@ahmdhasn:
Now I understand your predicament... If you would notice, I placed an introduction of the utensils about things we need to know when editing a ROM... these are bits and pieces of critical information when doing so, and not a really a step by step guide because each and everyone of us has their own personal preferences in the customization of the ROM. My dismay at first was that, I get a thousand page views from it and not even a single question on what to do UNTIL llbasha came around. And yes, llbasha commented that the wealth of resources available can be very intimidating at first. BUT, one will get the hang of it when you start getting your feet wet. As the saying goes... 'no guts no glory'
So, for your question, this information might be useful for you: All the files we add to the ROM stays in the ROM. If we modify some files like the registry (.hv) and initflashfiles.dat, we can experiment at first by copying the modified files to your PPC. Then perform a semi-hard reset - which means clear registry hive - yes / then format storage - no. If what you want to work on will not work, this means theirs something wrong, we simply just hard reset with format storage - yes | and everything will go back to the original ROM files. This applies even to adding your personal apps. We test it using this method, before we finally burn the ROM, when everything seems to work ok. Oh, by the way, sometimes, we can't copy the files twice... meaning if you have a second modification, you need to format storage again before copying.
Also, another thing we should keep in mind, the files that we got for the ROM is not really intended for the hima, SO, sometimes, files fail to work, and has to be replaced. In fact, bits and pieces of software has been picked up from different ROM versions and ROM devices just to keep it going... As a clue, if something doesn't come out right, we get a similar file from a different ROM that is known to be working...
That's how we solved a couple of non working files (i.e. non functioning excel in virgy rom, the button lock page in most AKU3.5 ROMs, etc...) Whether we like it or not, there are some things that will not really function in the WM5 environment... (i.e. backpack accessories) Things like these require programming skills and adequate knowledge in the device to do some modifications of the original file to work in our himas OR worst write a new WM5 device driver... This is where people like buzz, mamaich, etc. come in, BUT, because everyone here does it in their spare time, we'll have to be patient...
Good Luck! and thanks for your feedback...
