[Q] Mobile network crisis after flash - Xperia SP Q&A, Help & Troubleshooting

So, I'm having some issues regarding my recently flashed XSP C5302.
Model: C5302
Android Version: 4.3
Baseband version: 8960A-AAAAATAZQ-40031007-18
Build number: 12.1.A.1.201
I'm on locked BL.
Thing is, I flashed it as soon as I got my hands on it due to that annoying flickering screen, tried to downgrade it to 4.2.1. It was the first time I did that, so I went through many tuts to get it right.
At first I flashed a .254 rom, and when I entered the About screen, model had switched to C5303. What I did was follow DoomLord's guide to root it, instal CWR and flashed a deodexed .254 rom for C5302(this one: http://forum.xda-developers.com/showthread.php?t=2423625). Everything back to normal.
But then I noticed my mobile data wasn't working, so I thought it may have been fault of the deodexed rom. Sooo, I upgraded it AGAIN to 4.3 using PC Companion, just to find out that the mobile issue was not having the APN correctly configured. Sigh.
And well, I'm now stuck again on 4.3, but at least my mobile data package is working. However, it's extremely slow. I mean, I can see the H and H+ icon, but even on H+ it takes ages to send messages and connect. At first I wondered if the baseband had anything to do with it, but when I flashed the rom I checked everything but Kernel and System, so...
So my question is, is it possible that I did something that "damaged" my mobile data connectivity? If so, could somebody please suggest any solution? I must say, my service provider sucks, so it could be their problem too, and I'm just here crying over spilled milk with no reason at all.
Thanks in advance!

Probably your service provider - I must have tried 100's of custom roms and whilst some have meant that data didn't work, this was caused by buggy software, never damage to the phone.

dead NFC and rear led on all roms

hey,
I had 4.2.2 in my 5503. Couple days ago I decided to upgrade it to 4.3 using flashtool, because there wasn't official 4.3 for my region yet . After that, I noticed my led and NFC are dead. Led isn't working (no flash when making pics, not working as a flashight). NFC unchecks just after when I click on it. Tried: downgrade, delete/rename usf (like in xperia z), many others official roms. tried fix and upgrade by SUS and SPCC. No changes. Also tried CM11 4.4, but still led is dead, NFC option can't be even marked. Now I'm on rooted 4.3. Any ideas how to bring them back? And no, backup doesn't exist
waw that's not cool.. do you erase the whole system when you flash?

Yes. I thought it is better to have clean instal. Habit of installing roms on old phone. Everything else seems to work fine. I'm out of ideas.
hmm it's weird dude. well I suggest :
ensure that you bootloader is locked
do a fresh full flash with all wipes
do a reset in settings > backup & reset
then go into service menu > service tests > flash led
for the service menu, at the stock dialer, type : *#*#7378423#*#*
if it still doesn't work after this, I'm afraid this is hardware related.

Did that many times. To have clear conscience I connected phone to another usb. formated, flashed .67 with wipes. After reset, in service menu led is still dead. connected to pc, updated with SUS to .569. and same story. I'm sure they were working before 1st flash and upgrade. If this is hardware problem, should NFC unchecks itself just after I click on it?
Ehh I suppose, I have to deal with it. There is no cure for my zr
ps. in /system/app/ I can see ncf.apk & nfc.odex only. That's it, right?
well I don't know mate, did you ever unlocked the BL? It may be drm related also

NFC firmware needs update?
I got my ZR a few weeks ago, it came with 4.1.2 on it.
Straight away I hooked it up to PC companion and it updated to 4.2.2, during the first reboot I got a message on the screen for quite a while: "Updating NFC firmware"
I then had problems and thought it was due to 4.2.2, I downloaded & flashed a 4.1.2 ROM, once again, on the first reboot I got the "Updating NFC firmware" message.
Then I realized that the problems weren't due to 4.1.2 and flashed 4.2.2 again, once again got the "Updating NFC firmware" message.
This might not be much use to you but it seems to me that the NFC firmware needs to match the version of Android you're running.
Sorry, no idea how to update it manually, just thought it's something you might like to investigate.
Maybe start here ....
http://forum.xda-developers.com/showthread.php?t=2284166
Ilko, yes. BL was unlocked. I had thought, drm can be involved with it. If yes, I'm pretty ***. I don't see any other explanation. many official roms. repairs by sus and companion. checked in buildprop editor, and everything looks ok.
alan573819, when I bought mine it was 4.1.2 also. Couple weeks later upgrated it to 4.2.2. but I don't remember that NFC dialog. I just don't remember, so it doesn't mean I never had it it was long time ago. I know that topic. Believe me, I know them all I'm silent reader xda since se k800i. Always found answers without asking. Until now.. I had to register, because no1 have same problem. with z, there is problem only with NFC (no1 complains about led), and they can fix it by deleting usf. It doesn't work for me. anyway, on 4.2.2 I had no problems with NFC or led. everything worked perfect until I decided to upgrade it to 4.3 with flashtool.
my phone was unlocked, rooted, had .310, .67, .569 for at least 3 different regions, had CM11 4.4, was repaired and upgraded by SUS and Companion. No changes. It just has to have something with drm, because I don't believe that hardware was broken during update. drm can explain it. but.. that's weird if NFC and especially led has something to do with it.
okay, then did your ever relocked it? backed up TA? restored it?
Made in ZR
yes, I have relocked zr.
Like I said before, I didn't make any backups. Didn't expect any problems so I just wiped and flashed my phone. On the other hand- who expects them? . I can risk with my own phone. If I do something for others, I always do backups, double checks etc.

[Q] No Service/No contacts?

So this is my first time rooting/flashing so I'm not a pro at what I'm doing but I wanted to give it a try
Anyway, so I rooted my S3 Mini with Unified Android Toolkit and backed up apps etc. Then installed CyanogenMod on my phone. Everything is okay except for 2 issues.
1) I haven't got any SIM Contacts, were these deleted when I wiped the phone and now I can't do anything about it?
2) I see 'No Service' on my phone when I bring the toolbar down from the top of the screen. See this is weird because I have service and am using the internet, but I don't actually have a registered network. I went to network providers, scanned and tapped my network, but even then, there was no change. I am running a UK S3 Mini on baseband ...XXAMJ2 and Installed Jellybean 4.1.2 (CyanogenMod 10) 20130727 from Maclaw'NovaFusion
When I rooted with the Toolkit, I chose the option [Up to ALL7] if that makes any difference?
Is there any way I can see which network I'm running because I'm confused and was gonna just flash the stock rom and unroot...
Thank you
P.S Also just checked in About Phone and my Network/Service Status comes up there, and my mobile data works, but it still says No Service when I bring the top toolbar down?!

For the SIM contacts: Try to pop in you SIM to an old phone and check if the contacts are still there, if yes good, if no... my condolences.
I strongly recommend to switch to CM11, it's working just fine, with no major bugs or problems. Well, i'm using it and i'm very picky when it comes to bugs and other issues.
The point is, you have to re-flash you phone anyway and along the way, you can update to a better android version.

With switching to CM11... I'm currently on 10 because my S3 was running 4.1.2 originally, if I were to flash the 4.4.2 rom, would it work and be compatible? Sorry if it seems like a basic question, I'm not really that knowledgeable about this
EDIT: Just did this, worked wonders! Thank you!

[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

[I9295] Cellular not working

Hey guys,
in the beginning, sorry for my bad english (native german). I have a problem with my I9295 aka S4 Active. Since the update to 4.4.2, my phone gets thrown out of the network. Wlan and Bluetooth is fine. Now I flashed the official Samsung DOB4 firmware. Yes, I've downloaded the file multiple times, and the md5 sum was always right. After I flashed it, I was very happy because my cellular network was working again, I could make some calls, etc. But after 20 minutes, it started again. No network. Well, my IMEI was null, and to fix it I had to root. After rooting, my IMEI is there again (yes, the right one) and everything worked fine and was still working, up to yesterday. IMEI still there, baseband too, everything seems fine, but I can't get network. I have to reboot multiple times to get it working again, after that it's working maximum a day, after that, no network again . Atm, i've flashed CM12, but the error is still occuring. I'm very desperate, I hope somebody can help me.
I have a quite similar problem:
My I9295 loses service randomly. Happens quite often.
When I try to go to Settings/More Networks/Mobile Networks I am told "No SIM ..."
SIM is in and had been active. Phono tells me I have network reception.
After reboot it works for an hour or 20 minutes or whatever it wants to.
Sometimes it reconnects after a while, sometimes not.
When I leave it on during night netx morning reconnect works only via reboot.
SIM reader had been replaced.
Problem persists with genuine 5.0.1, with this one: [ROM][Official Nightly CM12/Unofficial CM12.1][5.0/5.1.1] builds for I9295
and WizCyan ROM.
Any suggestions?
BTW I use a TWRP recovery
Possible reason explained here
http://forum.xda-developers.com/showthread.php?p=56955843
Enjoy
Thanks for the hint.
Not sure if I get this. The problem was also there with the genuine Samsung ROM (lolipop)while the thread talks aout losing modem function after flashing custom ROM.
About previous I am not sure as I bought it used with 4.2.2 on it.
I updated to 4.4 and then 5 OTA, all genuine.
Only because the mobile kept on losing network I switched to custom ROM, but the problem persists.
At the moment I use the Pac-Man ROM 5.1.1 where it seems to be more stable.
Strange!
@augek
The linked thread isn't only about custom roms - you can end up with partly flashed baseband on genuine if you don't power off before download mode and flash using Odin.
Was the replacement job of SIM reader done by a qualified person?
Following your Suggestion i flashed the genuine lollipop with odin. Yes i switched of Prior to flashing.
And Yes the Person Who did the card reader Job is qualified.
Still the Problem persists.
So to me the question is if the Firmware (driver) is the Problem of my sim card. The sim i tried on my s4mini and doesn't cause Problems so far as far as i noticed.
P****es me of somehow.

Downgraded ยป Network Issues follow

I Recently began to have issues with my Z1 (Google frameworks and gapps were wrecked(dont ask how)) anyways long story short it ended up bricking itself for a moment, i eventually got it working through flashtool and flashed an old firmware as a result [.108] anyways since the new firmware had taking my phone, ive been getting issues with wifi and coverage has gone to hell. anyone got any ideas, it doesnt seem to be firmware related as i've tried a few at the time of writing...possibly something to do with 3g-4g stuff?, (Apologies for bad formating and gramatical errors currently writing this from a ps4 lmao)
Go to Settings and About phone and see the "Baseband" if it says "Unknown" then flash this and are you sure you are flashing the right FTF? look for the right firmware.
