I´m coming from CM 12. Did a downgrade to Stock JB yesterday. Since then the mobile data wont turn on anymore.
I tried: reflashing ROM, I´m having the right APN, relocked bootloader and flashed Stock via Sony PC Companion.
Had some issues in CM 12 (after stetting the Data to 2G only it wasnt possible to do a change to this) but it worked before i did the downgrade.
Any ideas?? Telephone calls works fine.

My Xperia was working fine with 3g using the official rom of sony ericsson,
but then i unlocked my bootloader and tried various custom roms but with no rom i am able to get a constant 3g connection, as soon as i switch the network to 3g and i start using browser or fb, the phone reboots.
Its strange that the phone works fine on 2g....

Does it happen on all custom roms or just certain ones?
Did you perform a factory reset in recovery before flashing between the different roms? Sometimes data from a previous rom can clash with the new one.
Alternatively you could try flashing to a modded stock rom like TEAM or EWJet and see if the problem is still the same.

I have an Xperia Mini st15i.
The problem is that the phone never shows the E,3G,H icons,
and cannot connect to mobile internet.
(via wifi it works ok).
Initially the phone had the Android 2.3.4 firmware.
The initial update to firmware 4.0.4 build 431 was done using the phone itself.
I had read somewhere that this way,
some problem might occur during the update via the phone
and this causes the 3g,etc icons not to appear
And they suggested to re-flash the phone to build 587, doing a factory reset.
That's why I have (successfully) flashed it from build 431 to ST15i_4.1.B.0.587_Unbranded.ftf using flashtool.
(I've also checked the option during the flashing, to "Reset customizations"=factory reset).
But, it didn't help
The internet settings in the device are ok, I've doublechecked them manually.
And, in Settings>About phone>Status, it shows indeed 3G.
(and generally, the 3G signal here is strong: other phones in the house, using the same or other carriers, all show 3G or Η icon all the time)
I've tried putting other SIMs (of the same or other carrier) in the phone, but didn't work.
What do you suggest?
Will it help to do a factory reset via the phone, too? (Settings>Backup & Reset>Factory data reset)
Is it enough?
Or should I do a factory reset via the phone and then re-flash build 587 ?
Do a factory reset if that wont help then repair your phone via Pc Companion or Sony Update Service
I've just re-flashed it using Sony Update Service and it was fixed.
Thanks a lot.
Hello,
So yesterday I just solved my own issue of not getting any LTE signals by reinstalling the FW.
Today, I followed the advice of a user to restart the phone using PWR + VOL UP buttons to get the smoothness back. I did just that, phone became smooth again with the phone registering on LTE network.
But what happens now? I can't connect to Mobile Data AND can't make phone calls. I can run USSD code to check my balance and can receive calls just fine but cannot make phone calls.
Any ideas? Do I need to reinstall the FW again?
Model: D6503 FW: .314
Try flashing the baseband for your firmware and see if the problem persists.

I actually tried repairing it via Sony PC Companion application on the PC but to no effect. I'm suspecting it could be a HW issue but what baffles me is that it used to work fine (apart from the LTE issue) and only after I tried repairing it yesterday did everything work correctly and wham in the morning this happened.
try to flash the latest FTF again using flash tool..and check if it can help
I connect to my router but there is no internet.
Here is the deal
I installed MIUI v5 OmniROM 4.4 (Android 4.4.2) ver 4.6.20
Everything OK, I linked my G acc, updated my apps via WIFI. After that I was outside using my mobile data connection. When I come back home I tried to connect to my wifi network and here starts the problem - connects but no internet. The mobile data is still working.
Reinstalled the ROM, wipe cache, dalvik, format everthing and still nothing.
Changed back to my old ROM efeXTREME Lite-ROM I9300UBUGNG1 (Jelly Bean 4.3) but the problem is still here. I haven't tried to connect to other network, because everyone are locked, tomorrow will try some open ones, but I don't think the router is the problem.
Reset the router first, next try full wipe of the phone then flash full stock firmware.
I just got the screen replaced after a few months it not being used. I decided to do a factory reset, and after the setup, both wifi and bluetooth doesn't seem to turn on. My MAC Address shows as 02:00:00:00:00:00. This didnt happen before I did the factory reset (I was able to connect to wifi networks).
Also, I unlocked the bootloader, but I never knew that the xperia companion app doesn't flash unlocked bootloader devices. I'm planning on flashing it back to stock (I flashed lineage).
Thanks
