[Q] How to roll rooted Z back to original state? (TRICKY)

Hi,
my Xperia Z got damaged and I need to ship it back for service repair. But I already rooted it so I can't apply my guarantee atm. So my question is how to roll it back to the original state that nobody can find out? The problem I am having is that half of my display got cracked (itself - seriously!) and is not responding to any touches (just right half). So after I turn on my phone I am obviously stucked on my own maze lock unable to unlock it. Also I am not able to log in via my google account to prevent the maze lock (can type but the crack is near the button Send so I am not able to send my credentials). Rotating the display doesn't help either. Luckily, I installed CWM recovery which uses only hardware buttons so I should be able to use WIPE DATA/FACTORY RESET option which will wipe the maze lock so I should be able to connect it via Sony Companion. But then I am not sure if I would be able to roll it back to the original state after. I don't know what would WIPE DATA/FACTORY RESET do to root and CWM. Is Sony Companion able to repair/restore my phone to the very original state? Would CWM still be installed on the phone? Would I have a root?
Here is a list of things I did with my Xperia so far after rooting:
- Uninstalled Sony Movies app by Titanium Backup (I didn't backup my phone before - stupid).
- Upgraded to SuperSU Pro (don't think it matters)
- Installed CWM
- Flashed [SOUNDMOD]PureXAudio (I am still able to revert this via CWM and and the stock audio flash)
So I am looking for a best way to restore my phone to the original state before I will send it to the service. My phone is from Japan if it matters to kernel or firmware. If you would suggest me to use some kernel/firmware could you provide me a link please?
Thanks in advance!!!

Not tricky at all
Rooting does not invalidate your warranty. But if you are outside of Japan, and your phone is japanese, you won't be covered by warranty anyway.
If you still wanna get the phone back to original, just flash with Sony Update Service. If SUS detects modified software and refuses to flash, which it probably will, you always could flash with flashtool.
Flashing will bypass the pattern unlock and rewrite everything back to stock.
If there is important info you might wanna save before flashing, connect a mouse to the Xperia Z and use it to unlock the pattern.

Why? My phone was ordered from Japan, came from Hong Kong, was delivered to UK by my gf and will go back the same way...

OK, I thought you were taking your phone to a local Sony Service. Warranty is only valid on the country the phone was bought.

USB OTG cable comes in handy.

If warranty is denied, claiming user neglect, then root doesn't matter - you will have to pay. If they believe screen cracked by itself and honor warranty, then root also doesn't matter as rooting won't crack the screen

just flash the orginal firmware via flashtool
rooting your phone does not void your warranty .. unlocking the bootloader do

[Q] Factory reset without knowing pin?

So basically someone (I don't know who, I was drunk, I thought it was a joke but no one has come forward) has set a pin on my phone and I can no longer use the thing.
I just want to be able to make phone calls again.
Is there anyway to factory reset my Sony Xperia Z1f without knowing the pin? What are my options basically?
Thanks,
Alex.

Go to Sony Service or the Store where you bought it, they will reset your phone a think for free.

I was hoping to be able to use it this weekend *sigh*
Do I need the receipt/box or something? I bought it from a small importing company who have told me I will need to mail the thing to Sony at my own expense as the nearest service center is a 10 hour drive.
So there is literally no way for me to unlock my phone short of how ever many weeks it takes Sony to mail it back to me?

It's like the shop where I bought mine, they said I got Manufacturer Warranty so I will have to send the phone to Sony, but actually when I call them they will do this for me. Go there and ask them or call them.

Factory Reset the device with PC Companion.
It doesn't ask for a PIN when I just tried now.. I needed to FR mine for the 4.3 update, so I tested it for you

Sorry what is PC Companion? Can you please post a little more info, would be super grateful. I have not been active on these forums in quite some time and am out of the loop haha

Also, I tried following this guide...
http://unlockbootloader.sonymobile.com/instructions
But I can't access the service menu on my phone from the emergency dialer like many YouTube videos show.
Why might this be?

Pc companion is a program for your Pc where u connect your phone and you can do loads of things like reset update etc...is made by Sony so just do a lil Google search and download it... Or go on Sony website

This have nothing to do with your problem, it's for Unlocking Bootlader not the phone. If you do this, you will lose your warranty.
Go via PC Companion.

Ok I got PC Companion and figured it out and have updated my phones software to the latest version.
But now after reading through these forums I think I would like to flash a custom ROM, however looking in the service menu my phone says that bootloader unlock is not allowed.
Is there someway to still unlock my bootloader and flash a custom rom?

No, if Unlock Bootloader Allowed say NO you can't unlock it, but you can flash custom roms with stock kernels and also root your phone. Unlock Bootlader is needed to flash custom kernels only.

[Q] Purchased Used Nexus 6. Not locked out

I recently purchased a nexus 6 off ebay, likely a mistake, and now that I try to run the setup i can't because i'm not the original account on the phone. Is there anything I can do to get past this step, remove the old user account and add myself to the phone? I know the security measure was put in for a reason, but it definitely makes it hard when someone like me gets the phone and is now stuck with a good looking paperweight. I have tried contacting the seller and getting them to provide me with their info for the purposes of setting it up but they are reluctant to offer that up. Unsurprisingly.
Any help would be appreciated.
Thank you,
Fk

I'm sorry but the only way is with that password. This is fault of the seller, they did a factory reset without removing their Google account. If the seller won't help you, contact eBay resolution center.

@fkoulbot,
Unfortunately, plenty of threads here with the same situation.
What @Evolution_Freak said, or open a PayPal claim. Device "Significantly Not As Described". You'll get your money back.

Or, just post it back to him at his expense, and get him to do it properly.
"Hi,
I understand that you feel uncomfortable giving me your Google password. Since the phone is unusable without it, I will have to consider opening a paypal dispute.
To avoid this however, if you offered to cover the cost of 2 way postage of the device (+insurance), I could send the device to you to log into and remove your account properly before resetting and returning to me."

Hey, buddy. I had the same thing happen to me on Swappa. Fortunately the guy was willing to give me his password... BUT in the 2 hours it took him to respond to my dilemma, I had already found a way around it. (Take note that my bootloader was already unlocked when I received the device.) Here's what I did.....
I tried flashing a couple different ROMs to no avail.
Then I realized it was because I was flashing 5.1 ROMs.
So, I found a 5.0.1 ROM that doesn't have the reactivation built in, flashed it, got it set up, then flashed a new 5.1 ROM. It worked for me but YMMV. I do believe having an unlocked bootloader in the first place helped. Hope that helps.

Thanks so much for that info. I had actually received and tried that but because it wasn't unlocked i was stuck. I did get the login info but now worried that they somehow have access to the phone. I noticed the label of a "group" of apps on my home screen was randomly changed. I did DL an antivirus app and it found something but I'm still worried about the security of the phone. Do you happen to have any suggestion on the best thing i can do to absolutely clear any of the old account information etc?

First thing I would do is go into Settings -> Accounts and remove the Google account that it was originally linked on. Then add your own. Do a factory reset, and you should be fine. If you want to go the extra mile, set up the reactivation lock under your account. I do believe that should clear any permissions he may still have as they would be linked to his Google account.

Boot to bootloader.
Fastboot format userdata
(Note that this will wipe everything, including contents of SDcard.

I would lock then unlock bootloader which would wipe the phone and then go to google and download latest builds and flash the phone to factory stock. Boot in, if there isn't anything funky, then I would made a backup of the stock and flash custom ROMs from that point. I like to check first if it works bone stock wiped before tinkering. That way if anything is still wrong with it I know who's at fault.

Why would you lock the bootloader? If you want everything wiped do > fastboot format userdata

Well, more likely if it's locked I would just unlock, but yes the act of flashing it to factory images will wipe in one go. Relocking and unlocking is redundant.

Guys does anyone confirm that is any way you can remove the Google Account Lock on Nexus 6 that the previous seller didn't remove the Goggle Account?
Thanks in advance!

Im having the same dang issue!! Hopefully I can get it flashed since sell won't give me password.

How to keep OP3 protected from any kind of theif flashing the device

I had kept my bootloader unlocked for flashing new ROMs but unfortunately i lost it on train and now i can understand that the theif can easily flash a new rom and so i can never retrive my device as far as i understood that i have to keep my bootloader locked but this means that i have to unlock and relock my bootloader each time i want to flash a new rom so this is very problematic for losing internal data too every time.
Also i don't have a job else i would have brought a new OP3T. I hope that in future OP can introduce some hardwire based tracking for lost devices , what do you people suggest?

I suggest that if the thief is able to flash a new ROM, he will be perfectly able to open the bootloader. So I recommend that you do not worry about having the bootloader open.
As for the tracking system, I think Google has already developed certain functions aimed at this use. When I have time I will investigate about this topic and update this post.
Please, be awere.

Try Google device manager. Thats the tracking tool you searching for. ?

not a big deal to reset FRP. Samsung and LG FRP takes only few minutes to be removed with z3x box. i think even stock rom have some bugs to bypass FRP. Best way is not to loose your phone.

It won't help you now, but take a screenshot of your imei, then back it up to your photos. If your phone is lost or stolen report it and depending on what country you live in, it will be black listed. Then it won't work on any carrier, no matter which rom is flashed.

Since I had kept my bootloader unlocked I believe that can easily flash a new rom so Android device manager won't be useful at all

Ya I know that I have already submitted FIR in police with the IMEI number but I believe these days they remove all the parts and sell the parts differently so very less chance in recovery

Buying possibly locked phone running Android 5 or 6

When buying from ebay dead phone it might be either password, fingerprint or even Google locked (not sure what the last one means).
Would I be able to use it after fixing the screen and hard reset?
Older Androids at least up to 4.4.2 upon the hard reset simply eraze all data and let you use the phone.
What is the situation with Android 5, 6 and 7?

Be careful if the reactivation lock is on from settings you won't be able to use or flash anything no matter if it's on android 4,5, or 6.
Even if you do hard reset when setup the device it will ask for samsung account password.
You must have device owner password to unlock the reactivation lock.

Thanks!

Yes FRP does not seem to be an easy one, so all ebay phones are potentially bricks. BTW FRP was first introduced in 5.1
