[G2 and Desire Z Q&A, Help & Troubleshooting] Benaholic:
Alright, so I'm not the greatest with phone tech, however normal computer tech is my thing so I can sorta get the idea of all this. But anyway...

So for ages I've had apps waiting to install updates, but I never get round to doing it. Today, at work, I was bored & decided to go through & install them. It was all going well, until my phone completely crashed whilst browsing Facebook in Opera. Updates were downloading/installing at this time, though as I say, they were all app updates, there were no OS updates or anything. So, I did what I'd normally do if it crashed or anything, I pulled out the battery & tried to turn it back on. Ever since, I now get to the "HTC Quietly Brilliant" screen, after which the phone cuts off, goes black, resets, & the cycle continuously continues until I remove the battery.

I am able to load it up into HBOOT (I think it's called, by holding down Vol Down + Power), with the following info at the top:

With the following options:

If I click on fastboot, it doesn't seem to work, as whilst it flashes through very quickly it says that it checks the SD & then can't find the images or something:

That's as best as I can tell, as it flashes through very quickly & is hard to catch what it says. Anyway, after that, it just returns to the original menu.

If I click onto Recovery, the phone instantly resets, goes to a white HTC screen, & then to a black screen with the phone & a red exclamation mark within a red triangle. I then press Up + Power & get the following text on my screen:

If I restart the phone then, it just goes back to how it was. I would apply an update, but I don't know what update to apply or where to get them. And I've not tried to wipe anything as, well, I'll get onto that.

Now I've looked around various threads, & was only able to find one that was close enough to my exact problem & I saw that he was able to get his phone working, with your help, so I'm hoping you could help me too.

Now, the phone has never been rooted, or had any mods or anything of that kind installed. And, to be honest, I'd rather keep it that way.

I did have some backup apps installed on the phone (which, I think backed up to my SD Card), however I've never done a complete backup of the phone onto my computer. Therefore, I'd rather not have to factory reset my phone. Or atleast, I will, if there's a possible way of backing everything up first? Though, I'd much rather root the phone & keep everything, than keep it never-rooted & have to factory reset it; if that is an option?

I'm really at a loss as to what to do, & would hugely appreciate any & all help you can give me. As I say, this isn't my strongest area, but I can kinda work my way around it. I do have a Blackberry 9800 to use as a spare, however, I'm not sure which is worse: a broken HTC or that.

Oh, some other information that might be useful:

-The phone is British, bought from Phones4U (I think) early last summer & is on the Orange/T-Mobile network, with an Orange sim card.

-I saw on that other thread about using RUU, which I nearly went to go do, until I realised it wiped everything off the phone, so I stopped myself there.

-I can never remember which version of Android means what, but I'm pretty sure we've not had any major updates since I got the phone. There may have an update, but don't think I've had any of the major ones. I'd guess it was Android v. 2.2-ish? or 2.3ish?

That's all I can think of, though am happy to answer any questions you need to ask. Again, I'd be hugely greatful for your help. And sorry for the huge essay, however I wanted to try to give as much detail as possible, so you clearly knew the situation as best as I can describe. Thank you.

Edit: Could this work at all for me?
