Ledger hardware wallet developers stated that an unforeseen problem was found in software version 1.5.5 for the Nano S model. Improvements in the security context have affected the amount of device memory.
When planning for this update we didn’t anticipate the impact it would have on Ledger Nano S capacity. This was not planned obsolescence, simply put, we messed up. We apologize and we’re committed to making it right.
The project team apologized for the incident and promised to fix the problem during the second quarter of 2019.
The project also announced the addition of Nano S support in the Ledger Live mobile app on Android.
Earlier, researchers at Wallet.fail discovered a number of vulnerabilities in the Trezor and Ledger hardware cryptocurrency wallets. As a result, they were able to conduct a series of successful attacks on wallets during the Chaos Communication Congress in Leipzig.
