Free HTC Hermes SIM & CID Unlocker *New* version v3a
This is a patched radio ROM that can be used to remove the Operator SIM lock and CID lock from HTC Hermes based telephones. This new version also includes HardSPL patched bootloader to show always as SuperCID and allow to flash unsigned code.
It can be used in
all HTC Hermes devices, no matter which bootloader version the device is running.

History: v3a [03-04-2007] - New RUU will make sure HardSPL-1.40 is installed before flashing the radio
Now the unlocking process is faster & safer
Fixed bug where IPL was downgraded to 1.00
v3 [11-02-2007] - Herm_Unlock_v3.exe now allows you to select SIM / CID unlock separately
Thanks to SSPL it can be used in all bootloader versions
Patched radio is now provided in NBH format
It keeps the current bootloader on phone (does not downgrade SPL).
v2a [14-11-2006] - bugfix release, thanks to all who reported the problems!
(hopefully) fixed bug where unlock code has to be entered manually
(hopefully) fixed bug where SuperCID was not kept after rom upgrades in some cases
v2 [12-11-2006] - updated to patched radio 1.16
unlocking software provided (HERM_Unlock_v2.exe): thanks buzz for the source of UNI_Unlock_v1
SuperCID is now kept after rom upgrades
v1 [05-11-2006] - patched radio 1.13
unlock manually

FREQUENTLY ASKED QUESTIONS
Q: Will this void my warranty? A: If you select the option to "CID unlock" most probably yes. Don't select it if you just want to remove the SIM-Lock, it will be CID unlocked anyway by HardSPL but will keep your original CID if you flash any other SPL on it.
Q: After unlocking my phone my Radio and SPL versions are downgraded. Can I upgrade them? A: Yes, you can upgrade to a newer radio and newer SPL/HardSPL version. The phone will not be locked again.
Q: Will this work on Post Dec-2nd SoftBank X01HT phones? A: Hopefully yes, but your OS ROM includes software SIMLock protection (the annoying USIM screen), you can flash a non-softbank OS rom after unlocking it or read the thread for other options if you want to keep the SoftBank ROM.
Q: Will this work on Post April (white) SoftBank X01HT phones?
Yes if you have not let the SoftBank ExtROM install, otherwise your radio bootloader has been upgraded to 0182 and it is not possible to flash a radio or remove the SIMLock.
Q: Will this work if my bootloader version is SPL-1.09? A: Yes.
Q: Will this downgrade my bootloader to 1.04? A: No, it will upgrade it to Hard-SPL 1.40 which is better. You can use
Custom RUU to flash any ROM on it.
Q: Will this work if my radio bootloader is HTC_BOOT 0108? A: Yes.
Q: Will it downgrade HTC_BOOT 0108 to 0107? A: No, if you have 0108 it will keep 0108.
Q: Do I need to run the new version if I already used the older version previously? A: No, your phone is already unlocked, no need to run unlocker again.
Q: After finishing the process it still asks for unlock code, what should I do? A: Make sure you have radio version 1.16 and run Herm_Unlock_v3.exe on your phone and select unlock option. If entering any unlock code fails, please repeat the unlocking process again (you did something wrong the first time).
