1/7
I have been having this exact problem on my Nexus 6P. Glad to know that I'm not going crazy. The switchover point for me was exactly from Magisk 14.5 to 14.6. 14.5 works fine for me with no issues. 14.6 and onwards (including 15.2) has exhibited this behavior very regularly.
One thing that I just tried that might have "fixed" it is I recently was in 15.2 beta (installed via TWRP) and it was having the problem. I was on the beta in order to capture some of its verbose logs. At one point, I wanted to just try a different installation method so I made sure to check the two options in the MagiskManager ("forced encryption" and "dm-verity") so that they are on and then reinstalled Magisk 15.2 directly from MM. After doing that, I haven't seen the issue crop up, so maybe installing from MM to make sure that it uses those options on install is the way to address this? I'll update if I see any more issues.
Thanks for the replies here and in the Magisk beta thread.
After installing with your described method/settings I reinstalled f.lux, and had a couple of glitch/reboots. I then uninstalled f.lux and I'm now over 24hrs without going into the glitched state. So it seems maybe this a compound issue. Can you confirm whether you had this or another similar app installed? I've seen other reports of this kind of behavior when using substratum.

Hey just a heads up - I am now on opm3 (Jan) and 15.2 beta with the just preserve encryption checked and no glitches yet after ~15hrs. Will be installing f.lux soon to see if it triggers.
Installed f.lux and maybe an hour later started glitching. Uninstalled and had to reboot to clear things up, and now haven't had a glitch since. So definitely the source of the issue, but it's a compound thing since it only started happening since Magisk 14.6 onward. However, there are other reports saying f.lux hasn't been behaving properly on both 8.0 and 8.1, so likely not the fault of Magisk at all.
Hey, I was linked to this thread from Magisk thread, I had the same issue on my Nexus 5X with Magisk 14.6+, so I uninstalled f.lux and issue is gone as you said. Now I'm testing CF.lumen on Magisk 15.3 and it is w/o any issue so far.

(Magisk) Phone randomly stuck on boot issue

Hello guys! I know it's a common issue, but when I reboot my phone there's roughly a 50% chance it gets stuck on the boot screen and I have to reboot. It's surely caused by Magisk, but has someone found a fix already?
The bricks got more frequent and really annoying when I began to install some modules (Xposed, Viper ecc.). Sometimes it takes even 2-3 reboots to start my phone properly, and sometimes it boots without recognizing my sim card.
Is there a fix for this, or do I have to live with it?
Happened to me too. Got rid of magisk for now so running stock un rooted until this gets sorted. Haven't ran into the issue since un rooting.

Xposed is not yet stable for Oreo. So just get rid of that first. Moreover, it depends on what Magisk version did you flash. V16.0 is the latest stable version and you are recommended to flash it only. I have been using magisk for a long time on both stock and custom rom and never had an issue.

I flashed 16.0 too, but I have to say the issue became real even before I installed Xposed. Guess it's something Magisk-related
Try older Magisk, for example 15.3.
Same to me. Just reboot and it´s fine.

Same. I don't have Xposed or other mods, so I think it's a Magisk's issue.
Made over 20 reboots in order to find the"right" combination of substratum themes the last two days.only 2-3 times i had stucked in reboot. I have magisk, xposed ,gravitybox .
Huh, I get this sometimes too. So it's Magisk v16 you say?

Good idea, will give that a go. I don't use any modules anyway, only use it for Safetynet-friendly root.
Same problem here.

Help with Magisk?

I don't know what is wrong with my phone, I've searched the web for answers only to find nothing, I've asked in other threads and got no answers, I need help. So basically my issue is Magisk on my Mi A1 this issue happens with both 16.0 and 16.4, on the stock Mi A1 rom occasionally when I reboot my baseband and IMEI is unknown and when I reboot it fixes it's self temporarily I know this is not an issue with EFS partition as when I uninstall Magisk everything is fine and on custom ROMs I don't get this issue but a whole other different one. Also on the stock ROM Magisk causes bootloops sometimes which is fixed by rebooting.
When I use Magisk on a custom ROM I get a different issue, whenever I use Magisk to do anything on my device it causes an issue where sometimes when I power off my device it shows the boot animation before powering off.
I'm really sick and tired of these issues and any help would be really appreciated.
I have the same issue with the no imei/baseband in stockrom with magisk
created a thread like you asking for a solution, got not answers, not sure if is because not enough people mod this device or is something else
I for once as soon as I got it, unlocked bootloader and installed magisk and xposed, everything else is stock
issue still persist, you need to reboot again for imei/baseband to comeback

If you want people to help you, you need to give more details. A logcat maybe.

I'm currently running a custom rom and I've discovered that the issue I'm facing there has nothing to do with Magisk, its when I open an app like Titanium backup, even unrooted the app want root permissions causes the boot animation at power off, anyway I'll make a logcat when I get chance.
