An ExtROM trick

[HyperMalac]

Hi there!

Today I've got an idea. If I unlock the extrom, install all my programs and totally config my wizard, the backup my system with SPB Backup for WM5.0, then put the backup file into the ExtROM and write a config.txt, and make a HardReset, the backup file should be installed automatically.

Or ExtROM only works with .CAB files?

EDIT:

NOW Testing.....Will post the result

How are you going to unlock the ext-rom?

And what about the post AKU2 roms?

There's a fix for that, too. Don't recall where off-hand.

Ok. NowI have time for testing this idea. But I have some problems.

When you open the EXTRom you can see a config.txt which contains the cab configuration datas.

Like this:

CAB: \Extended_ROM\T-Mobile_Network_Customizations.cab

I'm using SPB Backup what is creates backup files in .exe format. So if I want to do a full backup and I want it to autorun after a hard reset, I must do edit this config file right?

Maybe the config file should be like this:

EXE: \Extended_ROM\Full_Backup.exe

All I mentioned here is right, or I'm wrong with something?

All I mentioned here is right, or I'm wrong with something?youare correct,but it wont work because the spb .exe has an input dialog before starting to restore ,therefore it will crash the extended-rom when trying to install the .exe,the solucion is to hack the .exe file and remove the dialog input so it can install witout any user help.

Not 100% sure on this as I have not tested it but could you not unlock the LCD while running the EXE then lock it afterwards if needed?

Something like.


LOCK:Enabled
CAB: \Extended_ROM\1.cab
CAB: \Extended_ROM\2.cab
LOCK:Disabled
EXEC:\Extended_ROM\backup.exe
RST: Reset


or may be copying it to the MiniSD or internal storage would work better?


LOCK:Enabled
CAB: \Extended_ROM\1.cab
CAB: \Extended_ROM\2.cab
CPY1:\Extended_ROM\backup.exe
CPY2:\Somewhere_On_Device\backup.exe
LOCK:Disabled
EXEC:\Somewhere_On_Device\backup.exe
RST: Reset


Not tested any of this as I just use OMA and CAB's to do all I need but it's just an idea.

maybe your extended rom is diferent [since there is many versions] and will let you input ,i know it use to work in the pda2k extended-rom,let me know the results.
