NativeSD Rom Boot Script for HD2

http://xdaforums.com/showthread.php?t=1869673

many-many thanks to the devs & guys that gave us this!

But there are still a few out there that are new to this so here is what i did to make it simple to follow.

What's it about anyways, here one good answer from samsamuel

what you need:

- a good fast SD card, size depends on your needs (i tried a 4g Kingston that took forever to load, it could be fake/ damaged)

- MiniTool Partition Wizard Home Edition 7.6

- Download 4EXT Recovery from here. this is where the magic starts, thanks Xylograph/ securecrt

- for multi-ROM selection , thanks datagr

- for NativeSD Touch Recovery, backup & restore thanks tytung

- How not to Google Play when using diffrent roms so as not to always go to Google Play

I assume you already have Magldr/ CWM in your HD2 & know your way around the Magldr Menu.

First we need to format the SD card so that it will contain two partitions, ALL DATA WILL BE DELETED. so do a backup/ copy of your card.

- 1 FAT32 primary

- 1 EXT4 primary

Be very careful when using the minitool partition as you can accidentally format/ delete your Hard Disk Partition.

Insert you SD card to your PC & run minitool partition, something like below will show. Make sure you select the right drive.

Right click on the drive & choose "delete" then apply the changes, Again make sure it's the right drive! You now have an "unallocated" partition.

right click on the drive again & choose "Create New Partition" & change the dropdown boxes as the options below. Now move the mouse to the end of the "Size and Location" table. click & hold then move to the LEFT to leave a space for the EXT4 which will be done latter. Size will depend on how many Roms yo plan to use & how many apps you plan to install. Click OK.

right click on the drive again that has the "Unallocated" space & choose "Create New Partition" & change the dropdown boxes as the options below. Remember it should be Primary & EXT4. Click OK

Click Apply & when it's done you should have 1 FAT32 & 1 EXT4 Partition

Another method of creating an EXT4 partition

copy the "TOUCH" or "TWRP" or "RECOVERY" folder your SD Card (they all do the same thing)

no need to copy the others for now as it will be erased when you create/ format the EXT4 partition

Magldr > Service > Boot Setting > AD SD Dir > TOUCH

& this should run, Tap on Advance

Tap on Partition SD card

Ext size. = press the + sign to go up, swap size is 0 & make sure to select EXT4 then tap Partition

this is what info you can see using the "Recovery" Folder method

Magldr > Service > Boot Setting > AD SD Dear > Recovery (folder must be in SD root)

Time to Flash!

Magldr > Service > Boot Setting > AD SD Dir > TOUCH

Tap Install, notice that the compatible ROMS for this methoid have a div2 or NativeSD designation, tap on the ROM you want to flash.

Make SURE the ROM you Tap is the correct one

if you made a mistake tapping the incompatible ROM it will not go the Aroma installer but immediately will be flashed to NAND - erasing what ever you had there!

Install to SD-EXT

wait for it then your Done!

Magldr > Service > Boot Setting > AD SD Dir > NATIVESD

Run NativeSDBoot.apk, tap on whatever ROM you wan to BOOT to then re-start.

HTH :cowboy:

& BTW don't forget to hit the Thanks Button for the Dev's & Guys who made/ ported those ROM's to become NativeSD :highfive:
