Official 02 rom to official generic rom? - HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting

Ok bascially my hd2 is locked to 02 and has an 02 rom (i.e. Displays "02" when booting) but I want to update it to the generic official rom and not the official 02 rom (long story)
I know my phone will remain locked on 02 but can I go to a generic rom without risk of bricking or is there some sort of security in place that means the phone has to have an 02 or a cooked rom installed?
Thanks

Take a look at this:

Follow the process A,B and C
That will get you to the stock 3.14 ROM.
I used the 2GB microSD card which came with the phone and the CID was the one mentioned in B.O.2 so I was able to do it for free.
When you say "locked on O2" have you tried other sims? I've been with O2 for years and never been locked to them, I often use an orange PAYG sim for Orange Wednesdays and I've used a friend's Voda sim to test something before too.

If your O2 phone is running ROM version 1.48 or 1.72, then you can simply run HSPL2 then flash HTC stock ROM 1.66WWE. 1.66 is the same as 1.72 without the guff.

Well if O2 are anything like T-Mobile UK, then there is their Web'n'Walk software. It doesn't take 3+ months to bring out the 1.72 ROM based on the 1.66 ROM without some major mucking about.

Ah thankfully the O2 ROMs are very clean, and in my experience stable.
Other than the O2 APN settings app, and the O2 splash screen before the horrible orange MS one, that's about it.
