[Q] ¿How can I disable the searching for a mobile signal?

I got a new Samsung Galaxy Tab from Verizon, and I will be out of the United States for a very long time, I am going to Mexico, so I don't think I will have signal over there and my galaxy tab will keep searching for a mobile signal, and that means that my battery will finish really fast, because it will keep searching and searching and searching. I was wondering how I would be able to disable the search of the signal so I don't run out of battery really fast.
Thanks in advance!

Hold the power button down which brings up a menu to deactivate "data network mode"

Already did, and it stills keep searching for a mobile signal :S

try
settings
Wireless and network
mobile networks
uncheck all

Switch on airplane mode. then enable wireless networking. no signal hunt.
there is also a radio disable mode from phone pad *#*#4636#*#* I think. then turn off radio. same result as airplane mode with wireless switched on so first one easier.
hope that helps.

Here is a Summary of what I've been doing to try to disable the mobile signal, but not success, also here are some pictures of what is happening so you can understand me better. Here are the pics and captions: iamunicorn.com/GalaxyTab
Thanks in advance!

read my earlier post - switch on airplane mode, then enable wireless networking!!!
or alternatively, try searching the forum - its been addressed before.

Thank you! That works, but is not the best way or the way I am looking for, thanks anyways!

ok - if yu dont like that - try the other way. *#*#4636#*#* from phone keypad and turn of radio. same result!

How is it not the best way if it's the only way to do it? Really, it's a toggle switch, get a widget. How can it be any easier? That's like saying the volume rocker isn't the best way of changing the system sound.

What I meant is that there should be a Disable button, like any other cellphone... but thanks anyways I will use it like that for now.

are you kidding?

Of course you will have signal. It is not like you are going to Venezuela or something......... however roaming charges will apply
U$800 for a UMTS galaxy tab? f**k no!

figured it out

The Tab is just a cellphone I think, so an dedicated button to "disable" the signal is not a really good thing for samsung design team.

[FIX] Fix 50% Time Without Signal Bug

I found this while searching on google. I take no credit for this, but am posting it here so that you can use it too.
Basically it enables airplane mode and disables it at boot. It doesn't add any time to boot, because it coincides with the Media Scanning.
All you do is install it and forget about it.
Anyway, heres the link:

I actually had this installed for a couple weeks now. Phone boots and then goes into airplane mode. I did love the one time where my phone booted up, I got a phone call right and forgot about the airplane mode and it kicked me off the call!

It won't download to my phone and I'm stuck at work. Can anybody upload it here or post a drop box link for me? Thanks!
Edit: Forgot I can use Astro for the download.

Mike, what do you think of this explanation and fix? It is interesting to read there why this happens, if nothing else. I look forward to your ROM fix tonight!

I actually have 2 tasker events setup that takes care of this nearly transparently. On device shutdown tasker sets airplane mode and clears it on boot.
I just have to do it manually if I get some kind of random reboot or sleep/charge death.

ok and what is your percentage ?

I only realized this was an issue sometime last week and when I checked it was 50%.
Toggle airplane mode and within 10 mins it dropped to 38% and then went down to 17% a few hours later. But since then everytime I unplug or reboot I toggle airplane mode and most days it's at 0% ~ 5%

If I catch it right away it will go down to 0 by days end. If not and I catch it later it varies.

thanks for the link! i'm just curious though, is there any reason why this signal bug hasn't been addressed at the ROM level? from my brief searching it seems like it occurs on most devices.

TIP - Gain 8% more battery

Hi,
You may already know this tip but since I did some tests and measurements I thought that it's a good idea to share it.
I found that if you have the Airplane mode (flight mode) always on then A500 consumes about 8% less battery. Right now I am not in position to publish more details about why this is happening, since I am still researching it, but it works. It has to do with an application that periodically checks for 3G signal (Yes in A500).
Now most of you will think that WiFi or Bluetooth don't work with flight mode on. This is not true, they work as expected.
I have developed a free widget named TaToggles which is very helpful if you want to toggle WiFi, Bluetooth, Airplane etc. Read more about it here http://www.chdcomputers.gr/en/mnu-applications-en/mnu-applications-android-en/mnu-app-android-tatoggles-en
Hope this is useful to someone...
Thank you,
Christos

Thanks for the tip, I'll give it a try. Though, I hope that Bluetooth works , since it doesn't works while I'm on airplane mode on my Xperia.

This is an old tip, already discussed like a year ago here. I personally just use Acer Iconia Battery Saver on Android Market ( https://market.android.com/details?...RlcnBoYXplLkFjZXJJY29uaWFQaG9uZURpc2FibGVyIl0. ) to disable the 3G service altogether, no need to mess with airplane mode or manually toggling services on or off.

Same effect can be achieved by inserting "ro.carrier=wifi-only" (without quotes) into build.prop, which one can find at /system.
With best regards, maris

WiFi and Bluetooth work when flight mode is on???

Click to expand...
Click to collapse
In Samsung Galaxy Tab 10.1 and A500 yes they do. I don't know why this is happening but I suspect that it is because flight mode turns off the 3G radio and not all the radio. I am researching it and when I 'll have more I 'll post.
Note: If you have enabled wifi while you are enabling flight mode then it turns the wifi off but you can enabled it again without disabling the flight mode...

Yes. When you first turn airplane mode on, it shuts down all connections. Just toggle wifi, or Bluetooth back on, and it will stay in airplane mode. As a previous poster mentioned, it's old news, but apparently not old to everyone?

[GUIDE]Jelly Bean on 8013

I have put this all together on the uk release and put it out as a rom here:
http://forum.xda-developers.com/showthread.php?p=34971303#post34971303
So here is a thread to talk about getting the German release of Jelly Bean on the 8013 and the 8010
I cross referenced the way that pimpmaneaton did his redemption rom, being able to work on the 8013 and 8000 with the aroma installer, checked what was different between the two for ICS.
With the build.prop, it was mostly just some changes to from 8000 to 8013 in the naming of things, but there were also a couple things coded out to get it better on the 8013
We have been looking into the dialer commands to see if any will disable the radio, more on post 11 for that testing.
I have had success with no reboots as well as removing the pesky no signal icon. I have included a flashable zip file that will take care of the build.prop, delete the files we know are not needed, disable the telephone by replacing the framework-res, adding in darkman-rs circle 1% battery mod, removing the null signal and airplane mode icons by replacing the systemui.apk
Step one: Download a jelly bean rom
I have been using darkman_rs version of the JB since it is stock and works nicely, also he has a lot of other nice stuff for it like a circle battery mod I like, and the telephony disabler.
Here is a link to his rom http://forum.xda-developers.com/showthread.php?t=1909950
***
Flash rom, clear cache/dalvik
Reboot, login/setup/etc until you reach a fully installed state.
Then reboot to recovery and install the fix zip.
Set cpu to ondemand

fix zip for 8013:
https://www.dropbox.com/s/xkb3spitb5vhlas/Complete_jb80xx_v2.zip
fix zip for 8010:
http://db.tt/tNMC0ZAv
The only difference between the two is the device name in the build.prop
-------------------------------------------------
Other fun stuff:
Adding in the 4 way reboot
I got this from Team Unions ROM here http://forum.xda-developers.com/showthread.php?t=1995700
It is a great rom and all the stuff here should work for that rom as well
https://www.dropbox.com/s/v97fqjyuvjkx7f2/reboot2.zip
there are a lot of nice tweaks from pimp my rom
here http://www.xda-developers.com/android/pimp-my-rom-install-tweaks-on-any-android-device/
Set your governor to ondemand has gotten a lot of good reports for stopping the reboots. This can be done with several tools from the market, I use rom toolbox pro, others use setcpu.
This was posted by darksabre_x
Here's SetCPU. It's been released free for XDA members. Donate when you are able.

Super cool!!
I found this, some more information on the Pegasusq Governor
http://forum.xda-developers.com/showpost.php?p=24233103&postcount=3
I removed the non flashable zips because a lot of people were getting confused, all the same stuff is in the fix zips above and will be easier to update if need be.
If there are any more things, add them, lets see if we can get this up and running perfectly before samsung does!
Thanks to everyone here for working together to get this running on the 8013!

what do you think is causes the reboots?

In my experiences as well as what others have had, it only reboots when it is idle, so it would be an issue with the sleep mode of something, maybe when it tries to go to sleep, something tries to tell the radios to do something different and it doesn't like it to it reboots.
I am going to try getting my csc changed to germanys to see what that does.

Sounds like a Dormancy thing, how could one get rid of that?
EDIT: How come airplane mode doesn't help, and the shutdown while charging? I mean I can keep my screen on all day and while its charging but won't that damage it

Yes, I would imagine that would cause damage to a few things. There is a screen dimmer that keeps the screen *on* but has it dimmed to it appears to be off. I don't know what kind of long term effects it would have on the screen would be, because it is still on and has a slight glow to it.
http://www.xda-developers.com/andro...-screen-with-screen-standby-xda-developer-tv/
It is used for things like hooking up to your tv or computer to run things without having the screen on as well. I don't know if that will work or not.
I didn't have any luck changing my csc stuff, but I did have luck with ROM tool box finally freezing apps I wanted to, so well see how that plays out.

Cheers Smaw51 used your buldprop and systemUI giving it another go hopefully the reboot will stop anyway thanks

How do you know if it works or not? I am still getting power off during charge. After code was put in, it just wiped clean the dialer. Other codes I found I tested on my phone and tablet for various things all brought up a different screen thing.

Here are some codes I found here http://forum.xda-developers.com/showthread.php?t=1894102
*#197328640# Service Mode
*#7353# Self Test (Menu of 12 tests to use)
*#12580*369# --- Main Version (AP, CP, CSC, RF cal, HW Rev)
*#0*# another test
*#0011# service mode
*#0283# --- Loopback Test
*#232338# --- WlanMacAddress (Enable/Disable WiFi Powersave Mode)
*#197328640# --- Service Mode (Debugging, Testing. Use menu > back to go back in menus)
These look more promising:
*#7284# --- Phone Utility (USB Settings) I set both to PDA, didnt really seem to fix anything
*#9900# sysdump, has a few different things you can get for diagnosis stuff

Ill contact him to see if I can get the right one

I was thinking it was Kernel Panics when it tried to sleep.

What's odd (in my experience with both JellyNote and the German JB) is that it doesn't happen at a specific period after the device goes idle. Once it happened 2-3 minutes later, other times my Note sat there running fine for an hour or more before suddenly rebooting. I tried both using the ROM as normal, as well as once doing a complete wipe and re-install (of JellyNote) and not installing any additional software or tweaking settings beyond the startup wizard. Didn't seem to matter, I still got reboots at random intervals while idle.
It'd be nice if Samsung rolls out an N801X rom next.

In the v6 supercharger script there is an option to stop kernel panics and keep it from rebooting. Maybe this is the solution.

I have put this version of Jelly Bean on my N8010.
To start with I had a couple of reboots when the tab was idle. What I have subsequently done is:
Frozen com.sec.phone 1.0
Frozen Phone 4.1.1 - N8000XXBLJ9
In settings turned Blocking Mode on
I used Titanium Backup to freeze the programs. So far after a reboot I have not had any further reboots on idle - touch wood
Ok, I am not totally sure which of my changes or combination thereof has done the trick. Am afraid I am too impatient to use the new Jelly Bean to determine absolutely.
What I will say from my experience so far is the the tab is much faster than on ICS and stable for me to use all the time. So this seems a very good temporary solution until the offical N8010/N8013 roms come along.

Using Ondemand governor in a N8010 an the moment no reboots...it seems that the problem is the pegasusq governor

Wakelock after updating to Oreo beta

Some people in the Oreo Beta thread seem to think that its a Bluetooth wake lock and that if you turn off Bluetooth and then reboot your phone it goes away.
I had a wake lock problem before I figured out how to get BBS to work but it went away after a couple days. I'm not using the stock kernel though--I'm using Lightning Kernel which blocks some wakelocks automatically and allows you to block others using the ElementalEx kernel control app.

I use Bluetooth a lot and I'm not having that wakelock problem but the kernel I'm using might be blocking it. Several people have said if you turn of Bluetooth and then reboot your phone the wakelock goes away. It's definitely worth trying.
