Tweak init.d script prevents boot

Hello everyone!
I made this script for myself from stuff I found online. But when I put it into init.d the phone stops booting before the cyanogen logo comes up (on the second LG logo). I can't figure out why... However it works (the settings are applied) if I run it with adb once the phone is booted.
This is the script:
Code:
#!/system/bin/sh

user.feature.lgdrm=false disable DRM Service, so you can not use the default phone ringtones and notifications but if you are planning to use your custom files without DRM then there are no problems.

samsung ultra power save mode

Can I use gasket to enable upsm at 5% ? I'm complete noob so will need talking through thanks

ROOT + shell
echo "0" > /sys/devices/virtual/mdnie/mdnie/accessibility
echo "1" > /sys/devices/virtual/mdnie/mdnie/accessibility
echo "2" > /sys/devices/virtual/mdnie/mdnie/accessibility
echo "3" > /sys/devices/virtual/mdnie/mdnie/accessibility
0 : Normal Screen
1 : Inverted Colors
2 : Ultra Power Save Mode
3 : Screen off but not locked and touchscreen is still working

Thanks for reply but that means nothing to me?

No one with a basic guide

Do you have ROOT?
If not, you can"t auto turn on UPSM.

Yes I have root

@bandit250
you are still interested?

Yes please

First, Make a test.
Task:
1. Run shell [mark ROOT]
Command:
echo "2" > /sys/devices/virtual/mdnie/mdnie/accessibility
Push play
upsm should turn on.

/system/su.d

Hello. I found same questions in other topics, but couldn't find answer.
I would like run script from /system/su.d folder:
Code:
#!/system/bin/sh
echo 0 > /sys/fs/selinux/enforce
or
Code:
#!/system/bin/sh
setenforce 0
and I even tried to run test script:
Code:
#!/system/bin/sh
touch /data/local/tmp/test.txt
echo "test" >> /data/local/tmp/test.txt
But no one of them works. I tried different names for files, gave different chmod (644,700,755). Nothing helps me to run script.
Mb somebody can give me advice what's problem can be?

The file is called 00mountsd and is used to give access to exfat microsd on stock android 5.1 running on a Chuwi Hi10pro tablet with cherry trail z8350 cpu. I used this on a previous version of the tablet and it worked fine although that tablet came with RemixOS.
The file runs without errors when run manually and succeeds at it task
ls -lZ returns this -rwxr-xr-x root root u: object_r:system_file:s0 00mountsd
I'm running SuperSU Free v2.79 everything else works fine.
Any ideas?

How To Guide How to configure the WiFI in Android via script

In the current version of Android the WiFi configuration is stored in the file
/data/misc/apexdata/com.android.wifi/WifiConfigStore.xml
e.g.
Code:
ASUS_I006D:/ # ls -lZtr /data/misc/apexdata/com.android.wifi/WifiConfigStore.xml
-rw------- 1 system system u:object_r:apex_system_server_data_file:s0 4884 2023-01-29 08:55 /data/misc/apexdata/com.android.wifi/WifiConfigStore.xml
ASUS_I006D:/ #
The file is in plain ASCII xml format so it can be processed by any executable to change text files (editor, sed, etc).
But IMHO it's better to configure the WiFi manually via GUI and then use the file WifiConfigStore.xml with that configuration for configuring the WiFi via script. Therefor I use this code in the post install script to install and configure my phone (see How to install and configure the Android OS via Script):
Spoiler: script commands to enable and configure WiFi
Bash:
#
# sample post install script for the customizing of the phone
#
# This script will be copied to the phone and executed there
#
# The script is executed by the user shell; use "su - -c <command>" to execute commands as user root
#
echo ""
echo "*** Postinstall script is running ..."
echo ""
# ... other customizations ....
#
# create the WiFi config file
#

#
echo "Enabling WiFi ..."

# Now reboot the phone to activate the new WiFi config ..
#

i=0
while [ $i -lt 15 ] ; do
(( i = i + 1 ))
printf "."
sleep 1
done
printf "\n"
echo "Now rebooting the phone ..."
reboot
#
Notes:
Be aware the the file /data/misc/apexdata/com.android.wifi/WifiConfigStore.xml contains the passwords for all configured WLANs in plain text.
There should be a command to force Android to reread the file WifIConfigStore.xml but I don't know that.
Android can be forced to re-read the file WifIConfigStore.xml by killing the process system_server, e.g:
Bash:
pkill system_server
But that is more or less a warm reboot and I do not know what other side effects that restart triggers
There is an app to configure WiFi via adb command
https://github.com/steinwurf/adb-join-wifi
Bash:
adb shell am start -n com.steinwurf.adbjoinwifi/.MainActivity -e ssid myssid -e password mywlan_password -e password_type WPA
The app works but unfortunately it does not support enabling the setting to use the device MAC instead of the random MAC so it's not usable in my environment.
Another app to configure WiFi via adb command is available here:
https://github.com/pr4bh4sh/adb-wifi-setting-manager
Unfortunately that app also does not support enabling choosing the MAC address for the connection.
There is also a script to convert an old Android wpa_supplicant.conf file to the newer (post-Oreo) WifiConfigStore.xml file (not tested):
https://github.com/mnalis/android-wifi-upgrade
It's also possible to use the command wpa_cli to configure WiFi but be aware the wpa_cli only works if selinux is (temporary) disabled, example:
Spoiler: wpa_cli example
Code:
ASUS_I006D:/ $ su -
ASUS_I006D:/ #
ASUS_I006D:/ # setenforce 0
ASUS_I006D:/ #
