How To: “KnockOn” Your HTC One (Double-Tap Screen to Wake)

Thank you!

I installed it on Google Edition and some of the functions work great and some do not. For example clicking on the logo to wake the device.

So that feature doesn't work at all, or it kind-of works?

Are you double tapping the logo?
Also, be sure you are tapping the area right above the HTC. It can be tricky, but you'll get the hang of it.

Great !
Is it possible to do this on an HTC One that was converted to a GPE using the other tutorial here ? (RUU)

If yes, then how ?
Great set of tutorials you have here. THanks a lot.

Yup! If you are on the latest version of the GPE ROM (Android 4.4.2) and you have a GSM/LTE HTC One you can flash this bulletproof kernel. If you're on a lower Android version let me know and I'll find the one right for you.

Yes I am on 4.2.2. Thanks for the link. And also I have the pre-rooted version.

So I tried this, according to your tutorial, but I think i dont have the recovery option. When I select Recovery in bootloader mode, it takes me to a picture of an android robot and then later a red exclamation !

I have to long press the power button to shut down and reboot.

I think I have to flash a recovery. But I wanted to confirm if its possible to do that with RUU converted phones ? It being pre-rooted and all. And will there be any further issues ?

Also, If there are any future OTA updates, will i be able to install them (being rooted, custom recovery and all )

Thanks so much for all ur help.I am very new to all this.

If you were to flash a custom recovery you would lose the ability to flash OTA's downloaded from your carrier. You could flash them from a custom recovery though, there are always XDA threads with the newest flashable OTA zips.

To flash a recovery look at this guide and the instructions will be under the Install TWRP section. Just be sure to have an unlocked bootloader.

does it work on htc one max?

This wouldn't work on the One Max. You can use Knockr to get the same effect without having to flash a kernel.

does it work on htc one dual sim ?

Does anyone know how this mod impacts battery life? I'm interested in Knock On but was wondering if the polling of the screen whilst off would impact the battery significantly?

You may notice a slight dip in battery life, but if you enable pocket protection you should minimize the impact.

Just work on HTC?

Yup. This will only work on the HTC One M7.

i have followed the instructions above but now my phone just keeps showing the htc start up screen and vibrating over and over...what do I do now?

It sounds like the kernel flash had a problem. Reboot into TWRP and restart the prcoess and let me know if that fixes it.

Will this work with an HTC One M7 that has Sense 6?

Yes, but if you want to get the same wake gestures as the M8 I would use the ElementalX kernel along with Sense 6 Toolbox. Those work best with Sense 6 and the toolbox will let you customize the gestures to do whatever you want.

How is the battery life?

It has actually increased my battery life.

can i use it on HTC One XL ?? I am using CM 11 4.4.3 with CM kernel. I need double tap to wake and sleep or slide to sleep and wake ...

Nope, but you can use this kernel instead.

Another great tutorial Andrew!!! This was a function I absolutely wanted on my HTC One!!! Super simple to install and it works PERFECTLY!!!

Thanks again!!
Maggie

Any chance this kernel will be made available for the Verizon HTC One (M7)?

You could use Elemental X. Its fully compatible with the Verizon M7.

Hi,

I know nothing about smart phones; my questions may sound stupid. But I really do not have anyone around me for help, so I come here. My phone is still 4.1.2 I just bought this m7. Then what I need to do is to update my software and download this bulletproof 4.4.2?

And if I do not root, I cannot do anything?
thanks

You would need to run the software updates to get up to the newest version of Sense and then root. You can't apply any of these features without root.

thank you. Maybe I'd better wait and see if htc will offically release any update to solve these problems.

how to flash HTC Butterfly S ok men !!!!!!

Is your device rooted? If so, what ROM/Android version is it running?

Hi, I know nothing about root, hope you don't mind me asking silly questions. My HTC one m7 is 4.4.2 with sense 6.0, and I just want to use the feature knock on or swipe on. What are the steps that i should do?

Will all my existing data be lost after rooting? Thanks a lot!

The only way to add this feature is through rooting your device. You will lose all your data, but you could use my other ADB guide to backup all your app data.

Thanks for your reply! How to root it and install the feature of knock on? Do you have any direct link of guide from you?

And the backup guide as well? Thanks heaps!!

Will this work if I have HTC Sense 6.0 Android 4.4.3? There seems to be not any HTC Sense 6.0 Android 4.4.3 bulletproof downloads.

Check out ElementalX.

I installed it and it works but it caused some strange pixelization of the screen which i didn't have before. Anyone else have this problem? I have the stock sense and have ARHD 81. Can bulletproof be uninstalled separately? Thanks.

You can replace the kernel. Try ElementalX. It should fix your pixel problem.

when i open my camera phone restarts and there are some sort of lines appearing on the screen i have sense 6 and android 4.4.3 what do i do ?reply soon thanks

will elementalx help
?

You should give elementalX a try. It has the newest kernel patches so it should fix your issues.

Hey I am new to all of this. I want to activate the double tap feature.

I have HTC one M7 (4.4.3 version) . Since you said ElementalX is better. I wanted to know how to do all this. I mean should I do recovery and all or directly install ElementalX?.

If I have to do recovery can you please guide me on that. And will this recovery harm my phone or void any warranty?
Thank you in advance

1. This does void your warranty.
2. You can use the HTC One root guide here to install TWRP recovery and then flash ElementalX through it.

will it work on htc one GPE 4.4.4????

It will work with the ElementalX kernel.

Hi, I need some help.

Was stuck on step 2, I hold "power" and "volume down", made it to the bootloader screen, after i choose "recovery" and pressed the "power", it goes to black screen and a while later an exclamation mark appear, and I have to restart it by holding "power"

was using 4.4.3 and downloaded ElementalX-m7 from http://forum.xda-developers.com/showthread.php?t=2249774

That means you need to flash TWRP recovery again.

Will this work on HTC One mini 2 ? If not, then do you know a kernel which will ?

THanks

Here you go

Thank you very much , it worked :)

merhaba htc m7 kullaniyorum android 5.0.2 ye knock lock yapabiliyor muyuz

Sorry, not quire sure what you are asking. Are you trying to see if this is compatible with Android 5.0.2?

Is this working with android 5.0.2?

Android 5.0.2 on which ROM?

7.19.401.2

Use ElementalX kernel instead.

Ok, done ! Thanks for help :)

hello Andrew, im using android 5.0.2 on viper rom 8.

Queston #1: should i use elemental X too? what is elemental X's kernel have that bulletproof kernel does not?

Question #2: should i do a backup before flashing the kernel? would it wipe everything off? Because what i understand from your article is we can just flash the kernel right away after downloading it, no backups

They do a lot of the same things, but elementalX is updated more often. You can do a backup before flashing, but flashing a new kernel does not wipe anything.

okay, i have another question now. i have installed the elementalX kernel succesfully. how do i tweak with the kernel settings? i want to disable some mods (sweep2wake) logo2wake is good enough for me

Reflash the kernel and only check the features you want.

Thanks for the swift response, Andrew!!

I did find and install the proper elementalx, it didn't do Swype to wake, nor double tap to wake

Which one did you install? Did you select those options during the AROMA installer?

Hey!

I have installed the Elemental X for the 5.1 version on my HTC One M7(Vodafone NL), after it was rooted succesfully and after it was installed my screen just turns black and the phone wont start again,,,,

I tried restarting and entering recovery mode but nothing works, I can only restart, see the HTC logo and then the screen turns black again and stays stuck.

Does anyone face a similar issue, I am tripping over this, cant use my phone and any insight would be greatly appreciated.

When you hold down the volume down and power buttons does it take you to the bootloader menu?

my htc one m7 .. after i install the zip file my phone never start again just htc logo then get on to recovery whay?

What version of Android/Sense was your M7 running prior to the zip flash?

sense v. 6

Check out the ElementalX kernel XDA page and download the kernel that is right for your Sense/Android version. That should fix all your problems.

i installed elementalx and everything was success , still tap feature is not workin, Android 5.0.2 ver. 7.17.402.5

Did you select that option in the AROMA installer?

does this work on the htc one mini with android 5.0.2 and a candy 5 room

No this won't work on a mini, but check out its thread on XDA for more options.

Plz help my htc one isn't starting it's again again going into recovery mode
