xperia sp stuck in bootloop! - Xperia SP Q&A, Help & Troubleshooting

hello guys im new to sony, and got my xperia sp just 1 week ago!
here's what i did.
1. rooted using towelroot
2. installed super su from play store
3. installed twrp with a tool,
4. copied xperianzev3 and gapps to sd card
5. backup
6. did wipes and flashed rom and gapps via twrp
everything went fine and the rom was good,
i was stupid enough to boot into recovery and restore the backup i made( boot.img also)
still the phone was working but gapps were crashing repeatedly!
so i booted into recovery but there was no recovery! i installed the recovery again with the tool
now the phone is stuck in bootloop, is constantly rebooting ( first sony logo, then xpria then the color splash, then reboot!)
please help me with details! i know nothing about flashtool , fastboot!
my phone is c5306 factory unlocked, locked bootloader!

Download the stock .FTF file for your Xperia SP model. Download Flashtool by androxyde and also install Xperia drivers for your Windows pc which come along with the Flashtool.
Place your downloaded stock .FTF file inside (C:/Flashtool/Firmwares) here C is normal drive where Flashtool installs you can respective drive with which you want. Then make sure your phone is switched off.
Open Flashtool and thn hit smart lighting button on top left and from there select flashmode and click OK.
There you will see your downloaded ftf if you placed it under firmware folder.
Now just select it and click flash and wait for the Flashtool to load files. Once it's done then you will see a menu popping up saying to connect your device. With device switched off press and hold power button and Volume down button to connect it into flashmode and that's it wait for the flashtoool to do the job. Once it is complete then disconnect your device and start it and wait until it loads.
Hope I helped. Hit thanks if I did

That seems to be a firmware error. Try redownloading the stock Firmware again or try another version

Ok so im sorry to say that the Firmware should be the problem. I suggest you download the stock FTF file for Singapore, my country as it seems that your stock FTF file might have been uploaded wrongly. There is also a chance that your phone might have a NAND error which means that your hardware might have a hardware error.

If youre still receiving errors, you might need to send it for repair. Im not sure whether you'll still have your warranty intact though...

sorry bro, same error! system.sin

Well then I guess you can either contact a dev here or you can go to your respective sony repair centre to request for a phone repair although i doubt they will repair it for free...
Sorry for the loss

While you are flashing the firmware in the right side you will see exclude box just click on system.sin and try again it'll surely work

Your phone need to be shutdown for the flashmode (download mode) so the USB debugging has nothing to do, you just need to shutdown the phone, press the - volume button and plug the USB cable in same time when it asked.
Have you tried to connect the device via fastboot, flash a standalone kernel with a recovery included and flash a rom via recovery?(DoomKernel for example).
Maybe this is a bit too much information if you are new to unlocked bootloaders, but all the steps are well detailed on development section of the forum, search a bit for fastboot instructions and drivers needed, then head on to DoomKernel thread for a standalone kernel. And sorry I cant give you links and stuff, I'm on the phone and it is quite a trip to provide all the links.

Restore it with Sony Update Service and resize your ****in photo DUDE!
PS: Do you really destroyed your screen
I would say its drivers too; have you tried reinstalling flashtool and drivers.
Does your pc make a sound when you connect your phone in flash mode; does it recognise it?
Also, may be a weird one but, is your battery charged over 50%.
If you want to use SUS or PC Companion you have to relock your Bootloader first by restoring your TA partition considering you backed it up

If you backed it up with Backup-TA then you can run Backup-TA again while your phone is plugged in and select the option to Restore TA.

[Q] Phone keeps waking up while in flashmode

Hello. I'm trying to root my device by downgrading it first. So i need to flash the rom. I had my phone in flashmode. But in a minute or two the phone will wake up. And i can't continue my flashing because of that. Anyone know supposed to be the problem? Sorry im noob at this stuff
Don't connect ur phone in flash mode until flash tool asks for it. The moment flash tool indicates u to connect ur device on, only then connect it in flash mode. Once u load the ftf in flashtool, it takes a min to process the files after which it notifies for u to connect ur phone. Cheers

Yeah i did redownload it. It's still the same. My XZ is 10.4.B.0.101 and i'm trying to downgrade it to 10.3.1.A.2.67. And my device is 4.3. Don't know if it's the firmware that i'm downgrading or what..
Next time please post in the Q/A section which is DIRECTLY BELOW the general section.
Also tagging a post as a question in the general section will bring up a prompt telling you it doesn't belong here if i recall correctly..

Download the ftf from other place. Maybe the site you downloaded from has uploaded a damaged ftf:
And for your first problem try reinstall flashtool and when the device turn on when you in flashmode hold vol+ and power button for 15 seconds
Hope that helped:angel:

[Q] Rare Case - Red LED always on while screen is on

Alright. My brother bought a used Xperia Z about 2 weeks ago. After using it some days, suddenly this happened. The red LED always stays on while the screen is on. And this is a rare problem. I don't see any problems like this before in XDA. The phone is not rooted nor the bootloader has been unlocked. Can someone help fix this problem, or tell me what partition is damaged, etc? I can't confirm this is a HW damage coz it's not dropped, or punched, etc The red LED acts normally if the screen is off (e.g. while charging, notification, etc).

Greg is trying to help you mate.
And he's right, there's a time difference and you have to wait for guys to see your thread...
Check do you have latest flashtool
Check do you have correct drivers
Check is your ftf corrupted (download a new one)
, hard restart your device (vol up+power).
Open flashtool and hit start, wait till flashtool prepares fw and ask you to connect device.
Then connect device.
If that won't work, try to download another ftf file...
Maybe you have corrupted ftf and that's causing a problem...

Uff...
Are you sure you restored right/yours TS backup?
I have a friend who restored Z1 TA backup to Z2, this things happen so who knows...
It's really odd if you restored your backup on stock fw and something like that happened..
Now I realized you wrote "I had flashtool problems..."
I thought you have problems in flashtool now, that's why I said try with another ftf or another flashtool version...
If you got that, and you did, while you were flashing ftf....I believe you are, unfortunately, right, this is hard brick.
BTW - which firmware you tried to flash?

you need to be on a stock kernel if you relock the bootloader.
You should have flashed a stock FTF immediately after relocking and before restarting.
The solution is to flash a stock FTF
and you have not done this yet

I tried to install magisk using bridge approach
and ended up with something that will get to just bluelight ( flashboot ?) mode . I am downloading a stock T-Mob FTF. J-FYI this is an operator locked boot loader. I dunno - is it poss to permanently unlock it and install Cust ROM ? I want to :
-- Recover my data from the dead prev . install
--Have a ROM ( stock or custom ) with Magisk installed.
My plan :
-- Flashtool install 4.4 FTF

XPERIA SP C5303 Bricked..Tried many ways but couldnt find solution..Please Help!

Dear Members,
I am new to XDA and my problem brought me here to discuss with you guys.
Few Days ago I tried to update my Xperia Sp ROM from Jelly Bean 4.3 to Lollipop 5.1.1. While updating and installing Rom from SD card I rebooted my device that didn't start again.
Current Situation:
Device doesn't turn ON.
Power + Volume up Key-->Blue Light (Blinks) [ Not connected to PC]
Power + Volume dwn Key-->Green Light (Blinks) [ Not connected to PC]
While connected to PC, Green status Light continuously Remains ON, Flashtool(Emma) detects the device and displays message "Locked Phone Detected". Flashtool Correctly Displays device information but in faint colors with cross sign.
Using back hole power off button (pressed for 10secs) then pressing Vol up for 10secs and connecting with PC, PC detects the device.
Before Writing this thread I have tried all possible ways by following the methods and suggestions provided on this platform but couldn't solve the issue. Please guide me to solve this issue.
Thank you all in advance for your precious time.
Regards
Your bootloader seems locked(as emma suggests). If sony pc companion repair option doesn't work for you then I don't know... Maybe you hard bricked it but that's quite unlikely.
Before you flash a custom rom,you need to have a unlocked bootloader first. It's not bricked,you just need to unlock bootloader and then you can flash any custom rom you want.

Your bootloader seems locked(as emma suggests). If sony pc companion repair option doesn't work for you then I don't know... Maybe you hard bricked it but that's quite unlikely.

Yup, Thanks for your reply
Emma shows Device is Locked and PC Companion neither recognizes the device nor proceeds the software repair.

Yes. The method I followed to install custom ROM was without unlocking the bootloader.
Could you please suggest me the way how to do that..
Thanks for your reply
Power off the phone and try connecting usb while pressing volume down. pc companion should detect it. then try repairing. (If not something's very wrong)
For unlocking bootloader see this: unlocking bootloader
If you unlock it, flash twrp.img with fastboot. in the thread above there is a fastboot package. command is: fastboot.exe devices (if detected then) fastboot.exe flash boot path/to/twrp.img
and then via twrp flash ROM.

Try also flashing stock ftf with flashtool, use version 0.9.18.6 and install drivers properly
Download stock ftf from here http://forum.xda-developers.com/showthread.php?t=2311964
While powered off press volume down button and connect usb for flashmode., exclude TA.imgs and flash it

Dear Members,
I am new to XDA and my problem brought me here to discuss with you guys.
Few Days ago I tried to update my Xperia Sp ROM from Jelly Bean 4.3 to Lollipop 5.1.1. While updating and installing Rom from SD card I rebooted my device that didn't start again.
Current Situation:
Device doesn't turn ON.
Power + Volume up Key-->Blue Light (Blinks) [ Not connected to PC]
Power + Volume dwn Key-->Green Light (Blinks) [ Not connected to PC]
While connected to PC, Green status Light continuously Remains ON, Flashtool(Emma) detects the device and displays message "Locked Phone Detected". Flashtool Correctly Displays device information but in faint colors with cross sign.
Using back hole power off button (pressed for 10secs) then pressing Vol up for 10secs and connecting with PC, PC detects the device.
Before Writing this thread I have tried all possible ways by following the methods and suggestions provided on this platform but couldn't solve the issue. Please guide me to solve this issue.
Thank you all in advance for your precious time.
Regards
