Hey XDA-folks!
I will most likely be sending my Nexus 4 device in for replenishment/repair service.
I know that I lost the warranty by flashing my device & rooting it.
Is there a way to completely restore the phone to the factory state?
Do I just need to flash back to stock, unroot and lock bootloader? That would be it?
Thanks for your help! :highfive:

hey guys,
so i found out that my touch screen is all messed up so I plan on calling motorola tomorrow and sending the phone in for repair. but before I do that i want to revert the phone back to stock as much as possible so that i don't void my warranty. how do i?
(1) re-lock the boot loader?
(2) remove root?
(3) flash stock rom?
and actually another question is that is it even necessary for me to put the phone back to stock? would they really care?
thanks in advance.

some people have gotten away with sending in their modded phones, but if you want to restore to completely stock flash a 2.3.4 gingerbread .sbf file with rsdlite.
Hi,
Title says it all.
But basically, I'm selling this tablet to a friend, and he's worried about the fact that I rooted it once upon a time.
I have used WugFresh's toolkit to restore back to stock (4.2.2) and have also locked the bootloader (no unlock icon during boot splashscreen).
Is this enough to 'restore' warranty, or is there a root counter (akin to Samsung Galaxys phones) that Google can check?
Thanks for any replies in advance.

You would be fine w/ warranty.
My Galaxy S4 stopped working and I'm planning to send it back to get a replacement. However, I rooted my phone before this happened and I'm planning to un-root it before sending it back. I was planning on using the Triangle Away app as well to reset the flash counter but apparently I need to unlock the bootloader first. I read in this thread that you can flash a recovery and root the phone at the same time.
Would using that tool help me in unlocking the bootloader so that I can use the Triangle Away app to reset the counter and un-root my phone using Odin afterwards? The topic creator mentioned that TWRP will auto-lok anything you flash and works as a bootloader unlock but can anyone confirm this? I bricked my Galaxy S3 two weeks ago and don't want to face the same problems with this newly aquired Galaxy S4.
Is it worth it to go through all the trouble to just reset the flash counter or would un-rooting the phone be enough to send the phone back for a replacement?

Thanks, that guide looks really helpful. I do have one question though, it seems the Triangle Away app needs the boot loader unlocked in order to run successfully on the AT&T Galaxy S4 so what would be a good and simple way to unlock the bootloader and is there a way to check whether or not mine is unlocked? Would running the CASUAL tool take care of this (even if my device is already rooted)?
What guide/method did you use to root? Did you not use the bootloader exploit at that time?
I used the Motochopper tool located on this thread. I hadn't researched enough to know about the CASUAL tool at the time

Hmm...yeah I can see that method would probably work, but that wouldn't reset the flash counter to 0 would it? If the seller happens to notice that, then they won't send me a replacement and will probably tell me my warranty is void; hence why I'm trying to get the Triangle Away app to work but need the boot loader unlocked first in order to do that.

Well if all you did was ROOT the flash counter shouldn't be affected. Iused the same tool. I took the additional step of replacing Superuser with SU user. to rid myself of the "custom" unlocked symbolon boot up. However, the phone was NEVER really unlocked.
Thanks for the replies! I managed to un-root the phone by just flashing the AT&T stock firmware using Odin. Hopefully the binary counter won't be an issue.
I've rooted with King Root. Since I have got troubles with GPS and need to send phone for repair, I need to completely unroot with no trace that phone was rooted. Do you know hot to do it...? I've found that after unroot via King root RW is still mentioned while booting, so it's not clean unroot... Please explain if you can step by step.
Thank you very much.

Can you just do a factory reset from the recovery menu? Before I bought mine on Ebay I asked the seller about rooting and what if it bricks, he just said I can send it back within a month with no questions asked more or less.

Didn't try yet, in the meantime rather asking. Now did Nandroid backup and trying to find out if I can flash it without root in COS recovery or need to root again, install Nadroid backup and restore vie this app.
Also in Nandroid backup is missing script for Lenovo ZUk Z1 and no chance to find it, so I will cross fingers that it will not cause additional problem during recovering from backup...

Tried factory reset and full wipe and still not updatable, OTA update ends with same log "system was RW mounted" so it seems it's irreversible if you root. Very bad news, so you can't then apply warranty.
Do you have anybody advice how to reset into facotry default without any trace device was rooted..?????
You could try this toolkit, but you will need stock rom. http://forum.xda-developers.com/zuk-z1/development/win-zuk-z1-toolkit-0-1-alpha-t3235964
So it seems, it's not possible to make safe root and unroot on ZUk Z1 device as far as I know. Maybe somehow very difficult. That's not great news indeed. It's my first phone ever not possible root / unroot safely. And it's giving me feeling that Z1 despite it's great device in terms of hardware is not good choice. Also quite surprised how far away from well tuned OS is current release. I can't understand, why just CM didn't develop OS with possible root right or didn't incorporate full device backup. Honestly I don't care so much and probably neither other users about root, if natively in OS is complete backup / recovery. And... If I can do root without possibility go back (reclaiming warranty or not functional OTA update), then it makes me think, if really Z1 via CM is good choice or not. Despite really nice HW and materials... Pitty

No you should have read how to do it before you touched the phone. XDA is not a spoon feeding centre. It's for people who want to help themselves. If you had done the reading and had an issue with getting a part of the process to work, yes, but to blindly rush in and want it sorted out because of your own +++++ I must sound like a #### but you learn then act. Everyone has 4 posts and a screwed up phone wanting help. Errr there is a link between the two.
1.Flash a clean COS image via Twrp
2.Flash a clean COS recovery via twrp or adb sideload
3.Lock the bootloader
Hi,
My Rooted Phone with Pure Nexus has a Problem (see Picture) .My Cat dropped it :/
I am returning it to Google, so i want to go back to stock, stock firmware, removing the yellow triangle and so on.
I barely see anything, and Touchscreen is not working, but i can go to the bootloader.
Recovery is not acessible without Touch.
Can you help me? I know how to flash stock firmware, but does this remove the triangle? I also disabled the encryption...
Hope you can help.

Hi... You don't have any datas to pull off of your phone first? Once you flash the factory image, your datas will be wiped...
In case you want to go back to stock and assuming your bootloader is unlocked, simply follow this guide:
https://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928/
To remove the open padlock at phone startup, relock the bootloader ONLY WHEN YOU'RE DONE FLASHING STOCK.
Good luck...

You don't need to access recovery if you only want to flash stock image. Personally I would do it with flash-all.bat command rather than do all the parts individually. Since you already know how to flash the stock firmware you just need to lock the bootloader after and you are good to go. Supposedly unlocking the bootloader doesn't void the warranty on the 6P but it couldn't hurt if you are sending the phone back to Google.
Thanks !
I was assuming the data is lost anyway, the good thing is i pictures are sent anyway automatically to dropbox, many things are in the cloud.
Okay, the bootloader thing was unclear, cool, thanks, ill flash it
Thanks!
