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

HI ALL,
i have been facing a problem for last two days. I updated my Xperia P to JB using pc companion. It was working fine. Suddenly there was an issue in the morning the day before yesterday. It suudenly started to Reboot automatically.
First the logo of sony and xperia comes and dissolves. Then the default loading wave of xperia appears but instead of going to the lock/home screen it starts the booting process again and this process repeats.
I switched off my phone using lockkey+volume up. i tried to update/repair my phone using PC copanion and Sony Update service. Both case the latest software is downloaded and installed. But after installation when i try to switch on, it goes to the menu screen normally and asks me to select time format, language etc... but when it asks me to search for Wi-Fi networks if i touch on 'search for available networks' it falls in the same reboot loop again & the Home screen never comes..
afterwards, i skipped that step of WIFI and now it works fine.. but the problem is when i hit the WIFI it falls in the same loop. Now i am in a fix ... i dont know how to solve this and without WIFI there is just no use of this phone
the device was not rooted nor flashed before
What should i do? Try to flash my ROM?
PLZZ HELP ..THANKS IN ADVANCE

Your warranty is still intact. Take it to a service centre.

It's a long shot but have you tried to reboot your router?
Since it worked for a while, and you repaired the phone and it still exists, I am guessing it's not a problem that related only to the firmware.
Could be hardware problem.

But did you reboot it?
I had several times my phone would not be able to connect while other devices did, bithing but rebooting the router helped.
Bootloops usually come from flashing a bad rom......... Never heard of this problem before....

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.
So some time back I made a thread regarding a problem I was facing. My phone would randomly freeze up and restart on its own. I tried hard resettig, repairing using PC companion, flashing using Flashtools , changing SIMs etc. but nothing seemed to fix it. Then I had to arrive to the dreadful conclusion that it was a hardware fault. But 2 days ago I got the bright idea of flashing an older firm ware version (17.1.1.A.0.438) using flash tools without wiping internal data and now the problem is 100% fixed. the phone hasn't restarted even once after a 3 full days of heavy use. So with this I can safely say that the probem is with the 17.1.2.A.0.314 firmware. Has anyone else had this issue? because my friend also owns a z2 and his phone works just fine with the 17.1.2.A.0.314 firmware. Any ideas how to fix it?
Flash 314 fw with wiping data
I've installed the official Nougat update from Elephone using the SP flash tool. Before the update, everything on the phone was working.
After the update, the phone boots Android 7 fine, but no SIM cards are recognised.
I've tried entering Engineer Mode through the phone app to reset the IMEI (I know what they are) but the 'Connectivity' page in Engineer Mode doesn't list phone radios, only FM, Bluetooth, NFC and WiFi.
So I rooted the phone and tried entering AT commands through a terminal. But the folder /dev/radios is empty.
It's like my phone has no... well, no phone. I guess the driver is broken somehow.
Does anyone have any tips on how to proceed?

Use maui meta 3g to restore IMEI. It is mentioned several times in these forums.

Well, there's one who didn't read the question. This is not about restoring the IMEIs.
Alright. I know flashing nougat might break the radios and also IMEI. This includes not detecting simcards. I had this problem myself.....
I have the same problem, or similar .
I can sometimes send and recieve text messages and sometimes i can call. Data traffic seems to work ok.
Right now as soon as i try to make a call i lose connection to the mobile network.
Theres a simple fix, reflash 6.0, then do format all + download android 7, imei wont be restored, but both sims will be recognized and work normally

I did this and got the sim working with data and SMS but I can't call.
Should I try again? I want to restore my imei from my box too.
Flashtool and stock roms?
How did you do Tom? Did you fix it?

that seems like a hardware issue, i think theres a few cheap speakers and you could try to fix urself on ali express theres speaker at around 10$ it ahould be farelly easy to replace it
I've had this same problem, but only after replacing my screen due to damage. Ever since then, it'll see the sim but wont connect to my network.
Hi everyone,
I have a really annoying issue for a while and I hope someone can have a suggestion.
When i turn hot-spot on, my phone freezes and reboots itself, so i cannot use this feature, however if I connect it to my computer i can share my data by Bluetooth.
More annoying issue, if I try to connect to wi-fi when my data is on, it freezes and reboots again and after that I can connect, but if I disconnect somehow, it reboots again. When I turn the airplane mode on, there is not a problem..
Has anyone of you experienced such issue?
Thanks
Sounds like a corrupt system, probably network driver or baseband
SInce you don't mention anything else I suppose you're on stock ROM , still locked bootloader, no magisk and all that. Simpliest way if your not familiar with ROM and boatloader handling is probably to do a total reset to start with followed by an update. Xperia Companion can be used.
If you're famiiar with ROM handling you may get the latest ROM from XperiFirm which you flash with Newflasher

Hi pergoteborg,
Thank you a lot for your concern.
You are right, I am on stock ROM. I have tried to do a total reset, but it didn't work.
Moreover, I am living in Italy and using Tim Italia, few days ago I was in Austria and in there I did not have any problem when I connected to an Austrian operator. I tried with a different TIM sim card in Italy, it was same. I will try with a different operator as well, but I have not had time yet.
Does it pop up anything on your mind about what could cause such a strange problem?
Thanks in advance.
Regards
