[Q] Xperia Z 6603, 10.3.1.A.0.244/ 10.3.1.A.2.67 - mobile data problem

Hello All,
I am afraid this not is going to be a short and easy story... I will try to be short
After the Stock update to 4.4.2 i got finally fed up with the fact that the long awaited KitKat drains battery like a power addict and decided to go back to stock 4.2.2 - which, for me, solves two problems - in this version the Bluetooth connectivity in my car works properly and the battery is used more 'soberly' as well as that I can easily root it and clear all the bloatware.
I found several stock versions of 4.2.2 - e.g. C6603_10.3.1.A.0.244_Generic NCB.ftf, C6603_10.3.1.A.0.244_CE.ftf, C6603_10.3.1.A.2.67_CE.ftf
After flashing them with the latest flashtool everything seems fine - battery, bluetooth,wifi etc. BUT the mobile data has the following problem: the phone connects to 4G, 3G and GPRS, but apart from Youtube none of the applications is able to use the Internet connection from the mobile operator. This to me seems like a problem with DNS resolution but I do not have any firewalls etc. installed or activated.
It may be worth mentioning that when Chrome tries to connect to a web address (e.g. xyz) for an instant there is a message on the screen "Redirecting you to xyz web address", maybe this is the place where it goes wrong? Needles to say that the connection to the specified website is not possible because "Chrome could not find the xyz page"... (this does not happen on wifi connection).
I would be very grateful if U could suggest a way out !

Have you tried downloading the Internet setting ?
at setting -> xperia -> Internet setting.

Hi,
I reloaded the Internet settings from my operator several times, also changed to another sim. What is really puzzling is that Youtube has no problem with connecting. There is something funny going on with the DNS service I suppose....
Any thoughts ?
Thx

Hello - thanks for this attempt, but unfortunately no luck with it. Here is what I did (please check if I understood you correclty):
1) downloaded - C6603_10.4.1.B.0.101_CE.ftf (4.3)
2) flashed 4.3.(above) with Flashtool (wiping all)
3) restarted - mobile data could be accessed by Chrome and other apps
4) flashed 4.2.2 ver 10.3.1.A.0.244 and then 10.3.1.A.2.67 with the data wipe disabled,
Result - again in 4.2.2 the mobile data is not available to apps other than Youtube ...
Any more thoughts on this?
Thanks again !

Another solution will be root the 4.2.2 using easyroot
flash prerooted 4.4.2
download no frills cpu from playstore and under-clock the processor a bit it will greatly improve battery life.I am doing the same :good:

OK - So I see where we have a misunderstanding ... I wanted to go back to 4.2.2. which worked fine for me for the small exception of the mobile data transmission but not go up to 4.4.2.
I am looking for a solution to make the 4.2.2. work with data transmission.
Could you give this a thought ? I would appreciate it a lot!
Regards!

I gave 4.4.2 solution because the data issue is sufficing in 4.2.2 repeatedly
and from what i had read the only issue you had with 4.4.2 was battery drain so gave you a solution for 4.4.2 :silly:

Your help is very much appreciated!
The reason I keep trying with 4.2.2 is that I am also struggling with the bluetooth issue: on anything above 4.2.2. - simply does not connect to my car's buletooth handsfree....
Thanks anyway. I need to decide whether I have the bluetooth and no mobile data or mobile data and no bluetooth, Seems like Sony is not too generous ...

Yes:
4.3 - mobile data is ok, bluetooth not compatible with my car ... :crying:
When I tried to flash 4.2.2. over 4.3 without wiping data I got bootloped...
Thanks for trying to help !
Do you think that there is a way to use the bluetooth functionality from 4.2.2 on 4.3? How could it be done?

Maybe you can try flashing the 4.2.2 via flashtool (wipe everything) to solve this problem, please give it try.
Actually, 4.3 works without bugs so far and have no thoughts about what causes this problem.

Hello - thanks! I tried complete wipe/flash of 4.2.2 and that's where my problem is - 4.2.2 data transmission in mobile is lost whereas on 4.3 or above my bluetooth does not communicate with my car's handsfree (this issue is being reported by many users after upgrade to 4.3.)
So I am stuck ... for the moment I am staying on 4.3 and getting really tired of this whole Xperia stuff

Hello barbacan! I've got exactly the same situation here. I was on 4.2.2 becouse it was latest firmware that worked with my car (Opel Insignia DVD800). A week ago I had motherboard failure, so I send my phone for a replacement. I received a brand new one with 4.4.2 installed which of course didn't communicate with my car. So I flashed exactly the same 4.2.2 file which I use with previous phone, but this time data transmission did not work. When I upgraded to 4.4.2 transmission was back again. I think Sony have changed something in newer phones hardware and they are not compatible with older firmwares. I've been serching for a few days, but couldn't find any solution...

Ok, I think I have found the solution. Changing APN settings from default IPv6 to IPv4 resolved the issue for me. Just change it in settings, save, reboot the phone and data transfer works again!

THANKS A LOT!
This is the solution.
I was suspecting something to do with DNS services but did not realize that Adroid 4.2.2. does not have IPV6 support. Now that I changed my APN from "InternetIPV6" to plain "Internet" the phone works like a charm. I will not be tempted to upgrade at any price

[Q] Tethering Problem

Hey guys,
I have a Z1 C903, which doesn't work as a wifi tether nor bluetooth tether. I can turn it on, and other devices can see it, however when trying to connect, the signal drops completely.
If I wait the signal will restart and become full strength, where I will need to manually connect, which proceeds to the signal disappearing again. I've tried unsecure, wpa2, wpa to which I have no luck either. Devices such as laptop will say limited connection, whereas android tablets and phones will refuse to connect and will say "Saved, secured with WPA2" or something else if i change the password method.
I've tried searching for any reports of wifi tethering not working, but the problems seem to be different from my situation.
More details on my device:
It has an unlocked bootloader
Now running Paranoid android
Problem occurred on stock 4.3, nut 4.4 (I assumed it was a glitch on Sony's drivers, and have waited for months now for a patch)
Could a faulty TA do this?
Any ideas?
Am I f***ed?
Cheers

Flash your phone by flash tools including wipe apps log and cache and system
It should solve your problem
And of course first re-lock your BL and flash to stock Rom

Sorry about late reply, I am out in urban areas without internet connection. I'll try doing this tonight.
Am I right in assuming all Z1 CM ROMs have this problem, if I must install a stock-based ROM?

Oh, sorry I forgot to tell you
You should use stock rom
http://forum.xda-developers.com/showthread.php?t=2469191&page=145
Go here and fun your phone model and download the version and region you want

You can try to change the name of your phone (Network SSID) to a simpler form instead of default.

I got it working
I got it working thanks to your suggestion, Saeed.
I flashed the stock ftf from the mega thread and that restored my tethering capabilities. I then proceeded to reinstall the ParanoidRom and now the tethering works as well.
I'm not sure what happened, but I'd assume something went wrong when upgrading to 4.3 and the problem stayed when I then upgraded again to 4.4 and then to paranoid.
Thanks

Trouble on wifi. Will this fix it?

Hi. So, I just got a Samsung S3 GT-I9305 from Vodacom. Got it from eBay. But, I'm having trouble connecting to the wifi. Whenever I connect to the wifi it always says "Authentication error occurred". I turned off the wifi thingy using *#0011# and wiped the cache, I even reset the phone to its factory settings. I sometimes connect to a wifi, but it takes 1 hour or so before being connected. And I have trouble downloading from the playstore. Did everything I could find from the web. No luck.
So, I was thinking, If I would flash a custom rom to my device, will it fix the wifi issue? And would any stock firmware of the I9305 device work?
Thanks! Sorry for being noob.

Hi,
I think it could be a router issue. You should :
- reset your router and retry to connect with your i9305,
- play with WIFI network settings in router. Maybe something doesn't allow your i9305 connection (network type, firewall, etc.). I'm not an expert in router settings, so you could google this to help you.
- try another WIFI network (from a friend, at work, anywhere you can test )
I think that flashing a custom ROM won't change anything. First try to fix your problem with stock firmware.

[HELP] Wi-Fi problem after mm update- SM_9208

My note 5 is the duos version, imported in Romania from Taiwan (SM_9208) After updating to Marshmallow yesterday, everything worked fine except for on thing: it doesn't find my Wi-Fi network from home anymore and the only way I can connect to it is by going to,, add network " and manually inserting the ssid and PASSWORD because it doesn't appear on the available networks list. Thst means that every time I turn my wireless off and then on, I have to repeat that process.
I haven't had the chance to try any other WiFi network, but I tried with other phones to connect to the network and they found it and connected to it without any problem. Furthermore, any third party app like WiFi analyser is able to see the network.
Do you guys have any idea how I could possibly solve this?
Thank you and have a wonderful day!

Try to backup your phone and then do a factory reset.

I factory reset after update OTA and everything work perfect.

uhm... does n9208 has update for MM already? if you have links kindly share tnx in advance

I tried doing the factory reset and it still has that problem.
And I did receive the update yesterday through OTA.
Other suggestions? Thank you, guys!

First, try clearing the cache again. If it still does not work, the update may have downloaded improperly so some file are corrupted. It will continue to use the same corrupted files even if you reset. Have your tried flashing the stock Taiwan Rom using Odin?

//LATER EDIT: I finally made it work by simply changing the wireless network's name. For some reason, my phone wouldn't find the network with its default name.

OnePlus 3t Bluetooth not turning on

Hi guys I really need some help. It's been quite a few days now since my Bluetooth isn't turning on. I've tried clearing cache n data for Bluetooth apps and services in application manager but still no luck. This is what happens when I try to turn on Bluetooth... (Check screenshot)
The switch just fades and Bluetooth doesn't really turn on at all. And after a while the switch turns off by itself. Please help.
I also tried flashing another kernel (from stock) but still no luck. I'm on OOS 4.1.7 with Blu spark r174.

It had stopped working since I was on stock OOS (non rooted) and then I rooted and installed Blu spark but still no luck.

I have tried clearing app cache and data of Bluetooth share app, reset network settings even tried factory reset, still no luck. OOS 4.1.7.
Someone please help.

If it isn't working after factory reset, most probably it is a hardware problem..
Another issue that I've heard off is related to the encryption of the storage, but i don't think this is the case now

But then the system acts weird about Bluetooth. When I try to turn it on (notice I do get an option to turn it on), the switch flips on the other side (switching ON) but fades n does nothing. And if I move out of settings and come back to Bluetooth section, it goes back to off. I kind of have a feeling it's a software problem n just needs some system modifications. But I really don't know, really need some expert opinions, please help guys.

Full wipe and try to downgrade to earlier OOS version..
( 4.1.5 ) or try another custom kernel ..EX or Dorimanx....

This happened to my dad on another phone and after a while the wifi died as well. It's a hardware issue.

I had the same issue 2 months ago. tried to switch back to stock and everything, it did not work. So I sent mine back to Oneplus, it was a hardware problem and the motherboard had to be changed. It sounds like you are unlucky as I was.

Just dirty flash your Rom and check if it works.

When folks say "factory reset" they most usually means just using the option "factory reset" in stock/custom recovery, or in phone Settings. All those do, is wipe user data. SO the problem will only be solved if some problem/incompatibility with user data was the culprit (does not actually "restore" any software/firmware).
I would suggest flashing the full 4.1.7 (or even early version) zip to restore to full stock, which I think is more what you meant.

This has happened to me before after updating magisk and not re-flashing a kernel. Wi-Fi and Bluetooth weren't toggleable (if that's a word) and the phones battery was draining pretty aggressively. I'd follow the advice from others and do a reset, or flash a custom kernel over what you have.
