Searched and read the forums, read the wiki, and still do not feel prepared at all to flash the device.

I need a step-by-step guide
(One which hopefully can be used for other beginners needing help)
Would really like if someone were to help
(All I know right now is I do not want to reflash the eMMC)

First things first, what happens when you flash?
Everything is lost, even backups?

Guide please

i was in your shoes but you need to re read the wiki it cant get any simpler than that. Seriously read it a few times its not hard at all

Alright, fair enough.

However, can you answer the question about backups?

If you back up your phone, and then reflash it, will the backups be deleted?
Or will I be able to restore to how it was before (using the backups)?

check your inbox i sent you a step by step guide how to flash your device - PM if you need any more help

i have a prob too maybe u can help me my bluetooth n wlan cant connect others told i have to reflash my n900 can u help me?

+1. Follow it step by step and you will be fine! If your going to flash the eMMC copy you backup folder to your computer as it will be deleted.

where's the steps by step thing?

flashing your device is really a simple task
b4 starting the flashing process you'll need to get 2 important files
1) the fw - the FirmWare for you device can be downloaded from here - http://tablets-dev.nokia.com/nokia_N900.php
just enter your imei number which is a 15 digits number located under your battery
2)the FW flasher - http://tablets-dev.nokia.com/maemo-d...-downloads.php
download and install it to your pc

now comes the fun part Flashing
1)move the FW file we downloaded earlier to the maemo flasher folder - by default it is located at c:\program files\maemo\flasher-3.5\
2)turn off your device
3)press and hold the U button on the N900 keyboard
4)while pressing plug the usb cable to the device and PC
5)run the flasher program - it is a cmd based software so you won't see any GUI
input the next command -
flasher-3.5.exe -F XXXXX -f -R
the XXXXX marks the place for the name of the FW file so just replace the XXXX with the File name of the FW ( usually it looks like this flasher-3.5.exe -F RX-51_2009SE_2.2009.51-1_PR_COMBINED_MR0_ARM.bin -f -R )
6)let it be - DO NOT touch the cable while it is working
7)after about ~4 mins your device is ready
8) let it reboot
You're Done

thank u very much ill try it later ...

Cool and good luck with your N900
