OK, I decided to put a custom ROM on my Z2 today. I did not unlock bootloader, but installed NUT's Dual Recovery. It booted, installed ROM fine. I decided I wanted to reinstall to change some settings, wiped data and davlik, rebooted (by accident), and now I'm just suck at SONY logo on boot. Please help, not sure how to fix this. I can power off by Power Button + Volume Up, or the red button on left side. I just want to get it back into recovery so I can reflash, or whatever I need to do to revive it. Searched around, not finding much to fix it. Please help!

OK, I at least got that far using proper instructions, still doesn't boot though, stuck at SONY logo.
Nevermind, it worked now. It was telling me some weird instructions, had to have it in fastboot, unplug and plug back in again without doing anything. It's booting now. Why would this happen? Maybe I just need to unlock my bootloader?

No, it has nothing to do with unlocking your bootloader. If you were using flashtool you probably didn't plug it in in the correct mode.
As for unlocking your bootloader, read the instructions on any ROM's OP. It will tell you whether it needs an unlocked bootloader or not. Sony stock based ROMs sometimes do and sometimes don't. AOSP based ROMs do need an unlocked bootloader as that is needed to flash a custom kernel. If you do want to unlock your bootloader, read up on how to root your device first without unlocking and then read up on how to back up the TA partition of your device. This partition is effectively your warranty and contains the DRM keys to all of Sony's proprietary software. If you unlock your bootloader without a backup, you lose your DRM keys and they are non retrievable. Thus, if you want to send the device off for a repair, without restoring the TA partition you cannot restore your warranty and it will be declined. Having your TA partition backed up means that if you ever need to send it off, you can restore it and this locks your bootloader and reverses any DRM key loss.
If you have any further questions please ask before doing anything. We can only help answer questions if you ask them :highfive:
Please post questions and help in the Q&A/Troubleshooting section. You will receive replies much more quickly if you do so.

Shameless crosspost from the tutorial-thread for installing Cyanogenmod on the Neo over at the Cyanogenmod forums.
Hi! I'm quite new to rooting and flashing my device (started reading and doing it yesterday), but I really want to make it work now, but I can't seem to get it working.
I have no problems rooting my phone or installing ClockWorkMod, but I can't seem to get it to run neither a custom kernel nor a custom ROM.
I have a SE Xperia Neo, and have both followed the mentioned tutorial, and tried other methods (some pulled straight out of my ass) to flash my device, but no matter what I do, ecxept flashing to a stock ROM of Android (I think that's what it is called?), it always freeze on the Sony Ericsson logo, right after the FreeXperia logo, and I have to do a hard shutdown (pop out the battery and replace it again) to get it to do something else. However, when frozen, both Flashtool and SuperOneClick is able to root the system at this point, so it isn't frozen, but it never goes on doing something, either. I guess it's just trying to boot a (incompatible) ROM.
My bootloader is unlocked (I just checked).
I've tried following the mentioned tutorial with both a phone flashed with 4.0.2.A.0.42 and 4.0.1.A.0.283 (read somewhere those were the best supported or best to use for this?). I've tried flashing the boot.img from the Cyanogen-zipfile to the phone (went well) on both; I've tried repeatedly pressing the volume down key both on boot and on the FreeXperia screen; I've tried to flash boot.img to the phone, rooting i, using both SuperOneClick and Flashtool then installing the ClockWorkMod (as I couldn't get to the recovery screen). And, I've followed the tutorial between two and three times with both 4.0.2.A.0.42 and 4.0.1.A.0.283. I have no idea what to try next.
Does anybody here have a clue for me? Should I try flashing with another Android version running on my phone (if so: which)?
How exactly did you checked if your bootloader is unlocked?

First I tried to unlock it again with fastboot, which said it was unlocked. But I also opened the dialer and pressed *#*#7378423#*#*, Service info -> Configuration, and at the bottom it said "Bootloader unlocked: Yes.". Is one of the methods prefered over the over?

No, it doesn't say that

And that only means that your phone wasn't locked by operater, and that your fastboot is unlocked, but not that your bootloader is unlocked

Anw, since you see free xperia logo that means you flashed kernel(or at least boot with that kernel) with success.
Q1: You say you pressed volume-, have you tried with pressing back repeatedly? or by taping on screen? or repeatedly pressing power button?
Q2: show me instruction which you used to flash kernel?
Q3: you said you installed CWM trough flashtool, does that mean you manage to enter CWM eventually or not?
Q4: show the link of what you are trying to install.

I did not install CWM through Flashtool. However, when not following the tutorial I mentioned, I installed CWM Recovery using a modded installer. IIRC it was modded by DoomLord, but I can't find the link for it. When using a stock ROM, I boot into CWM Recovery with ease by repeatedly pressing the volume down key.

And, by the way, Madfysh, thank you for caring enough to taking your time to try and bend your mind to understand my problems. If I knew your reddit username, I'd stalk you and upvote everything.
Only things I can think of is:
1) make 100% sure you are writing fastboot flash boot boot.img and not fastboot boot boot.img
Sometimes people write wrongly without noticing, and after few posts they realize they wrote wrong instructions.
2) try repeatedly pressing other keys, each time your phone starts with that kernel, try pressing one key.
3) try FREEXPERIA RELEASE INSTALLATION from same link.
I will try everything you've suggested, Madfysh, and report back after trying.

As the download link was not working/outdated, I tried another kernel/ROM-combo, that worked. Now I'll try and see if I can find a ROM that I really like and use that instead of Cyanogenmod, as it looks like it don't play well with my phone at this point. Thank you for taking your time to try to help me, Madfysh. You're the best!
Hello guys, I'll describe my situation here before getting dirty with the phone:
Phone: Xperia Neo MT15i
Android Version: 4.0.4 (Via PC Companion)
V. Kernel: Stock 2.6.329-perf compilation 4.1.B.0.431
A nice detail here, I had signal
The mobile was bought "free", I had different SIMs from different companies and that worked nice.
I unlocked the bootloader via the official way from the sony web, it went well. (I read in some posts that I lost my DRM, it scares the s**t out of me because I really don't know what is that)
Then I entered fastboot and type fastboot boot boot.img, this boot.img is the NeoRecovery.img, which contains CWM.
Then i insalled de super user.zip for beeing root, AND THAT'S IT.
Now, I have my rooted 4.0.4 with NO SIGNAL.
I insert my PIN code, then I get prompted with the Language selection menu, and then the following message:
Please insert SIM card and restart your phone
All this steps OVER AND OVER AGAIN
(I've tried with 3 different SIMs, and I can't even register in my network)
I've searched a lot, and don't know what to do here. Some help would be nice!
Thanks!!
Not sure about no signal problem, but interesting is that you get setup wizard every time, if I understood you ok.
Go to settings->backup&reset-> and do factory reset, it will wipe your data, so make backup.

Hello Madfysh, I wiped my data a few times (also from CWM) and still nothing
The worst part is that now PCC won't fix my device, so I don't know where to head next.
Should I try a custom kernel..? Should I re-lock my bootloader (how?) and trying from PCC?
Thanks!
EDIT: After some loops, I decided to flash my phone with the MT15_4.1.B.0.431_Global.ftf file using flashtool verison 0.9.0.0, I think that contains the ROM only, because the kernel that I'm using is still the same. Nothing new I'm afraid
well, you can relock it, and use PCC. Always good step in solving the problems, first try with stock reflash, then move on
How to relock, you can find in Neo V dev section, sticky thread.
Many thanks for the information, I'm going to try it right now.
Excuse me for asking but do you know if re-locking may cause brick / not entering fastboot again / not beeing able to unlock again?
Thanks!

Flashing .ftf didn't help, but re-locking did, right?
isnt relocking done by flashing ftf alone?

If that was toward me, by .ftf i meant on entire .ftf which he mentioned in his post, not on the relock .ftf.
Hello,
I just got my Z ultra yesterday. Set up everything, installed dual recovery and rooted, backed up TA partition, backed up via Titanium and Helium, and then through recovery, and then attempted to flash PA 4+. Now my phone will not turn on. When I press the power button it vibrates once but nothing happens. I can get the blue led to turn on for flash mode but screen is still off. I read through the PA 4+ and did not find anything, how can I fix it, will it be done with Flashtool? This is the first time I have had problems as I could usually always find a fix on the forum for my note 2.
Edit: Sony C6833 running kitkat .108 with a locked bootloader. Backups are all on the EXT SD Card.

Thank you, I'm glad to see that I'm not the only one who made this mistake. I will post as soon as I get home and am able to flash. Right now I have been thumbing through all the threads and had just come across using Flashtool and the stock FTF to get it bootable again. Thank you for the quick response.

Posting update, was able to flash and boot. Phone is back up and running.:victory:
You didn't research before trying to flash a custom ROM did you?
I did the same damn thing day one but I got lucky. Hopefully this will show as a lesson to others that just jump in. But then again I guess that's how all learn.
Well I read one post that stated that as long as you kept the stock kernel you could flash. Just didn't realize only some roms worked. Also everything I'd different from my old Verizon note 2.

Hi Guys,
I have a Sony Xpeia Z2 which has a locked bootloader. I managed to get into TWRP recovery using the dualrecovery APK and tried to install CarbonRom custom ROM and Gapps. All installed fine but when I rebooted the phone nothing happens now. If i keep my finger on the power button it just vibrates once every 5 seconds and thats it. I can boot it into fastboot but that is it. I can't boot into recovery as it was not flashed as bootloader is still locked and is set "unlock allowed=no"
Have i just killed my phone? is there a way to return back to stock or flash a different custom rom that will work?

you need to unlock your bootloader to flash carbon rom
you can use this guide to recover your device

http://forum.xda-developers.com/showpost.php?p=53220435&postcount=4
just a note, instead of holding volume up and power you can hold the red power switch above the simcard in the port on the left side of the phone, its a red reset switch, its quite small
about pt 2 is where it asks

Hi guys. I've been being a XDA reader for a long time so, today I decided to register in this great community.
As a Xperia phone owner (actually, I don't own a Xperia Z2 but I thought I rather post this question in this subforum since it's a general Xperia phones question and Z2 subforum is crowded, lol), I would like to know which flashing method is more effective when trying to recover a bricked phone: 'fastboot mode' or 'flash mode'.
I ask this question because my Xperia M2 is stuck in bootloop (I can power it on and both Sony and Xperia logo appears but when the "purple waves screen" appears, handset does nothing else, just keeps showing that purple screen with waves in motion).
I've been trying out to flash a .FTF file with Flashtool but to no avail. Once process is finished and reboot my phone, it gets stuck at same "purple waves screen".
The problem is that the bootloader isn't unlockable unless I send my phone to Sony Technical Service to change "Unlock Bootloader Allowed" to Yes (they can do it for free since my contract with carrier is finished). But before doing so (in order to enable fastboot commands), I would like to know whether or not it worths sending the phone to Sony. So:
Is there any chance I could recover my phone trying out to flash a ROM with fastboot commands enabled (bootloader unlockable and unlocked) knowing I wasn't able to recover it with 'flash mode' (flashtool)?
If so, which steps should I take? Maybe extracting .SIN files from within .FTF file? Any help would be very appreciated. Thanks in advance.
PD: Before flashtool, I also tried to recovery the phone using official PC Companion, but with same result as flashtool.
You cant realy recover a phone through fastboot (aside flashing a stock kernel.sin)
(asuming a custom kernel on LB is the cause)
There are many reasons for a brick but the most common ways of unbricking would be forcing off the device and flashing a FTF which can only be done via flashmode

Thanks for your reply, Envious_Data. If I flashed an entire ROM (.FTF Stock ROM file) with flashtool, kernel is supposed to have been replaced with stock one after the process, isn't it?
What do you suggest to do further? Firstly, I tried PC Companion. Then I tried Flashtool. My next step was going to be trying to unlock bootloader to enable fastboot commands but, from what you said, maybe that's not worth it... Any chance I could recover my phone myself without sending it to Sony? If I send it to Sony to convert BootLoader to Unlockable ("Unlock Bootloader Allowed: YES"), will the phone be recovered "collaterally" (maybe, to do so, they do a fresh ROM install and that fix the bootloop problem, I don't know, what do you think)?

They wont do that, they will refuse to help you unlock your bootloader unlockable
I recomend flashing a FULL FTF because it should fix your device if it isnt suffering hardware damage.

If your contract with carrier is finished, Sony can and, in deed, does convert the bootloader status from "Unlock Bootloader Allowed: NO" to "Unlock Bootloader Allowed: YES", but you have to send your phone to Sony Technical Service. From what I've been reading, in that process, techs do some flashing jobs, so maybe phone gets recovered collaterally... Any clue?
Have you tried waiting a bit for it to fully boot up? Seems like you just came from flashing and booting up the phone may take a while. I tried flashing LP rom earlier today, and it took me 20 mins before the phone boots up completely.

Hi das.dian24. Yes, I've been waiting for it to boot up more than 20 minutes, even 30 or 40 mins, but no luck. It's so weird. I can't believe I can't fix this bootloop problem flashing the phone either with flash mode or with fastboot mode. I don't think that's a hardware problem.

Now thats really weird, i only experienced this kind of bootloop when i mistakenly formatted /system and forgot to flash any rom after that. Maybe not a hardware problem since the phone boots up til bootanimation and the fact that u can flash roms successfully.
