After flashing Paranoid Android on my One, I decided to back onto ARHD 10.2 (Android Revolution HD) and all of a sudden, I'm getting this notification that says "No signal, limited service". No service at all. Note: I did a complete full wipe and everything before flashing back. The only way I can remedy it is by turning Airplane Mode on and then back off. After it says "Preparing SIM..." my service returns. This always occurs after a reboot. I do notice that the network mode defaults to GSM/WCDMA auto. I already tried going under Mobile Network Settings and using *#*#4636#*#* to toggle the preferred network, but it keeps going back to GSM/WCDMA auto. Any ideas on what I should do? Thanks in advance.
hi, i have the exact same issue with the HTC one international edition. have you found a solution?

I recently got Samsung GS2 to use on ATT in the US. Overall the phone works very well, however I keep getting "no service" at seemingly random times in known good cell reception sites (like my house). The phone appears to be working fine with 3-4 bars and then all of sudden the signal drops and I loose all connectivity for anywhere from 10 seconds to 3 minutes (wifi appears unaffected).
Here's what I've tried so far:
-Running stock KE7
-Downgrading my baseband to NEKD5
-Selecting "GSM only" in my network settings
-Disabling fast dormancy
-Running Lite'ning ROM just for kicks
None of these make the problem go away.
Please lmk if there's anything else I should try. Thanks in advance!
I am having the same issue on Vodaphone in the uk. Seems the only way i can avoid it is to hold the phone with finger tips top and bottom and not grip around the back! This also seems to improve wifi signal.
Sent from my GT-I9100 using XDA App
My problem doesn't seem to be related to how I hold the phone. I've tried holding it several different way, plus just keeping it laying flat on a table and it doesn't seem to make a difference...
I have a similar issue:
whenever I loose my 3G connection and there is no roaming GSM available the display show a "stop icon" in the upper display. That's ok... The problem is that when I put it where I know for sure there's the signal it won't reconnect but seems to stay disconnected (no service) forever! I have to force a Airplain Mode ON/OFF to make it search and catch again the signal in a few seconds. Never rooted the phone, official KG5.
My settings: WCDMA + GSM, packet data on (when in 3G, no roaming data allowed). H3G Italy.
I know at least 3 people who reported the same problem in Italy with different carriers.
Whenever it looses WCDMA + GSM, it hardly reconnects to the newtork leaving the phone in "No service", totally offline from calls too....
Finally fixed starting from fw KI4+!!
All,
I'm having a problem under two different ICS Roms (the "unofficial" leak and the ICS Objection RC3) where when I disable WIFI or move out of wifi range it takes several minutes for the data connection to establish. If I go to Settings -> About -> Status and watch while turning off WIFI I see "Mobile Network State" go to Connecting... and "Mobile Network Type" flip between HSPA:11, HSPAP:15, UTMS:3, then settle on HSPA:11 for several minutes. Then it flips through them again and settles on HSPAP:15 and boom I have data. This doesn't ALWAYS happen though, but about 90% of the time it does.
I've seen a few people mention this but nothing widespread in the forums - I'm worried it's related to my phone specifically. I flashed back to the stock gingerbread and the data switches are instantaneous every single time, so it doesn't seem to be hardware. Since this only happens on the ICS roms I'm assuming it's related to them but not sure where to check next. Any kind souls have any ideas to help me move forward? I'm currently on the ICS Objection RC3 rom and really don't want to go back
Thanks
I am having the same problem, I am on the stock ucle2 leaked rom not rooted, and it just started happing. After my wifi being on overnight I wake up and go to leave my house and my 3g/4g will not turn back on, I found that if I turn airplane on and then off again my data will turn back on. Does anyone know what would cause this, and any ideas on how to fix it?
Hello guys,
my problem relates to activating WiFi and/or mobile data on my phone.
First of all WiFi:
I'm used to enable it via status bar. But when clicked nothing happens but the symbol changing. When entering the WiFi settings through systemsettings WiFi is disabled. Enabling it there works fine, but is not what I would expect.
Before it worked fine.
Next problem.
When WiFi is enabled (it's most of the time when I'm at home) I disable mobile data (no matter if 2g or 3g). It runs over night till i leave home. Now when I want to enable mobile data, nothing happens. Even an analog work around described like above wouldn't work. The only way to get it working is to reboot the phone..
Any idea how to solve it?
My specs:
Samsung Galaxy S2 (int)
Kernel: Kernel_Siyah-Dorimanx-V9.10-[10-51]-[21-03]-JB-CM-AOKP-SGII-PWR-CORE
ROM: cm-10.1-20130321-NIGHTLY-i9100
Modem: I9100XXLS8
My fiancée and I got the same problem with the mobile data. I updated her phone with the latest nightly to be sure it's nothing that may have already been solved, so she got cm-10.1-20130320 nightly, I have yet to update from cm10, still running cm-10-20121209 nightly.
After turning on wifi or turning off mobile data (mobile data connection has to be interrupted) and leaving it off for a longer period of time, turning mobile data on again does not work. The button changes, the phone also reflects this in the data usage menu, the button is set to on, but nothing happens. Rebooting the phone then solves the problem, Mobile data can be turned on and off again for some time but leaving it turned off again will result in the same error. I hope this is somehow comprehensible.
Any idea what we can do about it?
I don't use CM anymore, but when I used to run CM9 that happened to me occasionally. Restoring a backup or reflashing the rom & kernel directly over the top of the current instal without wiping (if you're using another kernel) was the only thing that fixed it for me. You may find that reflashing the rom/kernel doesn't work; if it doesn't, I'd do a clean install (wipe/etc; tho I never had to do this to fix this problem).
Bizarre issue on SCH-I545 CM11 jflte nightly from April'15 and then on several CM12.1 jfltevzw nightlies from April thru mid-June'15: The GPS receiver works fine here in Phoenix, and in Portland, NorCal, etc. When I travel to Korea or Germany, or Costa Rica (GSM, not CDMA locations coincidentally), then the GPS seems like is it completely disabled / non-functional. GPS Status flashes up the active/searching icon in the notification bar for about 1 second, then it goes away. The GPS Status display shows zero satellites forever (tried for 10min). Not even one satellite showing on the signal strength bar or radar map. Zippo.
Tried deleting, resetting and downloading A-GPS data (via a wifi connection, not mobile data) does help. Note that I have mobile data roaming off, but cell service on and I can make/get calls and texts. Arrive back in the States and the GPS works again. Can't debug something that ain't broke! Damn it!
I'm not finding this issue in any forums. Is this a known issue? I'm on the MDK Baseband version. Will changing the modem package potentially fix this? (is it possible to change the modem SW without changing the bootloader from MDK?)
I read somewhere that the GPS radio may be on the same chip as the CDMA radio, and as soon as the phone figures out that CDMA is not available it disables this (portion of) the radio chip thus the GPS is disabled. To test this theory, here's my plan… Traveling from Phoenix to Munich tomorrow. When I land before taking the phone out of airplane mode I'll fire up GPSStatus and see if it is seeing satellites (and see how long it takes to lock). If so, then take it out of airplane mode and see if the GPS reception gets killed.
Other thoughts?

So here's the deal... I flew to Munich and sat in the airport courtyard for an hour dinking with my phone. First, before turning off airplane mode I tried to get a GPS lock. I let is sit for several minutes with no satellites found. I turned airplane mode off and the phone got on the local GSM network and I got the usual welcome message with usage rates. Data roaming was kept off. After a while of poking at various menus with no luck, I switch airplane mode back on and wallah! GPS reception. As soon as I turned on the voice/text cellular radio then no GPS reception. Very repeatable.
However, some menu that I had poked at made the phone not get back on Verizon when I came back home... "No service" in the notification bar. LTE data with strong signal worked find, but no voice/text service. Popped the SIM out and back in with reboots, and no luck. The only fix was to go back to recent CM 12.1 nandroid backup and everything is now fine.
I recall that previous to the nandroid reload that the Mobile network settings > Preferred network type > did not have the Global option once returning to the states. Global now shows in the menu on the 6/23 nightly.
Thoughts?

When I turn my wifi on, it does nothing. My hotspot doesn't work either. Problem started last week after I switched into airplane mode.
What I've tried:
-reboot phone
-cycle wifi and airplane mode
-clear cache and data for Android and Google processes
-reflash zv8 modem
-factory data reset
-wifi fixer android app
Nothing has worked so far. The only hardware change that i made was to replace the audio [headphone] jack and replace the battery with another brand new OEM battery.
LGG3 LS990
Sprint
Stock ZV8
Nova prime launcher
Stock kernel
Bumped and stumped
TWRP recovery
Any help would be appreciated.
I was able to resolve this issue. Apparently, there is an issue with the wifi and airplane mode on the lgg3 with lollipop 5.0. I found some other folks having the same issues on a t-mobile msg board.
What I did to resolve:
Turn wifi and wifi calling on.
Turn airplane mode on.
Long press wifi to view access points and wait for them to appear.
Disable airplane mode and select access point.
Problem solved.
In my case, it was absolutely a software issue. I will update if this issue returns.
Issue came back after an incoming call. Unable to get wifi back on using method stated previously. Still trying to mess with the phone.
Dangit.
