MultiROM is one-of-a-kind multi-boot mod for Galaxy S4. It can boot any Android ROM as well as other systems like Ubuntu Touch, once they are ported to that device. Besides booting from device's internal memory, MultiROM can boot from external SD card. The main part of MultiROM is a boot manager, which appears every time your device starts and lets you choose ROM to boot. You can see how it looks on the image above. ROMs are installed and managed via modified TWRP recovery. You can use standard ZIP files to install secondary Android ROMs and MultiROM even has its own installer system, which can be used to ship other Linux-based systems.
DISCLAIMER: You take responsibility of your phone and what you flash into it, not me. You are warned!
* Multiboot any number of Android ROMs
* Restore nandroid backup as secondary ROM
* Boot from Internal memory and MicroSD Card
And since i don't feel like ripping this stuff from AntaresOne's thread, go read it here (i'm lazy): http://forum.xda-developers.com/gala...m-v28-t2864469
This is basically the same, i've done some small modifications and development to get it working on I9295.
1. Via MultiROM Manager app NOT tested on I9295, propably won't work. Don't try! (But if you do, report )
2. Manual installation
Firstly, there are videos on youtube. If you want, just search for "MultiROM installation" on youtube and watch those, big thanks to all who made them. There is also an awesome article on Linux Journal.
Note 1: Your device must not be encrypted (hint: if you don't know what it is, then it is not encrypted).
MultiROM has 3 parts you need to install:
MultiROM - download the ZIP file and flash it in recovery.
Modified recovery - download the ZIP file and flash it in recovery or Mobile Odin app to flash the recovery.img contained inside ZIP.
Patched kernel - Download the ZIP file and flash it in recovery or keep stock kernel (CM11/based ROMs with this android_kernel_samsung_jf source)
You current rom will not be erased by the installation.
Download links are in the second post.
MultiROM TWRP can work without MultiROM installed. Obviously most MultiROM related features won't work so steer away from them.
When formatting partitions, especially /data, do keep backups handly, even from /sdcard. As /data and /sdcard are on same partition, formatting /data formats /sdcard. Note that factory reset doesn't actually format /data, it just wipes the directory clean. But when changing fs type on /data, /sdcard will be formatted also.
