Bootloader erased == JTAG!

[Disillusioned]

Hello Everyone,

I have an i-mate Jamin, G3 I believe with no sign of life. The battery is 100% charged, and I cannot enter bootloader mode.

So I'm trying JTAG to write bootloader back to the phone.

My steps
1. I installed GIVEIO driver and started the service in Windows.
2. I made the JTAG pins using the resistance and connected the device.
3. In Jflash_MM I started start.bat and the phone was detected.

But next, I dunno what to do.

Sometimes I get error messages. Once I was even able to program. But I dunno what file to write to the device, and what is the address for this phone.

If anyone has restored the bootloader, please advice. Also is it possible on this phone or not.

Thnx

[Disillusioned]

Cannot open input file: Flash_ffff_2_32.dat

This program supports flash devices defined by DAT files
contained in the same directory as the executable program.

If the file cannot be opened, there are four possibilities:

1 - The flash device installed is not supported.
2 - The flash device is a licensed product.
3 - The device ID could not be read, resulting in a poorly
constructed filename. The first numeric value in the
filename is the device ID. Verify this value with the
component specification.
4 - The memory bus is not functional. Check all CPLD and FPGA
devices. Make sure that you are using the correct
platform data file.

What is this Flash_0_2_32.dat all about?
