1. How can I root my phone?
1.1 General information/Basic adb-commands
Rooting a phone enables you to do things, which normally aren't possible for the average user like:
- Removing apps which were preinstalled by the provider (like Orange, Vodafone, etc.). My Tattoo had Vodafone apps for buying music and other sh*t, which was installed on the system partition (to which a "normal" user has no rights to write to, including deleting).
The Tattoo was successfully rooted by a bunch of guys here, namely -bm-, mainfram3 and Coburn64 (maybe, I don't remember quite correctly ). Also the Tattoo was the first phone having a security mechanism hindering a user to mount the filesystems as read/write, which had to be overridden by remapping the read only memory region to a read/write one. This is done by the module Tattoo-hack.ko, also made by mainfram3. He also created the first boot.img, which enabled su directly from adb and loading Tattoo-hack directly from boot on.
A few words about adb:
ADB is a tool for communicating from the PC with the mobile phone. For this a service is running on the phone enabling the communication via Terminal Emulator. Here are the most useful adb-commands:

Code:
adb push localFileFromPC /path/on/mobilephone
-> pushes a file "localFileFromPC" to a specified location on the phone
adb pull /path/to/file pathFromPC
-> receives a file from the phone and stores it to "pathFromPC"
adb remount
-> This is only possible in custom ROMs, remounts the file system to r/w automatically
adb shell "command"
-> executes "command" and returns to the computer shell
adb shell
-> opens a shell session on the phone (from here on you have to be very careful! Also you can execute now normal linux commands like rm, mv, ls, chmod and so on, but not cp (this can done through busybox)). You will have to use this more often, so get used to it ;)

[Q] [Help]

Hey i have really messed up my nexus 4.Please help.I'll tell you my problem in short:I have flashed recovery.img onto userdata by mistake using quikIMG.So now the phone got reset and the whole phone was seemed wiped.There was nothing on the phone.Thats what i assumed after peeking into galary/music etc but when i connected my phone to the pc it is showning that the phone's 10gb is used.Basically it is showing that the data is still there.Can you tell me any way to bring back the data?

Try factory reset

This may or may not work, no guarantees. This will be difficult, time consuming, and you must do everything exactly as written; so read it first and ask questions before you begin. I am using a Windows PC, most of these commands will be similar on other OS's, those when in the adb shell are identical. This will require adb and a custom recovery (I use TWRP, so I'll be able to offer TWRP specific help quicker), find a method to flash that before you begin, and find where that recovery keeps it backup files. Also this will require you to flash a rooted ROM, of the same android version you had before: if you had stock, I recommend you flash stock and root it; either way, have that ready to go before you start. Lastly, the worst case scenario will require you to have a linux system and possibly some kind of removable media (USB stick, external HDD, etc), you can just boot a linux live disk, and that's what I'll be doing with Ubuntu; again, have this ready first. There will come a point about mid way through, where, depending on the results you may need to wait for me to follow up with you, I will try to do this in a timely manner, but I can't promise anything.
Basically what we are going to do is explore the file system in an adb shell while it is booted to a custom recovery, hopefully from there your /data and /sdcard partitions will still be intact; if they are not we may still be able to recover some of your data. If they are intact you can simply use the recovery to make a backup of them.
And so, with your phone connected to your computer, boot to recovery. Then open a command prompt and enter:
Code:
adb shell
cat /proc/mounts
The output will look like:
/dev/block/mmcblk0p23 /data ext4 rw,relatime,data=ordered 0 0
/dev/block/mmcblk0p23 /sdcard ext4 rw,relatime,data=ordered 0 0
/dev/block/mmcblk0p22 /cache ext4 rw,relatime,data=ordered 0 0
Click to expand...
Click to collapse
First is the block, then the mount point, then the file system type, last is information about how recovery treats it.
If you do not see /dev/block/mmcblk0p23 associated with a mount point then enter:
Code:
mount -o rw /dev/block/mmcblk0p23 /data
mount -o rw /dev/block/mmcblk0p23 /sdcard
If you get an error on both of these then skip to the breakt.
Now check both these directories to ensure it is the data you expect it to be, enter:
Code:
cd /data
ls
cd /sdcard
ls
Maybe go down a few levels to confirm your data is really there. If the output doesn't look right, then skip to the break.
Otherwise, enter:
Code:
exit
Use the phone screen to navigate to the backups menu and backup data.
When the backup is complete use adb pull to copy the backup onto your computer, this may take a very long time.
Code:
adb pull /sdcard/TWRP TWRP
Now flash your ROM, including a data wipe, and boot it, once it is running fully, reboot into recovery and push the backup to the phone.
Code:
adb push TWRP /sdcard/TWRP
Use the phone screen to restore the data.
--------------------THE BREAK, cause XDA automagically made these two posts one, ****ers--------------------
Hopefully you got this sorted out with the first part, this part may not work at all, and it will be a lot more tedious if it does. So, at this point something happened which indicates /mmcblk0p23 really did lose the data, so we'll just copy the whole thing and explore that copy in linux to extract what data you can.
With the phone in recovery, and a command prompt in an adb shell:
Code:
dd if=/dev/block/mmcblk0p23 of=/tmp/userdata.ext4
This may take a REALLY long time. When it is done, enter:
Code:
exit
adb pull /tmp/userdata.ext4
This will take just as long or longer. Transfer userdata.ext4 to your removable media device. And boot to your linux setup. Open a terminal window in the directory with userdata.ext4 enter:
Code:
sudo mkdir userdata
sudo mount -o loop userdata.ext4 userdata
cd userdata
ls
Now if any of your data still exist in a form I'd be able to help you recover, it will be in this directory, userdata. If you see something that you recognize, or that you know you need, copy it and save it to the removable media. After that you can reboot your system.
Go ahead and flash your new ROM now, let it fully book, and then copy back whatever you managed to save.
I kinda lost steam there toward the end, sorry, it's 0316 here. If anything is unclear ask away. Good luck.

[Q] How do I install parted command?

I'm trying to wipe and format a microSD card that I have plugged in via OTG and already have it wiped with this;
Code:
dd if=/dev/zero of=/dev/block/sda
Now I'm looking into how to recreate a MBR and partition table and it says to use the parted command, which I'm glad about as I'm familiar with the command from using Ubuntu but it's not installed and I can not find any instructions on how to get it. Can anyone explain how to install it? I know I could just plug the SD card into a computer and do it but I'm having fun doing all this on a tablet. Lol

Bump
Anyone?

I have got the same question, any other solutions?

This is the most complete information I have found yet, but it doesn't work. Either from me messing something up or it not being correct for the Nexus 7 being that it was made two years ago. http://www.droidforums.net/forum/htc-droid-eris/78650-internal-storage-partitions-screwed-up.html
I pushed all six files to /sbin/ with no errors and changed their permissions with no issues but I restart the tablet and none of the six files are in /sbin/

Just for the heck of it I extracted the six files to the SD card in the tablet, CD'd to it and used chmod 0755 on all six files then tried to run it and this is what I get.
Code:
[email protected]:/storage/emulated/legacy/folder # parted
sh: parted: not found
127|[email protected]:/storage/emulated/legacy/folder # ls
e2fsck
mke2fs
parted
resize2fs
sdparted
tune2fs
... how can you NOT find that?

Depending on how your PATH env var is set, the current directory might or might not be being searched for program load(s). So indicating the current directory explicitly with a leading "./" such as
$ ./parted
will certainly work (if a read & execute bit set on file, and the filesystem is not mounted -noexec ) .
But...
...if those files are dynamically linked rather than statically linked, and the appropriate link-libraries they reference come up missing during run-time linking it is possible to still see a "not found" message. Sort of a red-herring error message, but there you go.
I just looked in TWRP's /sbin (ramdisk) just now. Don't see parted in there.
[Edit] I do see the string "fdisk" inside the busybox executable though! - maybe boot into recovery and see what
busybox fdisk /dev/block/sda
gets you? (I suppose result depends on whether or not TWRP kernel plumbs the device into place.)
Perhaps the quickest solution is to simply use a PC and media reader to do the partitioning from a PC instead of the N7. You might even want to boot a "Live CD" version of Linux to get at the tools you need. (BTW, I think that Ubuntu's Live CD mounts a fuse FS over the top of the RO DVD/CD, so you can even download and install packages as needed).

I managed to get everything to work by doing this:
1. Using this app https://play.google.com/store/apps/details?id=com.beansoft.mount_system&hl=en I remounted /system as RW
2. Using the CyanogenMod File Manager I copied the parted file to /system/bin (from the root of the SD card)
3. Then using the File Manager still, go to the Properties of the parted file and go to Permissions and under R, W, and X put a check mark in the three boxes bellow each. (I don't know which ones it needs permissions for so I just give it permissions to everything, kinda frowned upon to do but I trust this program so...)
By doing this you can completely stay out of command line, but at the same time you're installing a command line program so you shouldn't be afraid of the command line in the first place. Lol.
Note: After this you can go to a terminal window and type su to get root access then type
Code:
parted /dev/block/sda
you will of opened your external memory card, now use parted as you would normally.

Any Data Recovery tools usable with ADB shell?

I'm looking for any 'file carving' tools like foremost or scalpel that are built for android and can be used inside ADB shell the same way busybox is. I only have access to recovery and cannot write to the userdata partition, but can write anywhere else, like system.
Thanks

How to Recover Files After MSM?

Hi all,
I bricked my OP6T with a ROM update and had to run the MSM tool. Unfortunately, I seem to have lost all my photos. However, I have imaged the partition using the below shell commands and plan on using a recovery tool to get the images back. However, will the data be encrypted? Is there a way to retrieve the key or wrapped key for data decryption?
I also have a backup of modem files if that helps.
Code:
su
mkfifo /cache/fifo1
ftpput -v -u .. -p ... 10.0.0.2 /backup/sda.img /cache/fifo1 & dd if=/dev/block/platform/soc/1d84000.ufshc/sda of=/cache/fifo1
