Re: PSA: Batch script mirroring Android on the desktop over Wi-Fi (without USB)

Cross-posted to 3 groups.

If something takes 20 steps, we reduce it in half, and if it takes 2 steps, 
we still reduce it in half, until everything we do, is a single quick step.

To that end, I've updated the adbconnect.bat so that it handles any IP 
address, any set of ports & any password prompt which ADB over Wi-Fi needs. 

In addition, I was able to figure out a way to eliminate the scrcpy 
console, where I had been using Herbert Kleebauer's ShowWin() previously.

The script below answers two questions anyone would have, which are:
 Q: How do we connect desktop adb to Android Wi-Fi in the shortest steps? 
 Q: How to we mirror Android onto the desktop without an open console?

Both issues are solved below, but, as always, please test and let me know 
where/if I err or where/if I've omitted something that is critical to know.

  :: adbconnect.bat 
  ::  No-USB, Wi-Fi only, adb/scrcpy static IP and static 5555 port connect
  :: v1p7 20260615 
  ::  Removed the requirement for the "no-console" vbs script
  ::  by injecting the necessary commands into a temporary file
  ::  This is the cleanest way I can think of to eliminate the console.
  :: v1p6 20260614
  ::  Called the vbs "no-console" script that comes with adb.
  ::  If the script isn't there, then it defaults to the old method.
  ::  The problem is getting completely rid of the scrcpy console isn't working.
  ::  These are the known scrcpy console-hiding methods:
  ::  (a) cmd /c start "" /min (minimizes the console)
  ::      The console is not hidden. It's just minimized.
  ::  (b) cmd start "" /B (background launch of detached console)
  ::      This detaches scrcpy from the batch console
  ::  (c) adb default VBS no-console wrapper (fully hidden window)
  ::      Default GUI-subsystem scrcpy launch (so no console is created)
  ::      CreateObject("Wscript.Shell").Run strCommand, 0, False
  ::  (d) Kleebauer ShowWindow() controller trick to hide the batch console
  ::      showwin.exe 0 SW_HIDE (Hides the batch console)
  ::  (e) Powershell ShowWindowAsync (similar idea to Herbert's ShowWindow()
  ::      Add-Type '[DllImport("user32.dll")] 
  ::      public static extern bool 
  ::      ShowWindowAsync(IntPtr hWnd, int nCmdShow);'
  ::  Here is the original scrcpy-noconsole.vbs that comes with adb
  ::  strCommand = "cmd /c scrcpy.exe"
  ::   For Each Arg In WScript.Arguments
  ::   strCommand = strCommand & " """ & replace(Arg, """", """""""""") & """"
  ::   Next
  ::   CreateObject("Wscript.Shell").Run strCommand, 0, false
  :: v1p5 20260613 Added query asking for the LAN IP address of the phone
  ::   Reordered comments to allow the current version to be obvious
  :: v1p4 20260612 minimized the scrcpy console (but it's still there)
  ::   using cmd /c start "" /min (minimizes the console only)
  ::   The only known choices are
  ::   (a) Minimized console-subsystem launch (cmd /c start "" /min)
  ::   (b) Background detached launch (start "" /B)
  ::   (c) Hidden GUI-subsystem VBS launcher (no console created)
  ::   (d) External ShowWindow() console-visibility controller (Kleebauer trick)
  ::   (e) PowerShell ShowWindowAsync console hider (similar to ShowWindow())
  :: v1p3 20260612 moved the pipe outside the FOR command for reliability
  :: v1p2 20260611 further reliability improvements added to v1p1
  ::   Use separate retry counters for pair/connect to avoid loop 
  ::   interference (ATTEMPTS_PAIR, ATTEMPTS_CONN)
  ::   Added fail-fast with clear error codes and user hints after retry 
  ::   exhaustion
  ::   Added a detection of the device id after initial connect 
  ::   (handles ephemeral adb ports like 192.168.1.4:54321)
  ::   Use DEVICE_ID for subsequent -s tcpip command (quoted) 
  ::   to avoid parsing issues with colons
  ::   Fallback device-id lookup when initial pattern match fails 
  ::   (robust parsing of "adb devices")
  ::   Consistent quoting of %ADB% and device identifiers to avoid 
  ::   CMD parsing errors
  :: v1p1 20260611 reliability improvements added to v1p0
  ::   Added better device lookup (skip header,ignore blanks,avoid false matches)
  ::   Added retry logic for adb pair & adb connect (for when phone not ready)
  ::   Improved polish (consistent quoting, stable scrcpy launch)
  :: v1p0 20260611 converted adbconnect.vbs to adbconnect.bat
  ::  Connects desktop & phone over adb & mirrors phone on the monitor
  ::  No USB cord is used in this process as it's all done over Wi-Fi
  ::  Should work even if either the PC and/or the phone is rebooted
  ::  The script will ask only for the minimum amount of data needed
  ::  Change the phone static IP address as needed to fit your LAN IP address
  @echo off
  setlocal enabledelayedexpansion
  :: For phones with static IP addresses, change the next line
