I followed http://wiki.maemo.org/Overclocking#Flashing_using_PC, tried to reflash the pr 1.3 image to my bricked n900.

however, flash had a message that says Suitable USB device not found, waiting, and after i plugged the n900 onto usb cable, nothing happened.

it doesn't seem like my windows 7 (32bit) laptop was recognizing the n900 device, and I was using the machine to sync with the phone just a few hours ago!

Any ideas? Thanks!

well, if your device is bricked there is nothing more to do. just put it to your bookshelf or use it for a brick wall or fireplace or similar...

When u connect the USB, is the device like..... Dead???
If there is any bit of life or somethin then just try with an XP Machine as a last resort. The flasher has issues in Windows 7 (esp 64 bit. Some have managed flashing in 32 bit but, nothin goes in trying right). If u wish, you could use a Virtual XP Machine within ur Windows 7.

try doing it from inside the virtual WinXP

I have a windows 7 32bit flashed my N900 7 times till now:
1. the process is extensive but quite comprehensive
2. you'll need to know ur imei for software downloads
Now roll up ur sleeves we'll bring ur N900 back to life!:
1. go to tablets-dev.nokia.com/nokia_N900.php
2. there r clear instructions on how to find and enter ur imei
3. after that throw the eula in a trash and click I agree
4. find RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM.bin latest global release for Maemo 5 and click on it then download it
5. find RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin latest vanilla emmc content click on it then download it
6. place ur 2 .bin in the folder where maemo flasher was installed (e.g. C:/program files/maemo)
Now u should have the 3 required files for flashing:
1. flasher 3.5
2. RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin emmc content
3. RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM.bin fiasco (OS)
The following procedure is the important one:
1. Be sure ur N900 has at least 50% of its battery charge
2. disconnect any internet connections (this is the issue with windows 7)
3. go to start menu then in the search type maemo flasher u should find it.
4. click on it it will open a cmd window
5. connect ur usb cable in ur pc not in the N900 yet
6. open ur N900's keyboard and press u button and keep holding it while plugging the usb cable in ur N900
7. faded Nokia logo with usb icon on top right corner shall appear
8. ur cool stop holding the u button now or ull suffer from finger constipation :P
9. returning to maemo flasher issue this command:
flasher-3.5.exe -F RX-51_2009SE_20.2010.36-2_PR_COMBINED_MR0_ARM.bin -f (u can copy and paste it in maemo flasher)
10. HIT ENTER the windows 7 screen about allow and don't allow should appear click allow another cmd window shall appear it will show the flashing status takes about 5mins
11. after it finishes the other cmd window will close and u return to maemo flasher issue this command:
flasher-3.5.exe -F RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin -f -R
12. the same other cmd window will appear showing flasing status after it finishes ur N900 will reboot
13. disconnect ur usb cable close flasher be happy
Now a bit work with ur N900
1. once ur N900 reboot open the ur battery cover, remove the battery, and yep we're not letting it boot
2. with the battery removed press the power button long press it for 5 seconds to leave away any static electricity from usb connecting
3. count 30 seconds then plug ur battery back do not put back the cover.
4. boot ur N900 by pressing the power button ur N900 should boot happily although it will take time with the 5 dots in the booting process
5. after it boots ull get the seetings of time and date etc...
6. put the cover back and brick ur N900 again :P
p.s. if ur led flashes orange when ur N900 boots after flashing NO WORRIES just repeat the takeoff battery static electricity process

If you're using custom EMMC just rename the custom emmc to RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin

Take a look here, Its the link to the author of BACKUP, "RobbieThe1st". He's got a flashable img in the post from which u can solve bricked state via maemo flasher. Even though I haven't checked it, hope it will come handy to you.

Yes and no - My image(probably) won't let you get into Maemo. It's simply there so you can easily restore previously-backed-up images quickly.

@ammyt

Thanks for the tips. However I've been trying to flash my emmc (after rootfs) and the point is it just won't finish booting up.

I have tried your explanation, removing the battery etc, and also have tried wiki's which is leave as IS and wait. None work. After giving up on booting I bring phone back to life but know emmc is not booted up because my password is still the same and not reverted to the 12345 original.

Also, now I have Healthcheck not loading anymore. Could someone please point in me in right direction?

Are you saying you end up with suitable USB not found?

The password may be a separate issue. Does it work?
