Hello!!
I have the Prestigio Multipad 4 QUANTUM 7.85 (PMP5785C) tablet
the device has 8gb memory but only 1gb for apps and games (1gb as internal storage and rest as internal sd)
There are ways to increase internal memory?
My device is root and i have init.d support
I've tried CronMod-INT2EXT+_signed but not work
Please help me!!

You may not be able to increase internal memory directly, but you can use your External SD card for installing apps and games, if your device supports External SD Card. There are couple of ways to do this.
1. Swap your Internal memory with External SD card
2. Use Link2SD to link to Ext partition in SD card to install apps and Games
Method 2 is superior, but more difficult to achieve. Method 1 is not recommended but less difficult to do.
Method 2 ->

This family of devices seem to mount partitions based on kernel parameters passed at boot.
It is possible to expand /data by using RK29xxImageTools to unpack the original image, modify the file containing the kernel parameters and repacking the image.
Attached you can find the parameter file I use with my Prestigio, I have doubled the /data partition to 2GB.
Keep in mind that:
/data will be wiped
/mnt/sdcard will be wiped
So you need to backup the tablet before attempting to replace the firmware.
What saddens me is that the ****ers @ Prestigio could not bother to invest the 10 minutes needed to do the same and release an updated firmware.

where is the modification in the file to change memory?
can i use all memory (8gb) as internal storage?
Thank you!!!

You need to change the size of the userdata partition and the offsets of the partitions that comes after it. It's not that complicated.
These are the values taken from the 2GB file I have provided (I have used 410000 instead of 400000 because otherwise the tablet would show the internal partition as being 1.9xGB instead of 2GB).
SIZE..............OFFSET
[email protected](misc)
[email protected](kernel)
[email protected](boot)
[email protected](recovery)
0x0002000[email protected](backup)
[email protected](cache)
0x00410000@0x00080000(userdata) <<<only change size
[email protected]0x00490000(kpanic) <<<only change offset
[email protected]0x00492000(system) <<<only change offset
[email protected]0x005B2000(user) <<<only change offset
You need to increase the size of userdata and recalculate the offsets for kpanic, system and user. You don't need to change their sizes. user does not have a size, as it will take whatever is left available.
I hope this helps understand how to do the calculations. The next offset is the sum of the previous partition size+offset:
Userdata size: 410000 @ offset 80000 <sum the values together to get kpanic offset 490000
kpanic size: 2000 @ offset 490000 (410000 + 80000) <sum the values together to get system offset 492000
system size 120000 @ offset 492000 (2000 + 490000) <sum the values together to get user offset 5B2000
user size nothing @ offset 5B2000 (120000 + 492000)
So if you want 3GB, the values would be (you may need to use 0x00610000 or 0x00620000 to have a round number):
0x00610000@0x00080000(userdata)
[email protected]0x00690000(kpanic)
[email protected]0x00692000(system)
[email protected]0x007B2000(user)
As a rule of thumb, every time you add 200000 to userdata, you are expanding it by (approximately) 1GB.
In my opinion you should keep some space (I would go with 512MB) for /mnt/sdcard (user) because there are applications (e.g. browsers) that can only save files in /mnt/sdcard .
This should be an interesting read as well.

Apart from the extra spaces you left in the params (e.g. "0x [email protected](kernel)" ), the numbers are hexadecimal, so the calculation need to be hexadecimal as well.
1GB = 0x00200000
6GB = 0x00200000 * 6 = 0x00C00000
It seems you did the math counting in base 10 (200000*6= 1200000).
If you google for the "SergioPoverony tools", it seems they include an utility to change the parameter file.

It seems you want too much and all at the same time.
With a 6GB data partition the SD card swap is pretty much useless.

Hi.
Any1 know i how can root this tablet?

@Boozezela, thanks so much for this ! :victory:
But for 3gb the value for userdata must be 0x00620000 !
So:

HI. tnx for all at the start. Is it possible that the external sd card is mapped as the internal sd card, and the entire memory give to the internal memory. I dont need 3 partition 2-4-32 or 3-3-32 i whant 6-32. All available memory to /data and map /externalsd to be /sdcard like on my phone.

Increase internal memory
Hello, I have a question regarding the second method of increasing the internal storage on a tablet
My tablet has:
- 1 GB internal storage;
- 14 GB INTERNAL SD CARD
- external SD card slot
My question is:
Is it possible to format and partition the INTERNAL SD Card partition of the tablet in 2 partitions and use one of them for linking apps with link2sd app ?
I've seen a lot of tutorials but all of them seems to refer to the external SD card, so I want to ask if it is possible to partition the internal SD card as well and use one partition for internal memory extension.
Thank you very much!
Best regards,
Alex

how do i REPARTITION Internal Memory ???

Hi all. I saw some great chances to repartition the Memory on some Android Tablets that use Internal Removeable microSD cards for their OS.
However, can it be done on a normal Tablet?
I Mean...
I'm getting a 7 inch Marvell10 (Marvel 800mhz) Android 2.2
256MB Ram and 2GB Internal Storage.
I WANT to resize the memory partitions so the APP section & Cache gets most of anything the system doesn't need.
IS THIS POSSIBLE? you can't remove the OS memory card in this.
If anyone knows how can you point me to a tutorial or pm the instructions?
I'd also need to know how to see what my sizes already are (and what space the system needs to remain).
MANY THANKS ! x7

Create partitions using Minitools partition wizard. Create ext4(256-512) and linux swap(0-128) partitions. Switch off your phone. Put the SD card in, trboot into recovery and wipe data. And then reboot.

Coul you just elaborate about the Linux swap file? Is it just like the virtual memory on the SD Card? Suppose if we have 16GB card and create larger EXT4 partitions, would we have to still create Linux swap partition of just 128MB?
For those who facing problem of low internel memory(ROOT REQUIRED)
No need to partition SD card
1) install the app
2) backup with titanium backup
2)uninstall the app
4) go to titaninium backup->Preferences->Restore Backup to->externel media
5) Restore the app with Titanium backup,,
by app2sd u can verify location where the app installed.
And your memory will never go low.. u can manage easily..

Through this way without partition, i guess the apps would be installed in FAT32 partition of the SD Card which is comparatively much slower to EXT4.

Recommended is 128 MB. 128 MB is more than enough. Swap basically is storage place which can be used as memory by the operating system when system RAM is low.
logi or prima

hi,
ok then use FAT32 is good enough for you...
-rkk
But think about the max. filesize with FAT32 (4 Gigabyte). If you don't want to use so large files, I would prefer FAT32 in all cases.
Good... But the question is : the ext4 working as fat32 as storage for files
Sent from my GT-N7100 using XDA Premium 4 mobile app
I think the best way is to try it, but I have read somewhere that ext should go, depending upon the android-version.
Accesing files via USB (in the phone) shouldn't be the Problem, but accesing via cardreader directly on windows did not (or rather not without special ext-drivers for windows).
Well, I think ext3 is the best option if you are going to have media files which are bigger that 4GBytes...
well... The other question is :what is the best for non-damage of microsd ?
I mean the card will minimize the ability to get a damage. What the file system type is best.?
Whith thanks
Sent from my GT-N7100 using XDA Premium 4 mobile app
hmmm, file system organization cannot damage your card, it is only a logic 1 or 0 on the electronics cells.
Maybe there is a difference between frequency of read/write operation. The more the bigger chance to damage a card... of course after a long, looooong time. I would recommend using ext3 as it's more scalable and stable than FAT32.
FAT32: File Allocation Table, 32-bit
Introduced: August 1996 (Windows 95 OSR2)
Directory contents: Table
File allocation: Linked list
Bad blocks: Cluster tagging
Maximum number of files: 268,435,437
Maximum file size: 4GB
Filenames: 8.3 or 255 characters, ASCII except for "'*/:<>?\|
Attributes: Read-only, hidden, system. volume label, subdir, archive
Ext3: Third extended file system
Introduced: November 2001 (Linux 2.4.15)
Directory contents: Table, tree
File allocation: Bitmap, table
Bad blocks: Table
Maximum number of files: number of bytes in volume/2^13.
Maximum file size: 16GB (1KB block) to 2TB (4KB block)
Filenames: 255 bytes long, all bytes except \0 and /.
Attributes: no access time logging, append-only, synchronous write, no-dump, h-tree, immutable, journal, secure-delete, top, allow-undelete.
Journal: metadata and file contents
There is no "best" filesystem, they are all optimized, to some extent, for different things.
Without lots more info, fat32 is relatively efficient and has far and away the best compatibility. For most users the compatibility makes it the winner.
Hi... I try the ntfs but.... But its incompatible with android.... So sad

NTFS is an windows-filesystem, and is only write- and readable on windows. Yes. linux can read it, but needs secial drivers for that and isn't realy fast. It is the worst filesystem for android or linux.
Use fat32 and ready!
Its fast, its compatible, and can be used in/ with most devices. The only disadvantage for you will be the filesize-maximum (4 GB).

O.K. I'll take your advice but I have a little question "how could I protect the micro sdcard from damage ? I suffered from a damge of micro sdcard several times.
Sent from my GT-N7100 using XDA Premium 4 mobile app
Until now I never had an damaged sd-card. And if it will happen, I have an backup of my important data. So I simply will buy a new one and play back this backup. Nothing is forever.
EDIT:
Ok, this 64 GB-SD-Cards are not realy cheap, but under normal conditions it won't faile for a long time, whatever filesystem you will use.

Android supports Ext4 so I'd rather use Ext4 than Ext3
you can format it by Fat32
sharing and expecting to learn
Hi all,
I am wondering about the partitioning of my new external memory card manufactured by Samsung Electronics.
The very same manufacturer initially develop F2FS, the Flash Friendly File System for the Linux Kernel.
F2FS was expected to be the fastest F.S. for solid-state disks, eMMCs, and SD cards.
Initial tests confirmed it. Nevertheless posterior tests reveal that ext4 beats F2FS (...).
My guessing is that not enough research/test have been done in the matter.
Im going to set the following layout in order to test the speed for each partition:
1._ 34,7G EXT4 -> pictures, movies, backups, etc... AND/OR moved: APPs by hard/sym links; DATA by folder mount
2._ 65,0G FAT32 -> pictures, movies, backups, etc...
3._ 19,5G F2FS -> moved APPs by hard/sym links; moved DATA by folder mount
Depending on the results (specific for my phone and configuration) included in the reports from Antutu, A1SDBenmarch (possibly others too), I will most likely either:
1._ format whole microSD as F2FS -> roms,apps,data,pics,movies,etc; access using the phone (adb, usb, wifi)
2._ format whole microSD as EXT4 -> roms,apps,data,pics,movies,etc; access using any type of linux and many others
3._ format 32G as F2FS -> apps; format 64G as EXT4 -> roms,data,backups,movies; format 32G as FAT32 (any file smaller than 4G I want to be directly accessed from any device through any card reader using any OS)*
* I won't use fat32 as ext4 read/writes speeds are bit faster and i dont need to access the sd using any device
My goal is to format the external microSD card as F2FS and internal storage. F2FS is not only supposed to be better in performance but also it is supposed to expand it's lifespam
Note: Regarding partitioning the microSD in the computer, only linux will allow resizing F2FS filesystems; windows software doesnt recognize it yet, therefore it treats the partition as unformatted, neveertheless it's possible to move it.
Note2: there are programs that allow the user to mount linux partitions and read/write data on them.
Phone: Samsung Galaxy Note 3 SM-N9005, rooted, resurrection remix 5.6 (current,next5.8)
Card: Samsung EVO Plus 128Gb microSDXC UHS-I Class 10 U3 Card
ROM: Resurrection Remix v5.6 (Marshmallow)**
S.Soft: Apps2SDpro: Linked -hardlinks/symlinks- apps to F2FS partition on ext.SD. App data (TuneIn Radio recordings) moved -foldermount- to F2FS partition on ext.SD.
** I am currently designing the multiROM layout which will probably include the current ROM, plus Resurrection Remix v5.8 (Nougat) kali and some others
cheers

Thread featured on XDA Portal
POSTED MAY 29, 2012 AT 4:00 AM BY POORCOLLEGEGUY
WARNING: This mod may degrade SD card life.
What you need:
MiniTool Partition Wizard for SD Card Partitioning
A MicroSD HC 4GB or higher class 6 or class 10
MicroSD HC Card Adapter
A card reader (if your pc doesn't have card reader built in | USB Mount is not adviseable)
Swapper2 from Google Play Store [DOWNLOAD]
ADB Shell or terminal Emulator (to check if swap is activated)
Make sure you have BusyBox installed
Before we start, lets do some reading . . .
RAM
What is RAM
Random Access Memory (RAM) is temporary data storage that the CPU uses during calculations. The more RAM a device has, the more calculated results the CPU can store - which means less time the CPU has to do the same thing over and over again. In other words, the CPU can check RAM to see if it has already made a particular calculation in the recent past. If it has, it can use the pre-computed results instead of wasting processing time recomputing the same calculation. In short, more RAM means a more efficient (and faster) device.
SWAP
What is SWAP
Swap is, in short, virtual RAM. With swap, a small portion of the hard drive is set aside and used like RAM. The computer will attempt to keep as much information as possible in RAM until the RAM is full. At that point, the computer will begin moving inactive blocks of memory (called pages) to the hard disk, freeing up RAM for active processes. If one of the pages on the hard disk needs to be accessed again, it will be moved back into RAM, and a different inactive page in RAM will be moved onto the hard disk ('swapped'). The trade off is disks and SD cards are considerably slower than physical RAM, so when something needs to be swapped, there is a noticeable performance hit.
Unlike traditional swap, Android's Memory Manager kills inactive processes to free up memory. Android signals to the process, then the process will usually write out a small bit of specific information about its state (for example, Google Maps may write out the map view coordinates; Browser might write the URL of the page being viewed) and then the process exits. When you next access that application, it is restarted: the application is loaded from storage, and retrieves the state information that it saved when it last closed. In some applications, this makes it seem as if the application never closed at all. This is not much different from traditional swap, except that Android apps are specially programed to write out very specific information, making Android's Memory Manager more efficient that swap.
Step by Step Guide
How to create Swap Partition
Using MiniTool Partition Wizard
Plug in you MicroSD HC Card to your computer using the card adapter. (Do not use USB Mount)
Open MiniTool Partition Wizard and look for the card
Right Click on it and select Delete Partition
Click on Apply to Delete the Partition
Right Click on it again and select Create Partition
Set the partitions as follows:
1st partition:
Label: Android-SD
Create as: Primary
File System: Fat32
Partition size: as much as you want!
2nd partition:
Label: Android-EXT3 (2nd partition is for EXT which you can use for A2SD or Link2SD)
Create as: Primary
File System: EXT3 (be it a custom kernel or ROM with EXT4 support, use EXT3 still -play safe! )
Partition size: MIN: 256 MB MAX: 1024MB (1GB)

How to use Swap
For us to be able to use swap file or swap partition, we need to use Swapper2 which you can get from Google Play.
Download and Install Swapper2 (of course)
After installing, open Swapper2 and navigate to Menu > Settings
Swapper preferences: (for kernels that doesn't have swap partition support)
Run swapper at startup (put a check)
Swap place: /sd card/swapfile.swp (you can place it in a folder if you don't like a messy sd card structure )
Swap size: MIN: 10 MB MAX: 256MB RECOMMENDED: 32MB (choose any)
Swapiness: RECOMMENDED: 10MB SYSTEM DEFAULT: 60MB MAX: 100MB (choose any)
Safe unmount (put a check)
Safe remount (put a check)
Advanced preferences: (for Kernels that supports swap partition only)
Use swap partition (put a check)
Swap partition: /dev/block/mmcblk1p2
After setting preferences, press back and tap on "ON" to turn on swap. Reboot afterwards
How can I tell if swap is running?
Go to the terminal emulator - or open adb shell - and run 'free'.
If it looks like this (with zeros in the swap line), you do not have swap:
If it looks like this (with anything other than zeros in the swap line), you do have swap:
NOTE:
You need to turn off swap before you mount SD via USB, if you don't you will not be able to mount sd as swapfile is active and set to read only which will deny request to mount USB Storage.

Increase RAM using Swap File and Swap Partition
NOTE:
I spent hours updating my guides and I don't ask you to press that THANKS button, be kind enough not to copy my guides to other forums. I know some noobs want to make a name on other forum boards... but hey, that's not an excuse!

WARNING: This mod may degrade SD card life.
What you need:
MiniTool Partition Wizard for SD Card Partitioning
A MicroSD HC 4GB or higher class 6 or class 10
MicroSD HC Card Adapter
A card reader (if your pc doesn't have card reader built in | USB Mount is not adviseable)
Swapper2 from Google Play Store [DOWNLOAD]
ADB Shell or terminal Emulator (to check if swap is activated)
Make sure you have BusyBox installed
Before we start, lets do some reading . . .
RAM
What is RAM
Random Access Memory (RAM) is temporary data storage that the CPU uses during calculations. The more RAM a device has, the more calculated results the CPU can store - which means less time the CPU has to do the same thing over and over again. In other words, the CPU can check RAM to see if it has already made a particular calculation in the recent past. If it has, it can use the pre-computed results instead of wasting processing time recomputing the same calculation. In short, more RAM means a more efficient (and faster) device.
SWAP
What is SWAP
Swap is, in short, virtual RAM. With swap, a small portion of the hard drive is set aside and used like RAM. The computer will attempt to keep as much information as possible in RAM until the RAM is full. At that point, the computer will begin moving inactive blocks of memory (called pages) to the hard disk, freeing up RAM for active processes. If one of the pages on the hard disk needs to be accessed again, it will be moved back into RAM, and a different inactive page in RAM will be moved onto the hard disk ('swapped'). The trade off is disks and SD cards are considerably slower than physical RAM, so when something needs to be swapped, there is a noticeable performance hit.
Unlike traditional swap, Android's Memory Manager kills inactive processes to free up memory. Android signals to the process, then the process will usually write out a small bit of specific information about its state (for example, Google Maps may write out the map view coordinates; Browser might write the URL of the page being viewed) and then the process exits. When you next access that application, it is restarted: the application is loaded from storage, and retrieves the state information that it saved when it last closed. In some applications, this makes it seem as if the application never closed at all. This is not much different from traditional swap, except that Android apps are specially programed to write out very specific information, making Android's Memory Manager more efficient that swap.
Step by Step Guide
How to create Swap Partition
Using MiniTool Partition Wizard
Plug in you MicroSD HC Card to your computer using the card adapter. (Do not use USB Mount)
Open MiniTool Partition Wizard and look for the card
Right Click on it and select Delete Partition
Click on Apply to Delete the Partition
Right Click on it again and select Create Partition
Set the partitions as follows:
1st partition:
Label: Android-SD
Create as: Primary
File System: Fat32
Partition size: as much as you want!
2nd partition:
Label: Android-EXT3 (2nd partition is for EXT which you can use for A2SD or Link2SD)
Create as: Primary
File System: EXT3 (be it a custom kernel or ROM with EXT4 support, use EXT3 still -play safe! )
Partition size: MIN: 256 MB MAX: 1024MB (1GB)
3rd partition:
Label: (do not put anything)
Create as: Primary
File System: Linux Swap
Partition size: MIN: 32MB MAX: 1024MB(1GB) RECOMMENDED: 256MB
