I can't boot XZR(C5502) since i tried to flash a CWM based Rom.
1)Xperia ZR 10.5.A.0.230 ROOTED[Locked bootloader]
2)Recovery installed Philz touch,cwm,twrp by NUT
3)I have Nandroid backup also have TA backup.
4)I dont remember about USB debugging on or off.
5)I tried to enter in recovery but nothing happend.
6)While entering in fastboot blue LED lights up.nothing on screen.
Please tell what to do?
Please paste a link for ftf file(indian).I can't find 10.5.A.0.230 for C5502 indian.
Is it ok to flash nordic or some other varient of ftf.
1. Did you check if the ROM requires an unlocked bootloader?
2. Did you perform a factory reset in recovery before flashing?
If you can't enter recovery, it's likely that zip you flashed included a kernel, and the kernel flash failed because of the locked bootloader. Find a stock FTF (doesn't matter which variant, only thing that changes is the bloatware and the default language, which you can change on first setup, all Sony media apps are the same), flash it, unlock bootloader (make sure you still have your TA backup, if not, root and take it again), install recovery and try flashing the ROM again.
P.S. Fastboot only shows the blue LED, nothing on the screen, there's nothing wrong.
Good luck!

I did all of above things.But should I unlock the bootloader.I am aware about BE 2 stops working.
Will BE 2 work after restoring TA backup.

Yes BE2 will work after restoring TA Backup. I guess (not sure), restoring TA will lock the bootloader as well. Correct me if I am wrong :angel::angel:

Hey guys i know there is probably an answer in here somewhere but ihave looked everywhere and tried all possible options to get this working. After my pc companion nagging at me to upgrade i bit the bullet and upgraded to JB 4.3 10.4.B.0.569
Afterwards i then found out that it had relocked bootloader and unrooted my phone..
So i went through the sony normal way of unlocked bootloader first of all... this is where i've hit a snag.. first time the Command promp told me it had failed then itried again with my KEY and it said DONE.... now my phone was stuck in a terrifying bootloop. So i then flashed 4.3 firmware using flashtools, and repaired my phone through sony center.... again.. tried to unlock bootloader and was stuck in boot loop. I have re flashed about 4 times and tried to unlock 4 times... still getting boot loops....
Any one care to shed some light on this?
Many thanks
Chris

Is bootloader unlock allowed?
Have you tried relocking it again using flashtool?

Hey
I was playing around with 4.3 all last night and managed to get root on my Z with locked BL,
Here is how I did it..
(Locked bootloader, skip unlocking if already unlocked)
- Flash the .67 firmware via flashtool
- Root 4.2 as you would have
- Unlock your bootloader and Backup the TA partition to relock this without losing any DRM keys
- Using flashtool flash the new firmware .569 (4.3)
- Then flash Doomlords advanced stock kernel
- Boot 4.3 and power down
- Using the recover installed with the kernel flash a superSU.zip from somewhere around here.
- Reboot and you now should have root
[Locked bl]
- Reflash ONLY just .569 kernel from the FTF
- Power on and Restore your TA partition to relock your boot loader and return everything back to normal..but with some root
As for your bootloader not unlocking properly i would first check to see if an unlock is allowed
when i try to flash 4.2 67 firmware..i just got bootloop..please someone help me..what have i done wrong..i still in LB..
Wipe data when flashing.

Just unlock your bootloader through Flashtool when on newest firmware, flash advanced stock kernel, root,flash back stock kernel and re-lock your bootloader. should be working for you, and it wont take that much time :good::good:

If the warranty and features such as Bravia Engine 2 are important to anyone, please don't just follow this. Your DRM keys that allow BE2 to work and your warranty will be permanently lost.
Follow the earlier post in this thread and downgrade, root and backup your TA partition BEFORE unlocking the bootloader.

Hi everybody,
after reading about how to upgrade & root the Xperia SP on the 4.3 firmware I followed the guides to get everything set up.
Now, after being nearly there I'm stuck with a black booting screen.
Here follow the steps I did undertake so far, any help to resolve my issue would be very welcome.
I started with firmware 12.0.A.2.245 rooted with Doomlords method (flash old kernel, root, flash .245 kernel again)
1 backup contacts/messages etc
2 do TA partition Backup with Backup-TA
3 update firmware using PC-Companion
4 unlock bootloader with official sony guide
5 fastboot flash cwm / superSU
---> everything worked fine so far (phone was operational), now I wanted to get the screen mirroring working - meaning the bravia engine. So I went for
6 Backup-TA check backup integrity with dry restore
7 Backup-TA restore TA partition
last step of the restore was: reboot device, which got me to the black screen - which is where I am stuck now.
All I managed so far is entering the fastboot mode, I could confirm this working by issuing a "fastboot devices" which listed the phone as available.
Anyone got any ideas to what went wrong and how to fix this?
update: after going through the unlock bootloader procedure again the phone boots normally again ( fastboot.exe -i 0x0fce oem unlock 0x[...] ) . Now the last problem is getting the TA partition back.
Is this even possible while keeping root?
Flash stock kernel .266 before restoring TA partition.
go to flashmode and flash the kernel.ftf, links of which can be found by searching.
this problem has been posted as FAQ in Bootloader unlocking relocking thread.
Thanks! I'll try this. I thought you only had to reflash the stock kernel if you wanted to relock the bootloader
I'm unable to flash or restore a stock based or stock ROM. When I do, I get a screen at boot up that says the update failed, try again. If I try to flash a stock ftf, it stops at system.sin and gives a header error.
I am able to flash kernels with fastboot and can flash and restore Slimrom, CM 11 and CM 12.
In have a c6903 with an unlocked bootloader.
Try reinstall drivers, update/reinstall Flashtool.
Maybe a bad recovery? Corrupted FTF?
Try this too:
Open windows task manager, go to process tab and kill adb.exe, reboot windows. I don't know if this will work but its worth to give a shot.
Thanks. I've tried 2 ftfs but I'll try a third after doing the other things suggested.
Any news tgilmore16?
Didn't work. I'll try again tomorrow on a different PC.
Fixed. Thanks.
The steps were:
1. Relock bootloader with flashtool
2. Flashed a stock ftf but excluded system.
3. Rooted
4. Installed NUT's dual recovery
5. Flashed superSU
6. Rebooted and saw I had root
7. Rebooted to TWRP and saw I had TA as an option in backup and restore. Did a backup and have been running ok since.
Not being an expert, I'm guessing everything had something to do with the partitions.
Good, but have in mind that Flashtool and TWRP doesn't backup/restore TA DRM keys, just the partition.

I think you're right, but I think the missing partitions had something to do with it or something in the partition tables were possibly corrupted. I haven't tried to restore the keys but being curious, I probably will give it a shot.
Ok! I am stuck at the sony logo then a screen appears saying that something went wrong while i was updating the device.
all I did was flash a wrong recovery image for my old phone & then this happened
what I tried:
1. tried to update from the flash tool (didn't work)
2. tried the sony PC companion & it didn't work either, it either says that I have modified software that can't be updated or says that my system doesn't have any updates
my phone is ZR C5502, bootloader was unlocked when I flashed the wrong recovery image.
Please help me I need the phone to work
Thanks in Advance

Did you take the backup of DRM keys and TA partition while unlocking bootloader? Sony PC comp does not support unlocked phones. you will have to restore the DRM keys and TA partition.
If you have lost both of these, then flash custom kernel and stock or AOSP based ROM using flashtool. search in forums for more info
Thank You!
I Had the Backup & tried Relocking the Bootloader but the PC companion couldn't help me, anyway, I flashed a flash custom kernel and stock ROM using flashtool, thank you so much :good:
Hey there.
I'm in need of some help.
Last night, I was installing https://forum.xda-developers.com/z3-compact/orig-development/cr-5-1-carbonrom-t3529766 on my phone, going from stock 6.0.1. The steps I followed were:
First unlocked my bootloader. Phone boots up fine.
Flashed twrp and booted it. On twrp, the zip I was going to use gave me a error 7. Followed the instructions regarding that, and removed the get.prop lines.
Now it flashed without any errors.
Rebooted phone. It's stuck on bootloop (The Sony logo shows up for a split second and then starts again).
Tried relocking bootloader and flashing stock ftf, but it's still stuck on bootloop. Also tried flashing EliteKernelV3 but to no avail.
I have access to flashmode and fastboot, but can't get into recovery nor offline charging. Think messed up my partition table, and I can't figure what to do. Searched a lot on the forum, but usually the similar problems are solved by flashing stock ftf, wich is not happening to me.
Would be really grateful if some could shed some light on my case.
EDIT: I made a TA-backup prior to flashing custom ROM.

After I flashed the ROM, I did a factory restore.
Unlocked bootloader, flashed with EMMA, and it is still stuck on bootloop.
Thanks anyway.

Try flashing an older firmware like KitKat it maybe has the Z3C partition table inside of the ftf,but the MM firmware doesn't.

Indeed KK has partition table on the ftf, but it is still stuck on bootloader. I guess I'll contact Sony to see if they have a way of fixing it.
Thanks guys!
