[Acer Iconia A500] Psychlone:
Thanks guys, I really do appreciate the help, but I'm still having serious issues reverting back to HC.

I feel like an idiot, but I have to say that even though it seems so, I'm actually the owner of a computer repair business, have 28 years experience in PC/Mac repair, and have rooted and modded every android device I've owned (including some for friends as well) - all the way back to the very beginning with the D1. This, however, has thrown me for a loop. NOTHING with this A500 has been this complicated! Everything up to this point has literally been stupid-proof and I've actually been quite impressed at just how easy modding is on the A500...

Anyway...

Here's what's going on and what I've tried today:

I've tried unsuccessfully several times to get ANYTHING working on my laptop, but to no avail. Same story as last night, no progress whatsoever - however, I did note that with CWM 134, I was able to restore an earlier version of ICS 4.03 (Flexreaper R10 I believe) - but it wasn't easy... I ended up restoring the main image and then using parts and pieces (using Advanced Restore) from other saves to finally even get it to boot.

This clearly wasn't getting me anywhere, so I moved the entire operation to another computer - my main rig (also a Win7 x64 - in fact, I don't own a computer that's not Win7 x64)

Now I've got USB driver issues! I can't even install the standard USB drivers from Acer's website because the installer errors out saying that there's no version of Acer Iconia 3G Driver Install is installed. wtF? That's what I'm TRYING to do!

I did get a different USB driver installed - the USB Driver_Acer_1.06.1500_A30H_A500, but nothing wants to use it and Blackthund3r's APX Flash Util won't see it, AfterOTA won't use it, and it's basically useless anyway. AND I can't install the Acer_1.00.0524_A30H_A31H_A32H_A500_A501 drivers no matter if I've got any others installed or not.

In my device mangler, there is no device with an exclamation, and in fact, sees my Acer Iconia A500 under USB Serial Bus Controllers as "Acer Picasso USB Boot-Recovery Driver", only when it's plugged in. NO other instance shows up at all.

I'm actually at the point of trying to follow through with the EUU (dibb_nz's "last resort"), but vache's website is down and I can't download anything for it. In fact, there's nothing from that guide that has a valid link...

So now where do I go? I understand IT really well, so you don't need to talk to me like a complete noob, but dang if I can't figure this one out!

If I can get valid links to all the downloads from the link above, I'd be more than happy to give it a go and see if that works, but I can't piece together all those things from random places. If either of you (or anyone else for that matter) has valid links for everything needed to follow the EUU guide, I'd be very grateful!

Any other advice would certainly be appreciated as well! I don't have to use either of these computers, but as mentioned, ALL of my computers have Windows 7 x64 on them. I suppose I could try one of my customer's computers for all this, but that's not morally right and probably something that I would prefer not to explore.

I feel as if I could get the USB drivers installed properly on EITHER machine, that I'd likely be in good shape. I think that's what my problem actually is on the laptop as well, even though they're all installed and shows as installed until I boot into any recovery - then I get the MTP Device Driver Fail. There's likely other Acer driver issues there though, since Blackthund3r's utils don't follow through for anything... everything just hangs. AfterOTA just hangs.

Advice please?

And thanks again for your knowledge!
