[Please help] Upgrade Rom without "System Upgrade" in Settings
(16-11-2015, 04:18 PM)a4apple 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?

No need to unroot. You best use the firmware upgrade option in sp flash tool but that'll wipe data

You could untick userdata when flashing the upgrade
(17-11-2015, 11:06 AM)a4apple So unticking the userdata will upgrade the phone without wiping data and without any issues with root? Will try it later.

In theory Yes, but here's the shocker; you might need to do a factory reset if you encounter a bootloop or phone stuck at boot animation
(18-11-2015, 11:33 PM)a4apple Is it okay if I didnt flash preloader also? I flash everything except for preloader and userdata (to keep my data), is it okay? Will my phone boot without problem and any error?
(19-11-2015, 12:42 PM)hovatekWhat re-partitioning? Is there an option in SP Flash? Which do you recommend me to do? Flash everything (download) or without userdata or without userdata + preloader or firmware upgrade (including everything)(18-11-2015, 11:33 PM)a4apple Is it okay if I didnt flash preloader also?

i cant guaranty you this. I strongly advise you go with the firmware upgrade option for re-partitioning sake
