At present there are two types of GENE (P3400) and they are known as NEW GENE & OLD GENE. The OLD GENE is not available now in the market now (i think).

So the main difference between both of them is XIP.

Now come to business....

To upgrade the ROM you need to patch the SPL first.

SPL or Second Program Loader is a part of your phone's firmware. Its responsible for both loading of operating system and it is also used by operating system for some low level tasks. By Default, HTC and Other Manufacturers too, design it in such a way that it does not allows custom ROMs to be flashed in the phone. It does no by checking for the Digital Signature of HTC on roms. So it need to be patched in order to flash custom ROMs.

The SPL patching method is different for OLD & NEW GENE.

To know which GENE you have download this (developed by me) and extract its contents, after extracting execute the file on your PC and follow the instructions there...
