[Android Software/Hacking General [Developers Only]] GalaxyA325G:
Is there an updated XDA tutorial yet on setting up adb COMPLETELY wirelessly as of Android 11?

Why do I ask?

Using adb is a critical developer/hacking/user tool

As of Android 11, adb has been fundamentally changed for Wi-Fi

As of Android 12, adb was further improved for Wi-Fi

The existing XDA Developers' tutorial doesn't contain that info

I figured it out on my own (see below)...

(Which meant a LOT of new questions popped up that had to be solved that could have been answered in a tutorial)

Unfortunately, almost everything out there that I can find about adb is (wrong / inaccurate / incomplete [choose one]) in terms of how to set up a wi-fi connection as of Android 11 & 12.

The problem is there are important questions to be solved that are MISSING from that old tutorial :(

(These problems revolve around connection completely from the PC side only)

Where I would think EVERYONE would have the SAME questions as I do about the new setup

(And for which an updated XDA Developers' adb tutorial would be very useful!)

Mostly these new Android 11+ Developer options Wireless debugging features eliminate the USB cable.

But that then instantly brings up the non-intuitively fundamental question of ESTABLISHING the connection

solely

from the PC...

(which - let's never forget - is how the older, well documented USB-cable-first-

then

-Wi-FI adb connection had always been done)​

Hence my question of:

Is there an updated XDA tutorial yet on setting up adb COMPLETELY wirelessly as of Android 11+ & 12+?

DETAILS:

Spoiler content hidden.

Whew! I said what "should" be in a tutorial so others don't have to figure all of that out on their own just to set up adb completely wirelessly (without first establishing a USB connection on the PC).

I figured it all out, of course, but that XDA Developers writeup didn't help (in fact it hurts)... because it contained completely outdated information (which is why I wrote that long paragraph above, to summarize what's completely missing).

Here's what needs to be done on the phone:

Enable Wi-Fi (mine is set up to NOT auto-reconnect, for privacy)

Establish a connection over Wi-Fi to an SSID on your LAN

Enable Developer options:Wireless debugging (Android 11+)

Enable Developer options:Wireless debugging Tile (Android 12+)

Enable random MAC address per SSID (Android 11) or per connection (Android 12+)

Enable the (so-called) static IP address of the phone

Physically eyeball the random Wireless debugging port assignment (&/or random port + random PIN)

Note all the questions are related to the fact everyone wants to eliminate that last step above!

On the PC:

Simply assure yourself that the phone is on the LAN (e.g., ping 192.168.0.2) (duh)

Remember - it's using a RANDOM MAC address so the router has to be configured for that

Then connect from the PC adb to the phone completely over Wi-Fi (encrypted or not)

Remember - there's no initial establishment via USB - which means you need to know random ports!

adb connect 192.168.0.2:12345 (or) adb pair 192.168.0.2:12345 123456

Remember - everyone's goal is to obtain those random ports 100% from the PC side of things

You may have to accept an encryption dialog on your phone if this is the first time using that PC

At this point, adb over Wi-Fi works the same as adb has always worked (over USB first, then over Wi-Fi).

Until, of course, Android randomly resets the port assignment - which it does frequently!

Then you're back to having to look at the phone for the random port assignment

Notice that most of the issues people are having (see reference list below) are related to the fact that the random port assignement, as far as we know, can ONLY be obtained from a visual inspection of the Android phone - but also notice that nobody used to need to do that in the olden days (when we connected via USB cable first!).

My observation is nobody wants to do that visual inspection of the phone every time, all day, every day, whenever Android re-randomizes the MAC address (which, for me, happens frequently but my phone is set up specifically for Wi-FI privacy).

In summary, this thread asks if there is an XDA Developers' writeup for connecting adb on the PC completely wirelessly to Android 11 and Android 12 and up.

The REASON I believe that XDA Developers' updated adb tutorial is needed by hackers/developers/users is:

a. The way adb works over Wi-Fi is COMPLETELY DIFFERENT as of Android 11 (this is why finding an updated tutorial is needed!)

b. I had to figure all this out on my own, so that means everyone else does too (unless I missed the XDA Developers' tutorial), and,

c. There are still a ton of open unanswered questions that everyone also has.

REFERENCES: (in no specific order, these are attempts to make it work the way everyone wants it to work!)

(PSA) Using the new Android 12 TILE for 'Developer options' 'Wireless debugging' to establish adb connection over Wi-Fi without USB

What's the difference between Windows/Android adb "connect" versus adb "pair" when mirroring Android 12 over Wi-Fi onto a Windows PC?

Android 12 Developer options adb "Wireless debugging" option keeps turning off

[adb,scrcpy,vysor] What ports does Android 12 randomly set when Wi-Fi connecting via Wireless debugging adb "pair" or "connect" commands?

[adb] What is the adb syntax to connect wirelessly to Android by unique serial number (instead of by Wi-Fi LAN IP address & random port assignment)?

Note that none of those threads would be needed if we could have found a comprehensive tutorial that was updated to Android 11 and 12 new connect-adb-over-Wi-Fi-without-USB functionality that answers those basic obvious questions to ask. (See illustrative screenshots below).

Is an updated XDA Developers' writeup extant for connecting adb on the PC

completely wirelessly

to Android?
