Xiaomi Themes MAML syntax

I’m trying to modify Always-on Display / AOD themes, but unfortunately the documentation for Xiaomi Themes is only in chinese. I found the chinese documentation at this link:

In fact most of themes are with chinese characters. So i decided to translate this documentation. I published the work-in-progress translation on github pages at these links: (gihub pages homepage) (translation) (original version that works with google translate)

Xiaomi downloaded files disappear or randomly deleted when moved

I noted a strange issue on my Xiaomi Redmi 9 with Android 11 (i don’t know if the problem is also on Android 10). So, the problem is: when i download a file, if i move it from Download folder to another folder in the internal storage using a file manager different from the Xiaomi one, the file is missing some hours later.

To replicate the issue:

  1. Dowload a file from Google Drive
  2. Create the folder TEST on internal storage
  3. Open Fx File Explorer, open Download folder in the internal storage select and CUT the downloaded file, paste it in the folder TEST in the internal storage
  4. After a day, if you open the folder TEST, the file is missing

[NOTE: for testing the removal, if you don’t want to wait a day, follow these steps: open the Xiaomi Download app, go to downloaded tab, clic on the downloaded file (the file was not found because we moved it), clic on Delete, after that the file will be deleted from TEST folder not from the Download folder where is not]

The workarounds are:

  • Move downloaded files to a folder on the SD card instead of a folder in the internal storage;
  • Use Xiaomi File Manager to move the files from Download folder;
  • Instead of cutting downloaded files copy downloaded files in a folder on the internal storage and than delete it from Download folder.

VoLTE on Xiaomi Indonesian ROM

Sometimes on VoLTE operator, the VoLTE is not working.

I had this problem on Xiaomi Redmi 9 with indonesian ROM (installed for MIUI native call and message apps instead of google ones).

You can solve this problem adding another APN named IMS. This APN must be added only and not selected as active.

So if VoLTE is not working follow these steps:

  • Call: *#*#86583#*#* (enables VoLTE flag in configuration)
  • Add this APN without selecting it:
    • Nome: IMS
    • APN: ims
    • APN type: ims,ia
    • APN protocol: the same of the active APN
    • APN roaming protocol: the same of the active APN
    • change only these parameters, leave the other params unchanged.

NOTE: perhaps this problem is due to the fact that this APN in the EU ROM is already present, but is hidden.

Vontar X1 TV Box Remote Control Conflicting with Seleco SE40C FHDTS TV

I coupled the Vontar X1 TV Box with a Seleco SE40C FHDTS TV. Then there is a problem, some keys of the TV remote control wrongly controls the TV box. When watching movies, lowering the volume of the TV, i get back to the My Apps screen (stopping the movie)

The tv VOL- key, matches the My Apps tv box key.

To resolve the problem, we need to remap the remote control keys of the tv box and ignoring the My Apps command (using root access).

To find the keymapping file, i used the Gamepad Tester app. Install it and go to Test Gamepad. Press VOL+ or a number on the tv box remote control, you will see the name of the device:

Name: sunxi-ir-uinput

So, we need to edit the file sunxi-ir-unput.kl. The file is located here:


To edit this file, install a file manager app with root support. I used FX Explorer. Follow these steps:

  1. On the TV Box install FX File Explorer
  2. Go to the TV Box Home screen > Gear Wheel (Settings) > About > Root switch > Enable > Restart
  3. After reboot, open FX File Explorer, goto Settings > Developer/Root (choose i understand the risk) and confirm
  4. Then in FX File Explorer goto System (root) > (confirm) > More options > Mount Read-Write
  5. Now we need to edit a file, but the System filesystem is full, if you edit a file the file will be 0 byte after saving, if we not free some space
  6. To free some space on the filesystem go to System (root) > system > preinstall and delete some apk of apps that you can reinstall using google play: Firefox, Chrome, KD (kodi)
  7. Now we can edit the file /system/usr/keylayout/sunxi-ir-uinput.kl
  8. Go to System (root) > system > usr > keylayout
  9. Create a backup copy of the file sunxi-ir-uinput.kl. Copy it and paste it in the Main Storage where you like
  10. Open the file sunxi-ir-uinput.kl with FX Text Edit, go to the line:
    key 234 APPS and place a # at the beginning to ignore this key:
    #key 234 APPS or delete the line
  11. Save the file and go back
  12. Reopen the file to check the modification is saved
  13. Go to FX File Explorer home select System (root) > More options > Mount Read-Only
  14. Disable root from TV Box home screen > Gear Wheel (Settings) > About > Root switch and restart

This is the content of the file sunxi-ir-uinput.kl:

CakePHP 4.x Lighttpd Configuration

This is the configuration for running a cakephp application 4.x on the lighttpd web server:

# Enable server modules
server.modules += (
# Directory Alias
alias.url       = ( "/TestCake" => "C:/Users/Nicola/Documents/TestCake" )
# CGI Php
cgi.assign      = ( ".php" => "c:/php/php-cgi.exe" )
# Rewrite Cake Php (with /TestCake subdomain)
url.rewrite-once = (
    "^/TestCake/(css|files|img|js|stats)/(.*)$" => "/TestCake/webroot/$1/$2",
    "^/TestCake/(.*)$" => "/TestCake/webroot/index.php/$1"

The above configuration is tested on Windows. In this example the cakephp application is served on /TestCake subdomain.
