SOLVED- EXT-ROM Unlock & UnHide - 2.xx

[AbuYahya]

after few days of playing around, then found a solution to WRITE to Ext-ROM which persists after soft-reset.
All praise and thanks are to God the Most High.

Here is the solution; Tested for prophet ROM2.15.13.27 -G4 but should work for over chipsets and even other handsets e.g Wizard

To Unhide Ext-ROM --- (this is already known by most- but include for completeness)

Need following registry changes:

HKEY_LOCAL_MACHINE \System\StorageManager \AutoLoad\TRUEFFS_DOC1
"Bootphase"=dword:2

HKEY_LOCAL_MACHINE \System\StorageManager \Profiles\TRUEFFS_DOC1
"MountHidden"=dword:0


To Rename EXT-ROM

HKEY_LOCAL_MACHINE \System\StorageManager \Profiles\TRUEFFS_DOC1
"Folder"=string:Storage
--- can call it anything you like instead of "Storage"


To Unlock the EXT-ROM
HKEY_LOCAL_MACHINE \Drivers\Builtin\TRUEFFS _DOC1
"SoftwareWriteProtect" =Dword:0

THIS key is the mainchange that will enable write protect, but it keeps reverting after softreset. To get around this, will need to change the following also.

HKEY_LOCAL_MACHINE \Drivers\Builtin\TRUEFFS _DOC1
"AutoDPDMode"=Dword:0

Then Softreset.
Now should be able to write and install to Ext-ROM/Storage

If any problem can return the last key to original value
HKEY_LOCAL_MACHINE \Drivers\Builtin\TRUEFFS _DOC1
"AutoDPDMode"=Dword:1
-----not sure what this key does??
then soft reset again.

this worked for me . try at own risk!!

Enjoy

That's a very old and known trick.
But: it does not work on the Wizard !
Prophet, etc. all OK

Does that mean that i can install a dutch rom, by downgrading my G4 device.

Hopefully it does.

Hello,

i installed the AKU 2.3 Rom "2006-10-14_Upgrade_Rom_lvsw_edition.exe" and don't habe these entrys in my registry:


HKEY_LOCAL_MACHINE \System\StorageManager \Profiles\TRUEFFS_DOC1
"MountHidden"=dword:0


To Unlock the EXT-ROM
HKEY_LOCAL_MACHINE \Drivers\Builtin\TRUEFFS _DOC1
"SoftwareWriteProtect" =Dword:0

THIS key is the mainchange that will enable write protect, but it keeps reverting after softreset. To get around this, will need to change the following also.

HKEY_LOCAL_MACHINE \Drivers\Builtin\TRUEFFS _DOC1
"AutoDPDMode"=Dword:0

this key is in my device at:
HKEY_LOCAL_MACHINE \Drivers\Builtin\TRUEFFS1
"AutoDPDMode"=Dword:1

is it the same key?

thanks
John

Hello,

i installed the AKU 2.3 Rom "2006-10-14_Upgrade_Rom_lvsw_edition.exe" and don't habe these entrys in my registry:


I instaled the same ROM so abit strange you don't have writeprotect key. Possible options maybe perform backup and hard reset and then recheck for the latter key....Or....just make the keys.

I think I added this key also myself but not 100% sure.
HKEY_LOCAL_MACHINE \System\StorageManager \Profiles\TRUEFFS_DOC1
"MountHidden"=dword:0


As for writeprotect key then try adding. if the dword remain at 0 after soft reset then should work. if not try changing the Dword for AutoDPDMode form 1 to 0, aswell as the softwarewriteprotect key as below


To Unlock the EXT-ROM
HKEY_LOCAL_MACHINE \Drivers\Builtin\TRUEFFS _DOC1
"SoftwareWriteProtect" =Dword:0

HKEY_LOCAL_MACHINE \Drivers\Builtin\TRUEFFS _DOC1
"AutoDPDMode"=Dword:0

hopefully should work.

sorry to hear it doesn't work on Wizard.

If it was well known then maybe some-one should add it to the WIKI page. As several have asked how on a few threads with no replies both here and BUZZdev.net.

doesnt work on my Jamin with the 16Mb_AKU2.3_GSM02.30.21_Extrom-4PDA.ru.exe rom

I had to use buzz's unlock tool to let me write to my extended rom.

[Putra]

I have upgraded to the PDAMobiz 16MB ROM. Unhiding the extrom via the registry entries work. But unlocking it doesn't.

I too do not have HKEY_LOCAL_MACHINE \Drivers\Builtin\TRUEFFS _DOC1 key. So, I manually created it with the entries as posted, but it didn't work. (yes I did a soft reset after shutting down for 30s or so).

I then proceeded to go to HKEY_LOCAL_MACHINE \Drivers\Builtin\TRUEFFS1 and change the "AutoDPDMode" to 0, and SoftwareWriteProtect to 0. There are 3 such keys: TrueFFS, TrueFFS1 & TrueFFS2. I changed all 3.

Unfortunately, it still didn't work... :(

But Buzz's unlocker prog worked. It didn't before when I was using the official Dopod ROM.

To every body !
I've update my rom to RUU-Prophet-G4-AKU2.2-2.20-2.47.21-Jester-r1.exe. when finished, the extended rom can't use. Change reg not work. So when i lock up at the rom "AKU2.3.1_LvsW_Edition_2006-11-28" i find there're 2 files : extunlock.exe and UnlockExtRom.cab. Run 2 files and finally i can use extended rom with no restrict.
My device is O2 Neo. Hope this usefull for some one :)

Would you please be so kind and upload these two files to the ftp? I'd like to try if it works with the last original QTEK-ROM.
Thank you

hi all.

've been reading some very interesting things in the forum the last few days.
i think you re great.

As far as:
Show extended ROM: [HKEY_LOCAL_MACHINE\System\StorageManager\AutoLoad\ TRUEFFS_DOC1] "Bootphase"=dword:2
[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\ TRUEFFS_DOC1] "MountHidden"=dword:0

Hide extended ROM:
[HKEY_LOCAL_MACHINE\System\StorageManager\AutoLoad\ TRUEFFS_DOC1] "Bootphase"=dword:1
[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\ TRUEFFS_DOC1] "MountHidden"=dword:1

they work ok for me with 2.9.7.24 wwe ROM
2.9.7.8009 extROM
(IPL&SPL 2.09.0001)

after soft reset i can see Extended_ROM2 on my file explorer.
when i check the file properties with resco file explorer all files inside extended_rom folder are read only(which can be changed of course).

so i can easily modify the cab files inside the extended rom along with config.txt entries.

last, changing all files to read only, reverting the registry keys to hide ext_rom
and hard reset.

You can load "AKU2.3.1_LvsW_Edition_2006-11-28.exe", then right click to this file, select "extract to ..." to get these files :) hope this work on your !!

[crazyd]

Great, it works again! Thank you for your help.

[sahaniyas]

could you please to upload just two files ( extunlock.exe and UnlockExtRom.cab.) only, cause my connection is very slow for getting "complete packet rom".thx

[crazyd]

Here you are!

[sahaniyas]

Thaks bro, but still can't edit/delete my ext rom,
one more question, is this ROM can work with Simtolkit App?

[maddude]

Have tried the two files but I still can't install to ExtRom. It says ExtRom2 on my Dopod 818 Pro G3. Currently having more problems with syncing. Ay advise?

HKEY_LOCAL_MACHINE \Drivers\Builtin\TRUEFFS _DOC1
"AutoDPDMode"=Dword:0


I found the following document about the Trueffs file system.
Download the following document http://www.mobilediskonchip.com/NR/rdonlyres/4C09ABD9-C92F-4158-91DC-036403235D01/0/Installing_TrueFFS_for_Win_CE_Rev47.pdf%7CInstalli ng_TrueFFS_for_Win_CE_Rev4.7.pdf

The AutoDPDMode parameter is described on page 12 as:
“AutoDPDMode”: This option enables Auto Deep Power-Down mode, which reduces the
average power consumption of DiskOnChip. Auto mode puts DiskOnChip in Deep Power-Down
mode automatically after each driver command, and takes DiskOnChip out of Deep
Power-Down mode automatically when the driver is called again. Using this mode disables the
option of booting from DiskOnChip via software reset, as the IPL cannot be accessed from Deep
Power-Down mode. In order to boot from a DiskOnChip device in Deep Power-Down mode, a
hardware reset or powering off is required. This registry entry has no effect on DiskOnChip
devices that do not support Deep Power-Down mode.

Looks to me that AutoDPDMode has nothing to do with the write protection of the Extended ROM...
