A Quick Introduction to the Blue Angel (BA) Device

This page is created to help beginners understand the basics of a BlueAngel device

Soft Reset

Put your stylus in the hole in the lower left corner where it says “Reset” Soft Reset will reboot your device just like when you reboot your PC. No data will be lost, under normal circumstances that is.

Hard Reset

Hold down the Power button (Top Right corner) and at the same time put your Stylus pen in the hole where it says “Reset” (Lower Left corner).
Hard Reset will delete all data you have put on the device, Programs, Settings, Mail, SMS, MMS, etc., so be careful and make a backup before doing this.
After a hard reset, you will have a complete clean new install of Windows Mobile on your device.

Things that are not deleted

  • Data on \Storage Card
  • Data in \Storage folder

Boot Loader Mode

You can enter or exit bootloader mode by pressing the camera button, power button and then the reset button and hold for a few seconds.

If the above won't work, this worked for me (thanks to all the gurus in the forum): press and hold power+record+camera the same time and then reset


  • A ROM is something you download from your vendor’s website, or you can also download one from this site.
  • A complete Ship ROM contains the Windows Mobile operating system, Radio Stack and the Extended Rom.
  • ROM versions are numbered something like this: 1.22.167
  • A complete Ship ROM is called something like this: BA_WWE_DT_12200_167_10602_Ship.exe

Note: The numbering of ROM’s is Operator/Vendor independent, thus 1.31.000 is not necessarily newer or better than 1.22.167

To read more about upgrading or changing your ROM, see here: BA_GettingStarted

Extended ROM

  • The Extended ROM is a data folder on your device that you by default can not see
  • It’s hidden because your not suppose to tamper with it
  • It contains programs and small upgrades that will install every time you reset your device
  • Most of the programs are put there by your telco, and also contains the telco logo's and settings
  • Files in the Extended ROM are put there depending on which ROM version you have installed
  • Extended ROM is included in the ROM upgrade file you download form you Operator/Vendor
  • A higher Extended ROM version does not mean it is better

You can however modify (or "cook" as we like to call it) your Extended ROM, see here for more info: Understanding Extended ROM

.CAB files (cabinet files)

  • .cab files are files used to install programs
  • .cab files are similar to what you might know as setup or install files from your PC
  • .cab files can be downloaded directly to your BA with Wifi or GPRS, you can also transfer them to your BA using File Explore on your PC
  • .cab files are not supposed to be unpacked/unzipped on the PC. Copy the intact .cab file as you downloaded it directly to your BA

What is flashing a ROM?

Flashing a ROM is the process of puting a new ROM on your device, otherwise known as upgrading.

What is a Cooked ROM?

The term Cooked ROM means that the shipped Extended ROM has been modified with other files Check The Extended ROM Kitchen for more information

What is a Baked ROM?

The term Baked Rom means that the original shipped complete rom (CE, Extended and radio) has been modified A Baked rom could have a CE rom from one operator, a Radio stack from a second operator, an Extended rom from a third operator or even a "cooked" extended rom.

What are Type I and Type II ROMs?

A Type I ROM is a ROM that can be easily modified with the xda3nbftool.exe to match the Country Code or Language Code on your device so you can flash it.

A Type II ROM is a ROM that when used with the xda3nbftool.exe it will gererate a Header Error and thus can not be flashed by you (unless you are aware of certain tricks that you can read about on wiki)

What is the difference between the PDA2k (XDAIIs, Qtek 9090, SX66) and PDA2K EVDO (Sprint 6600/6601), Blueangel and Harrier

The PDA2k (Blue Angel: PH20B, PH20B1) is a GSM phone, with GPRS and wifi.

The PDA2k EVDO (Harrier: PH20A1, PH20A2) is a CDMA phone, with EVDO and no wifi.

Basically, you get the one that is right for your mobile service provider. In Canada, for instance, Rogers and Fido use GSM, and Telus uses CDMA.

Should I do a restore from backup after I have upgraded my rom to a new version?

Short version N0

Long Version; If you restore a backup after a rom upgrade you are going to downgrade your software to what you had before the upgrade. Thus do a rom upgrade, sync your outlook, re-install your applications, re set your local settings.

Yes you can do it another way but at the momment you are reading BlueAngel For Beginners.
