So, everything works great, except when I activate airplane mode via settings or notification menu, a problem occurs AFTER airplane mode is de-activated. Only the cell network is active, neither edge nor 4g connection is available UNTIL after a reboot. WiFi CAN activate but no cell network DATA available.
I attempted to:
1. search forums and google (similar issues noticed, no solution available)
2. flash stock Rogers radio then re flash CM7, didn't solve
3. Redo APN seetings with different inputs, didn't solve
4. shutdown remove sim, startup no sim, shutdown reinsert sim, startup, didn't solve
5. now on stable (seemingly faster) UCLA3 modem didn't solve
wipe emmc etc., flash SkyIceCream ROM, and then the problem solved!, wipe to factory and wipe cache, flash back to CM7, and the problem returns!
So I'm thinking it's the kernel and/or ROM. My device doesn't FC or SOD atm it seems very stable.
I use airplane mode a lot since I do travel on airplanes quite a bit. I can reboot after airplane mode every time but it's a pain plus sometimes I don't have the time to wait for a reboot literally. Please help, I love the ROM.
Hey brotha - I had a similar problem with mine. When we went on a trip to Phoenix, it took a good 10 minutes or so for the bloody network to come up. I had a bunch of data charges too when it did finally come up... but no description except medianet data charges (sent data not received). My wife's iphone also had some large charged data for sent. I don't know what it was, but the Phoenix market has LTE (obviously nothing to do with the iPhone) - but I figured that because our home network was not the same (4g here) that was a lot of ATT internal configuration fighting going on and it took a while for their systems to parse it out. All speculation and what not, but reboots on my phone wouldn't help until if finally popped open, but I'm betting it's not a device problem, it was a network issue (based on the 60ish meg upload charges we both had our our different phones... and no, we weren't posting airplane bathroom porn to youtube...
I couldn't take it anymore so i flashed nexusmod4 and now i don't have airplane mode problems anymore. So for anyone having this problem on CM7 don't worry you can fix it by flashing another ROM.
Hi
i have installed this awesome rom "Updated 3June12 [ROM][2.3.7][CWM] HebrewValhalla V3.4"
The word smooth has a sense
I have a signal issue.
when i go to an elevator without signal, the signal don't come back.
I have some bars in the signal bar but when i tried to call, i am getting Not Registered on network
it's not a sim issue, i have already replaced it.
Any ideas?
Did you try a reset and full wipe?
Your phone is picking up another network. Used to happen to me all the time. ATT has a stronger signal where I live and my phone would lock onto it for hours at a time. Didn't matter if I manually selected the carrier or not. After hours on the phone with Tmob they finally let me out of my contract.

If you were on a contract plan shouldnt it pick up the att towers as "roaming" since your t-mo towers werent as powerful?
If that is whats happening it explains why I cant get service in walmart. Im on the prepaid plan so no roaming for me.
No roaming agreement between ATT and Tmob at the time. It was right when the merger was being proposed. I confirmed it with Samsung as well. The device will look for the stronger network and try to connect to that. The crappy thing was you couldn't override it. I'd force Tmob as network and as soon as it dropped signal it would revert back to ATT.
Did you try flashing another modem? This ROM comes with sidekick KD1 modem. Some people prefer our native KI3, KJ1, KG4 or KJ6 modem.
I would also try to disable roaming option abd force a network.

Hi
Thanks for your answers
First, i am is israel. i am subscribed to the orange carrier
i have tried the wipe, the fix permission, the clean dalvik cache
i will follow your advice. i am flashing the Kj6
wait and see
If nothing else, one thing that works for me when I completely lose my network is to do a hard reset: Pull the battery, hold power button for 15 seconds, leave battery out for 10 minutes, put battery back in, boot and let sit another 10 minutes. Fixed.
Haven't had the issue on a bml ROM though(such as Valhalla), not sure if it's coincidence, but if all else falls, hopefully it will help you solve the issue. I tried flashing new modems, permissions, wipes, formats, flashing new ROM's, and that was the only thing to actually restore the network (restoring my efs may have worked, but didn't try it then, and that would only be applicable to an mtd ROM, unlike Valhalla)

Also try to switch it to GSM only, it might work.
when am selecting only GSM, the 3G don't work. i only get the G
BTW, each time that i restart the phone, i have to enable the GSM/WDCA.
after each restart, the phone is automatically configured to only GSM
Hi Guys
i am driving crazy
I have followed all those steps
1. Put ROM zip in SDcard.
2. Go to recovery mode.
3. Perform Wipe cache partition (3 times).
4. Perform Wipe data\Factory reset (3 times).
5. Perform Advanced -> Wipe dalvik cache (3 times).
6. Perform Voodoo -> Disable Lagfix.
7. Perform Voodoo -> System Lagfix Off.
8. Perform Install zip file - choose Hebrew valhall 3.5ROM zip.
9. Allow ROM to start, mount mount points, flash kernel and finish.
10. Go to 'Voodoo Settings'.
11.Perform Voodoo -> Enable Lagfix.
12.Perform Voodoo -> System Lagfix On.
13.Perform Back - Reboot System.
14. Let device stay untouched for 10 minutes.
Now i have another issue, each time that i restart the phone, i have to enable the GSM/WDCA.
when only GSM is selected, the 3G don't work. i only get the G
after each restart, the phone is automatically configured to only GSM.
Moreover, i don't have the standard gps issue of long lock.
( i have made the AngryGps Fix)
when i am using Waze, i am losing the Gps Signal
SOS
G.

RESOLVED
i have enabled bluetooth wifi, Gps and restart the phone
and the issue is fixed

Hi Heniki
I was on Israeli Orange and everything worked just fine. Now I'm on Rami Levi just paying 75% less..
Anyway, I suggest :
1. Try the Gremlin remover.
2. Re-flash ROM afterwards (try other ROMs if you must).
3. Check if your SIM is OK (try it with other SIMs).
4. Maybe SDCard is causing problems ?
The only problem I ever had with connectivity is that sometimes WiFi/3G/BT didn't want to start and the workaround I found at that time was :
1. Set 3G and BT on and restart the device.
2. Once device is up, turn BT off and 5 seconds later, turn 3G off.
3. If you want Wifi - just turn it on.
If you want BT - turn Wifi on, wait 5 sec, turn BT on. wait till it's up and turn Wifi off if you don't want it. Once you're done with BT, turn Wifi on - turn BT off and then Wifi Off.
4. If 3G/Wifi don't turn on, leave it on, set flight mode, wait 10 sec, then set flight mode off. It will work.
I don't have these issues lately (I'm on AntonX's 1.1.2 kernel).
If you must have a Hebrew ROM, know that I will publish a Hebrew CM7 and Hebrew MIUI next month.

I have the Rogers Samsung Galaxy SII running CyanogenMod 9. A couple of days ago I rebooted my phone and for some reason it got stuck on the CM boot screen. I tried unplugging the battery overnight but it still was just stuck on boot. So I wound up re-flashing the phone and installing CM9 again. Now I cannot get a data connection at all. Wi-fi works fine and I'm able to make and receive calls but for whatever reason it will just not connect to LTE/GSM.
I re-flashed the phone again, using a slightly older release of CM9. Still not connecting.
I have tried about 3 or 4 different modems. When I flash a new modem and reboot the phone, it will connect to data for about 5 mins. I will see the data connection flip between 3G and H+ numerous times and then the data connection will drop and I cannot get it back.
I've set my APN settings (ltemobile.apn) and I've gone into the phone settings via *#*#4636#*#* and tried various settings in there (LTE only, LTE/GSM pref, etc.) Still not connecting.
Any ideas? I feel like I've tried everything at this point.
My cellular radio seems to be permanently disabled on COS13. The problem happened completely at random (I picked up my phone and the cellular connection was gone). The phone is a brand-new replacement I got a few weeks ago.
Facts:
The quick settings in the drawer say airplane mode is off
The settings in the power menu say airplane mode is on
I cannot force connect to a cellular network (or view available networks)
The SIM works in another phone
I am running ZNH0EAS2JK
Things I have tried:
Formatting cache
Resetting phone
Removing and re-inserting SIM
Re-flashing through recovery
Has anyone else seen this problem? Any potential solutions would be greatly appreciated!
you could try formatting systen in TWRP and flashing a cm13 nightly. in this way the modem should be reflashed.
Hi all,
I have already spent a fair amount of time on various forums, trying to understand what happens on my Mate 8.
It's the second time this happens.
Usually, when i go to my prefered gsm network menu, I have 4 simple options : 2G, 3g only, 3G 2G Auto and 4H 3G 2G auto.
This morning, when I open this menu, I have 10 or 15 options (like cdma, lte, ev-do etc...) and of course, when this happens, the hotspot become non operative.
The first time it happend (last summer), i rebooted the phone from scratch, it went back ok.
Here are my questions : what happens? Why suddenly, the phone changes completly it's settings whtitout me doing anything in particular?
How can I make my regular settings come back, whithout having to reboot entirely the phone?
thank you .
Romain
What firmware do you have?
You can reboot to stock recovery and wipe cache could solve ur problem.
