Noob question
Given that my phone was dying (unbelievably slow), I've decided to install Franco kernel.
To do that, I've installed a custom recovery (and rooted the device).
Today I received a notice of an OTA.
I tried to install it and it failed.
I reverted to stock recovery.
I downloaded the latest Shamu image, erased system and pushed the latest system.img.
I rebooted the device in order to start updating the phone, via OTA.
Upon rebooting, I was expecting to have lost custom kernel and root, and it was not the case.
Also, upon checking for updates, the system told me I am updated to the latest patch.
Can someone please clarify to me why root and kernel have not been altered, and if the update came via system.img.
Also, how do other users go about updating their rooted phones, using this thread first post?
Thank you.
