Further explanation, clarification.. and a small question and open discussion.
Since no one replied to my question i did more reading and youtube videos etc and gained a bit of knowledge from dr.ketan too and thought to share my knowledge and PLS DO CORRECT ME IF I AM WRONG
. And feel free to add more comments.
There is sudden death syndrome in s3, note 2. All exynos samsung processors on 4.1.1 are affected. The phone suddenly dies without any reason. Not only that there is serious security hole where any app can gain user information. These both fixes are supposedly fixed in 4.1.2.
But chainfire came out with a great apk app which you can install as a normal app on phone which roots, unroots phone in one click and not only that it plugs the hole which was letting malicious apps in. But exynoseabuse doesnt take care of SDS (sudden death syndrome) and it only works on 4.1.1 and doesnt work on firmwares LL7 after jan 2013
There is option of pluging the hole without rooting the phone but if you patch exploit (plug the hole) without rooting you cannot use this particular app to root your phone - you have to use other methods of rooting like cf auto root etc
On the other hand, If you decide to root your phone you can disable exploit (plug the hole) just by one click or you have the option of disabling the exploit every time you reboot the phone. so the app will patch the hole before any other normal android app runs.
Then if you decide to ever unroot the phone or send it away for warranty just click unroot device..
This is here where i am bit confused IF we unroot the phone the patch remains there.? is there a way to remove the patch as well while unrooting so that there are no traces of patching or rooting etc and can use this app patch again.?
Also if we dont flash cwm, we can flash custom firmwares using mobile odin right and if we are sending it for warranty just flash a stock firmware in odin and it will be all good.? NO triangle or flash counter reset etc..?
