Unlocking the Extended ROM is now possible again on new HTC Hermes ROMs

Download:
  • Hermes Extended ROM Unlocker & Unhider v3
    Works in ALL ROM versions, but you need to CID Unlock your Hermes first if you want to UNLOCK the Extended ROM (you don't need to CID Unlock if you just want to unhide the ExtROM):
    HERMES_MountALLExtROM.cab

Instructions:
  1. CID-Unlock your Hermes (NOTE: This step is only needed if you are using a NEW rom and want to UNLOCK the Extended ROM)
  2. Install cab file on your device
  3. Power off the device for 10 seconds
  4. soft reset with stylus

Before asking questions:
Read the wiki:
Notes:
  • All cab files you put on the ExtROM need to be signed with a valid certificate to install after a hard reset (there's no known way to circunvent that yet).
  • You can use the ExtROM folder as extra storage space (~10Mb).

Enjoy!

Is this unlocker easily reversible (translation: how does one lock again)?

pof let me get this right, it is now possible to unlock the extended rom with bootloader 1.06 like the RUU_HER_Cingular_1.34.502.1_1.16.00.00_wwe_cws_shi p.exe

Thanks guys for your comments and beta-testing

As you may have seen I splited the old sticky thread about ExtROM unlocking and made this new one, to avoid confussion on new people.

Now to your questions:

It's just a registry hack (see the cab file is just 4kb), very easy to hide/lock again. I will post instructions on the wiki later, so it can be integrated on the next version of fit4cat hermes tweaker too

Yes it is posible to unlock the ExtROM on this ROM too, bootloader has nothing to do here... (this is an ExtROM unlocker, not a CID / SIM unlocker).

I ran the v2 unlocker on my 8525 and can see the Extended ROM, but whenever I try to install programs to Extended ROM I get an error that they could not be installed.

Am I doing something wrong? I've done this a bunch on my Apache without any issues.

URPREY: I installed some programs on mine and it's working fine, i'm running cingular's 1.31 rom now, haven't tried with 1.34.

Try running the v2 CAB file again, make sure you power off the device for a while for the registry settings to keep, and then soft reset it, see if it works this time.

I did do that pof

I doublechecked the registry keys, and they correspond to the LOCKED description in the wiki:

LOCKED:
HKEY_LOCAL_MACHINE\SOFTWARE\Drivers\MSYSEXT
"Background"=0x0 (0)
"Foreground"=0x0 (0)

When I looked at setup.xml in the cab file, it appears that those are the values specified? Is that the correct value or should they be changed to something different to unlock?

Yes, this is how it should be... the registry keys on the wiki are still not updated, the info there is from the old cab. Can you try to install the old cab first, and then the new one? tell me if it works this way

Unhappy
Hi pof,

I had used this on RUU_HER_ChungHwa_1.25.751.4_1.07.03.10_CHT_SHIP, but it seems doesn't work, it can unhidden the Extended ROM, but can't unlock.
