===== Introduction =====
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, an LED somewhere on the phone will light up for approximately one second, and then turn off.

==== 900i/700i Series ====

=== SPECIAL NOTE FOR N902i SERIES: ===
The N902i series of phones (N902i, N902iS, N902iL, N902iX) have difficulty connecting to PC. If the phone does not connect properly, there are a few techniques you can try. The results are generally random as to whether these work, and you may need to try the same method multiple times before the phone will connect.
  * Use a Linux computer instead of WSL (this is a MUST)
  * Boot up the phone once, shut down the phone, then quickly remove the battery and plug it into the PC
  * Plug the phone into the PC with the battery inside, then remove the battery
  * Follow the steps above, but right after the phone light flashes once, reinsert the battery
  * Use the battery in a different phone, boot up that phone, then remove the battery and use it with the phone you are trying to dump
  * Cover the ground contact for the phone battery, reinsert the battery, and plug into PC
  * If you don't have a battery, boot the phone with an external power supply, remove the power, and quickly plug it into the PC
If you are still having trouble after attempting these steps multiple times, you can reach out in the Keitai World discord channel for help.
