For the SDEXT version, you need a CWM layout of 5/200/5. If your phone doesn't boot, try a higher than 200 partition.
For the regular version, you need a system partition of 380 MBs.
Follow the instructions below to flash the ROM for the first time.. if you're coming from a Windows Mobile based HD2. It's recommend to have your SDCARD ready with my ROM loaded on it already.
1. Download and install MAGLOADER.
Download and unpack MAGLDR1.13 from
Once downloaded unpack the MAGLDR package with your favorite tool. WinRAR or 7zip recommended. Go to the folder where you unpacked the MAGLDR package and run ROMUpdateUtility.exe. Check the checkmarks and hit next to flash, just like you would flash a Windows Mobile ROM.
The phone will reboot and go to the multi colored bootloader screen. After the flash is complete it will reboot and go IN to the MAGLDR. You'll see a text menu with 12 options. Go to Option 5 (USB Flasher) and hit the Green Send key on your device. It will put MAGLDR in flasher mode and wait for a USB connection. Let it sit on this screen for now...
2. Setup system partition and install Clockworkmod recovery
Download the HD2Toolkit. You can click here to get it > http://nrgz28.sylvester20007.com/HD2...lkit_setup.exe
(original thread at http://forum.xda-developers.com/show....php?t=1090783
Run the installer and install it. Now, after you open the HD2 Android Nand Toolkit, it will look like the screenshot at the bottom of this post.
if you have TMobile USA phone (with green
buttons at the bottom) then choose a custom
partition size and just click Repartition in the bottom left corner. After that.. input 380
you have a device with all white buttons at the bottom (an european/asian model) then choose Custom
on the left hand side and input 200
in the box that pops up after you hit Partition.
Now you get a green "DFT" screen.
Hit Next until it asks you to put the phone in USB Flasher mode. The phone should already be in USB Flasher mode from step one. The progress bar will go back and forth while the phone is being setup. Hit Finish when it's done.
The phone will reboot on its own and go back to the main Magloader screen with all the options.
3. Flashing the Energy ROM
Now pick Option 8 and go to "AD Recovery". Magloader will load the ClockworkMod Recovery where you can flash your ROM. This is the place to go when flashing future ROM updates or "patches". To get to this screen after you load a ROM, you have to keep the Power key pressed down as you turn the phone on. You don't have to do that now, however.
Now I assume you have my ROM on the sdcard already. If not, take it out and transfer it through your computer or card reader.... and plug it back in to the phone.
If you have a TMobile USA phone, you can skip this section and go straight to installing the ROM below... If you have the euro/asian model continue to read.
Go to the Advanced menu and pick Partition SD Card. Pick a size of 1024M
and let it do its thing. Make sure it doesn't error out. If it didn't, continue to flash the ROM below... Make sure to copy the ROM zip back to the SD card by using the "mount USB storage" feature of the recovery.
"Install Zip from sdcard" in the menu options and hit the Send key. Then choose "choose zip from sdcard" using the volume keys on the side and hit the Send
key again. Pick my ROM from the list and hit the Send key again. Pick "No", hit Send. Now the ROM is flashing...
When it's done, hit the Back key. "Reboot system now" is selected. Just hit the Send key to reboot the phone and boot the ROM !
4. Booting up Android for the first time
The phone should now be rebooting and the Magloader screen will briefly show up....
Towards the bottom the words Go! GO! GO! will show and then you'll see the NRG logo which means the kernel is booting up. Wait a few minutes and the phone will
be ready to play with...
5. Enjoy your new operating system !
