I have a Sony Xperia Z2 tablet. I've had it for a couple years I think. I used it only as a wifi device even though it could take a SIM. It's an unlocked Verizon tablet.
When I go to search for Android Updates, I run into errors.
On wifi, I get "Error during DM session."
With my new T-Mobile SIM and mobile data, I get "Network is not available." And yet I can use the internet. In fact, I'm using Mobile Data as I type this right now. So the web works. Why doesn't the update?
Is there any way I can get this to update short of rooting it?
Present Android is version 4.4.2. What other info would you need to know?

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
Hi there,
have you tried changing your network mode in mobille network settings?
I tried the kitkat update and had mobile data availiable in germany.
Next question would be, is your device locked or unlocked? If you have an unlocked device you could simply downgrade as I did.
Best regards
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
Urb
Please do the following so I can be sure if you are locked or unlocked:
1.) Power off your phone
2.) Power on your phone by pressing the power button and the volume up button simultaneously - you should be in a menu
3.) Press the volume down key twice and then once up
Now you are in the AP fastboot-mode. There you should find someting like "Device Status". It will read either locked or unlocked with a number.
If you are locked the only option you have is to stick on that firmware, but as far as I know you can reflash the entire kitkat update.

Follow this step by step.Please read carefully and double check every step.
Best regards
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.
Cheers

I hope you can get it to work properly again :thumbup:

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

Glad to hear that everything is working fine now.
Enjoy your Droid

I've got a Z3 Dual 6633 and the device notifies me of a firmware update where it is necessary to connect the device to the computer to update the system software. This has happenedd twice in the last month, and I go through the process on the PC, however the resulting firmware version is exactly the same. - 23.0.F.1.74
As per Sony's website, the latest firmware version is correct, but the release date was 22-SEP-2014:
http://www.sonymobile.com/global-en/software/phones/xperia-z3-dual/
Is anyone else experiencing the same with their Z3?
Any insight is truly appreciated.
Got same message this morning over mail.
My update center doesn't show me anything.

Ironically when I connected my phone to the update center on both the PC and MAC, it ran through the update process normally. But as stated before, the software version after the update remained unchanged...
Yes I too experienced exactly the same twice. No noticeable change in version after the update process.
Me too face same,and i update my phone both times..
On a positive note at least they have confirmed through the page that the dual will definitely get android 5.0 lollipop..

Hello. My xperia m2 says that there are no updates and the phone is up to date but it's with android 4.4.2. Theres 1 secound delay in the sound when I play games or use downloaded apps like youtube also the audio doesn't sound very good. To fix that I need to update the android version but I cant. I connected the phone to my computer and updated it with sony PC companion but the version is still 4.4.2. What should I do? I don't want to use flashtools or anything. I think it's the phone's fault for that and I should give it back to the place where I bought it so they can fix that. The phone is brand new and they already changed my camera because it wasn't working. So what should I do?
I suppose it has to do with the Country of your phone and/or if it is branded. IF after using PC Companion it's still with 4.4.2 I'm afraid your best (and only) option is to use Flashtool. Not sure how it works if it is branded though, you may need to to something to be able to de-brand it.
Well, actually try first to check if 4.4.4 is available in this way:
- Dial *#*#7378423#*#* (*#*#service#*#*)
- Check the number in Service Info/SW Info/Customization version. You just need the xxxx-yyyy part
- Downdload and install Flashtool (it's small. You just need it for checking)
- Run Flashtool
- Go to Devices/Check Updates
- Select your phone double clicking on the id xxxx-yyyy you have got before.
- If the version is 18.3.C (like the one for 3 UK) there is no 4.4.4. the latest ROM is 4.4.2. It must be 18.3.1.C for 4.4.4
My is branded from T-mobile, and i flashed CE ftf to debrande, everything is good except i don't have extra apps that T-mobile puts in. As i know your safe flashing ftf cos it's official Sony's software, just using Flashtool instead of PC Companion and you won't lose warranty, as long as you don't unlock bootloader.
Good Luck.
Xperia M2 D2303 on K.K. 4.4.4
Do I install the flashtool on my computer or on my phone?

Obviously on the computer. It's needed to flash the phones from it. Just google it, you find it immediately. Then if you decide to flash a generic 4.4.4 FTF just search around. There are dozens of guides in the Internet.
Alright thanks for your support guys
Hi guys I have a Sony Xperia Z3 I had to have a new battery installed so I got it done had my sim card and memory card removed. When I got my phone back it had kitkat 4.4.4 installed which I thought was strange as I had lollipop installed onit before hand. I have tried the sony pc companion repair option and still its on kitkat the sony software is saying its upto date? Now here's the strange part I have no access to google services it doesn't exist on my phone anymore and neither does google chrome! Im really confused I can still get onto my google account online via pc just not on my z3 can anybody please help as my phone seems pretty much useless now as everything was backed up to google. Any help would be much appreciated. Thanks.
Im in japan. my phone doesn't show ota for marshmallow, only for Sony bloatware. and pc companion on Mac says yes there is an update available... But then after about ten seconds the dialog box is replaced saying that I am running latest version available (though i have 5).
Same results when I tried VPN.
My phone is unlocked as originally purchased. I have a data sim.
Does it refuse because I have only 500mb on internal? There is no error message-it just changes its mind.
Any ideas? Just wait?

There is actually a mac version of Flashtool, but maybe not xpirifirm so you might have to find a pre-made FTF.
I guess you don't have root?
Update manually with Flashtool? Lots of guides available. Might not even have to make your own FTF file, but I recommend doing so if you can as then you know what is in it.
Essentially this is the same as using Sony software to do it, but you have more manual options. Download the files with xpirifirm, decrypt them with flashtool (not as complicated as it sounds), then it will make an ftf file for you which is the bit that contains all the system for the phone / update, then follow instructions to flash it onto the phone.
I'll look for a decent guide link.
My top tip is to make sure the TA partition stuff is excluded when you select what components to add to the ftf file to be safe, but flashtool should exclude this by default. And to make sure you download the software for your exact device so double check it when you choose
It really isn't as overwhelming as it may seem when you first look at it.
How to make the ftf: http://www.xperiablog.net/2014/08/1...re-files-using-xperifirm-and-flashtool-guide/
How to flash it: http://forum.xda-developers.com/showthread.php?t=2697277
(Just ignore the parts telling you to download anything in the flashing guide as you got it from the "how to make" and obviously just replace that phone and firmware with your own)
Thanks. I have rooted and flashed a couple other phones but not Sony. I guess I would do that if it came down to it, but it shouldn't be necessary. With the z3 don't see the payoff for the risk. I can live with the bloatware.
More to the point this update should just work! Why isn't it?
If I use PC companion doesn't that get the update straight from Sony regardless of carrier? (I have no carrier, just a 3 month data sim)

If I helped hit thanks
Something along the way is causing the problem. Tried reinstalling PC companion?
I say manual flash because that eliminates the variable that it's your phone causing the problem and also gets you updated as you wanted soooooo two birds with one stone
If you can't so it by PC I hope the phone eventually sorts itself out
Did you use xperia companion? If you used that, then there might be no update available yet for your phone, because xperia companion have a bug that shows an update is available, but there really is no update available.
Yes I'm using xperia companion. I guess I'm experiencing that bug you mention.
How can I establish if an update is available when I have no carrier? If I have no carrier then is it still dependant on the country I'm in? I know others have received the update for d6653 in other countries.
