 ===== Introduction ===== ===== Introduction =====
-Docomo phones by NEC use a very similar bootloader to [[phones:docomo:panasoni|Panasonic]] Docomo phones. When an NEC phone is properly connected to a debug cable, it will light up for approximately one second, and then turn off. +NEC Docomo phones generally run on a customized form of Linux. They use a bootloader related to the one used in [[phones:docomo:panasonic|Panasonic]] and [[phones:docomo:casio|Casio]] Docomo phones. When an NEC phone is properly connected to a debug cable, it will light up for approximately one second, and then turn off. 
-^ Phone Model ^ Extractable? ^ File System (Main Storage) ^ FTL (Flash Translation Layer) ^+ 
 +Note: We currently do not know how to extract NAND data from NEC phones between approximately N902i - N703iμ. These phones are also challenging to connect to PC. It may take multiple tries for your PC to detect one of these phones. Sometimes, these phones connect better after booting up once.
