[G2 and Desire Z Q&A, Help & Troubleshooting] Ceristimo1:
Hi everybody,

After having tried to sort this mess out myself for days now, I feel that I am all out of options. I hate to have to bother you with this problem, because I'm sure I'm not the first one that has a fried Desire Z, but I really hope somebody can help me out. It seems that none of the solutions I have seen to revive this phone work for me.

Okay, so after having made that apology for wasting your time beforehand, let's see if somebody has any idea how to make my phones heart beating again.:)

The phone in question is the HTC Desire Z. It's not rooted and it's S-On. Honestly, before my phone died I did not even know what H-boot, fastboot, rooting or S-On meant. I had never heard of a bootloader before, but I've tried to educate myself on the matter as good as I could.

Anyway, it died after I tried to install a bunch of Market updates. Google taught me that that is how the phone dies for most people.

During the Market updates the phone froze, and I pulled the battery. After inserting the battery again, the phone got stuck in a boot loop. Pulling the battery yet again fixed that issue, and the phone booted fine.

And that's when I got stupid and decided to run the Market updates again. Long story short: Phone froze again, I pulled the battery, and now the phone is stuck displaying the HTC logo (without the "'Quietly Brilliant" slogan underneath) on a white background.

First thing I did was calling HTC support, just to find out the phone is not under warranty anymore. So I'll have to mess with it myself, hopefully with you guys trying to hold my hand during the process...

The phone will still boot in H-boot.

If I select FASTBOOT I can still communicate with the darn thing when it's hooked up to my computer's USB-port. So at least that part still works. I installed the Android SDK on my computer so I have fastboot on it.

Selecting RECOVERY will make the phone reboot. After displaying the HTC-logo for about 5-10 seconds it will display a fancy looking icon of a phone with a green arrow for a couple of seconds (I can try and make a photo of it if anyone wants to see it?), and after that the screen goes dark. Then it will vibrate 7 times, and that's it.

Selecting FACTORY RESET just instantly freezes the phone in H-boot.

I did find a couple of topics on this forum that looked helpful, but I just cannot figure out how to make it all work.

Here is one that looked very promising:

"[GUIDE] Booting an Android System when only Recovery is at your disposal"

However, my problem is that Recovery is not at my disposal.

And that is where I got stuck. What is also not very helpful is that my phone is not rooted and it's S-on, and I can't find out how to root a unresponsive phone with which I only have FASTBOOT access. I don't even know if that is possible at all.

So yeah, again:

A completely stock Desire S with a fried eMMC chip and no working recovery in H-boot...Any ideas, or am I just really, really screwed? With my own research I've come to conclude the latter, but I so sincerely hope someone can prove me wrong...

EDIT:

For what it's worth, here is the H-boot information
