Successfully recovered two hardware wallets in early September. One is the old version of the Library God, which cannot be powered on and has no recovery phrase or password. Data was successfully extracted from the chip, but unfortunately, the encrypted information regarding the coin address mentioned by the user was not found, possibly due to the main file being deleted, which caused it to not power on;

The other is a Trezor Model One hardware wallet, which has no recovery phrase and the high-level password was forgotten. After extracting data from the chip and running high-level password cracking with computing power, after two months of effort, it was finally successfully recovered.
