Dual Boot HERO

Will it be possible to dual boot hero? Maybe:
1. 1.5 and 2.x rom to choose
2. 1.5, 2.x and a windows mobile (just to try) to choose
Thanks

I have an idea regarding that:
You'll have to modify initrc:
the first thing it has to do is offer a menu (like in recovery), where you choose your ROM
While installing the ROM, all directories are suffixed, for example, system1, etc1
and symlinked at the end of the installation to /system etc...
Second, depending on the rom version, the corresponding directories (system1/system2, etc...) are symlinked to /system, /data, /etc...
THEN initrc proceeds
Which means that all the symlinking part will have to be at the TOP of initrc, just after the PATH declaration.
This is just a concept; I didn't try it.
If you have the time do do so, let us know of the results.

A good approach i suppose, but i'm not able to transform it into a real try... maybe someone can?

This is very interesting, i can try to do this but i have to know 2 things:
1. How to build a Boot Menu
2. How a recovery works when flashing recovery
Do you know where can i find these infos?

i was thining about this the other day, it would be awesome.
And another thing, android can run on windows mobile phones, it would be great to be able to run windows mobile on android

The "boot menu" would be a simple shell script nested at the beginning of the global initrc,
mainly taking care of the proper symlinking/mounting

Why? I owned WM devices before and I know that porting a ROM from one device to another is not a problem for cookers (example: port HTC Touch HD ROM to HTC Diamond2) ...
Maybe the kernel/bootloader is the problem... WM drivers are tones out there.

Kernel is the problem...
Android is open source, WM no...

Just a thought, but i doubt it is posible to do it in initrc becouse of kernel issues but shouldn't it be possible to have 2 kernels built and symlinked and just make a app that let you choose what system to load next boot and make the intirc and kernel symlinks before reboot? I have no experience with android cooking but some old linux knowledge is still in my head i think. Correct me if i'm totally wrong.

Whoa you're confusing me xD
HTC knows how hardware is built so they can write drivers without problems
Android porting on WM is easier because it's booted using haret
So i was wrong, drivers are the problem not the kernel

Hmm, ok.
There is a emulator called Bochs.. it can emulate WM. Maybe we could run it on Android?
I did a little search on google and found out that someone got Bochs working but it crashed when loading the bios..

How 'bout this....
Maybe instead of playing tricks with symlinks and init.rc and all that.......
Make a boot image that does nothing but ask you "Into which OS would you like to boot?" and that replaces the "boot.img" with the new one you want. Then on each of the boot images (for each OS version), you have one of the commands to flash_image back the "menu" boot image so that the next time the phone power cycles you get prompted. Also, you put a timer in it so that if your phone reboots without you present there's a default (and you don't miss your morning alarm clock or something).

How do you dive into Android development?

For example how do you make programs that do 1-click rooting, or modify the official ROM such that it does not update HBOOT, or make mods for it? What programming languages do you have to know? What system environment (Windows, Linux, etc.) do you have to be running?

Try extracting the .zip, adding and removing apps is not that difficult; most of the .apk's are located in /data/app.

data/app is where you can put user-removable and other apps you want seperate from the system/app in a custom rom - has to be added to the rom itself like A2SD does.

Oh okay. So before trying my hands at developing a ROM I should try writing some apps first?
Edit: But my ROM Manager has a "Move to SD Card" button, which means it should be in /data/app?

Bump. Then do I need to be on a Linux environment? Any gurus can give some pointers to a newbie to the Android scene?

being on linux would be easier - knowledge of the OS would be better.
If you use Linux you can use dsixda's kitchen to sign and build the rom after youve finished adding removing, editing etc. It's going to be a case of trial and error, but you cant break the phone as long as you're using a rooted/su rom, without the HBOOT or radio in it. You might get a bootloop/freeze, or 57 force closes but you can always re-flash.

Say i wanted to remove certain preinstalled apps from the official Froyo ROM, how would i know which files to delete from the zip?

You'll find a lot of info on the following thread. There you're linked to Android Developers pages where the structure of a ROM etc is described. All the info you need is there.

I think I'll try writing some apps on Ubuntu before even thinking of maintaining and developing my own ROM. This way I can get close and cozy with the Android system and learn Linux. One question though: Is the learning curve steep?

If you have never had ANY programming experience before I would reccomend learning another language first, before trying to learn Java. Try vb.net if you have Windows, learn that and you get the gist of how to programme, then install Linux Ubuntu or another distro, familiarize yourself with the Terminal command line, then go on to learn Java, then the Android SDK, then make some apps, then learn how to modify roms etc. The last thing you want is a bricked phone

It's not as painful as it looks.
It worked for me with XP Pro sp3 and some drag n drop to the cmd window.
The important part is to make sure that the files are on the root of C:\.
That's where the program looks for the files...
Good luck and happy flashing...

It's pretty simple. Just be sure to follow the instructions and don't miss any step.

Just to be sure, even though Im pretty sure I know the answer to this question, I need and thr android sdk right?

I'm not sure if SDK IS needed to downgrade and root I just followed that link that tylerlawhon posted and everything went so quick that I honestly remember.
If you search UTube, there is a couple of great vids regarding ALL you might want to know.
I remember back when I was preparing for the transition to Android, I downloaded the FULL SDK.
What a 10+ GB mistake that was.
I think the basic SDK (android-sdk_r10-windows.zip) weighs in at about 32 MBs.
I can't remember exactly what I needed it for tho.
Here is the ReadMe from that file:
-----------------------------------------------------------------------
Welcome to the Android SDK!
The Android SDK archive initially contains only the basic SDK tools. It does
not contain an Android platform or any third-party libraries. In fact, it
doesn't even have all the tools you need to develop an application.
In order to start developing applications, you must install the Platform-tools
and at least one version of the Android platform, using the SDK Manager.
Platform-tools contains build tools that are periodically updated to support new
features in the Android platform (which is why they are separate from basic
SDK tools), including adb, dexdump, and others.
To install Platform-tools, Android platforms and other add-ons, you must
have an Internet connection, so if you plan to use the SDK while
offline, please make sure to download the necessary components while online.
To start the SDK Manager, please execute the program "SDK Manager.exe".
From the command-line you can also directly trigger an update by
executing:
tools\android.bat update sdk
For more information, please consult the Android web site at
http://developer.android.com/sdk/
Hope that helps.

Wow dude you saved my life. I checked YouTube and realized I didn't need anything I downloaded -___-

[Q] chroot Ubuntu on Nexus 7 (2013)

Not sure if anyone is interested or not but I have a chrooted Ubuntu 12.04 and Ubuntu 13.10 on my N7 running.
If anyone is interested I can post the steps and scripts I used, so you can do it yourself, and learn as you do it which is fun lol.
Most of the information is available via google searches however some things are not mentioned.
I have almost got LXDE running in the chroot without vnc, however not fully.
The problem I am having is when I startx or xinit /usr/bin/lxsession it displays a blank screen. When I kill the process, the LXDE background displays with a cursor. Not sure why it waits to display when I kill the process kind of weird.
Anyways thoughts, comments, constructive criticism.

photo of the adb screen launching startx img1.jpg
photo of the actual N7 screen img2.jpg

I guess there is a guide already from what I read.
No need for a guide unless someone wants to try making their own Ubuntu chroot. Then you will have the ability to make you own image size etc.
If anyone is interested or wants to do this post here and I will provide the steps.
And assist with scripts and what not.
By no means did I come up with this on my own, however many guides have scripts that don't work etc due to your version on android or device etc.

I'm using the guide in the General Section to use Kali PwnPad with my N7. I was using Backtrack with my 2012 and just bought a 2013 and very happy so far that everything works with Kali but with a better performance!
Wifi USB host was the main concern and it works great.
Nice job you have done too can you send me or share your chroot script please?

yes, do you need startup scripts or launch scripts for vnc and x
or just the chroot script to get into linux?

UPDATE
I made scripts which will allow the creation of the linux image right on the device itself.
It downloads approximately 200 megs for the packages, no more need to download huge image files...
Right now ubuntu works for sure testing others...

How To Get iOS 11 Open / Close App Animation On Android

Here’s how you can get iOS 11 new open and close app animation on an Android device running version 5.0 and up.
If you are an Android device owner who simply cannot find it within you to move away from the world’s most popular mobile operating system across to iOS, but you happen to admire certain facets of iOS, and in particular iOS 11, then you really need to be reading this. Thanks to the hard work of a single XDA Developers forum member,mizdrake7, it is now possible to get the iOS 11 open/close app animations on any Android 5.0+ device.
Companies like Apple and Google are continuously using new versions of their platforms to tweak certain experiences. We all pay attention to the large wholesale changes which ship with new major versions of iOS and Android, but very few people, aside from the purists, pay attention to the relatively minor refinements, such as the new opening and closing animations of apps that form part of the iOS 11 experience.
For those Android fans out there who appreciate a relatively minor but overly positive improvement, it’s now possible to get them on the Android platform. Unfortunately, this isn’t just a simple case of heading to the Play Store and downloading an app that brings this new experience. Because it is essentially modifying the default behaviors of the Android platform, it requires a device running Android 5.0+ with a custom recovery installed, which simply put, means you need root access.
If you have that covered, simply download the necessary ZIP file from here link:- https://drive.google.com/file/d/0B7fIOZZgI8cVUzJyZVhoalBsaFk/view?usp=drivesdk
, and then flash it through a custom recovery onto the device itself, as long as that device is running Android 5.0 or above.
The provided installer also creates an internal backup of the stock Android open and close animation, meaning that if you don’t actually like the new iOS 11 default, or simply tired of having an Apple-behavior on an Android device, then it’s possible to roll back to stock quite easily. Of course, this type of installation and project does come with the usual warnings that device owners should actually have some knowledge of modifying an Android device, and in particular, knowledge of flashing packages and custom recoveries.
This isn’t exactly the most inspiring change, or the biggest project ever to come to Android, but it’s definitely one that will have some lasting appeal to those who like finer, subtler, modifications that make all of the difference when using a device.
