When you put the phone into Airplane Mode, does the cell radio actually get turned off, or just to a low power state that still broadcasts to towers?
Is anyone able to answer the question? Or does everyone at XDA secretly work for the NSA?
Yes, the radio is turned off. You can confirm this in the dialer menu->phone info.

I mean I guess the reason I ask this question is because the radio firmware on most if not all phones is closed source, and hence we don't really know what it does when you tell it to turn off. Is there ever such a thing as an open modem for GSM?
In regular Linux, some WiFi radios have fully open source drivers.

Suddenly this morning my GSM died. No, it actually didn't die. When I go to phone settings/network and choose manual, it searches and finds all networks in my region, but then I choose the network my SIM belongs to and the phone says it cannot register on the network. I tried flashing a new radio, stripped ATT radio, new ROM etc. always the same problem. By the way the green flashing led is not working as well. When the phone initially boots, the GSM version is displayed correctly.
So, did anybody had a similar problem before?
somehow it is working back now after over 36 hours of death. I left it in airplane mode through the night and replaced the battery before going to sleep (I had a spare). Now it is functional. I don't know what the problem was, but may be the battery. I will try it with the other battery later and let you know.
after the latest update which is 45.2.7MB855.Sprint.en.US was shown in system updates, i installed the update but after updated my wifi wont turn on, it says error everytime I try to turn it on.
Note : Im using Photon outside US running GSM, I dont this this will make any difference right?
Actually it is the problem haha. When the phone turns on, it searches for a sprint network even if u set it to gsm only. And for some reason if it doesn't find a sprint network, it freezes up the 4G and wifi radios. Only thing that worked once in a while was put it on airplane mode, reboot. Wifi works then. Have somehow got it working alongside a gsm network a couple of times by trying to contact sprint servers while taking it off airplane mode but after 20mins, phone overheats and restarts. Not the most ideal situation. So no solution yet. Hopefully motorola/sprint fix it soon

Freeze SprintOmaDmPlugin.apk and you will no longer have this problem...
Oh, and this will also resolve the Activation screen after each reboot problem...

I don't think mine searches for sprint network because I had mine activated from sprint, and phone was working just fine before the update the wifi error came right after I updated, I think its the updatethat have caused it
Sent from my Transformer TF101 using Tapatalk
If I'm not mistaken, the update resets the activation. I know I read a thread somewhere that said this. I cannot be sure because mine's not activated.
Anyway, to freeze SprintOmaDmPlugin.apk, you'll have to download Titanium Backup. You also need to be rooted...
If you're not rooted, instructions can be found here: http://forum.xda-developers.com/showthread.php?t=1217416

Hi, posting here to not create a new thread about this.
I have a Mopho and i am using it outside US, it doesnt give me much trouble after the initial loading screen "looking for network" and stuff from sprint.
I did the freeze SprintOmaDmPlugin.apk with titanium backup and it did work to eliminate the searching screen, however, the phone now never asks for my pin code, that means i cant connect to anything, i can easly turn back on the SprintOmaDmPlugin.apk but that makes the searching screen start up.
Is there anything that can be done about this?
Phone is brand new, stock everything just rooted.
Thanks.
use this patch correct wifi error
That patch does not work.
Motorola has posted the file, try reading the readme
brains fried from plan flight, so please help.

running CM7, went to Singapore for the week, used battery monitor widget to set radio to GSM auto for the time i was there, now im back in the states and not able to get it back to CDMA. it keeps defaulting back to gsm auto.
i can select any network and go to my home, once i look again, its still at gsm auto. ive tried changing with radio off and on, and such. :/
have you reflashed? you wont loose anything.
also check this out, don't know if related but might help.

I use my HTC Legend as a backup phone (well planned to anyway). It is s-off, rooted and running cm7 (same thing happened on cm9 and 10). The phone initially was working fine - however one time the phone's battery was running low so decided to shove on airplane mode. I simply could not turn this off - when attempting to disable, nothing would happen and would just stay on. It took me numerous different wipes of the phones data/everything i could think of plus flashing multiple roms until i could get out of airplane mode. It again worked for a while - however, since this isnt my main phone there isnt always a sim card in it. I tried using the phone this weekend - when inserting the sim and turning the phone on - boof! airplane mode activated and unable to disable.
Has anyone else experienced such issues ?
I'm using a micro-sim card with a simcard adaptor in the phone. Could this somehow be triggering this ?

That is such a strange problem. When I was in the States, I overheard some people complain that their SGSIIIs (and one guy's SGSII) would randomly turn on Airplane Mode whenever they dropped signal or service. The SGSII guy could resolve the issue by doing a battery pull. All of them were on Verizon.
I can't really think of any other triggers to this problem. Do you have any apps that are allowed to turn Airplane Mode on automatically? Tasker? Some new CM7 Power Saving feature?
I run a MicroSIM card in my Legend with an adapter as well, this is my second MicroSIM with this phone. I don't believe that would be an issue.
Unless for some reason the SIM was not an actual MicroSIM but rather a regular SIM cut quite poorly, or in any circumstance disallowed the SIM to behave like it usually should, therefore cutting the signal and activating the Airplane Mode glitch like the others above have had.

Thanks heaps for your fast response - i wish it was as simple as a battery pull! haha - and nope only have about 3 apps on the phone (ebay, facebook and tapatalk) hmm ill try if i can grab a normal sim card to test - as my micro-sim was cut down from a normal sim - however ive had no other issues on other phones.
If not ill try flash a stock rom if i can find one.Thanks.
Yep! seems it's my sim card - just tried using a standard sim and all worked fine! strange considering initially it was working fine.

Ouch. Maybe you can ask your carrier to issue a new standard sim so you can try cutting it again without incident this time.
Or, if possible, try to buy a brand new microsim straight from the carrier. That would be the best and economical plan of action.

Hello,
I'm losing my wits, hope you can help me..
My G2 mini (new) worked flawlessly for a couple of weeks, then suddenly lost all network signal. After a few days, thinking it was a software issue, i unlocked the bootloader, rooted the phone, and installed CM11. An hour later - full GSM signal. For a few hours.. Since then, i've been having random x hours with, y hours without GSM signal, with absolutely no reason for the changes (phone laying on the table, absolutely no user input).
It might very well be a hardware issue, but my google-fu failed me big time, all i seem to find are GPS issues (which is not the case here, especially since i don't need GPS on this particular device).
Here's a breakdown:
- The phone originally worked with no signal loss (original OS)
- Unlocked bootloader, rooted, installed CM11
- Signal works for a few hours every day (random pattern), loses it just as miraculously.
- Device finds no networks when using the in-built search functions, but i receive no error message. When using Automatic registration, the phone displays: "Can't connect to this network right now. Try again later".
- My SIM card works fine in my D802, same issues occur on the D620 with a different SIM card (which also works without fault in the D802), so it's definitely a phone issue.
Questions: Anyone have any idea what's going on? Could it be a baseband flaw? Is there a way to (re)install the baseband, to eliminate any possible software issues?
I have disassembled the case, and all pins have wear marks embedded, which means there's plenty of contact, as far as i can see.
Thanks in advance, guys!

Unfortunately, my issue seems much more severe. Toggling the airplane mode, restarting the phone, nothing seems to work. It just regains the signal whenever it feels like it. For instance, it's been "off" for a few days now, with the exception of 2-3 hours a couple of days ago.
Thanks for your input, though!

With the latest release the problem disappeared. With previous releases I would open the phone sometimes and it wouldn't have any signal. I either had to restart it or toggle airplane mode on and off....
