[Q] Howto: Fresh and clean install of official 4.1.2
I own a Galaxy Note GT-N7000.
I never rooted it, just used two official updates provided by Samsung and then flashed the original 4.1.2 using Odin.
I have rooted my older Android phones (San Francisco) and used to try all kinds of ROM's on many Windows Mobile phones - I am not a exactly a noob, I just did not mess with my Note, because I am happy with it just like it is and because it is my work phone, which needs to be 100% working.
However, battery life is getting shorter (so I just ordered a new original Samsung battery) and, worse, the phone is getting more and more unresponsive.
This is the real problem: whenever I want to do something, it takes like 1-2 seconds, if not longer, before the phone reacts. This is very annoying. I don't have that many apps installed (I just stick with my preferred ones, instead of betting on sheer quantity). Still, the other day, the phone complained that there is no free space to install upgrades of some apps.
To make it short: how can I install a clean original 4.1.2 as if my phone was just purchased, i.e. with a clean flash?
Before you flame me and tell me I should spend the next month reading the forum: I already did!
I am afraid of the brick bug, so I guess that doing a wipe of the flash is not an option, as i guess that the bug has not been fixed by Samsung on 4.1.2. On the other hand, I do not want to root my phone, to install some custom kernel, to then wipe the flash and revert to the official ROM, risking to activate the counter, etc. Not that I don't know my way around flashing, soldering, building the flash dongle or even JTAG - I just don't have the time and nerve.
So my simple question: How do I securely wipe the flash and install a clean official 4.1.2 ROM on my phone, getting rind of 2 years of garbage files and God knows what else is slowing down my phone.
Many thanks for those guiding my way - I don't want to believe that there is a planned obsolescence in course, like Samsung building a timer that makes the phone get slower and slower...
