We put it back in the Thinkpad X230, and boot it. Now our AR9285 card is patched and ready. PCI_SUBSYS_ID 3B1A:8910 will become 8680:1113ĭon't forget, there are 2 OCCURENCES of each to find and replace by.Īnd now we write back the modified eeprom dump file into the wireless card, using iwleeprom tool:.Now something IMPORTANT, the eeprom dump file is byte-flipped, which means, if we want to look for "168C", we will look for "8C16". In the menu "View" -> "Group Data As" -> "Words", it's just a preference. Now it's time to open the eeprom dump file with ghex, find and replace vendor/device/subsystem IDs: We keep the original intact, and we'll work on a copy:Ĭp AR9285-original.eeprom AR9285-patched.eeprom The file is owned by the root user, but you can change it back to a normal user owner (chown). Saving dump with byte order: LITTLE ENDIANĠ000 Ġf80 ĮEPROM has been dumped to './AR9285-original.eeprom' Then, we download the tool source code that allows us to read and write EEPROMs, iwleeprom: Sudo apt-get install build-essential ghex Now we will dump the AR9285 EEPROM into a file, modify that file(to make it look like the N6205), and copy it back to the wireless card. This will give us the pci slot used by the cards, for me: 03:00.0Īnd we look for the same pci slot, for me: 03:00.0 We start with the Centrino Advanced-N 6205 by putting it inside the spared laptop. Spared Laptop with no restriction, and Ubuntu 16.04.3, and Atheros AR9285 wireless card.įrom now on, we'll use the spared laptop.įirst we need to identify both wireless cards.Lenovo Thinkpad X230 with BIOS whitelist (v2.67), and MacOS Sierra and its original Centrino Advanced-N 6205 wireless card.But in this tutorial, I will use the Intel IDs. However, there is an Atheros Card which is whitelisted by Lenovo 168C:002B:17AA:30A1 so its IDs can be use to flash the EEPROM card. We copy the vendor/device/subsystem IDs of the Intel card into the EEPROM Atheros card. The idea here is to use a Atheros AR9285 wireless card, and make it look like a Intel Centrino Advanced-N 6205 Wireless card.
