Xperia Z repeats reboot after root - Xperia Z Q&A, Help & Troubleshooting

Hello,
today I rooted my Sony Xperia Z.
After unlocking the bootloader I did the next steps with Z_DooMLoRD_CF-Auto-Root-ported_FW-350.img and Z_DooMLoRD_insecure_FW-350.img.
After that I worte "fastboot reboot" to reboot the phone.
My issue now, is that the phone boots until the "Sony" writing , simultanously the red led in the upper right corner appears, then the display is black again and the LED off.
The phone repeats this now endless....
I hope you can help me!

What's your FW version?

Sorry, but I dont know, I just rooted it.
Or is there a way to find it now?

Connect it to your pc and open flashtool, it might tell's you what fw your on (not sure though as I haven't used it in some while) If not you have to flash either a stock rom, or another kernel with inbuild recovery and then a custom rom, depending on what you want.

[Q] Sony Ericsson text won't disappear

hi, I am having trouble booting my mothers' X8. She was using mini cm7 and it was starting to be very slow so I backed it up and flashed it again. flashing was completed successfully but when I tried to boot the phone, the Sony Ericsson text did not disappear. I left it running whole night but nothing happened. I can't even boot to xrecovery. What should I do now? Is there any way I can get the phone working again?
thanks a lot!

so I downloaded the stock kernel and flashtool, but the app won't recognize the device. it still shows that I should hold back button on my phone while plugging the cable. I was holding the button for about three minutes but nothing changed. what should I do?
edit: oh and the red LED is flashing.
edit2: nevermind, battery was drained. now I just need to find drivers for my x8

It's just soft brick so you should have flashtool and some ftf files for your device maybe stock firmware and baseband update so you can unbrick your soft bricked device for any time. Just enter the flash mode and flash it! That's it! Just some advice for you
PS. Don't say thanks. Click "Thanks"

[Q] Bricked my phone... but weirdly.

Hello... I seem to have bricked my phone but it's a weird brick. I tried a new ROM since I was having problems with my old one, and it got stuck on a reboot loop. I just didn't know what to do and (very stupidly, in retrospective...) just wiped the system partition. Now of course I can't access xRecovery (to be fair, they warned against doing that) and I don't remember if I had CWM installed at the time.
The phone was rooted, stock kernel.
Now, I can boot the phone and get stuck on Sony Ericsson logo... so far so good. But when I try to get it into flash mode, it won't boot. Is there anything I can do to un-brick it?
I tried Flashtool, PCC and SEUS. But since I can't boot into flash mode, it doesn't work.
If there's any more info I can provide please tell me and I will.
Thanks a lot.

Yes, I tried Flashtool, SEUS and PCC. I un-bricked it from soft bricks quite a few times. But I can't now because I can't boot on flash mode.

Dude looks like it just a soft brick ... u can download the official firmware for this model and try to flash it from flashtool..power off phone, hold back button key left on right side and connect the USB to PC at the same time,... PC will detect your phone and turns to blue light..
In my case i totally ****ed up when i tried to unlock the bootloader. Now my phone is totally dead.. can't go to falshmode, phone won't start at all... but in your case at least your phone is turning on in sony ericsson logo which means its just a soft brick ...

That is called booting to flash mode, and that's what my phone can't do... the main reason I'm posting here.

if you have unlocked bootloader.
try this. it should go into flash mode this way.
launch flashtool. select some kernel. alfs or nAa.
take the phone battery out. connect the usb and then put in the battery immediately.
it should start flashing the kernel. then you can use the cwm integrated in the kernel

I imagined xD. I just tried with that too.
With flashtool, it gets stuck on "Reading device information" (I wanted to post edit and post this but the forum didn't let me xD). I'll let it try a little bit longer, but it's been a while.

if it fails for any reason then try flashing older baseband and then try seus. i dont remember if flashing baseband requires unlocked bootloader but its worth the effort

Youve wiped your /system so your phone is blank.
Get flashtool and an FTF and revert to stock then root, recovery and flash custom rom again.

As soon as you wipe /system your phone is basically without recovery/OS so unrooted. While the recovery is active and in memory this is fine but if you reboot then you lose even that. Root is all about the OS which you dont have.
FTF files can be found in the android development forum.

If you have flashtool.. Download stock ftf from http://forum.xda-developers.com/showthread.php?t=2311964 and place it in Flashtools>firmware. Connect your device in flashmode( Volume Down and connect). Click on the Lighting Button> Flashmode and flash. [ BACKUP YOUR INTERNAL MEMORY AS IT GETS FORMATTED]
But note that you will lost Root Access. You have to root your Xperia SP again. And if you have unlocked bootloader then it will remain unlocked. No need to unlock again.
---------- Post added at 06:52 PM ---------- Previous post was at 06:00 PM ----------
Forgot to mention to power off the device if stuck in bootloop.
Take off your back case. Take a pen,pencil or similar object. Hold the small yellow button at the bottom of the device with the nib of pen or the object you are having. Hold that button until the device vibrates thrice.
Thanks all for help and support it works fine now ;D but again i have to root my device. Maybe someone can tell me the fastest/easiest option to do this. I'd like to do this with locked bootloader. Last time I used V-Root. Any suggestions ?

Good to know that your device works fine.
But Remember You have to install CWM again as well as Root your device again.
This is the Kernel which install CWM as well as Root your Device.

With your phone off and unplugged, setup Flashtool to flash the FTF of your choice.
When you're ready, press and hold the volume up button, and then plug in the device.
The LED will flash red and green quickly. You are in Flashmode now. Flashtool should be working away. Leave it plugged in until prompted to restart (watch the log).

Thanks for reply, but I dont have any led light, thats my problem. When I want to do something, like get into Recovery, I restart my phone and I dont have any LED light, when I plugging in the device - same.
I have the same problem buddy but if you have a computer just install a recovery by downloading the file from NUTS web page (search for dual recovery for z1) and let the PC detect your device. In command prompt it will ask you to hit option 1 or 2 and it's pretty self explanatory. Don't worry about the Led, just flash the recovery using your computer.

[Q] Cannot get Xperia SP into recovery.... Stuck on Sony Logo!

Hi there,
I'm still very new to this so I'm gonna try to describe this the best way that I can.
Basically I have a Xperia SP C5303 and I was getting frustrated of it being slow and keyboard failing to pop up - these are just a few of the issues I had with this phone. I had previously downloaded the 4.3 update for the phone. So basically I thought "let me try to update it to 4.4". So I google the update and put in on the SD card on the phone. So I enter recovery, and follow the instructions (wipe all user data) and then I go to install the "cm-11-20150412-NIGHTLY-huashan.zip" It then came up with an error saying it could not be installed. So i'm panicking here and did the mistake of restarting the phone. Now the phone is stuck on the Sony logo and I cannot get it into recovery no matter pressing the up and down volume button.
Can anyone please help me? I do not have a phone now and as a man I am not afraid to say it made me shed a tear or two a bit.... But anyways, if you can please help. Thank you you wonderful people.

Hello my friend, I assume you´re on locked bootloader, right?
If it is so, you flashed the wrong Rom. Anyway, don´t panic - not a big problem.
When you have restarted your phone, you started it without any system. No wonder, that doesn´t work
Ok. let´s go:
First, you have to flash a new stock Rom. Go here http://forum.xda-developers.com/showthread.php?t=2311964
Second step - root it and install a recovery. Got to the thread of our Guru Doomlor http://forum.xda-developers.com/showthread.php?t=2354704
read the steps carefully, so you can´t make any mistake!
Step three - on locked bootloader you can only flash a Rom for LBL!!!
If you want a CM11 Rom I recommend bagyusz´CM11 Rom from here http://forum.xda-developers.com/showthread.php?t=2735975
If you will follow all the steps you will have back an excellent CM11 Rom with much, much fun.
Goodl luck, reinipic.:fingers-crossed:

Hi, what do you mean with "tried all the steps"???
Did you flash a stock .ftf Rom with Flashtool?
It is nearly impossible to brick the XP.

I've downloaded the .ftf file onto my laptop, but getting my phone to open the file is an issue because when i connect the SP onto the laptop, it switches on the phone but has been stuck on Sony logo for the past couple of hours. The Recovery_SP.zip and DooMLoRD are both not picking up the phone as plugged in on USB drivers.

Now you can start flashing
