Rooted phone crashes when altering system files - Android Q&A, Help & Troubleshooting

Hello, I've searched up and down and can't find anyone else with this issue. I'm pretty new to rooting/flashing roms/etc but I'm trying to learn as fast as possible.
My current device: Blu Life One x2 Mini
My problem: I've tried a variety of roms, both custom and stock, as well as several different rooting techniques and across all setups I'm seeing the same issue. Any application I check with says that the phone is rooted and my system folder is set to read/write. If I attempt to uninstall a system application, change a file in the system folder, or even change the permissions of /system/ the device will freeze and then after a few seconds reboot. It seems that applications that alter /system/ also generate this crash, for example installing busybox from the application causes a crash.
Setups I've tried:
-Stock rom with Magisk
-Lineage OS 13 with Magisk
-Lineage OS 13 with SuperSU and Magisk (why not?)
-Lineage OS 13 with Lienage root add on (what I'm currently using)
The device operates fine outside of this. Any help is appreciated!

[Q] android:persistent not working on Lollipop?

Hello -
I hope someone can help with making my app persistent in my custom ROM.
In the Android manifest, I have flagged my application as "persistent", so that it automatically restarts if it crashes, is less likely to be killed by the system, etc. I know that normal applications cannot use this setting, but I am working on a custom ROM, and I load my application into the priv-app folder, and so I am able to use it.
This works perfectly well on pre-Lollipop phones. However, when I build my APK into an Android 5 ROM, the "persistent" setting is no longer honoured. I can use 'dumpsys activity' to verify that my app is persistent on Android 4.4.4, but not on Android 5.0.
Is there some additional requirement for persistence in Android 5? I see that some system-supplied apps are still persistent, so it's not as if it's completely impossible. Thanks.
Figured it out myself eventually - turns out it was to do with selinux file permissions. I had to use chcon to copy the selinux file context from another file in the priv-app folder to sort it out.
You should put [SOLVED] in your thread title

Remix OS 2.0.205 rooted, after updating su, closing any app reboots

I have install and fought (and it has been a fight), to get Remix 2.0.205 installs in VMware and rooted , I actually wrote a script see the rooting thread to mount system rw to allow SuperSU to be updated. However when all is said and done yes it boots, but once rooted and if you update SuperSU as needed, the product is worthless as I'm unable to do anything without rebooting, for instance close chrome (reboot), install apk (reboot, also the app it is not installed), close settings, and click on some icons on the UI such as O.
So basically while you can configure and setup Remix in VMware and even root it, you can not use the OS once rooted, so it is basically useless, if you need root (who don't need root).
Tricks to getting it to work in VMware (that I've discovered):
Use a 32 freebsd as a base (not sure why that matters but it seems to)
use SATA drives, do not use GPT partitions.
Disable advanced graphics
I never could get Remix in VMWARE to run at anything other than 800x600 resolution, no matter what I tried changing DPI only changes text size did not for the display size used, I did not spend time fixing this as I can not used the rooted Image without it rebooting.
Can anyone explain why after updating SuperSU Remix OS fails to function, before updating SuperSU it had no issues, so it has something to do with updating the su binary (normal update as there is no recovery).
Thanks,
ERIC
did you replaced initrd.img with the modified one ?
looks like your system.img still has read-only

Yes, I actually wrote a script to adjust the mounting of system.img, when read-only you can not even update SuperSU (fails), Also based on the use of the root prompt (F1) system is mounted read-write.
Actually it is not the OS that restarts, based on uptime but the Remix GUI.
Thanks,
ERIC
The firt U need Root your deives
The Su does not matter what happens
How to adjust the DPI screens
This index higher DPI interface will more loudly and more smooth, but not too big just as well as too large, then everything will be transferred to the interface of the phone should not be spending delectable . DPI is also to small too much content is displayed but text and icons are too small, so we can not see clearly, have pressed themselves into very uncomfortable eyes. Ideally for the middle in a bit tasty.
To change the DPI, the request must be root Remix OS, then you install the app on the Play Store TexdroidDPI about to reset. Extremely simple way of correction, simply enter your desired DPI on, then restart the operating system is finished.

Direct TV Error 40 Root Check bypass on Amlogic s905x (TX5Pro, Marshmallow)

I downloaded the DirecTV Now app on New Year's Eve hoping for $35/cable. Instead, I was greeted with the same Error 40 that everyone with a rooted device got. It took me a couple of days of researching and playing and reflashing and..., but I've finally figured out the simple(r) method to bypass this stupid root check for DirectTV Now (AKA Error 40, QP1005)
This applies to the TX5Pro, but it should work on any s905x based AMLogic SoC running Marshmallow 6.0 (A95X, CQ9, TX5, TX3, X96, NEXBOX, +many more.) As I understand it, they all have similar Android builds using the p212 board and firmware. I also have a M8S s812 running Kit-Kat 4.4.2 that I'll work on breaking, next.
First things, first: If possible, find your firmware and do a clean flash. Not a requirement, but if you've been playing with this for a while and you've ended up here, you've probably mucked up your /system files in some way or another. I managed to screw up my su binary location a few times and couldn't get it back without a lot of work. Reflashing was a three-minute, headache-free task.
That said, you'll want to adb over tcp/ip as these devices don't like to play the USB cable game.
Code:
adb connect deviceipaddress:5555
Follow up with
Code:
adb shell
and
Code:
su
to get into a root shell (if you don't get one by default.) Mine came with SuperUser from ClockworkMod preinstalled as a system app. Mount your system folder
Code:
mount -o rw,remount,rw /system
and edit your build.prop file with Vim.
Code:
vi /system/build.prop
If Vim is new to you, search the interwebs for a Vim cheat sheet.
Here's the trick with this... DirecTV Now's shared object file in lib/armeabi/libdrmagent_downloadable_jni.so looks for a few keywords within a few properties. Those properties are:
Code:
ro.build.product
ro.build.tags
ro.build.type
ro.build.display.id
...and the keywords are:
Code:
"release-keys, OnePlus2, OnePlus, Z26CL, STUDIO_C, user" are keywords that it favors, while "cm, cyanogen, cyanogenmod, debug, userdebug, A0001" are disqualifying keywords. Supposedly, "test-keys" is a bad word, too.
In my case, I needed to edit my build.prop to eliminate any sign of the bad words. Example:
Code:
ro.build.display.id=p212-userdebug 6.0.1 MHC19J 20160909 test-keys
to
ro.build.display.id=p212-user 6.0.1 MHC19J 20160909 release-keys
Run through the file and replace anything that says userdebug with user and test-keys with release-keys until you get to "#end build properties" Then save and reboot.
After reboot, install Hide My Root (I used the one from Amphoras) and hide the Su binary. This is where things might be getting tricky for some of you... on the TX5Pro, the SuperUser app is a system installed app, meaning it can't be uninstalled (it can, but it's not exactly a simple task for everyone) so you'll need to go into settings -> apps -> superuser and disable the app from there. Reboot again. Now, with the su binary hidden and the app's manifest not showing up in the system, the error 40 message should go away. This option will allow you to quickly restore su and SuperUser without needing a bunch of additional steps. You'll still need to set the device location service to "battery saving" (or use mock locations) but that's a simple task anyone can figure out.
The app is a choppy on high def feeds for some reason. I can't tell if this is processing/memory issue or a feed (wifi) issue. By default, the app doesn't work on ethernet, meaning you'll have to use wifi until you can fix that issue. But hey, one thing at a time, right? Anyway, I hope this helps anyone with this particular headache.
Thanks for pointing me in the right direction...
Got DirecTV NOW working on my nexus 6 running pure nexus ROM... I just did the edits with super su root and root explorer. Then disabled super su and rebooted.
Now to update the the build.prop files on the lineage os 13.0 nexus 10, and my wife's kltevzw (on ting gsm network) running lineage os 14.1

Any chance that you tried this out with Data Free TV/"Sponsored Data" with an AT&T wireless account? i.e. running the box through a Cellular Hotspot or tethered to your phone. I've been looking at if one could use one of therse Android TV Boxes to basically get Data Free TV.
my live tv app detect root try with magisk also but no success in my s905x help me guys

I edited my build.prop files to try and "hide" the root and I still get the error. I also tried root cloak with xposed and still nothing
Thanks so much
This really helped. I used Xposed module to hide those keywords. Worked a charm!

Local root for the Amazfit watch (SuperSU 2.79)

Hello all, I got my Amazfit Pace a few days ago and the first thing that I wanted to do after flashing PACEified was get proper on-device root, as you know right now PACEified comes with adb root shell so we can modify the watch however we want from and adb shell but that means we're always dependent on another device for doing so, apps on the watch have no way of getting root access.
I am actually amazed that no one else even seemed to have any interest in achieving this as it was somewhat easy for me to figure it out and now I'm sharing it with y'all.
Requirements: being on a ROM that has adb root (ex: PACEified) or ability to boot the temproot kernel.
WARNING: If the stock kernel has dm-verity the temproot then install SuperSU method will lead to the device refusing to boot, I do not know whether it does or not.
Disclaimer: I am in no way responsible for any damage this can or will cause to your watch and/or phone, you are the only one responsible for your own actions.
Anyway here's the steps to getting SuperSU 2.79 fully working on your watch:
Download the attached zip file.
Copy the zip file to the watch.
Open a terminal/cmd/powershell in the folder where your adb binary is located.
Run the following commands in order:
Code:
adb root
Code:
adb remount
Code:
adb shell
Now you are running shell commands on the watch itself so do:
Code:
busybox unzip /sdcard/SuperSU-2.79-amazfit.zip
Code:
cd /sdcard/supersu/
Code:
sh root_amazfit.sh
Done, reboot and enjoy!
I hope this helps others as it did help me and I do hope I didn't make any mistake.

Everyone else that I can't remember right now
List of useful root apps for the Amazfit:
MiXplorer-useful file manager with addons and root file management options: https://forum.xda-developers.com/showthread.php?t=1523691
Kernel Adiutor 4 Wear-very popular kernel options management app, won't give too many options since the stock kernel is actually quite limited but still allows tweaking a few things like changing the schedulers and their options, enabling init.d and other such stuff: https://forum.xda-developers.com/android-wear/development/app-kernel-audiutor-4-wear-t3126122 (I only tested this version but the latest normal Kernel Adiutor version might also work perfectly since the interface seems pretty friendly with low resolutions)
Advanced Settings for Watch-provides a plethora of options like Bluetooth and WiFi settings management, reboot menu and most importantly PACKAGE MANAGEMENT and by that I mean it doesn't just have the normal app settings menu that allows you to clear data/cache, force stop or disable/uninstall apps but ALSO INCLUDES A PACKAGE INSTALLER for installing apks straight on the watch: https://play.google.com/store/apps/details?id=com.sssemil.advancedsettings&hl=en (get the wear apk from inside the main apk, it is located in /res/raw just open the phone apk as an archive also WARNING: many menus/options make it crash cause this is not Android Wear)

Same as on any other rooted Android device.
A few apps I have on the watch that use root are:
MiXplorer-file manager
Kernel Adiutor-can improve battery life/performance by messing around with it a bit
Root Essentials (the wear part sent from inside the phone apk)-it's great for uninstalling apps and such
Hello. Stock ROMs can boot "temproot kernel"? Could you please like to where it's explained? Thanks.

Nice.
MiXplorer is my mobile favourite Android explorer.
I don't know the other apps, i must learn about it.
Any suggestions about them, Kernel auditor seems very interesting. I have very much problems with my Amazfit battery, last month suddenly i don't get more than 2 days of autonomy
Thx.

Stock ROM can boot temproot kernel only if old enough version to not have the bootloader locked OR you unlocked the bootloader after, to get the temproot kernel go to the PACEified thread and read the install instructions, it has you booting the temproot kernel on order to flash it and it might be possible to just boot it, root and reboot but I am not entirely sure, if the Amazfit has dm-verity it will refuse to boot after altering the system, I actually didn't think about that when I wrote this guide cause it was 5AM so would recommend flashing a custom ROM.
@Neuer_User does the Amazfit have dm-verity?
Also would you consider adding SuperSU to PACEified in the future?
Double post cause mobile XDA is messed up, delete.

To be honest MiXplorer just about works but isn't really 100% usable cause things don't fit on screen, looking for a better root file explorer for the watch.
The stock kernel doesn't really allow you to control much cause the stock kernel doesn't seem to have too many features but can still change governor and a few other stuff and if nothing else it can enable init.d if you don't already have it enabled, I use the Kernel Adiutor 4 Wear version but TBH I think the normal one should be just as usable.
For your battery problem you could try deleting some unneeded apps like the Mi Home or the Chinese radio one (if on Chinese ROM/PACEified) and maybe Greenify will also work but wouldn't really put my bets on it, perhaps try using some battery saving scripts?
Right now I'm looking for an apk installer...I have a solution already but it's probably the worst one possible: a init.d script that checks if there are apps in a folder on the internal storage then installs all of them and deletes the apk files but that means you need to reboot in order to install apps, could make crond run the script every hour or so but that would also not be too convenient so either a script runner or a apk installer would be best.
BTW after uninstalling apps from the watch using a root app you need to crash the launcher or it will still show the icons for the uninstalled apps.
Also I'm working on improving the script to add safety checks (if someone tries to run it without the other files in the same folder right now it would most certainly end up in a mighty bootloop, fortunately a bootloop with adb access so easy to fix but still not great, I made that script in like 5-10 min after I manually did it on my own watch) and add more features like installing a newer busybox version and linking missing applets (unzip for example).
Updated 2nd post with a few useful apps, one of them finally giving us the power to install apps straight on the device, will publish the new version of my script in a few days, have been working on adding A LOT of new features and now I kinda need to concentrate on the project for my Android class for a bit, sorry for the delay.

Hi Ranomez,
When do you plan to publish the new script for local root?
Thx in advance.
Merry Xmas.

Most probably next week, haven't really had time to work on it with the last week of college before the holidays and the fact that I bought Xenoblade Chronicles 2 on launch day and it's been eating most of my free hours, lol, sorry for the delay, anyways the current script still works for simply rooting but will give a no such file or directory error if init.d isn't already enabled, just ignore that.
Thank you @Ranomez
I've just tried your local root using the temproot kernel on the latest stock rom, and it worked great. So, I can say my pace doesn't have dm-verity enabled?
btw, SU was added to Stockfied, Pacefied and Stratosfied, just needs to be enabled.

Busybox - Incorporate custom binaries

Hello,
I was just wondering, how would I go about adding several binaries to a busybox installation.
For ex: I would like to add "exa" to use instead of ls, "fd" in replacement for find, the text editor "micro", as well as possibly git (although I would guess that adding too many additional binaries would make busybox too dense)
I know a good deal about android development, c programming, and shell scripting, so I don't by any means expect someone to "do" this for me or recompile it for me. Just the steps necessary (if it's possible to do this effectively), or an alternative solution in which would accomplish this objective.
Currently I have a (working) solution using termux boot, that copies the files to "/system/xbin" on boot. It works fine... however I can't help but feel like this is not the best way to go about it.
If it matters: I am on a Google Pixel, rooted, on a custom rom (resurrection remix, android oreo build) with TWRP recovery installed.
Thanks,
HLTDev
