History

There are two ROM’s made by XBmod and Yuki (within a few days of releasing the ROM Yuki retired from XDA, may they RIP or be resurrected in the future) XBmod continues to build and offer solutions. But understand that you are indebted to them and others – for providing the ROM.

Concept

To build a WP7 ROM that can be updated by Zune when MS release updates and Also so that Dev’s or anyone can develop custom CAB’s to be sent to the device without the need to reflash or mess with the system…….

The ROM

Both are Unbranded i.e. Vanilla flavor i.e. No carrier branding and you have Root access.

There are two differences between V1 and V2 ROM’s

1. V1 - HD2_Updatable_XBmod_Yuki_v1

a. Radio: 5.69.09.05a_22.50.50.21u

b. was an attempt to try and get he Sdcard working for other things but it failed, V1 remains for future development only

(Feedback from those testing V1 was that the Radio caused extreme battery drainage and the SD card created more issue than good, so V2 was born. V1 is left for others to play and possibly future development, to see if they can eventually get Dual boot to work – but it may never occur and quite frankly this ROM is so Stable & Pure and running on the best device ever, that you don’t need another OS)

2. V2 - HD2_Updatable_XBmod_Yuki_v2_native

a.	Radio: 5.51T.09.29a_22.32.50.10U

b.	Formats the SD card like a native WP7 device

(Feedback about battery performance has been for most, positive with a few exceptions will attempt to build country table in Appendix)

Common Questions

Q. Which ROM should I use?

A. Use the V2 ROM for obvious reasons.

Note: When you flash you will LOSE ALL DATA from your SD card, so if you need it - back it up! Also some SD cards present issues so be warned not all work…..

Make sure it’s a SD card that works and is supported, otherwise you could face frequent reboots / freezes / restarts / loops. SandDisk seems to be the best so far try to use class 4, you can use, 2GB, 4GB, 8GB, 16GB and even 32GB

Q. Can I Dual boot and Run Android?

A. Yes. XBmod has released a CAB that can be used to unlock the SDCard for Dual boot.

Q. I’ve installed V1 should I move to V2?

A. that’s up to you, but the general consensus is Yes move to V2

Q. I’m on V1 do I need to Start right from the beginning – re-run the whole Process?

A. Update oriignally yes, but we have a report that someone has gone straight from V1 to V2 without going back to stock rom (WM6.5) by simply flashing V2 on top of V1. No reported problems. So, it's up to you...

Q. Do I need to change the HTC HD2 name in about to HD7

A. No the HTC HD2 is just afriendly name, it wont and can't cause any problems anywhere. The phone is registred as an HTC Schubert (HD7)

RADIO:There are two Radios:

The first which you install during the initial set-up and another which is Baked into the ROM. Some folk who want to play and experiment will want to change the Radio in the ROM – you can do this and more about that in the Appendix:

UPDATEL: XBmod is working on a CAB to change the Radio in the ROM, thus in the future you will be able to send the CAB and change the Radio.
