Find any 434 firmware(but not UK unbranded :D) and flash it with flashtool than boot your phone,after that use sus(sony update service) sure it will find a new software.
[Xperia Z Q&A, Help & Troubleshooting] Kiko_1272:
I thought the SUS Version may make a difference like how Flashtool has many versions but Thank you very much.
[Xperia Z Q&A, Help & Troubleshooting] Kiko_1272:
I flashed .307 Belgium as it was one I already had. Everything was working well however I had no Baseband and therefore no Signal and the phone wouldn't recognise my SIM card.

I then used SUS to update it and I am back to the same boot-loop as before.

Any ideas? Maybe I need to fix Baseband before updating but have no clue how to do that?
[Xperia Z Q&A, Help & Troubleshooting] shysparrow:
I'm desperate to fix Baseband but donno how.. even google is not helping lol.. I restored TA ALL OK but still same prob. can't even see my IMEI # using dial pad or Service menu.. Menu Hangs when tapped on customization..

I donno where what went wrong duh!
[Xperia Z Q&A, Help & Troubleshooting] Kiko_1272:
Hey bro I finally figured it out!! So after thinking about and wondering why baseband isn't working I realised it is because of missing IMEI.

Then I thought where would IMEI be stored; IN THE TA PARTITION!!

So what I did was:

1. Flash Belgium .307 with Flashtool.

2. Setup phone normally so that it is usable. Turn on USB Debugging and Unknown Sources.

3. Then get DoomLords Root Toolkit; Plug in phone normally while it is on and run the kit so that it Roots the phone.

4. After that restarts make sure you have Super SU and it is working.

5. Connect to Flashtool while the phone is on and it will automatically run through the phone and tell you all the details of the phone and Busybox and Root Access Allowed and stuff.

6. Once all is well and you know phone is Rooted and stuff; close Flashtool and open Backup TA.

7. Then simply Restore your TA partition.

8. Reboot and check your Baseband Version and IMEI number are present and correct.

9. All should be working now; Really hope it works out for you too!

I will be trying to update and see what that leads to.

If you need links to any of the above stuff let me know. Will be glad to help you out. :D
[Xperia Z Q&A, Help & Troubleshooting] shysparrow:
Great ..!! u managed to get the baseband and IMEI back?
[Xperia Z Q&A, Help & Troubleshooting] Kiko_1272:
I got everything back my friend. I also just updated to 4.2.2 with SUS and it works too!!

Are you going to try my steps?
[Xperia Z Q&A, Help & Troubleshooting] shysparrow:
Cool ... Gr8 :good:

Still downloading BE .307

By the way which ver of backupTA u hv used?
[Xperia Z Q&A, Help & Troubleshooting] Kiko_1272:
I have some old old version I guess but it is the only one that has never given me problems in backing up and restoring so long as my phone is rooted and busybox is installed. It has no version number or anything, its a really simple batch file.

I can pack it in a zip and sent it to you somehow if you need?
[Xperia Z Q&A, Help & Troubleshooting] shysparrow:
That would be kind of u, if u can upload it for me and post me the link. thanks a lot :highfive:

[Xperia Z Q&A, Help & Troubleshooting] AJBek:
Don't restore using some else's TA partition, it has to be the original one for you phone. Another user tried this and it totally bricked the phone.
[Xperia Z Q&A, Help & Troubleshooting] Kiko_1272:
I think he already knows; I sent just the tool anyway not my TA partition. :)

Thanks for the heads up though :)
[Xperia Z Q&A, Help & Troubleshooting] AJBek:
No bother mate, sorry to butt in, I thought for a moment you had sent him your TA partition rather than the tool.

IT TOOK ME 22 HRS TO THINK THAT I HAVE AN OLD PARTITION BACKUP.. YAY!

I FOUND IT AND THE DEVICE IS UP AND KICKING.. YEEEHUUU..

TA restore is not working!

I've created a backup of TA Partition before unlocking. Now when I check my IMEI all is get is a blank popup. I tried to restore TA partition but it didn't work.

There is one more thing...when I try to relock my Xperia Z using flashtool, I can see my IMEI number in flashtool window when it asks for the unlock code.

Please help!!!
[Xperia Z Q&A, Help & Troubleshooting] Kiko_1272:
Does backup ta say why it can't restore? Did you try the steps I have posted earlier?
[Xperia Z Q&A, Help & Troubleshooting] shekharsuman:
TA restore is not working!

I meant to say that the restoring of TA Partition is successful. It's just that even after successfully restoring I don't see my IMEI number on phone. Also baseband shows unknown.
[Xperia Z Q&A, Help & Troubleshooting] Kiko_1272:
I had the same sort of thing; even-though TA was flashing in 4.2.2 it didn't fix my phone so I had to downgrade and then restore TA and then upgrade to 4.2.2 again.

What firmware are you on now? and Did you try to follow all the steps I have posted in this thread earlier?

EDIT:

Here are the steps I was talking about. This is the only thing that fixed my phone.

1. Flash Belgium .307 with Flashtool.

2. Setup phone normally so that it is usable. Turn on USB Debugging and Unknown Sources.

3. Then get DoomLords Root Toolkit; Plug in phone normally while it is on and run the kit so that it Roots the phone.

4. After that restarts make sure you have Super SU and it is working.

6. Once all is well and you know phone is Rooted and stuff; close Flashtool and open Backup TA.

7. Then simply Restore your TA partition.

8. Reboot and check your Baseband Version and IMEI number are present and correct.

9. All should be working now; Really hope it works out for you too!
[Xperia Z Q&A, Help & Troubleshooting] shekharsuman:
Same Steps!

Yes. I have followed the same steps except that I've the .307 version of android from TAIWAN! Right now I'm on the same .307 TW version. For some reason when I flash the .423 version (downloaded from NUT's post) my phone keeps on restarting. And can you tell me one more thing -- is the IMEI information contained in TA Partition? Also what is that EFS folder?
[Xperia Z Q&A, Help & Troubleshooting] Kiko_1272:
Yea as far as I am aware the IMEI is in the TA Partition. It contains pretty much all the information that is unique to your phone. Hence if you flash someone else's TA Partition your phone Hard Bricks.

So the way I figure it; with our missing IMEI and Baseband and so on the phone is like Semi-Bricked.

Have you tried flashing only the Baseband of either firmware through Flashtool. After selecting the Firmware un-tick everything apart from the Baseband. (Although that didn't work for me last time I tried.)

Also I am guessing PC Companion or SUS doesn't recognise your phone since it keeps rebooting now?

Im not sure about an EFS Folder? Sorry. :S
[Xperia Z Q&A, Help & Troubleshooting] shekharsuman:
Yeah I've tried flashing only baseband. It didn't work for me too. Right now I've reflashed to .434 version and relocked the bootloader and I'm now updating my phone. Let's see if that works.

---------- Post added at 03:22 AM ---------- Previous post was at 03:14 AM ----------

Even after updating via Sony PC Companion, I get this error after phone boots everytime ----- "FACTORY STARTUP SERVICE - Please wait for POWER OFF button" I guess now I've to take my phone to Sony Service Center.
[Xperia Z Q&A, Help & Troubleshooting] Kiko_1272:
I was getting that too, what happens after?
[Xperia Z Q&A, Help & Troubleshooting] shekharsuman:
Nothing. It keeps restarting. I've to reflash to .307 version. I've tried 3 different ftf for .423 (4.2.2) version and they all give me same (POWER OFF) error. When I click on use phone, my phone keeps restarting. Although I get the same warning in .307 version, my phone works fine after I press use phone. This is happening only after I'm updating my phone to 4.2.2 android version.
[Xperia Z Q&A, Help & Troubleshooting] Kiko_1272:
I got the exact same thing. That's while while my phone was working in 307FW I Rooted it and then restored my TA Partition. Then after a restart my DRM Keys, Baseband and IMEI were all back.
[Xperia Z Q&A, Help & Troubleshooting] shysparrow:
Downgrade to (4.1.2) .307 (Indian FTF) root it using doom's toolkit. then try restoring ur ta partition. once the restore is successful u shud get OTA software update notification for 4.2.2

U'll hv blank IMEI, Service menu hangs when configuration is tapped, baseband is unknown, no connectivity, phone keeps rebooting these all what happened to me.

Edit................

As per ur location ur device is c6602 so BE .307 c6603 won't work for u as I've tried and failed. Try flashing c6602 ftf, Indian --- recommended..
[Xperia Z Q&A, Help & Troubleshooting] shekharsuman:
This maybe a NOOB question but I don't know how to downgrade. And I can't find any ftf for .307 indian version for C6602 device. Please help!
[Xperia Z Q&A, Help & Troubleshooting] gm007:
You can use any firmware, .253 is fine if you can find one and use flashtool.
[Xperia Z Q&A, Help & Troubleshooting] shysparrow:
1. Download this firmware [FIRMWARE]{C6602} Stock 10.1.A.1.434 INDIA unbranded Flash it via Flashtool (download latest version 9.11)

2. Root it using Bin4ary Toolkit (Connect it to flashtool with USB DEBUGGING ON/ UNKNOWN SOURCES)

3. Restore TA Partition (use toolkit v8.0)

4. If restore didn't worked, Flash ftf again Excluding Partition this time and reboot

5. This is the only way to get everything back

[Xperia Z Q&A, Help & Troubleshooting] shekharsuman:
yeah! I think there is no option left other than taking it to service center.
[Xperia Z Q&A, Help & Troubleshooting] Hubriss:
If your phone is under warranty then you should take it to the service center.Sadly for me,mine is 2nd hand without the papers & i'm not covered.The service center guys couldn't repair it & said they can only do a handset replacement & handed me my dead phone back. :(
[Xperia Z Q&A, Help & Troubleshooting] shekharsuman:
So now you have a phone with no network?
[Xperia Z Q&A, Help & Troubleshooting] Hubriss:
Yes.No network n no wifi & keeps restarting itself.
[Xperia Z Q&A, Help & Troubleshooting] shekharsuman:
Same thing was happening to me. I now use PAC Rom in which wifi works.
[Xperia Z Q&A, Help & Troubleshooting] Hubriss:
do u need an unlocked bootloader for PAC Rom?if so,how did u manage to unlock bootloader?My phone restarts every 2-3 minutes so I can't do much with it.
[Xperia Z Q&A, Help & Troubleshooting] shekharsuman:
I pressed volume up + power for 10 sec. There were 3 vibrations and then phone switched off. After that I used Flashtool to unlock my bootloader.
[Xperia Z Q&A, Help & Troubleshooting] Hubriss:
So basically,ur phone is working normally with PAC Rom except for no mobile network?Or does it reboot after every 2-3 minutes like mine does.

If no, then did that happen to u before u flashed PAC Rom?
[Xperia Z Q&A, Help & Troubleshooting] shekharsuman:
Same thing. I updated to version 4.2.2 and then my phone kept on restarting. Then I did the thing I said earlier.
[Xperia Z Q&A, Help & Troubleshooting] Hubriss:
i need to try ur method.i was starting to think that it might be a hardware related problem.
[Xperia Z Q&A, Help & Troubleshooting] shekharsuman:
Good luck. Keep me posted.
[Xperia Z Q&A, Help & Troubleshooting] Hubriss:
Sure.Downloading ROM as we speak :)
[Xperia Z Q&A, Help & Troubleshooting] Hubriss:
So last night I unlocked the bootloader & flashed PAC Rom.The wii-fi was working but no network.

But then my phone restarted again after 5-6 minutes.

Seems like my handset has multiple problems.It could be the battery and/or storage itself.I'm quite sure now that it is a hardware problem :(
[Xperia Z Q&A, Help & Troubleshooting] shekharsuman:
Try Cyanogen Mod too. Maybe that helps.
[Xperia Z Q&A, Help & Troubleshooting] DevShaft:
The reason your phone is rebooting can be because it can not find the SIM CARD. The Sony Xperia Z has this weird feature to prevent the phone to accidentally go on while on shipment. Does your SIM CARD work in another device?
[Xperia Z Q&A, Help & Troubleshooting] Hubriss:
Tested the SIM on another device and it was working.Can this be a mainboard related issue?Somehow I get the feeling that this is hardware related.I tried a few custom ROMs( Chameleon OS & PAC ROM.Tried CM but wouldn't boot) & the restarting problem persists.

Thank you for the reply.
[Xperia Z Q&A, Help & Troubleshooting] DevShaft:
This can be mainboard related yes, but we got to rule software out first. Do you have the LTE variant? So 6602 or 6603?
[Xperia Z Q&A, Help & Troubleshooting] Hubriss:
Its a 6603 LTE variant.
[Xperia Z Q&A, Help & Troubleshooting] DevShaft:
Can you try to flash this ftf and report back? https://docs.google.com/file/d/0Bz0UYx8a8nvPdXNralIyTXozcTQ/edit?usp=docslist_api

Sure.Will give it a try.(But my download speed is 2 mbps. So will take a while)

BTW, I have tried .434, .423, .244 but they all gave me the same problem.

(.423 & .244 wouldn't even allow me to access the Homescreen, App drawer or Settings Menu)

Edit:Flashed .253.Boots up fine.But the restart problem persists.

Also, if you missed my earlier posts, wi-fi isn't working & no mobile signal in any of the firmwares

Can't update via OTA(no wifi,no network)

PC companion detects my phone as C6602 & C6003 alternatively.But cannot check for updates.

I only get the option to repair inside Support Zone menu.
[Xperia Z Q&A, Help & Troubleshooting] DevShaft:
Weird that you can not check for updates, are you sure? Can you try a factory reset from within the settings of the phone and try update again?
[Xperia Z Q&A, Help & Troubleshooting] Hubriss:
Yea I know.Its weird.Maybe i forgot to lock my bootloader?now i can't remember.But will give it a go again.

Maybe it wud be good to mention a weird problem I had before all this happened.

When my phone was working fine & I was on .423 , i rooted using Doomlord's method & installed CWM Recovery.

All went well except I lost BE2.Weird because my bootloader was still locked.

Also,recently while trying out custom ROMs,i noticed that the Lockscreen wallpaper would sometimes disappear after a restart.

after unlocbootloader try flashing kernel, lightning kernel 4.4.4 for kitkat stock rom and flashing kitkat stock rom

if kernel miss with rom some trouble will occure. ( base on experience)

some times wifi error/not run make boot-loop, kernel not reading wifi ( base on experience)

So whenever I try to flash a ROM I get the following error:

E: unable to open zip file

Erorr flashing zip '/external_sd/Infamous_S4_v2.5.zip'

Updating partition details

I've had the problem since yesterday and have searched different threads with the same error but none seem to have a solution.

I've read that it could be the file and I have since redownloaded the same ROM several times and downloaded different ROMs and all give the same error.

I've ODINed back to stock and re-rooted and reflashed the TWRP recovery.

I've formatted my SD card which was a HUGE pain but it was one of the suggested ideas in the other threads.

And I STILL get the same error. I have no idea what else to do. I was fine on Infamous s4 2.4. I wiped and flashed 2.5 and i lost my status bar. Someone suggested to download and reflash and that's when the problem started.

Can you browse through the zips either through a file browser or on your computer? I kept getting that error with Faux kernel a while back. Thought I'd try to browse through the file on my computer and it would tell me it was an invalid file or something of that sort. I downloaded the same file maybe 8-10 times before I got one I could open; coincidentally enough, the one I could browse was the only one that would flash. What I'm saying, if you can't open the file, then it's a bad/corrupt file; regardless of whether you've downloaded it multiple times or not. If you CAN open it, then the problem would lie elsewhere.
