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

Trying to get root access

I can enter the first two commands, mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system,flash_image recovery recovery.img and cd /sdcard but when i type in the last command i get this
cannot open /system/recovery.img no such file

Don't know what you're typing there.. missing some stuff.
Try this:
Code:
mount -o remount,rw /dev/block/mtdblock3 /system
cd /system
cat /sdcard/recovery.img > recovery.img
flash_image recovery recovery.img

Did you type SU before??

i did what the first reply did. what do you mean su?

i got it thanks

SU = root access.

Once you have rooted your phone and installed a custom image, you need to type "su" and press enter anytime you go to the command prompt to do something requiring root. Basically root is disabled by default so you don't break things - you need to specifically tell the phone you want root access to try and avoid breaking things by mistake.
Anyway, glad you got it working.

No that will not work. pm me and I will fix it with you on gtalk.

Since you ran the test ruu you do not have flash_image on your phone. You need to push flash_image to /system/bin/flash_image. I will attach it as a .zip below. Put the .zip in your sdk folder then follow these adb instructions to rename and push it:
Code:
adb remount
adb push flash_image.zip /system/bin/flash_image
Be sure to type it as above to correctly rename it..it is not really a .zip but XDA forces the rename to attach..
You have to give flash_image permission now, so type this:
Code:
adb remount
adb shell chmod 0755 /system/bin/flash_image
Now you should be able to flash the custom recovery if you have indeed rooted your phone and gave permissions to flash_image.

Thankyou thankyou thankyou

I am pretty new to this, so it is case sensitive? I will try and see.

jeez guys. just plug your phone into your computer and drop the heroc-...img into your sdcard's root folder.
then:...\tools> adb shell
ls (to see what's in your current directory)
cd sdcard (to hop onto your sdcard)
su (if not already root)
flash_recovery recovery-.......3.img
reboot recovery

It is the command "flash_image" that is not found - not the img file
I have the same problem - but in posting it I see that everyone is looking at the error as though it relates to9 the img file

Here is what you need to do
Code:
adb shell
cd sdcard
flash_image recovery xxxxxxxxxxxx.img
reboot recovery
You should not need to remount, but if you need to or for future reference you type in adb remount from the command prompt and not in adb shell

Read an earlier post, download the file and do what the post instructs. You need the flash_image file on your phone

If you are in recovery and trying this you do not need to remount. If you are booted into Android try
Code:
adb shell
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
you might also replace /dev/block/mtdblock3 with /dev/mtd/mtd1
and then chmod

I am having this problem as well.

Okay if your having a problem with the ole "flash_image not found" saying do this open up command prompt and type
Code:
adb shell
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
then open up another command prompt with the old one still running and type this
Code:
adb push flash_image /bin
adb shell chmod 0755 /system/bin/flash_image
Now you should be good to flash your recovery

I'm getting all the same errors everyone else on here is getting. Is flash_recovery a file that is required? I don't mean the .img file, but is it some kind of command file?

Cannot flash a recovery image to a rooted hero. Please help.

I have tried every method I can find. The Flashrec, adb push, mount-a, flash_image recovery *.img
Flashrec says cannot run command
mount -a says something about no device
Flash_image says no such file or directory
Please help Im on 1.2.3
Thanks.

Not Dev. Mods please move to Q&A.

try this
adb push recovery-green.img /sdcard/
adb shell
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
cd /sdcard
flash_image recovery recovery-green.img
reboot recovery

Also, if you get stuck, search for ROM Manager in the market. it will let you flash the clockworkmod RA. After you have flashed that, you can look a little further down the list in that app, and you will see the option to flash RA Recovery v1.6.2. All of this is included in the free version of the app.

dude i was having the same problem for a while, make sure your phone is on and not in recovery mode, make sure its not mounted, just have it on charge only, and in the root of your sdcard and not in a folder, and make sure debug is on. also when i had the same problem i had a thread about it, just go through this thread and it will help you. in the mean time you can take your recovery image, rename it to something like myrecovery and that way its easier for you to remember it. then open up
adb shell, then type flash_image recovery myrecovery.img
heres the thread for me help. http://forum.xda-developers.com/showthread.php?t=685522

Thanks guys, Im gonna try these things now. I tried searching, but couldnt get my keywords right, my apologies for placing in the wrong thread.
Ill update soon with results.
Thanks again!

This worked perfect. I knew I was going wrong with the mount, it was basically telling me the syntax was wrong, and after pasting your command, I was able to flash the recovery perfect.
Thanks again. !!!! XDA ROCKS!!! DONATE!! I DO!!!!

I think you have to downgrade to a different version because i had the same message for flashrec and adb command.
The option I used was Clockwork Mod Recovery with Rom Manager. Just install Rom Manager and then click "Flash Clockwork Mod Recovery". With the recovery.img on the root of the sdcard.

I know you already figured it but just in case it does not work for anyone else this is an option.

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

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...
