Default New ROM version 1.11.405.4 (ENG) for HTC Excalibur

A new test ROM for the HTC Excalibur is available on xda-developers!

Rom Version: 1.11.405.4 (English)
Radio Version:
Bootloader: 1.11.0000 (Sep 12 2006 at 13:08:40)

You can find the ROM on XDA-Developers FTP:

RUU_Excalibur_HTC_WWE_1.11.405.4_4.1.13.28_02.63.9 0_Test.exe

For the curious out there, the ROM is shipped in NBH format so you can extract it if you want to look at the ROM components, the bootloader (SPL.nb 512K size!) has a lot of debugging information enabled as this is a Test release ROM.
EDIT: For those people having problem in updating to new Excalibur ROM due to Invalid Model ID error, that is due to bootloader version on Dash. You need to flash this bootloader first and then flash the Excalibur ROM. Also, this bootloader CAN be used for flashing new ROMs on pre-production Excalibur devices.

RUU_Excalibur_SPL-1.11_UpgradeOnly.exe contains bootloader version 1.11.0000 (Sep 26 2006 at 20:19:20).
PS: I don't own an Excalibur and I can't test it so I don't know what's on this ROM, if you try it please post details about it.

Pof, sorry, I would like to test but... I can't suggest. If someone can upload the HTC original ROM I will test the TEST rom :)

My ExCaliber is running a earlier, but, very stable ROM.

Radio Version

Be great to try something new ... I'll let you know how it works out and when I get the ExCaliber commercial ROM I'll throw it up here for you.

Hey guys,

I just got my HTC S620 from Expansys TODAY, and you'll be surprised to hear that it is running the ROM posted in the first post of this message:

ROM: 1.11.405.4

The phone is very stable and fast, with no issues at all. Very pleased with the OS (previous Windows phone was a slow Tmobile Vario). Plus the form-factor is superb.... :)

I'll let you know if I run into any bugs. So far though (1/2 day of use), no issues....

What is this new ROM supposed to fix anyway?

How good is this ROM? Is just the basic S620 SW with some engineer plugins? How easy is it to upgrade the ROM? Ive never tinkered with upgrading on windows mobile phones.
