I like to share with you guys this experience as it chose me a lot of unnecessary stress.
if you have the same problem as I had => if you have an old Ledger Nano s where you lost your 24 words recovery seed from and on top of it he's stuck on a very old firmware (1.2.1) then there is a solution.
After hours digging through information provided by Ledger themselves and other forums, where people describe their ledgers Flashing themselves, out of the blue breaking, wiping because of wrong passwords, and almost always resetting when updating the firmware, I was getting a little bit sweaty of the idea but the funds will be lost forever.
When you have a old Ledger like that the firmware is not compatible any browser wallets nor does Ledger life even recognizes/ see your Ledger...
Apparently there was a recall in place by Ledger where you can since you're old outdated Ledger and get a new one,... This of course wouldn't help in my situation.
After a wile trying desperately different wallets and approaches to get to the funds ( in my case these were ERC20) I found that mycrypto has a desktop wallet where if you connect your Ledger and then turn off 'browser support' in your ledger settings you can still reach your Etherium Wallet.
This was of course a massive relief,
conclusion :I'm more fan of Trezor
Thank you for this information you shared to us. Though I don't have ledger nano Yet. It's an awareness for me. Thank you and do more informative articles like this 😘
