I've just implemented an Excalibur USPL which allows you to flash any Excalibur ROM updates, i.e. you can flash any *official* ROM even if your phone's model and vendor ID doesn't match. It's confirmed that you can also flash cooked ROMs
This SPL is based on original Excalibur 1.11 SPL but includes 3 patches:
1) g_cKeyCardSecurityLevel = 0 (set 32)
2) Does not check Model & Vendor ID
3) Does not check signature*
(*) code must be formally signed i.e. contain properly-formatted signatures on the right places, however no checking is performed against them.
This means you can flash ANY ROM to your Excalibur after running USPL on it, no need to pay for CID unlock anymore!
The USPL will *not* help you to SIM unlock your device. You still have to pay for that.
The USPL runs in RAM and is *not* flashed to your device, so there is no risk there. Once it runs you can run any official Excalibur ROM update utility.
The USPL does *not* permanently CID unlock your phone, like the CID unlocker from imei-check or so.
After you flashed a ROM your phone is again CID locked. Each time you wonna flash a ROM with a different model and/or vendor ID (different from your phone) or a cooked ROM, you must run the USPL again and then flash the ROM.
It's beta and untested and the risk is entirely yours !! Don't blame me if you brick your phone
The main reason for implementing this USPL is to support the poor guys who bricked their wifi. See this thread.
But those who want to flash a device where wifi works don't need to be afraid that wifi fails after the upgrade.
You can now also flash the USPL allowing you to flash any unsigned (cooked ROM or ROM module, e.g. radio or OS) or signed ROM with any model/vendor ID. The USPL substitutes your SPL until you perform a full ROM update. Consider it as an extra insurance in case something goes wrong with flashing cooked ROMs or any other ROM update !
