[Upgrading, Modifying and Unlocking] gunjahman:
Since the first guide was useful to some people, I'm posting another one: How to Install NAND Android on HTC HD2 without ClockWorkMod Recovery. The first three steps are the same. All this stuff is not mine. I've just gathered other peoples postings. So all thanks shloud go to them. I'm just a bug.

How to Install NAND Android on HTC HD2 WITHOUT ClockWorkMod Recovery​

(updated 12 March 2011)

Prerequisites

HSPL3 ~ SPL-2.08.HSPL or HSPL4

Radio that support 576 RAM (ex. radio ROM 2.15)

DFT MAGLDR Bootloader

Make sure that you have all the prerequisites installed.

STEPS:

A1: Install HSPL3

or

A2: Install HSPL4

B: Install radio ROM 2.15

C: Install MAGLDR on HTC HD2

D: Install NAND Android on HTC HD2

A1: Install HSPL3

Prerequisites

* Windows Mobile Device Center installed on Windows Vista / Windows 7 or

* ActiveSync installed on Windows XP

* You must have any SPL version from this list on your device:

o SPL 2.07.0000

o SPL 2.08.0000

o SPL 2.10.0000

(To check your SPL version, hold the Volume Down button and do a reset)

You should have this SPL version unless you are using the latest 3.14 ROM with SPL 3.03.0000. No worry, just downgrade your Windows Mobile ROM from v3.14 to v1.66 will do. Download HTC HD2 v1.66 ROM. Then downgrade your phone from SPL 3.03.0000 to SPL 1.42.000.

Step by Step Guide

1. Power off your phone.

2. Press volume down button (don’t let go) and power on your phone.

8. Select ‘ActiveSync’ and click ‘Done’.

9. Open HSPL3_PKG.zip with 7-Zip.

10. Copy HSPL3_PKG.exe to desktop.

11. Execute HSPL3_PKG.

12. Follow onscreen instructions to install.

16. After installation, you should see ‘We hacked it!’ on your phone.

17. Click on ‘Yes’ and your phone should be rebooted and load into Windows Mobile.

18. Disconnect USB cable from phone.

19. To verify, power off your phone.

20. Press volume down button (don’t let go) and power on your phone.

A2: Install HSPL4

Prerequisites

* Windows Mobile Device Center installed on Windows Vista / Windows 7 or

HSPL4 includes SPL-2.08.0000, SPL-2.08.HSPL, SPL-3.03.0000 and SPL-3.03.HSPL. The 3.03 SPL supports LEO1024.

You still need to use SPL-2.08.HSPL to use NAND Android and Windows Phone 7 and MAGLDR.

24. That’s all.

B: Install Custom Radio ROM

Prerequisites

* HSPL3 ~ SPL-2.08.HSPL

In order to flash custom radio ROM, you need to have HSPL3 installed on your HTC HD2. By the way, I used Radio Leo 2.15.50.14 on my guide. You can use it or any other HTC HD2 Radio ROM version.

HTC HD2 has 576 MB physical RAM but was reduced by software to 512 MB only. And custom Windows Mobile ROM + radio 2.07 or above can unlock it to be 576 MB again. Certain custom Windows Mobile ROM need higher radio version than your phone. And NAND Android requires it too. So you need to install custom radio ROM (if you don’t have the correct radio version).

Step by Step Guide

1. Power off your phone.

2. Press volume down button (don’t let go) and power on your phone.

3. It will load into bootloader.

4. You should get ‘Red, Green, Blue and White’ screen with SPL-2.08.HSPL.

5. Take off the battery.

6. Power on your phone.

7. I have R 2.06.51.07 at bottom of the screen with green HTC Logo.

8. Connect USB cable from PC to phone after Windows Mobile loaded.

9. Select ‘ActiveSync’ and click ‘Done’.

10. Open Radio Leo 2.15.50.14.rar with 7-Zip.

11. Copy CustomRUU.exe and RUU_signed.nbh to desktop.

12. Execute CustomRUU.

13. Click ‘Yes’ if User Access Control prompt up.

14. Follow onscreen instructions to install.

15. Bootloader will be loaded with USB status during starting of installation. (~10 minutes)

16. Phone will be rebooted after installation finished.

17. You should have R 2.15.50.14 at bottom of the screen with green HTC Logo.

18. Disconnect USB cable from phone.

19. That’s all.

C: Install MAGLDR

In order to install NAND Android on HTC HD2, you must install DFT MAGLDR Bootloader first. And the good news ~ both LEO512 and LEO1024 are supported. This means US T-Mobile HD2, Europe, Asia and the rest of the world’s HTC HD2 are supported.

Note – by installing MAGLDR, you cannot boot into Windows Mobile anymore. So everything on your phone is gone…

Prerequisites

* HSPL3 ~ SPL-2.08.HSPL

* Radio that support 576 RAM

No worry, Android on NAND is working. That’s the reason we install DFT MAGLDR Bootloader on our HTC HD2, right? And we will be able to load a Windows Phone version when a new ROM comes out. Okay, let’s get started. If you don’t have HSPL3, please install it and also install radio ROM 2.15.

Step by Step Guide

1. Power off your phone.

2. Press volume down button (don’t let go) and power on your phone.

3. It will load into bootloader.

4. You should get ‘Red, Green, Blue and White’ screen with SPL-2.08.HSPL.

5. Take off the battery.

6. Power on your phone.

7. You should have R 2.15.50.14 at bottom of the screen with green HTC Logo.

8. Connect USB cable from PC to phone after Windows Mobile loaded.

9. Select ‘ActiveSync’ and click ‘Done’.

10. Open DFT_LEO_MAGLDR113.rar with 7-Zip.

11. Copy MAGLDR113 folder to desktop.

12. Enter MAGLDR113 folder.

13. Execute ROMUpdateUtility.

14. Click ‘Yes’ if User Access Control prompt up.

15. Follow onscreen instructions to install.

16. Bootloader will be loaded with USB status during starting of installation.

17. Phone will be rebooted after installation finished.

18. DFT MAGLDR Bootloader will be loaded then.

19. Disconnect USB cable from phone.

20. That’s all.

D: Install NAND Android

Prerequisites

* HSPL3 ~ SPL-2.08.HSPL

* Radio that support 576 RAM

* DFT MAGLDR Bootloader

Make sure that you have all the prerequisites installed.

Step by Step Guide

1. Power on your phone.

2. DFT MAGLDR Bootloader will be loaded.

3. Use volume down button to go down to 5. USB Flasher.

4. Then press call button to load Android Flasher mode.

5. Connect USB cable from PC to phone.

6. Open your favorite ROM (ex. DFT_LEO_NAND_Android.rar) with 7-Zip.

7. Copy DFT_Android folder to desktop.

8. Enter DFT_Android folder.

10. Follow onscreen instructions to install.

11. Click ‘Yes’ if User Access Control prompt up.

12. Phone will be rebooted after installation finished.

Maybe the next steps are not obligatory, depending on the ROM you are going to install. In my case, I didn't have to follow the rest of the process, because the ROM I've used, has done the job itself and my phone was ready to work. (I've used CleanDroid and I had PERFCET results. Very light, clean and stable ROM. I've installed 30-40 apps and still is stable, alive and kicking.)

13. DFT MAGLDR Bootloader will be loaded then.

14. Use volume down button to go down to 3. Boot AD NAND.

15. Then press call button to load NAND Android.

16. Disconnect USB cable from phone.

17. Follow onscreen instructions to setup Android settings.

18. That’s all.

Alsomaybe the next steps are not obligatory.

To make auto boot to NAND Android.

1. Restart your phone.

2. Load to DFT MAGLDR Bootloader

3. Use volume up button to go up to 10. Services.

4. Then press call button to load Services Menu.

5. Then press call button again to enter AutoBoot settings.

6. Then press call button again to enter Boot source settings.

7. Select 3. Android from NAND with call button.

8. Use volume up button to go up to 10. Services again.

9. Then press call button to load Services Menu.

10. Then press call button again to enter AutoBoot settings.
