CM7 Galaxy LTE post airplane mode no data issue - AT&T Samsung Galaxy S II Skyrocket SGH-I727

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.

Not Registered on netword

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.
G.
RESOLVED
i have enabled bluetooth wifi, Gps and restart the phone
and the issue is fixed
Is "netword" a new game like Scrabble or something?
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.

Lost LTE and internet access on some Wi-Fi networks after flashing Cyanogenmod

This is the first help post for anything tech-related that I've ever posted- I'm usually good enough with Google to fix my own problems, but this one has me flustered.
Until yesterday I was running DigitalHigh's GPE ROM but decided to give Cyanogenmod another try after some persistent lag issues. Everything went fine during the install until I noticed that I was stuck on 3G no matter what I did- airplane mode, reboot, clear the cache, try to update APN settings, etc., nothing helped. Additionally, while the phone will connect to my home wireless network, it has a ! next to the connection symbol despite my being able to use the network with my laptop. The funny thing is, this only happens with some networks. Neither my home network nor the network at work will give me internet access, but if I plug an ethernet cable into my laptop and create an access point that way, I'm fine.
Here's what I've tried so far after scouring these and other forums:
-Reverted back to the previous ROM
-Flashed new firmware
-Flashed two new kernels
-Tried every different APN setting I can think of
-Popped out my sim card, waited a bit, and popped it back in
-Rebooted countless times
-Cleared every cache I can think of
-updated TWRP
There's probably more that I can't think of off the top of my head as well. Does anybody have any idea what on earth has happened to my phone?

modem_err - signal loss - random-reboot - high battery drain

Hi,
my phone lately shows an high battery drain, random reboots and signal losses.
Aside from supersu and adaway everything is stock. last-kmsg shows "modem_err"
A few days ago I updated my phone from MMB29V to MOB30H, right after this I went on holiday. (left country)
While being there everything worked fine.
But right after I comeback home the phone started to act strange (see title).
Anyone an idea what could cause the behaviour?
Maybe the update? And I didn't noticed it in holiday because of my disabled data connection?
I tried:
a full wipe, reflash of stock image
flash of old radio
looked out for wake locks (there are non)
using phone without apps (only stock)
Might flashing old bootloader/kernel help?
Maybe interesting:
My provider (Klarmobil (T-Mobile DE third-party)) tends to switch my network mode between 3G and HSPA,
from what I heard and see this depends on my data usage. (HSPA while surfing, 3G while idling). I have the "feeling"
it disconnects when it tries to switch.
Thanks for your help!
Edit:
Added another set of logfiles, showing a "signal-loss", it got so far to ask for my pin again.
Sadly errors still keep happening. I tried the march build and also a custom kernel, no change :crying:

LG G5 Sim not detected only for SMS and calls

As stated I'm using the LG G5 H830 T-Mobile variant. I am getting 4G LTE data connection and everything runs well (Not in any WiFi range) Yet for SMS and calling as well as mobile hotspot I get "No USIM card' error. This happened after wiping the system and formatting data. Rebooted recovery (as per instructions on forum) then installed the stock firmware & Patch with systemless root and xposed. After this I did factor reset when just pulling the sim didn't help. Still nothing. I reflashed just the stock firmware with TWRP and SuperSU and issue is still happening. I've disabled rebooted and enabled the phone radio. SIM is in good condition and tray as well everything is SECURE and should be good to go.
I'm assuming a new SIM might be a solution. But I'm not counting on it and with Labor Day tomorrow for me I wouldn't be able to pick one up for 2 days. So here I am...hoping someone might have a fix. I know I don't have many posts on here. But I am an experienced user....just not with the more basic of problems I guess
Thanks!!
Has anyone else experienced this yet? I'm just curious...I had it fixed for a couple days. I've formatted data and done complete system wipe. Tried it resetting phone with the COMPLETE zip and TOT using LGUP. I'm receiving texts. Not calls. Not able to send either. I've activated new sim, didn't help. LG support just told me to look into warranty. T-Mobile needless to say just wanted. Sim card does show stock tmobile short code contacts but phone number shows as unknown. Hotspot won't work. I've tried setting the phone number to the sim. Nothing.
Anyways. I don't think I messed with anything, even so I've done everything to start the phone from scratch. Going to replace it, just more or less curious at this point and maybe others have had the same issue.
I believe I had the same issue as you and it was driving me crazy. I was constantly wiping data, system, etc but my phone kept giving the message "roaming indicator off" where it should show the name of the carrier. This resulted in me having LTE data and that's it- no 3g, no phone calls, etc. I couldn't even access the mobile network menu.
What ended up causing the issue was the network mode setting under wireless networks. Keep in mind at this point I'm running a patched rom which now gives more options in the network mode menu than the phone came factory with. I have an area at work where I have to switch to 3g, GSM/wcdma preferred network setting, because although I have full LTE signal, my connection goes dead. When switching back from 3g I chose the setting lte/CDMA thinking this would force my phone to stay in lte mode due to another area on an upper floor where the phone will constantly drop lte.
Anyways this resulted in my phone saying roaming indicator unavailable, the inability to make or receive phone calls, and either the mobile networks or network mode menus being grayed out. When stuck in this mode there is no way to put the phone back into the standard "GSM/wcdma/lte" mode. Even a complete reflash won't fix it. I even used lgup, which worked for maybe a day until it force closed the phone app and went back to roaming indicator unavail. I wiped every partition and even reflashed radio firmware. Nothing worked.
What ended up fixing it was using an app called v10 hidden settings which allowed me to access the network mode menu directly and re-choose the lte/wcdma/GSM setting. Incidentally on first access to this menu through the app there are only two network settings available. Once you choose a GSM setting, the rest appear.
I'm not sure if this was your issue but I hoped this helped because this took me about a week to workout.
