Also figure this....

When something is designed (hardware), they designate it REV. A on the PCB and design software for that particular hardware for it to run correctly. They produce the first batch, say 100,000 and ship it. But while in manufacturing, they say, if we do this change (software and hardware) we can cut manufacturing costs by 5%. So, the next batch they produce will be designated REV. B on the PCB. It might be a slight change but a change that, you the consumer, will never know.

HTC designes a base model phone for the carriers and each are different. The carriers come up with software and hardware changes they want to make it exclusive and HTC has to accomodate. So HTC slaps on winblows 6.1, the carriers software, and HTC's software and tweak it in winblows and such for each individual carrier's phone to make it run correctly with all hardware and software together by nature. So Sprints TP is NOT manufactured exactly like AT&T's even though they might have the same hardware and similar features in software.

With that said....HTC rolls out REV. A of say, Sprint's TP, AT&T's TP, etc., and they extract the rom from each and cook a new one. People flash it and HEY!!! they work great!! But HTC in the next batch, rolls out REV. B (exactly the the same to you and I but different say, they decided to drop the mA's for the keyboard from 7 to 5) and made the correct hardware and software changes for this to happen. So Joe buys a new TP today (it has REV, B pcb) and flashes a new rom on it (rom extracted from a REV. A TP). Since the new TP's original changed code tells it to draw only 5 mA's, the new rom he flashed tell's it to draw 7 mA's. Since it was an actual change in hardware (and software), what do you think is going to happen? Over a period of time, it's going to say I had enough and quit working. The same goes for all the hardware on the phone including screen, buttons, etc.

There are ALWAYS changes to hardware (especially electronic) throughout the life span of a particular item either for manufacturing cost purposes, performance, or defective parts failing. Your TP might be ever so slightlty different than your friends TP. That is something you will never know unless you have the technical documents in hand of the changes made. So what 1 rom might work great on your friends TP might blow up the screen on yours.

These are soley my views and thoughts and not anyone elses.The numbers I used were for reference only and in no way accurate. WOOHOO, I love you guys!!
