There are moments in our Android lives when we can’t decide which ROM to choose. Each one has its own advantages and disadvantages like bugs, features, and so on. If you have only one device, you can swap around ROMs in the recovery. Unfortunately, that’s not a perfect solution, as it’s time consuming and wipes data every time. Luckily, there is another way.
We’ve covered Multiboot by XDA Recognized Developer Tasssadar several times in the past. The developer has now updated this amazing tool to work with the Nexus 5, enabling the hammerhead to join the Nexus 4 and Nexus 7.
Most multiboot solutions require modifications to the device’s bootloader, or at the very least, it’s /system partition. The method presented by Tasssadar is totally different. The whole tool is split into three parts: a kernel, recovery, and MultiROM application. When the device boots, MultiROM displays a window that allows you to select which ROM to start. Your current ROM is not erased, and no data will be lost. The modified TWRP recovery allows you to update any of the installed ROMs without problems. ROMs can even boot from external USB drives by using a USB-OTG cable
Since the last release, many new features have been added. Tasssadar was kind enough to explain few of main features of his project:
- “Swap ROMs” feature – the user can now swap any of the secondary ROMs with the primary one.
- “Run last booted ROM” auto-boot type – previously, the user only had option to set ROM X to boot after N seconds, now he can set it to boot the ROM he selected last after N seconds too.
- Support for OTAs on secondary ROMs – tested with omnirom, CM won’t work because it doesn’t use TWRP and Stock OTAs will never work with rooted & modified devices.
- Support using different radios for each ROM on N4 and N5, this fixes problem with N4’s kitkat radio which is not compatible with Jellybean ROMs.
- Bunch of random fixes.
