Booting from sdcard

Necessary files

Download the file BootManager.zip.

How To

This package is intended for use on a rooted HTC Desire Z aka T-Mobile G2 aka HTC Vision only.

Using it on any other phone might brick it as the boot partition or some other partition will be overwritten.

It will allow you to put a bootable ROM onto your SD card and boot from it.

This is useful when partitions like /system or /data are not accessable or mountable any more.

ATTENTION: USE THIS PACKAGE ON YOUR OWN RISK, IT MIGHT BRICK YOUR PHONE.

IF POSSIBLE MAKE A FULL BACKUP OF ALL PARTITIONS USING RECOVERY.

This package contains CyanogenMod 7.1 configured to boot from SD card.

Extract the zip file and copy its content to your SD card.

Bootable system files are now on the SD card in the directory BootManager/rom8 in the root of the sdcard.

Make sure that no PC10.... whatever ... file is in the root of your SD card.

* Insert your SD card into your phone (do not connect usb cable).
* Boot into hboot mode by holding POWER + VOLUME DOWN about 5 seconds until your phone boots.
* Use VOLUME DOWN to navigate to "FASTBOOT".
* Use POWER button to select "FASTBOOT".
* Connect phone and computer using an USB data cable
* Your phone is now in fastboot mode and shows the red message "FASTBOOT USB"

You can now boot from SD card using the following command from your platform-tools folder of the Android SDK:

(If you don't have a fastboot executable you can find one for your operating system in the attachments of vision_utilities, where fastboot.exe is for windows and fastboot is for linux.

   fastboot boot boot.img

Phone should boot into and run CyanogenMod 7.1
