[Q] Unable to connect to mobile network after failed flash. - Xperia Z1 Q&A, Help & Troubleshooting

So trying to put CyanogenMod onto my phone, I haven't been able to use it for a while because all I had was a black screen. Late last year, I manage to get it up and running again. Everything worked fine until an hour after flashing the stock ROM onto my phone, the connection to the Mobile network disappears. I flash the phone again and the mobile network connection is only temporary. Anywhere between 20 mins to 3 hours. The phone can't scan for any mobile networks at all. Everything else seems to work fine but what's the point of a phone that doesn't make calls?
Any ideas or additional information you guys need to get this cellular-less cellphone working again?

Hey,
My Z1 has also been having a mobile connection issue for a while now.
Scans for networks, finds some of them, but cannot connect to any.
Flashed every stock F/W i could find, tried several working SIM cards, did a TA restore.
A few days ago I replaced the chip with the speaker, radio and antenas on it ( 13 $ from china ).
nothing.
Any ideas are welcome.
Thanks guys

You both try first to restore TA and relock your phone. then reflash stock .157 FTF. Or maybe, flash a custom kernel that match to the current FW you are running. if it is based on .157, look for custom kernel that runs at .157

yes, dear tried all the flashing, TA and custom kernel crap. got fed up with it already
I never went outside stock firmware, tho. I saw that OP was trying CM before it happened.
and my phone used to be carrier locked, but I unlocked it with a code about 2 years ago. Could that be acting up? I am not familiar with the low-level stuff

Yep... I did all that flashing too. All started with that failed CM flash.

Sounds like a failed modem flash or baseband

I have just noticed when I dial *#*#6463#*#* to get the phone menu up and selected the 3 vertical dots, under select band, I only have the USA bands. Where did all the others go? How do I get all the others back?

Normally it would, if you choose a Pure Stock (with no additional stuffs). i experience it also one time. I was on LB then installed the ParanoidAndroid (CM Based ROM) then i lose my network. i just relock my BL, flash the custom kernel.

Hey man, sorry i forgot to read my own comment about flashing the FTF. Can you try to insert another SIM in your phone? or inserting your SIM to another phone? (Maybe your network provider has the problem?) Have you tried also using the PC Companion? or the Flashtool for Xperia? though you need to unlock your phone if your gonna use the Flashtool for Xperia, but you can relock it later.
Let's try to do anything we can do before you let go some of your cash.

Good ideas, bro Sadly i tried all of them ( except Flashtool for Xperia, since my bootloader is not unlockable ). Several SIM cards, various operators in 2 countries. As I mentioned in my first post, I even went as far as ordering a new radio unit ( a chip that houses the speaker and radio + two antenas ) and swapping it in. Did all possible factory resets. retored TA ( even tho my IMEI and Baseband show up ok ).
2 years ago when I had to carrier unlock my phone, I did it with a code and it worked alright for a very long time. This is the only thing I can think of that might be wrong with it, but I tried a SIM card from the operator it was originally locked for and its the same.
It detects the SIM card, it scans for networks normally, but when I try to connect manually to a network it says "unable to connect to network, check if sim card is in or you are allowed bla bla" . Automatic network selection gives no result

[Q] Can anybody make a "csc" file for the kitkat?

I had my SM-N900A running fine after i got the update from samsung and lost my kingo root access and it somehow messed up my phone. after playing with the phone a whole lot i can flash kitkat on it. but no matter what i flash or whatever i can not get any type of network. it just weird. i know the csc file supposed to be the network and region operator file. but somehow, someway i can not get any other file for csc except for the MI9. which always failed with that bootloader update that came now. phone is working fine on kitkat it's just that i have no network access. not even the 'ATT' logo won't show up. i went to mobile network under setting and click on it. no success. any help would be appreciated

I don't really know but I don't think my problem is baseband problem cause I'm running "MLG" rom but when i flash modem/baseband version other than this "mlg" it shows unknown baseband version. Only "MLG" modem is recognized and somehow there's all sort of stuff wrong with this roms/or with my phone. I got that circle sign thingy with the slash in the middle showing I don't have any network at all. Idk... I'm running into all sort of weird stuff with this phone.any full wipe/cleaning with brand new roms or whatever would really help. I just want the phone to make phone calls. Phone is kinda working fine when I flash other modem in it (NC2) (can't make phone call though) but it doesn't recognize the baseband version. Here is another picture with the MLG baseband which it recognized but no network though.

I don't think a csc file is what you need...NC2 is official KitKat, your buildnumber ends with MLG, which means you are on the leaked build of KitKat. Both are 'KitKat', but they're are different firmwares...based on the problems you've described here I think your problems are coming from mixing pieces of MLG and NC2 together. It sounds like you may have some experience with odin from flashing modems, I think the easiest thing to do is to do a full flash to NC2 to clean your system up. This will get rid of the signal issues caused by different modems and you'll have the full NC2 firmware (bootloader, baseband, recovery, etc) for a solid foundation to flash custom roms on
Obligatory warning: once you flash official NC2 you are locked to it and you can NOT downgrade to anything with a lower build number - anything with MLG, MJ5, MI9 is out unless you really really really know what you're doing so definitely read up on that if you're not sure and decide if it's something you want to do.
If it is, it's easy as pie all of the NC2 files you need to flash via Odin are in this thread: http://forum.xda-developers.com/note-3-att/general/n900aucucnc2-odin-files-t2838117
If not, I'd still recommend reflashing full firmware...just MLG though

Not sure what you mean by ime, but a clean flash to NC2 fixex pretty much everything!

IMEI but No Signal, please help!

Hello
I'm new here and I don't know what can I do to fix my phone, please help!
I have a Z1 C6903 from HK and suddenly during a phone call my phone lost signal and now it can't connect to my carrier network.
I tried a factory reset, upgrading with SUS and flashing original HK ftf but still have the issue.
I also tried flashing different ftf files (.290 , .257 , .534(NUT) , .531 , .681 and .757), sometimes I lost my IMEI but I figured out how to recover it, however, I recovered my IMEI but I still have no signal at all.
Could it be physical damage on my phone?
I hope I can fix it with software.
Any ideas?
I don't know what else can I do
Thank you!
you tried many ways, but did you try another sim card, lol?

I noticed that this happened to other people and they fix it with SUS or flashing other ftf, I guess I'm not that lucky
Thanks!
After downgrade via flashtool did you try OTA update? Sometimes it's lose imei when flash older firmware, but after OTA update imei will restore. Hope it can help

Did You try to manually flash each ROM following the release versions, from the oldest to the newest without skipping any build number (else You won't get signal and IMEI)?

Do you mean to flash .518, then 5.34 then .257 then .290 and so on to .757?

Hi, I don't think is the radio chip, because I can see my carrier signal using the app Network Signal Info.
And it seems thta is not SIM locked, no X on the left. I don't know what can be the issue
Sorry to dig up this, but have you figured that out?
Were you to get signal again????
If so, what did you do?
hey did you figure it out? i am having the same problem! though it occured after flashing a custom rom. i noticed lost imei but then i recoverd it. now i have tried almost every ftf and even SUS. imei appears but shows no sim card inserted

[Q] Lost network & relocked BL?

Hello,
I've a weird problem with my Xperia SP. Today i wanted to get back to rom based on stock rom to get miracast feature.
I downloaded newest existenz rom and williams kernel for stock based roms. Installation went fine system booted ok and everything worked fine. After some time phone turned off and didn't wanted to start. Only flashmode worked. I've decided to download stock .205 CE1 rom and flash it.
It booted up, sim card was recognized(had to write PIN). After that network was not found. Signal with red "X". I've tried to manually register to network but i could not.
Next thing is that after flashing stock rom fastboot mode stopped working. Service menu shows that Bootloader can not be unlocked even that it was unlocked before and flashtool(BLU option) shows that it is still unlocked. Flashtool also shows Bootloader: NOT_ROOTABLE.
I have actually no idea what have happend. Now i'm installing stock rom using Sony PC Companion but i think this wont help for network problem.
My main network is PLUS GSM(Poland network).
Could sim card die? It is old type card (almost 10 years) and i had to cut it manually to fit micro sim for the phone.

Use flashtool to flash stock firmware by ftf file. Here:

Use an older one and if that does not work, try one or two more. Hopefully, that will help. Best of luck!

Does it matter which country is it for? I can try some of them but i think that won't help. I've checked other sim card and it was recognized but didn't even ask me for pin. Weird Oo.
If nothing helps i will just flash stock firmware with SEUS and let sony service take care of it, hopefully. Phone still has guarantee.

Regions perhaps. But the thing that does not make sense it that that why did it work before and not now? It should work. Anyway, my SIM was mini too. I, too, had to cut it. It works. Or possibly contact your service provider maybe something is wrong with the SIM. They might have have locked it or something?

If none sim card works on phone then it is IMEI problem or phone itself somehow. I'm trying to flash other roms now. Hopefully it will help if not then sending to service.

I've reflashed stock rom using SEUS and sended phone to sony service. Hopefully they can help. Be careful with Williams Kernel for stock roms. This may be a common bug.
For anyone who had the same problem. Sony exchanged my whole phone with information that mainboard was broken. They said that phone could not be fixed.
Good luck

[Q] Xperia V update from android 4.1.2 to 4.3 / firmware 9.1.A.1.140 to 9.2.a.2.5

Good day, I have a problem with my android and firmware update. I have seen some blogs about xperiaV posting that they already have JB 4.3 update and the latest version of firmware 9.2.a.2.5.. I am wondering how they update it 'cause when i connect my phone to Pc and run the PC Companion, i check the update and it says my phone/tablet is up to date, but the android version of my phone was still 4.1.2 and the firmware version is 9.1.a.1.140.. I don't understand what is the problem of my phone or at my PC Companion Software. I tried also connecting my phone to internet and check for update and still it says my system is up to date. My main concern why i wanted to update my phone, it is because my phone is now dead signal as in no signal (by the way i'm form the Philippines using Smart Communication Network postpaid) I've already switching the network from GSM only and to other choices provided but still no signal. I tried switching my Airplane mode and it displays an airplane icon on the signal area (I think airplane mode is working well, never tried using is). I've read some blogs also that you need to root your phone and flash the firmware and so on to update the android version, but i think its just changing the room, not really updating the system. I don't want to do that 'cause my phone might turn into bootloap 'cause i don't have much knowledge on doing that. I've read also some blogs stating that there is a bug or network issue on version 4.1.2. So i am looking forward from anybody here in the forum who can help or teach me what to do to update my android and firmware version.
I am not sure of it useful to 'upgrade" the phone to solve a problem - this problem of yours. If I were you I'd use the repair my phone option in PC-Companion first, and then see what happens with the phone signal.
You can simly flash any ftf file for your phone with flashtool. Not the sony one. You don't need root access for it

Look at this: http://forum.xda-developers.com/showthread.php?t=2648320
Download 9.2.A.2.5 unbranded coming from Singapore or HongKong (since you're from Asia) and follow the instructions to flash.
Good luck

You can jump straight to 9.2.A.2.5
It's important that you wipe all your data... and Flashtool will do it for you automatically if you don't change anything just before flashing
Mr. Istux got an OT question here. I have concern also on my network set up. I want to unlock my network so that i can use other sim card. My phone is Lock to Smart Communication Postpaid. So i wanted it to be open-line. Hope you can give some advise to solve my concern..

I actually don't know how sim-unlocking works.
Have you ever asked to your network? Usually they give you a code after having paid a little fine.

Back to my thread.still my phone signal is not working. i just found out w while ago that if i am in the higher place like 2nd floor of the building, i got a 2g network and my phone signal is working. but if i'm already at the ground floor the signal is not working. is it ok if i am going to do open line on my so that it will receive any type of network or is it really the software problem of my phone causing the signal not working??
