[HTC Incredible S] Kimmoth:
Thanks for that :)

...But now I'm really stuck :eek:

I unlocked the bootloader and installed Clockworkmod Recovery okay, installed SU and backed up my stock ROM no worries, but then I ran into a snag when I ran Nonverbose's script:

version-main: 2.00.000.0

If the version-main returns 2.00.000.0 you should be
able to run the RUU downgrade. If it does not, answer n to the
unlocked bootloader prompt no matter what.

Do you have an unlocked bootloader from htcdev.com?

So the bootloader was relocked.

The VERSION will be changed to: 2.00.000.0 puzzled me because that was already my HBOOT version, but the FAILED (status read failed (Too many links)) alarmed me, and I guess I should have stopped there to figure out the issue...

But instead I figured there was a chance it was just a minor glitch that wouldn't affect me and pressed on with the RUU downgrade which seemed to work because my HBOOT version is now 1.13.0000, but now although the phone boots normally, my recovery is broken (just showing the red triangle ! icon)...

So I try to re-flash CWM...

OKAY [ 1.147s]
writing 'recovery'...

FAILED (remote: signature verify fail)
finished. total time: 1.766s

:crying:

Dammit! What can I do now? I've already checked the unknown sources/debugging checkboxes in settings again, if that makes any difference.

Note: at some point in the process my lockscreen changed and I had to go through the initial setup wizard again; not sure if that says anything, but I wasn't expecting my ROM to be affected yet...

Is there an update.zip recovery I can flash?

Never mind, I got thrown by the fact my ROM glitched right up on first load, so I freaked out and went to re-flash my stock ROM without realising I wasn't meant to have a working recovery at this stage of the process...

After my phone worked again and I ran out of wrong trees to bark up I had another look at the guide and realised I should just continue :laugh:

...I think the guide could prevent a lot of such panics by contextualising each step more for noobs (no matter how many phones I've unlocked, I'm a noob every time because it's so many months between new phones, and there are just too many layers in the process to remember)...
