Network Issues after 1520 Cyan update

[1st_Raven]

Not sure if anyone else is getting this but I've updated my phone from WP8 (working fine) to 8.1 with the OTA cyan update and once the update was completed, the phone was showing it was in flight mode. I set it all up over wifi included a restore, and then disabled the flight mode to find that it is rapidlly switching between flight mode and mobile mode (active connection)

I've already done a hard reset and try quickly gone through the setup process again (no restore of my data) and the same thing happens.

I've now completed a restore back to WP8 using the Nokia tool (Mobile signal works fine) and have restarted a new download and upgrade process but has anyone else had this issue?

Video of the issue:

2nd update did exactly the same. Back to WP8 for me then. Strange that the DP8.1 worked fine when I was using it.

Mine is doing the same thing it's reallllyyyy annoying this needs to be fixed ASAP

 

[1st_Raven]

Mine has gone back to Nokia to be repair under warranty. I'll let you know if it comes back fixed.

Strange ... Though I noticed a relatively poor reception and problems with internet connectivity and mail syncing after update I soft reset it yesterday and its ok now I hope.I would hate it if bugs persist coz 8.1 is a huge upgrade from WP 8

These are NOT OS bugs...
Sounds like a network issue if it is now working fine. I don't understand why every little 'blip' is a 'bug that needs to be fixed'... Not everything is Microsoft's fault!!!!

Anyway, I'm glad it's working again.

It would appear that mine was a hardware issue, which was strange that it only appeared with the Cyan update, something that I proved multiple times. Even a different sim card on a different network didn't fix the issue.

I'll see when I get my phone back from Nokia's warranty repair to see exactly what was wrong.

If that was meant for my post yeah its bug coz it was working fine with WP 8. So don't judge.
If it was not meant for my post sorry.

I wasn't judging, hence the "Anyway, I'm glad it's working again." part.....

Yeah its a great tactic to land safely and say you were not judging after actually judging and say what they say is wrong with no basis lol.

I am having same issue mentioned above on my Lumia 1520. Its working well with WP 8.0. itried atleast 5times with different network SIM. no luck.
Is anybody have any solution for Network Issues after 1520 Cyan update. Thanks

 

[1st_Raven]

Well, I've received my phone back from Nokia care and their 'repair' which is to downgrade the phone to 8.0 and leave it then. Just wonderful.

I'm talking with NokiaCareUS about this but so far no solution. Will keep people updated.

I had a chat with Microsoft support and they advised me to downgrade to 8.0 by using Nokia Software Recovery tool and then again upgrade to 8.1 to check if is solves Wi-Fi connectivity issues and Call drops. But it did not resolve the problem.

I have replied them to escalate further as said by support person in his reply.

This doesn't sound like an isolated issue.
I downgraded my 1520 (apace Hong Kong_222) to 8, (after having 8.1 update 1DP - which everything was working fine), to get the Cyan firmware update, as well as 8.1 (and updated that to 8.1 update 1DP). I'm in Australia on Telstra Carrier.

Mine does not actually show it is in Flight Mode - I can still make calls but every time I try to use my cellular data it says I need to turn it on (which it is). The only difference being Cyan firmware -
I expect this is related to the above users issues... looking for a fix too.

Update - seems as though the update somehow blew the APN settings. I manually entered the APN settings for my Carrier (haven't done that for a long time), but data is working fine again.

Yours sounds much better than mine, I can't make calls at all. When i try to make a call, it asks me to turn it on, but it never actually does turn on.

Just updated my 1520, all went well but now I don't seem to have a stable Wi-Fi connection, it keeps on going from connected to searching, it doesn't say that flight mode is selected.

Will do a restart after me dinner.

Yeah, I now have this exact same issue and the symptoms are the same as your video shows. 1520 with Cyan update as well. Tried the software recovery tool and reset everything, but no change, happens even after completely clean reset. Unable to revert back to WP8 after Cyan is updated though. Taking the phone to a service facility soon... It did work for a long while, I updated to Cyan on July 25th like a month ago.

I'm having the same issue with my 1520. I tried reverting back to 8.0 using the nokia recovery tool but the only option is 02061.00066.14253.40001. Are there any other options to get back to 8.0?

I don't think there's a way to go back if the tool is restoring to Cyan/8.1. I have a copy of the Black/8.0 firmware, though, if you can think of a way to get it from me.
