I've locked myself out & need to unlock it. I have turned on TalkBack & I need to turn it off.

There are a lot of methods to bypass the Google FRP lock. The easiest method to bypass the Google FRP is Google TalkBack method in which you will have to enable Talkback and after enabling Talkback, use the L gesture on your screen in which you will see the Talkback setting, scroll down and click on Help & Feedback, will see the help menu and there will be a youtube video on your screen, play that video and select "Play on YouTube App" and after opening YouTube app, go to settings and select "Terms & Policies" , after opening the T&C menu , select a text and search it on Google, and after opening the Google app search for Google FRP unlock app and you are good to go

try turning up VR-501. which ever way it is turned now turn it the other way to max and see if that works.If not turn it to max the other way.

one turn off echo and talkback will turn off. or disconnect the wire goin to the transistor off the echo board that turns on the talkback.

Open the case on your radio. Solder a 100 ohm resistor between the pa jack and ext speaker jack. You can add a switch if you like to turn it on and off. The lower the resistance, the louder the talkback.

timspur, hi. First off, using the talkback with a tuned Galaxy will give you problems, so you need to use a good noise cancelling mic like a RK 56, or Astatic 636. If your running an amp, that will only amplify the problem. Here is a mod if your comfortable working on your radio, to tone down the TB volume.
******
Talkback can become distorted if these radios have been "peaked," and there is no cure because the talkback just amplifies what goes to the RF section. Try adding a 470k ohm resistor from junction of C155/R207 to the junction of C187/R235 on the solder side of the board. This will also give you clean talkback on SSB and FM. Try different values of resistance to get the amount of volume you want. The less the resistance the louder the talkback will be.**
Hope this was what your looking for,, I know for a fact that the Astatic mics do help tone it down.
Let us know,,, Mechanic
