I even took photos of the seed phrase and I have followed what ledger told me today to reset the device.
What do you mean you took photos of the seed phrase?!
You should NEVER do that and you should NEVER keep seed phrase in any digital form on your computer, either in image or in text form.
This is big security flaw and you should not consider your coins are safe like that.
Seed words should only be kept offline on paper or metal plates.
I have spoken to a crypto recovery company and the guy told me that there is a known issue with ledgers where they allow you to transfer all coins and tokens apart from bitcoin after you update some software variants. he said it isnt widespread but they have seen several issues like mine.
Crypto recovery company sounds a lot like a scam that sends you private messages first on social media offering their ''help''.
Don't listen advices from anyone and don't send seed words to any website, especially if they say they are ''leDgEr SupPorT''
Lets say ledger dont assist me, is it likely that the bitcoin is lost forever ?
Bitcoin is not lost forever if you can see it on blockchain address and if you didn't compromised or exposed your seed words.
I have to say that I am starting to doubt if any of this you are saying ever really happened, so can you please show us some proof of your conversation with Ledger support (you can blur private sections)?
Thank you in advance.
