Did you try to dial *#06# to check ur IMEI? Try to reflash .ftf file via Flashtool (find the one for ur region).

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?

Lol, yes I tried another sim card and it doesn't work, I also tried my sim card in other phones and works as a charm!
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

Thanks!

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)?

That's not needed and the OP says he does have IMEI so that's not the problem anyway

I flashed stock ftf, I'm not flashing a custom ROM.
Do you mean to flash .518, then 5.34 then .257 then .290 and so on to .757?
Thank!
Yes, I do have IMEI but I don't have signal, it's weird!
I had this problem with my old galaxy note 2
The radio chip most likely broken.
Contact sony for warranty if any left!

When I insert my sim it shows my a message that says "SIM card could not be read".
Could the problem be the sim card reader ??
Thanks!

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
So I recently Rooted my LT30p and everything seemed fine until I tried to make a call today, no networking signal wherever I go and the baseband version just states - Unknown -
Any fixes out there?
I dont mind wiping my device and setting everything back to unrooted and so on.
This is my first time rooting a phone so I have generally no idea whats gone wrong :/
I used Towelroot to root my LT30p
If you need any other information, let me know please.
Thanks

Imei null , baseband unknown
My mobile was not switching on 3 weeks ago (this happened when my imei was null and baseband was unknown) , so i connected it to my pc and did something and my IMEI came back , baseband too came back everything was working fine.
But yesterday my mobile froze and it was completely not responding , it was not even switching off, so i pressed power and volume up button it switched off, but when i switched it on again, the imei & baseband was gone .
What to do now?

is your device switching to flashmode ?
if it goes in flash mode then follow this steps
download pc companion and install it,then open it and click on start in support zone section, then select repair my phone
Then select your device and download the original firmware, then after downloading the original files ....minimize pc companion and download flashtool from here dl-developer.sonymobile.com/tools/Flash_tool_for_Xperia_7.zip now install flashtool and drivers (drivers will be in flashtool folder in c drive) now open my computer and navigate to here C:\ProgramData\Sony Mobile\Update Engine\localstorage\13740270
now make a ftf file of this (how to make ftf file https://talk.sonymobile.com/t5/Xperia-mini-pro/How-to-get-ftf-ROM-from-PC-companion-update/td-p/178996)
now flash that ftf in flashmode
