[Q] Stock ROM doubt - Android Q&A, Help & Troubleshooting

Hello all!
If anybody can help me with simple doubts, I'd appreciate!
1- Stock ROM: an Android stock ROM is model dependent? So if I have an Android phone and want to install the stock version I have to find a ROM compatible or even made for the phone model I have? In case of a non branded phone (those chinese), which model is likely unknown, can I flash to a stock ROM?
2- An application is refusing to download from Market, because it says incompatible device (which is surprising since I thought any app would install, since it's Android). The developers told me that probably I have a moded version of Android system and they don't support it (!). How usually applications does this checking?
As you can see, my question 2 is related to question 1. I'm wondering if I can flash my device to a stock version of Android and get this application downloaded from Market (without blocking because it's considered incompatible).
Anyway I'd like to get answer for two questions independently, if possible
Just an update: I have two phones. One downloads this app without problem and in Market I see Maker=- and Model=P800W. The other one (which says incompatible device) Market=- and Model=-. This might be the problem.
Thanks!

Yes. The stock rom (or any rom) has to be made specifically for your device. If you don't know the model of your device, then find out. If you can't, then do NOT try to flash any rom. Your device will be bricked (if its the wrong rom).
You thought wrong. It doesn't matter that the system is android. It's the hardware and software version which matters. Many applications (like the great 3D games and powerful apps) require an armV7 instruction set processor. So if your device doesn't have this, you really can't do anything about it (legally). Applications check if they are compatible before they are installed. If they "find out" that they are not compatible, they will not install. On the the software side, many applications no longer support the older versions of android which could also cause the incompatibility.

Thank you!
Probably the biggest problem is that, for some reason, Market has no information on Maker and Model.
I just checked the model. It's a T8585. Is there anyway I can update this info on my device (maybe some variable in the system) so it will be correctly listed on Market?
The previous phone had Model listed as P800W and I had no problem to install the application.

Is your device an HTC HD2? Did a search and it's the only device shown. If it is an HD2, then just flash a new rom. That should fix it. There are system properties which can be changed, but changing them may cause your device to bootloop and you'll be in more problems.

It's a chinese one. Not exactly the specs of HTC HD2 (slower processor for example).
But there is a T8585 stamp on the back. If it's not the same processor, why list it as T8585... maybe the mainboard is the same? So a ROM made for HTC HD2 might work?

Post some images of it.

Attached.
My thoughts:
- I think this device should support the app I'm trying to install (including Skype). But, since it's showing "-" as Maker and Model on Market, some applications are blocked or don't work (because they don't validate the phone).
- T8585 means HTC HD2, right? But... some specs are different: slower CPU (mine is 416Mhz), worse camera (mine is 2MP), probably lower RAM (mine is 256mb). This way I still don't know why (or how) it's considered T8585 - maybe because the form factor or mainboard? The basic question is... what makes a phone T8585 (as we can see, not the processor). I would go with the mainboard as an anwer.
- If I find a stock ROM for this phone, probably Maker and Model would have a valid info? I think it should have at least T8585 listed as Model!
Thanks...!

That is an HD2....KNOCKOFF. That is an HD2 clone obviously made in China. Do NOT try flashing an HD2 rom. Since the specs are so weak, your device may bootloop or even be bricked. It won't be able to handle actual HD2 roms because of the ram and processor (and key mapping may be inaccurate). It's considered as a T8585 cause that's what the makers named it. Just like if you went to China, you would see many Iphones which are not actually Iphones. Some of them even have an Apple logo (maybe slightly different but hard to tell without great examination). If you find a stock rom for it (highly unlikely) then yes, it should give you info. Now that's why the apps said they are incompatible. With such weak specs, (and I doubt that will have an armV7 processor) then they wouldn't work well. You could try this app to get more info on your device: https://market.android.com/details?id=com.bartat.android.elixir&feature=more_from_developer .

It seems to be armV5. MKT6516 processor.
I'll see what I find.
Thanks for all the help!
