I updated to NoDo without unlocking and was bummed so I did the following:
1. Flash a pre-nodo unbranded rom, you should find one here:

4. Connect to Zune and update to NoDo. Unlock should stay in place, it worked for me! Good luck!
Thank you for your help. This thread is so helpfull.
Im a newb, I have a lot of questions about doing this, please be nice.
I bought HD7 on amazon and its sim unlocked. I had the nodo update, copy paste update installed on my device, before i could developer unlock it with chevron. Im in a great need for tethering so i want the device to be developer unlocked, so i could use some cracks available in the internet.
My first question is, I want to restore my old rom so if any problem occur i could reflash my device with original HTC rom. Is there any way i could do that?
Secondly, if I flash the htc rom with those listed in the thread (with HTC_europe in specific), will this have an effect on the warranty of the product?
Thanks in advance for your reply.
