# iCopy-X v1.1.4 Released > Firmware v1.1.4 is the third community release since v1.1.1 for the open-source iCopy-X. Together the three add Hitag2 cloning with Paxton-to-Hitag2 writes, a rebuilt MIFARE Classic key-recovery pipeline that saves recovered keys, SEOS downgrade through the ICS Decoder, a French UI, macOS fixes and two new plugins. _2026-09-05_ Firmware **v1.1.4** is out for the open-source [iCopy-X](https://github.com/lab-401/icopy-x). It is the third release since v1.1.1. Together the three add Hitag2 cloning and support for the ICS Decoder, and rebuild MIFARE Classic key recovery. Most of the work is from [amec0e](https://github.com/amec0e), whose Paxton, Hitag2 and MIFARE Classic changes span all three releases. [Dysonian-Lab](https://github.com/Dysonian-Lab) has added ICS Decoder support. Grab it from the [v1.1.4 release page](https://github.com/lab-401/icopy-x/releases/tag/v1.1.4). ## Notable changes ### LF (Low Frequency) - Added Hitag2 read and write, so Hitag2 tags can be cloned to Hitag2 blanks (scan was already supported). - Added Paxton-to-Hitag2 writing: it uses the default Hitag2 password, writes block 1 last and reads back with the Paxton password to confirm. - Changed Paxton dumps to store blocks 1 to 7 rather than 4 to 7, so a dump can also be written to a generic Hitag2. Older dumps still work for Paxton-to-Paxton. Tags to be written to a generic Hitag2 need a new dump. - Changed the Paxton dump filename scheme to `Paxton-ID___N.txt`, with a fallback for older dumps. ### HF (High Frequency) - Added a full nested attack pass, run when less than half of a card's keys are found. - Changed key recovery to seed the nested attack with the user dictionary, the built-in defaults and 61 hard-coded keys instead of the full Iceman dictionary. - Changed key recovery to run `fchk` again after the nested attack finds a key. - Added `saveLearnedKeys`: any recovered key not already in the dictionaries is appended to `/keys/mf1/mfc_users_keys.dic`. - Changed erase to use the same key-recovery pipeline as the read flow. - Changed Darkside recovery to run only when `fchk` finds no keys. - Fixed UID verification failures when writing Gen1a and Gen2 cards. - Fixed Gen1a SAK and ATQA normalisation when a dump reports a SAK of `0x88`. - Fixed ACL decoding for JSON dumps. - Fixed sector-trailer key B not being written. - Fixed 4K nested recovery selecting the wrong sectors. - Added the missing Salto and NSP global keys and the University of Portsmouth library-card keys. ### ICS Decoder - Added support for the [ICS Decoder](https://github.com/Dysonian-Lab/icopy-x-ics-decoder), a USB dongle that reads SEOS SIO credentials and returns the decrypted PACS payload over serial. - Added SEOS downgrade writes: the iCopy-X parses the SIO, extracts the Wiegand frame and writes 48-bit payloads to iCLASS Legacy or 26-bit payloads to T5577 blanks. It detects the blank on the coil and verifies the write by reading it back. - Moved decoder detection to a background thread. - Fixed a grey-screen hang on exit. ### Quality of Life - Fixed firmware updates failing with error `0x05` when the IPK was copied from a Mac. The updater picked up AppleDouble `._` sidecar files first. - Fixed the companion client zips so that `resources/`, `dictionaries/`, `lualibs/` and `luascripts/` sit next to each platform binary. Without them, `hardnested` and `autopwn` on macOS had no bitflip tables. A sector that took about an hour and a half now takes about a minute. - Updated the bundled Proxmark 3 firmware to Iceman v4.21611 with the iCopy-X patches. - Restored the factory client in the no-flash IPK. - Fixed the ChkDic timer showing `mm'ss''` instead of `mm:ss`. ### Localisation - Added a switchable UI language, with French as the first translation. Strings load from `data/lang/.json` and any missing string falls back to English. A new language is a drop-in JSON file. - Added Settings > Language. The choice persists across reboots, and switching updates the main menu immediately. - Added translations for the known Proxmark client status phrases, applied after normalisation. Hex and structured output are untouched. ### Plugins Two new plugins ship with these releases, and two existing plugins have been updated: - `manage_dictionaries`: copies the Iceman T55xx and MIFARE Classic default dictionaries onto the SD card, adds keys to either, backs them up to `backup_dictionaries/N/`, and clears the user keys. - `mfc_recovery`: MIFARE Classic key recovery at three levels of thoroughness. The fullest uses Iceman's `mfc_default_keys.dic`. - Added block cycling and progress tracking to `T55xx_block_reader`. - Reworked the `T55xx_block_writer` write flow.
