Veryfing whether device is jailbroken or not
Greetings, everyone. I recently bought an old second hand 10th generation Paperwhite Kindle and I wanted to verify whether it is already jail broken or not. It has firmware version 5.16 and it is in Airplane mode already.
How may I check whether it is already jailbroken or not?
In case it was, would applying a newer, modern jailbreak be advisable? Or do I risk a brick?
