[Galaxy Grand Duos i9082 General] k2wl:
Hi guys

today i am gonna guide you to increase internal storage of galaxy grand.

so first you need following things.

1. patience

2. computer with adb enabled.

3. galaxy grand i9082 with CWM or Philz or TWRP installed.

This procedure will wipe out your whole internal partition. means your all data on internal storage will be gone.

So make back up first.

This is dangerous procedure. needs advance knowledge.

1. So, first boot into recovery.

i think you guys know how to do that.

2. Connect PC and mobile

3. open terminal/CMD on PC/linux computer.

4. type following

adb shell

5. Type

cd /dev/block
parted mmcblk0
print

6. This looks like following

print

Model: MMC M8G1WA (sd/mmc)
Disk /dev/block/mmcblk0: 7818MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt

Number Start End Size File system Name Flags
1 14.7MB 15.7MB 1049kB cal
2 15.7MB 16.0MB 262kB sysparm_dep
3 16.0MB 16.3MB 262kB parm-spml_dep
4 16.3MB 16.5MB 262kB RF_CAL_FILE
5 16.5MB 24.9MB 8389kB KERNEL
6 24.9MB 33.3MB 8389kB RECOVERY
7 33.3MB 53.0MB 19.7MB modem
8 53.0MB 86.2MB 33.3MB reserved
9 86.2MB 88.3MB 2097kB SBL1
10 88.3MB 90.4MB 2097kB SBL2
11 90.4MB 98.8MB 8389kB PARAM
12 98.8MB 99.4MB 524kB DTSBK
13 99.4MB 99.9MB 524kB DTS
14 99.9MB 108MB 8389kB VC-FirmwareBK
15 108MB 117MB 8389kB VC-Firmware
16 117MB 117MB 262kB FOTA_SIG
17 117MB 138MB 21.0MB ext4 efs
18 138MB 1212MB 1074MB ext4 CSC
19 1212MB 2822MB 1611MB ext4 system
20 2822MB 3409MB 587MB ext4 HIDDEN
21 3409MB 7813MB 4404MB ext4 data

7. last 4 partitions i.e number 18,19,20, 21 will be erased and repartitioned again.

this is dangerous step. dont do it. if you dont understand what you doing.

8. type following

rm 21
rm 20
rm 19
rm 18

9. Now we will create new partitions as we wanted. copy following cammands one by one followed by ENTER.

mkpartfs primary ext2 138 538
mkpartfs primary ext2 538 1638
mkpartfs primary ext2 1638 1838
mkpartfs primary ext2 1838 7813
quit

10. after last "QUIT" command it wil say.

quit
Information: You may need to update /etc/fstab.

Ignore the warning Reboot into recovery again on pc type

11.

adb shell
mke2fs /dev/block/mmcblk0p18
tune2fs -j /dev/block/mmcblk0p18
mke2fs /dev/block/mmcblk0p19
tune2fs -j /dev/block/mmcblk0p19
mke2fs /dev/block/mmcblk0p20
tune2fs -j /dev/block/mmcblk0p20
mke2fs /dev/block/mmcblk0p21
tune2fs -j /dev/block/mmcblk0p21

This will create ext3 partition from ext2

Now convert them to ext4

12.

tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p18
tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p19
tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p20
tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p21

Now lets check everything is ok

13.

cd /dev/block
parted mmcblk0
print

This should look like following

14.

Number Start End Size File system Name Flags
1 14.7MB 15.7MB 1049kB cal
2 15.7MB 16.0MB 262kB sysparm_dep
3 16.0MB 16.3MB 262kB parm-spml_dep
4 16.3MB 16.5MB 262kB RF_CAL_FILE
5 16.5MB 24.9MB 8389kB KERNEL
6 24.9MB 33.3MB 8389kB RECOVERY
7 33.3MB 53.0MB 19.7MB modem
8 53.0MB 86.2MB 33.3MB reserved
9 86.2MB 88.3MB 2097kB SBL1
10 88.3MB 90.4MB 2097kB SBL2
11 90.4MB 98.8MB 8389kB PARAM
12 98.8MB 99.4MB 524kB DTSBK
13 99.4MB 99.9MB 524kB DTS
14 99.9MB 108MB 8389kB VC-FirmwareBK
15 108MB 117MB 8389kB VC-Firmware
16 117MB 117MB 262kB FOTA_SIG
17 117MB 138MB 21.0MB ext4 efs
18 138MB 538MB 400MB ext4
19 538MB 1638MB 1100MB ext4
20 1638MB 1838MB 200MB ext4
21 1838MB 7813MB 5975MB ext4
