This Guide is only for T-Mobile USA HD2 with 1024 Mbytes ROM (1024LEO)
The ModelID for this version of HD2 is PB811200


If you have a LEO with 512MB ROM then please use *THIS* guide.

IF YOU HAVE ANY QUESTIONS PLEASE READ THE FAQ BEFORE POSTING.

PLEASE READ ALL THE INFORMATION IN THIS GUIDE BEFORE INSTALLING HARDSPL OR FLASHING A ROM/RADIO. IF YOU FLASH AN INCOMPATABLE ROM OR RADIO ON THE 1024LEO THEN THERE IS A POSSIBILITY OF BRICKING YOUR DEVICE SO PLEASE BE VERY CAREFUL!!

Before starting, backup anything you might want to keep after the new Rom has been flashed as all contacts, emails, texts, notes, Internet BookMarks WILL be lost!!

PimBackup is good and free (copy any mms attachments to your storage card or computer seperately)

*ONCE YOU HAVE FLASHED A HARDSPL ITS PERMANENT. YOU DONT NEED TO DO IT AGAIN WHEN FLASHING NEW ROMS OR RADIOS*

*DO NOT start another process while the flashing process is taking place*
*DO NOT click off of the status bar… Let it stay in the foreground*
*DO NOT let the Screensaver activate*

Any of these can lead to a bad flash and possibly brick your phone

*FLASH HARDSPL BEFORE FLASHING ANY CUSTOM ROMS OR RADIOS*

1. YOUR DEVICE MUST HAVE AT LEAST 50% BATTERY POWER FIRST BEFORE ATTEMPTING EACH STAGE

————————————————————–
————————————————————–

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

The Original HardSPL Thread is *HERE*

NOTE: If you have Vista or Windows 7, update WMDC to v6.1 *HERE* first
NOTE:
Turn OFF any AntiVirus Program first as it WILL interefere with the flash (there is NO harmful code in the program)

Flashing HardSPL3 via ActiveSync with USB Lead (thanks to Cotulla)

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)

Not all ROMs are compatible with 1024LEO, including old official ROMS.
Official 1.42 and 1.66 WON’T WORK on LEO1024, because there is no 1024 NAND memory support.

All custom ROMs which ARE NOT BASED ON 2.08+ T-Mobile ROMs WON’T WORK ON 1024LEO.

1. Download HardSPL package from *HERE* and extract to an empty folder
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 the bootloader screen (tri colour)
*YOU CAN NOW CHOOSE WHICH VERSION OF SPL OR HARDSPL YOU WANT TO FLASH TO YOUR PHONE*
*You can only 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 your desired SPL or HardSPL and click NEXT.
7. You choice will now 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*

3. DOWNLOAD AND FLASH YOUR PREFERED ROM

IMPORTANT: DO NOT flash any Rom unless it states in the 1st post that its compatable with the 1024LEO or the chef confirms its safe to flash on a 1024LEO. If you flash a Rom with a Base version before 2.08 then you will most likely brick your phone. PLEASE BE CAREFUL!!

IF YOU ARENT ABSOLUTELY SURE THEN DONT FLASH IT!!

NOTE: Check the Roms Thread for any specific Flashing instructions. If there arent any then you can use the following guide.

Flashing Via ActiveSync
1. Download your prefered Rom from the LEO Rom Develpoment Page and unzip/unrar it to your computer
2. REMOVE SIM and microSD CARDS!! (this is a precautionary measure and is not compulsory)
3. Turn phone back on and wait until it syncs with your PC
4a. If your Rom is a .exe (customRUU.exe is already included in the Rom file) then run the file
4b. If your Rom is a .nbh file then run the CustomRUU.exe
from the Roms Folder (if one isnt included then download it *HERE*)
5
. Follow onscreen instructions to set up your New Rom
6. Once phone has gone through the customisation procedure then replace Sim and microSD Cards
7. Perform a Hard Reset to clear any leftover data from your previous Rom (see intructions at bottom).
8. Set up phone as required and job done.

Flashing Via MicroSD Card

NOTE (PLEASE READ): If you flash a Stock Rom via microSD Card then it will overwrite your HardSPL with a stock SPL included in the nbh file. If you flash a v2.01 or later Rom (with SPL2.*) you will NOT be able to reinstall HardSPL onto your device and could end up bricking it. This does not apply to custom roms as they do not include an SPL. BE CAREFUL!!

1. Make sure your microSD is Formatted to fat32 (you dont have to delete all files but it is safer if you do)
2. Download your prefered Rom from the LEO Rom Develpoment Page and unzip/unrar it to your PC
3. Goto the Roms Folder and rename the .nbh file to LEOIMG.nbh
4. Copy the LEOIMG.nbh file to the root of your MicroSD Card
5. Plug the MicroSD Card into the phone
6. Reset the device while pressing the volume down button to enter the BootLoader screen, you will first see a tri-color screen with the phone and SPL Information at the top
7. Follow the On Screen instructions to start the update
8. After flash has completed, press the reset button with the stylus to reset the device.
