For those of you who had read my previous contribution of Steps to switch HTC HD2 WM to AndroPlus Android OS, in here I will shed some light on the MAGLDR options in more detail. MAGLDR is a custom boot loader for the HTC HD2, developed by Cotulla, who is XDA-Developers forum member.

As being indicate by its name, it loads the operating system, it does not replace your default bootloader already installed on your mobile, it simply executes after it. Giving you the possibility to maintain your original bootloader and if you wish to uninstall it later, you can still boot your mobile. As you must have seen in the previous article, MAGLDR enables you to install and boot the "ClockworkMod" (referred to as "Clockwork" or "CWM"). That option we used and described in previous article. Now, we will go through the other options of MAGLDR for you who need more details.

Partitioning Information

ClockWorkMod (CWM) is a custom Android recovery option. It is needed in order to replace the operating system that comes out of the box with the HTC HD2 device. In mobile computing lingo, the default OS is often referred to as "Stock ROM" and the act of bypassing a mobile device in order to replace the Stock ROM is called "Flashing."

Was this helpful? Yes | No | I need help

ClockWorkMod can only be installed on devices that natively supports Android operating system. The HTC HD2 does not natively support Android OS. So in order for ClockWorkMod to be installed, the MAGLDR bootloader must be installed first.

Was this helpful? Yes | No | I need help

When installing ClockWorkMod, the entire partitioning setup of your phone's internal memory is built on the fly. This process allocates fixed sizes to the phone's system and data partitions. The sizes of these partitions, especially the system partition, are critical to the installation of a new ROM to your device. So it is imperative that you determine the required system partition size of your custom ROM and choose the appropriate version of ClockWorkMod to install.

Was this helpful? Yes | No | I need help

  1. 1
    150 MB
    Was this step helpful? Yes | No | I need help

  2. 2
    250 MB
    Was this step helpful? Yes | No | I need help

  3. 3
    400 MB
    Was this step helpful? Yes | No | I need help

In the case of AndroPlus ROM, it requires a system partition of 135 MB, so the 150 MB version of ClockWorkMod should be installed.

Different modded ROMs could require different partition sizes so it is essential that you check on the custom ROM developer as to which of the above mentioned sizes works best for the ROM you are going to flash.

Was this helpful? Yes | No | I need help

Choosing a smaller partition size than what is required could leave your device to function improperly. While allocating a size bigger than needed could compromise the space intended for the data partition -- the part of your phone's internal memory that houses your user data (apps, contacts, messages, etc.)

Was this helpful? Yes | No | I need help

Check Current Partitions

ClockWorkMod also provides functionalities that allow you to check the current partitions of your HTC HD2 device and perform actions on them.

In the ClockWorkMod main menu, click on the Mounts and Storage option. You will be presented with options to mount, unmount, or format items preceded with a "/" symbol. These items are the current partitions present in your device.

Was this helpful? Yes | No | I need help

You need to be extremely careful when navigating through these options though. Be sure that you know what you are doing before selecting any of these options, as these could potentially lead you to lose your phone's data or worse, even leave your phone in an unusable state!

Connect card reader to HD2 HTC

description

With a connected card reader to your HD2 HTC, also called the HTC Leo 100, you have a way to not only read a memory card, but a way to transfer data and photos to your Laptop or PC. There are many other reasons to connect a card reader to your HD2 HTC.

Was this helpful? Yes | No | I need help

  1. 1
    Reasons to connect a card reader to an HD2 HTC:
     
    1. Card readers are dependable. If you should ever have a damaged memory card, a card reader can still read the card. However, if you rely on the memory card itself when it is damaged in any smart device, it will lock up, and stop you from further access to the data.
    2. Without a card reader a mobile device will deplete its battery more rapidly when data is transferred. Once your battery is dead, and you are sending data with only a memory card, your data is usually damaged.
    3. The processing speed of a memory card is much faster using a card reader than if you have only the memory card in your device.
    4. A memory card reader is universal with all memory cards. You can use it with other devices, too.
    5. The memory card connecting cable, connectors, and the card connector are all very durable. This is important if you are often exchanging information between your HD2 HTC and computer.
    6. A card reader can be read from your computer or HD2HTC without connecting directly to the device. Without the card reader, you must connect directly to your device via a Firewire cable or Universal Serial Bus (USB). If you use the card reader, all data is stored with ease. It not only saves your battery, but saves the wear on your HD2 HTC.
    Was this step helpful? Yes | No | I need help

  2. 2
    A card reader for your HD2 HTC can be versatile.
    If you have other "smart"devices, such as a digital camera, computer Tablet/notebook, Laptop, or other mobile device, each of these will use a different memory card. With what is called a "multiple memory card reader", you can use it for all of these devices. Such a reader possesses multiple card slots to accommodate the cards from all of your devices.
    Was this step helpful? Yes | No | I need help

  3. 3
    Memory card readers for the HD2 HTC - Each of these card readers is easy to connect to your HD2 HTC, and very reasonably priced.
    They are available online or at your local tech supply center.  
    1. The Cellet USB microSD/microSDHC Reader for the HTC HD2- It features a compact size for easy transporting. It is super easy to install and use. You can have it for about $10.00.
    2. SanDisk MobileMate Micro Reader for the HTC HD2- With this "gem of a card reader", you can transfer all of your videos, photos and tunes between your mobile device and computer with a simple plug-in to the USB port of both devices. It is yours for only $12.00.
    3. The SanDisk 16GB microSDHC Card - If you have lots of music, videos, and photo albums, this is just what you need. It is a worthwhile investment for sharing your media, and costs only $20.00.
    Was this step helpful? Yes | No | I need help

  4. 4
    If you are having a problem with your HD2HTC and the memory card reader:
     
    1. Try restarting the mobile device �" Press and hold the power button at the bottom of the HD2 HTC. Often this is a quick-fix, and all you need.
    2. A Hard Reset may be needed �" If restarting your mobile device fails, a Hard Reset may work for you. You may have a software issue. Once you have performed a Hard Reset, your mobile device will return to all default settings. To do a Hard Reset using the "Settings" menu:  
      1. Go to your Home screen, and tap the "Settings" tab.
      2. Tap "Menu > All Settings > System > Clear Storage".
      3. Enter 1234, and then confirm the Hard Reset by tapping "Yes".
    3. Using buttons for a Hard Reset:  
      1. If your HTC mobile device is totally dead, you must remove the battery. Remove the back cover to get to the battery. If your mobile device is not dead, turn it off by pressing the power button.
      2. While your mobile device is turned off, hold down the "Volume Up" and "Volume Down" buttons.
      3. As you are pressing the volume buttons, press the "Power" button and then immediately let go of it.
      4. Press the "Volume Up" button when prompted to complete the reset. You can cancel the reset at this point by pressing any button other than the "Volume Up".
    4. Your battery may not be installed securely. Turn off your mobile device. Then, take out the battery and check for any visible damage. Reinstall the battery.
    5. If your HTC mobile device is damp, it will affect performance. Place the memory card and all other parts on a dry surface. Dry them completely with a hair blow dryer on the cool setting.
    6. If the card reader suddenly fails to read your card properly:  
      1. Turn off your HD2 HTC.
      2. Remove the back cover, and then pull out the battery.
      3. Make sure that the copper strips are clean and dry.
      4. Ensure that the SIM card is put back properly in place.
    7. Try the memory card reader in another USB port.
    8. Make sure that your mobile device is charged. If a mobile device is low on power, operational problems may arise.

As mentioned, there are several solid reasons why you should use a memory card reader. Using a memory card reader is usually simple, and is typically very reliable. However, if you are having difficulties with it reading your memory card, try the above steps.

Hi Yassora, Thanks for helping?

After flashing with HD2 Toolkit or the DAF.exe I can not reboot. Only way to reboot is to take out the battery, but not by key.

Is there any some inconvenient keys that are not working properly in your device in which it dies not allow you to do a reboot using the key functions, if not so the problem would be is that you have either pressed the wrong key combinations. To do a reboot first thing to do is turning off your device and then while it is turned on simply press the volumes up & down button followed by the switch on, you must at least press and hold the on/off button for about 2 -4 seconds and release it while still pressing the volume up and down buttons.
