[Touch Diamond2, Pure ROM Development] elmalote:
Here goes,

I gave it a go and started cooking.

Please bear with me, its my first ROM, but should be good and stable.

Requirements: HardSPL

Safest way to flash is using SD Card:

THE WAY TO FLASH A ROM USING THE SC-CARD (also tnhx to jiwei1984):

1. Make sure you have HARDSPL installed (soon...).

2. Format the sd-card to FAT32 (if not already).

3. Copy the ROM (.nbh) to the root of the sd-card and rename it to topaimg.nbh.

4. Bring the device into bootloader: press and hold Volume-down button and then Power button.

5. Confirm the question to upgrade.

6. Wait for upgrade to finish and enjoy...
