[G2 and Desire Z General] sonny88:
Hi guys,

I've searched all over the internet and offcourse XDA but I don't know what to do anymore.

Somehow my HTC Desire Z frooze a few weeks back, and after pulling the battery the phone was stuck at the HTC screen. I tried factory reset,recovery etc but that all didn't work. The phone just freezes.

The phone is NOT rooted, unlocked etc. No apps where installed before the phone froze.

Some information:

1. Downloaded this RUU which i'm sure it's correct.

RUU_Vision_Gingerbread_S_HTC_WWE_2.42.405.2_Radio_12.56.60.25_26.10.04.03_M_release_199043_signed

2. Drivers are installed and recognized (fastboot and bootloader) on Windows 7 x64 and Windows XP Home Edition. (have 2 PC's just in case)

3. I have installed the latest Android SDK.

4. I have installed HTC Sync. (messed around with drivers from Google and HTC)(believe me I know what i'm doing so it can't be because of the drivers:p)

5. I don't have or need a goldcard.

6. ADB is recognized by Windows but shows

error: device not found

7. Fastboot lists my device as "fastboot devices"

SH0B9RT0**** fastboot

8. When in HBOOT I can manually switch back and forth between fastboot and bootloader, but when selecting "reboot bootloader" from the fastboot menu the phone immediatly freezes again.

9. When the RUU reboots the bootloader the phone freezes.

10. When the RUU says "waiting for bootloader", and I manually power on the phone to HBOOT (seen as "Android Bootloader Interface" by Windows) the phone still isn't recognized.

11. Also tried updating the device list for ADB from the command line "androind update adb" - no result

12. Manually add the device ID "0BB4" to "adb_usb.ini" - still not seen by ADB.

I really believe I tried everything google threw at me. Can my bootloader be corrupted somehow? Any suggestions?:p

--------------------

UPDATE:

I extracted the ROM.zip from the RUU, renamed it to PC10IMG.zip and placed it in the root of my SD card. Booted up the phone in HBOOT and it automaticly started the update process. At this point it is once again stuck at the bootloader.

At this point I think the eMMC chip is dead.
