As the title stated. There is no "system upgrade or similar in the Settings app but There's a newer ROM than my current one. So, I plan to upgrade it through SP Flash. My phone is Lenovo A606 (MT6582) and rooted with TWRP. Do I need to UnRoot it first and flash using SP Flash or just flash with SP Flash? Another thing is I dont wanted to clear my data, is it possible to update without wiping all my data?
