[JAM, MDA Compact, S100 Software Upgrading] HBK:
Ok... I think you won't get many replies, because what you are looking for has already been posted here many times. The big problem is that the info could indeed be burried inside very huge threads, so it will take a lot of reading to find it. But I'll try to summarize...

You will need to download the latest ROM for your Magician. Most likely you will want to stay with the ROM specifically designed for your device, for example from I-Mate. That way at least you can perform the ROM upgrade without any fuzz.

Log on to I-mate (or whatever) and download the latest ROM. Reboot both the PC and the Magician and execute the installer. After about 20 minutes, you are done.

You'll want to have access the Extended ROM, where all the standard settings and programs are stored. To do that, you will have to copy Extended ROM to a safe place, because when you have done the Big Storage thing, Extended ROM is gone, and so are these files. In order to get to the Extended ROM, you'll have to:

Hard reset the device after the ROM upgrade, as you are told on screen when the upgrade is finished. This means pushing the power button, while using the stylus on the reset button, located at the bottom of the device. The Magician resets and the setup routine begins. You are asked to perform calibration of the screen and time zone, before the OS is ready to run. Then, a few seconds after you see the Today screen, a 3 seconds countdown appears. At this exact moment you must perform a reset, which simply means pushing the button with the stylus again, this time without using the power button. Now the device will restart without installing files from Extended ROM, and more importantly, without hiding the Extended ROM.

Connect the Magician to the PC using ActiveSync and copy the folder Extended_ROM, located at root, to your SD card and make a backup on your PC. You are now technically ready to take on Big Storage...

But! Beware that If your skills are at the level you suggest, you may end up killing your Magician, instead of gaining Big Storage. This has happened to a lot of people, who then had to struggle their way into getting their device functioning again. Be absolutely sure that you are willing to take the risk, because you may end up cursing yourself for doing this.

Still happy going on? Ok... What's coming next is my edit of other peoples work, so I don't take any credit for it. Unfortunately I don't remember who wrote it either...

You will need to download and install the 'Backup Tools1' found on the FTP part of this forum, to perform the following steps. ftp://xda:xda@xdaforums.com/Magician/Tools/

Backing up your current ROM:

Make sure you backup your ROM for 2 reasons. Firstly, because you will need to edit part of your ROM in order to be able to flash your Magician with the no extended ROM, and secondly, because you might need it either for flashing your phone in case of a malfunction so you can send it back under warranty with the original ROM, or for helping you to flash future upgrades.

Backing up your ROM can be done by connecting your Magician to the PC through the data cable when you first uncheck the USB connection of active sync.

If your Magician connects with ActiveSync because you didn't uncheck the USB connection in the active sync connection settings then you will not be able to backup your ROM to an SD memory card.

1. Before connecting your Magician you should bring it into the boot loader mode. This can be done by simultaneously pressing power + camera buttons and at the same time the soft reset button with the stylus.

2. After connecting your Magician to the PC through the USB in boot loader mode and having your SD card inserted into the Magician, you run romupdate.exe.

3. Then choose the USB connection in the connection settings of romupdate.exe window and click on ok. After that a terminal window will popup in that window.

4. Type d2s and press enter. Your Magician will start copying the ROM to the sd card. The screen of your Magician will be dark (no light), but you will see it counting up to 100%. When it reaches 100% it will say it is calculating the checksum. Give it some time till its done and it will say checksum ok.

5. After finishing the transfer of your ROM from your Magician to the SD card, put your SD card into an SD card reader connected to your pc. Your pc might pop up a warning message that says your SD Card is not formatted would you like to format? Click No and open a Command prompt (DOS) window.

6. Change directory to your root directory (cd c:\) and run the command ntrw read your_rom.nb1 x: where x is the drive letter of your sd card. That command will create the ROM Backup file of your ROM into your C drive root directory by the name of your_rom.nb1. Make sure you keep your_rom.nb1 in a safe place and use a copy of that file for the rest of the procedure. Note that after finishing the copy from your SD card to your_rom.nb1 file ntrw might give you an error, just don’t pay attention to it.

Patching you ROM:

1. Use Hex Editor to open the your_rom.nb1 file on your PC

2. Use the FIND function to locate "02 00 00 80 00 20 20 00 00" and change it to "02 00 00 b8 01 20 20 00 00". Note that this is a hex search, not ascii, so enter the search as 'Bytes'. You will find this pattern twice inside your ROM, and both should be changed.

Transferring your no extended ROM File from your hard disk to the sd card:

1. Get the fixed no extended ROM file to your C drive root directory run the command ntrw write fixed.nb1 x: in the command prompt window where fixed.nb1 is the filename of your fixed ROM and x the SD card drive letter. Wait till it finishes and move to the final step.

Flashing the Fixed no extended ROM to your Magician:

1. Put your SD card into your Magician and get your Magician to boot loader mode again (power+camera+reset buttons). On your unlighted screen you will see it says serial wait and after some seconds it will say (Press Power to flash).

2. Do as it says and it will start flashing. When your Magician reaches 100% flashing, it will check the checksum. Don't worry about the message Checksum failed - Flashing failed and soft reset your Magician. Please notice that the first boot may take something like 5 minutes, so don't worry about it.

When your device reboots, you now have a Big Storage Magician! If you need parts of the Extended ROM installed, like fax, MMS or whatever, you can simply click on the files inside the Extended_ROM folder you backed up earlier and they will install.

My guess is that by now you will have realized that there IS no easy way to get the Big Storage. Even though it sounds harder than it is, it does take some time and care to perform right.

There are other ways to do Big Storage, but this is the clean way. You don't have to rely on patchers, and you won't have your boot screen turned into something that another user think looks cool. This is the real deal with only 4 bytes getting changed, and you know for sure you'll have the right Extended ROM available as a backup, and that is as good as it gets! :)
