Disable Android Device Manager Wipe (Stock ROM+Root+Xposed) - Android Q&A, Help & Troubleshooting

Hi,
I have recently went back to stock from CyanogenMod. I installed root and Xposed on it (for some other purposes). One of the things I liked about CyanogenMod was that you could not enable remote wipe and erase remotely (a security concern, in my opinion) ever since I've heard of those remote wipe hackers who wiped a bunch of iPhones, I've been paranoid. I'm encrypted with a relatively strong password.
I have already tried to disable remote wipe by disabling the Android device manager device admin (didn't work; you can press the "enable remote lock and erase" and it gets its admin back), I tried to disable remote lock and wipe from Android Device Manager through Google settings, with the same result.
It looks like the only way to truly disable this is to flip some switch I've not come across or uninstall/replace the framework for remote wipe/erase.
How do I disable remote wipe and erase (while leaving GPS and ring on) from Android device manager, without allowing it to turn back on?

[Q] Anti-Theft Application

Hi All,
I am looking for a good anti-theft application.
Requirements are:
1. Wipe Data Remotely
2. Lock Device Remotely
3. Persist after Wipe
The first 2 are easy, most do this.
The only one I have found that does point 3 is cerberus (cerberusapp.com) you can install it with root access, or from CWM Recovery.
Does anyone else know of any others? I found cerberus to be a bit unreliable.
So,
Went for Cerberus after 2.0 was released. Fixed issues on my ICS Rom.
Point out works great, you can send a remote wipe and then put a code on it and enable GPS tracking. All data is safe and they can't use the phone
I don't know if it is your case (cause i cannot see what device do you have) but with samsung devices (like sgs2 for example) you can enable remote control inside settings/location & security then after registering on samsung site you can do all this stuff using www.samsungdive.com
It's easy and it works 100%
Phone locator pro for me, more reliable than Samsung dive, and just works, note, you have to reinstall it after flashing
Sent using TCP/IP
Using CM9 Alpha, so Samsung choices don't work
I need it to work after data wipe.
Ie Phone is stolen, so Wipe > Lock > Try and locate.

Phone Locator Software with Security

Hello Everyone,
I am searching for a good phone locator software which would be helpful when you have lost the phone but with the following security in it :
1) Disable or password protect factory reset on device.
2) Disable or password protect download mode on device so tat any1 else cannot flash the rom.
the above two things can easily remove the phone locator app on any device
The closest I can think of is Avast Anti-Theft that can be installed to system as separate from the main Avast app and hidden to prevent uninstallation and factory reset.
Unfortunately it requires a rooted system.
One of the options is to disable entry to settings and disable USB debugging, I am not too sure if it interferes with Download mode (?)

OnePlus One, CM-13.1.2 stock room. Phone hangs every time after reboot

Hello,
For a long time I'm using my good old friend OnePlus One, it works great to me on stock AOSP CM-13.1.2 until yesterday. I fail in the name of good and terrible thing has happened xD.
I wanted to stop draining my battery by apps which all the time were using GPS service to track my location so I started to make some change in settings -> privacy guard settings -> Location permission.
I tried to change the permission to those apps from "Allowed" to "Always ask". I do mistake and change permission to Google Play Services. After that I restart my phone. Now every time my OnePlus One is stuck/freeze after booting screen and I see only black screen and popup window in center with requests to give Location permission to Google Play Service.
Touch screen not working when is press to Allow, It cant go ahead to lock screen.
My phone is not rooted, locked bootloader, no TWRP, only stock Cayanogen recovery with options:
Reboot system now
Apply update -> Apply from ADB->ADB Sideload
Factory reset -> Full factory reset or Wipe cache partition ( I dont want lose my data on phone)
Advanced-> Reboot recovery
Advanced-> Reboot to bootloader
I read on internet that I need to modify or delete /data/system/appops.xml file
What can I do now, how can I do this modification without losing data.
Can I do it from shell console ADB? and which option I have to choose in recovery to connect my laptop OS: win XP with OnePlus One?
I read that i can do it by TWRP recovery but i dont have it on OPO. Can I safely flash it to phone without losing data? Bootloader is locked.
Is there any tutorial how to do it safely? How to Delete or download, modiffy and replace file /data/system/appops.xml using ADB commands, backup my personal data to PC, connect with phone by ADB with computer.
Any help needed. Sorry for my bad english.
Best Regard

Disable Slide to unlock and decativated settings at Android 8

Hello guy`s
i`m searching since days for a solution for my Android car system.
It has Android 8.1.0 installed, i can access the filesystem via adb root, the system itself is not rooted.
I have two issues with the device.
since a factory reset, when booting the system it does start into the "normal" slide to unlock screen, before the reset it booted directly into the Car GUI.
I searched also for disabling this, but only found how to reset or delete the passwords, and disable it on old Android 2.3 4.0 or 5, but not on Android 8.
it would now be easy said to just disable it at the system security settings under Display lock, but here is the second issue, the option seems to have been disabled by the manufacturor.
the same is with some other Option menu`s that are missing at settings.
i`m not that firm with android os itself, so i can`t finde the right command or modification to change this.
can someone help me how to disable slide to unlock, and how to reactivate deactivated system settings ?
sincerely Chri

How do I format/delete system partition?

Hey guys.
I have encountered an EXTREMELY frustrating problem with android 9/10.
I was messing with some options in my phone like 'data usage' and 'permissions' & disabling some apps using adb & greenify.
All of this was common stuff that I'd always mess with, on Oreo.
On oreo when my system apps 'wigged out' I could flash my stock rom a couple times and the system apps/services would go back to normal (Inactive).
On android 9/10 though, I notice that when these same system apps go haywire there is no way to reset them back to their default behavior.
My phone is running about 9 extra services than it should be (mostly samsung services). Also, my battery drain is draining about 25% faster than it should be.
Things I've tried:
1. Wipe data/factory reset.
2. Wipe cache.
3. Reset app preferences from app menu.
4. Reset all settings from reset menu.
5. Flashed firmware multiple times, using odin.
6. Flashed combination rom, to clear google data (this one fixed some of the rogue services, but not all of them).
7. Install combination rom and try factory reset from within the rom.
(Next, 8), I'm going to try Smart switch (PC) to reinstall firmware.
Some of the rogue services I'm referring to:
com.qualcomm.atfwd
com.qualcomm.embms
SVC Agent
Call & text on other devices
com.sec.imsservice:CloudMessageService
android:drmService
Software update
Bluetooth service
Samsung Push Service
Smart Switch (fixed by #6)
Samsung cloud (fixed by #6)
Find my mobile (fixed by #6)
(All these were inactive by default, but after disabling some samsung system apps these are now permanently stuck on).
(I'd like to remind you, I could fix all of the above services from running on oreo, with a simple double firmware flash).
I'm thinking I need to wipe my "system partition", but without root this seems almost impossible.
Has anyone encountered this issue before?
Does anyone know how to wipe/format system partition without root?
Any other suggested ideas would be huge. Thanks.
