My grandma uses a cheap 5.1-based Android phone, manufactured by a company named Manta (don't think it's available anywhere outside of Poland, just think your generic cheapest phone company), rooted with KingRoot and while it works really fine for the price, something peculiar happened yesterday.
She fired up an app informing you about air pollution on any given day (which she's opened tens of times already; I also use it and installed it myself so it's not like it's some malware - we're talking a regular, legit app here) and the phone just restarted. Thing is - it hasn't started since. It only boots up to the producer's logo and then nothing happens.
Nothing else was done with the phone. No new apps in the past days, no updates, nothing. Just regular internet and phone call usage + apps like the weather or the pollution one. I've tried restarting, taking out the battery before putting it back in, wiping cache through Recovery Mode... All to no avail. What else may I try (apart from a total wipe cause I wouldn't want grandma to lose all her data)?
