Hello,
Some "stupid" question, but i dont find here.
Is our device S-On protected? My old phone was,and when i tried modify files in /, like fstab, it restored to default every (Re)boot.
I want modify fstab and use my SD Card (64GB Class 10, Uhs-i not supported) as internal storage..
And what fstab file i have to modify? Here is 3 fstab files.

I have a generic Allwinner A13 7" tablet essentially identical to this one. The internal memory is set so that part of it is seen as internal, and part as a fake SD card mounted on /mnt/sdcard. Actual SD cards get mounted to /mnt/extsd.
I find this very annoying for a number of reasons, and would like all the internal memory to be seen as internal with no fake SD cards, and SD cards to be mounted to /mnt/sdcard. If this were one of those tablets capable of running Linux I'd run gparted and do the job from there, but it isn't.
Is there any way to merge the two internal memory partitions into just one?
I'm aware I can edit vold.fstab and invert the two mount points, and I'll keep it as a fallback solution, but I hate the idea of wasting a gig of useful internal space like that.

Of course your tablet is capable of running Linux, it's an Android. All Androids are running Linux. I guess you are referring to GNU/Linux. You can extend any Android device with GNU/Linux as well, but this is another topic.
You want to merge the internal space today allocated for /data and /mnt/sdcard? If your device memory is of type MMC, you can do this by using qparted or similar partition utility. Depending on what utility you are using, and the layout of the partitions, you may have to redo the entire partitioning, saving and restoring the contents of the partitions.
If your device is using a MTD memory type, there's no partition table, but they are hardcoded. This way, you most likely have to reverse engineer your boot loader, changing the partitions sizes. This is much more complicated.
Another easier way, is to simply ignore the usually quite small internal storage used for /data and create a new partitions on the SDcard, and mount this as the new /data partition. This way you can allocate as large /data partition you like (at the cost of less SDcard space). The drawback is that you always must have the SDcard inserted for the device to work.
you can insert to you tablet sdcard with preinstalled debian. And after that you can do everything. I tryed dd of=/dev/nand and cleaned all nand.
Plan A:
1) You can find some prepared rootfs image (i cannot post links), unpack and dd this image to 2Gb sdcard.
2) mount -t vfat -o rw /dev/sdX1 /to_somewhere/, and copy to first partition you're precompiled kernel and initrd (optionally), script.bin from tablet's /dev/block/nanda.
3) Shutdown your tablet
4) insert sdcard with debian into tablet, also you need usb keyboard
5) power on. login: root; password: password. And do what ever you want! (in command line)
Plan B (my favorite):
1) Unsolder Nand memory chip (you need some solder, heatgun)
2) Solder Chip to some USB Flash drive.
3) Insert USB Drive to the computer.
4) Unsolder nand from USB Flash and solder it back to tablet !
Hi there,
does Android allow to divide an external sd card into several partitions?
I´d like to get a bigger sd card and create at least 2 partitions on it. One unencrypted for easy access and one encrypted with dm-crypt to have a secure storage.
Is this possible? Would this then give me /storage/sdcard1 and /storage/sdcard2 and so on?
Can you manually change /etc/fstab on Android?
Hi guys,
I want my Venue 7 support NTFS or EXT4 file system so I could download game matches (videos) larger than 4GB.
I found apps like Paragon NTFS/HFS+ but it doesn't work on my tablet even if I have it rooted and granted this app superuser assess. When a 32GB NTFS SD card is inserted, this app simply tell me no NTFS/HFS+ partition found and the OS warned me that a blank SD card is detected or unsupported file system detected and want me to perform format/erase. After formatting the SD card was with FAT32 file system and that's not I want. Sarcastically this app works on my low end Samsung phone and that phone could read 32GB SD card with NTFS format with the help of this app. So as the same for EXT4 file system
So my problem is: could anyone get a SD card with NTFS/EXT4 file system works on this tablet. I wanna download World Cup matches cuz I work while the game is going on Thanks for anyone's help.

I have checked and I have bad news for you:
1. The tablet has built-in support in kernel for following filesystems:
Code:
ext2
ext3
ext4
vfat
msdos
fuseblk
So and NFTS, exFAT are out of question, unless we add the support through fuse (ntfs-3g?) or as a module (it would require current kernel source which I am not sure we have).
Also, when I format the first partition of an SD-card to EXT3/4 which it supports, the card is not be mounted, even with permissions for anybody to write set.
You could of course create a second partition, use some tool like to mount it automatically and another to map the directory to an actual directory on SD-card, but that would still require root and would be complicated.
In short, the answer is no, it is not possible right now.
Hello,
my Xperia ray does not mount (working) 16GB SDHC card that I formerly repartitioned to provide additional space for applications. Following this tutorial
xperiablog.net/2011/12/12/link2sd-guide-never-worry-about-internal-memory-limits-again/
I've set up 2 partitions, but phone recognized none of them. Neither did Windows, when card was connected through Xperia. Using card reader, I've managed to delete both partitions with partition program and make one FAT32 again. After formatting, this SD card is working properly in Windows, but doesn't in Xperia ray (and another Android phone). Another card is mounted in my phone flawlessly.
CWM Recovery also can't mount this card. I've even changed from CarbonROM to one that I believe to be stock (ST18i_4.1.B.0.587_CE_1252-3693_ForsakenNGL.ftf), but it didn't help. I dont know whether is it related, but none of kernels (ROMs?) i've tried had partition table file in flashtool menu. Does any of those have one?
How to repair this memory card?
EDIT: Problem solved, all that was needed to do was to change state of partition from "Logical" to "Primary" in partition program.
Hi guys,
I'm trying to backup files to my SD Card from an app located in the data/data folder.
I'm using ES File Explorer to copy the files, however after viewing the properties of the copied files I've noticed the following.
Owner: 00000 - root*
Group: 01028 - sdcard_r
Whereas the original file displayed owner & group as the app accessing the file.
Any help on creating copies of files with the original permissions/owner/group maintained would be much appreciated.
Phone:*
Rooted Samsung Galaxy Ace Plus GT-S7500*
16 GB SD Card Fat32 (windows formatted)*
Cyanogenmod 11*
Android 4.4 KitKat
Would this have anything to do with the filesystem used?
As the SD Card is Fuse/Fat32 whereas internal is ext4.
At this point i've decided to store the backed up files as zips, which is retaining file permissions when extracted directly to internal memory. But not so when extracted to the SD Card.
Fuse mounts, fat32 and ntfs don't support ext style permissions.
Normally I tar the files to help retain that info.

Thanks, so i would have to convert the external SD Card to ext4 to retain permissions for uncompressed copies then.
I would not recommend that as you would have to modify your boot images fstab and then windows would never be able to mount it. Instead you could shrink your sdcard partition then add a new ext one, after that you could either use a mount script or app to mount it. Also if you want to preserve permissions add the -p flag to cp
