For those asking the reason why your account was deleted, I think it's because of Privacy settings in LINE. There's an option that asks you to authorize carrying over an account and transfer it to another phone. If you authorize this LINE will give you 24hrs to transfer your account. If you don't authorize that settings you won't be able to use your account in another device. This was implemented by LINE like 1 year ago and it has been changing throughout the updates.
