[HD2 Android Q&A, Help & Troubleshooting and Genera] MrT69:
Let me give a overview how to get (almost) every Image running within cLK v1.3.3 or MagLDR 1.13.

I have had the problem that I need send my device for service and repair. When I get it back it was running on a 3.14 O2 Image with the boot loader 3.03.xx because the Service Team has done the update for me.

Great service – bad idea!!!!

I don’t know why but this causes 2 Weeks of troubles and not fully working Android Images. I was Android running before and I flashed the old O2 1.72 WinMo back to keep the warranty valid for this device.

What was the problem?

More or less small issues but from my point of view this was not acceptable. I spend more than 1 week to sort this out and I found finally the solution. I have tried to flash also back 1.72 and flashing HSPL3 from there and lot of things. Nothing was working. The listed procedure is the only solution which was working for me to get my device back to working with Android. If someone has a better solution pls. post this here.

Last night I found this way and I was only one step away to sell my device on eBay because 3G was working but no Internet access.

When I was using Windows Mobile everything was working without problems which were a confirmation that the Hardware is not broken. But on ANDROID – nothing was working. This was really incredible because I have flashed just nearly every Image beginning from January. With every Image the same result – NO INTERNET, NO UPDATE but 3G was enabled. So selling the device or modifying the device with a huge Hammer was my last option. But giving up is not my favorite option ;)

Ok, let’s assume you will have an HTC HD2 with the latest O2 Image (RUU_Leo_S_O2_DE_3.14.207.1_Radio_15.42.50.11U_2.15.50.14_LEO_S_Ship.exe) and the 3.03 boot loader. If you have this installed on your device you need to become a flash junkie to get ANDROID proper running on your device. I don’t know if other providers are causing the same problem but for O2 devices this will work.

If you have any troubles with ANDROID and HD2 just do it within this way and flash your device with this procedure EVEN if you have experience and if you know what CWR, cLK and MagLDR is.

All things you need are available within ONE PACKAGE at the end of this FAQ. Just download it and you have EVERYTHING you need. Read it, do it, enjoy it!

First at all:

O.k… now, let’s start:

1. Remove the 3.03 boot loader

REQUIREMENT: HSPL4.exe and HSPL3.exe

Your device is running on Windows Mobile 6.5 and when you check the boot loader you will see 3.03 within the display. BUT – how can you see this boot loader information? Damn easy…

For this you need to switch off your device. Keep the VOLUME-DOWN button pressed and switch on your device. When you see the RGB colored boot logo release the VOL DOWN button you will see now the famous boot loader of the HD2.

If you have the device connected to your PC you will see “USB” within the white area. If you see the “SERIAL” information just connect your USB cable to your device and PC and it will automatically switch to “USB”. If this is done, you are ready to go.

Now run HSPL4.exe and be patient. Do not run HSPL3.exe because this will not work with boot loader 3.x. After 10 or 15 seconds HSPL4 will give you an option that you are now able to flash the boot loader with 2.08 or HSPL 2.08.

Flash it and when it’s done the reboot will automatically after it’s done. Don’t panic, this will take round about 30 to 45 seconds.

Let the device boot into Windows and get ready to run HSPL3.exe. Reboot your device and press the VOLUME-DOWN Key again. Now go on with HSLPL3.exe and flash now the HSPL 2.08.000 to your device. This will take some seconds and you should see the “…hacked…” screen on your device.

IMPORTANT:

The “….we hacked it…” splash is the READY TO GO TO ANDROID for you.

2. DEVICE update

REQUIREMENT:

RUU_Leo_S_HTC_WWE_3.14.405.2….exe

Your Windows Mobile is still running because Windows is not claiming about changing the boot loader of your device. Start up your device boot into your windows mobile and run the RUU_Leo_S_HTC_WWE_3.14.405.2_Radio_15.42.50.11U_2.15.50.14_LEO_S_Ship.exe to update your device.

This will update your current Windows and also the Radio firmware on your device. Just run it and wait for round about 10 or 15 Minutes until everything is done. Now you have an English Windows OS on your HD2 and the RADIO firmware is also up to date. Don’t care about if you like or dislike English OS on your device. You need this only to …hmmm… let’s say “unlock” your device. I don’t know why or what this Image will do on this device but it’s important for ANDROID to flash it.

3. Run Task29.exe

REQUIREMENT: Task29.exe

Switch off your device again and keep the VOL-DOWN button pressed again. Now you will see a lot of Numbers and also HSPL 2.08. Yeah… this is what we want to see and what we need to run ANDROID on it.

Start the Task29.exe, make your confirmations and NEXT clicks and wait. When everything is done your device will reboot and you will see the whit HTC logo and nothing will happen anymore.

This nice tools will „format“ your device and everything within the ROM will be erased. If you see this logo you are ready to prepare your device for ANDROID.

4. SD-Card and LINUX partition

REQUIREMENT: SD-Formater and MagLDR 1.3

No worry, you don’t need to GOOGLE how to do this or note down the commands to do this. You just need to flash the MagLDR 1.3 and press some keys on your device.

I recommend a SD-CARD Class6 with 8GB. 4GB is also good but from my point of view it’s the minimum you should use.

Insert the SD-Card to your PC and start the PANASONIC SD-CARD FORMAT TOOL. It’s Chinese and English mixed but you only need to start it and click on “FORMAT”. You don’t need to copy some data on it for the Recovery also known as “CWR” because you will do it within the next step by flashing the device. Unplug the card and put it back into your HD2 device.

Now go to the folder “05 – MagLDR113” and run the MagLDR113.exe in it. Follow the screen on your PC and flash MagLDR on your device.

When this is done your device will boot into MagLDR screen and you see a lot of options. No worry, you only will need Option 8 and Option 5. All others are not important for the first flash.

With the VOL-DOWN and VOL-UP you can move within this menu. Select Option 5 – USB FLASHER and go ahead on your PC within the folder 07 – DAF-FLASH.

Select the DAF.exe and go on to flash your device. With this your device will be formatted with LINUX partitions which are required for ANDROID. With this step you will also flash the RECOVERY partition on your device which is required to flash almost all the Images. More and more the Cheefs will go away from DAF Images.

With this DAF.exe you will flash a 400MB system partition. But – why is this important? This information is important because some images requires space on the device and others not.

If you download an Image which you want to flash on your device always take a look at the point where the Cheef give some information’s about the flash procedure.

Let me give a short example.

Take a look within the 07 – DAF-FLASH Folder and open the flash.cfg with a text editor. DON’T USE NOTEPAD FOR THIS!!! USE NOTEPAD++ or WORDPAD from Windows, but NOT NOTEPAD!!!

With my package I have add an Image which requires a 400MB system partition. If you found an Image which requires a 150MB partition than you need just change the value 400M to 150M.

Reboot your HD2 phone, keep the POWER BUTTON pressed and you will enter the MAGLDR Menu. Choose Option 5 – USB FLASHER and run the DAF.exe with the modified flash.cfg.

Your device will be prepared with a 150MB system partition, recovery will also flashed on your device and you are now ready to flash your downloaded Image.

5. RECOVERY or CWR Mode​

Recovery sounds very dangerous but it’s not true or let me say the right word. This is only a Micro Linux for your HD2 which is required for doing some nice things with your device and flash ANDROID images to your device.

With my Image a SD-CARD with a second partition is required. And how to do this? You have 2 Options.

You can download GPART from the Internet which is a linux live CD and boot your PC with this disc. GPART is a nice GUI which can format your SD-CARD but if you select the wrong disc you need to reinstall your windows.

A better option for beginners is the device intern option which is provided by the RECOVERY option.

When your device is within the MAGLDR Menu select Option 8 – AD RECOVERY and enter the Recovery Menu. You will now see these options:

Now select “ADVANCED” and within the next Menu select “Partition SD Card”. Depends of the size of your SD-Card you can now select the “EXT SIZE”. On 8GB or 4GB Cards I recommend you select the “- 2048M” Option.

The next you can select the “Swap Size”. Please select “- 0M” because almost this is not required.

Now confirm and be patient. Depends of the speed of your card and also the size it will take up to 15 Minutes until your card is formatted. When everything is done you can now power off your device. Remove the SD-Card and plug it into your PC.

6. Flash your 1st Android

Now your SD-Card is plugged into your PC and you will see that the card is now 2GB smaller than before. This is O.K. because the second partition is now an ext3 LINUX partition which is not readable by windows. No worry, you don’t need to have access to the card.

Go to the downloaded package folder 08 – ANDROID and copy the file “efp_v2_hd2_deshd_stock.zip” on your SD-CARD. Very important!!!!

Just copy the ZIP file!! DO NOT EXTRACT THIS FILE!! Only ZIP Files are flash able Android Images.

When this is done unplug the SD-CARD from your PC and plug it back into your device. Power on your device and you will back again within the MAGLDR Menu. Choose again Option 8 – AD RECOVERY and now within the recovery menu select now:

Within the next menu select now:

If you have pressed the PHONE Key you will see your file:

Press again the PHONE Key and your Image will be flashed on your device. You will see some information’s about the Image and the text will scroll. It will take round about 5 to 10 Minutes until the Image is written to the device.

Power off, wait a view seconds and powers on again. The first boot of every installation will take some minutes. Please be patient again. I recommend waiting 20 minutes until you should use your device because even when you see the ANDROID login screens some additional installations and settings running within the background. When this is done, REBOOT your phone again and from now you can use your HD2 with a smooth running ANDROID on it.
