Information On Dual Booting Roms

Since we currently have an issue with the network radio on our CM10 roms, most people will not be able to use this rom as a daily driver, and would prefer to stay on a fully functioning GB rom. This dual booting method lets us have the best of both worlds! You can have a buttery smooth and fast CM10 rom for enjoying all of Android Jellybean 4.2.1 goodies and a fully function Gingerbread rom when ever you need to make a call and such. For now, this is the best we can do. It's simple and very fast to switch between roms. What else could you ask for? ;D

Installation Instructions Including Dual Booting

DISCLAIMER

I (WE) AM NOT RESPONSIBLE of any damages to your device related to the use of this ROM or the dualboot toolkit. You do this at your own risk. Even though this has been tested and works well, using NVFLASH may brick your device if done incorrectly.

This ROM comes in two flavours: The dualboot toolkit or the Original flashable ROM

Dualboot ROM Instructions

WARNING! NVFLASH will format EVERYTHING, including internalSD. Make sure you backup your important files on your externalSD card

PART 1 - Resizing system partition

1) Unzip the dualboot toolkit and unzip NVFLASH_Resizer-G2X.zip.

2) Power off your phone and remove the battery. Keep vol. up and vol. down held and plug the phone via USB to a WINDOWS computer.

3) Windows should add an "APX driver". Go to control panel -> Device manager and right click on it -> Update driver -> search in system. Then, browse to the drivers folder inside the NVFLASH package and choose nvidiausb.inf. Approve any error messages (Windows 8 users read my FAQ). Install the Nvidia Fastboot driver.

4) Unplug your phone and hold down vol.up and vol.down. Replug it again and double click on flash.bat inside the NVFLASH folder. KEEP BOTH BUTTONS HELD DOWN DURING THE WHOLE PROCESS!.

5) When NVFLASH is done, unplug the phone and put back the battery. Reboot into recovery with power + vol. down. Plug it back and go to mounts and storage -> mount USB storage. If your PC asks to format the internal SD card, select yes.​

PART 2 - Installing ROMS

1) Download the desired "call/SMS" ROM and extract boot.img from it's flashable zip. Rename it to boot1.img. Extract Step3_bootimg.zip from the dualboot toolkit and copy-paste boot1.img into system/boot, replacing the file that is already there. Repack Step3_bootimg.zip.

2) Copy-paste your desired ROM into the 0dualboot folder and send it to your device SDcard with everything it contains (your device should already be in the "mount USB storage" menu).

3) From the recovery, flash Step1_enabler.zip. When the screen goes black, hold power + vol. down to get back into recovery.

4) Flash your desired ROM, then Step2_ROM1.zip. Reboot to the OS.

5) You should have a Systemchanger app. Open it, click on "Switching" and give root permissions. When the screen goes black (again...), hold power + vol. down to get into recovery.

6) Flash ROM2.zip and Step3_Bootimg.zip and reboot in the OS

And there you go! To switch from one OS to another, just open the systemchanger app and click on "switching"!

Credits to bihariel for the original method. See the original thread here.​

Original flashable zip ROM instructions

1) Boot into recovery with power + vol. down

2) Wipe data/cache, then mounts and storage -> format system

3) Flash this ROM

4) Advanced -> Wipe dalvik cache and fix permissions

5) Reboot and enjoy!​

Special trick : In settings, go to About phone and click 6 times on Build number. This will pop up the developer and performances options. In performances options, CPU settings, change the governor from INTERACTIVE to SMARTASSV2.
