[Q] Sony Xperia Z bricked after custom 4.3 Rom

Hi All,
Hoping for some advise and hopefully a fix. Been scouring these forums for 4 hours and cannot find a problem the same as mine or one that seems like it would fix.
I've always stuck to nexus phones in the past so the xperia z is new to me. picked it up this weekend but i've already had enough of sony's custom skin so thought i'd get a custom rom.
I updated to the latest software version using the pc suite and then used the xperia z root tool (v16).
After this i downloaded root checker and verified i was rooted
i then downloaded cwm recovery and installed
i then downloaded the 4.3 google edition rom for the xperia z, put it on the sd card and went into recovery, selected it from sd card. said it all installed ok so selected reboot...
after this it didnt come back on and just vibrates once when you press the power button. tried the hard reset thing where it vibrates 3 times but after this it does nothing.
it isnt recognised when plugged in to pc and the only sign of life that i can see is the light flashing red when plugged in as if charging.
Any ideas? never had something not switch on at all before.

Is your bootloader even unlocked?
4.3 roms and all other roms with non stock kernels cannot be flashed on a locked device.

Easy. Just repair with SUS
or
Download flashtool, and download the corresponding firmware you need (should be .ftf format) (i.e. if your a UK generic user download UK generic ROM) and flash the firmware.

fixed
Thanks guys. Flashtool got me back up and running.
Now, just because I'm obviously a complete tool does anyone know off the top of their head if it is actually possible to put the Google edition 4.3 on here after all of that or should I quit while I'm ahead???

It is an advanced build of 4.3 based on CM 10.2.
Remember to fastboot flash boot.img of kernel before flashing it form recovery.
If all that seems too complicated then i advice you don't attempt it right away, read around the XDA forum and familiarise yourself before attempting to brick your phone :silly:

Dude does your bootloader unlocked? If not maybe it cause u a soft brick. Try to flash the original ftf for xperia z use the latest flash tool then reflash it. Hope it helps you. Btw welcome to the SONY world ;p

[Q] Back to 4.1

Hi experts,
before i try the new 4.3 rom i would like to know if it is possible to revert back to 4.1.2 later on.
Thanks
Attila

Of course. Flashtool + appropriate FTF file which you can find anywhere in this subforum and you can easily revert back to 4.1.2

Thx
Thank you,
then i give it a try.
Cheers.

Which needs unlocked bootloader, correct?
Which additional drivers need to be installed?
Is there a way to downgrade with locked bootloader? I am actually ok with the function of .199 but not with it's tons of bloat, and no way to install certain apps. No root is almost like having no sex ever.

Of course yes, flashtool is both for locked and unlocked bootloaders! The drivers I always install is something called "Gordon Gate driver", the FlashTool itself and this is enough for the phone to be recognized while plugging. Be sure to plug in the phone one time in flash mode before the final flashing so that the PC recognizes it and installs drivers, after that unplug it for a while and turn it off again because it will probably turn on, it always happens in my case when I plug the phone for the first time after f.e. installing a brand new OS and not every drivers are installed. Then run FlashTool and you can start the magic!
But, you can always disable certain apps in Settings>Apps>All. You will be actually freezing them (just like with titanium backup) but it's pretty useful. Aaaaand there are two ways of flashing recovery on locked bootloaders so that you can i.e. flash SuperSU .zip file with the app and appropriate binaries (you can find it on its dedicated thread here on XDA), that's what I'm always doing.

Ok, I have still a notebook somewhere in the corner running XP. I'll see what this one can do. If I can downgrade to 4.12, then I can rrooooot that one. At least I would not feel so naked and vulnerable anymore.
Can Flashtool make a mirror or image of the current ROM?
And thanks bunches for your helpful answer!

Here are the rough steps to downgrade:
- use a PC which runs Windump XP or 7
- install Flashtool
- install drivers (in the Flashtool drivers folder)
- download a 4.12 FTF of your choice. Nordic and Singapore seem pretty good.
- switch phone to USB debugging
- open Flashtool, click on the flash symbol and chose flashmode, follow the instructions, don't disable any of the flashing options
- after successful installation root with DooMLoRD_Easy-Rooting-Toolkit_v17_perf-event-exploit
- after successful rooting update SuperSu
- install recovery CWM4XperiaT_v8i_JB
From here you can install a rooted 4.3 if you can live with it's shortcomings, or any 4.2. I choose Pure-X-Blaster 4.2.2.

[Q] Phone bricked? Process inside.

Ok so I decided after using this thing stock for ages I was going to try CM11. Spent all day reading and trying to figure this out.
Used Krabappel guide to downgrade to .534 via flashtools. SUCCESSFUL.
Unlocked Bootloader via Sony official. SUCCESSFUL.
Backed up TA via guide. SUCCESSFUL.
Rooted via Root_with_Restore_by_Bin4ry_v33. SUCCESSFUL.
Then moved onto trying to find/install a recovery so I could flash the CM11 rom. Now where things seem to have gone awry...
Flashed advanced stock kernel v4 by krabappel2548 in accordance to this thread: http://forum.xda-developers.com/showthread.php?t=2439298
Via this command: fastboot flash boot adv-stock-v4.img
Claimed it ran through successfully. Tried to adb reboot recovery, no devices found.
Now device will not turn on. Holding down the power button resulted in a single buzz, no screen activity. Volume up+power gave the three vibrations for reset, no screen activity. Currently red blinking light when plugged in via usb.
Not sure where to go from here. Currently sitting and charging while blinking away.
Thanks for looking. This was so much easier on nexus devices lol!

Hello friend, i suppose you should try booting into fastboot mode via holding volume UP and connecting USB, see if flashtool recognizes it.
If it does, then we need to find you a pure stock kernel to install and later a recovery.
Also, what android firmware you had before flashing kernel?

Beautiful, flashtools does recognize it: blue LED and "device connected in fastboot mode"
I believe I was on 14.1.G.1.534 since I needed to downgrade to that in the first step, and I don't think any steps I took afterwards changed it AFAIK.

If you felt a vibration you are not bricked thankfully. Try flashing another ftf in flash tool and start over.
edit: oops you beat me to posting before I hit post.

Looking at my steps taken, did I mess something up? I'm not sure what I did wrong and would like to not repeat this mistake.

I found out what you did wrong.
You needed to have 14.2.A.1.136 fw to install the kernel. Read carefully what it says here.

If you messed up with the kernel, you might have to install a new one.
But firstly try what angryGTS said before me. Reflash .534 and see what happens, then i will happily help you get to a solid firmware and install CM11
Also, you backed up TA after unlcoking BL or before, and how you backed it up (recovery or other tool? )? (It's important that you have backed up BEFORE unlocking BL :/ )

That's just great news.
Your camera should not be working since you have unlocked BL and firmware version .534 . Root it using Kingo Root or such one click root programs.
And then install recovery from here .
-Use this to go to rooted 4.3 . thanks to NUT (at this point your camera should start working again)
-Use this to go to rooted 4.4 version .681 , thank NUT again (you can stay here if you want Z2 camera mods and DoomKernel and other stuff availiable to fw up to .681 )
And optional go to latest .757 KitKat using this thank NUT again , but you won't be able to do much here.
Also when you are at .681 , you might want to flash to CM11 there , check here and thank FXP team.
Have fun. And remember to read instructions carefully .

OK I got the recovery installed fine.
Is it safe to go from .534 to 1.136? Looks like NUT removed the 4.3 0.290 files that you linked today.
Do I need to be using his kernel/de-odexing at all?

Z1 Unknown IMEI, Baseband, IP, and MAC [SOLVED]

I understand there is already a post regarding another user who has had this problem. However, I believe that my circumstances differ.
I am currently running iHacker's 4.1 rom. My device is a c9603, and has an unlocked bootloader. (I'm not sure if the other user was locked or unlocked)
From the roms that I have tested, I am only able to successfully use wifi and see my baseband, etc., using PAC or a restoration of a backup made of my current rom. All I am trying to do is update from .757 to .108.
Would it be worth it to make a backup of everything, relock the bootloader, revert it completely back to stock, unrooting it, and then either root it again and try to update, or use sony's PC companion or my phone's update center to update my firmware and then root it on .108?
Thanks in advance. This has just been a persistent problem and I'm really getting tired of it.
***UPDATE***
Somewhere in all my rom flashing endeavors, I must have accidently picked up a c6903 version of a ROM or ftf. It changed the model number (according to the status in the service menu) to an 03. Something told me to pop the sim tray, and behold: Model number c6902. Flashed the correct version, and my wifi is up and running again!

Try to go back to initial firmware and then to .108

Nothing seems to be working. No matter what I flash, I loose my baseband, imei, mac, ip... The only two roms that have worked are my current one and PAC.
What the hell is going on?

Try to flash full .534 FTF
It will bring back your IMEI and baseband. I have that before (lost IMEI) then flash .534, install recovery then flash straight to .108

Alright. I have class right now, but I'll give it a try when I get home.

So... Apparently flashing anything below .757 causes my phone to bootloop... Help?

I'm still getting a bootloop. I get past the Sony and Xperia screen and then it gets stuck mid-loop of little animation they included. Could it be a broken ftf? Or just an error when I downloaded it? Because more than one of the ftf files do this.

Nope, same exact thing happened. Except this time, I only got to the "Xperia" portion of the boot logo before it decided to do another boot-loop. I waited for 30 minutes, and had it plugged in, but still nothing...

C6903 - Baseband Unknown Fix

Hi Experts,
I have searched the forum and after flashing for three sleepless nights, I am still struck with the unknown baseband issue.
The details are:
C6903
BL Unlocked & now its locked using Flashtool (DRM or TA backup is unavailable )
Currently the phone is struck in boot loop in .534
Used Flashtool ver. 0.9.22.3 & 0.9.18.6
Latest EMMA & Xperia Companion
My phone hanged when listening to the music and when I force restarted the unknown baseband showed up. While flashing I got the baseband back after flashing .518 however it hanged again after two days and I lost the BB
Now I am struck in boot loops on .534 and .518 both. I can boot into .290 successfully. Can someone please guide me to the correct method of restoring my IMEI permanently.
P.S. As per my short experience with C6903, I believe something stops the boot of .534 and .518 after first boot. Means I was not able to boot into .534 but accidentally when I flashed .518, my phone booted successfully. However now I am unable to boot into .518. May be I am missing the piece of puzzle that an expert can provide.
Thanks in advance~

Hi again, Really appreciate your help.
I have tried flashing a number of files but still in vain. What I really can't understand is .518 was the last 4.2.2 rom that booted successfully on my phone and brought my baseband back. Now .534 and .518 are both ending in a bootloop at Sony animation Really driving me crazy...
As a side note, can you tell me if the modem files in the link below are useful for this issue?

Now it isnt booting into .518 or .534.

Experts am I asking something that is un-do-able...

Guys shall I give up fixing this phone
I loved this dead beauty...

Hi, tried to flash with different cables as I don't have Sony original cable with me but the results are still the same. No luck with .534 and baseband is still unknown...
I understand this is a free community and people are free to determine if they wanna help someone or not. However I just wanna know if this is repairable or shall I just forget about repairing it. Any inputs will be highly appreciated.

I have realized that the phone does not shuts down with the power button in any bootable rom. Also sometimes the baseband does appear soon after installation but it disappears as sim is inserted. Can someone plz help me understand whats going wrong. I really love this phone...
