Hi, I believe that I have returned my phone back to stock.
But I'm frankly not sure if the phone is still rooted, and if the boot loader has been relocked.
I did use the TA Backup program to restore my DRM keys.
Then I simply used Flashtool to flash the latest ROM .108 onto my Z1C.
Will my phone be accepted for warranty repair?

If you did this you are ok for warranty.No need to worry...
Thanks! I appreciate the reassurance.
so the TA isn't related to stock rom version? or in other words, it isn't important if you backed up the TA while running 757 rom, it's okay to restore TA and flash 108 for exanole?

just to be sure,.. restore TA on the version you made it from..

will bravia engine work with this?
i was on 6.2.b.1.96 xs 4.1.2 rooted
then i took TA Backup.
now today i unlocked bootloader for the first tym (DRM keys preserverd in TA backup.)
now if i restore my TA backup while the bootloader unlocked, then will it restore drm keys and will bravia engine work?
m nt trying it because m afraid of bricking the phone.( just recovered from a soft brick yesterday). has anyone tried?
yes surely mate ...go ahead with restore....it will restore ur DRM keys and bravia engine will work as it was at the time of backup...
recommend to do this on stock firmware on which u had taken the TA backup....Hope this helps...

but dont it look weird, unlocked bootloader and drm keys working together? i didnt read anything like that on internet. can u quote any such link?
when u restore ur TA BACKUP it will restore ur DRM keys and bravia engine & ur BOOTLOADERS will get locked again....u have to unlock it again for custom kernel flashing...
so just flash stock firmware first on which u had taken TA backup and then restore it.... if you're using a custom kernel, you'll brick the phone.......so u must be on stock firmware first before restoration process...hope this helps...
Just to add since you just recovered from a soft brick.
If you restored your TA while using a custom kernel, you will hardbrick your phone which I believe is unrecoverable...

Hi All
When I bought my XM the fw version was .17.
Before unlock booltloader i was made a backup on TA partition.Then i was made ftf file with my stock firmware but yesterday i lost it
My Q is ,if i flash another firmware version .17 ,then can i restore the TA partition and relock BL again,or this can be make only for FW from who i'm bakced up TA partition?
I may be wrong, but you can relock your bootloader in any firmware, but if isn't the same version from when you did the backup then your phone will stuck in a bootloop after relocking, but if this happens, just use Sony Update Service to restore the correct firmware and get the phone working again after relocking...
Mhm only must be on stock kernel,thats right?No matter the fw version(.17 or .8)?

Hi guys... i need root mi ZL whit firmware 10.4.1.B.0.101 but not as... i need help
Sorry for my bad bad english :crying:
You have two options
1. unlock your bootloader and flash root(warranty, DRM keys lost)
2. downgrade to 4.2.2 firmware
backup TA partition then flash a 4.3 pre-rooted stock rom
lastly restore TA partition(must be stock kernel)
stock rooted phone with warranty and DRM keys
If you don't care about the warranty, I'll suggest just go with option 1, since option 2 might be time consuming.
Option 2 is always better. Who knows when your phone is going to break.

Not the OP, but am trying to figure out how to do this. All the root threads are a year old, so I want to make sure I have my facts straight before messing anything up. I have a C6506, US Generic but I don't want to lose my DRM keys or Warranty for resale reasons, so am trying to do this the "locked bootloader" way.
1) Downgrade to 4.2.2 firmware. Do I do this with Flashtool? This doesn't require unlocking the bootloader?
2) Root it .. Doomlord method? The Flashtool website says it can "root", too, but it offers no details on which method. What's the best way to go?
3) Install custom recovery. Which one? I see Nut's thread all talk about a dual recovery, but is that necessary? Can I install just one?
4) Is there a pre-rooted 101 for the C6506 US Generic? I can't seem to find one...
deleted (doesn't work with .101)

If you're on .67 or .101 firmware, just flash the .423 kernel via Flashtool.
Because it is a Sony stock kernel, you do not need to unlock the bootloader for this step.
When flashing is done, close Flashtool and reboot your phone.
Enable 'unknown sources' (found in security settings) and 'usb debugging' (found in developer options).
Now use Doomlord's method to root.
When rooting is done, it's time to install a recovery to your device.
If your're going to use a custom rom based on Sonys stock fw (like ExistenZ and RomAur), I strongly recommend using [NUT]'s dualrecovery.
AOSP roms (CyanogenMod, P.A.C., Omni, etc.) bring their own cwm recovery.
After root and recovery, turn off the phone and flash either .67 or .101 kernel, corresponding to your firmware.
Now it's time to backup the TA partition.

This is extremely helpful - thank you for providing links. I am wondering why this is so different from the method laid out here:
http://forum.xda-developers.com/showpost.php?p=51612704&postcount=12&nocache=1
Seems like your version is much easier, so I wonder why someone would go through all that trouble for the same result...
Also, won't I lose root once I flash the .101 kernel? Do I get it back using recovery?
Also also: the kernels linked above are for C6503 and C6502. Can I use the full FTF files for C6506 and just deselect flashing everything expect Kernel? It looks to be the same files, except that rpm.sin is included in the full files and not in the kernel FTFs.
when i flash a .423 kernel i got bootloops, am i doing something wrong?
after flashing back the .101 it boots normal
HI guys, i am interested into installing CM11 on my Xperia S , and i have backed up my TA and stored them on my PC.This procedure though, requires unlocked bootloader. In case i want to revert my phone back to locked( stock ) status, what do i have to do? I mean, how will i flash this TA backup? in a locked or an unlocked status? and via fastboot with Flashtool?

You save your TA via? Flashtool or some script? Use the same program as you use to backup. If ftool - probably flash it via ft.

Before i flash the restore file i have to be on stock Sony Fireware? And what must my bootlader status be like? Locked or unlocked?
Best idea its be on stock.
but why u ask about bootl? Now You have unlocked ;p So You must have unlocked? For restoring = re-lock it?
Hi everyone,
I have my TA partition backed up.
I've read somewhere here that if I restore TA partition it would also relock the bootloader.
Is that true?
I want to restore my TA partition, relock the bootloader, then flash a ftf (Customized USA 14.5.A.0.242 / R2D ) from XperiFirm. I would also be following this guide

Should I restore my TA, then relock bootloader, then flash ftf?
Or I can just restore TA (that would also relock the bootloader as a i was asking above), then flash ftf?
Also, I'm on XZDualRecovery, would I lose it (which I would actually want to do) when I restore my TA? or if I flash a ftf?
Basically what I'm looking on here is to restore my phone like it was just bough from a store but with the latest stock ftf.
Thanks

- relocking the bootloader does not restore your TA
- but restoring the TA partition relocks the bootloader
- by flashing a ftf you will loose your custom recovery
to restore a phone like you bought it just do the following steps:
1. restore the TA partition
2. flash a .ftf official from Sony with flashtool
3.reboot
and you are done
