How can I block ALL calls on a rooted phone without an app?

Nowhere land..
I have a rooted phone, I posted this in the general section because I would think this would apply to all android phones.

My phone is a motorola bionic, but again, I felt I would have better luck posting this question in the general section.

I already know of apps for rooted and non rooted users alike.

I would rather freeze some system app or do some tweaking on my own.

This is what I want.

I do not want any incoming calls.

I do not want to be notified or have any knowledge of any missed calls.

I do not care if a proposed hack effects the outgoing calls.

I do not wish to share my reasoning for such advice other than I dont talk to people on the phone unless I initiate the call. :) I may share my reasoning this weekend on one of my blogs, it's too lengthy for a forum post. :)

So, how can I do this? I know it's possible. I just don't what system app to freeze.
 
Not sure how to do that anymore without losing data service with lte phone. I know with the D1 there's a way by going through the program menu but I wouldn't advise doing that in fear of messing up your phone.

Edit:

Well it does work but you have to disable LTE and you'll only have 3g data. I'm not sure if you would want that.

It's a little extreme, but you could turn off the phones radio.

No inbound or outbound phone, text, or data.
Data and Gmail (no push) will work on WiFi. Text does not.
Inbound calls are send direct to Voicemail.
When you turn the radio back on you will be notified of ALL texts, gmails, and voice mails.
You will NOT receive any missed calls in your recent list.

You have to go into the testing menu to turn off the radio.
Open the dialer, type *#*#4636#*#* as if you were dialing the number. Don't press send.
The Testing menu will open.
Select Phone Information.
Scroll to the bottom of the screen.
Press the toggle button "Turn off radio".
Press Home.

Just go back into the testing menu and toggle the radio button to turn the radio back on.

There is an app that does what I need, but its too new. I know it can be done. :)

By to too new I mean I dont trust it. :)

Would you consider an app with over a million downloads? Because if you're willing to route all calls to a voicemail you'll never check anyway, Call Control may serve your needs. The key is getting all the settings right.

Privacy mode = block all

Check the following:

Enable call control
Restart when phone boots
Pre ring muting
Hide blocked calls from call log
Send blocked calls to voicemail
Block private and unknown calls
Hide notification icon
Hide blocked calls/SMS notification icon

That's the only way I have found without losing other functionality beyond what you listed as being ok with.

It's all good if I do mess up. I know how to reflash it. :)

That's just it, I need the data end of it (With 4g).

Thanks for the suggestion. :)

Ok then.

I've only tried this for our Bionic, I'm not sure if this will work for any other phone.

Turn your phone to CDMA only through settings.
Then follow what Doit2it instructed by

Dialing *#*#4636#*#*
Go to Phone Info
Scroll down and you'll see a drop down menu under Set Preferred network type:
Choose EVDO Only.
Exit out by pressing the home button.

You should be able to access the internet through 3G but you won't be able to dial out, receive calls and I'm not sure about text.

Btw- Dang 3G is slower than I remembered. haha.

Yeah, I would try a seasoned app and even be willing to pay for it. :D What app do you speak of? It's called Call Control?

Yes. I just tried it with those settings and it worked quite well on my phone for your situation. Plus you can still call out and lose no data including lte functionality. The only thing I'm not sure about is whether incoming texts will be blocked since they are attached to a phone number as well. Didn't investigate that.

Ha ha ha! Yup, I noticed how slow 3g really is compared to 4g. If I knew how to reverse engineer an .apk I would just try to dig through it and find out what settings to toggle and or freeze to keep 4g. I don't text either. :)

Cool! Thank you so much! :D The text thing is not an issue, I had verizon block that. :)

You can still make emergency calls. I posted thus reply while my voice connection is off and I'm on 3g. Text does not work either.

See! Now you got me really curious to why the heck you would want no calls no text just data! I know you don't want to share it which is cool but darn you!!! haha:p

I never was one for texting, that's what skype or fring was for if I ever did.

I'm just rebuilding my life, I don't want to hear from anyone and don't want the knowledge someone tried calling.

I'll post it in a blog this weekend and come back to this thread and post a link to my post. :)

Thank you. :) If the app doesn't work I can live with 3g cuz I mostly listen to internet radio anyways and 3g has ample speed for that. I'll just reverse the settings when I need speed.
