Sifus, please help.

I have decided to root my Desire for the first time using unrevoked. I followed the guides on Page 1 on this thread, xda-developers and even watched the video tutorials.

hboot driver done. Then when running unrevoked, I got "Failed to Flash Recovery Image". What to do now?

I'm on Win7. I did everything according to ALL the instructions on multiple sites and video update. HBoot USB driver part done. Just the unrevoked not working . USB Debugging, Charge only, 3rd party enabled.
Google also no answer yet. Still searching.

OK. After 3 hours. Finally decided to uninstall everything and start again...

Now I finally managed to root my Desire.

What I learned...
1. Only use instructions from OFFICIAL xda developer unrevoked thread here.
2. Install and uninstall HTC Sync ONLY (from HTC SEA Support page) because the HTC drivers in this package is needed
3. On the phone > enable USB debugging, PC connection set to "charge only" and untick "Ask Me", enable unknown source app
4. Only use LATEST unrevoked version. Safest to download from OFFICIAL site here
5. Make sure zip files are extracted to folders.

PS. This LYN thread on Page 1 with so many links on rooting guide is not helping. In fact, it confused me more.
PPS. If all else fails, then follow me and delete everything from your PC and start again. Factory reset your phone too, if it makes you feel better.

I'm no expert - just sharing my experience.

It's really annoying that there are so many OUTDATED info out there. Super confusing.

Now that I started going through Custom ROM, I encounter another headache. Not only are the info not updated, they're also all over the place. Not forgetting the same issue of tutorials / guides that are unclear.

So, again - after almost 2 hours, here's what I learned (or at least what I did) about installing Custom ROM. I chose LeeDroid.
1. Check that your phone is really rooted. There should be a Super User app in your app list.
2. Download "ROM Manager" from Android Market. Open the app to Update Recovery files, then partition SD card (select EXT 512mb, Swap 0mb)
3. From here, xda developer guide didn't work. So I followed SmartMoney instructions instead for flashing here. Although his Step #5 and #6 can get a bit confusing.
4. Make sure you use the navigation to SELECT the ROM's zip file that you copied to the SD card's root folder.
5. ALSO make sure you use the navigation to SELECT to reboot once done.
6. Check that you have the Custom ROM installed. Settings > About Phone > Software info

I'm hoping all of you have less headache than me.
