how to flash using C+F keys method


important:

DO NOT USE THIS WITH ANY BOOTLOADER OTHER THAN 4.10. you've been warned! 

DISCLAIMER: NOT RESPONSIBLE FOR ANY PROBLEMS. however, i'm willing to help if i can.


instructions:

1. format (fully) a CF card that is at least 64 MB. use FAT16 (xp just calls that FAT)! 
2. you must format the card even if it was already FAT16! 
3. NOW CONFIRM YOU HAVE BOOTLOADER VERSION 4.10. the next steps will help you.
4. go to control panel on your 900c, NEC firmware info applet and read the bootloader version there.
5. if it is not version 4.10, you stop here and do not go further. you need the external updater bootloader to flash anything.
6. if you have 4.10, you can now copy XIP.BIN to card. this is the OS image.
7. insert the card in the 900c.
8. hard reset 900c by removing all power (main battery, backup battery, ac adapter) 
9. before reinserting main battery (do not touch backup battery yet!) or ac adapter (easier), press and hold C and F keys on the 900c. 
10. make sure the battery lock is locked.
11. give power to the 900c while still holding the keys until the 900c switchs on - on its own! no need to press the power key. 
12. if it doesn't switch on within 5 secs, release the keys and it will turn on then (again on its own). 
13. it should tell you that it is searching for bootloader update. of course it won't find this file so it will continue searching for OS update, which should be found on the card. it will flash it in automatically. 
14. when the process is completed, it should boot the OS automatically. eject card, don't forget to reformat it again! 
that's all! 



NOTE: i don't recommend doing a bootloader flash with this, unless you are absolutely sure you have bootloader 4.10.
generally you should just do an OS image flash.


troubleshooting:


1. if the update is not done, then try another CF card.

2. if the flashing process of the OS image stops for whatever reason, restart and repeat the process from step 8.
