Xperia SP stuck in bootloop!!! Please HELP!!!
Ok here's the short story.
I made a mistake and accidentally flashed the wrong zip file and now my phone is stuck in bootloop.
It is Locked Bootloader C5303
I have a twrp backup of my previous rom which worked fine but i am not able to access any recovery, the phone just stays on the sony logo and then crashes.
I have tried fixing my phone with pc companion (which has worked before) but now when i try it the software says the update service engine for my phone is not available.
I have tried the androxyde flashtool to reinstall the stock firmware but the flashing stops and says that it has completed flashing system.sin with errors.
I don't know what to do, is there any way of restoring backups without accessing the recovery or maybe there is a way i can access the recovery.
When i hold the volume down button a green light comes but nothing else happens.
any solution will help, i don't mind returning to stock either.
Any help will be eternally appreciated.
Thanks

Give me some details
1. Windows version(7,8.1 or 10)
2.Flashtools version
FYI, if you are on windows 8.1 or above then you have to first disable driver signature verification and then proceed with installing drivers.

Hello guys,
Someone on this forum recommended to use CWM recovery to install existenz 4.0.0. When I tried to flash it it gave me symlink error 7 and I accidently rebooted. Now the phone is stuck on sony logo. Using the reset button didnt work either because it would just reboot. When connected to charger it shows a constant red light. When I use PC comp. to repair phone, it won't recognize the phone for repairs. Flashtool on the other hand does recognize the phone, but when trying to flash a stock Generic LTE ftf is gives me processing of loader.sin is finished with errors and then error flash. aborted.
Phone is C5303, FW was Generic LTE (205). System has been wiped by CWM before the symlink error.
Battery percentage was 35% at the time of using CWM recov.
Any help would be appreciated, especially as I'll be leaving for 4 weeks and I won't have acces to my laptop
Cheers
Is it Looping Again Again On the Sony Logo. If That Is The Case Either The Kernel Does not Match with Rom or The Boot Partition isn't Wipe Properly try Flashing The Kernel That Came with Exisentz or try Doomlord Kernel (depends on the version) Im Sure That will Work.

Thanks for the advice, but I managed to get the flash working (the laptop I used needed 23 driver updates so.....)
It's back to working
Help, First time flashing a ROM on a Sony phone. I have experience flashing, unlocking bootloaders and rooting, etc... but I normally do this on my Samsung phones.
So... This is what happened. I recently tried to change my Sister's Xperia Z (C6602) ROM so I could try if I could get 4k video out of its incredible camera. But I didn't have any knowledge on how it is done on a Sony phone. I researched on various sites how it is done.
First I saw NUT's dual Recovery and I downloaded it so I could get Recovery on the phone. I downloaded it and I tried using the third option which includes rooting. But I couldn't get it to work. It seemed like it couldn't root the phone properly. So I tried using vRoot (failed), tried an utility that I found while researching and I got it to root. Went back to NUT's dual recovery, installed Recovery, everything wen't excellent to this point. Sister didn't made backup so I couldn't flash the ROM yet.
Researched how to Unlock the Bootloader, saw that Sony let developers unlock the bootloader and I did it using fastboot and the code from Sony, the wrong part is that I didn't backup the TA Partition (Had TA Backup utility XDA site open on chrome but didn't use it since I thought nothing would go wrong if I didn't make a backup of the TA partition) and yes I lost the DRM keys... After this I found out that loosing DRM keys means no Bravia Engine, Music ID, etc... (I hate you SONY )
After loosing DRM keys, I was worried that my sister would kill me, so I searched trough XDA and found that you could get some functionality back from recovering the TA partition and flashing a zip from jimRnor but I needed to flash 10.5.A.0.230 ftf using flashtool. So I did it. relocked bootloader, flashed 10.5.A.0.230, booted to 10.5.A.0.230, turned off the phone, unlocked bootloader using flashtool, used recovery to flash the zip, and done.
So this is the part where I made the phone not work... (And I deleted some of my sister's photos because unlocked bootloader without backing up woopsies)
Sorry for the long story...
Wen't to recovery, tried to flash iHackers v5.2 but somehow the file didn't downloaded correctly, got some errors during installation and I turned off the phone to go check what happened that I couldn't get the zip to flash. And by turning off the phone. It somehow got corrupted or something and now the phone won't turn back on. It stayed with the LED on red. I found it strange so I pressed Power + VolUp for like 5 seconds and it turned off, and then I tried turning it on again and nothing happened. Tried different combinations and nothing would happen. lastly I tried using Power + VolUp + VolDown for 20 seconds and now it is flashing 3 times a red light on the LED. and this is how it has been for a while.
So please, has anyone had any experience with this type of problem, what should I do and what I need to learn for the next time.
P.D. Yes, I didn't know that Flashtool could do everything from rooting, backing up TA partition, unlocking/locking bootloader. I found out after I had some time using the utility.
P.D. I can't get access to neither flash mode or fastboot mode, PC won't recognize the phone.

Hahaha woops, wrong forum, going back to Xperia Z forum :cyclops:
And Btw I can't flash anything phone won't even boot to Flash mode...
Greetings, everyone.
I have an Xperia ZQ (C6503) which suddenly started rebooting itself continuously about 5 seconds after it enters the system (after the SONY or Xperia logo). First I tried removing several apps, deactivating functionalities on the short time available after each reboot.
I tried, then, flashing the STOCK Android 4.4.2 and 4.4.4. Nothing.
Did the process using PC Companion, it updated but still nothing.
Unlocked the phone (don't even know why I did that, guess I was desperate and thought this could help).
Tried flashing a custom ROM. Same thing.
As the mobile is warranty void (I bought it 2 years ago) my question is: is there still something I can do (something that they would try on the customer service, for instance) that can be attemped or my only option is to dispose of this cursed device? :/

Firstly, you've made a major mistake - you didn't take TA partition backup, as a result you've lost your DRM keys forever.
Secondly, have you checked all the boxes for WIPE'ing? (Data/system/caches)
You tried to flash custom rom through recovery or using fastboot?

Hi, thanks for the reply.
None of the tutorials I followed mentioned anything about this TA partition. What is this and what are the DRM let's? All the boxes were always checked for wiping on classrooms and I flashed the custom ROM via fastboot.

DRM keys is like a signature of the phone license. Without DRM keys your camera won't take good phones with drm keys, clear audio and bravia engine stops working either. Pushing any other phone's ta-partition backup will lead your phone to hard-brick.
Anyway, give a try to flash generic .ftf, or via phone recovery

Although it wouldn't recover the DRM keys, wouldn't this solve the issue you mentioned?
http://forum.xda-developers.com/crossdevice-dev/sony/xperia-z1-z2-z3-series-devices-drm-t2930672
I flashed several generic and specific .ftf and all of them presented the exact same result (the system didn't load correctly and the reboot loop continued). When you say via phone recovery you mean the PC Companion method? I did that, too and - once again - the result was exactly the same :/

Yeah, excatly only this way could restore all the DRM features.
About not working, I don't have any other ideas, sorry for that :/
Use Emma to flash it. (Emma is a PC software) When you have started the application connect your phone to your pc while it is turned off and while you are holding the volume down button.
You could have a corrupted partition('s) which may prevent flashtool writing the images. Possible solution is to fastboot a custom kernel and format EVERYTHING you can in recovery.
Then try to flash a stock ftf again. Good luck:thumbup:
If you have an external micro sd card in your device take it out and then reboot your device without the sd card. Worked for me.(on xperia z c6603) The sd card caused the bootloop. Why it caused the bootloop i still don't know.
And if that does not work, wipe your dalvik cache in recovery
need help
greetings
may u help me with that?
my xperia zq is with this reboot problem. i'm searching for solutions and i had not found anything about DRM and partition backup yet.

Hi Guys,
I was trying to update my Z1(C903) to Lollipop, but weirdly I wasn't able to boot into my recovery to install the pre-rooted rom. Every time i tried to enter into recovery, the phone would just vibrate and then proceed to boot the OS(I have dual recovery installed). I tried to reinstall the recovery but to no avail so I tried to flash stock FTF (14.4.A.0.157) but the process was struck at "flashing data" for a long time and I idiotically unplugged the phone after couple of hours!! And now my phone boots and i see the sony logo and next screen says "Software update failed. Connect your phone to computer and try again" And I'm unable to flash any FTF and the process still gets stuck at "flashing data".
Help me out guys as I badly need my phone for work!! Thank you!

you definitely can't enter recovery now, cause that partition would have been wiped now. try flashing again.
Hi,i'm sabing my z1 by many ways,include flashtool,xperia companion and emma.
i've flash my device my flashtool for many times,after flashing flashtool didn't response any error,but my device still cant boot up.it didnt show any screen,and i couldnt check led status(i broke its cable)
xperia companion just told me UEGetPhoneInfoMissingInfo and i couldnt go to next step.
sony emma also tell me my device is flashed,but after that my device still in black screen and without any responses.
could anyone help me?sor for my bad eng.:crying:
Does the device atleast try to boot? does it show logos or just complete blackness from the point you turn it on?
if it's complete blackness you might have some screen connector issues, I guess, that's what id trouble shoot. if it does try to boot, be sure youre flashing the right firmware, double check or even re-download the firmware from xperi-firm. It may also be decrypted the wrong way, sometimes it messes up the installation process.
did it vibrate when you hold the power button?
I also had same problem, after flashed stock fw using flashtool got bootloop. The problem started when i changed from lolipop to nougat using custom rom, all is well, last thing i did was root phone with magisk but after i decided to go back to lollipop, flash lollipop cusrom rom in twrp, got bootloop then tried flashing stock using flashtool still bootloop, no sony logo just black screen but when i flashed back to nougat custom rom using twrp it booted. Is there something needed to do in case wanted to go back to fresh stock rom?
tips,
dont too often changging rom/wiping/formating/flashing firmware
coz it will highly decrease emmc life
