I see in most of the guides I've read here on XDA that people mention that not all the ROMs are compatible with the devices and it depends in many factors, but most of the time, the information either it's not mentioned or it's confusing (for me at least)
Is there a guide of some type that I can read to learn about all this?
I want to be able to go and test as many of the ROMS around here and see wich one fits best for me, and I want to do it without bricking or semi-bricking my phone.
For example, this phone I have right now I bought it from another person and it was already been tempered with. How can I tell what has been done to the phone (without having to ask the last owner)?
Been going around all the forum but I only get more and more confused from all the comments I've read.
Thanks a lot for the pointers/help/tips or whatever you can help me with!
