Note: BROWNOUTS OR ANY POWER INTERRUPTIONS MAY CAUSE PERMANENT DAMAGE TO YOUR DEVICE!

Make sure No Simcard is inserted in the dongle.

Plug the USB device at the back of your PC or in a Laptop what ever you are using for me I'm using a Laptop running in Windows 7.

After plugging the device let your computer or laptop finish installing the device and wait for the confirmation. “Device is installed & ready for use”

Go to Start\Control Panel\System\Device Manager\ Make sure dongle is installed with drivers.
For Windows 7 install the Win7 Tool can be found at the bottom.

After installing the Win7 Tool download ZTE627 Unlock and it can also be found at the bottom.
Unzip the downloaded "ZTE627 Unlock" and then run the Flash Update
Make sure you already installed the Win7 Tool for Windows 7 user before you use the Flash Update because it may damage your device but I think you can't use the Flash Update for windows 7 without installing the Win7 Tool because you can't click the download button.
After running the Flash Update you can see a download button at the lower right of the program click it and it will flash the device.

Do not unplug or use the PC because it may damage your device!
When it is finish it will tell you so just wait, for me it took 18 minutes to flash the device.

Unplug it and put other SIM of your choice.

To use your openline modem, make a new profile:


SMARTBRO SIM:
APN: SMARTBRO

SMART PREPAID SIM:

APN: internet

GLOBE

ACCESS DIAL: *99#

If you don't like to use the Globe software for going to the internet
with Smart or any other provider after overwriting the flash memory,
why don't you use the Telstra software from ZTE Australia:

GUIDE ON HOW TO RESET CODE

How To Hard Reset The N900 To The Factory State

There is no seemingly easy way to do this and I really hope Nokia is  doing something about it. That being said, how do you go about  accomplishing the task? The answer is to flash both the N900′s OS and  the 32 GB mass memory. This can be done on a Mac, a Linux or a Windows  machine. Since windows is the most popular OS, I will show you how to do  this via Windows.

Before we start, please note that this would be done using the command line interface, it may seem tricky but let me assure you that it is simply enough for anyone to accomplish.


  • Download  and install the latest version of Maemo Flasher  (e.g.  maemo_flasher-3.5_2.5.2.2.exe). Since this is a command line application  you will see no shortcut on the desktop or in the Program Files option  under the Start menu.


  • Next, Download  the latest firmware (.bin) file, it will look like  “RX-51_xxxxx_ARM.bin”. You will need your IMEI  number to access the  downloads, it can be found on the box or by going to Settings > General > About Product.


  • Also download the Vanilla eMMC image (.bin file) from the same page.  It will look like  “RX-51_2009SE_1.2009.41-1.VANILLA_PR_EMMC_MR0_ARM.bin”


  • Save both  to C:\ProgramFiles\maemo\flasher-3.5\. My suggestion is to rename them to something simple such as RX-51.bin for the firmware and R.bin for the eMMC, this will make typing the commands easier later on.


  • Make sure that the battery is fully charged and switch off the device.


  • Open the Command Prompt by going to Start then Run and type cmd,  then press Enter.


  • Change directory to the flasher’s program path by entering:


cd "C:\ProgramFiles\maemo\flasher-3.5"


  • Connect the USB cable while holding the ‘u’ key on the N900. Within  an  instant  you will see a USB icon on the top right corner of the  N900. Now  leave  the ‘u’ key.


  • Run the following command:


flasher-3.5.exe -F RX-51.bin -f -R


  • I typed RX-51.bin because I had renamed the file earlier, otherwise  it would have been: (this was the name of the latest firmware, the name  may vary after a new firmware comes out)


flasher-3.5.exe -F RX-51_2009SE_2.2009.51-1_PR_COMBINED_MR0_ARM.bin -f -R"


  • You will see text similar to the one below on your PC.

  • The update will take about 3 minutes after which the N900 will reboot  and display the Welcome screen with Regional settings.

The next step is to flash the Mass Storage or the eMMC.  The first few steps are identical to the way you would flash the  firmware. If you are following on from the above and already have the  command prompt open, you can directly proceed to step number 3.


  • Open the Command Prompt by going to Start then Run and type cmd,  then press Enter.


  • Change directory to the flasher’s program path by entering:


cd "C:\ProgramFiles\maemo\flasher-3.5"


  • Connect the USB cable while holding the ‘u’ key on the N900. Within  an instant  you will see a USB icon on the top right corner of the N900.  Now leave  the ‘u’ key.


  • Execute the following command:


flasher-3.5.exe -F R.bin -f -R"


  • I typed R.bin because I had renamed the file earlier, otherwise  it would have been


flasher-3.5.exe -F RX-51_2009SE_1.2009.41-1.VANILLA_PR_EMMC_MR0_ARM.bin -f -R


  • You will see text similar to the one below on your PC.


How To Hard Reset The N900


  • The flash will take around 1 minute after which the device will  reboot.


  • The bright Nokia screen will come up on the screen with the  USB  icon on the top right followed by progression dots with yellow LED   blinking for a few seconds. The device will then turn off and go into   charging mode with the yellow LED blinking (NOTE: If the device appears   to reboot, unplug the cable.)


  • Unplug cable and wait for device to turn off completely. You  may hear a sound (punk) of the device turning off.

That’s it. You have now hard reset the N900 to the factory state.  This procedure can be used to update the firmware on your device as  well, if you wish you can leave formatting the eMMC if your intention is  only to update the firmware. Please make sure that the battery on your  N900 is completely charged, otherwise you might brick it.
