[Guide] Android on your HD2 from start to finish

Hope this all makes sense, please ask questions here, not via PM.

Things you need to know about trying different OS's on your HD2.

I am putting this comprehensive guilde to help those that want to try other OS's and know they can go back to any OS without issue.

If there are any questions, please post them in this thread so others that might have a similar question/issue can benefit from the responses.

Sources: Various people from XDA and my own personal experiances.

Android:

First things first, what are the build types and what are the differences?

SD Builds: These were the first types of Android ROM's where the operating system is booted and loaded from the SD Card in to the devices RAM and run from there. This requires you to dual boot. You boot into Windows Mobile and then launch the Android boot from there. The data.img file determines now much "internal" storage you have for applications. This is updated on a regular interval so when you reboot your device, it is current.

NAND: The space where ROM's are flashed and loaded from is called the NAND space. Rather than having to boot into 2 operating systems as the SD version, you totally wipe Windows Mobile from your device and flash the ROM onto the device and boot straight into it. This makes your device more like a true Android device than other ways to boot.

Things you need to know/do.

1. Backup all your important data/settings
2. Decide if you want to run SD or NAND
-- Note: Many Dev's are not supporting SD anymore, but there are still some great Dev's working on SD builds for you to try
3. Read read read. Most importantly, READ THROUGH ANY IMSTALL INSTRUCTIONS BEFORE YOU FLASH/INSTALL ANYTHING!!!
4. If you are going to go NAND, decide if you want DAF or Clockwork.
-- DAF: This flashes the ROM directly from MAGLDR to NAND. Limited functionality on backups, upgrades (without wipes) and installing .zip mods
-- CWM (ClockworkMod): Becoming more of the standard as it gives you functionality from the Full Android Recoveries and other utilities.

THESE STEPS ARE NEEDED FOR ALL (SD OR NAND) ROM'S!!!!

First things first, you have to flash HSPL onto your device to unlock the bootloader for custom flashing.

REQUIREMENTS BEFORE STARTING!! IMPORTANT, PLEASE READ THIS!!

1. YOU NEED A RADIO WHICH SUPPORTS 576 RAM (2.08.50 or later should be fine but the Radio NEEDS to be 2.**.50.**). I recommed the 2.15.50.14 Radio: Multiupload.com - upload your files to multiple file hosting sites! I have had no issues with ANY ROM with this radio
2. YOU NEED HARDSPL 2.08 INSTALLED ON YOUR DEVICE TO FLASH MAGLDR (steps below)
3. Download MAGLDR 1.13 package and extract to an empty folder on your pc: xda-developers

FLASH HARDSPL (REQUIRED!! DO THIS BEFORE ANYTHING ELSE)

The Original HardSPL Thread: [HSPL/HSPL2] HowTo flash everything - xda-developers

NOTE: If you have Vista or Windows 7, update WMDC to v6.1 first: Download details: Microsoft Windows Mobile Device Center 6.1 for Windows Vista (32-bit)
NOTE: Turn OFF any AntiVirus Program first as it WILL interefere with the flash (there is NO harmful code in the program)

Note: HardSPL CANNOT be installed via microSD Card.

IMPORTANT: To install/uninstall this HSPL3 there must be any SPL version from this list on your device:
SPL 1.42.0000, SPL 1.62.0000, SPL 1.66.0000, SPL 2.07.0000, SPL 2.08.0000, SPL 2.10.000

To Uninstall you can flash a Stock ROM via SD card or use HSPL3 application (You need select 2.08.0000 in the choose screen)

1. Download HardSPL package and extract to an empty folder: xda-developers
2. Synch Phone with PC in Windows Mobile!!! It has to be connected to activesync or WMDC via USB cable
3. Run HSPL3_PKG.exe from your pc and read all the text carefully
4. When finished reading click next in the HardSPL program
5. The program will now check the usb connection and enter bootloader screen (tri colour)
*You can select between SPL2.08.0000 or 2.08.HSPL. This is to avoid people with 1024LEO's installing an incompatable version and bricking their device*
6. Select 2.08.HSPL for HardSPL and click NEXT.
7. Your choice will be flashed to your phone.
8. When its finished the HardSPL program will pop up a box saying "Successfully Done" and the phone will reboot.
9. Click ok to terminate program.
10. Congrats, you just flashed HardSPL.

*Go into BootLoader Mode (turn off phone, then press and hold the VOLUME DOWN then Press and hold the POWER button. After about 3 seconds the tri-coloured screen should appear). Verify the screen shows the SPL or HardSPL you installed*

--------------------------------------------------------------
--------------------------------------------------------------

To Remove HardSPL from your Device or Flash back a Stock Rom and Stock SPL for Warranty Purposes

You can remove the HSPL by flashing an original SPL from microSD card OR by running the HSPL3 application (You need select 2.08.0000 in the choose screen).
* You can also use the microSD Card method to flash back your Stock Rom and Stock SPL that you originally had on your phone*

- Download a shipped Rom: 4shared - Shipped Leo ROMs - shared folder - free file sharing and storage
- Rename the extension to .zip
- open it with winzip and extract the RUU_signed.nbh file to a folder
- Rename it to LEOIMG.nbh and copy it to the root of a microSD card thats been formatted to FAT32
- Insert your storage card into your phone
- Enter Bootloader and follow onscreen instructions to flash

--------------------------------------------------------------
--------------------------------------------------------------

FLASH RADIO

Flashing Via ActiveSync
1. Download your required Radio and rename the extracted file to RUU_Signed.nbh
2. Sync your phone with the PC
3. Run CustomRUU.exe from the Radio's Folder and follow the instructions (if one isnt included then download it from here: xda-developers)

Flashing via MicroSD Card
Use same method as Flashing a Rom via MicroSD Card

-------------------------------------------------------
NAND BUILDS ONLY!!!!

-------------------------------------------------------
SD CARD ROM'S
-------------------------------------------------------

(Installing Android)

Radio Version > Radio needs to be 2.08.50.xx or more (x.xx.51.xx are not compatible)

1) Micro SDHC card

Should be atleast 4 Gb, Class 2/4/6/8/10
Formatted clean with 32 or 64 Kb cluster size

2) Install automatic boot loader on WinMo :

This allows you to choose between booting into Windows or Android on start up. From 2nd Android bootup onwards these programs will make it easier to load Windows/Android at startup and you can even specify autoboot into Android if you wish.
Download this as a cab file and install in the phone memory (not in SD card)
Android Loader v6.0 Final for HD2: [APP] Android Loader v6.0 Final for HD2 - xda-developers
Exceller bootloader: [APP] Exceller Multiple Build Loader for Android/Ubuntu **Updated August 18** - xda-developers

You can of course manually always boot up Android anytime from Windows File Explorer by running CLRCAD and then HaRET files included in the Android build (see below).


3) Android Build :

Download your chosen Android build on your computer.
Extract / Unzip the folder on the computer
Now copy into the Root of your SD card.
Folder should be labelled "Android"
Once copied into SD card you will see 2 files: CLRCAD.exe and HaRET.exe which have to be run to boot into Android.
There will also be other folders / files (Android Apps, initrd.gz, system.ext2, rootfs.img, zimage, startup.txt, ts-calibration) please leave them as they are.

There are many choices in builds available, such as - MDJ, Darkstone, MIUI,. Please search the forum to look at the different features. I can't advise you on what clothes to buy. The same reasoning applies to advising on Android builds, you have to find out what is right for you...Try the build, if you dont like it, just go for another build..copy and paste your new android folder over the old one and its done.....

4) Data.img :

Your build may have a ready-made one included in the build folder or available to download separately. Size of data image is upto you, 256Mb/512Mb/1Gb (or more). This determines the Size of your Android operating system space for settings and downloaded apps etc. Bigger size allows you to keep more apps etc.

NOTE: I have found that any data.img file that is larger than 1GB can give you issues with downloading and installing apps from the market. You will mostly get errors about "not enough space". The only way to fix this is to wipe and use a smaller data.img or manually install the APK (this does not always work though).

>> At start up if you have a ready-made data.img file, booting up in Android is much faster (5-10 min). (You can choose the image size yourself with this option)
>> If you boot up without a ready-made data.img (Clean Install), then this is created by Android system at first bootup which takes longer (up to 30 min) Here the system will choose its own set default image size depending on startup commands in the build. Its not easy to change this size once its created (although it is possible)


5) First Android Boot

Once you have reached this step you are all set. It really is that simple!

These steps are performed with the phone booted in WinMo
Charge your phone to 100%. This ensures proper battery calibration.

In your File Explorer open the Android folder on the SD card
Run CLRCAD - Nothing seems to happens - This is normal. !!!
Run HARET - Small pop up window with grey progress bar appears with message HaRET LINUX BOOTING - You should then see some text lines in the top left corner of the screen and then a Splashscreen (blank screen with a HTC logo) Please be patient and allow time for the initial bootup.

If Android loads successfully, then (depending on your build )another Splashscreen will appear and then the Lockscreen for Android is launched.

Set up your phone for first use as per onscreen instructions and let all account finish syncing before doing anything else

Once you are up and running here are some of my own tips to maintain your system.

1) Always back up of your data.img file on to your pc/mac (weekly)

This is better done in WinMo. This will mean that you can always have a failsafe arrangement for troubleshooting.

2) Troubleshooting (If you start getting data corruption errors or force closes .

> Make another Clean Install of the build -Boot into Android- Reboot in WinMo - Connect to Computer - Copy backedup data.img file into the New (compatible) Android folder.
DONE! you are back where you started. All apps, settings, contacts,emails, messages are saved as they were at the time of backup.
You can also use a backup programme like Titanium Pro. This is useful when going over to a completely different chef build as you cannot (usually) take your old data.img file across.

3) Changing kernels

Follow instructions on the relevant thread.
For MDJ / Hastarin Kernels the following steps work
Boot up in windows - copy 'zimage' and 'Root' folder (which has modules) from the new kernel and paste into your /Android folder on SD card (i.e replace zimage of old kernel).-
Boot up android - check for successful upgrade under Settings>About phone>Software>Kernel ... the new kernel should be listed.
On boot up android will copy the contents of the /Android/Root folder to the relevant place.
If upgrade is successful then while in Android use a File explorer (with root permissions) to delete the 'Root' folder within Android folder, as this is no longer needed.
Note: Some kernels require the Modules (wifi,bt,lights etc) to be copied manually using Root File explorer while booted in Android. Please check the relevant posts for correct steps.

4) Upgrading Android Builds

I always do a clean install i.e let the Android build its own data.img with a clean formatted SD card.
Once this is done then copy your old backed up data.img and overwrite the newly created data.img to get all your info and settings as they were.
Caution: data.img is usually not compatible across different chef builds and its best to start a clean install if you are going to use a completely different build altogether. You can get you settings back by using a backup programme such as Titanium. Google sync will get your Contacts and Calendar back anyway if you have synced it previously to Gmail account.

5) Improving Battery Life

Having read through a lot of forums and trying out various techniques here are tips that have worked for me.
Charge your phone in WinMo to 100% (Green LED) While still connected to charger boot to Android and wait for the LED to go green. Then disconnect from charger.
Autoboot before launching into windows/sense fully, I use Exceller autoboot in 3 sec.
Rebooting Android 2-3 times after initial install and letting it 'settle' for a 1-2 days
Turn off any functions not required e.g BT, WiFi, GPS, Autosync
Turn down screen brightness to minimum
Use a battery current widget to monitor drain
Conditioning of battery: Boot into windows when battery is @ 5%, Discharge the battery fully and let the phone turn off> charge fully to green LED while phone off >> Boot up in Android and continue charging till LED green>> One cycle every 2 weeks
Recalibration: In Android with File explorer (e.g ES Explorer), Choose settings, enable root access and then in Root delete ... /data/system/batterystats.bin . This should be done when 100% charged, Now disable root access in file explorer and close, Run the battery down fully and follow the step above...
Fully conditioned battery should show about 4.2 - 4.3 V charge at 100% (Free app Battery Indicator)
Dataswitch (free app) allows switching mobile data when phone is not in use such as during night time etc
I keep Airplane mode in windows as default before first boot in Android (Not sure if this really helps)
For me greatest battery drain seems to be when i am in area of poor phone signal> switching to 2G helps using Dataswitch app

Things that don't work:
Task killers are not really very useful according to Hastarin

 

Welcome. I worked hard to get our own forum section here, now that they did it for us, I want to make sure it gets used and stays of value.

 

In all honesty, depends on the ROM. Most ROM's out there are very good performers. I would beware of the Gingerbread ROM's, for now, because they have some pretty big issues. The Desire or Sense ROM's seem to do MUCH better. I am running a MyTouch 4G ROM and it's fantastic.

[Feb 10][ZIP][Incremental updates][TMOUS] Moto-MyTouch4G V3.2 [Kernel tytung r2] - xda-developers

I would HIGHLY suggest going through with the ClockworkMod Recovery method as it allows for incremental updates and no-wipe flashing of ROM updates (even if it is a whole ROM flash).

 

Welcome to the forums.

Ok, through Clockwork Mod, if you are running CyanogenMod 7, and there is an update released, you can download the update, Flash (WITHOUT WIPE) and reboot and have the updates.

The main things that would require you to have to wipe is if you change to another ROM build (like going from CM7 to a Desidre ROM or even another CM7 Based ROM), or, when the ROM Dev tells you that you need to wipe for an update. These are not too common but they do happen.

As for updates, you have to wait for a ROM Dev to incorporate the updates into their builds. They are usually pretty fast about it (like same day to a couple days out if your ROM has active support).

Also, the above link (at the time the post was written) was not a 2.3 build.

 

Link to me the version of the ROM you are running and I will see if I can merge these changes for you and get you a new ZIP that you can use with this support.

The zip file update includes and updated Kernel and Module libraries so they will have to all be merged in correctly to work right.

Thanks!

 

No problem for the offer.

As for the Emulator, never really used them much, but I am sure there are some guides out there on how to get one up and running with the SDK. Just never did it myself.

I'll poke around though and see.
