Nokia Lumia 520( cyan) : Airplane mode stuck and rapidly switching on and off

CareSuite servers are offline, could you (or anybody else) upload 1.5GB file?

Try to change batteries with a working Lumia 520. This worked for me.

On a side note, I had convinced people to switch to Windows Phone too and was more than dissapointed with the Lumia 520 experience.

Sadly the time WP was a win win (fast, reliable, simple, nice, short boot times, people hub integration) was in the Windows Phone 7 era.

I had a Samsung Focus (i917) and it was a blast compared to this Lumia.

hi I am writing from Iran . i gave my phone to Nokia service center to replace my screen but they do something that an IC called mobile ECU malfunctioning and that is the sim card and network processor they call it the hearth of mobile phone too . so it must be changed by a very professional Nokia repaire center so go to the Nokia or Microsoft after sale service to replace your IC. that's all I know. bye

My phone also did the exact same thing...earoplane mode and rapidly switching on and off from aeroplane mode...i did recovery of the phone...all software was recovered but still the same problem persists... it must therefore be a hardware problem...but what could the problem be is what seems to be the question on everyones tongue...does Anybody have an answer for us please?

I was using Lumia Black and updated it to 8.1 ( Cyan) from my phone itself ( official release). I updated to Cyan OS not longer than a month back. Everything was fine, until recently, a couple of days earlier, when I was talking to a freind of mine on my phone, the call dropped. A notification to restart my phone appered so I did it. Ever since I am stuck on the , " Airplane mode". The flight mode will rapidly switch on and off. So, I am unable to use my Sim and thus, no whatsapp, no calls..social life has been paralyzed. 

I tried Hard reset ( about menu-> reset your phone) :- three times

Soft reset:- several times

Changed SIM :- a dozen times

Tried the twitter team suggestion ( I had found on this forum itself :- http://discussions.nokia.com/t5/Nokia-Lumia/Lumia-1520-3-and-official-8-1-stuck-airplane-mode/td-p/2855086)

Now trying Nokia Software Recovery Tool 1.5.0 but the problem is that it is downloading 3058.50000.1425.0001, which I beleive is 'Cyan' again. I am also worried, I won't be able to downgrade to Lumia black  which I am missing a lot. Anwho, I am  currently downloading it and will see what happens, but If Nokia's Technical team can provide a solution for this software/firmware related glitch, I will be a happy fella. I am wondering, about the first occurence of this problem which I researched as being reported on Nokia official forums, 2-3 months back. By now a trustworthy solution should have been found and posted online.

I know I am a bit late to the party.

Very recently, I too fell in the same trap and tried a lot many things in vain.

But then, I followed the instructions stated here : http://forums.windowscentral.com/nokia-lumia-520/243898-guide-users-who-didnt-get-proper-amber-update.html

It worked like a charm - but yes - it would essentially be taking the software to a lower version.

After installing the lower version, you may choose to go to phone updates > keep on updating until in one upgrade - it says that it will be upgraded to 8.1 - proceed no more [or else the phone again goes back to permanent flight mode].

Hope it helps.
