ok thank you.
I asked also to attach the zImage that you have for the ROM
(plase alway answer to all questions/requsts I made in order to speed up)
the attached initrd.gz is working for me using MAGLDR
it boots and mounts:
/dev/block/mmcblk0p2 on /NativeSD
/NativeSD/Sense3.5/system bind on /system
/NativeSD/Sense3.5/data bind on /data
I used "Sense3.5" for the ROM NativeSD directory.
one question: which loader are you using? MAGLDR CLK or HaRET?
this is 2.6.35.14-marc1706s_desire_0.1.5+ kernel.
I think that it can't be booted from WM/HaRET......

Resize EXT4 Partition
Tytung's post immediately below yours gives a solution for us mere mortals who cannot get Gparted to work:
1) Backup all of your NativeSD ROMS to FAT32 using Tytung's NativeSD Touch Recovery
2) Use MiniTool Partition Wizard Home Edition 7.6 to
Let us know how this works as I will be adding it to my Wiki:

The answer to your question "What can resize the Ext4" can be found by searching this thread for the word "resize" as I think you discovered.However Xylograph's solution uses Linux.
Tytung's post immediately below yours gives a solution for us mere mortals who cannot get Gparted to work:
1) Backup all of your NativeSD ROMS to FAT32 using Tytung's NativeSD Touch Recovery
2) Use MiniTool Partition Wizard Home Edition 7.6 to
a) Delete 4EXT Partition
b) Extend FAT32 to take up the "free" space
c) Create a new 4EXT partiton with the size you want
3) Restore your NativeSD ROMS to EXT4 using Tytung's NativeSD Touch Recoveryb) Extend FAT32 to take up the "free" space

Code:
I use MAGLDR.My original method is the same with yours but woithout system/bin/sh.
But it(yours&mine) has a serious problem is that phone will reboot when you are installing apps.
In addition,can you attach MIUI(or other GB roms)'s NSD initrd.gz with your method?
I used your method to make it but cannot boot.

Hi, Xylograph
I would like to flash clk with your 4ext recovery. Would you recommend the most suitable clk version which could work best with your recovery? How about the flash method? Flash clk first and then flash 4ext within the touch cwm bundled with clk? Thanks a lot.

nativeSDMultiBoot Version 10
Hello all,
Here is the latest version 10 of the app.
Change log :
----------------------------------------------------------------------------------------------------------------------------------------
Version 10 :
Fixed : Small aesthetic changes
Added : Website button
Added : Backup nativeSD rom
Added : Restore nativeSD rom
To backup a rom, click [Backup rom] then click a rom that you wish to backup.
The app will create sdcard/RomBackups/toEXT4/rom_name/rom_name.ext4.tar
and sdcard/romBackups/toSD/rom_name.ext4.tar files.
These are your backup that you can save them anywhere before you do any tests.
To restore a backed up rom, click [Backup rom] then click [Restore].
You will see that the app is switched in [RESTORE MODE].
In [RESTORE MODE] click a rom that you see in the list.
(Note that you must NOT change anything in sdcard/RomBackups folder.
If you changed anything from there then you must put the files and folders as they were,
before you enter again in the app and restore or backup any rom.)
PLEASE READ THIS :
You must NOT touch the app while backup or restore operations.
It will be unresponsive during the operations
(You can use a debugger to see what is the app compressing or decompressing).
Enjoy the app and please hit the thanks button (yes, it's still free!)
----------------------------------------------------------------------------------------------------------------------------------------
Version 9 :
Changed : no need the rom_name.txt method anymore. (requested by Tytung)
Added : Thanks to the guidance from securecrt now the app is getting the name through linux shell command.
Changed : colored text to [Switch rom] section. Blue color means the current running rom.
Added: Tabs in switch and delete sections for bigger buttons and more beautiful interface.
Changed : improved performance of the app (I hope it's ok now Szczepanik )
----------------------------------------------------------------------------------------------------------------------------------------
Version 8 :
Fixed : [Delete rom] section that was messed up from a bug that I found and now it is ok.
Added : colored text to [Switch rom] section. Cyan color means the current running rom(or the latest clicked rom).
Added : rom name in the [Tools] section so you will know in which rom the changes will be applied.
----------------------------------------------------------------------------------------------------------------------------------------
Version 7 :
App supports switching and deleting up to 18 nativeSD roms.
App will read from /proc/self/mountinfo the rom name and compare it with the rom_name.txt
that is automatically created in sdcard/nativeSD folder.
If the name matches, then it will enable the [Delete] and [Tools] buttons.
If not it will hide those 2 buttons to avoid any mistakes.
Also some small bugs have been fixed from previous versions.
----------------------------------------------------------------------------------------------------------------------------------------
Version 6 :
Added : fix permissions in nativeSD roms
Added : clear Dalvik cache in nativeSD roms
Added : kernel update(*) for nativeSD ONLY roms (thank you master Tytung for the guidance)
(*) How to update kernel :
1) Download the zip file of the kernel (tytung 3.5 and securecrt 24Sep2012 kernels work perfect)
2) Rename it to [update.zip] and put it in the sdcard/nativeSD folder
3) Run the nativeSDmultiboot app and click [Switch] -> click your current running rom -> [Back] -> [Tools] -> [Update kernel]
4) Reboot IMMEDIATELY! (this is really important to avoid any force closes...)
----------------------------------------------------------------------------------------------------------------------------------------
Version 5 :
Now CLK users can use this app to switch roms! (You must put [mkbootimg.sh] and [mkbootimg]
from [flash_sboot_v2.zip] inside the folder sdcard/nativeSD/)
The interface has been changed also.
----------------------------------------------------------------------------------------------------------------------------------------
Version 4 :
On first enter please click on the rom that you are running now! THIS IS VERY IMPORTANT!
It will create a rom_name.txt inside the nativeSD folder with the name that you are running (thanks for idea securecrt).
I have also added the delete function with confirmation message (requested by Xylograph).
It will hide the rom that you are currently running to avoid any mistakes (requested by securecrt).
P.S. All fellows developers are free to include it in your nativeSD roms.

I dont know if this help or need somebody or even if somebody got it before but i go...
i have got to share user app between diferents NativeSD roms.
This can work with update-script at installation, with terminal...but i will explain with Root Explorer and 2 NativeSD installed
Be sure you can install apps, install one app and unistall it.
1. Go first rom without apps installed (to get this put file explorer with root access on system app)
2. Go /NativeSD/
3. Create folder name "app". It must look like: /NativeSD/app
4. Give permissions rwxrwxrwx to this folder.
5. Long click in "app" folder and select: "Link to this folder"
6. Go to /data/
7. Click in "Create link". It will ask if you want to merge bla bla...Yes
8. If you are using Root Explorer you will see rwxrwxrwx -> app in /data/app folder
9. Now you can test if applications can be installed...
Go second rom, test if you can install apps, unistall all user apps, file explorer with root access in system...
1. Go /NativeSD/
2. Long click in "app" folder and select: "Link to this folder"
3. Go to /data/
4. Click in "Create link". It will ask if you want to merge bla bla...Yes
5. Reboot
And you are done. Now you can go first rom, install app, go second rom and you will have it there.
But only app...data, settings...not shared with this method. To share data you will have to do this process with /data/data but this can be dangerous due to diferent roms, android versions, system data apps....
Can I share app and data between JB & JB , ICS & ICS and JB ( NexusHD2-JellyBean-4.1.2-CM10 V1.2) & ICS ( NexusHD2-ICS-4.0.4-CM9-HWA V2.7 )
Datagr thanks v10 looking good except first time I select Switch / Delete / Backup the first screen shows all the ROM names on top of one another - see screen shot.Hello all,
Here is the latest version 10 of the app.

NativeSD system file installer
This uses aroma to install system files to rom
1. Extract the folder
2. (Optional for other NativeSD ROMs) Edit install.sh using notepad++ by changing
to
3. Put your system files into the system folder, remembering to put them into correct folders first (eg .apks go into app folder in system folder, so you need to create that)
4. Re-zip the contents of the installer.zip (Don't zip the folder else you may create a folder within a folder and it won't work)
5. Flash via 4ext recovery.
Should work
If you aren't sure of what you are doing, don't try it. But if you do come unstuck, you can re-flash the original rom .zip.
Edit; You may need to fix permissions after installing, or use a root browser to set the correct permissions for the files you install.
Edit2; Thanks to aroma people, Xylograph, securecrt, tytung etc. I only fiddled around with it a tiny bit.

- Post 1 Introduction
- Post 2 ROMs, Scripts, Installer template for Devs by Xylograph
- Post 3 Q&A
Introduction
We have SD ROMs for very long time, but I think most of the people should agree with me that the SD ROMs are slower than NAND ROMs. because the SD ROMs use system.ext4 and data.ext4 files to store all the ROM contant on the FAT partition, the IO access is the bottleneck.
My Class10 SD card has 10MB/s R/W speed, but the NAND flash R/W speed is only about 4MB/s. so if we can directly install the ROMs to SDCARD and boot from SDCARD we will get lots of benifits:
- Faster Read/Write speed than NAND ROMs
- Bigger data partition for user space (depends on how big the ext4 partition on SDCARD)
- Install servel ROMs at the same time. and each ROM share the same space
- Muilt-boot support, easy to switch between the ROMs been installed.
The NativeSD Rom is a new kind of ROM it needs an ext4 partition on your SDCARD.
This thread will tell you how to install a ROM to SDCARD and give some script templates for ROM Devs to make the ROM installer which can support install the ROM to NAND flash or SD/EXT4.
Install the ROM to SD/EXT4 will not effact the ROM(WM or Android) on NAND flash, NativeSD should support run from MAGLDR CLK or WM6.5(need test).
Important Notes:
Backup all the SDCARD content to PC before you create the ext4 partition on SDCARD.

NativeSD Dual Installer v2
Keep in mind that this is a work in progress featuring a possibility to run a full nand rom on a SD-EXT partition..
Please check my current AOKP & PA jellybean ROMS or CM9ight ICS ROM for some 'NativeSD functionality' in action
Features:
- Compatible with every bootloader and stock OS
- Recovery package for users without Android on nand
Pre-Installation Requirements and recommendations:
- HTC HD2 Phone
- Sdcard with enough free space (performance may differ based on the quality of your card)
- 4EXT Recovery (Highly recommended)
- Primary Fat32 partition and Primary EXT4 partition
Downloads : (Please do not mirror stuff)
- Download 4EXT Recovery from here.
Pick the SD version if you would like to boot 4EXT Recovery from SD (unpack to your sdcard)
Pick the NAND version if you would like to flash the 4EXT Recovery on your NAND (flashable via recovery)
Users with non-working hardware keys can try the various touch recoveries I've ported , though I highly recommend 4EXT recovery.. - Dual_Installer_v2_example.zip (only for advanced users, unpack the contents to your computer)
Contents :
4EXTRecoverySD for users with no or a different recovery on nand:
Code:- Contains 4EXT Recovery ported for SD users. - Unpack to the root of your sdcard - Set your SD Boot to the Recovery folder or use clcad/haret to boot
4EXTRecoveryNAND for users who would like this recovery on nand:
Code:- Contains 4EXT Recovery for android NAND users - Flash it using DAF.exe (Magldr) cLK users can flash it using the HD2 toolkit
Dual Installer example Package (advanced users) :
Code:- Contains an example (not flashable!) of how I use this for my roms. - You can check all the stuff, folder structure and scripts. - I've tried to make the updater-script and aroma-config 'easy to read' - Placeholders with text on what to put where when porting stuff to NativeSD.
Installation Steps & Instructions:
Sdcard for NativeSD:
Code:1. First make sure you have at least 1 Fat32 partition and 1 EXT4 partition on your sdcard 2. If you don't have these partitions ?? [B]backup your sdcard[/B][COLOR="Red"][B] , because everything will be wiped from your sdcard when you create partitions and format them ![/B][/COLOR] 3a Use the [URL="http://goo.im/devs/Xylograph/Various/Recoveries"]provided 4EXT recovery (NAND or SD version)[/URL] to create the partitions and format them. 3b If you rather use a computer for creating and formatting partitions keep in mind that both partitions [B]must[/B] be primary partitions (not logical) 4. The recommended size of your EXT4 partition is depending on how many roms and apps you are going to install.. 512M is the minimal size.. 5. Restore/move the sdcard contents back to the Fat32 partition 6. (WP7 users) make sure the EXT4 partition is located @ /dev/block/mmcblk0p2 To check this mount your sd-ext partition in 4EXT recovery and use adb shell or QtADB shell and type [B]df[/B] 7. Your sdcard is now ready for NativeSD usage..
NativeSD Installation for Magldr NAND Android & WP7 users :
Code:1. WP7 and SD users set your SD BOOT directory to the 'Recovery' folder by choosing '10.services' , '1. Bootsettings' , 3. AD SD Dir in the Magldr menu. 2. Boot into (NAND or SD) 4EXT recovery. 3. Flash the ROM.zip package and follow instructions 4. Set your SD BOOT directory to the 'NativeSD' folder after flashing the ROM (see step 1) 5. Boot into the ROM and have fun..
NativeSD Installation for cLK NAND Android users : (thanks clio94)
Code:1. Copy the [URL="http://www.mediafire.com/?nhyausx0p5whu"]flash_bootv2.zip[/URL] to your sdcard. 2. Boot into cLK and make a sboot partition.Be aware that only clk from kokotas allows to make a sboot partition directly from device 3. Boot into recovery (4EXT recovery = recommended) and install rom by choosing sd-ext method 4. After installation finishes,dont reboot, but install flash_sbootv2.zip and then reboot to cLK 5. In cLK choose to boot from sboot and wait for the ROM to boot. 6. If you are stuck on the boot animation,try to wipe your ext partition and install the ROM again.
NativeSD Installation for Windows Mobile and other OS users :
Code:1. Boot into recovery by executing the usual clcad and haret stuff inside the Recovery folder. 2. Flash the ROM.zip package and follow instructions 3. Reboot and boot the ROM by executing the usual clcad and haret stuff inside the NativeSD folder.
RMNET or PPP ??? summary :
Code:- as of dual installer v2 you can choose your data connection during ROM installation - For Magldr users I recommend using the RMNET connection - For all other users I recommend using the PPP connection (default) - PPP connection should work for all users !
Switch between different NativeSD ROMS ?
Code:- If you want to use a previously installed/other NativeSD ROM ? - Copy the contents of that roms folder found inside the NativeSD folder to the root of the NativeSD folder (overwriting the kernel+ramdisk) - Boot to sd and that ROM will boot ! - Repeat the above steps when you want to switch again - In the future we want to make the above steps easier and possible with either a 'gscript' or an 'android app'
Previous Roms (Examples) featuring NativeSD and Dual Installer :
Code:- [URL="http://d-h.st/pFR"]PA_v1.992se_dual_installer_v2.zip[/URL] - [B][URL="http://tinyw.in/Xhft"]mirror[/URL][/B] (Flash via recovery) - md5: ce2138748c6b2cbc62848272acf92600 - [URL="http://d-h.st/p33"]AOKP_N2408se_dual_installer.zip (Magldr only!)[/URL] - [B][URL="http://tinyw.in/clMS"]mirror[/URL][/B] (Flash via recovery) - md5: 6a116ad3eebb0f92729af6954f0a9217
*** all flashing is at your own risk ! Always make backups in recovery and/or titanium backup ! ***
*** This is a NativeSD thread ! Please, Keep this thread NativeSD related and report issues with roms in the rom thread !!! ***
Thanks & Credits to : securecrt, Phoenix, clio94, LNE team and everybody I forgot !68Q&A
- How is the NativeSD ROM work?
To boot the Android from SD card, the old SD ROMs mount the system.ext4 and data.ext4 before the init(rename to init.android) thread is start. I changed the initrd.gz to make it mount the ext4 partition before the android init.android start. here is the main code for the init script
Code:echo "mount system and data partition on sdcard" # change the rom_name TO PA MIUI CM7 will support # to boot other system on SD/EXT4 # the system layout : # /NativeSD/NexusHD2/ # /system # /data # /PA/ # /system # /data # /MIUI/ # /system # /data # /app # the app dir is shared for all ROMs # # set the name of the rom to boot rom_name="PA" # mount the 1st (NativeSD) SD-EXT partition mkdir -p /NativeSD mount -t ext4 -o rw,noatime,nodiratime,barrier=0 /dev/block/mmcblk0p2 /NativeSD # mount the system data app dir mount --bind /NativeSD/$rom_name/system /system mount --bind /NativeSD/$rom_name/data /data # create app data/app dir mkdir -p /NativeSD/app mkdir -p /data/app mount --bind /NativeSD/app /data/app
So for the ROM Devs should create new initrd.gz which is different with the NAND version, use different rom_name distinguish with others the whole templete is in 2nd post by Xylograph
- How is the multi-boot works on NativeSD ROM?
Set the SD boot dir /sdcard/NativeSD in Magldr or CLK,the dir structure is
/sdcard/NativeSD/NexusHD2/zImage
/sdcard/NativeSD/NexusHD2/initrd.gz
/sdcard/NativeSD/PA/zImage
/sdcard/NativeSD/PA/initrd.gz
/sdcard/NativeSD/zImage
/sdcard/NativeSD/initrd.gz
The Magldr& CLK always read the /sdcard/NativeSD/zImage /sdcard/NativeSD/initrd.gz files to boot, so if you want to switch from PA to NexusHD2 just only need to copy the zImage & initrd.gz to the up layer dir, use the NativeSD ROM switch app made by datagr
- How to convert the NAND ROM to NativeSD ROM?
This is for Devs and advanced users only. For example if we got the NAND version of the NexusHD2 extract the zip file and replace 2 files and add 1 file will finish the convert.
/kernel/boot/initrd.gz
the initrd.gz is similar with the SD ROMs but need to change the init script to mount the ext4 partition
/META-INF/com/google/android/updater-script
the updater-script is used for CWM to execute the install process; execute install.sh before copy the system content to the ext4, here is the sample code
Code:package_extract_file("install.sh", "/tmp/install.sh"); set_perm(0,0, 0777, "/tmp/install.sh"); run_program("/tmp/install.sh"); show_progress(0.8, 80); if file_getprop("/tmp/nfo.prop","NativeSD") == "true" then package_extract_dir("kernel/boot", "/boot"); package_extract_dir("kernel/boot", "/boot_dir"); package_extract_dir("system", "/system"); ...... else ui_print("can't find ext4 partition on your SDcard"); ui_print("install failed"); endif;
/install.sh
Code:#!/sbin/sh # Set the ROM name ROM_NAME=NexusHD2 export ROM_NAME mmcblk0p2=`ls /dev/block/mmcblk0p2` # Mount the ext4 partition if [ $mmcblk0p2 == "/dev/block/mmcblk0p2" ] then mkdir -p /ext4p mkdir -p /sdcard/NativeSD/$ROM_NAME mkdir -p /boot /boot_dir mount -t ext4 /dev/block/mmcblk0p2 /ext4p mkdir -p /ext4p/$ROM_NAME/system /ext4p/$ROM_NAME/data mount --bind /ext4p/$ROM_NAME/system /system mount --bind /ext4p/$ROM_NAME/data /data mount --bind /sdcard/NativeSD/$ROM_NAME /boot mount --bind /sdcard/NativeSD /boot_dir #delete the old system rm -rf /system/* #clean the dalvik-cache rm -rf /data/dalvik-cache/* #all the dir has ready write some info for updater-script echo "NativeSD=true" >> /tmp/nfo.prop else #no ext4 partition found echo "NativeSD=false" >> /tmp/nfo.prop fi
- How to make ext4 partition on my SDCARD?
62nativeSDMultiBoot Version 10
Hello all,
Here is the latest version 10 of the app.
Change log :
----------------------------------------------------------------------------------------------------------------------------------------
Version 10 :
Fixed : Small aesthetic changes
Added : Website button
Added : Backup nativeSD rom
Added : Restore nativeSD rom
To backup a rom, click [Backup rom] then click a rom that you wish to backup.
The app will create sdcard/RomBackups/toEXT4/rom_name/rom_name.ext4.tar
and sdcard/romBackups/toSD/rom_name.ext4.tar files.
These are your backup that you can save them anywhere before you do any tests.
To restore a backed up rom, click [Backup rom] then click [Restore].
You will see that the app is switched in [RESTORE MODE].
In [RESTORE MODE] click a rom that you see in the list.
(Note that you must NOT change anything in sdcard/RomBackups folder.
If you changed anything from there then you must put the files and folders as they were,
before you enter again in the app and restore or backup any rom.)
PLEASE READ THIS :
You must NOT touch the app while backup or restore operations.
It will be unresponsive during the operations
(You can use a debugger to see what is the app compressing or decompressing).
Enjoy the app and please hit the thanks button (yes, it's still free!)
----------------------------------------------------------------------------------------------------------------------------------------
Version 9 :
Changed : no need the rom_name.txt method anymore. (requested by Tytung)
Added : Thanks to the guidance from securecrt now the app is getting the name through linux shell command.
Changed : colored text to [Switch rom] section. Blue color means the current running rom.
Added: Tabs in switch and delete sections for bigger buttons and more beautiful interface.
Changed : improved performance of the app (I hope it's ok now Szczepanik )
----------------------------------------------------------------------------------------------------------------------------------------
Version 8 :
Fixed : [Delete rom] section that was messed up from a bug that I found and now it is ok.
Added : colored text to [Switch rom] section. Cyan color means the current running rom(or the latest clicked rom).
Added : rom name in the [Tools] section so you will know in which rom the changes will be applied.
----------------------------------------------------------------------------------------------------------------------------------------
Version 7 :
App supports switching and deleting up to 18 nativeSD roms.
App will read from /proc/self/mountinfo the rom name and compare it with the rom_name.txt
that is automatically created in sdcard/nativeSD folder.
If the name matches, then it will enable the [Delete] and [Tools] buttons.
If not it will hide those 2 buttons to avoid any mistakes.
Also some small bugs have been fixed from previous versions.
----------------------------------------------------------------------------------------------------------------------------------------
Version 6 :
Added : fix permissions in nativeSD roms
Added : clear Dalvik cache in nativeSD roms
Added : kernel update(*) for nativeSD ONLY roms (thank you master Tytung for the guidance)
(*) How to update kernel :
1) Download the zip file of the kernel (tytung 3.5 and securecrt 24Sep2012 kernels work perfect)
2) Rename it to [update.zip] and put it in the sdcard/nativeSD folder
3) Run the nativeSDmultiboot app and click [Switch] -> click your current running rom -> [Back] -> [Tools] -> [Update kernel]
4) Reboot IMMEDIATELY! (this is really important to avoid any force closes...)
----------------------------------------------------------------------------------------------------------------------------------------
Version 5 :
Now CLK users can use this app to switch roms! (You must put [mkbootimg.sh] and [mkbootimg]
from [flash_sboot_v2.zip] inside the folder sdcard/nativeSD/)
The interface has been changed also.
----------------------------------------------------------------------------------------------------------------------------------------
Version 4 :
On first enter please click on the rom that you are running now! THIS IS VERY IMPORTANT!
It will create a rom_name.txt inside the nativeSD folder with the name that you are running (thanks for idea securecrt).
I have also added the delete function with confirmation message (requested by Xylograph).
It will hide the rom that you are currently running to avoid any mistakes (requested by securecrt).
P.S. All fellows developers are free to include it in your nativeSD roms.58Hello all,
Please download version 10 with latest updates.
