I'm sure this question has been answered before but the terms are so vague its difficult to search for. So I'm gonna ask and hope I get an answer or maybe someone can point me in the right direction to research myself.
What is a JQ1 ROM vs JPA vs JQ3? Is this in reference to the modems, I notice they have similar names (though not always)? I'm hoping this is something simple I am missing but I am willing do do the leg work if someone knows of a place with definitions or something.
One more question can you install any modem with these different ROM's or does the name infer the modem type that must be used with it?

To have the latest and greatest, or one that fits your needs better then what your service provider thinks your needs are.

No worries man, welcome to the community Chances are however you may end up with a few 'Just search!!' answers but I understand there is almost too much info to understand out there but do check out the sticky threads at the top of the HD2 rom development forum as there is a wealth of detail there.
In answer to your question: 'why would anyone want to mod the rom or mess with it? please kindly answer it.'
There are many reasons for doing this, I assume that you come from the 'HTC probably know whats best for their phone as they made it' point of view, this is not always the case.
Let's take a real simple example: There is a limited ammount of space in internal memory and the more you can get the better and some of this space is taken up by pre-installed applications and images that you may never use and some of these can't be removed simply by deleting.
This is where 'cooking' roms comes in: In order to remove those apps you have to create a new OS image (rom) without them in (this is cooking, which is generally performed by experienced people who will publish their roms in the roms forum) and then to be able to get that on your device you need to 'flash' the cooked rom (OS image) onto your device (think of flashing as installing the OS like you would windows from CD on a PC) , and viola you have a new rom on your phone which leaves you more space in internal memory to use for yourself.
There are obviously far more complex reasons for cooking roms (speed improvements, fixes, mods and changes to the UI) but in order to keep this short and simple I've used the above example. If you want to know more check the noob tutorials in the rom forum.
Be careful however, and ensure you read all the information you can search for / find in there as there are some potential pitfalls if you don't do it properly.
Thanks prime! I got it now :]
Hello everyone,
I've been an Android user for nearly a week now. Most of what I've learned was here at XDA. I'm very grateful.
The purpose of this post is to make a constructive criticism and help those who are are seeking information about rooting/flashing.
I have found that information in this forum is quite disorganized. It is there, but it's hard to find it. And sometimes to understand. The home page of XDA does have a FAQ, but it's quite poor. Often there are many discussions inside the same thread and it's hard to follow and to find the relevant part for you.
Here are some topics that I haven't really understood, even though I have searched for them (and in some cases asked) and which I believe are utterly important:
What is the difference between JPA, JPB and others? What is it different from the default firmware? What the characteristics?
What are the custom ROMs available? What are they characteristics?
How do I backup my default firmware?
Can I flash an European firmware into an American phone? If no, why? If yes, then why does it matter (and means) saying it's European?
Is ODIN the only way to flash a firmware? Couldn't we use ROM Manager, from Market?
What is Hard Reset/Factory Reset? Are they the same thing? How do I do it? Why/When should I do it?
What is OPS?
What exactly is the Quadrant Score? I've understood it's some kind of measurement on the phone's speed, but not much more...
These are just some of the questions I remember right now. There are probably others and also those which I have already figured out through digging up.
I think it would be easier if there were sticked threads detailing the procedures for rooting and flashing. With a FAQ in the first post. Take for example the Samsung Galaxy 3 GT-i5800: root, gps fix, upgrading thread that has (at time of writing) 3114 posts. It's too much to read to solve common doubts.
Please don't take this as a "lazy" posture of me. I think it would benefit everyone, those seeking answers and those who are tired of always hearing the same questions.
What do you think of doing a complete guide? I could help with my (limited) knowledge.
Am I the only who has some difficulties in finding Android kernels for replacing the ones often present in ROMS ?
Shouldn't there be a kernel exclusive thread, much as like the Radio one present in the WinMo forum?
What are your thoughts about this? How do you usually search for those kernels?
Best Regards.
a) Click search
b) Type "kernel"
c) Change drop down menu choice to "titles only"
d) Run search
Whats so hard about that?
I suppose you ran that search. I am well aware of the search function. That query will also show up ROM thread tittles among any other title with the word kernel in it. As most Rom threads put their used kernel in the title, they show up in the results.
There is nothing difficult in accessing the search function. But then why would in WinMo forums be created a Radio thread? Afterall, couldn't you run a query with the term Radio? You could, and you would see a lot of rom threads as well.
So, that isn't that much of an answer. I never said i couldn't find kernels. I said that i found it to be more difficult as I had to run a search query and browse trough a lot of results.
Still, good to see that you also use the same mechanism as I do.
Cheers

Hi guys, I was just about to flash my tab to gain some features and updates and I was about to use RomManager but couldn't find my model of tab on it.
So I started my search and came cross a number of threads that talk about flashing different parts of the firmware.
e.g. making voice calls (I'd love this but i'm with optus australia and they block... )
A kernel flash ..... sounds nice
a filesystem change
all of these sound great and I have been searching but I really don't know what is for general useage in the roms or what is specific to australian roms...
I just don't want to brik my rom....
any help
cheers
Are you willing to flash Euro ROM? I thought JM6 (can't even remember if this was Euro ROM) was the greatest, then JME.
I'm using RichardTrip OC Kernel+ext4 on JMI now and few things are broken: call volume is very small when turning it up pass 75%. If you go back to 75% it's louder LoL. Others mention video laggy. Other also suggest to go all the way to Modaco ROM. Oh, bluetooth is broken as well (when I was running Modaco kernel+JME ROM but Paul mentioned something about because the old ROM so he suggested switch to newer ROM).
If you want to convert to ext4, use Modaco kernel Jan/2x date. It's very easy. Just READ the steps and have good Roto backup to your PC first.
So there you have it. YMMV

Interesting_ well it's at least a place to start got lot's of searching terms now
so are the roms realesed based on performance and features since this is Linux we're talking about, I imagine that a major part of the difference is back-end as opposed to my old HTC trinity which replaced functionality as opposed to doing too much back end enhancements - Is this right? is there a list of features each rom has ?
cheers
It's probably best you go check out the "Developers" section. When someone posts a new ROM they usually give you a list of features.
Try reading the entire thread so that you can see if others are happy with the ROM or what issues they're having. After this, you can make an informed decision on which ROM to flash.
which order do we flash in?

yes but what is the next step - what rom do i need? A system rom, A kernel a firmware fix - or rather, so I don't brick the phone what order should these be done in I think that is a better question
I have already rooted the phone , made some symlinks to add functionality so i'm kinda noobish to linux but I can catch on
cheers for any more help
I have also not yet flashed anything, because I don't have a need to as yet. But if I were to flash any ROM it would be the MoDaCo ROM with an OC'd kernel. That seems to be most peoples ROM of choice as it keeps the device looking as stock as possible with a good performance enhanced backend by changing the FS type to ext4 (which is faster than the current FS) and obviously a faster processor speed. CWM is also added for good measure. This allows you to flash certain zImages and have a more robust recovery menu.
Hope that helps.

i see we have a forum for each carrier's android dev. i thought they were essentially the same save perhaps the radio, maybe the kernel?
the question i have is this, does this mean that we won't be able to swap roms between the carriers? are they really that different? or would it be as simple as injecting an appropriate kernel/radio and then they would work?
