[APP] Reset Wear Client - Switch phones without factory reset - Wear OS Software and Hacking General

Android Wear allows pairing to a new/second phone only after you perform factory reset of Android Wear: "You can switch which phone or tablet your watch is paired with, but you need to reset your watch to factory settings first. Then you can pair your watch to the new phone or tablet." Google Support
It's ok for most people but some just have more devices and want to switch them from time to time. Performing factory reset means compiling apps to aot, retransferring all apps the need to reconfigure all apps (Wear Mini Launcher, anyone?).
There used to be an app BeeLink but it stopped working and was removed.
There's actually way faster way how to set up connection with a new phone - in a minute. Just delete application data of "Google Play Services Wearable" app and reboot. All the 3rd party apps with their configurations, all watch faces with configurations, Google Fit data, and basically everything else will be kept.
Step by step
Wear is connected with phone A so turn off Bluetooth on this phone.
Execute following command on Wear (with ADB enabled - doesn't require root) or run attached app (root on watch required).
Code:
adb shell "pm clear com.google.android.gms && reboot"
Power on Bluetooth on phone B.
Depending whatever devices were paired previously, confirm pairing code or initiate new pairing using following command (thanks @matejdro) or also use the wear app for that
Code:
adb shell "am start -a android.bluetooth.adapter.action.REQUEST_DISCOVERABLE"
Finish setup, let it work for some time and restart both phone B and your watch to properly apply all changes. Done.
Attached apk is for installation on mobile phone (it contains and installs the actual Wear app). It's not on Play Store yet. Let's try it and get some feedback first.

Hi,
Thanks for making this for those of us who know nothing about adb. Unfortunately, I could not get this to work, but I'm certain the error is at my end. I downloaded and installed your apk, but I can't get it to open or find it in the app drawer. Excuse my ignorance. Could you please inform me as to how I can run the apk after installation? I downloaded it on to phone B, which does not have android wear installed, as per your instructions. However, I never got passed step 2 of your guide for the above mentioned reason.
Thank you kindly

Run the following command on your pc (with Wear connected and ADB enabled - this doesn't require root) or use my app for switching on-the-go (it requires root on Wear).

this App needs to be Sync'd to the watch so download it to Phone A, which is already paired.
wait until it syncs or manually sync Apps in Wear App on phone A.
when it's availalbe on your watch, then start this procedure.

---

hmm, just tried this (both ADB command and App installed on watch) with a new phone and I couldn't get it to pair. had to do the watch reset

---

Not working for me either. Will try the adb route when I can and report back

---

Finally a solution to my problem.
When i flash a new ROM i have to pair my moto 360 again... And to do this i allways do a reset on my watch...
Next time i will try it and give a feedback.

---

Not working on moto 360 5.0.2, rooted?

---

I was trying to figure out this one, but could not found proper app to clear. I cleared GMS, Wear launcher, settings etc. and nothing helped. In the end I found this solution which is even better IMO:
Code:
adb shell am start -a android.bluetooth.adapter.action.REQUEST_DISCOVERABLE
After executing above code via ADB, dialog will pop up on wear asking if you want to make watch discoverable. Then you can find and pair it to any phone.

Hi, my SW3 was connected to my Mi 4, setup done and working fine. I used Titanium Backup to backup Android Wear and all the watch faces apps.
After I flashed a new custom ROM, used Titanium Backup to restore Android Wear and watch face apps, and also Bluetooth connections on my Mi 4. When SW 3 is connected to my computer, in Adb, it says unauthorised.
Since it is unauthorized, I can't run the ADB command.
Any suggestions?

---

I don't think there is anything you can do at this point. You should have authorized your PC when you still had working watch connection.

---

any plans to update it

Using Minimal ADB, I had to run as admin to make this work, but then it worked perfectly. Thanks very much!

---

nothing. doesn't work with 5.1.1 g watch rooted, the app gives me black screen (dismissable with swipe)

---

Just using app from OP is apparently not enough anymore on 5.1.1.
I just made tutorial on reddit on how to reset 5.1.1 watch: https://www.reddit.com/r/AndroidWear/comments/3c4qf8/tip_how_to_switch_phones_without_hard_reset/

---

I updated the Wear app (v0.2) with support for requesting Bluetooth discoverable mode as well.

---

Did you guys see this: https://developer.android.com/training/wearables/apps/bt-debugging.html

---

Yes! I'm so glad something like this has been developed! Worst part about switching ROMs is resetting android wear now. Thanks so much!

---

Performed the clean in the watch.
It works, and is possible to link the watch with another phone without perform a data wipe.
Then only problem that I've encontered is that the installed watchfaces aren't visible in the Android wear app (in the phone), and I can't set from the phone or hide some.
Thanks
EDIT: Sometimes, due to the watchfaces issue, Android wear app UI generates a FC

Did you also try reseting app data of both Android Wear and Google Play on the phone (& restart)?
