hello i have a xperia z3c 5803 and I want to restore it back to stock. i have backed up the drm keys (ta.img) from before, currently running custom rom slimlp and its an unlocked bootloader. What do i have to do first and how?
If you want to do a complete wipe and clean install it back to stock, use the Sony PC Companion software. There is an option to perform a clean reinstall somewhere. I know there is the option because I've done it but can't remember right now where it is.

Guys please suggest is there any way to have backup of stock ROM before rooting?
The only thing you have to backup are your apps and their data. I suggest to use "Titanium-Backup" it is not for free, but the best solution. I didn´t do a backup. Normally you don´t be forced to use it (until you want to install a custom rom)
Check some the threads in the Dev section about making your own ftf.

Doesn't having the original copy of stock ROM without the root and possible changes to flash counter give a clean ROM especially for warranty work?

There isn't any way to make a backup without a working recovery, so you need root, to delete all the trails of the root you need only to flash a stock firmware with flashtool.
(If you want to unlock your bootloader, take a backup of your TA partition to save the warranty)
You can find all on the forum
You don't need to make a backup of your apps and data, cause if you only root without unlocking bootloader it won't wipe anything.
Sorry, I didn't read the date of the post.
Ya got it and thanks for your reply. Anyways I have sold xz and moved on to Z Ultra.
Does it fit for Samsung devices, Tablets?

No, if they have a flash counter you can use the triangle away app from chainfire to reset the flash counter, and go back in warranty

Thanks Anyway, the problem redoing the Rom didn't change the Knox status. So since knox is trigger can't update, which I think is going too far. I should be entitled to updates and if they don't work that is on me. Looking for a forum where people may want to class action suit on Samsung over knox.

Morning all,
Am about to sell my Z1 and wanted to revert to stock so the buyer has what warranty is left, I have had two Z1 phones, both of which I have unlocked and both of which I have the TA back up's from, the problem is I no longer know which is which, is there a way to tell which one I need for this phone? dates on the folders won't work, but is there a distinguishing characteristic on there and would it be a problem if I flashed the wrong TA? OR would it just fail, no bricks?
Many thanks.
You would brick the phone if you flash wrong TA.

Yea that's what i'm afraid of crap. Anyway to deter which one is which??
I could maybe go by date but it's a risk, i've just reflashed an FTF file to revert the phone to stock, not 100% if this is the right way round or not, was I supposed to be rooted while restoring the TA partition?
Thanks by the way.
Yes, you need root to restore the ta.
Sent from my C6903 using XDA Premium 4 mobile app
None of the roms touch ta...u don't need to restore it...deselect that while restoring
@dladz
1. Root your phone
2. After root, try to use option Dry-run for restore TA, for each TA backup you made
3. If succesful, then it is the right TA for your phone
NB: you can also test all TA backup, to verify which phone have that backup, for make sure you didn't HARD BRICK your phone
4. Flash firmware via Flashtool, with full wipe, or you can do this after restore TA partition, and then flash firmware via Flashtool
5. And now, you ready to sell your phone
=)
I assume you do all this using Sony STOCK OFFICIAL firmware and STOCK OFFICIAL kernel
=)
Good luck, happy trying
=)

Thanks for this and to everyone else, unfortunately I've already sold it, so it's gone to it's new owner who's more than happy to be flashing rom's onto it and has no intention of sending it off for warranty purposes so it's win win, thanks for your responses.

I'm not really sure if you mean "flash" by "root" but yes. You can flash any stock ROM as long as your bootloader is locked. Your data will be wiped and you will no longer have root access.
It will be like a brand new phone. :silly:
Go check some guides on how to flash back to stock with flashtool.
Use Google for NSIS error fix. I think there are alot of guides aswell.

You need to use XperiaFirm software to download the official ROM and convert it into ftf.
Here are some Tutorials from @mrjraider
http://forum.xda-developers.com/crossdevice-dev/sony/tutorial-downloading-firmware-convert-t2837097
http://forum.xda-developers.com/showthread.php?t=2658952
Just read carefully and read the steps.
P.S. If you have unlocked your bootloader, you need to restore your DRM Keys, then lock it again.
Good Luck!
I am somewhat new to android...
Can someone please point me in the right direction here?
Currently I have an Xperia Z1 C6906 running rooted cm-11-20141112-SNAPSHOT-M12-honami with CWM.
I do not have a nandroid backup because I am stupid and did not know about this app.
I want to move back to the stock 4.4.4 Sony ROM and root. I cannot find this ROM or installation instructions.
Is this possible?
Any help would be greatly appreciated. Thank you.
EDIT: I have found XperiaFirm and downloaded a file through the software. I have a question though, I live in the US and I bought the phone second hand, it was originally set up on the network Claro. If i download the US Customized firmware through XperiaFirm and restore the firmware with FlashTool, are there any consequences?
Also, I'm not too familiar with how ROMS, Kernals, and Firmwares are all related. Can I just flash the firmware I downloaded onto the device and everything will be returned to normal?
you won't get no problems with different customizations, just make sure it is the right model number. did you backup your TA partition before? reply me in order to i get a notification. Thanks

I did not make a backup of my TA partition. Unfortunately, I didn't know to do that.
I have successfully flashed my phone using the software I mentioned above and everything is working as far as I can tell. Going back to stock, I think I have lost my root, unlocked bootloader, etc., correct?
Thanks for your help!

You lost your root etc on stock that is correct, but since you dont have your ta partition your camera performance will be lowered. İ suggest you to look at this thread for a fix. Good luck.

Hi there,
I asked this question before, but last time I got some confusing answers with regards to needing root.
The problem: My phone is slowing down and I want to wipe it completely (no system/app data left over) and restore it to factory defaults, preferably running 5.1.1.
What's the best/easiest way to do this? Will flashing the new firmware clear everything the way I want? I don't want to root, unlock the bootloader or lose the DRM keys, just a standard wipe.
On a firmware note, does anyone know where I can get Bell Canada 5.1.1 firmware?
Thanks a lot!
Foaric
Download FlashTool and there is XperiFirm to download the firmware you need
Just flash it, and you start from stock
I think just a standard factory reset should do this.

Great! So flashing will clear all the system/user data while leaving the DRM data intact? I'm looking to do it so that there's nothing left over to slow down the phone.
Thanks,
Foaric

The DRM are loosing only when you want to unlock your bootloader
But as mcgrathpatj said, try a factory reset in first
