Leider bin ich dem englisch nicht mehr so mächtig. Naja, mit fast 50Jahren darf man das auch mal vergessen
Würde das bitte mal jemand übersetzen?
This guide will allow you to dual boot your phone between two ROMs.
Thanks for the original method to:
Guys on the Blade forum - especially android@sam
The way it works:
One ROM is flashed as normal onto the NAND of the phone (referred to as the "NAND ROM" in the guide)
One ROM uses two specially created partitions in the sdcard to boot the system (referred to as the "SD ROM" in the guide)
Two script files which can be run from the ROMs allow you to switch between the two.
The Guide:
Download your two ROMs - one of them will have to be a ROM in the second post. The other one can be anything. Support for more ROMs will be added in the future.
Download the required updater-script and bootsd.img files from the second post as well as the generic scripts.zip.
Make a copy of the downloaded bootsd.img and rename it boot.img.
In the SD card ROM - open with an archive manager - eg 7-zip - and replace the boot.img with the one from the above step - just drag and drop the file into the archive.
In the same manner as the above step, inside the archive, navigate to META-INF/com/google/android and replace the updater-script with the downloaded one.
Connect your phone to the computer and mount USB mass storage.
Make a backup of your SD card (IMPORTANT but optional).
Download and install a disk editor (eg. EaseUS partition master for Windows or gParted for Linux).
Load up the partition editor and make sure you can see your phone and are working with it - BE CAREFUL THAT YOU ARE NOT ERASING/MESSING WITH A HARD DISK IN THE NEXT STEP.
Get rid of all the existing partitons.
Create a primary FAT32 partiton leaving 500MB free space at the end.
Create a primary EXT3 partiton of 250 MB.
Repeat the above step,
Apply the changes. So, the disk should have a primary FAT32 partition and two, primary 250MB EXT3 partitions.
Restore your backup of the SD card and copy the modified SD card ROM and the non-modified NAND ROM to the SD card.
Extract the scripts ZIP and rename it "multiboot".
Extract the boot.img from the NAND ROM and copy it into the "multiboot" folder, naming it "bootnand.img"
Copy the earlier download bootsd.img into the "multiboot" folder
Copy the enitre multiboot folder into the root of the SD card
Reboot into recovery
Wipe data/factory reset the phone
Install the NAND ROM
Install the SD card ROM
Reboot into system
Your SD card ROM should now load up - you are done!
NOTE: If you are using a CM ROM you will also need to perform the updater script replacement for GAPPs as well before installing GAPPs. An updater-script for JB GAPPs is provided on the second post.
Switching between ROMs:
Your ROM needs to be rooted for this to work!
Download and install terminal emulator from the market
Type:
su
cd /sdcard/multiboot
Type either:
sh bootsd.sh - to boot into SD card ROM
sh bootnand.sh - to boot into NAND ROM
