Urgent: Sprint HTC Hero bootloader repair help

[diginir]

Hi all,

This is my first post in this forum and I look forward to becoming a regular here.

I have an issue with a Sprint HTC Hero CDMA phone which has been possibly bricked.

The phone is rooted, with bootloader S-OFF. I was trying to flash an ENG-SPL through recovery when the battery died.

After that whenever I try to turn on the phone the phone does not boot.

Pressing power key does nothing, pressing power+volume up should take into recovery mode but does nothing, pressing power+volume down should take into fastboot mode but I get three vibrates and nothing else. I have read it seems the three vibrates means it is going into Qualcomm diagnostic mode as the bootloader is S-OFF.

The screen remains turned off. I have tried connecting to PC, running factory ROM through RUU but PC does not recognize phone. ADB does not recognize the device.

As last resort I want to know if this can be repaired through JTAG JRT or similar. I am based in Bangalore and would be very grateful if anyone can help me out. Willing to pay.

Thanks.

Here is the sequence of steps:
1. Bootloader was S-ON.
2. Flashed nand unlock file from here.
3. Bootloader became S-OFF. The HBOOT version remained unchanged.
4. Tried flashing a custom splash screen got ADB error remote not allow.
5. Read that for flashing custom splash screen there should be ENG-SPL
(version numbers were given in a video on unlockr.com).
6. Tried to flash Darch's ENG-SPL from here.
Got the icon of arrow out of box. Then the screen died. I presume the
battery died but not sure.

Current status:
1. Power does nothing.
2. Power + volume down does nothing.
3. Power + volume up three vibrates (plus if phone is on charge then the LED
turns off, battery pull and reconnecting to charger LED turns on though).
4. Power + menu five vibrates (plus green LED blinks)
5. Power + home does nothing.
6. Battery LED works i.e. remains red then changes to green.
7. Screen does not turn on.
8. RUU does not work as PC does not detect phone.
9. ADB devices does not detect the phone.

Please suggest if this can be repaired using JTAG.

Please respond urgently.
