Here I am showing How to claim warranty even after rooting:
If you are on Stock ROM and Stock Recovery: 1. If your have SuperSU installed then Go to SuperSu setting.
2. Now scroll down to CLEANUP section, there you will find a option to Full unroot.
3. Click on Full unroot, a warning will appear, click on continue, this will wipe the root access from your device.
4. After few seconds the app will auto close .
5. Now restart your device and uninstall SuperSU from your device.
If you Have Custom ROM or Recovery: 1. Reset Flash counter: (a.)First of all check Binary and flash counter value. To do this, Go to Download mode by pressing Volume Down+Menu+Power. Select continue. Confirm your phone's counter value there. Only IFF it is other than Zero, follow the next step
(b.)There is great tool from elite developer Chainfire known as Triangle Away.
(I suggest you buy this app from playstore to support the CF developer: https://play.google.com/store/apps/detai...away&hl=en
But If you can't then download from other than playstore.)
Steps to reset counter:
-Download Triangle away and install
-Open Triangle away from appl drawer, grant SU permission
-Depends on your recovery/kernel, it may ask to download add on about 7.4MB file, dwnload it.
-After downloading select reset counter from application menu
-Reboot your device and you will have counter '0'
2. Now after resetting your phones Counter, Download your Stock firmware(If using Samsung based phone then download from sammobile.com)
3. Flash your stock ROM using odin method (Comment here if you want to know more).
There you Go. Now you have Unrooted Android on Stock ROM. And you can claim your warranty.
