[Q] No mobile data after Kit Kat 4.4.2 update

Hello,
just found this forum and hope to find help with my problem.
I received an OTA update from Jelly Bean to Kit Kat 4.4.2 three day ago.
I bought the phone in US but use it in Germany.
No problem for over a year with Jelly Bean.
Since the update the mobile data connection is not working.
I reset the phone to factory settings, mobile data is activated, APN is entered.
No connection.
WiFi works so far, but it seems from time to time it switches off by itself.
I need the mobile connection, otherwise the phone is useless for me.
Is there a possibility to flash it with Jelly Bean, or to get somewhere a Kit Kat version not Verizon based.

If I can't get it to work, it seems I need to get a new phone.
Any help or suggestion is highly appreciated.
Thanks
Urb

No mobile data after Kit Kat 4.4.2 update

Thanks for your answer.

Yes I tried to change through different network setting to no avail.
I used this phone for 1,5 years in Germany without a problem, until the upgrade to kitkat 4.4.2
I am not sure what you mean by locked/unlocked.
It's open for all network operators.

How can I downgrade the phone?

Maybe the OTE upgrade was faulty. It seems I can not use WIfi and Bluetooth at the same time, another bug?
I would try to install the system a second time, if thats possible.
It would be a shame to kick the phone, I was quite fond of it until this whole mess started.

Thanks

Thanks

I checked, it's locked.
I will try the link you recommended. As it seems the only way, I am not sure if it will work anyway. Just my suspicion that the OTA download was faulty.

Thanks for the support

Hi,
thanks for the link, I was scared to start the whole process, so I decided to check if another sim card would have similar problems.
It turned out, another sim card worked just fine.
I started to realize that it must be a UIE, or at least a partial one.
So I remembered that my current sim card, which has been working 1,5 years without fault, used to work beforehand in a Blackberry 9800.
So I guess the KitKat update somehow blocked the services, phoned the service provider, and they switched off the BB services in their system, since then the dataflow is ok, and I can enjoy my Droid. No need for replacement.))
But I will keep the link for future reference.
Thanks again for the support.
Cheers
