Knock code grayed out, but code changed. Cant change it and phone wont lock - G3 Q&A, Help & Troubleshooting

HELP!!!
This is a really weird problem with my non-rooted D850 on an MVNO (H20 Wireless). I have had the phone for several months and other that a battery issue, I'm super happy with it.
I had been using the knock code to lock the phone and my home as a safe place. Never had a problem with the knock code.
Two nights ago, in an attempt to appease a suspicious wife, I decided to change it to a pattern so she can get in, then I got a pair and decided to change it back to the old knock code. I then noticed that the knock, and swipe where grayed out and so did the research and cleared the credentials to bring the knock code option back. Now the knock code does not match and I can't change it to anything else.
When I reboot the phone the knock code request comes up. I start to do the knock code and it turns off the screen at the second "knock". I double tap toward the top of the screen to avoid the knock code area, the screen turns on and it's asking for the knock code, wich doesn't match, but I start the one I knew again and it turns the screen off again and the 2nd knock. After five times the phone asks for the back up pin and I'm in, and the phone immediately asks to change the lock screen. I change the screen lock it to a pattern as the knock and swipe are grayed out again.
I receive confirmation of the lock screen has been changed, but NOPE!!! NOT CHANGED!!!
It's still asking for the knock code, that doesn't match, at reboot, or when I try to change the lock screen. To add insult to injury the phone won't lock, even if I leave it sit for an hour (time out is 2 min and I'm not at my safe place)
Any thoughts other than a factory reset?

Not having any luck with research. I would love someone's input.

Beuller? Beuller? Beuller?

Now I find that I can't reset my phone b/c of the knock code that doesn't match

Factory Reset
You could try powering off the phone, holding the volume down and power button. When the LG logo appears, quickly release the power and volume button and after that hold them again, you will see a white screen with an option to reset the phone. Don´t know if this works with the knock-code, let me know!

I ended up doing a factory reset a couple weeks ago. I couldn't find ANY support information about this. The phone had the knock code locked in, and since it "magically" changed (or fat-fingered when trying to change originally) it rejected the only knock code I ever used. The LG volume/power reset is difficult for me (as are screenshots) to perform as I have fairly large hands and the buttons are right next to eachother.
Either-way, i ended up resetting the phone and now only use a PIN or pattern to lock it. Pitty many apps seem to not like the knock code as a secure locking method.

hi every one,I have one brand new g2 Tmobile, just got from ebay,when i insert unlock code it say that unlock code success,please reboot,after reboot it require unlock code again,i tried 3 times but the same thing,any one can help me??thanks
Don't use an unlock code, they've caused a lot of problems.
Instead, if you root your phone and then use this guide you can get SIM unlock for free - http://forum.xda-developers.com/showthread.php?t=855764
Hello, I just bought the HTC desire Z and have put the draw pattern lock code on, and have forgotten the pattern. I have had it just 4 days so any lost data is not a big deal. I have tryed the volume down power button hardset way. but it always just sarts the phone and brings me back to the draw pattern lock. If anybody has had to hard reset their phone, any ifno would help. Otherwise my phone is going away for 4-6 weeks.

what happens when you goto forgot pattern?
I can't get into anything. The phone starts up and then you can slide down on the screen then the 9 dots come up for the draw pattern. thats all i co do
try to enter your pattern 5 times, when the "wait 30 seconds" prompt comes up hit "ok", then there will be a "forgot pattern" button in the lower left

[Q] Can't get past 'set-up' wizard screen

Phone arrive in mail yesterday. Charged phone fully. Turned phone on. Lots of voice activations on the set-up wizard screen. I try to pick a language from the drop-down screen and it just highlights it with green dashed lines and the voice activation says 'english'. That's it. I try to hit the next arrow for the next step and it keeps telling me the time. I mean I'm no expert by any means but I'm also no rookie when it comes to turning a phone on for the first time. This is really weird. I can't get past this screen. Tried fully shutdown and start back up. Same thing. Mind you I haven't put a sim card in yet but I didn't think that would matter as I was going to use wifi to set it up anyways. I can't even turn the phone off by touching on screen either. I have to long press the power button to turn it off as the touch screen doesn't seem to work. Anyone have issues with this? It's very disheartening coming straight out of the box...

I got past the screen but I had to 'double-tap' (and by double tap i mean like 4-5 taps sometimes) the next arrow. I have to do this at every screen until it gets to the log into gmail screen. I try to type my email in by double tapping each letter but this doesn't work. Now I have no idea what to do.
I had the same thing happen to me yesterday and figured it out.
If you have not figured it out let me know I can help.
mine arrived same problem

I'm having this same issue as you. Mine just arrived today. It seems likely they put a recent image on these that may have something missing off broken on it. The models before them seem to not have this problem. Worst is you can really fix it or get past it since its the initial setup. What to do now? Send it back?

TalkBack may be enabled. If this setting is enabled, there will be voice prompts to every action made. Also the touch screen may behave differently and appear to be defective. Instead of one tap to open an item it will require tapping once to highlight then double tap to open. Also when swiping it may require using two fingers instead of one. To disable go to Apps/Settings/Accessibility/Talkback - turn off.

Thanks! This worked. I found someone else online who had the same issue and that's exactly what happened to him. I just used 2 fingers to click through the setup wizard and then finally was able to go into settings and turn TalkBack off. This was very annoying right out of the package. Hope this helps someone else.
Could any of you please kindly send me a private message with the model, serial number, and if purchased in the USA? We are trying determine which units have been distributed with TalkBack feature enabled.
Thank you,

I had someone that had this happen at the Intel pre-Google IO event Wednesday night. If you don't want to go through the full setup -
1). Turn the phone off
2). Hold volume up + Power
3). Use the volume down button to highlight recovery
4). Press power button to select, it'll show an erroring Android screen now
5). Press volume up + power again (might take a few times before the recovery menu is available
6). Wipe user data and reset. It'll take a few minutes but it'll save you from having to deal with talkback
Thanks so much for this thread. Just got mine and am in Nicaragua and have no way to send it back to Amazon and was gonna flip the **** out.

Same issue on mine. Purchased via Amazon. PM you the info...
Same issue- purchased from Amazon
I had the same issue when I received my phone this morning. I couldn't get it to work even after following the instructions to power it off and then power on + volume up. I am returning it to Amazon for a replacement. If I have the same issue with the replacement, I'll just return it. There's no way I'm paying $200 for a brand new phone to have it not even work upon taking it out of the box.
I just received my telephone today... After spending 20 minutes to pass the wizard guide (as i had to tap over 10 times to pass a single step), I cant even unlock my screen. Im from Bulgaria, there is no way I will send back the phone to Amazon. Its just not financially possible for me. I dont know what to do. A brand new phone...
i just bought an asus zenfone 2 from amazon and the same talkback is happening.
ready to shove phone where the sun dont shine

Push power button when you see the android with eroor under it and press up volume, you might need to dothis a couple of time but be aware that if you do it too fast you can go to recovery then jump back out just as quickly.
Holding power for more than 8 seconds will result in a reset.
Hi, Just bought the Asus ZenFone 2 , I cant pass the Welcome screen its talk back feature is on Pls Help. Thanks
This is 4/30/16. I just got my screen replaced on my ASUS ZenPad 8 inch 580. Same problem happened with Talkback to me. I followed the instuctions from the guy who said tap twice on the buttons. I had to sometimes do this many times, but I got through to the tablet settings to turn Talkback off even before settig up Google and other apps, I just connected to my wifi, then went next until the home screen could be opened, then settings symbol, then accessibility, then turned off Talkback. Boy was I happy. Maybe I got an old LCD and screen? Dont know why it happened so much later than you people in 2015. from:[email protected]

[Q] Touchscreen only works in power menu?

Hello,
I just got a nexus 7 2013 that had a busted screen. It still showed data between the huge shatter, and didn't respond to my attempts to unlock it by swiping. I assumed it was just a bad screen and bought a replacement and installed it today.
The display worked, but the touchscreen didn't seem to be responding to me trying to swipe to unlock. I eventually figured out that although I couldn't unlock it, the dialogue menus from long pressing the power button did work! Well, some, anyway. I can change sound modes, airplane mode, and access the power off dialogue, but am only able to select cancel from the two options, though ok is not grayed out. I can also click anywhere outside the dialogue and it will back out of it, leading me to assume that the screen's hardware is intact and functioning.
I then hard reset it via stock recovery and am now at the welcome screen prompting a language selection with the big right arrow, unable to press it but still able to interact with the power off and cancel options of the power menu.
Recovery says its running KOT49H.
I've used NRT to reflash the same build from a stock download, and I'm still stuck at the same spot.
What the heck can I do?

I would assume that the new digitizer is still bad. There are lots of them on sale on Ebay where the seller would assure the merchandise has been "tested" before shipping. In reality, they might not be. If you happen to have one with spotty functionality, there's nothing you can do with the software to cure it. It would not respond in some areas, period. If you only replace the digitizer instead of the whole LCD/touchscreen assembly, chances are you have a partially bad one. I've never come across one good one myself.

Any way to manually lock the phone?

How can I lock my phone if I decide to lock it, while the self-locking stuff is disabled?
I prefer to keep my phone unlocked. So I put a 30 minute timer to prevent the self-locking, and disable the option of "immediately lock when power button is pressed."
But if I get stopped by the police I want to lock the phone immediately. Any way to do that? Currently I'd have to hold the power button, and select restart or power off, then confirm it, and that can be awkward if you are running away.
Run faster than the police.

I never tested it that way to be certain. But I was using "Screen Off and Lock" on my last phone, because the power button was getting flaky. So I used the SO&L shortcut as a substitute power button to turn the phone off. Then I'd wake it up with the Home button.
I believe SO&L would lock it immediately, even if normally it would not lock right away if I had used the power button.
Maybe give it a shot?

If we answer this, could we be charged with assisting a felon?
Just kidding about anything nefarious, hope it brought some smiles?
But the point remains. If I want to lock the phone occasionally, but generally keep the phone unlocked, I don't see a way to do this on the phone without resorting to aftermarket apps?
I think vanilla Lollipop android has the option to lock the screen when you are on safe tether, but that's disabled for me on the G4.
If you are worried about the police searching your phone have it auto lock when you push the power button and have it lock on a short timeout.

help, locked out of oneplus 3

my oneplus 3 (rooted) is not accepting my swipe pattern and does not give me the option to enter a pin code after a forgotten swipe pattern. i called oneplus but the person i spoke to said the only option was to wipe the phone. she would not allow me to talk directly to anyone with any technical expertise.
when i power on the phone everything seems normal until i get to the swipe pattern screen. first ,the bootloader screen (i think, the screen where you either press the start button to start the phone, or use the volume buttons to select options like poweroff/restart/recovery etc) shows up and then the oneplus logo comes up with the 'powered by android' at the bottom. then it shows the two white dots orbiting the red circle and then the screen to enter the swipe pattern appears with 'to start android, draw your pattern' at the top. i have made a few failed attempts, but it is now counting down, saying you have 6 attempts before the phone is wiped.
about two weeks ago i began having an issue that occurred maybe 2 or 3 times since. i would pull my phone out of my pocket and it would be powered off. after i turned it on, the initial swipe pattern would not be accepted, but the second swipe was always accepted.
i have tried entering recovery mode (teamwin), but the swipe pattern fails here also.
is there any way to get the phone started without losing my data?

Don't think you can do anything. Haven't encountered this what did you do with your phone? Are you on the latest TWRP? Latest OOS?

i had not changed anything on the phone recently. the swipe pattern has been the same since i got the phone over 2 years ago. i believe i was on the latest twrp, and i had a notification for about a week or two that there was an update available, but did not get around to downloading and installing it yet.
