I have searched countless of Forums and gone through Google alot and i still havnt found a solution yet, but coming from Stock Rom C6903_14.2.A.0.290 with Unlocked Bootloader and flashing PAC Man Rom in CWM succesful, but as soon as i get into the Rom, theres no Signal and i also checked my IMEI and it just says 0000000000...?? Is there anyway to restore the IMEI number to get the signal back somehow, or do i restore a Baseband or TA from another Stock Rom to get the signal/IMEI back..???

My Xperia Z1 encountered the same problem after flashing C6903 14.1.G.1.534 Generic UK 1276-0875_R9A. The IMEI was changed to 00000000000000.
Here is the solution: Flashing C6903 14.2.A.0.290 Generic AU 1277-0078_R2B via Flashtool will restore IMEI (I got back IMEI)

If you use flashtool to flash 4.3 ftf you will get problems like not having signal after flashing previous version (4.2) and the solution that worked for me is to reinstall software using SUS. After that I was able to get signal when flashing 4.2

Hi all,
Same problem here : upgrade to .290 and install the PAC ROM, the install is ok but no IMEI (so no connectivity). Is anyone know how to solve without losing the rom.
If I flash the original/stock ftf, it works again, but it's not the PAC ROM, so 1 win for 1 loss.
Thanks
Android 4.3 obviously changes something in the phone so that if you jump to another version it won't get signal or IMEI.
Anyway, the solution is simple.
Flash 290 and then 257. You'll get the signal and IMEI. If you want, you can go to 534 from 257 and then flash any ROM you want.
P.S: you don't have to flash 534, but you can do it if you want.
@Just2Cause
I unlock my BL so if I downgrade to 257, the camera will work or it will have the same "bug" as the 4.2 FW. after flashing to 257, do I need to stay on a 4.2 FW to keep the IMEI or can I flash the PAC ROM (which use a 4.3 FW) ?
Also, when I did the upgrade to .290 I use the sony companion app and it gave me no probleme (IMEI, call, sms was ok) it's specifically the PAC ROM that reset the IMEI. So I wonder what differs at low-level between the stock .290 and the PAC ROM, that can affect the IMEI
Tks
Download any .ftf (GENERIC is recommended) flash it using flashtool, and download the .ftf kernel for that specific ROM that you have flashed and flash it also using flashtool. i had the same problem downgrading from .290 to .534 i forgot to flash the kernel for .534 so i was stuck with IMEI 000000000.
Cheers

It's not the PAC ROM that resets your IMEI, I also got same problem when I downgraded from 290 to 534.
I'm afraid that you will lose camera (not sure, just maybe) after downgrading you will be able to install PAC ROM without any problem.
There must be something in Sony 4.3 firmware that needs to be ported to other ROMS so the camera gets fixed.
I got it working!
IDK if you guys have figured it out yourselves but here is what I did...
After unlocking my bootloader on .290 I flashed the latest nightly build of PAC-man. Same as you guys My IMEI number was 000000000.
So what I did was flash [NUT]'s .534 ftf for downgrading to 4.2.2 (found here: http://nut.xperia-files.com/files/C6903_14.1.G.1.534_[NUT].ftf.torrent) which brought back my IMEI number!
From there I rooted my phone again, flashed the boot.img for recovery, flashed the latest build of PAC-man and tada! Everything is working.
Flash the latest firmware(.757), flash doomlord's advanced stock kernel(not the main one), flash the rom of your choice from there that includes kernel (like PAC) and now it REALLY is working.

On nut.xperia-files.com there is no 534 rom for c6902 its only have c6903
Is it fine if i flash C6903_14.1.G.1.534_nut to my c6902...
I also have the problem with network. Not with this particular build, but with all AOSP roms. "Formatting boot, system, cache, data, and everything you see" will help my phone not recognizing (or invalid) sim? Are there network drivers I can flash from zip? Sorry for asking this, but I don't want to flash again and spend 3+hours figuring stuff out and then finding out later I can't call.. I need network to work as calling is what makes my device a phone, not a tablet. Help would really be appreciated.
I've used...
-LiquidsmoothBETA3 kitkat
-Paranoid Android BETA7
-Slimkat
-AOKP kitkat
My current rom in use: 14.3.A.0.757 (NUT). I start the process by flashing 14.1.G.1.534 (NUT) then adding root (Bin4ry) and dual recovery (NUT) before going to AOSP roms.
Model number - C6903
Sim card - Tmobile pre-pay.
Quote from a Thread in XDA:
01. if u are coming from stock to AOSP then Downgrade to 4.2 .534 FW having Root and a Recovery ( but i think if u downgraded to 4.3 .290 FW then also it will do the trick )
02. Follow the instruction in OP with the recommended instructions - "After 5th point in Recovery go to mounts and storage and then Format boot, format system, format catche, format data, format everything u see.. Except SDcard1 (ofc).. And then move to 6th point."
If u flash .757 before coming to PA or any other AOSP ROM's then u might have trouble
As u have already done Step 01 then do a Clean reflash again with step 02.. hopefully it will solve ur problems

Flashing from .757 gave me a bootloop. There are no more links to .290. Hmm...
Hello,
I have been trying all day to install a custom rom on my Xperia Z for T-Mobile. I have succeeded in rooting it and installing the recovery, but it looks like the bootloader needs to be unlocked. I have followed this guide and have rooted and installed the recovery but when I install a custom rom, such as paranoid android lollipop, it gives me an error and I cannot reboot into a rom so I have to run the Sony PC Companion tool and repair the device. I now have a completely stock Xperia Z and wanted to know the best way to install a custom recovery and flash a rom. I have tried unlocking the bootloader but it says bootloader unlockable no when I dial service, even after installing root and recovery. I have tried anyways and it says operation not permitted when I try to cmd the unlock code into fastboot. I was hoping someone could help me and guide me on how to fix these issues and finally install a custom rom.
Thanks
T-mobile Z bootloader cannot be unlocked, therefore you cannot flash custom kernel, therefore you cannot flash a ROM that uses anything other than stock kernel. Look for the "LB" tag in the ROM title, these are for phones with (L)ocked(B)ootloaders, and should be STOCK based ROM's.
Just make sure you follow proper procedures when upgrading to different versions of Android.
Got my Z1 the other day and flashed some firmware on it(cant remember which one) then rooted it, unlocked bootloader and flashed dual recovery to it and then flashed my rom. Rom worked fine etc but sim card was not detected because IMEI is 0.
I read up about this and followed a guide which involved flashing .290, then .257 and then after that to root the z1 and then flash .534 and then install recovery and then install my rom. This was supposed to 'fix' the imei problem but i've just finished flashing DU 5.1.1 and my IMEI is STILL missing and now I have no idea what to do next.
I want to run a custom rom but still be able to have simcard etc.
Any help would be greatly appreciated.
Thanks

If you have C6902, then you have to flash the corresponding fix, which is in Z1 threads. Search for it. If you have C6903, then either reflash your original ftf firmware with flashtool or flash C6903 baseband only from the same ftf (also with flashtool). If you can't find original firmware, just flash baseband for your type (C69XX). And next time, read about the firmware/rom you are flashing (and write it down) or you may brick your phone...
Greetings,
I have unlocked my Moto X 2014 victara, and installed TWRP & a costume ROM, now I am able to boot the device, but it shows no service, SIM card was detected, but no service, I did the trouble shooting as the following:
1- I checked IMEI number, it is present
2- I dialed *#*#4636#*#*: tried to enable RADIO but I couldn't
3- Flashed modem and fsg.mdm from stock ROM by fastboot, but still not working
Now even if I want to go back to stock ROM by fastboot commands it pauses at startup, but when I flash a costume ROM it goes alright, except the SIM card no service issue
Any help please?
UPDATE: I fixed it.
I downloaded Kitkat and Lollipop from this website:
http://www.graffixnyc.com/motox.php
Then I flashed 4.4.4 using fastboot followed by 5.0 using fastboot too
There are a lot of article in the community explains how to flash stock ROMs
My problem was I was using the Brazilian firmware while I have the US version. Now everything is going great.
Hi, I had a problem where I flashed a custom ROM and lost my IMEI / baseband - none of the SIMs worked.
I fixed it by flashing the Devbase ROM from this forum. The only issue is, whenever I flash any other ROM, I lose my IMEI / Baseband, including the stock from SamMobile.
As the battery is so awful on One UI V1 I'd love to be able to go back to stock so I can get the pending One UI update.
Any ideas?
Thanks
Jamie

because uve not updated your baseband(modem) and or bootloader are too old or too new compared to the rom you are on. but usualy its too old.
often people flash roms left and right and never ever think about updating BL and CP. they eventually will need to get those updated as well, not just the rom. its the users responsibility to manually flash the aforementioned files with Odin.
so all in all flash november 2019 firmware.( bl.md5 and cp.md5) you wint loose data by flashing those. nor do you need to reroot/twrp.

when you flash roms, have you made a habit to wipe before?
try to go to wipe menu and do factory wipe then flash a rom.
