Basically, got this phone 11 months ago and now it's stuck in a boot loop (I think I know why this happened, since my SD card got corrupted and basically messed everything up, and I never got around to reset it to factory mode, I just took out the SD card and kept on living). However, funny thing about Wiko Rainbows, the boot loop is infinite. Even with recovery/factory mode, it just loops and crashes the first screen saying Wiko and when it finally reaches the second one, it just freezes there. So I can't fix the boot loop the traditional way. However, I saw many people talking about some "flash" tools or something, but I can't understand if that's for rooted phones or something, which mine isn't. Question is, what is the way to get rid of this and if it's this flash thingy how do I do it, or should I just give up and give it back to the store that'll probably do the same but take ages?
