[Q] SIM-card(s) not readable

I've got a more or less big problem. My Xperia SP cannot recognize, that my SIM-card is inserted. If I turn it on it doesn't ask for the PIN and furthermore I can't receive or send SMS's, I can't receive calls or call somebody and I haven't got mobile data. I tried to insert my SIM-card in another sony phone and it didn't work. I also put another working SIM-card in my phone and it also couldn't recognize it. I think (I'm actually sure) it's caused by the non-functional phone apk, but maybe also the SIM-card is broken.
What shall I do? I have a TWRP backup, but I'm not 100% sure, whether it is from before or after. What is a less- or non-risky possibility to replace the phone.apkor is there a better method to repair the phone?

edit: I found out, if my phone is turned on and I remove the SIM-card, it realizes it, and reboots.

Please help me!

Sorry, but why is my post ticked with a hook??? The problem isn't solved yet!

Get a new sim card.. This will fix most simcard issues

First of All thanks for your reply. But I already took another SIM-card (which on Xperia L works fine) and put it into my device but there were the same problems. Yesterday I downloaded the SemcPhone.apk file, pushed it to /system/app and changed permissions to rw-r--r-- and rebooted. Then it asked for the PIN but after unlocking I got a bunch of Force closes and they didn't stop.. Even after rebooting again I had the problem, so I deleted the apk file again. But it's now the same like I described there above :/

Reflash ROM.. You have phone.apk problems aswell so this should fix it

Okay.. And the stock ROM, is this the "Deodexed stock ROM" (777MB) from android development or the "normal" stock ROM (odexed) (12.0.A.2.245) also from android development section?

No, to prevent any issues just open Sony Update Service (can be downloaded from the Sony website) and "restore" your phone..
So go back to full stock

Okay cool thank you I'll try it

The last version of Sony Update Service misses the XSP.
I have contacted Sony Mobile to point this out. Untill we recieve a new update you need to use the PC Companion to restore your phone or you need to use Flashtool

Okay, then I'll do that

:/
I tried it with PC Companion but when it had to start repairing and it booted the phone into flashmode (I think so, because the LED was green) and then PC Companion said: "The phone contains modified software, which cannot be updated" and below "Error 2003" ..
I tried it 2 times and both the same :/
My phone has unlocked bootloader, is rooted, and has the DoomKernel, no custom rom.

Well that is unfortunate. You need to relock bootloader and reflash with flashtool.
You cannot use Sony software with unlocked bootloader

Oh! That's actually bad. But then I first have to flash back the stock kernel, then relock bootloader, repair with PC Companion and eventually unlock Bootloader again if necessary for me, right? Just for being sure.

Yes correct you need stock kernel then lock bootloader,then re flash/repair phone
Sent from my C5303 using Tapatalk

Ok good. Now the last question: from where can I get the right stock kernel? I found a post from DoomLoRD, where he wrote, that you have to flash stock kernel.sin and no FTF kernel but I couldn't find a stock kernel.sin and in another post from alivanov79, alivanov79 posted a link to an FTF kernel. So Do you know which one is the right one?

Hello! I hope you're still alive!
I am facing the same problem, but before I start doing stuff, may I know if your problem has been solved?
My Xperia SP as well on occassion doesn't detected sim card. Sometimes when I need to make phone calls the most, it starts to do it. I am planning to send it for warranty, as I am having another 20 days before the warranty expires.
Surprisingly, many Sony Xperia models users have experience of having a phone that doesn't read SIM cards. Google reveals it all.

Hey,
yeah, I'm still alive
So, the thing is, my problem there had been caused by myself, fiddling around with some root stuff, so it hadn't been my phone's fault.
But what I did is I just flashed another ROM because I didn't see another solution and it really drove me crazy not being able to use the SIM card related functions.
Well, keeping your post in mind I don't think you'd like to flash another ROM (I probably shouldn't have done that, too).
So if you didn't already try to repair your phone with PC Companion, that'd be the first thing, I'd do in your case.
Otherwise I'd send it for warranty as you considered it already.
Yeah, my sister's Xperia L also has that problem and that's really unfortunate.
So I hope, my "advide" could help at least a bit although there may not be plenty of hints, but yeah.
If I shocked you with that essay I'm sorry, too

Lol I don't think ROM flashing is the root problem, as I have been using CM11 for a month (and maybe more). The problem starts appearing lately..
I will flash stock ROM and relock bootloader and then reflash stock via PCC to see if it will fix the problem
Anyway thanks for the reply!
No, that's not even something to be called "essay"....

Xperia T - Not possible to turn on Wifi after Updating to Android 4.3

Yesterday I updated my Xperia T to Android 4.3 via Sony Companion Software. My phone is not rooted. Everything apperently went fine, but after the Update process I wanted to turn on my Wifi, but it did not work. I tried that from the quicksettings and form the settings directly. The button remain grey for a certain time and the turns back to off.
I turned off my phnone and on again, but a white triangle with a screw came and the phone remained in that status for more than 6 hours. After that it turned on, but the Wifi problem remains. Regarding Bluetooth, that works fine.
What I noticed is that when I check the phone info and the Wifii settings, no MAC Adress is listed there for Wifi. I don't think its a hardware problem, because everything was fine before updating.
What should I do? I am afraid to turn my phone off bcause it could go back to the white triangle remaining for several hours in that state. I dont think a factory reset would help, because there seems to be an update problem and I would like to rather not loose all my settings.
Any help would be very appreciated, because I urgently need wifi in my university.......

The ftf file is the stock Rom, you can find it here on xda. Flashtool also. Flashtool only works if you have windows xp, vista 7 or 8. Not on 8.1. Repairing it using pcc should be easier though

I updated to Android 4.3 on a Windows 8.1 PC. Do you think that might be a reason, why there is an issue with the update process or something went wrong?

Unfortunately, reparing it with PCC did not help and I am quite desperate. I bought the phone last year as a used one. I am quite a newbie in this field, but could it be, that the rom installed is an altered one and a normal update via PPC leads to this Wifi problem? Normally that should not be the case, but how can I find that out what is causing the problem and what must I do to overcome this drama of mine. I whish I didn't perform that update, because everything wAs working fine before.....

Bluetooth conflict with wifi
I just upgraded to the latest build 9.2.A.1.205 and bluetooth and WiFi seem to conflict with one another. To have Wifi working i have to stop Bluetooth.

A factory reset would definitely work. You don't know how many times I've seen people (even with different phones) have problems like these because they change their Android version and/or flash different ROMs without wiping their partitions, i.e., doing at least a Factory Reset. If you were rooted you could try deleting the "wpa_supplicant.conf" file in /data/misc/wifi. The problem is, since you're already on 4.3, there is no sure way to root 4.3 unless your bootloader is unlocked. So unless you find out a way to backup your data/settings, you're either going to lose it all when doing a Factory Reset, or downgrading to 4.1.2 (to root), or even flashing a stock 4.3 FTF, because I'm sure your problem is that you haven't wiped.

Fasching Kernel + Baseband only - Phone dead!

Hi
i had paranoid android installed but the baseband was the wrong one..
(I installed iHackers 4.1 without flashing kernel + baseband because then i landed in a bootloop)
When on ihackers i installed paranoid android 4.4.4 over it and it worked. But also like in ihackers
i could not connect to my network because of the wrong baseband.
So i downloaded C6903_14.4.A.0.108_Generic_DE.ftf and flashed only the baseband without wiping anything..
Restarted .. baseband hasn't changed but the system booted and everything was fine.
Than i flashed only the kernel and the baseband without flashing anything else and wiping anything.
The phone went dead. Really dead. Power + vol+ which allways worked (3xvibrate) not working.
LED not working .. Just dead!!! i have it on the charger because before the last flashing it was @ about 15 - 20 % accu.
But even when i connect the charger .. no led .. nothing .. its playing dead.
Any Idea? (it is .. now that i remember .. not the first time a z1 went that dead on me.. I had a z1 before which did the same. now in retrospective I remember flashing kernel and baseband (ONLY) also on that phone.. and it went dead.
If somebody likes to trash his/her z1 try flashing only baseband and kernel. (I am sure the kernel and the baseband are the correct one for the firmware.)
Any ideas how to reanimate my z1?

You have flashed a stock kernel to a custom rom, so of course you will get a bootloop.
Solution, flash a stock FTF, after leaving the phone on charge for a few hours
and post your questions in the Q&A section

Cant get into flashmode or fastboot mode.. it does not react on any button combination

This happened to me when I first got my Z1. Unfortunately I had to send my phone back to Sony which they ended up replacing the motherboard.
They won't be able to detect any custom firmwares. Waiting time is unfortunately about 14 business days once they receive it...
If you phone is unlocked be sure to let them know so you get an nck unlock code. You will have a new imei.

This is not a motherboard issue, it just needs charging for a few hours and then reflashing. Also he has lost his warranty due to unlocking so since this happened as a direct result of flashing custom roms he wont e able to claim on warranty

I understand this is not a motherboard issue, however the exact same problem happened to me months ago. Even after waiting overnight and trying to enter flash mode again it would not respond properly.
Sony's solution is to replace the motherboard at the repair facility I'm assuming because it is the easiest method.
I can almost guarantee this is what will happen when you send it in and they won't deny you warranty.
If you cannot get your phone into flash mode after a few hours, try again overnight. If not I would send it in, or get your carrier to replace it.
Repeat this magic phrase: "I updated my phone and it wouldn't turn on"

Hi,
I've run pac-rom on my Z1. Now I want to flash from the current .109 firmware only the base band. In Flash Tool under exclude everything except I labeled baseband. Then the flash process starts without error message. When I start the phone is still the old baseband version. What am I doing wrong?

Maybe its the same baseband?

No,
old version is .39, and the new from .108 is .51

Hey thanks for your answers @ all!!
The failure was that i flashed roms / ftf with very low battery. Than i charged for a few hours and flashed again .. and on and on.
At some point the accu seems to got broken.
I send it to a repair facility used by sony and they confirmed that the accu is dead.
It seems that i get a replacement. (on warranty)
Thank you again. ! SO!!! What we learn from this is "Only flash your device when its charged!"

Zony Z1 C6902 No signal

Hey guys. I got this problem:
One day in the morning the cellphone lost signal and never got it back. As i believed it was a software issue (coz the cellphone was on and suddenly signal dissapeared) i tried to flash a ROM and do a lot of stuff. In Venezuela we have no Sony Center. At the end my cellphone finished with CM11 and no IMEI. If u have any solution for this, I'll be really grateful. Thanks in advance for ur time.

Try wiping all data and flashing a full FTF using flashtool, if that doesnt work,then im afraid u r gonna have to get a new phone:good:
How many roms have you flashed anyway?
Provide some more detailed info about how and when this happened.does the phone detect the sim card?
Does the stock sony rom by any chance go on a reboot loop when starting ,because that happened to me when my old xperia z's baseband died:angel:
Good Luck,I hope you fix your phone quickly

Thanks for writting. It started suddenly, i though it was an update. I've flashed like 4 ROMS (dont remember which ones tho). The cellphone detects SIM Card but cant register to any network. When I installed other ROMS it got on a reboot loop. I also think maybe i have to get a new phone and use this one as a mini tablet. Once again, thanks for leaving an answer

When I installed other ROMS it got on a reboot loop. I also think maybe i have to get a new phone and use this one as a mini tablet. Once again, thanks for leaving an answer
