Chainfire 3d is for older android version 2.3 only. It has not been updated to work in jelly bean 4.2, so do not install it. Better reflash the ROM and write imei using IMEI write tool given in 1st post.

Select the Framroot 1.6.1.apk in the below link from your opera mini browser select save select open and select install.

Thanks Alephzain

In Framaroot → select Boromir. After success message reboot your phone.

Now you have Root access.

2. Install Busybox

Go to Playstore and Install Busybox by Stephen (Stericson)

Open Busybox give root permission when prompted.
Wait for few minutes to complete smart install analysis, then select install then select smart install without making any changes.

Busybox is needed for executing modifying commands.

3. Increasing Internal Memory for installing more apps

Make 2 partitions in your SD Card as primary partitions using minitool partition wizard in windows / gparted in linux (be careful to change only sd card and not computer partition)

1st as FAT32 (primary) for storing DATA, Music, Videos etc.,. (say 6.5 GB in 8GB SD Card)
2nd as FAT32 or ext4 (as primary) for linking apps with link2sd balance memory in sd card (note: kernel supports ext partitions)

You can also resize partition. See link below on how to partition
http://forum.xda-developers.com/show....php?t=2142844

Thanks bakpinar and sanny5

Install Link2SD from Play store → select Fat16/32

→ if it says mount script created. You can link your apps to 2nd partition through link2sd.

→ If it says mount: no such file or directory
Install Mount /System (rw / ro) from play store → Select Mount R/W
Install ES File Explorer → copy the below script in notepad++ in windows (not notepad, google it) or gedit in linux or if you want to use your phone install droideditfree and save as install-recovery.sh and copy the file to the folder /system/etc/ after enabling mount r/w as said above
--------------------------------------------------------------------------------------------
#!/system/bin/sh
# mount vfat 2nd partition from sd card
sleep 2
mount -t vfat -o rw /dev/block/vold/179:2 /data/sdext2
mount -t vfat -o rw /dev/block/mmcblk0p2 /data/sdext2
---------------------------------------------------------------------------------------------
Note : Replace vfat with ext4 in the above script if you want to use ext4 partition.

Read the above script horizontally in phone.
Thanks to Kierrok

Permission setting for the above file -> after copying long press the above file in ES file Explorer -> select more -> select properties -> select change under permissions -> tick all the read, write and execute except write by others.

Reboot phone. Link2sd will work now.

4. Increasing RAM (SWAP)

The phone already has 190Mb internal swap. It is too low.

Install Swapper for Root → put value 756 → select active at boot. Class 10 sd card will work better.

You can also further increase SD Card speed with installing SD Speed Increase → setting kbs based on class of sdcard to maximum
and set on every boot.

Now we have overcome the twin limitations of LAVA IRIS 402 to some extent.

Dear sir,

I wish to start with my thanks about your internal memory upgrading blog.

I have purchased new Lava 402 Smart Phone. I am getting message as "the phone storage does not have enough space. please release some storage or change the default write disk in the settings" while using camera. But I checked in my mobile settings, there is no option to change the default memory settings to write in SD Card. Please help to come over from this issue.

I didn't had any problem with camera. It is storing images to SD card only. Has your SD card detected ? Re insert card properly after switch off. If this also not works try installing any other camera app from play store.

Thanks oppili,

I have installed new camera app (Zoom Camera)from play store. It works.

But default camera (which is come with IRIS402) stores image/video only internal memory not to sd card.

If any setting inside, please tell me.


Thanks alot.

I have a Lava Iris 402.. Link2SD fails to detect the second partition in both cases (FAT32/ext4). Any solution??

Copy pasted the script in /system/etc. Link2SD still doesnt detect 2nd partition.

Have you set the permission for the copied file as explained ? It should work if it is done.

If you had done as explained it should work. It takes initially a minute to boot after the script copying, can you wait & check if it is OK.

Set the permissions as mentioned in the OP. Ticked all Read, Write & Execute, except Write (Other). Is that correct?
