First things I did before and just after rooting - Galaxy S III Mini General

Hey all.
Tools I used for flashing and backup:
on PC linux box:
- heimdall - which does the flashing
- netcat - (nc, ncat or netcat) tool for writing to or reading from network.
- partx - assigns partitioned disk images as kernel's loop devices like: loop0p2...loop0p25
on s3 mini:
- busybox
- "Rooted SSH/SFTP Daemon"
Before rooting reboot the phone to the download mode and download
the pit file with:
Code:
heimdall download-pit --output goldenxx.pit --no--reboot
Root your phone and install busybox and ssh daemon on it.
Start sshd but close all other apps to keep filesystem activity so low as possible.
start netcat on your PC:
Code:
netcat -l 192.168.0.11 5050 > mmcblk0.gz
Now netcat is listening for input from your lan (Replace address to corresponding your PC's IP address)
Now try to connect to your phone with ssh. When you got an # prompt then:
Code:
sync
and send your whole internal storage from phone to your PC:
Code:
cat /dev/block/mmcblk0 | gzip | nc 192.168.0.11 5050
Do not start any apps on your phone before you got back the command prompts both on phone and PC.
when you got a command prompt again and no error messages was printed. you should have an
gzip compressed disk image of you phones mmc on your PC.
Check its integrity running
Code:
gzip -t mmcblk0.gz
If the package is ok, copy the goldenxx.pit and mmcblk0.gz to the sure location.
Now you can make an uncompressed copy of mmcblk0.gz for example:
Code:
zcat Backup/mmcblk0.gz > ~/mmcblk0
With partx you can use the image like any other partitioned disks running as root:
Code:
partx -v -a ~/mmcblk0
it should print something like this:
Code:
partition: none, disk: mmcblk0, lower: 0, upper: 0
Trying to use '/dev/loop0' for the loop device
/dev/loop0: partition table type 'gpt' detected
/dev/loop0: partition #2 added
/dev/loop0: partition #3 added
/dev/loop0: partition #4 added
...
/dev/loop0: partition #25 added
and print out the data of partitions associated within kernel:
Code:
partx -s ~/mmcblk0
Code:

now you can explore the partitions and make images of it. For example:
Code:
file -s /dev/loop0p11
/dev/loop0p11: Linux rev 1.0 ext4 filesystem data, UUID=1b70457a-e011-c65a-87c6-f346bd874821, volume name "efs" (extents) (large files)
Code:
cat /dev/loop0p11 > ~/efs.ext4
and...
Code:
file -s /dev/loop0p16
Code:
/dev/loop0p16: data
It is modem.bin so:
Code:
cat /dev/loop0p16 > ~/modem.bin
Note that ext4 images must be transformed to the right .img-file form with ext2simg tool before flashing.
Be careful before flash your phone with these files.
remember to unmount all /dev/loop0 -partitions and finally
Code:
partx -d /dev/loop0
losetup -d /dev/loop0
because the images was copied from running system,
all writeable filesystems are not clean. So you might want to e2fsck these partitions.

take a NSTG back to stock

Hi,
I succesfullly rooted my Nook glowlight, but when I tried to go back to stock with my nook backup I found the backup was not ok (just 77MB) and now I have a bricked NSTG that won't get past the "Install Failed" screen.
I've tried almost every method I could find in the forums, but none worked for me.
Is there anything else beside n2T and Alpha-Format I could try to revive my device?
TIA
I think the most careful way to proceed here is to get a shell going and inspect the damage.
If you were lucky you just wiped out the first partition and the partition tables.
Reinstating the partition tables might make undamaged partitions visible.
It's important to preserve the device dependent info on the /rom partition.
If you copy over ClockworkRecovery onto an SD card you should be able to boot that.
Without selecting anything on the menus you should be able to get ADB working.
With an ADB shell you can run fdisk -l /dev/block/mmcblk0
As soon as you can get access to /rom I'd suggest that you back that up.
I'm sure somebody has other ways to get shell access.

thanks for that I'll give it a try...
Sadly, I'm on a W7 box (not mine) and all I can see in the device manager is a nook with a yellow sign in it
ADB devices returns a blank list....
I tried updating the drivers for the nook: first uninstalled anything nooklike with usbdeview, and then pointed W7 to a folder where I had downloaded usbdrivers from this thread http://forum.xda-developers.com/showthread.php?t=1354487 but W7 keeps telling there are no drivers for nook in that folder.
If I boot without SD then the nook is recognized and USB drivers install fine. It's booting with CWM that the device is not recognized.
Stuck
There are drivers and drivers.
As a composite USB device the Nook uses both the stock Windows Mass Storage driver and the Google ADB driver.

The best bet would be to check with somebody with a Glow to see if the partitioning is the same as the Touch.
They could have even changed the exact size of partitions over time for the same model.

mmmm, a bit risky isn't it ?
I think I'll read the rest of the internets before proceeding I need to understand this.....
thanks again

Well, you don't have anything at all in your partition table, not even the correct CHS.
If you tried this configuration and you can't mount the partition, then no harm is done.
It will only mount if the partition formatting makes sense.

booted in gparted live and took a peek at the Nook. This is what I found (sorry I don't know yet how to post images):
Device information
Model: B&N Ebook Disk
Size: 182 GiB
Path: /dev/sdb
Partition table: msdos
Heads: 255
Sectors/track: 63
Cylinders: 238
Total sectors: 3825664
Sector size: 512
Physical characteristics being so different I'm affraid trying to convert heads/cylinders from Renate's Touch to my Glo schema would be useless.
Could someone with a NSTG please share partition information?
Thank you all,

Well, they are not real physical differences.
You can juggle heads and sectors/track as long as the size of a cylinder stays the same.
It may be that the Glow has gone to a bigger cylinder, but it's suspicious that it's not a power of two.

Here is a script that will partition your Nook internal SD card like the listing above.
You can either copy this to the SD card, chmod 777 it and run it
or just copy and paste it to the Windows command line window running ADB.
Then you can try some mounts and see what you've got.
(nookpart.sh is zipped.)
was about to try the script (thanks again!) but nook is stuck at "rooted forever" screen and nothing I do awakes it: power on, power on 30 sec, power on and n, plug it to pc, and every combination. Took off the sd and tried combinations again, nothing. I've searched a bit and all other cases resumed to reboot by pressing long power. Not this one....no hard reset available? Every piece of equipment must have a big red switch =)
Should I stop messing around and buy another one? (not in the states anymore, it will take like 40+ days to deliver here...)
EDIT: false alarm, battery was too low to power on. Where did the full charge go? I dunno....30 more minutes before I can try

From CWM tried to mount /boot and failed. Took off the SD, booted nook (fingers crossed) and it displayed the "install failed" screen.
Nice try, thanks for the patience :good:
No, that's what I expected.
The partitioning worked fine
You had already bashed the boot partition.
Now try:
Code:
mkdir /rom
mount -t vfat /dev/block/mmcblk0p2 /rom
ls -l /rom
Looks like there was already a /rom
Code:

in the meantime I booted noogie and did a backup of the semibricked nook just in case.... =)
Now I'll write CWM to the SD and boot again
That means that the partitioning is correct and that your /rom is intact.
Make a good backup of your personalized stuff:
Code:
adb pull /stuff
Now you have to fix up the boot partition.
I'd probably try to install the factory.zip
Code:
mkdir /fact
mount -t ext2 /dev/block/mmcblk0p3 /fact
ls -l /fact
Code:
adb pull /fact/factory.zip
adb pull /fact/rombackup.zip
Then copy factory.zip to the external SD card and do a CWR update with that.

Ok I managed to mount it.
You most probably have an unpartitioned sdcard, clockworkmod however assumes that is partitioned and wants to mount the first partition (/dev/block/mmcblk0p1).
You can fix this by repartitioning your sdcard so that it has a mountable fat-formatted first volume and then retry.
If you don't mind using the commandline, boot to recovery and connect via adb shell to it, then mount your sdcard manually: mount /dev/block/mmcblk0 /sdcard and retry.
Technical explanation:
cat /proc/partitions lists:
/dev/block/mmcblk0 is your FAT formatted volume (no more partitions at all)
should be:
/dev/block/mmcblk0 (whole device)
/dev/block/mmcblk0p1 (1st partition, FAT formatted)
/dev/block/mmcblk0p2 (sd-ext partition, only for those that use SD2ext and such)

Source: http://android.stackexchange.com/questions/24427/cant-mount-sdcard-from-recovery-mode-clockworkmod
By running the command
Code:
mount /dev/block/mmcblk0 /sdcard
I can now access the sdcard, but this is only a temporary solution. How do I make it so that I don't have to manually mount the sdcard?

[SCRIPT] Fix partition table for Android 4.4

Since the gapps for 4.4 need very much space wee need bigger system partitions.
I've created a script which automates this process and increases them both to 840MB.
the space is taken from the userdata partition.
You should backup your whole phone before doing this(storage will not be touched but you shouldn't take the risk)
I tested it with 32GB version only so if you want to know if it will work for 16gb, too give me the output of this command:
parted -s /dev/block/mmcblk0 print
Download:
http://d-h.st/FWz
Instructions:
1) boot into CWM
2) adb push repartition.sh /tmp
3) adb shell chmod 0777 /tmp/repartition.sh
4) adb shell /tmp/repartition.sh
5) adb reboot recovery
6) now you can do all the usual stuff like enabling TDB and installing ROM's
Sounds great but I cannot test it, since I dont have any parted binaries (at least in my 4.1.1 Wajk Wiui ROM) ? Can you please tell me where I can get them.
Second Question:
Im currently running TDB:
System 1 latest WIUI 4.1.1 v5 ROM
System 2 MIUI v6 1.9.19
Both system partitions are completely full (usage 98 %) and the same with the data partitions ( usage 97 % )!
Would it be possible to decrease /sdcard space and repartition it like the following with TDB enabled:
system 800 mb
system1 800 mb
data 1500 mb
data1 1500 mb
sdcard *the rest*
thanks in advance
sounds like you tried to repartition from Android
You need to boot to CWM - you have parted there.
Sorry I hate people who just ask stupid questions before reading the instructions carefully ...silly me sorry for that...
What about the second question, is it possible to either increase the data partitions for less space on /sdcard ?
there isn't sth. like a data1 partition. we have one data partition only that's why we need the TDB hack.
other than that it's possible but you should backup all your data and restore it afterwards.

parted -s /dev/block/mmcblk0 name 27 storage || return 1
return 0
}
Code:
ui_print "format partitions"
for NUM in 23 24 25 26 27
do
if ! format_partition "$NUM"; then
ui_print "Failed format partition $NUM"
exit 1
fi
done
already did full backup of sdcard, i just dont know if i should disable TDB before i stat repartitioning ... I dont know how TDB works to split the data partition thats my problem :/
yes that should work.
You don't need to disable TDB because your whole data partition will be wiped and it stores the TDB configuration(that means that TDB automatically gets disabled).
Had some errors but now its working fine ..thanks
unmount sdcard in CWM. It's a bug of this script.
Nice to hear it works now.

Hello
First do not panic is not the fault of your script but for you experience with mi2s and partitions are the few people in the world that can save my phone.

Can you explain a little more? Does it only leave 1 system partition? Can I flash it like a regular zip?
Enviado desde mi MI 2S mediante Tapatalk
any step by step manual how to change partition? with all necessary downloads etc...
or.... is it possible to delete system2 with all its parts? - for me I'd to use system1 only
Why can not I change the size of the system partition?
Already tried several times, with disabled TDB and with enabled TDB.
Full wipe did and still no result.
P.S. I have already been able to do any repartitioning.

PS C:\Android> adb reboot recovery
PS C:\Android>
UPD. The problem was that I was using Windows Povershell
Run the script from the command line and everything turned out.
Thanks!
I have to format first system and system1 in recovery to apply this script, because I have and error :
tmp/repartition.sh lin 115 can´t create /sdcard/parted_12_06_2014_FDFD6F4CB043F4956D9CAD053C3738AA.
DO MOUNT your SDCARD
then Follow the instruction
duhh...
I modified the script a little bit for 1 ROM usage. System1 is 840MB as in the original and System2 is 5MB. The rest goes into userdata. This is for the 16GB version.
Ok! I did again and umount the sdcard abd it worked fine.
Thanks
I found a better way
If u reboot into dload mode, u can change the partition table from your computer
The problem is that most partition managers don't support changing the GPT Partition names and that's why I added support for that to GParted.
GParted supports booting from Live CD/USB so Windows/Mac users aren't left out.
http://i.imgur.com/3SwSXs2.png
I pushed the patch to GParted repo's and I'll inform u once there're any news.
from my point of view the best way for use is:
- system (system1) - let 1024 MB
- system1 (system2) - let 10 MB
- userdata (apps) - let 4096 MB (take it from sdcard) - but maybe more

How to resize a partition table ?

I'm trying to fix my messed up partition table in my Meizu 5 PRO for Ubuntu Touch installation.
Using ADB and fdisk I've managed to get this print out:
Code:
~ # fdisk /dev/block/sda
Note: sector size is 4096 (not 512)
Found valid GPT with protective MBR; using GPT
Command (m for help): p
Disk /dev/block/sda: 122142720 sectors, 1984M

Partition table holds up to 128 entries
First usable sector is 6, last usable sector is 15267834

44 55808 65535 [B]38.0M 0700 userdata[/B]
I bolded partitions in question. Cache is taking up all the storage whereas "userdata" gets only 38MB. I need to resize "userdata" partition to take up most of the storage and leave about 2 GB for cache. I noticed cache partition is formatted in ext4 and "userdata" is vfat.
option "d" selects partition 1 for some reason.
after running
Code:
disk /dev/block/sda43
(which is the partition with 60GB) I get:
Code:
Command (m for help): p
Disk /dev/block/sda43: 59.0 GB, 59047391232 bytes
64 heads, 32 sectors/track, 7038 cylinders
Units = cylinders of 2048 * 4096 = 8388608 bytes
Device Boot Start End Blocks Id System
Someone more experienced, can you guide me ? I don't wanna mess it up more than it is.
Thank you in advance.
Update:
Have learned that the best tool for resizing a filesystem is resize2fs thus I ran:
Code:
~ # resize2fs /dev/block/sda43 1G
However even after resizing the filesystem to 1GB I still get:
Code:
43 851968 15267834 [B]54.9G 0700 cache[/B]
Shouldn't it be reading 1GB now ???
Oh boy. Maybe parts of this guide could help you:
https://forum.xda-developers.com/meizu-pro-5/how-to/tutorial-how-to-upgrade-to-ubuntu-touch-t4021397
You *need* the correct fdisk version for this, as stated in the guide.
Do not just copy the bold parts. Sectors for your current table are below the next code box):
Code:
Command (m for help): d
Partition number (1-3,21-33,43,44, default 44): 43
Partition 43 has been deleted
Command (m for help): d
Partition number (1-3,21-33,44, default 44): 44
Partition 44 has been deleted.
Command (m for help): n
Partition number (4-20,34-40,43-128, default 4): 43
First sector (6-15267834, default 1769472): [B]1769472[/B]
Last sector, +sectors or +size{K,M,G,T,P} (1769472-15267834, default 15267834): [B]2293775[/B]
Created a new partition 43 of type 'Linux filesystem' and of size 2 GiB.
Command (m for help): n
Partition number (4-20,34-40,44-128, default 4): 44
First sector (6-15267834, default 2294016): [B]2293776[/B]
Last sector, +sectors or +size{K,M,G,T,P} (2293776-15267834, default 15267834): [B]15267824[/B]
Created a new partition 44 of type 'Linux filesystem' and of size 49.5 GiB.
When creating partition 43 sector should be first 851969 - last 1376271 for 2GB cache
and for partition 44 first 1376272 - last 15267824 to assign the remaining space to userdata.
Next change the partition types to "Microsoft basic data"
Code:
Command (m for help): t
Partition number (1-3,21-33,41-44, default 44): 43
Partition type (type L to list all types): 11
Changed type of partition 'Linux filesystem' to 'Microsoft basic data'.
Command (m for help): t
Partition number (1-3,21-33,41-44, default 44): 44
Partition type (type L to list all types): 11
Changed type of partition 'Linux filesystem' to 'Microsoft basic data'.
Check again with "p", if the types are correct. If not, search correct type number with "t" and "L" and try again.
Afterwards, you need to continue to give the partitions names:
Code:
Command (m for help): x
Expert command (m for help): n
Partition number (1-3,21-33,41-44, default 44): 43
New name: cache
Partition number (1-3,21-33,41-44, default 44): 44
New name: userdata
Expert command (m for help): r
Command (m for help): w
The partition table has been altered.
Calling ioctl() to re-read partition table.
If the table has been successfully altered, you can now continue to install the filesystem:
Code:
~ # mke2fs -t ext4 -m 0 /dev/block/sda43
~ # mke2fs -t ext4 -m 0 /dev/block/sda44
This should fix your current dilemma. Its a lengthy guide and if you actually want the most recent ubuntu touch you might as well do it completely, resizing your system partition too. In that case ignore above changes.
