Partition the internal memory for better App management - Galaxy Tab S Android Development

Wanted to ask if someone knows a way to expand the internal memory?
For the S2 there is a possibility that works well but I haven't found anything for the T805.

i have re-partitioned my device long time ago, but i cant remember which device it was. i just changed the pit file manually to increase one partition size by reducing another nearby partition size. it was not difficult but could be hazadous, even you have the original, pit file

Mod for Encreasing The internal memory??

Excuse me, is there any mod for increasing your internal memory like galaxy s3 having your micro sd like internal memor??
Thanks!!

nope, that requires repartitioning so that the sizes are split differently in the internal memory...i don't think anyone cares about this as long as the phone supports 64GB external.... the method was used for reviving the superbricked phone a year ago on ICS smaller system partitions resulted in a successful booting rom but with less storage.
But is there any way for installing all app and games in micro sd like kernel perseus whick allow install all in microsd whatever app or game
Thanks!!!

I've had luck with the FolderMount, liked it and bought the full version. There's a thread for it in the themes and apps section
PS. You should open new threads in the right sections :good:
There was a mod on the S3 that swapped the internal and SD memory - i.e. it fooled the system in thinking the SD card was internal.
Give it time, im sure the mod will become available - you will probably need to root

AFAIK the trick was modifing the vold.fstab file in system/etc/ still i think its useless since the most space is set on internal sd and not the system swapping them makes your storage space even less than it already is...who wants that to happen ?
he can get a light ROM i've seen one in the forums calles biochemical TW i think not quite sure which is 800MB well stripped but still he can add what he needs only and not get to the crazy 1.5 GB system

[Q] Internal Storage Size 19505

Hello
I've recently flashed [Rom]Google Edition galaxy S4 rom for i9505 [27 June] [Pure Nexus Experience] onto my S4. After following all the instructions it's working fine. Except the internal storage size is still 9.25GB with 8.18GB allocated. I would have thought that removing the stock ROM would have freed the internal storage space?
Cheers.

I think you answered your own question, "allocated" means "reserved" so in other words even if you
did not have any rom flashed/installed at all the phone would still allocate/reserve the 8.18GB space
which cannot be used for normal storage.
Good luck!
Thanks for your reply. It's a bit of a bummer though, is there no way to release the total storage size of the phones internal memory for user allocation ? Would it be something the developers could work on. But then I guess it comes back to the old saying, just get an SD Card.

I doubt that any of the devs could increase the user usable space on the internal sdcard.
But even if they increased it by 1GB or 2GB no one including you would be satisfied with
that for more than a few minutes anyway.
The external sdcards are really not that expensive and spending $20-30 bucks on
32GB sdcard for a device which cost over $650 is not that big of a deal.
I would think the actual GS4GE has a different pit file.
actually i thought it would free up internal storage after flashing cm10.1...
I already flashed and indeed its still the same space as TW.. puzzling..

People have answered this many times. The size of storage you get will not increase unless Samsung changes the partition size.
repartition
isn't possible to re-partition. I am sure samsung had a good reason to book 6 GB for OS. but stock edition will not need all this space! i would say maybe not more than 3.
so cant we repartition the reserved to achieve usuable of 13GB?

Yes you can but its very risky. See below
Skipjacks said:
In order to partition that internal memory you have to wipe it. And that means everything. System, recovery, download mode, boot loader, everything.
The connection with Odin or adb at this point would be totally housed in RAM. It would need to maintain that connection in order to complete the task of adding the new partition, adding the download mode back, adding recovery, and finally the ROM itself.
If the phone lost its connection during that process or lost power or the update process got pushed out of ram for any reason the phone would be hard bricked as there would be no way to reestablish communication with it to restart the process. You couldn't power it on or boot it to anything. It would be a $600 paper weight.
Meanwhile the alternative option is to just go buy an $8 external 16gb SD card or a $20 external 32gb SD card. That carries no risk whatsoever and expands your phone's storage well beyond the original 9gb of usable space you started with.

thanks for the info. but i dont see why i would lost power during the process or anything like that. is it the same risk as flashing a rom via odin?
Is this why I am only able to use about three gigs of my internal storage space? I see 3 or so are partitioned off for the ROM (See second attachment from within TiB), then I have 10 gigs, but 7 are full of something I can't locate - either from within my phone or through my computer (See first attachment from within ES File Explorer).
I've got to assume this is just something going on with my phone. I think everyone would be pretty upset if their 16 gig phone only gave them 3 gigs...
I wish we had something like DTa2SD for the S4! That would be great...

When everything goes well you are right, you will probably reflash the partition 1000 times without having any issues... the problem is if you were to be unlucky
No the risk is not the same as flashing a rom. If the process of flashing a rom is interrupted you just wouldn't be able to reboot your phone normally but you could always reboot in recovery or download mode to retry flashing the rom.

No you should have 8/9 Gb free on your Internal SD. The space you lose are the 2.19Gb in the system partition, but you have definitely something that is occupying your Internal SD.
Well crap. Any idea how to get rid of whatever it is? I can't get my phone to go into mass transfer mode at all (even with the SG USB Mass Transfer app) so the only thing I can do is browse on my phone through file explorers and nothing can see it.

[Q] How to recover photos from memory stick?

I accustomed to storing their audio or video file like photos into a mini memory stick. However, how can we recover them once lost? What can I do ? Any software like Power Data Recovery?? 3Q for your advice.
Wait, what does this have to do with Win8? I'm confused (or maybe you are)...
Assuming "memory stick" (whatever the <REDACTED> that is) exposes itself as a standard block-storage device, you can probably use whatever recovery tools you're used to... no guarantee they'll work, though.
I've had a positive experience using MiniTool Power Data Recovery.
It worked wonders on a flash disk that apparently lost its data, but with this software I could recover most of them, although with very ugly file names.
There are 4 options which can be confusing but I've mostly used Digital Media Recovery and Undelete Recovery.
For non media files, the result wasn't so great but I recovered some files from an almost defective SD card.

yup, any recovery software will do, just defrag first before recovering for best result

Worst result dont you mean... Recovery software relies on the fact that when deleting a file it is simply removed from the file table but the data itself is still present. Defragging will move files around and will now believe where your file previously existed is now unallocated space and will happily over-write it. For recovery software to work at its best you need to ensure as few changes are made to the file system as physically possible.
SixSixSevenSeven is correct. Leaving aside the fact that defragging a flash storage device (like a memory stick, SD card, SSD, CompactFlash, etc.) is a terrible idea in general*, it will drastically reduce your chances of being able to recover any data at all. If you have already done a defrag, the odds are very good that your data is now unrecoverable.
* Win7 and up know not to actually defrag Flash-based storage, but what they do instead - called TRIM, and intended to optimize the storage - is almost as bad for purposes of data recovery. TRIM tells the "disk" that the physical memory cells which were storing the data of deleted files are no longer needed, which typically has the effect of zeroing the data.

64GB Kernel Script Patch for Z1

Hey Guys,
I asked @kokotas to help me figure out a way to make a Patch to extend the Internal Memory as for me, due to the size of the high-end Applications and Games, is too limited 16GB, 11,70GB available only, on our Z1.
So my first Idea was to sacrifice 16Gb Internal Memory and use 64GB External SD Memory formatted in EXT4 where all the Data will be stored.
To do so we have to understand few thing and how is the structure of the Z1 Kernel is made and try to extract "ramdisk.cpio" where we can edit "init.rc" and change the line "/data mount"
As for the kernel "Autopsy" we used @krabappel2548 kernel build, I hope he is fine with that.
From what we know, the recovery is injected in the boot.img and this makes things more complicated.
Are all kernels built in this way? Even the stock ones?
Also, is there a specific rule in the way of naming the included ramdisks?
I attached a picture to make things more clear.
Any help will be appreciate.

1. Sony doesn't have a recovery partition in their phones hence developers add the recovery in the ramdisk. Also stock sony kernels doesn't have a recovery included by default only bootloader/flashmode.
2. You can't adjust the 16gb internal partition without diving deeply into the bootloader. The NAND partition profiles are hardcoded in the bootloader so modifying even just a little bit of info in the partition of the NAND would brick your device. The only way I could possibly suggest to try is hijacking the fstab and ramdisk to unmount the internal storage and mount the external storage on init. But if your issue is only about disk space I suggest you leave the internal storage and just symlink the obb folder instead of hijacking the whole internal storage. And BTW the disk IO of the internal storage is worlds apart compared to your microsd card no matter what class it is so it would be very unefficient if you use your microSD card as internal. IMHO reading the dalvik-cache 1 by 1 on startup would be pretty slow! Same goes for reading the byte code of an app once you open it.

We know that. If there will be a Partition for recovery it will be much more easy and safe. That why we also used a Kernel with recovery implemented.

I know the difference between Internal and External Storage. Yes the internal bandwidth is higher but like I said is worth the sacrifice, or try. Best solution will be System and Apk on Internal and link the SD to use there all Data. This is more efficient that a third Apps like Link2sd or kind of. BTW, I don't think it will be so slow but we have to try. The idea have to be made to improve what next.
So we need more Ideas, do you have any?

A: This isn't about risk this is a fact. Once you successfully manage to alter the partition table of the built in NAND you're sure to get a hard brick from doing this.
Maybe not the whole internal storage but implement the external SD with the internal?
A: Implementing internal storage with external to support it is possible but limited. Like I said you could symlink the obb and Android folder to the external storage. That way you can allocate some of the storage space to data, dalvik etc. and the data files to the external SD which uses the most resources.

We do not try to repartitioning the Sony Z1 internal memory to get a recovery bootable from different partition, which still a very good idea to develop for Z1. We try to mount the External SD instead of the Internal to expand the storage for the Z1, and here we need a patch. If kind of patch like that will really work, with some help, anyone just will format the SD in EXT4 and use what like he like, 32/64GB.
So we will be glad even to involve more "Programmers" to help us make it true.
So any way to let this work?

Expand storage. You will be able to format a 64GB, micro SD in 2 Partitions and use 32GB by the System and 32GB like a normal SD, for example, and it will be managed by the system and not by Apps. So instead of 11,70GB you will have 30GB in System.
Surely this will just make accessing the SD card data really slow? Even with a class 10 running games off the SD card would be laggy as hell

Yes it is possible but not easy... I'm pretty sure the dev that made that had a hard time before he successfully got it. Also I'm pretty sure he has a JTAG box so in case his phone got hard bricked he can easily fix it again. Also IMHO that was already patched by sony on the latest s1boot so I'm sure it's alot harder than before.

Only problem with having the SD used all the time for system files is the risk of corruption and or a failed card.
Saying that I had it on the S3 and it worked brilliantly, was a relatively simple script which required init'd support from a custom kernel.
In all fairness, after using folder mount the worries i've had with my internal memory have gone, i'm always over 10GB of space with several really big games installed which would easily take over the whole internal memory.

I had it on HD2 as well and never had any issues and I had full control of my device, this is what also we looking at, no restrictions and no storage limit on a high-end device. I will be glad to see 64GB recognized as my System Storage instead using Apps on Apps like the Mount Folder.
I play Most Wanted, of curse a bit slow, on mine HD2 so if we get this work we will have 40mb/s in writing and reading, instead of 70mb/s in internal, due to the limitation of the slot. I think even with a kind of transfare like that you will never see any slow down of the performance on your device.
Some Smart One will say now to me "Why then you don't go back to HTC". That's the point! Imagine have Z1 with such a Development and full control of you device.
At last it's a choice of the user if he want apply that patch or not, but I think if this will be possible many will be happy, but like I can see, we don't have much support due to the risk and any Developer will not take this in consideration, or maybe will, but apparently not now.

So I was thinking about 64GB HTC One, or wait for the next release and I will finally be fine. For the moment I try to deal with Z1, I hope somewhere we will have 64GB system storage , this maybe will change my mind, everything is possible.

[6039] Hidden/unused internal memory

During the research in order to build the TWRP recovery for this device I have noticed a very interesting fact. Although the phone is sold as a device with 8 GB internal memory, the memory chip used inside seems to be two times bigger. There is an unused (non-formatted) partition "mmcblk0p38" labeled as userdatabak and its size is 7816 MB. There is no data there, it is a completely blank partition. It will be interesting if the mmcblk0p37 (userdata) partition can be resized in order the reported internal memory of the device to be increased. I intend to experiment with this soon and will post an update here if I have some success. If anyone is interested and is willing to share ideas regarding the resizing I will be glad to see them.
does parted print show the partitions?
The 6039k (dual sim version) already has 16gb of rom and 1,5 of ram, maybe the parts used in the mono sim one are the same but just turned down, still strange for the manufacturer to cripple the phone on porpuse, more memory means an even better phone for the price and more sales...

No it doesn't. The partition table contains a protective MBR sector, and unfortunately parted cannot handle this layout. I'm playing with a raw image of the entire phone memory and successfully resized the partitions in it. But I used gdisk and resize2fs ... gdisk however is not available in the recovery mode on the phone. In this thread @meghd00t has a static build of gdisk which should do the trick. I will try to use it later directly on the device.
SUCCESS!!!
I did it ! The static build of gdisk works perfectly (big thanks @meghd00t). Here are screenshots before the repartitioning and afterwards. I will post a guide how can be done later today.

I also considered the possibility they sold it as an 8gb because areas in the 2nd partition did not pass quality standards and could possibly result in data loss over time. Cpu makers used to sell quad cores that failed tests as dual cores with the other two cores "locked"....and of course folks figured out how to unlock them but the system would crash from time to time.
Maybe the 6045i has 32GB??? Jajaja

Initially I thought about this too. It is possible. But how can we know this? And why you will leave a completely blank partition there ? Belive me there is nothing else than zeroes in it.

Not likely. The memory chip probably will not leave the factory with size bigger than the offered from the actual manufacturer of the device (the phone in this case). If there are bad blocks they will not be seen by the software and will not be available to the user at all. But this is only a speculation based on my limited knowledge on the NAND chips (and little googling about the NAND technology). For now my device works with internal memory twice bigger than the initial one and only the time will show how durable the memory chip is.
And hey this is xda-developers. Why we participate here if not to play with our devices ?

Sorry...no userdatabak partition on the 6045.
Thanks for sharing that. Im very interested in expanding my storage but how would that work with any further update such as OTA or even rooting? Would we have to undo the partition, would the update force us to re partition afterwards, or does this thing have no influence whatsoever to all of this? Sorry if the question seems stupid

Rooting has no relation to the expansion of the device internal memory. Regarding the OTA ... who knows. Do you have an official update? I do not. In the upgrade for the 6045 the checks were only for the system files and the recovery partition. But prior an official update we can't know how the same will work. Personally I don't think that the owner of a modified device should use the OTA prior to check what will happen after it.

Okay. But then is there any way to undo these changes in order to get OTA updates? Would restoring from a system image or any other form of backup affect the partition and get it back to its original state? Or should we definitely not try to expand the memory if we want updates?

The resizing of the partition does not require root access (except from the recovery during the resizing), so you will be able to check for OTA updates (from the phone) and to receive them (when such are available), if your device is not rooted. As I said earlier however, because we still don't have an official update, we don't know what will be the checks in it and also what modifications will be included.

No, the size of the partition will remain the same. To restore its initial size you will have to use gdisk again (in order to change the GPT layout), or if you have a backup of the entire memory chip (mmcblk0) prior the repartitioning, to flash it back to the device.
Thank you for this great find. I can confirm partition #38 (7.3Gb) exists on my 6039Y -2AVDRO7. Still, I'll wait for feedback if future OTAs work ok with the extended partition space.
@petrov.0 did you try to write and read from the extended memory blocks after the new allocation? I mean, is there any chance that the partition was only simulated and data might get corrupted?
@ anyone can post the partition table from a 16Gb DualSIM 6039Y, out of curiosity? thanks

Yes I did. I filled all the space with raw partiton images and then checked their md5susms.
