[Q] Stuck on Flight Mode ON - No Wifi, No Bluetooth, No Cellnetwork

I dropped my phone in the water. Got the battery out quickly and opened up the phone from A to Z (except the circuitry under the screen) and got it dry, left it to dry for 48 hours on top.
Now, my phone is back together and it boots, screen works, sound works, OS works.
But the phone is always in Airplane mode when I boot it. If I try to change the Airplane Mode to Off from the menu shown while pressing Power, it says it turned it Off, but it's then greyed out (can't turn it On and says its off). If I go in the Settings in Wireless settings, Flight mode is still on. If I try to turn it Off from there, it says, turning on wireless things.. but stays there.. If i go <-back and go back into Wireless settings, flight mode is still On. If I go in Wifi settings, the wifi is off, if I select it to be on, it starts scanning and eventually says: Unable to scan networks.
So, I'm wondering, what part is busted ? Anyone know ? My connections seem to be OK, I've put it back as it was. I'm basically bummed.
Also, in settings-status my IMEI is unknown and pretty much everything relating to connectivity. USB works though.
Any ideas? tricks ? anything ? other than buying a new phone to replace this one.
Cheers.

Cell Radio off and imei erased

It says its in airplane mode but wifi works . I used myth tools to go back to stock and now it shows my phone number in settings but thats the only difference . When I try to make a call it says airplane mode on would you like to turn off , I hit yes then it says turning radio on but then it just goes back to home screen after 15 seconds . I had this happen once b4 and I just sent it back to att but now the warranty is over so any help would be greatly appreciated thanks.

no cell service, sim not detected, airplane mode stuck on

Recently, when I would reboot my phone, or battery pull, or anything that turns the phone off, it will not have service, nor detect a sim when it turns back on. A new sim card didnt help. wipe cache/dalvik/ flashed new rom did not help.
It seems to boot into airplane mode and never come out of it. I have created tasker toggles with secure settings to forcefully turn airplane mode on and off, but 'no service' still shows in my notification bar, both with airplane mode on and off.
After using tasker+secure setting and leaving the phone off for whole day I got service back, and made a phone call. When I rebooted again the problem came back.
is there a boot script or xml i can edit to ensure airplane mode is not on at boot? The phone seems really confused as to whether it is on airplane mode or not.
ATT Note 3 running dynakat 5.0 edit: flashed 7.1 and still problem persists
just wiped and flashed dynakat 7.1 and still no sim card detection.
Mine does that sometime. I just hit *#*#4636#*#* and hit device information and it usually connects after a few seconds. Idk what it does when i hit that but it recconects everything. Its worth a try

Hmm. That number doesn't work for me, though it used to open up cell settings. For some reason my phone is starting in airplane mode. I'll try wiping cache again.
*#*#4636#*#* didnt do anything for my on Dynakat but i just flashed firekat and got into the phone settings. Here's what they look like. The 'turn radio on' button doesn't do anything. The third picture shows the phone not knowing in what state of airplane mode its in. The options say its off, but the notification bar says it is on.
Flashed the 4.4.4 NL1 odin tars found here, http://forum.xda-developers.com/note-3-att/general/kitkat-4-4-4-n900aucudnl1-odin-tars-t2999317. 2g works but no data connection. Guess im gonna have to send it in.

Mobile Data turns on after reboot, WITHOUT permission.....

Anyone else experience this? After I restart the phone, WITH mobile data OFF, the OS boots up & along with it the mobile data turns back on. FYI, I also have Smart Network Switch off, AND Wi-Fi is off as well. I can even reboot with Airplane mode on, and after it boots, I turn off Airplane mode, and mobile data turns itself on again! Please help and assure me my phone isn't possessed! I believe this happened with my Note 5 as well, and somehow it went away. Cant remember what i did, so long ago! To add to all that, neither is/was rooted and both at the time were freshly bought and turned on! Hope to hear some good things from you all!
