Hello all,
I have an old Samsung Captivate laying around that I have turned into a media center remote control. There is no SIM card in the device and there likely never will be in the future. I have loaded Slim ICS (gotta love ICS!) on it and it runs great, but what I would like to do is COMPLETELY disable the cellular radio. I have no need for it and I know that having the radio active, even if it is not connected to an AT&T network, is still draining battery slightly. I want to know if there is some modem out there that I can flash that will be able to shut the cellular radio off totally, or at least give me the option to turn it off. I know this may sound dumb, but please bear with me. I basically just want to eliminate unnecessary hardware. I would also like a way to physically disable GPS if possible, but that's another topic for another day.
Thanks in advance to anyone who even takes the time to read this thread

You can use airplane mode.
Or can't you just delete the modem?

Here is a ROM that was the same idea.
http://forum.xda-developers.com/showthread.php?t=1093696
A guy on the last page says he just uses TiBu to freeze all the MMS and Phone stuff in Sliim ICS.
Just deleting modem will probably disable the wifi. That rom listed above had the basic idea. You could just use airplane mode and have working wifi.

My g1 have big problem, it loss signal all day, most the time. I tried turn on air plane mode and turn off, or retart the phone, wipe, up another rom, up newest radio version, use 2g network only. But it doesn't work.
It loss signal random, i can't control or do something to have signal again. even i change many other sim cards. but i discover one thing: seem this problem related air plane mode. because in some rom version, i turned off air plane mode but it didnt, even i restart my phone it still on. i must take out the battery for long time and put it again.
Some time it have signal again but it only for short time.
How can i fix this problem, please help me.
please someone can help me. my phone isn't a phone anymore
hhmmm...Try to upgrade to the latest radio for g1. If that doesn't help, maybe your rom has messed up apn settings or the service in your area dropped.

I can add few things to this since I experience loss of signal multiple times every day:
I have 2 G1s. On both of them it happens:
1. Using different ROMS (CM, Super-D, OpenEclair)
2. Using different recoveries (RA 1.5.2 and 1.6.2)
3. At different times of the day
4. Using different radios (older radio and the newest one, sorry I can never remember the numbers)
5. Across different states ( I took one of them thru 5 different states and it kept loosing signal)
What happens is that I start a program that requires data (twidroid, FB, Gmail, Market) and I see my connection get stuck on the uplink, go away completely and restart the radio. Another way it will do it, is that it will stay on blank screen (or downloading screen) and there will be no uplink or downlink shown)
Tried: wiping, re-flashing radio, re-flashing rom, getting rid of few apps.
Anyone with any insight on this? I can get a log next time this happens if anyone wants to take a look.
Thank!
i tried many diferent rom, radio, and recorvery too. but it still doesn't work?
Now i discover that any connect in my g1 seem doesn't work. wifi can search but when i connected it can't open any page even google. gps can receavie signal, bluetooth can turn on but no one can see me or i can' connect to my headset bluetooth.
May i think it is mainboard's problem? i opened my g1 and see anten signal very perfect, don't have any space or something like that.
What's up everyone.
I just got the G2 (nice) and so my 3 year old is getting his first smart phone. Issue is, I don't want him to actually have call capabilities... so in a nutshell I need to disable only the cell radio on my G1 but want to leave WiFi and BT on.
I've seen several posts on this subject but generally the answer is to set up one of the power management apps or yank the SIM card (already done.) I want to make 100% sure he doesn't end up accidentally calling 911 though and it seems to me the most thorough way to ensure he doesn't is to cut the radio altogether.
I just downgraded from CM6 back to 1.6 (DRC83) but will root/reinstall if needed.
Thanks in advance for any suggestions you might have.

What if you remove Dialer.apk? That would eliminate a possibility of calling anywhere
Let us know if it works, I've been dying to do that to my old G1 but never get around to actually doing it.
I don't known what happening with my phone, everytime I enable data it doesn't connect immediately to internet (3g/2g), I need to enable/disable airplane mode to get internet works.
It's sucks, I don't known If it's rom, phone, network related issue. I'm thinking to sell this phone just because this. It's really bother me.
Is there any way to known how to causing this, or any workaround for this?

Just don't use that particular miui. Use another stable rom. MIUI always has new betas with buggs. Normally u could just update, but they stopped supporting Gingerbread roms. Or downgrade.
For some reason my Galaxy S+ seems to want to use Mobile Data instead of Wifi. This started happening a month ago. Around night times it will just swap to using Mobile Data, but Wifi is still turned on... I don't understand why it's doing this. I am not going out of range of Wifi or anything. It says that my Wifi is connected in settings but the phone isn't using it. There is also no icon for it, just for Data.
It has nothing to do with my network because my Galaxy S 2 doesn't have this issue...
Also the phone goes on Silent by itself too... and no, I have no program that makes it do that automatically... so I have no idea what is going on.
Are you absolutely sure that you don't use any app like Tasker or something? That simply sounds too strange. Or maybe Juice Defender? If I remember correctly, there is a night profile option or something.
List the apps you have installed, if the phone is doing this each night it is definitely a profile set.

Some SGS+ roms (even stock) have known issues with wifi drops. If you want to keep using your current rom I think you have to install KQ1 wifi drivers...
In any case the best solution is to flash a rom without any wifi bugs such as KQ1 or KQE.
This is the link for KQE thread in the android development forum... In any case you can download all roms in sammobile
(I'm using KQE and don't have any wifi bugs )
I have just received a new galaxy S5 so i would like to turn my old S3 into an ipod touch like mp3 player.
The only functionality required is a long battery life, the ability to play music from internal storage, home server and internet (via wifi only, no cellular connection will be available so i would also like to remove all of the apps associated with calling, messaging etc.)
Dose anyone have any recommendations for Firmware, Kernels and Apps to help me achieve this.
I am currently running SlimKat 4.4.2 Build 4.8.
I have found a mod to disable Cell services and remove the associated apk's, I will be testing it out shortly.
What it does:
Removes unnecessary apps (Messaging.apk, Phone.apk, TelephonyProvider.apk, Mms.apk, TelocationProvider.apk)
Completely turns off cell radio on bootup
Installs the radiooptions binary in case your ROM does not include it
Prevents emergency calls and 911 calls (good for giving your kids your old phone to play with)
Unfortunatly i can't post links but the mod is on rootzwiki [MOD]Any phone, any ROM: Wi-Fi only mode (disable cell radio)

The phone was found on the side of a major highway with a cracked screen and has had the IMEI blocked, so its not really worth selling it.
I was just trying to make as much use of it as i could.
Oh, fair enough. What about Airplane mode and then activate WiFi? After that you can activate the power saving mode on CM 11. I have 0 experience with kernels for this phone so I'm doing my research atm (That's why I found this thread on the first place).
Also, right now I'm looking at the Sound Mod AC!D Audio Technology maybe you're interested in this too, I don't know how this mod affects battery life as I haven't tried yet but it is supposed to increase the sound quality by A LOT.
This is all new to me as well this is my first attempt at modding anything android (apart from installing pre-made roms, etc)
Thanks for the sound mod ill give it a test run.
Flight mode works to a point, while the phone is in Flight mode the cell radio is still active and searching for emergency signal therefore still using battery (as can be seen in battery stats as cell standby).
Because my phone is IMEI blocked and i always have my S5 with me i have no need for the emergency signal on this device so i would like to find a way to totally disable the cell radio. I just had the thought of taking the rom from a tablet device that has no cell radio to begin with and see if that works on the s3.

No it doesn't The only ones that did that were some Nokias. Try this, set network to GPRS/2G only, and then enable airplane mode. Remember the i9305 has a external modem due to the 4G, made by qualcomm.
