I was out of range of wifi coverage for a few days. Suddenly, one day my iPad started showing a message that iCloud storage was almost full (though about 3.6 GB was remaining). Today, it suddenly slip into recovery mode and shows the iTunes icon with the picture of a lightning charger and an arrow. iTunes on my PC, now forces me to restore my iPhone and thats going to erase all my data, which I don't want. I have performed a reset, reboot. Can anyone please suggest how to get myself out of this problem? Thank you.
