[G2 and Desire Z Q&A, Help & Troubleshooting] 6uitarstrings:
Hello everyone. First of all, please bear with me for I am absolutely a newbie here and have a very limited knowledge on android(or any other) os. Not much of a tech savvy so please, go easy on me. I just wanna try the possible solutions you guys could give me and help my sis save hundreds of bucks from acquiring new phone or going to pricey repair shops.

The phone's HTC Desire Z A7272 (unrooted)

So here's the problem: When I try to turn on the phone, it's just stuck on the HTC logo(w/o the quietly brilliant tag below it). Prior that, my sister was just using the fb app when it suddenly froze. She waited for a couple of mins for it to respond, but nothing happens so she pulled out the battery. When she turned it on, it's stuck on a boot loop (HTC logo+quietly brilliant). We tried removing the battery for a while to let it cool before placing it back but still, same thing happens. We even tried booting it after draining the battery and having it fully charged, w/ and w/o the SD card and sim, but to no avail. Now, it's still stuck on boot loop: HTC logo(w/o quietly brilliant below) then green arrows icon with gray loading bar.

We're able to access the HBoot and here are the details:

On Fastboot, I tried the Reboot and the other options but it just goes on a boot loop.

When I select Recovery, it boots on logo, then there's green arrows icon with gray loading bar below, and then a red triangle with down arrow inside. I read somewhere that it's the stock recovery and from there I could wipe/clear cache, but then when I tried pressing and holding the Up+Down+Power buttons, it says E: couldn't wipe cache/ mount command/recovery - something like that.

When I select Factory Reset, it just loops on the HTC logo and the green arrows icon.

I tried installing HTC sync and connected the phone via USB, but it can't detect the phone(though the PC can, as mass storage and on HBoot it shows 'HBOOT USB PLUG')

My sis downloaded an RUU from HTCDev and copied it to SD Card. She said she was able to Clear/Wipe Cache Partition and data

via bootloader but when it reboots, it's still on the same state.

After looking on some threads with similar issue, some say the ROM may be corrupted so I downloaded stock recovery, stock ROMs (changed the file name to PC10IMG.zip) and copied it to the SD card hoping that it'd reinstall the ROM but still, no effect.

Probably, the ones I've downloaded aren't compatible to the unit, but I don't know how and where to get the exact official ones for the device.

Others are suggesting that I should flash a ROM, but then it requires to root the phone - I don't wanna risk doing it 'cause I'm afraid I might do more damage.

Is there a way to simply reprogram or reformat it(just like what you do on PCs) with fresh/original stock ROM?

Some say that it could be hardware damage (eMMc/Mobo) - hopefully not >_< , but others tell that since we could access the boot loader it's more likely a software issue. :confused:

We also see people mentioning things like Gold card, adb, kernels, etc. but we just get more confused upon reading them(too much tech jargon to take) :(

Are we doing everything wrong? Please let us know.

Most of the solutions we find online are for rooted phones. Hers isn't and just want her phone to get fixed.

Please help. We're really clueless. Do you think this is a hopeless case?

Sorry for this very long post, but I hope I was able to explain the problem well.

Thanks for taking your time in reading this post. Any help would be greatly appreciated.
