HIDE / SHOW ExtROM on HTC TyTN (Registry Tweak)

[ghl10000]

Hide/Show Hidden ROM (at least works on my TyTN - German ROM)

SHOWN:
[HKEY_LOCAL_MACHINE\System\StorageManager\AutoLoad\ EXT_FLASHDRV] "Bootphase"=dword:00000002
[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\ EXT_FLASHDRV] "MountHidden"=dword:00000000

HIDDEN:
[HKEY_LOCAL_MACHINE\System\StorageManager\AutoLoad\ EXT_FLASHDRV] "Bootphase"=dword:00000001
[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\ EXT_FLASHDRV] "MountHidden"=dword:00000001

[pof]

For me this was the default:

[HKEY_LOCAL_MACHINE\System\StorageManager\AutoLoad\ EXT_FLASHDRV] "Bootphase"=dword:00000002

So, I only had to change this from 1 to 0:

[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\ EXT_FLASHDRV] "MountHidden"=dword:00000000

Now I can see the extended rom, my device is an HTC TyTN WWE, I will post the ExtROM to FTP in a while.

I also have updated the wiki page with your hack:

Thanks!

GREAT !

Now we still need 2 very important Registry Hacks (or missing links to get them work):

1. A hack for presenting a differentiation between GPRS/EDGE and UMTS/HSDPA

2. A hack for invoking the EngineeringTest Mode

I've been unable so far to get that working on the Hermes platform. Keep trying.

Thank you. :)

I finished uploading my ExtROM, I also created a wiki page with the contents of all the available Extended ROMs on FTP so far:

http://wiki.xda-developers.com/index.php?pagename=Hermes_ExtendedRoms

If anyone has a different version not listed, please do the following:

1) Unhide it
2) Zip it
3) Upload it
4) Update the wiki page

Thanks!

Heh, youre busy one. :)

I added a registry tweak to change the titlebar clock to an annalog one, if someone is interested.

Hopefully we can keep the wiki growing and useful. :)

My default setup was also:

[HKEY_LOCAL_MACHINE\System\StorageManager\AutoLoad\ EXT_FLASHDRV] "Bootphase"=dword:00000002

[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\ EXT_FLASHDRV] "MountHidden"=dword:00000001

So I just changed to:

[HKEY_LOCAL_MACHINE\System\StorageManager\Profiles\ EXT_FLASHDRV] "MountHidden"=dword:00000000

and did a soft reset. The extended rom then appeared but it was still write protected. How do I get rid of the write protection?

Use the cab file in the wiki, it unlocks and unhides ExtROM.

[Rougenator]

After using the cab fille and/or making the tweaks myself, and the are the same as described as above, the result is that I can see the ext. rom, but it is still write protected. I can't delete any file or write a file to the ext. rom. I've got a Tytn WWE. What is the problem, or better: what is the solution???

[pof]

Should be wrtitable using this cab:

ftp://xda:xda@ftp.xda-developers.com/Hermes/Tools_and_Programs/HERMES_MountExtROM.CAB

If it's not, then try to hard reset and then use the cab without messing with registry keys before.

[LuckyBos]

I have tried all the methods in the wiki and also all the reg. edit trick but I still can't see my extended ROM. When I run the cab to Mount Extended ROM it crashes my TyTN. Locks it up befor making it to the windows screen. Does anyone have any ideas how to fix this or tell me where to look? I was going to mess around with bootloader but I am not that computer savy.

[pof]

hard reset and install the unhider&unlcoker cab file. it should work after hard reset.

[rcyh]

Have tried to Hard Reset my Taiwanese CHT9000 and only apply the HERMES_MountExtROM.CAB tweak, now can see the Extend ROM, but still cannot "unprotect" the ROM. Cannot make it writable. Any other methods? Like modifying the registry? Thanks a lot in advance!!

On my Vario 2, when I'm using 3G (and therefore, HSDPA) the [3G] icon is shown in the top bar (and when it connects a small connecting icon with the moving arrows and 3G in it is diplayed, next to the square 3G indicator) - when it drops back to GPRS, it just changes to [G].


Does yours not do this?

Unsure whether it works myself, as I've not tried it yet, but I'd put (a small amount of) money on it that it works :D

[rcyh]

Hi Chris, Thanks for your reply!!

Unfortunately, my device is still un-protectable after following the whole process. And the registry settings I have checked are exactly the same as the described. The Extended_ROM directory is still write-protected. Couldn't add or delete files in it.

Maybe I am the unlucky one that couldn't change the extended ROM at all...

Since the digital signature security autentification for CABs in ExtROM is on by default, putting in any CAB file that is either not digitally signed, or loses its authenticity because it was modified will not be installed during the Customization phase after a hard reset.
Any ideas how to solve this problen on TyTN?
There was the soluton for the Universal devices wiht the Default_Signed_DisabledSecurity.CAB. This CAB has the right signature for Universal, but it dosn’t work on TyTN.

[christopherwoods]

From this MSDN discussion about Windows Mobile 5 code signing (http://blogs.msdn.com/windowsmobile/archive/2005/12/17/security_model_faq.aspx),

"Looks like you won't have to sign the cab if wceload.exe isn't used to install it. Although if it is used to install the cab file you will need to sign it."

http://blogs.msdn.com/windowsmobile/archive/2005/12/17/security_model_faq.aspx#506035


A possible gap? If someone could come up with a third party CAB installer that could be used during customisation, maybe it could bypass the official CAB installation procedure (and therefore the signed certificate verification) entirely? Just a thought.

[sykt]

For Universal this problem i think was decided here (http://forum.xda-developers.com/viewtopic.php?t=33638&postdays=0&postorder=asc&start=150) with the help of Default_Signed_DisableSecurity.CAB. But this CAB not work on my TyTN. I think it because of wrong digital sign.

My DOPOD 838Pro with the latest Cingular ROM displays U and G when available. Anyone have a hack that displays all four G,E,U, and H?

Any Help?
Thanks

Hi.
First of all...sorry for my poor english :)
I have a problem with my
HTC P3600 (Trinity)(RUU_Trinity_HTC_ITA_1.23.408.1_6275_1.38 .00.11_108 _Test upgraded)
about the UNLOCK process of the extended rom.
With HTweakC i've made it readable so,now,i'm able to view the content.
After this i've tried with registry hacks to make it writable with no success.
I used also HERMES_..rom.cab but the ext_rom itsn't writable yet.
If someone knows a solution or a simple advice i'll be glad.
Have a nice day.

[madhero]

hi guys...
i've got the HTweakC that unhides and unlocks the Ext ROM. it couples with some other hacks... though i don't know if i'm able to post it here cos it's... umm... cracked...
so let me know... and i'll post if i'm allowed...
adios.

[papakeithjenkins]

Since the digital signature security autentification for CABs in ExtROM is on by default, putting in any CAB file that is either not digitally signed, or loses its authenticity because it was modified will not be installed . . .

Okay, my problem is apparently one of signing - I install this terrif prog and get this UGLY message about unsigned this and missing that - but I don't want it saying that, I want it working.

This program is the Koolest Caller ID program ever on a PDA/Phone, unfortunately, it is out of date. It was made for WM 2003 but it works on all versions of WM 2002 and 2003, but not on WM5 or 6, and I use 6. The truly kewl part is that it allows us to use animated .gif files as the images identifying the caller. I have attached a couple of the ID files below - one I found, one I made (Lingerie One) along with the program in my favorite version.

I hope someone can make this thing work on WM5 and WM6 as I really do like it and I am sure that others will too.

TIA,

[TeWeE]

So, no one is able to tell how to make the ext_rom writeable? - I used the crack just after I flashed it, and it's unhidden, but not writeable.

[PhilippeF]

Same problem with my M3100 from Orange France.
Since I installed new ROM AKU 3.3, I can mount Ext_ROM but I cannot unprotect it. It worked with previous ROM AKU 2.3.
:confused:
