Installing ROOT Help

ok i got this far
8. Type the following into Telnet (these commands will give you root access easier in the future):
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
cd sdcard
flash_image recovery recovery.img
cat recovery.img > /system/recovery.img
and on the last command i get a error "cannot create /system/recovery.img"
am i rooted already ????? or what needs to be done please help...
files i have on sd card are recovery.img and update.zip

read the threads and follow them step by step....STEP by STEP....

Verify that you command prompt has a "#" in front and not a "$"
# = root
$ = user.
make sure you type in mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system exactly like that. and be sure that it does not return any errors.
again type these in EXACTLY as shown.
cd sdcard
flash_image recovery recovery.img
cat recovery.img > /system/recovery.img
if you still have the problem, please respond.

i am following everything step by step and cant get it i just get cannot create recovery.img read only file system

if its not working then you arent following the steps correctly.

cat recovery.img > /system/recovery.img
i get this after ## is that a good thing???

if you are using the crappy built-in windows telnet client.. it will appear like this:
Code:
# # mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# # cd sdcard
# # flash_image recovery recovery.img
# # cat recovery.img > /system/recovery.img
# #
i recommend you use putty. Putty Homepage
this provides a cleaner telnet interface.
but yes.. that means it worked!
EDIT:
Now to explain just a bit what just happened:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system :: this mounts /dev/block/mtdblock3 in /system (lots of fun stuff available here, but i recommend you leave that to developers
flash_image recovery recovery.img :: this flashes the recovery image with JesusFreke's custom recovery image.
You should now proceed to downloading a modded RC30 (also available on this forum) and place it in the root of your SD card. Rename it to update.zip and turn off your phone.
Press (and hold) the Home and Power(red) keys until you see the recovery screen. Now slide out the keyboard and press ALT+S.
After it's complete press ALT+W, and reboot.
WARNING: this will wipe out all previous custom settings and restore you to factory defaults!

Ok, so I've decided I want to root my G1 too, and I'm having a similar problem. I broke my first G1, huge crack on the screen, but still functional. I have a replacement in hand, but want to test rooting on the old one so I don't risk the new one till I know I get it right. I had OEM RC30 installed and flashed down to OEM RC29. No problems there. Then I restarted, following instructions to the letter. Typed in "telnetd" :enter: No problems there. Downloaded Telnet app from the market and connected to local host on port 23. No problems. I even had the ## prompt. After typing in the commands listed in the tutorial with no problems, I installed HardSPL and update.zip into the sdcard and did all that. Then I upgraded to JF RC30. Now when I open the Terminal Emulator program, I get the $ prompt. What did I miss? Should I flash back down to RC29 and try again? I think I will just in case I'm an idiot, which is entirely possible.

type su in the terminal emulator. you'll get the # prompt.

Right... I'm just stupid. So I'm running 1.41 on my old G1 now. Nicely done, it feels just like the ota version (no hiccups or bugs so far) and I have multi touch. You're awesome jf!

or do it through pc like intended.. and remount

am having this problem but it says
recovery.img: no such file or directory
##
i am using rc8 uk model please help

For those still having trouble rooting there is an app that can root your G1 with "1 click", that's not what I used to root my phone but I hear it works I bet if you look for it you'll find it

Urgent Help required Rooting

Hi Guys,
I am having a problem with rooting my G1, For the last hour I have been stuck at the point where I have downgraded the phone to the RC7 successfully and am trying to press enter twice and type the telnetd.
At this point I'm not sure if it should give me a sign that it has worked but I then goto telnet command prompt which is showing some questions marks them the # sign but when I type in the commands from the instructions the following happens: Typed exactly as it appears on my screen
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# #cd sdcard
# #flash_image recovery recovery.img
No such file or directory
# #flash_image recovery/sdcard/recovery.img
usage: flash_image partition file.img
# #cat recovery.img > /system/recovery.img
recovery.img: No such file or directory

Try reading this: http://forum.xda-developers.com/showthread.php?t=442480
Its sounds like you havent put the recovery image in your sdcard.
read the instructions again.

I placed the recovery image and the zip file in the sd card, but i was thinking of sacking this method and trying the root.apk method.

rename cm-recovery-1.4.img to recovery.img on your sd card
-OR-
flash_image recovery cm-recovery-1.4.img

The file is called recovery.img

Ok I rebooted the phone pressed enter<reboot>enter again and the phone rebooted, so now I have root what next, do I need to do anything else before putting on a rom, what rom should I put on?>?????

Problems getting into recovery image on rooted Nexus

Hey guys,
I rooted my Nexus one but I have a small problem getting into the recovery image.
In the modaco instructions you have this red text
Check if there's no /system/etc/install-recovery.sh script if you keep booting back in the stock recovery (exclamation mark with a little Android).
This is exactly what is happening to me and all I would like to know is....
How can I make this exclamation android disapear?
The file /system/etc/install-recovery.sh is there... but can I delete it or modify it somehow?

Why not use fastboot and flash the recovery?

I actually tried to do that but I have the same problem when trying to boot up in recovery.

Actually finally managed to get into the recovery image just now after using fastboot to flash the image once again.
However after rebooting the phone I still have the same problem. So basicly, this works if I just flash it, power off phone and run the custom recovery image. After that I get the little android with the exclamation mark.
Just to show what I do when flashing the reccovery image.
Superboot aquired
Code:
- MAC - Open a terminal window to the directory containing the files, and type 'chmod +x install-superboot-mac.sh' followed by './install-superboot-mac.sh'
I get success on this and my root access seems to work. (I am only running Market enabler to make it work)
Code:
Copy recovery-RA-nexus-v1.7.0.1.img to a location where fastboot can find it. ( Put this in my home folder under superboot\recovery-RA-nexus-v1.7.0.1.img
Boot your phone into fastboot mode (power on while holding the trackball)
Connect your phone via usb to your [B]MAC[/B]
./fastboot devices (to make sure that fastboot "sees" your phone)
./fastboot flash ./recovery recovery-RA-nexus-v1.7.0.1.img
So, I continue... Any idea why I am still getting the little Android? I have

same problem with me i can not do it!

Well look no further becouse I have found the solution to our problems.
Superboot again and start with
Code:
adb shell
$ su
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
Then you type
Code:
rm /system/etc/install-recovery.sh
Now follow instructions to install the Recovery image
After this you will hopefully not have any problems

help
sorry to bring this back... but, i need some help here...
when i enter $ su... i get "permission denied"

You need to have root access, google it or look in the development section for guides.

Cannot remove /system/etc/install-recovery.sh
Nexus One FRF91, unlocked and rooted.
SDK and USB driver installed, Windows XP.
Using ConnectBot I can see /system/etc/install-recovery.sh is present
I recovery boot into RA-nexus-v1.7.0.1
fastboot and adb both see the device.
adb remount returns remount failed: Invalid argument
If I go into adbshell and try mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system I get failed: Invalid argument
Have I missed something?
Any help would be most appreciated!

I can work around it with adb shell, still puzzling why adb remount will not work though...

Hi Jakk,
I'm not a developer, but, the error seems indicate that adb can't remount as RW the /system, so:
1) adb shell work? (you must see a "#" if you are root)
2) have you installed busybox?
3) the 01newcache script in init.d directory work if you have a rom/kernel that suppor init.d
I use the script and i can confirm that work very fine
Bye
Idk

1) How am i able to see that? Should i see a # at the ADB CMD box? Root checker veryfies that my device is rooted.
2) Yes it's installed using V1.16.2androidminimal - updating now.
3) How can i check if my ROM supports that? My rom is the Stock safe Rom provided when flashing to Overcome.

Using the "adb shell" command in ADB gives me a $

using the adb shell command gives me the $ as i said.
When using the command su it gives me the # you're where talking about.

Hi Jakk,
Yes, so you have a working superuser thats ok, but if you have stock kernel (i think) there isn't any init.d support so the only way is to try manually.
Another way is installing a custom rom (boca, overcome, etc..) or custom kernel that have init.d support.

Hmm actually not sure that there is a custom kernel installed (i don't suppose since it's a stock firmware, then the kernel should be stock - dosen't allow me to overglock however xD )
I've get this message:

Hi Jakk,
1) adb is use only from PC (windows or linux), there isn't any adb command into android OS...
2) My mistake: read this links: http://android-tricks.blogspot.com/2009/01/mount-filesystem-read-write.html and http://forum.xda-developers.com/showthread.php?t=685146; the above command is about rfs (Samsung Robust File System); if you have converted the filesystem into ext4, i'm not sure that above command work....
sorry

Hi,
if you try the adb into android phone shell, simply don't work because adb is a windows command (adb = android debug bridge).
The good is seems you have the init.d directory, so try this:
go to android phone shell and remount /system
in a windows cmd shell do this:
adb push 01newcache /system/etc/init.d/
return into android phone shell:
adb shell
cd /system/etc/init.d
chmod 777 01newcache
ls -l /system/etc/init.d (to show the contend of init.d)
exit
Bye

So you mean that i'll just simply open a cmd box without refering to adb and then use the adb push 01newcache /system/etc/init.d/ command? How's that gonna work?
If you've got the time could you please assist me over teamwiever or something similair?

pretty skilled, gonna start my IT-technician education after christmas, and i've know a bit bat programming from working with windows server and also a bit html and php.
capable of flashing ROMS, unbricking etc but haven't used ADB before. I've configured adb the exact same way as the tut you've sent me.
However i still just get's error codes like adb not found, remount not found, Is a directory, or are you sure you are rooted?

Is working ?:
Code:
adb shell
If yes then:
Code:
su
mount -o remount rw /system
then - if you are not able to use "push" - copy the file in your SDcard then, while in adb shell:
Code:
cp /sdcard/yourfile /your-destination/
Seem easy

then which one am i going to choose? The overwrite?
and am i just supposed to write it like this:
cp /mnt/sdcard/01newcache /system/etc/init.d/
Because then i've get a cp can't create /system/etc/init.d/: Is a directory

Try this:

Bye

If you have the init.d folder then just manul copy "01newcache" to your sd card and from your tab, with a root explorer (i use esfile explorer with root option enabled from option menu) copy it to system/etc/init.d.

...to solve the original problem...
I fixed this on my device from a windows command prompt by typing "adb root" , which restarts the daemon on the device with root permissions.

[GUIDE] Making Dump Files Out of Android Device Partitions

Use:
The main purpose is to make a file that contains all data in android specific partition. This is really handy in case of dumping leak firmwares.
Pr-requirement:
- Rooted device.
- Knowledge of how to use adb or Terminal Emulator.
The first step of making dump files out of device partitions is to locate its mounting points..!!
So in our tutorial, we will make it in 2 sections. Section 1 for how to get mounting points, and section 2 for how to get partition dumped..
Keep in mind that this is xda-university; so my target is to show beginners how to do that manually, without the aid of any tool, so they can get the concept behind it.. OK let's begin..!!
Section 1:
Getting mounting points​There are several methods to achieve this, but we will discuss the easiest methods that give efficient information about the partition that you want to know its mounting point.
All these methods will be described using adb shell.
Way #1
Code:
adb shell
cat /proc/partitions
This one needs from you to figure out which block belong to which partition name.!!
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Way #2
Code:
adb shell
ls -al /dev/block/platform/[B][COLOR="Blue"]dw_mmc[/COLOR][/B]/by-name
This one will give you info about the dev block names WITH their familiar names (i.e, boot, recovery, system... etc)
This command is not universal between devices, and you will need to gather its pieces (/dev/block/platform/dw_mmc/by-name).
How?
- In your device, use any explorer that can get you to the device root (personally I use ES Explorer, by pressing on "/" on navigation bar).
- Go to "/dev/block/platform/" folder
- Here you will see some files and folders, we need to open folders and search for the folder called "by-name" inside one of them; in my situation it was "dw_mmc" folder which has the folder "by-name" inside it.
- At the end, my targeted piece info will be (/dev/block/platform/dw_mmc/by-name)
- Now open adb shell and put that command..
Way #3
By pushing parted binary to /system/bin folder and run it (you can find it in attachment).
Code:
adb remount
adb shell "su" "" "mount -o remount,rw /system"
adb push parted /system/bin/parted
adb shell
chmod 0755 /system/bin/parted
parted /dev/block/[B][COLOR="Blue"]mmcblk0[/COLOR][/B]
print
Here, your mounting points will start with /dev/block/mmcblk0p* where (*) is the number shown in the table above for each partition.
example:
The hidden partition mounting point will be mmcblk0p10
The radio partition mounting point will be mmcblk0p7
The system partition mounting point will be mmcblk0p9
The recovery partition mounting point will be mmcblk0p6
and so on
Don't forget to "quit" the parted action after grasping your device mounting points.
N.B:
- You may need to run first:
Code:
adb shell
cat /proc/partitions
to know what is the initial name for your device partition.. In the example above, it was mmcblk0.
- Also to be able to do adb push to /system partition for parted binary, you will need insecure boot.img used in your ROM or adbd insecure installed in your device (Check this thread for that app), or just push parted binary manually by any root explorer and then fix permissions to rwxr-xr-x (755).
***​
Section 2:
Dumping ROM partition​After locating the mounting point of the partition you want to dump, open adb shell command prompt and type:
Code:
adb shell
su
dd if=[B][COLOR="Blue"]/yourMountingPoint[/COLOR][/B] of=[B][COLOR="Green"]/yourDestination[/COLOR][COLOR="Red"]/partitionType[/COLOR][/B]
Let's say I want to take a dump out of system partition from above example. So the adb commands will be:
Code:
adb shell
su
dd if=[B][COLOR="Blue"]/dev/block/mmcblk0p9[/COLOR][/B] of=[B][COLOR="Green"]/sdcard[/COLOR][COLOR="Red"]/system.img[/COLOR][/B]
This may take a while to complete the dumping process, depending on the size of your dumped partition; so be patient..
Note:
If the partition is formatted as ext3/4 then the dumped partition will have .img as an extension.
Other partition dumps have different extensions; examples:
radio.bin
param.lfs
Sbl.bin
zImage (without extension)
***​
Optional:
Read Partition Image​After dumping an image from android partition, you can mount it to extract a particular file for sharing, or the whole dump content in case the ROM chief wants to make a ROM out of dump files..
For Linux Users:
- Open terminal and type:
Code:
su -
mkdir -p /mnt/disk
mount -o loop [B][COLOR="Red"]yourImage.img[/COLOR][/B] /mnt/disk
cd /mnt/disk
ls -l
For Windows Users:
- Download LinuxReader from this site here.
- Open it -> Drives -> Mount Image -> Then choose your dumped image and hit Mount. A new driver will appear that contains all files inside the dumped image called "Linux native Volume 1". Just double click it to get inside the dumped image.
I hope you will find this tutorial beneficial,,,
Yours;

Code:
chmod 0755 /system/bin/parted
chmod binary is used to set permissions for the specified file/dir.
The number after chmod is the permission used. See the next box for better understanding of chmod formatting:
Code:
[CENTER][B][COLOR="Red"]----------------
| CHMOD SCHEME |
----------------[/COLOR][/B][/CENTER]
[B] r w x[/B]
[B]4 2 1 [COLOR="Green"]= 7 (Full Permissions)[/COLOR][/B]
User ( ) ( ) ( ) [B][COLOR="Green"]--> 2nd digit[/COLOR][/B]
Group ( ) ( ) ( ) [B][COLOR="Green"]--> 3rd digit[/COLOR][/B]
Other ( ) ( ) ( ) [B][COLOR="Green"]--> 4th digit[/COLOR][/B]
Special UID GID STK
( ) ( ) ( ) [B][COLOR="Green"]--> 1st digit, ignored on most cases or put 0[/COLOR][/B]
In the above example, it is set to 0755 which means the following scheme:
Code:
[B] r w x[/B]
[B]4 2 1[/B]
User ([B][COLOR="Red"]*[/COLOR][/B]) ([B][COLOR="Red"]*[/COLOR][/B]) ([B][COLOR="Red"]*[/COLOR][/B]) [B][COLOR="Green"]--> This equals to 7 (rwx)[/COLOR][/B]
Group ([B][COLOR="Red"]*[/COLOR][/B]) ( ) ([B][COLOR="Red"]*[/COLOR][/B]) [B][COLOR="Green"]--> This equals to 5 (r-x)[/COLOR][/B]
Other ([B][COLOR="Red"]*[/COLOR][/B]) ( ) ([B][COLOR="Red"]*[/COLOR][/B]) [B][COLOR="Green"]--> This equals to 5 (r-x)[/COLOR][/B]
Special UID GID STK
( ) ( ) ( ) [B][COLOR="Green"]--> This equals to 0 (---)[/COLOR][/B]
As you can see, if you said 0755, it will be as same as saying ---rwxr-xr-x

if you mean extract to modify boot.img, then I don't think there is away to do that from device itself in the moment..
if you mean dumping boot.img then yes you can, just install terminal emulator from Google play and you can run adb shell commands directly from the device

Great guide hopefully makes it easier for us to get dumps! if you add logcats etc, i find they have trouble executing "adb logcat >> log.txt" -.-
also you should teach them the easy tar method, so while booted "tar -c /system/* >> /sdcard/system.tar" or via adb shell

Yup that is possible and easy to extract but it is only for partitions that is shown in android os,,, you can't use it for boot.img, sbl.bin, modem.bin...etc right

ofcoarse, i actually had a project going where it detects all partitions(modems, boot.img, system etc..) that archives itself into a .zip
it was going well until i did something in the script, now it only works on the s3 it shall be continued one day!

Such great tutorial, this is definitely going to come in handy for me. I have a question, how can you dump (extract) a bootloader? Can i use the same method as dumping the ROM?

Could you explain how to extract stock recovery image please?

Thx for this. On my HTC One there is no "by-name" folder. It only has "by-num". cat /proc/emmc works fine though.
Cheers.

I also wrote a guide, It just using the "by-name"
and needs root
[HOWTO] dump your rom
Code:
dd if=/dev/block/platform/msm_sdcc.1/by-name/system of=/storage/extSdCard/system.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/recovery of=/storage/extSdCard/recovery.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/param of=/storage/extSdCard/param.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/boot of=/storage/extSdCard/boot.img

Hi,
I tried this on my I-9505G. It is NOT rooted, so I thought I could enter the system through Clockworkmod Recovery.
I did it, but at first I didn't mount the DATA partition (later on I did through CWM Recovery); I still ran the command:
dd if=/dev/block/platform/msm_sdcc.1/by-name/system of=/data/media/TEST/system.img
Thought I hadn't mounted anything, the media folder was still there, I only created the TEST folder.
After the image was created I typed the "ls" command and the system.img file was in /data/media/TEST/.
I then rebooted once again in CWM and ran the "adb shell" command once again, I entered /data/media/ e neither the img file nor the TEST folder I had created were there.
My question is: where have they gone?? Are they still occupying some of my space or they just got deleted automatically when I rebooted??
Please let me know as I'd like to free that extra unuseful 1.2 Gb system.img file.
Anyway, just as side information, I later on mounted the /data through CWM interface and was able to see the folders ("/data/media/0/") I can see by plugging the phone normally to the computer. I then dumped the image.
I have some other questions:
I can I mount the /data folder (or the external SD) via command?
What extention should I give to the other partitions? (All of them)
Why did you say that it's MANDATORY that the phone be rooted if it can be done this way?
Are the images I'm dumping flashable through fastboot?
Thank you all for your time!

Anybody? Please.

•I can I mount the /data folder (or the external SD) via command?
I have not been able to find the SD card in clockwork on the I9505G, hence one of my rooting procedures send the root file vi "adb sideload".
I might be able to pull the data from the phone but the clockwork recovery is still not working 100% when fastbooting it.
•What extention should I give to the other partitions? (All of them)
.img are fine.
•Why did you say that it's MANDATORY that the phone be rooted if it can be done this way?
currently it is required that the phone be unlocked. Something need to be fixed in clockwork to make it work any other way.
•Are the images I'm dumping flashable through fastboot?
They should be, but I have not been able to flash anything on the I9505G vi fastboot because of the secure boot.
without a full official image this make my playing around a little concerning (slowing me down).
I will look into this at my leisure. I would love to be able to pull a rom off a phone with only unlocking it.
I will test some stuff using my old galaxy nexus.

I actually dumped everything WITHOUT being rooted. I only unlocked the bootloader... So it works.
Further, I tried to run "fastboot boot recovery.img" with recovery.img being the image file I dumped. The phone froze and I had to pull the battery... So I assume they're not flashable as well, though I'd like other feedbacks.
I've not clearly understood what "secure boot" means. Any guide or wiki?
Thanks!

Hey, great guide! I need some help but. I can't retrieve the common names / labels of my devices partitions. It's a GT-i8150 and there is no 'by-name' sub directory. Furthermore, parted does not work on mmcblk0 for some reason (unable to satisfy partition restraints or something). I also have no emmc file in proc.
Does anyone know how some other methods for getting the names of the partitions?
EDIT:
Another question - using ADB shell, is it possible to dump a partition straight from the phone onto the computers hard drive? My little 2GB sd card isn't coping! Thanks

a very basic but good guide
