I know the SDK has AVD, but it's outdated and extremely slow. You can install custom roms on it but only older ones because its based on the yaffs2 filesystem and most current roms use EXT4. I had high hopes for bluestacks too but its locked down pretty tight and I don't see us being able to flash roms to it anytime soon. We have emulators for pretty much everything else, something like this shouldn't be too hard if we work at it. Dynamic recompilation seems to be the best way to go, but feel free to give input if you feel otherwise.
I guess our starting point should be here: http://fms.komkon.org/EMUL8/HOWTO.html
The man who wrote the guide above is some high-end developer that builds emulators for Android, but he seems to be pretty knowledgeable. He has an email you can contact him if you need help with a specific thing: [email protected].
As they come in, I'll list all the information regarding developments in this project in the post below.

Wow! Looks an excellent project for Devs
I have few questions
1. Will be there a possibility to define and emulate specific devices?
2. How ROMs are flashed, the emulator will have a recovery too?
3. How many of you are working on it?

1.) One of the goals would be hardware and kernel emulation, I would imagine they could be set as variables where you could input your own kernel and we could make some predefined hardware options for you to choose from. It would be hard but I think it could be done.
2.) I don't exactly know, but seeing as that's how we already do it we could try. Early alphas would probably be more of a "kitchen" where your menu is in the terminal and you manually put your files in the respective folders.
3.) Just me at the moment, I haven't found anyone to help. I haven't really made too much progress either, right now I'm decompiling AVD to figure out how it runs.
If this works, it would be a lifesaver. I say we should PM you any predefined device settings we want, and have a drop down list that automatically sets it. And to emulate recovery I don't see happening like on our devices, but maybe some of the wipe features, and flashing over a current rom? Also anything you need for help I can do, just ask. I'm good at design, and UI, just can't create it myself. And can you possible make it cross platform? Because I switch between windows and Linux.

I'm using Ubuntu 12.04 right now, so it's going to be Linux at first but once its stable enough the plan is to make it cross-platform. And I do need help, I need all the help I can get! Hence community project haha.

I can live with Linux at first. And I know, but I mean any help a non-coder can give. I will at least test it, and give some device specifics, but anything else that I can really do?

Either way, I appreciate the help! Ill PM you if I need a tester and you should pop in every once in awhile to see how things are coming along. I'm not going to lie, this is harder than I thought it was but it seems do-able the more I study AVD.
I'm thinking we might be able to change the filesystem on AVD to run EXT3/EXT4 and get it to run a little smoother and build it to run without eclipse, then modify it to fit our needs.
That's sound good. And anyone who would get the most use of it would be fine with a terminal based one right now, and you can work on a GUI later unless someone else helps you soon. I'll keep checking as this comes along, hopefully it won't take too long to get a preview working.

You can use Qt for GUI, its easy.
Its based on C++ and hence is very fast than other GUI libraries.

I feel pretty confident in this project, I'm going through Androids source code starting with 1.5
I've been thinking this over, it would be much easier to add EXT3 and EXT4 support to AVD and tweak it for speed. Im working on it now, ill try to get an early alpha out as soon as I can put it together.

You'll wanna learn Java, specifically, Object Oriented Programming. Stick to one of the more popular Linux distributions since it'll be easier to get your computer set up and deal with driver problems and the like. For now, maybe Ubuntu would be your best choice.
Come on, don't blame on me,but do you have any ideas of Linux otherwise this will be a thread with only HOW-TO install Linux and how to fetch repo and mod them to destroy the main reason they were build. TO WORK ON YOUR PHONE !

Hi, I am interested in starting some custom ROM work for our device. I am just looking for a little bit of direction on where to start. I understand things are a bit more complicated with our locked bootloader, but I know there is still a lot to be done. What are some good places to start tweaking performance? How about graphics and theming? if there is anything else I should know that would be great. I am not an extremely experienced programmer, but I have some experience and I am fairly comfortable tweaking system stuff. Lastly, Is there any way to get an emulater going for the A2? this would be very helpful for development to save the pain of boot loops and errors on our real device. thanks for everyone's help! Hopefully our development will take off for this phone once we get the bootloader bypass working or get it fully unlocked.

I just wanna know because i own a non famous android phone which has very less roms and mods so i just wanna use this method to compile
ROMs for my phone from sources like cm repos.
i used to make pots roms for the lg p500, i tried to make one for my atrix 2 and nothing, i asked to some developers of atrix 2 (very famous by the way) and i tell them how i make those ports and they tell me that it was other metod for our atrix 2, and NEVER TELL ME WHAT WAS THAT METOD, I ASK LIKE 3 MORE TIMES AND NEVER GET AN ANSWER. It was depressing :crying::crying::crying:
Hi thanks for posting this tutorial and for your work. One thing would like to ask is if anyone no's of some more links or books as I would like to learn how to code and correct bugs and add features to ROMs or build my own. I would greatly appreciate any help thanks in advance.

From my understanding, you have to swap out the patches and it's specific to your device and ROM. I took a look at one of the patcher tools, but it was just a bunch of confusion to me until I can actually sit down and take a look without having to rush. Think you could take a look as well? Greatly appreciated :victory:

To use the patch you need your rom's source code then run the patch command on linux and patch your source add the resources and compile. There is no flash zip morphs or anything flash able because AOSP roms are not the same it will be hard to make a flash able zip for all and this is the development section if you don't know what to do then search, read and read some more instead of these consider requests that wouldn't happen.

Hey guys,
After having nearly lost all my data because android would not recognize my Decryption password I would like to try to compile frost.
I don't know if it will work for the HTC one but I really want to give it a try to help out other people who might have to factory reset due to encrytion problems.
It looks fairly simple to compile it, only I have never compiled any kernel .img before.
Before I actually try to compile it I would like to get advice on how best to do it and what to avoid while compilling.
Again I really want to get this compiled for the HTC one as this had me in a really bad spot.

lol, just have seen this.
The link to the University of Erlangen has some pretty neat resources, but I currently have no android phone to try making such a recovery image for.
For the case of (hopefully) your own phone you are trying to get the /data back: This software relies on the device having been unlocked not long ago. If the device was not unlocked for a week or so, you have no real chance of the keys being still in ram.
If you have a weak PIN, its bruteforce feature might work, if you have a strong one it may take very long. I'd recommend you to make a bit level image of the /data partition just in case (type man dd in your commandline in linux, the dd tool should also be in phone recoveries). And possibly try to encrypt it on your desktop that propably gets it done faster. Also you do not need to make a device specific recovery and you dont need to cross compile.
Also this: http://www1.cs.fau.de/filepool/projects/frost/frost.crackpin.tgz
might just work. Read through the README file in the archive, its straightforward.
thx good thing to konw
There's a reason they freeze the phone. If you hope to recover the keys from a phone that is powered off for anything like 5 mins or more forget it :/ . (The time really depends on the memory chips)

Will FROST be able to recover deleted files from the phones internal storage? I'll send strength your way so that you'll get your life to awesomeness again.
FROST only works if your bootloader is unlocked. Since unlocking your bootloader wipes data you're screwed (unless there's some hack to prevent this for your device bootloader). Image the phone or copy the encryption header and try to brute force/dictionary attack your own password key as much as you want without worrying about data being wiped. Download Kali Linux live CD maybe it has some Android forensics tools I think it does. If not google around for 'android brute force encryption' somebody will have tools to do this.
