wifes samsung galaxy SIII mini GT 18190N is stuck in bootloop, ie samsung logo comes on the phone switches off and goes through the same process, I go googled this and came accross a few aswers, ie from a site called stack exchange;
Flash ROM + Gapps
wipe cache, data, dalvik cache
install Gapps (this is the part which I would always skip for later - BIG mistake as Gapps missing caused the boot loop)"
no idea what this means because unfortunately my phone expertise is very basic as is wife's, so we haven't updated or altered anything apart from normal updates, phone on payg as we don't use it often and is usually given to us when the kids get new phones, all help and advice appreciated
