Bootloop

I rooted my Xperia Z (via http://forum.xda-developers.com/showthread.php?t=2186368) and it was working perfectly fine for quite some time... now it gets stuck in a bootloop every time I try and restart it.
So, the information that I have:
The device has a locked bootloader, I rooted it using DooMLoRD's thread, linked above.
It worked for a while. I installed Titanium Backup.
When I turn the device on, it gets stuck in a bootloop.
When I plug it into my computer and hold the vol +, I get a blue LED and nothing else.
When I plug it into my computer and hold the vol -, it flashes red then green very quickly, then the LED turns off.
Nothing happens if I tap the vol+ during boot.
I'm trying to piece things together from other threads on the forum, but to no avail.
I found a thread started by someone with a similar problem (http://forum.xda-developers.com/showthread.php?p=38669779), but he doesn't say how he eventually fixed it.
Could anyone give me some advice or step-by-step guidance on how I should proceed?
Thanks!

I am having the same Issue:
Locked bootloader (Three UK network - bootloader unlock allowed:NO)
Rooted, Then installed "recovery for locked bootloaders"
Tried to flash rom, gave error code 7 for the zip, flash failed.
Now bootlooping, Cant get green LED with volume DOWN, But can get blue LED....
I think the blue LED is for fastboot, and apparently that only works with unlocked bootloaders.... Is that correct ?

Never mind, now solved
It seemed, that when stuck on the Sony logo loop, If I held volume UP and power button (to force a restart) it would vibrate once, then immediately switch my finger to the volume down key (AND HOLD) the flashtool program would recognize the device in flash mode
(even though there was no green LED on the device indicating it was in this mode, IN FACT, the phone just looked like it was completely dead whilst i flashed it with Stock unbranded firmware... but it worked)
Moral of the story .. persevere !
Hope you sort your issue too

You can recover using flash tool. Use my guide to get your ftf if you don't have one and then you can reflash it in fast tool

[Q] Can't enter recovery mode

Hi,
After updating to 4.2.2 I rooted my Xperia by ibtimes.co.uk/articles/484784/20130630/xperia-z-root-android422-jellybean-locked-bootloader.htm manual. And after successful rooting and installing some root apps I decided to install CWM recovery to backup my system. I installed the recovery following androidteen.com/sony-xperia-z-install-clockworkmod-cwm-recovery-with-locked-bootloader manual. Everything went nice and smooth and I entered the recovery mode (by pressing Vol Up while LED was green during booting) and made a backup (btw is that a nandroid backup?). The problem is that I can enter the recovery only once after "flashing" the phone with CWM. Any combination of volume keys, power key or LED will not let me enter it again later. Can anyone guide me how to enter to recovery mode anytime or fix this problem so I can use my backup if needed?
Thank you in advance!

Hey, i use to have this issue with the Z so i just installed this one http://forum.xda-developers.com/showthread.php?t=2261606 that should always let u into recovery, when the phone vibrates and the led goes green hold up. Yeah a backup is a nandroid backup. If you cant get that to work ill try help out further.

When exiting recovery did you answer the question with 'yes'? If so that's the problem. You have to answer no or have to flash a patch by doomlord.

There is no question when I exit recovery. The only option to exit recovery is reboot now (atleast I guess). What patch are you talking about? Could you provide me some link pls.
Well the dualboot is definitely last resort but I would rather fix this CWM issue :/

Yeah this happened to me also, you need to use the dual recovery instead

I don't see the point of a dual recovery. That recovery itself already contains CWM and add TWRP. What would I need 2 recoveries? There should be a way how to make CWM work somehow. Hmmm :/

Nobody seems to be maintaining the older releases of the recoveries for locked bootloaders. This is a known issue with them on 4.2.2 firmwares.
Just install the dual recovery and use only CWM recovery. You will literally notice no difference.

I've got the same problem.
so... I installed XZ Dual Recovery AND the zip file.... Flashed the Honami port (eXistenZ Ultra V1) and flashed the Dual recovery at the same time ( just as it says to do)
Now i can enter TWRP no problem, but when i push volume up it just sends the LED purple, and stays on the sony logo...
any one else having this problem???

Thanks so much for posting this, worked like a charm!

Yeah my LED never turns green, it seems to turn a purplish color after the Sony logo comes up.
This is so frustrating, is there a tool similar to odin that I can use to flash back to stock?

[Q] Tried installing ROM, phone now cannot boot. Please HELP!

Hi, I sorry to bother anyone, but I need help because my phone is not responding and I don't know what to do.
C6603, rooted, dual recovery installed, bootloader unlocked (I think)
So here's what happened. I very successfully installed the existenz ultimate rom on my phone. It was a wonderful rom and everything was going well. However, I accidentally dropped my phone and needed to send it for repair. Before sending it to the shop, I decided to do a factory reset using the option in recovery mode.
When I got the phone back from the repair shop, I wanted to install the same rom. What I did was download the rom installer and then install the zip file using the recovery mode. I went through the AROMA installer and everything, So I thought everything was going fine. When the phone rebooted, it showed the SONY logo, followed by a permanent black screen. The screen is on, it is just black.
I scoured the xda forums and I tried several things, to no avail:
I cannot enter recovery mode.
My PC cannot recognize my phone.
Flashtool cannot recognize the phone. My phone can't seem to enter flashmode, either.
I tried holding the power button and the vol. up button, and the phone does indeed restart (no vibrations), showing the SONY logo, and then I'm stuck with the black screen again.
I hope somebody can help me!
EDIT: I managed to somehow get flashmode working, so I think my phone is fine now! What a false alarm! In case this ever happens to anyone, what I did was to unplug the phone from any source of charging, then proceed to hold on the power button and vol. up button for REALLY long, I think almost 20 seconds. This managed to switch my phone off (it would keep restarting if I didn't hold in down long enough).

download stock firmware and open flashtool & ready to flash,dont connect until it say.connect your usb cable to ur phone,then reboot ur phone when display goes to black connect ur phone to pc whith pressing vol down ,then flash tool detect ur phone and it flash,sorry foe my bad english

Htc Desire 500 wont power on after flashing CMW recovery

Hi there, i have a HTC Desire 500 Dual-Sim. I unlocked the bootloader, following the steps that were in the htc developer site. I succesfuly unlocked the bootloader. After that i tried to install CMW Recovery that i found for my phone on XDA forum. I succesfuly instaled it, and i reboted the phone into CMW recovery, then i rebooted the phone from CMW Recovery. It powered off, and i was waiting for it to turn on and, nothing. When i plug it to the power suplier or to wall charger, it is just blinking a red notification light, and sometimes it vibrates 5 times, and it wont power on. I tried to change battery, same thing, tried to boot into recovery, it wont power on. If i connect it to pc, on pc it doesnt appear.
If someone knows what i have to do, please help me, or if u have any suggestions.

Bricked Phone, will not boot

Hi guys,
I was wondering what if anything I can do to unbrick the phone. Currently when turning the phone on, the notification led flashes green once, the zuk logo flashes briefly on the screen and then it powers off.
Connecting to pc with volume buttons down in any combination does the same thing. The phone screen stays black and a solid blue notification led comes up with no change.
QFIL cannot detect the phone, neither can adb or fastboot.
The bricking happened while attempting to install a custom rom. I had unlocked bootloader and accessed root on the stock system, and wanted to try out a different rom.
Thanks in advance, I just got the phone yesterday and I'm really hoping it's not permanently bricked.

Hi bobtheball,
You should be able to select recovery mode at he beginning of the boot (push volume down when you have the very first menu, and then select recovery).
I assume you've installed TWRP to flash the rom, so once you're on TWRP, you can push a new rom and try to flash again.
What ROM did you try to install?

Hi, what my original message meant to say is that I've tried every recommended procedure that I've seen. Pushing volume down while booting does nothing. The screen does not turn on and all I get is a blue notification led. Because of this I can't access the bootloader menu to boot into recovery.

Hi, your phone act as if it had not enough battery to even present the menu. Try charging the phone for half hour before trying vol-down+power button combination.
