Hi. I'm the owner of an Orange branded Desire and, as with most other people in my situation, I'm getting a bit fed up with being faffed around by Orange regarding the Froyo update, if only because I really want some of the niggling bugs fixed rather than big new features. I've printed out a few guides on debranding, and bought a microSD to SD adapter, and I'm highly computer literate (as soon as I buy a new PC I immediately remove all the partitions and rebuild it from scratch)... but I've never debranded a phone before. All of the guides I've seen seem to be a bit lacking, and tell you some things but not others. So, before I take the plunge and potentially brick my phone I have a few questions, which may sound totally noob but I'd really appreciate some answers. Goldcards. OK, so I plan to take the card which came with my Desire and turn that into a Goldcard. I've got the app to do it, and I know about getting the image etc. All of the guides mention that if you plan to use your operator-supplied card as your Goldcard you should save the existing contents to a folder on your computer first. So here's the first "sorry for sounding thick" question. Once the Goldcard is created do I just copy everything back onto the Goldcard and it will still be fine? Are there any conflicting folder names etc. which may cause problems? SIM locks. Some of the guides mention that if you debrand with your SIM card still inserted it will be locked and you'll have to buy a code to unlock it, but if you take the SIM out and debrand it will be fine. Question: What about future updates? Every time HTC release an update do we have to take the SIM out again before downloading & installing otherwise it will get locked? Backups. Almost all of the guides tell you to install e.g. MyBackup (which I have done) and back up all your apps & data to the SD card (again, I've done this). None of the guides I've seen then tell you what to do after debranding - instead they stop after the new ROM is installed and don't go any further. Question: I take it we then have to reinstall e.g. MyBackup (question: from the Market again?) and restore everything? If we reinstall the apps from the SD card will they still appear as downloads, and therefore show future updates, in the Market? Settings. I know that Orange apply numerous settings to the phone in order to make it work on their network - message centre addresses, mobile internet servers etc. Question: Are these reapplied when we restore the backup mentioned in q3 above? Apologies if I sound really thick here, but with something as potentially risky as debranding I'm surprised nobody seems to have put together a completely idiot-proof guide, along the lines of 1. Download this file from here. 2. Double-click the .exe file. 3. Click Next... taking it right to the point the phone will work again and be able to make calls, send texts, connect to wireless and mobile internet... etc. This uncertainty is why I'm currently very keen but simultaneously reluctant to debrand. Any advice gratefully received. Thanks.
