Can you upgrade flash rom to 256?
Does anyone know if you can upgrade the 128 megs of flash ROM to 256megs or even anything above the stock 128? I know on some pocket pc's you can but just have to do some soldering. Has anyone heard of it being done or even have the instructions to do it? I would love to give it a shot if there were some directions.
Thanks for the help, Jeremy |

I am looking into this myself but have really hit a dead end. Now don't quote me on this but this is how I understand it. With this device as well as most htc devices the ram is actually on disk on chip from mSystems. The disk on chip is basically similar to a processor in that it uses a die or multiple dies on a micro pcb. This was chosen because of its ability to do XIP or execute in place processes.This poses 3 major problems. 1)The availability of a replacement or donor chip just isn't feasable or cost effective. The only place I would be able to get one at this time would be to salvage one from a damged unit where the MoBo of the phone was already defective. 2) Even with my fairly advanced soldering skill the mSystems chip would require at least a complete hot air rework station and the correct stencil for the ball grid array of that mSystems chip. 3) Even if I have all the hardware in place someone (other than myself) would have to modify the software to correctly use the new memory addresses of the new chip.
Now if I am incorrect in any of this information please feel free to let me know, correct, or add to anything I've stated here. I would love to learn as much as I can about this subject as I love to know how and why I cant get away with things.That and I already plan on getting my rework station after the holidays. |
Thanks for the replies. From research I did on other sites they all say the same thing that it can't be done. :(
What kind of station are you getting? I'm looking to get one myself so I can do repairs. I would love any suggestions. thanks Jeremy |
someone in china has successfully upgrade the ram from 64M to 128 by making some changes to the hardware, so i believe it possible to upgrade the Rom size to 256.
