backup apks using ES explorer to SD card (by copying backups folder).
backup contacts to email account (as well as a local vcf file)
backup entire Whatsapp folder (while restoring, Install apk, copy the old folder back and tehn set up whatsapp)
there are apps to backup texts as well.
Remove SD card.
Reset + Download OTA and install (automatically)
Install apks and restore contacts..
No need to root as well
