SDCard Boot for Micromax A116

This project is discontinued as I have bought a Galaxy Note 2. This project is open to anyone who wants to take over.

Announcement:Full developer support would be provided for tutorials and user-scripts.





What is SDCard boot?

SDCard boot means Installing the ROM on the SD-Card instead of the EMMC and leaving the EMMC empty for other ROMS.

How is it useful?

It is useful if you need to test roms that don't fit on the EMMC and also enables the user to keep multiple roms on multiple sdcards.

Instructions
Prepare ROM ZIP
Download all the files from the Second Post and follow the instructions given for your ROM

1. Partition SD Card
   • Partition 1 : FAT (/sdcard)
   • Partition 2 : EXT4 (/system)
   • Partition 3 : EXT4 (/data)
   • Partition 4 : EXT4 (/cache)
2. Flash SD-Recovery.img (See attachments)(Use MobileUncle Tools. It is easier to switch to EMMC Boot or Dual Boot.)
3. Flash ROM (From SD-Recovery)(See 2nd post for a list of compatible ROM and Instructions for installation)

Multi/Dual Booting

NOTE: This feature is not stable yet, may not work on some roms and will remove recovery mode from the device.

Prepare your phone for MultiBooting
-Flash normal CWM/TWRP Recovery
-Install the ROM (EMMC) normally
-Copy boot.img from ROM.ZIP to '/sdcard/boot/emmc/' and '/emmc/boot/emmc/'
-Flash TWRP SBDooT
-Reboot to Recovery
-Flash the ROM you want on the sdcard (ROMS in Sencond post)
-Copy boot.img from SD ROM.ZIP to /sdcard/boot/sdb and emmc/boot/sdb
-Flash mBoot.zip

BUGS
Boot Menu Flickering.

Make sure that the EMMC ROM boot.img mounts "/dev/bootimg" and /dev/recovery"(optional) or SD ROM won't boot.

Convert ROMS from EMMC to SD

1.Obtain the target boot.img
2.Unpack using unpack-MT65xx.pl

Code:

./unpack-MT65xx.pl boot.img

3. Open the fstab file
4.Change the following

Code:

/emmc@cache
/emmc@usrdata
/emmc@android

to

Code:

/dev/block/mmcblk1p4
/dev/block/mmcblk1p3
/dev/block/mmcblk1p2

5.

Code:

repack-MT65xx.pl -boot boot.img-kernel.img boot.img-ramdisk SDBoot.img

6.Flash SDBoot.img as Boot.img
7.Share it on XDA

Future Support(Developers)

• Use "/system" instead of "emmc@android" on updater script
• Add an option for your own mBoot.img to make it easier for others to flash on sd/emmc
• Add the following line at the end of fstab.mt6589 on mBoot.img
  Code:

  /dev/recovery /recovery emmc defaults

Try using the script with Cygwin. I will upload more soon.
NOTE: Installation to internal memory doesn't require any modification to boot img.

I am first focusing on get mBooT stable then I will upload other mBoot.img files. Some of the early mboots will be :
Lewa
Stock(This will work on most of the stock based 4.2.x roms)
MIUI
Custom Kernel(Not Sure which one) with Stock Ramdisk.

So I'll need to make 4 partitions on my external SD card,right?
1 FAT and 3 EXT4.
What sizes should I make the EXT4 partitions?
I currently have a 32gb card with 25gb FAT and remaining EXT3 because I use Link2SD

EDIT: I want to use the CM11 along side my existing stock 4.2.1, and currently have 6.0.4.8 Phil's Touch recovery......can you explain me the steps to multiboot with the CM11? I already have the Mobile Uncle tools and I am familiar with using it.

You will have to Partition you SD-Card as given in first post or SDBooT wil not work.
You need Init.d Support on both of the roms (Stock may not work) Try Colossus Rom

Instructuions:
Required Software:
7zip
Notepad++

Preparing EMMC ROM:
-Install Colosus Rom via any recovery
-Create a new folder on your sdcard. call it boot
-Inside Boot, create another folder called 'emmc'
-Extract the boot.img from Stock ROM
-Copy Colossus Boot.img to /emmc

Preparing SDBooT
-Download and Install twrp-sd-recovery that is attached in the 1st Post
-Download CM11 and all the required patches
-Extract META-INF/google/updater-script from CM11.zip
-Open updater-script in Notepad++
-Ctrl+F
-Switch to the Replace tab
-Find what : /emmc@android
-Replace with /dev/block/mmcblk1p2
-Ctrl+S
-Put the updater-script back in CM11.zip/META-INF/google/
-Download mboot.img from the first post
-Rename it to boot.img
-Create a folder inside the boot folder(that we created earlier) and name it 'sdb'
-Place this boot.img in 'sdb' and in CM11.zip
-Flash this via twrp-sd-recovery
-Flash all the CM11 patches via twrp-sd-recover without any changes
-Download mBoot.zip from the first post
-Flash it via any recovery.

Copy boot folder to Internal Storage and FAT Partition of SDCARD

-Structure (Placemant of boot folder and files in boot folder)

Code:

On Internal Storage
1.EMMC ROM
boot/emmc/boot.img
2.SDBooT ROM
boot/sdb/boot.img

On SDCard
1.EMMC ROM
boot/emmc/boot.img
2.SDBooT ROM
boot/sdb/boot.img

NOTE:If mBoot.zip fails to fire up at boot..
Workaround:
Perform this step at the end
Flash mBoot.zip via any normal recovery

Code:

On Internal Storage
1.EMMC ROM
boot/emmc/boot.img
2.SDBooT ROM
boot/sdb/boot.img

On SDCard
1.EMMC ROM
boot/emmc/boot.img
2.SDBooT ROM
boot/sdb/boot.img

This we have to do on the FAT partitions of both the storages,right?

I am still a bit unclear on the number and sizes of partitions on the SD card. I have finished making changes to the CM11 ROM zip and also installed an init.d emulator on my stock as I could not find a ROM that didnt require a complete factory reset. Sorry,I know I am asking too many questions,just trying to have all the knowledge before starting it.

TWRP stops working

I flashed the sd TWRP via Mobile uncle tools,when I boot into recovery, it just gets stuck at the 'Team Win' logo and doesn't respond to any touch or key press. Is it possible to install Dual boot with the regular CWM,or is it necessary to use the sd TWRP?
