Hey!
I just wanted to know if it's possible to go back to the stock recovery in case I want to sell the phone completely stock. So is it possible?
Yes. If you're running stock fw with root, you should be able to do a repair fw via pc companion. If not, you can easily just flash your original ftf file via flashtool. Take a look in the general section of these z2 forums. All the info is there

I have been in the General section of the Z2 Forums, and I have read about how I can flash the FTF file to my phone, but I didn't know that the FTF includes the stock recovery Currently I have a Z2 with stock fw and a locked bootloader but with root. (Running stil on .314), and I'm planning to update to .167 with a rooted update package. (http://forum.xda-developers.com/xperia-z2/general/4-4-4-creating-rooted-update-package-t2933155)
OK, if you upgrade with that method to 167, I believe pc companion will still repair it back to factory settings (not sure whether it will be 314 or 167). If it doesn't, flashing an ftf will solve your problems.

i just wanted to get root on .62 so i decided to flash .42 with wotan server and root it, then update .62 withc pc companion, root didnt stay. Tried several times. Help?
update via OTA not PC Companion
just search from one of the threads.. you need to flash rootxperia.zip..then you will have root for your bb
1. Wrong thread.
2. Updating with PC companion implies you're downloading STOCK FIRMWARE. Stock firmware is NOT pre rooted and therefore, no root and stuff. If you want root, try rooting with the methods given here: http://forum.xda-developers.com/showthread.php?t=1409269
although, the most convenient and appropriate way to root would be to unlock BL and flash a custom kernel which is pre-rooted. Otherwise, whenever you flash a STOCK FIRMWARE, as the term implies, you well get STOCK stuff..and stock stuff is unrooted.
UNLESS, you flash a custom firmware which is modified and is rooted.

post in the right F***ING forum !!!
\Did you like check the F'ing general section ?? *FACEPALM*
Hello!
My phone can't seem to accept the OTA file, even after I've unrooted it. I don't have custom recovery and I have a locked bootloader.
The error message is "The file could not be verified" which I supposed was because of the root, apparently not.
Anyone know what's up? It's the standard C6833.
It`s because Rooting changes sone Files. Just back up your Data and use the Update Centre for reflashing
Alright I understand, I thought a unroot and removal of supersu would suffice.
Update center, that's the Sony PC companion yes? Won't I loose all my data?
Even with a backup, don't I have to set up the whole phone again? As if I would flash a ftf?

yes whith this method you loose the Data, but you can also try to flash an FTF, which should have the same effect. You just have to set some Files to the state bevore rooting or wait till you get the Update via PC Companion or update Service. I think the best way for you is to wait till PC Companion shows you the update.

The OTA may or may not work, if it fails then just flash an FTF (with or without data wipe depending on your mood) and then reroot etc
Need help
I am quite new to this and I want to root my z ultra. However I am wondering, whenever there is a software update, how can i install the update cos I know that after rooting I might be unable to update using pc companion anymore. Please can you throw more light on this. Thanks

what does the post of mine above yours say?
is there any way to return the Z2 Tablet SGP561 (Verizon edition) back to complete factory condition with PC Companion, FlashTool, XperiFirm, or other? the bootloader is still not unlockable on the VZW model as far as i am aware and i can't find any FTF for this model.
i am currently on 4.4.2 with root and NUT's dual recovery and have backed up my DRM keys. there are conflicting reports of being able to maintain root with the OTA to 4.4.4, so before trying I'd like to know how i could return to the current setup if it fails.
thanks

same here helep can i have to official stock rom for verizon xperia z2 tablet sgp 561. Sony pc companion says "need the Verison utility software update tool" need help pls thanks in advance
I unlocked the bootloader and rooted my Z Ultra (c6806) some time ago. I now want to return it to stock so that it can received regular updates from Sony. Unfortunately, I haven't done any rooting in a long while, and I want to make sure I don't brick the phone, etc. Is there a simple guide for bringing it back to a stock state where it can receive normal OTA (or PC Companion) updates? As of now, attempting to update returns this error message:
Problem: The phone/tablet contains modified software that cannot be updated.
Details: Sony Update Engine Failure (error 2003).

I apologize for what seems like such a silly question. Thanks for the help.
Have you locked your bootloader? If not then I'm afraid PC Companion won't do much for you. You have to either lock your bootloader and use PC Companion again or download FlashTool and a firmware you like, then flash it.

The bootloader is unlocked, and I have not relocked it. My questions are these. I looked around the site and I found these instructions:
Back to Stock:
To get back to pure stock Sony there are several things that need to be done:
1. Make sure you have root
2. Backup any data/photos/etc on the phone
3. Restore your TA backup with the TA backup tool above
If you are on a custom kernel or ROM you ZU will not boot at this stage
4. Start flashtool and load a FTF
5. Start the flash and wait for the onscreen instructions to connect the ZU
6. Connect your ZU in flashmode
With the ZU powered off
Connect to PC while holding the volume down key
Flash will start
7. Wait for flash to complete
My questions:
I did make a TA Backup, and I have it. If I don't restore the TA Backup (which seems like a little bit of a hassle), will I still be able to update through PC Companion?
If I just relock the boatloader, will I be able to use PC Companion to update from where it sits currently (I think 4.4.2)? Will relocking the bootloader on a rooted 4.4.2 device mess it up?
If I relock the bootloader, and I am able to use PC Companion to update, I will lose root, correct? And if I lose root, I will not be able to restore the TA backup, correct, unless I reroot it?
Here's my end goal. I just want the new stock Lollipop on it, and I want to be able to receive updates (they don't have to be OTA) from Sony. I gave the phone to my mom, and I want to keep it up to date. What is the easiest (and safest, least-likely-to-brick) way of accomplishing this?
Thank you for any help.
