Unable to get the device into update mode
 

My N900 is not booting up. I tried connecting my phone to the laptop while pressing the "u" Key but the phone never goes into the update mode. i was thinking of flashing it. On windows i get Nokia USB ROM Device diconnected error while installing the driver.

Not Sure what could be wrong here but any help would be appreciated.

Thanks in Advance

Re: Unable to get the device into update mode
 

Try cold flash. Here are "2nd" and "secondary" parts.

Remove battery, run flasher-3.5 in coldflash mode, connect n900 with usb cable.. and then you need to insert-remove-insert-remove-insert battery until operation will be done (you may notice some vibration and debug info in console). It's hard for first time. (no dick jokes)

P.S. there may be a lot of windows popups about different plugged devices. Also you need to remove-insert usb cable, if windows stops beeping when the battery is inserted.

Thanks...

I tried but following is the output on my command prompt

C:\Program Files\maemo\flasher-3.5>flasher-3.5 -F image.bin -u

Sorry for bring a naive but can you tell me the exact steps here :(

Re: Unable to get the device into update mode
 

image.bin file is not the image.bin file you have. Read this first and obtain firmware images here.

You will need to download the firmware images first and place them in the same directory as the flasher tool and then type the exact name of the firmware image you download (assuming you should always get the latest one which is PR1.3), you then follow the guide.

Though in theory I really do not think cold flashing using that technique is required. I have had successes with flashing my N900 just by removing battery for 30 or so seconds, replacing the battery and quickly holding down the u key whilst the microUSB cable is plugged in on both ends (i.e. computer and N900). I have successfully flashed it entirely with the regular flashing method rather than cold flashing though I'm using linux.

I finaly got the command right... I unpacked the image and got the files..

But it was a no go.. i inserted and removed the battery plenty of times the command completes till

Re: Unable to get the device into update mode
 

Finally Got it to work Somehow... Not sure how but flashed my phone successfully. All my contacts and calenders are still there along with the files. I ran the following command
C:\Program Files\maemo\flasher-3.5>flasher-3.5 -F RX-51_2009SE_20.2010.36-2.004_
PR_COMBINED_004_ARM.bin -f -R
Is there a way i can completely wipe out everything on the phone and get it back to factory settings.

Re: Unable to get the device into update mode
 

If you want to flash your device fully you shouldn't be specifying any other parameters for flashing apart from flashing the fiasco and maybe reboot after successful flash.

Your contacts and calendar information are stored in a different partition where the fiasco image does not flash.

There are two ways to completely wipe everything on the phone and get it back to factory settings:

1) unverified: Settings> Clear Device (look for blue arrow pointing downwards from the word Settings near the top of the screen).

2) flash both fiasco and eMMC (eMMC image needs to be downloaded separately) using the methods prescribed in the wiki for flashing the device.

Congrats!


To wipe all personal data it's better flash eMMC + combined then.
Read the wiki for further details.

Hi all, i'm having this same problem and have run it on win x64, x86 and get the same errors even using libusb to install the drivers

1) Removed battery
2) ran "flasher-3.5.exe -F RX-51_2009SE_1.2009.41-1.VANILLA_PR_EMMC_MR0_ARM.bin -f"
3) press 'u' and connect USB cable, N900 starts
4) on computer

Code:
flasher v2.5.2 (Oct 21 2009)

After much ado...i decided to move to a linux platform to try it out and i get the same error even while running it in sudo mode.

I have also seen the cold flash option, but it was only advised to do it if a certain boot-loader test failed, mine passed which means i do not need to continue along that path. So please what am I missing? Can anyone help?

Re: Unable to get the device into update mode
 

1. Don't remove the battery! Battery MUST BE FULL CHARGED
# Install Flasher for your OS (Linux, Mac OS X or MS Windows)
# Grab the recent Vanilla eMMC image (.bin file) from the Nokia repository. There isn't always a new eMMC image for a new COMBINED image, as usually the content of eMMC doesn't change with new versions of the system.
# Navigate to the directory where the image file was saved (Windows users: if you don't know the full path to the image, copy it to the flasher directory)
# Execute the following command (in Linux you have to be root! On windows you have to be admin!): Replace RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin with the name of the most recent VANILLA file you downloaded
