My wife's trend plus is having the same problem, i belive is a software problem. Hope somebody will find a fix.

Have you tried just toggling airplane mode instead of restarting it? Are there any available firmware/software updates to try? There could be a better suited modem for your region as well.

Yup, i also tried the airplane mode and the signal still dead. The phone has the latest firmware, for the moment, hope samsung will make an update.
New modem? That means i have to reinstall a fresh firmware...Don't know what to say, the phone is in warranty and i don't want to risk.

If it's still under warranty, then might be time to see if they can help you with that...

Problem solved! By flashing a new firmware, specific to my country (romania) and the signal is coming back without restarting or turning off the device. Pff the problem persist...

I have this problem,but i don't know how to flash firmware? pls,help me...

Stock Galaxy S II (No root) stuck in flight mode

I got my Galaxy S II about 3 days ago and love it. Apart from some annoyances (I'm looking at you Touchwiz) no problems... installed Launcherpro and here we go
Today I woke up and bam. Flight mode.
Factory reset
Wipe USB storage and SD card
Wipe cache from recovery (stock recovery)
No change.
So now I have a very fancy Samsung Galaxy II Player. I called tech support and they asked me to try another sim (which I had done) then told me to clear the cache (which I had done) blah blah... then they ended up telling me to send it back to Amazon as faulty.
Great, just great.
Anyone else had this problem?
Nope, haven't had this.

I'm wondering... if I flashed an update.zip from stock recovery if the issue might go away... it's clearly software.
Just need to find an update.zip file....
Also something quirky is happening with regards to lock screens. Had unlock pattern enabled and then switched off however it still remains on but only needs a press on the screen to unlock.
Personally wouldn't try flashing if it's being funky. Last thing you want is to get stuck with non standard firmware if you still need to return it.

This sounds similar except I can't turn Aeroplane mode on or off.

I have the same problem with the phone that I bought today (a problem I noticed after 15 minutes of purchase). Tomorrow I bring it to a Samsung service center to confirm it as DOA so I can do the replacement for the operator ... I am disappointed that I was wasting my time on these things ...
p.s after I try code *2767*3855# a have no problems for last hour...
today i have problems again and I replace my galaxy...I hav new one without any problems...
I have a somewhat similar problem.
My Galaxy S II randomly goes into flight mode every now and then. It's not a permanent thing like what you guys experience, but it is an annoyance.
Couple that with the "wifi sharing" bug and I think we can say that Samsung has some faulty radio firmware in the Galaxy S II.

SGS2 running India distribution 2.3.3, unlocked. Not rooted. Stuck in flight mode, becacuse IMEI # cannot be read. Help !
could it be efs partition corruption?
It probably is /efs corruption. How do I recover it ?
Posting on behalf of my brother..
He to has this problem. Nothing we do fix's this resetting to factory defaults changing sim card formatting memory card..
Since it's done this.. it uses the battery from a full charge to near empty within ~5 hours
Bought 29th Aug 2011
They wont honor the warranty even though it broke down at only 2 months old.

Have you gone through Samsung directly? (Register on their website and request a repair).
I had this problem just now. Couldn't get it out of flight mode. Saying no sim etc...
The way I fixed it was to remove the sim and battery, replace them, turn the phone back on, the hold the power button to bring up the power options and press turn off flight mode. It now works again.
Not good that after I googled this problem it seems to be quite common.

I have this issue too, bloody annoying. I did a kernal update and I hope that fixes it. But will give your method ago.
My post is here - http://forum.xda-developers.com/showthread.php?p=21557309#post21557309
I had an interesting problem. My phone sometime stuck on flight mode. I had to restart device 4-5 times to disable flight mode(flight mode menu becomes transparent or untouchable). After a while button becomes enable and phone starts normally. But it's annoying problem.
Now I'm using Lite'ning Rom v1.1 XXLPH. Even in stock LPH,LPB, KK5 2.3.6.... every firmware I had same problems occasionally.
What's the problem? There is nothing wrong with IMEI (but I can't see IMEI in flight mode).
go in it recovery and clear data and then go to fix permissions

So is there a simple solution for this anoying problem, or it cames back every time ?
With Android 4.0 or 4.1 is the same?
I need to know as I am thinking of buying one that as this problem, at a good price.
Should i buy it?
thanks
Have you tried to reflash with kies?
I believe there is a recover option there? Atleast that wont get your waranty voided.
Never actually tried it since i only use heimdall & odin but might be worth a try!

kalpa108: galaxy gt i9003 stuck in flight mode, not reading SIM...and not recognised by recent version of KIES. Factory Reset does not fix this, device is not rooted, yet, but there's always a 1st time! Can this be done w/o any connection? Trying to download old KIES versions too.
Any layman ideas?
Yep. You're in the wrong forum, this in for I9100/variants.

wifi problem

Hi guys, there is a wifi problem with my phone currently. WIFI randomly disconnected and reconnected in about 5 seconds, and I am afraid it is a hardware problem, so I decide to handover it to the vodafone repair center. However, my phone has been rooted before, so I was wondering if after I install the TriangleAway and reset flash counter then the repair center wouldn't know I've rooted my phone? Do I have to do anything else to make sure? Thanks very much.

yes, I did everything, even tried to change the modem in my house, but no use. I guess it's the hardware problem. So after I install the stock rom and reset the flash counter, then I can have my warranty back?

[Q] SGSIII reboots just after start.

Hi. I have a SGSIII which doesn't work properly. Its previous owner told me that the phone had started work slowly so the owner decided to restore factory settings. After that operation he was not able to use SGS. It keeped restarting. He gave up and now this telephone belongs to me. When I try to run this phone telephone restarted as soon as the system started. I decided to flash SGS with stock firmware. I found the one which contained only one file (PDA). Unfortunately it didn't help me. Then, I installed CWM and CM11. But the problem still wasn't solved. Finally I decided to find four-file stock rom (Bootloader, PDA, PHONE, CSC), of course I still have the same problem. I've been looking for solution in the Internet and I'm afraid that could be hardware problem, what is more, it seems to be common. Do you, guys, have any ideas what can I do to fix this issue? Or can you confirm that is the hardware problem? Thanks in advance.

Dont know much but as long as the phone boots i dont think it should be a hardware problem but still it can be. Did you try takimg it to service?

Well I haven't tried taking it to service, because I am not sure if it is worth to repair this. Replacing the motherboard will be expensive so the better way will be buying another phone.
It could be a stuck power button... that can cause bootlooping type behavior. If the phone turns itself on when you put the battery in, but then reboots before it gets done booting it's likely the power button.

I don't think so the power button is guilty, becaue the telephone doesn't turn itself and it doesn't reboot until Android starts.

If you are looking for flashing back to stock S5, Google -> Sammobile -> Firmware -> Search for Galaxy S5.
Make sure you download the right version according to your device. You had it rooted so I assume you are not vendor locked. Download Mode, Odin, Flash and you should be good to go.
Or at least, that's what you are trying to do.
You're better off asking here.

I have similar issue with my phone after I updated to Android 7.0. It is at the Samsung service center now. Last update they shared - they have found manufacturing defect in my phone(2 year old phone). The problem is they also found that my charging port and screen is physically damaged and unless I pay them 300 AUD, they will not fix anything. I would like to assume my phone is gone. Any help will be highly appreciated.
