How to restore back to warranty acceptable version of the phone? - Xperia Z3 Compact Q&A, Help & Troubleshooting

Hi, so I broke my screen and I went to repair it but they find out that I have non-original-hacked-version of software/ROM and said they can't help me like this and the only way they'll fix my screen is if they also replace my board (idk why..) and thats gonna cost about 80% of the phone's price..
So anyway, I need to clean up my phone before I send it back to them..
What exactly do I need to do so it will pass the warranty test?
I mean while have rooted/ exposed version of 5.1 and I'm pretty sure its non-stock ROM - I think its the Slim ROM (the phone is still in their labs so I can't check)..
I am not sure what do they check so if some one could clear that up for me I would really appreciate it.. and a tiny guide for how to do so would be a bonus (but not must I can google it ofc..)
Thanks alot ahead!

1. Restore your phone to a stock firmware using FlashTool
2. If your phone has a unlocked bootloader you will need to re-lock it and restore your TA-Keys (if you made a backup)
That should be all, that's all I did and they restored my phone, replacing the motherboard.

Thanks alot

[Q] Unrooting & pulldown menu from lock screen questions?

Hi guys, just 2 things to ask:
1) I rooted my phone a few weeks back & thought everything was ok (I used binary's v26 toolkit) & thought everything went ok, however only noticed there were problems when it came to deleting/renaming/modifying anything in /system where my phone would constantly reboot.
So I have been advised to use SEUS to restore stock & to fully unroot - I just wanted to make sure this is safe to do & I won't have any errors etc? I know I will have to backup everything which isn't a problem, but is it fine to use on a 'broken' root? What is the difference between using SEUS to go back to factory & using the phone's factory reset anyway?
I plan to use this short guide: http://www.youtube.com/watch?v=B8LlNufSP2E, can anyone confirm I can use this method in my current situation? I also have CWM, I don't plan to re root after etc, not for a while anyway, so doesn't bother me losing CWM & root!
2) I have only just noticed when I pull down the status bar from the lock screen, only the back & home shortcuts appear, whereas the 'recent apps' shortcut doesnt? Is this normal? I could have sworn it used to be there, makes sense that it's not but just wondered! Probably never noticed it was absent to begin with
Appreciate any help & advice.
Many thanks!

SEUS will completely wipe your phone same as a FTF with data, If you unroot it there will still be the old folders just inactive so for warranty i would just say flash with a FTF but if unsure then just do a SEUS restore

I wouldn't have a clue how to use FTF, I am pretty much a noob to all this
But using SEUS to restore will basically get rid of root, just the old files would be there you mean? No way to get rid of them? My main purpose to unroot is because I hear that if I update to 4.2.2 (whenever it arrives!) there is a good chance I will get bootloops & other issues as my root is not 100% fully working. So I don't want to risk it when it comes to updating really.. I am pretty lost with what is the best method to do to get rid of root
SEUS will make my phone go back to how it came out of the box, just to confirm? Sorry for the many questions, am just very cautious!
Thanks for the reply too btw
Yes sues will resort it to out of the box, room gone, folders, pictures etc.
Just one little pointer look into flash tool beta 5 in xz original android and then download a global ftf in android development there is a tutorial about using it on here somewhere, it is always best to keep it to hand just incase something happens while you are nodding then you can easily go back to stock, I think 4.2.2 will be fine upgrading to because it will just delete root
Just found one

Lol I am getting a bit confused because everything seems to be getting a lil complicated for my understanding
Is it necessary to have global FTF even after I successfully use SEUS to restore back to stock? Like I said I don't plan to re root after this, it has given me a headache for a few weeks trying to figure out what to do haha, I don't want to risk bricking my phone which is prob what will happen knowing me!
I know updating to 4.2.2 will remove root & update fine - BUT would that be the case with a 'broken' root like mine, since mine is not working properly? Otherwise if it's fine to I may as well just leave the phone as it is & update when it's released, that way I won't lose any data etc & have root removed too If however there will be problems which another user has mentoned such as bootloops because of installing root incorrectly, I want to just use SEUS to restore my phone & remove root that way just to be sure. I just wanted to know if that method in the youtube video will be ok to do on mine, because I have said before, my root is 'broken' lol.
Hope that makes sense?

Going back to stock help

I'm hoping someone / you guys can help me.
Ever since I did the 4.4.2 update, my phone has been brutally slow and killing the battery and overall just a POS. I looked for wakelocks, screen is extremely low etc. I'm just sick of it to be frank. So I'm hoping to wipe everything, format the sd card and completely fresh as if it were a brand new phone.
From spending the last 3 hours researching, I can't seem to find what I'm looking for. ( maybe I'm overlooking it with my lack of sleep since we have a 8 week old )
From my understanding, I can't downgrade to an older firmware cause of knox. ( I would love to do this, so then I can root it and put on knoxraid or some other rom so I don't have all this bloatware etc )
Now with that being said, since I can't downgrade, I also can't replace my phone since I can't find the 4.4.2 files to odin my phone. I can find the mj5 files, but not the NC2 ( I think those are it )
Can someone please help me here, my sanity is running thin ( again, lack of sleep )
Thank you in advance.

there are no oden files for 4.4.2 you have a couple of things you can try go to settings,general and backup and reset and do a factory reset or go to best buy or a att service center and have them reflash the 4.4.2 firmware

So to confirm, Best Buy or AT&T can flash it? I pretty much can just go in there and say " Hey can you reflash my phone?"

From what I have heard the employees in the samsung experience shop inside of bestbuy have a tool that can reflash the phone. Make sure to call ahead before you go into the store. Explain to them whats going on and ask them if they are able to reflash the stock version on the phone.
If your phone says that its rooted they are not allowed to do the flash.
If they do not have the software my recommendation would be to contact ATT. Since it is a software issue the phone will be covered without that warranty that you pay monthly for. So they will ship you out a refurbished (like new) phone and then you will send yours to them.
EDIT :
And also the ATT service centers do not have the tool to reflash your phone. Only Samsung has access to that. ATT service center will just give you a number to call to have them ship you out a phone.
Thank you Aaron, I appreciate it

I've been to Samsung smart station at Best Buy:
1. Being on MLG 442 it said that being up to date it couldn't flash
2. The rep "said" that since it was previously rooted it wouldn't allow the flash anyway
Sent from my SAMSUNG-SM-N900A using XDA Premium 4 mobile app
there is adb sideload of the ATT OTA update
device must have NB4 or NC2 otherwise update aborted due to expected fingerprint not seen by the OTA such as MLG or MJ5 MI9 MI1
if rooted or not will not matter it's the fingerprint = NB4 or NC2 to get stock 442 OTA

not certain what i can link ya to..but

there are probably more appropriate versions on the forums to install adb to windows seen even one with a GUI being worked on
some youtube videos searched showed setting in DEV mode to turn on usb debugging & change security settings
booted the phone to recovery select adb & plugged in the usb
run adb.exe from a command prompt on windows
got the OTA from thread

I was having problems also... Just do a factory reset and then do a wipe in recovery mode and you'll be good to go. I got a brand new phone from AT&T service center, came on MJ5 - I installed some apps and setup the phone before I could get on wifi, updated to kitkat when I got home and I had issues all over again. A simple reset works.

[Q] Do I HAVE to unroot my phone when giving it back to Sprint??

Hello guys. I switched to AT&T today because I am seriously out of Sprint coverage nowadays. I am expecting to get a bill for my m8 since I left before I had paid off my phone. When sending back my phone, is it neccessary to unroot, flash stock recovery, relock, etc?
I changed my CID number in order to remove the tampered signal, I think. So I have no idea which stock nandroid backup to download here. Also, half the links for unrooting instructions here are dead, most importantly the file needed for flashing to unroot. So basically, this is just a headache and I dont want to deal with it.
I sent sprint a rooted HTC EVO 4G back when I had broken the screen and they sent me another for insurance purposes. They never said anything.
So what should I do? Aren't they just going to put a new shell on it and make it look new and sell it to someone?

I guess that would depend on who receives it at the return center. Chances are that if they plan on resale they will wipe everything and run an RUU or the complete reset version of it if there is one (which most of us wish there was and we could get our hands on)
If that is the case you can always run the latest RUU on your own before sending it in.

[Q] RUU

Hi, I did a lot of things with my One Mini 2 and I actually really don't know what to do anymore... So much options and yet there always seems to be a problem. Let me explain everything.
What I did:
-flashed a custom rom, then went back to a stock rom of this forum
-flashed the dt2w kernel, it messed up my phone so I then flashed the liberty one, which worked
But with the liberty one I had some memory problems, for exemple I couldn't take screenshots... That's why I decided that I wanted to put my phone just as it was when I bought it, I really hope that's possible, by that I mean having official firmwares etc, therefore being able to do official upgrades from my phone (is that what OTA is?).
I looked on internet and it looks like what I need is RUU, as it includes everything (from what I understood)... I know a lot of threads were made about this, but quite a few months ago, so that's why I'm making a new one, and to make things clear.
Also, I downloaded an official kernel from htcdev.com, but each time I tried flashing it with TWRP, it "failed".
So, if you guys have an answer, solution or, in best case, the actual RUU, that would be great.
Thanx

Still no RUU's avaiable as HTC wont release them. your best option is to use TWRP backup and restore.
Original stock backup
Thank you, but my backup kind of disappeared... I saw your post where there was the "HTC Original Backup.zip", I tried to flash but again it failed... Am I supposed to flash it as a backup?

You need to send it as it is to your phone and use TWRP > restore. choose file and done.
Thanx so much for answering... I uses the backup you told me to. Although I had to use the "install" option instead of the backup one, it now works perfectly! But how do I know if my phone is "official"? Are the upgrades going to be made straight from the phone?

Yes OTA updates should work just fine. just look for updates in settings>about >software update.
you may have one for polaris office.
Hi, I just want to check this too before I screw up wife's phone..
She has CM12 on her phone now as I replaced recovery as well as unlocking bootloader. Now she wants it back to stock as too many things crash on her. I get that I can install your backup but what worries me is that other posts have said you need the stock recovery to allow for OTA updates to work and the link to this no longer works.
She MUST have OTA updates or my balls will be removed, so can you please confirm this, but also explain why.
Thanks (on behalf of my testicles and unborn children!)
(Oh, and she wants it unrooted ant the bootloader relocked)

HTC One M7 Black screen problem

Hey; i was hoping you guys can help me solve this issue.

hope you guys can fix it.
Btw, i try to do factory reset and its do wont work either.
Are you rooted? or maybe are you familiar with the process of unlocking bootloader, flashing recovery and installing custom or official roms?

Im not sure if im rooted, how can i be sure?
about the other things im not familiar with them so much.
It looks like something went wrong with your update and your system partition messed up. The ssolution I would suggest you is to
1) Unlock your bootloader
2) Flash custom recovery (twrp or cwm)
3) Push a new rom (official or custom) to your phone's storage using custom recovery
4) Install new rom using custom recovery
This will probably void your warranty so if the phone still has a warranty and you dont feel confident doing any of these, it would be a better idea to bring your phone to an official service.
Now if your warranty is expired and you would prefer giving your money for a new phone instead of service, then you have nothing to lose and try the steps I suggest you.
There are plenty of guides in this forum for each of the steps I mentioned. Remember, if you dont feel confident doing any of these, try doing them only if you have nothing to lose because there is a chance that the phone is bricked (your phone seems to be soft bricked currently).
