I purchased the phone on eBay the other day however I cannot make/receive calls as there is no network signal nor WiFi. I found out that the IMEI and Baseband are missing and UNKNOWN. I made some research and apparently I need an EFS backup. I have no backups whatsoever as bought the phone from second hand just a while ago. I reflashed it using the flashtool but it didn't resolve my issue. Is there ANY way at all to fix Sony Xperia Z1 IMEI and Baseband? ANY at all other than going to the Sony Repair Service and ... replacing the motherboard which would cost same as the new phone. I would really appreciate any advice, help and some useful links!
Many thanks

Are you on the newest firmware with Android 4.3? Imei can be lost when you someone downgrades from 4.3 to 4.2.2. It should come back once you get back on the new firmware.
Try a few 4.3 FTF's and see if it solves the problem.

Try flashing one of the. 290 firmwares. 257 is the old 4.2.2 firmware. Have you tried to do a repair via PC Companion or Sony Update Service? Google it, download the software and try the repair.

I installed the Polish version, C6903 14.2.A.0.290 Generic PL 1276-4318_R1B MIRROR but had the same issue. Then I tried the repairs via PC Companion and Sony Update Service, and unfortunately nothing changed. I reflashed it again with UK version, C6903 14.2.A.0.290 Generic UK 1276-0875 MIRROR and nothing happened. The phone works normally but still it can't read the SIM card etc. As you can see on the screendumps attached there is no effect after installing any firmware or repairing it whatsoever. Is there anything else I could try?

Usually flashing the same firmware that you were on in the begining should fix the problem. All I can advise you is to try a few firmwares (same version and same localization) that you have had in the beginning with same android and build version. Try it until it comes back. It has to come back eventually.
The firmware is usually lost when you downgrade from 4.2 to 4.3. Once you upgrade to 4.3 it should return to the normal state. Are you sure that you are flashing firmware builds for your model number?
C6903 on C6903 etc.

Thank you for the quick reply. Znam Polski. : )
IMEI - "Unknown"
I do not know what Rom was before the upgrade to 4.3
On the box it says. Si 1276-2646 DE.
This Rom 4.3 which I flash "C6903_14.2.A.1.136_1276-4314 R1B Central Europe.ftf"
Probably the then everything disappeared.
Then I flash ".257> .290> .534"
Nothing has changed, I used an update by SUS.
SUS Flash Rom ".136" appeared restarts.
I went back to ".290"
I typed in Google Si 1276-2646 DE, I found Rom "C6903_14.1.G.1.518_GenericDE.ftf" thinking it was the "first". Unfortunately appeared bootloop. I had to go back to the ".290"
do you have the C6902 or the C6903?
I have a friend who had same case like yours, he contacted me on my gmail account, and i told him to check with variant he has... he was flashing C6903 but his phone was the C6902. however, this didn't solve his problem, so I told him u need to find a C6902 firmware ROM that came flashed in phone first time out of the box. eventually, he flashed his Z1 a C6902firmware which matches his phone network fuctions, and BAM.. IMEI and BASEBAND back to life with network and also WIFI.
just check your phone model and make a try, it worth it...
here is the thread bro:

Good luck

not all the cases succeed, depend if its a H/W problem, then it's hardbricked phone!
but maybe the latest update would fix this issue, not sure thou, because It was even worse from 4.2.1 to 4.2.2 or 4.3.

Try NUTs Downgrading to a 4.2 ROM.
It might be too late but try it.
I have the same problem but I try to flash PACman ROM 4.3.
I tried to flash baseband from stock Sony ROMs .136 and .290 but my IMEI is still 00000000 and I can't connect to network :/

H/W problem or Hardbricked depend on the phone's issue in which it was hardbricked. in some cases it can still make the phone turn on if it's related radio functionality , cuz It could be the modem or Chip. like imei and baseband problem.

An update of Sony Xperia Z1 to Android KitKat 4.4.2 14.3.A.0.681
Thanks for all the help so far!!! Recently I have reflashed my device to 14.3.A.0.681 Journalist&Commercial latest Android version and suddenly the IMEI and Baseband show up this time, and Wi-Fi works!. However I still got no network service (tried 3mobile and T-mobile; the phone does not ask for any unlock code). It freezes when turning the camera on :/ How to fix this? Is it still the software problem or something else?

Here is a tutorial I found in a quick Google search:

Hi,
1. Start the phone WITHOUT SIM card
2. Open the phone application and enter the following code: *#197328640#

"lightbox_next": "Next",
"lightbox_previous": "Previous",

}
3. Then go in the following menus:
Main Menu [1] UMTS
[1] Debug Screen
[8] Phone Control
[6] Network Lock
Options [3] Personal SHA256 OFF
On this screen, do nothing. JUST WAIT ABOUT 30 SECONDS.
Then go back by pressing the Menu button (touch left of Home button) then select Back
you are in [6] Network Lock
then select [4] NW NV Lock Data INITIALLIZ
On this screen, do nothing. JUST WAIT ABOUT 1 MINUTE.
Then restart the phone.
4. Now your Galaxy i9305 LTE S3 must be unlocked. There is no confirmation message. The way to check is to insert a SIM card from another operator.

This will not work on 4.1.2. You have to downgrade to 4.1.1, do the above, then use OTA to go back up to 4.1.2.

Hi,
I want to unlock my Galaxy S3 i9305 LTE bought from TMobile UK, and unfortunately Kies has already upgraded my phone to 4.1.2, details below:
Model Number - GT- i9305
Android Version-4.1.2
Baseband version - i9305BVBLL2
Build Number - JZ054.I9305XXBLL5
Now when I go to Sammobile to donwload 4.1.1, you can see in the picture the codes don't match up where Sammobile has EVRBLL1 or EVRBLL2 under CSC and I have BVBLL2 or XXBLL5.
There is no option for TMobile in Sammobile.
Can anyone please help me or guide me what should I do ??
Thanks in advance.

Dude i was in the same boat as you. I wanted to roll back to 4.1.1. to unlock my phone so I downloaded the EE version cos there are no seperate roms available for Orange or T-mob they all operate under the same umbrella (EE). I used this guide to help me its pretty straight forward:
http://forum.vodafone.co.uk/t5/Samsung-Galaxy-S3/How-to-Flash-Rollback-Galaxy-S3/td-p/1273246 (I know its for original s3 but dont worry the guide works for LTE version aswell)
Instead of downloading firmware from sammobile I used this thread to download the original 4.1.1 stock rom:
http://forum.xda-developers.com/showthread.php?t=1942150
look for:
Product Code: GT-I9305TADEVR (4.1.1) (EE UK)
PDA: XXALI5
PHONE: BVALI5
CSC: EVRALI5
Released: 17/09/2012
Once you done that. Unlock your phone and finally use software updater via about device to upgrade back to 4.1.2. Baseband and built number will be the same as your present one. Job done! its easy and painless!

6602 does not support LTE.
However 6603 and 6602 can use the same firmware.
I do not think flashing this firmware to a 6602 will make it magically support LTE.

Hi guys, please I need some help with my xperia z, it presently does not get any network regardless of changing sim. Dis occurred few days after upgrading to newest firmware .67. It worked fine after some days but signal started gettin poorer.realised dat after givin the phone a little bump it comes back to full signal.eventually it stopped getting network altogether, except in rare cases when I feel I'm close to a tower , it searches but cannot register on the network sayin to ensure that a network signal is in range 99asu.I also cannot switch to manual select of network. Please anybody with a solution. Want to know if its a hardware or software problem. I don't have a sony service centre here that can help me.thanks

What model do you have??
You upgraded by PC Companion or by flashtool?? Maybe the baseband is incorrect and the phone don't have signal, maybe your carrier use two band and not both are in all coverage.

Initially upgraded to .434 using flashtool, then .67 by OTA. By baseband do u mean 2g and 3g? Cos I don't get any form of signal at all.
Hi there, I have had the same problem: after updating the XZ to 4.2.2 (2.67 over OTA) the signal dropped instantly. Therefore I had to send it back Sony Care. They fixed it. The update has overwritten a different smallband/baseband-version above the other one, just as I suspected. I bet you can flash it yourself (your an XDA user..) instead of waiting 2 weeks or more. If you don't know how it works and you've absolutely no experience with flashing, just send it back to Sony care.
I think the easiest way is to flash a different (older) baseband-version on your XZ, reboot/factory reset and see if it works. The second method is to try downgrading the software to .244 INCLUDING the baseband-version, then update it by flashing the XZ to 2.67 while EXCLUDING the baseband-version. The third option is to re-flash (with flashtool) the 2.67 update but a different version (GLOBAL).
My phone details:
Modelnumber: C6603
Android-version: 4.2.2
Smallbandversion: 9x15A-ACEFWMAZQ-30110068-44
Kernelversion: 3.4.0g43a9ba9
Buildnumber: 10.3.1.A.2.67
Altough your smallband/baseband may differ from mine. Therefore, please find your own software-version. I'm using:
GLOBAL-LTE_10.3.1.A.2.67 (Netherlands)
Goodluck! Please let us know about your issue:fingers-crossed:.

But what Xperia Z model do you have?? C6603, C6602, C6606??
I have a similar situation in the case of C6603, in my carrier sometimes I have 2G signal but never 3G and other times no signal. In the case of OTA or PC Companion updates, sometimes upgrade to diferent model or carrier, I have a friend that upgrade his Xperia Arc by PC Companion but with the uncarrier firmware. Maybe this is your case, the OTA firmware don't well upgrade your base band.
In this case I suppose that you can flash only the baseband by Flashtool, but be carreful that the firmware was made for your Xperia Z (C6603, C6602, C6606).

Look this: C6602 10.3.1.A.2.67 STOCK
If you have doubts and I can help you tell me.
To find your version, just dial *#*#7378423#*#* => service info => software info => File system version: ......; download it from Xda and (re-)flash it. I've read about this; it happens a lot with XZ's with the GLOBAL firmware. You've probably the same version. Good luck and please let us know

Try to flash full firmware, because you don't have signal at all, maybe could be hardware issue. Cultural question, You try your sim card in another phone, don't you?
Okay I eventually found out what the problem was.it's a hardware problem, connection of the antenna near the vibrator, bottom right when lookin at back of phone was loose.thanks to all who posted suggestions.eventually opened it myself.

The only way I know Is to get the right ftf file for your handset and flash it back to 4.4.4, if you can't find the right firmware for your phone, then you may have to create your own using xperifirm and flash tool. either way you will keep iemi number and be able to flash it on a locked bootloader.
