Entware and pyLoad on Android 7.1 TV Box

Description:
Entware is repository full of apps for embeded linux like android on tv box. I have prepared installation script to install it from scratch because android is different. You have to rebuild folders in root on every reboot. Root partition is rebuilt on every boot from the image. I will use /data partition to store files (path /data/opt) and mount –bind on /opt.

Check your architecture of processor and os. My TV Box has Amlogic S912 armv8 – aarch64. Just run two commands:

uname -a
cat /proc/cpuinfo

Processor : AArch64 Processor rev 4 (aarch64)
processor : 0
processor : 1
processor : 2
processor : 3
processor : 4
processor : 5
processor : 6
processor : 7
Features : fp asimd evtstrm aes pmull sha1 sha2 crc32 wp half thumb fastmult vfp edsp neon vfpv3 tlsi vfpv4 idiva idivt
CPU implementer : 0x41
CPU architecture: 8
CPU variant : 0x0
CPU part : 0xd03
CPU revision : 4
Hardware : Amlogic
Script will download binaries for aarch64. For another you have to change URL= and DLOADER and busybox binary.

Source of the install script and repository: http://bin.entware.net/aarch64-k3.10/installer/

First you have to root your device!

On windows you will need Minimal ADB: https://forum.xda-developers.com/showthread.php?t=2317790
On linux just install android-tools-adb android-tools-fastboot.

1. Install WiFi ADB: https://play.google.com/store/apps/details?id=com.ttxapps.wifiadb
   or http://www.mediafire.com/file/zki6u53zom8d684/WiFi_ADB_2.0.1.zip
2. Run WiFi ADB and connect to via adb:

   adb connect ip:5555

   adb connect ip:5555

   Accept and remember connection on TV Box

3. Download script (source code is on the bottom):
4. Download busybox for armv8 because my wget on TV Box was broken (it can’t finish any download):
   https://www.busybox.net/downloads/binaries/1.28.1-defconfig-multiarch/busybox-armv8l
5. Push the script from disk to TV Box:

   adb push C:\Users\user\Desktop\ent-armv8-android.sh /storage/emulated/0/

   adb push C:\Users\user\Desktop\ent-armv8-android.sh /storage/emulated/0/

   If there is permission denied use another directory.

6. Push busybox binary:

   adb push C:\Users\user\Desktop\busybox-armv8l /storage/emulated/0/

   adb push C:\Users\user\Desktop\busybox-armv8l /storage/emulated/0/

   If there is permission denied use another directory.

7. Run ADB shell an run all below as root with su:

   adb shell su

   adb shellsu

8. Move script from emulated internal memory to another without noexec flag:

   mv /storage/emulated/0/ent-armv8-android.sh /data/local chmod +x /data/local/ent-armv8-android.sh

   mv /storage/emulated/0/ent-armv8-android.sh /data/localchmod +x /data/local/ent-armv8-android.sh

   If there will be error Read only file system, just remount it to write and run again above commands:

   mount -o rw,remount / mount -o rw,remount /system

   mount -o rw,remount /mount -o rw,remount /system

9. Run the script:

   /system/bin/sh /data/local/ent-armv8-android.sh

   /system/bin/sh /data/local/ent-armv8-android.sh

   If there is a /bin you will be asked for delete. Do not delete it if it is not empty, just remove that part from script. It will delete /opt as well. Then will create neccesary folders and instsall opkg, basic enteware and dropbear for SSH.

10. Script will create autorun script in /system/etc/init.d/entstart.sh It has to be run every boot to make entware and entware services to work. If your Android rom support init.d you dont’t have to do nothing.
11. Another Auto Start options:
    • Try to enable init.d support with Uni-Init apk or sh script: https://forum.xda-developers.com/showthread.php?t=1933849 It does not work for me.
    • Try to modify init rc scripts. (it does not work for me i’ve still got init: Service exec () does not have a SELinux domain defined.)
      1. Try to rebuild image to modify /init.rc
      2. Modify init scripts from /system/rtc/init/
    • Check for any autorun static script:
      https://android.stackexchange.com/a/69194

      $ find /etc -type f -perm +110 $ find /etc -name "*rc" $ find /etc -name "init*" $ grep -R /data /etc $ grep -R /system /etc

      $ find /etc -type f -perm +110$ find /etc -name "*rc"$ find /etc -name "init*"$ grep -R /data /etc$ grep -R /system /etc

      I have checked either:

      dmesg | grep .sh

      dmesg | grep .sh

      I’ve got few candidates:

      /system/bin/install-recovery.sh
      init: cannot find /system/bin/kodi.sh’ (No such file or directory), disabling ‘kodiconf’
      init: cannot find ‘/system/bin/dtvdata.sh’ (No such file or directory), disabling ‘dtvdatas’
      init: cannot find ‘/system/bin/factoryreset.sh’ (No such file or directory), disabling ‘factoryreset’

      You can try run init.d
      First use app Uni-init to create all files ant contexts: https://forum.xda-developers.com/showthread.php?t=1933849 and hen link your built-in in rom script to sysinit created by this app:

      ln -s /system/etc/init.d/sysinit /system/bin/kodi.sh

      ln -s /system/etc/init.d/sysinit /system/bin/kodi.sh

      now you have properly working init.d.

      There is exmaple of script to run all init.d if your need yor own:

      AUTO_START=/system/bin/autostart.sh touch $AUTO_START echo -e "#!/system/bin/sh" > $AUTO_START echo -e "\n" >> $AUTO_START echo -e "sleep 1" >> $AUTO_START echo -e "export PATH=/sbin:/system/sbin:/system/bin:/system/xbin" >> $AUTO_START echo -e "/system/bin/busybox run-parts /system/etc/init.d" >> $AUTO_START echo -e "\n" >> $AUTO_START chmod 0755 $AUTO_START

      AUTO_START=/system/bin/autostart.shtouch $AUTO_STARTecho -e "#!/system/bin/sh" > $AUTO_START echo -e "\n" >> $AUTO_START echo -e "sleep 1" >> $AUTO_START echo -e "export PATH=/sbin:/system/sbin:/system/bin:/system/xbin" >> $AUTO_START echo -e "/system/bin/busybox run-parts /system/etc/init.d" >> $AUTO_START echo -e "\n" >> $AUTO_STARTchmod 0755 $AUTO_START

      If SELINUX blocked you…

    • Just install app SManager: https://play.google.com/store/apps/details?id=os.tools.scriptmanager or http://www.mediafire.com/file/skh4dkla2e1d5bo/SManager_3.0.7.zip and add /system/etc/init.d/entstart.sh to autostart with su privileges. (to do that click still upper directory even there is access denied)
12. Modify /system/etc/mkshrc and add
    export PATH=$PATH
13. Install pyload:

    opkg install ca-bundle ca-certificates opkg install pyload opkg install python-pyopenssl openssl-util opkg install duktape opkg install pillow tesseract opkg install python-crypto opkg install unrar unzip opkg install p7zip pyload --configdir=/opt/var/pyload

    opkg install ca-bundle ca-certificatesopkg install pyloadopkg install python-pyopenssl openssl-utilopkg install duktapeopkg install pillow tesseractopkg install python-cryptoopkg install unrar unzipopkg install p7zippyload --configdir=/opt/var/pyload
