Data2Ext for A75



As you all know that Data2Ext is able to give huge boost to internal memory.
Till now it was working with ics rom by sagarwep only.
That script didn't work on other roms, I tested it on 2-3 roms myself.

Now, good news for you all is I have ported this script for A75 and its working perfectly.

Tested on stock rom but should work on all roms provided they have same partition table.

Working on following Roms:

1) Stock
2) BlueTerror 1.0 by aayushdutta
3) ICS 2.0 by sagarwep

How to Install (For Normal Users):

First of all, Back up your current rom

Step-1:
1) Install Link2Sd
2) Open it n create mount script for ext2
3) Reboot the device n open link2sd
4) Check whether 2nd partition is mounted (Storage info)
5) If yes, then proceed to Step-2

OR

1) Download MountScript_A75_by_Mastermind.zip from below & dump it to sdcard root
2) Reboot to recovery & Install zip from sdcard
3) Reboot system
4) Open Terminal Emulator in phone OR adb shell from PC
5) Apply command "cat /proc/mounts" & then "cat /proc/filesystems" without quotes
6) In mount command you should see "/dev/block/mmcblk0p2"
7) And in filesystems it should show ext2 at the end
8) If you get these responses then proceed to Step-2
9) If no, then open RootExplorer, Go to /data and create a folder named sdext2
10) Reboot n check again, it should mount sdext now
11) Proceed to Step-2

Step-2:
1) Download flashable zip file Data2ext_A75_by_Mastermind.zip
2) Dump that zip to root of sdcard
3) Reboot into recovery (CWM recovery)
4) Install zip from sdcard
5) When shows Install Complete, Reboot system.

Manual Method of Installation (For Advanced Users):

Get both my flashable zips n extract them.

1) First from MountScript zip,
- Get install-recovery.sh n put it in /system/etc/ and permissions to 755(rwxr-xr-x) or 777(rwxrwxrwx) and ownership to 0-root, 0-root
- Then ext2.ko module to /system/lib/modules/ n permissions rw-r--r-- & ownership to 0-root, 0-root
- Now go to /data n create a folder named sdext2
- Reboot
- Check whether 2nd partition is mounted or not.
- After successfull mounting only go to step-2

2) from Data2Ext zip,
- Get busybox_d2sd n put in /system/xbin/ n permissions rwxr-xr-x & ownership to 0-root, 2000-shell
- Get e2fsck n put in /system/bin/ n permisions to rwxr-xr-x & ownership to 0-root, 2000-shell
- Get all init.d scripts n put them in /system/etc/init.d/ n permission for all to 777 that is rwxrwxrwx & ownership to 0-root, 0-root
- Reboot

Caution:
Preferably you should flash this after a factory reset but should work without reset too.
Best work after factory reset.If u have tried script already n didn't work,n u want to giva a try again after factory reset then please remove 02data2ext script from /system/etc/init.d/ first...n ya, backup ur imp data...

Download:
1) MountScript_A75_by_Mastermind.zip (Contains mount script and ext2 module)
2) Data2ext_A75_by_Mastermind.zip (Contains data2ext script & necessary binaries)
3) Stock rom boot.img with init.d support by Mastermind

Credits:
-Lenovo A60 devs for that great ics rom with data2ext script
-Sagarwep for bringing that rom to A75
-Shahabazas for letting us know about the script
-ME for porting the script to A75 stock rom

Additional Notes:
-You may receive some force close errors on 1st boot, its normal, just give the rom some time n reboot, u will be fine.

Disclaimer:
I am not responsible for bricked devices, dead SD cards, thermonuclear war, or you getting fired because the alarm app failed. Please do some research if you have any concerns before flashing! YOU are choosing to make these modifications, and if you point the finger at me for messing up your device, I will laugh at you.

1) On Stock rom

2) On BlueTerror 1.0 by aayushdutta

3) On ICS 2.0 by sagarwep

I have installed LegoIce II ROM on my microamx a75, working good, and have data2ext script, my internal memory is 1gb now, though some of apps can't be installed from my back up, just need to know that, when installing any apps where should I install it, on internal storage or external. Till now I always tick the Automatic, but what would be correct place to store?
one more thing, can this be used along with Link2sd? as my partition generated by CWM is ext3 type, but link2sd says mountscript can not be generated because my device does not support ext3, go for FAT32.
Thanks in advance.

Hey Frnds How r u...
I want to help u all for for increasing int memory...
First of all root your micromax A75 phone so that its easy for incresing internal mem
***plz ROOT A75 in this process-- www.techclap.com/9656/rooting-micromax-a85-a75-superfone-tutorial/

important- download android-sdk bundle from developer.android.com/sdk/index.html

Then download these small files
1. mountscript

2. data2ext

3. int2ext+deodexed

4. after root script folder

follow below steps to increse memory
1-u need memory card of class 6 or higher for better result. use card reader & plug it to pc.

2-use minitool partition wizard to first make primary,fat32 partition for ur data storage then ext2 partition of 1GB(primary, ext2)
[its important to first make ur fat32 partition then ext2 partition of 1GB ]

3- Install Link2SD then power off phone, goto recovery(by pressing power buton with vol+ key together) & install mountscript_mastermind.zip (by install zip from sdcard)then reboot.

4- GOTO LINK2SD allow superuser then choose ext2 type partition.

5- then reboot & check if ext2 is mounted or not, if not mounted then repeat process from starting step 1(to check if mounted or not open link2sd > storage info)

6- if mounted then goto recovery install data2ext_mastermind.zip then goto mount & storage > format sd-ext(in that recovery mode) & then reboot.

7- then execute run_me.bat from "after root script" folder & complete the whole process as per instructions then check if internal memory increased or not. (for this step u must have android-sdk installed & updated latest drivers in ur pc)

8- after it goto recovery to install INT2EXT+deodexed_Mastermind.zip, then reboot
congrats process finished

N.B :- when mount error appear just quick reboot & phone is ready

To all guys who dont see JustBeatIt file in /data
I think ur boot.img does not have init.d support or 2nd thing can be u guys have not installed Busybox on ur device...
Use varun' boot.img or my boot.img from Method to Root Mmx A75 sticky thread in All-Things-Root section, I m using mine img,it also initializes ext2 module on boot, i hv busybox latest n 2nd partition of approx 1gb.

All guys who r not on stock, please don't just flash either varun's or mine boot.img because ICS by sagarwep n SilverLight are port n not modified stock so their respective developer may have changed bootclasspath in boot.img, so wrong bootpathclass will lead to softbrick or bootloop.
So get me ur respective rom's boot.img, I will check whether it has init.d support n will make necessary changes for data2ext n provide in OP.

N when u provide me outputs of cat commands please mention ur rom before it.

@kujang
Ur device has ext2 support n also mounted 2nd partition..1st check the above pre-requisites I hv mentioned, if any of them is lacking then u will not get working data2ext.n mention ur rom.I will check the script n let u know if smthin has 2 bb change,can't do it now,m on mobile.

Thanks.

whenever i flash the boot.img provided by u my screen becomes white.. and with my stock boot.img i m not able to make either of data2ext or int2ext work. so i m attaching my boot.img please mod it and send me. thanks in advance.
