What options are you choosing to flash in flashtool. Select wipe all and don't exclude anything in flashtool. Try that.

Flashed in that manner only. Wiping all and not excluding anything.
I have a doubt. There is nothing related to 'Baseband' in contents list or in exclude?
I read somewhere that i need to flash baseband from ftf in order to fix. Is it true?

Bro all you need is a sony flashtool, sony pc companion, your z1, and some patience.
first of all make a ftf of original firmware for you device this might help second step flash the ftf which you made using flashtool (remember this ftf is the orignal copy of stock firmware).
after flash process finished just simply turn on your device and this might get back your modem's and signal and yes your imei number as how it should be.

got it :good:
you need Flashtool installed and then extract the FTF via 7zip
select sin editor from tools menu of flashtool and browse the file kernel.sin from where you extracted the FTF file
then click extract data and you will see a kernel.elf file has been created in the same dir as where you extracted the FTF file
let me know how it went
i just did that and it went fine

there is no need to do that.
If you have a stock kernel.elf you can flash it using fastboot (Or flashtool in fastboot mode) on both locked and unlocked bootloaders

[Q]HOW TO convert zip to ftf file..try almost all xda methods cant success..

i tried almost all metods to convert zip to ftf but cant got success...kindly help guyz so I can ROOT MY Z1....PLZZ
You don't have to "Convert" but just to rename the extensions of the file to flash it. For example if it is C6903_Unbranded.zip you have change it to C6903_Unbranded.ftf. If you do not see the extensions on your PC go to Control Panel > Appearance and Personalizations > Folder Options > View, then uncheck "Hide extensions for known file types", now you can rename it, flash it and click thanx.
done what you say

I don't know if this make difference but it should be in C:\Program Files\Flashtool\firmwares. Then if you can see yet the FTF that mean is something wrong with flashtool or the file which you downloaded. When I downloaded the file from NUT link I don't get .zip file but a normal .ftf file so I don't know yours where it come from but one guy had the same problem like yours and he just renamed the file and everything was gone fine. Try to download the file from different source. On this Video Tutorial by Shem, in descriptions there are links to download the .534 ftf by NUT, redownload again and let me know.

What the hell are you doing? Who told you to flash .514? It do not exist. Download from HERE the C6902 14.1.G.2.257 Commercial/Journalist 1277-1348_R1A and flash it on your phone. Turn on your phone and check if everything is ok, switch it off and hold volume down and connect in flashmode, then Downgrade again to C6902 14.1.G.1.534 Generic TW, Root this Firmware with Bin4ry Application and when you are rooted then follow the instruction to update to .290 from HERE, then update again to .136 from HERE. Read carefully all the instructions. This method is for Locked Bootloader and if you do all correctly you will have .136 fully rooted.
thanx for help

Xperia z3 D6653
Ok so I was trying to flash my z3 back to original Sony software because I was getting an error message in PC companion saying my phone cannot be updated because it contains modified software and I was flashing it using sony mobile flasher by androxyde and I forgot to enable USB debugging and unknown sources and now it's in a boot loop telling me "software update failed. Please plug your phone back in and try again"
Any ideas?
I was told to try using a different computer?
Hi all, if anyone is having trouble flashing with flash tool because usb debugging isn't enabled error then do this procedure.......
1. Dowload latest flash tool 0.9.18.8 and also version 0.6.6
2. Try use the latest version first to Flash the tft rom. NOTE: remember the file it has error flashing e.g on my experia sp file system.sin was not able to Flash bcoz usb debugging error (enable usb debugging and unknown sources) ALL THE REST of the files flashed ok!
3.try flash again the rom but this time tick system.sin (or error file) in flashtool to exclude it from flashing. Make sure all other files are included. Also tick all wipe caches options and flash rom without system.sin (or error file).
4. Flash procedure will work. Now disconnect phone and leave it off without restarting it.
5. Uninstall flashtool latest version 0.9.18.8 and install flashtool 0.6.6 old version and open it to Flash the same rom BUT THIS TIME only select the system.sin file (or error file) to be flashed and rest excluded. Make sure all wipe options in flashtool are enabled and Flash! THE FLASH WILL WORK WITHOUT USB DEBUGGING ERROR and your phone will be fixed!
Press thanks if it helped!

U can flash stock rom... Then root it,install recovery and de odex it... Why u need pre rooted rom? if there is way to root it easily...
I know that but its difficult to get drivers everytime fot flashtool and its difficult to root latest firmware
Flashtool is for flashing unmodified stock firmware packages only in flashmode. You can't make modified FTF files.
