Hi,
I've rooted a SMT575 (samsung tab active 3) by following this tutorial : https://www.reddit.com/user/mschust...ung_galaxy_tab_active_3_smt575_rooting_guide/
Magisk is installed, adb and applications have root access.
I'd like to patch the system in order to get the tablet to boot when the power cable is connected. I've already done that on the samsung tab active 2 by replacing the "/system/bin/lpm" program with a shell script that run "/bin/reboot".
I can't do that on the tab3, even as root I can't modify the /system/bin/lpm file. I tried to make a "magisk module" by putting the modified lpm file in "/data/adb/modules/startup/system/bin". When I reboot the /system/bin/lpm" file is my shell script as expected but when I connect the power cable, the tablet does not boot. I think this is because the mounting of the magisk modules is not done yet.
How can I acheive "boot on charge" on the SMT575 ?
Thank you,

After installing a Magisk module my OS just died, or rather, everything is black but unrelated things such as the widget I have on my lockscreen and the power menu are still visible, I still see me taking screenshots too. But the rest of the OS is black and doesnt seem to respond to gestures. Im able to boot into TWRP too. getting to the point, I want to get my stuff off of it and putting it into my new phone but Im unsure how to proceed. TWRP to PC backup doesnt help cuz, well, yknow. Neither does just dumping the files over a cable, although that seems to be Windows´ fault. Any ideas?

oh Im so sorry, thanks for doing that!
Serious hackers ensure that the door to Android OS always is open before they start hacking Android OS.
This is done by
either
enabling USB Debugging ( AKA ADB ) on Android device - take note that ADB always gets started by device's bootloader when device gets powered on
or
installing LAN Drive ( a SMB server & client ) on Android device what allows one turn the Android device into a Windows PC's network drive.
Both allows one to dump / transfer files located on Android device to Windows PC.
If Android device supports OTG then you also can access Android's user-data when connected by an USB-C-cable.
Hey there!
I wanted to install chroot on my rooted phone [24gb available space + sdcard with 26gb available space]. It didn't work using the "Download latest" button so I downloaded the kalifs-full.tar.gz and put it in internal storage myself, which was working fine. When I got to select the metapackages I selected all of them because I wanted to install everything. After that, it just listed all the metapackages I selected in the Status menu, then it just kinda stops. I rebooted my phone but it says that chroot isn't installed. I also tried waiting for half an hour but nothing really changed. I have tried re-doing it cuppa times but again, nothing changed. The picture below shows the state where it has left off at. I installed the Kali NetHunter module using magisk v24.1
-Greetings

I just found out myself.
1. Installing everything is about 55-60gb which my phone has not enough space for
2. The download I used didn't work, the official one from github worked
I have two question,
My first question is simple:
The device I have has a customized android rom and adb is not active. When the operating system wake up, it automatically launches an application. I can't go back to the home screen because the back button only works inside the app and won't let me go to the home screen.
Is there any way I can return to the home page or activate adb ?
My Second Question:
I pull the apk of the application that works on such devices, mod it and reupload it to these devices.
I think I have to use adb for this.
Is there any other way to pull an apk from custom and blocked android rom, change it and upload it again?
thank you.

Hello. I've got a backup of
Code:
mmcblk0
It's probably encrypted, but I'm not sure. If it is, I do have the password, but then I wouldn't know where to insert it.
Is there any detailed tutorial on how to mount this file and work with it? If it's a Linux solution then preferably some guide or tutorial on how exactly to figure out this mess.
Thanks for any help.

I don't know what's the goal but you can extract the userdata partition from disk image with dd. the output of parted is in bytes, must divided by block size of your choice (bigger bs is faster)
Code:
parted mmcblk0 unit B print
dd if=mmcblk0 of=userdata.img skip=$off count=$len bs=$bs
another way is boot into TWRP from fastboot and pull the partition image directly.
Code:
fastboot devices
fastboot boot twrp-3.6.2_9-0-lavender.img
adb devices
adb pull /dev/block/bootdevice/by-name/userdata
Note: even if the partition image is mountable, the files are encrypted and manually decryption requires healthy keystore (not included in mmcblk0) and the device of origin itself.

I have a HTC Desire 650 running android 6 and I am trying to root it and also keep the original recovery.
I have found this thread: https://forum.xda-developers.com/t/root-htc-desire-650.3713325/ and apparently someone built a twrp for it. Doesn't that need a root in the first place to extract the kernel source?
Anyway, are there any apps or known vulnerabilities that would allow me to root the phone or at least extract the recovery image?
The problem is that I couldn't find any stock rom images or anything else for this phone. I was only able to unlock the bootloader.

Only to clarify things:
1. Recovery is a small and independent operating system that is set up in its own partition in many Android smartphones and tablets.
The "Recovery mode" is useful for you if you want to access the Android system of your smartphone or tablet beyond the conventional settings.
Since the recovery system is on its own partition next to the actual operating system and is thus intact even after a virus attack, it is often used for system repair.
2. Android's bootloader is a program that is responsible forbooting Android device.
3. Rooting is how you get complete access to everything in the Android OS, and those elevated permissions allow you to change it all. Root, at least the way I'm understanding it, is the superuser.
When you root your Android, you're simply adding a standard Linux function that was removed by OEM. A small file called su is placed in the system and given permissions so that another user can run it. It stands for Switch User, and if you run the file without any other parameters, it switches your credentials and permissions from a normal user to that of the superuser. You are then in complete control and can add anything, remove anything, and access functions on your phone or tablet that you couldn't reach before. This is pretty important and something you should think about before you begin.
To root Android OS it's neither necessary to unlock devices bootloader nor to install TWRP: this is an obviously not eradicable old nurse's tale!
