ABout to root, a question though. - G1 Q&A, Help & Troubleshooting

Hello all, I am about to plunge into rooting my G1. I have a question however. I found the guide http://forum.xda-developers.com/showthread.php?t=442480 and it lists the commands in telnet as:
* mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
* cd sdcard
* flash_image recovery recovery.img
* cat recovery.img > /system/recovery.img
I also found a video that someone had recommended at http://www.youtube.com/watch?v=xOo2V9qCauc
and it lists the telnet commands as:
Telnet Commands id
(Press enter)
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
(Press enter)
dd if=/system/bin/sh of=/system/bin/su
(Press enter)
chmod 4755 /system/bin/su
(Pres enter)
He then has you download and go into terminal emulator and then use these commands:
cd /system
(enter)
cat /sdcard/recovery.img > recovery.img
(enter)
flash_image recovery recovery.img
(enter)
The tutorial here is shorter and easier, but the people who tried that video have has success. Which is correct? Thanks all!

follow the guide you found here .. used it a year ago for mines and numerous times for others and it never fails
and also, thank you so so much for posting in the correct forum ... you don't know how many people will post in the dev section and use the "i'm a noob" excuse lol
and lastly, when you get to this part: "What To Do Now That You Have Root" .. you don't have to install one of those roms .. you can go over to dev section and install one of those ... I'd recommend the CyanogenMod roms ... you could also try out a Hero, Pulse, or Blur rom but they will require a lot more prerequisites than the CM rom

Thanks much for your input.

If you compare both you can see that the image flashing commands are the same, the second method just chmods a couple of directories (which isn't essential), so you can use either.

Thank you AdrianK.

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.

Add root to ROM

Hello,
I have created a ROM, but it does not have root access - how do I add root access to this ROM?
Thanks,
Isaac
From what I remember you need to go to Terminal, and type in:
Code:
telnetd
After that...
# Download an Android "Telnet" application from the Market and connect to localhost.
# If you connect successfully, you will have a root prompt "#".
# 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

That's only for RC29 though, and in RC29 it executed anything you typed in, so you are supposed to type it into the home screen. More info here:
http://forum.xda-developers.com/showthread.php?t=442480
Hopefully it will work on the ROM you worked on as well.
Good luck!
Big fan of your app, btw.
i want a SiriusXM player, and got mad you didn't have one,

Boot into the recovery console (power + home) and then drop into the shell (alt+x).
Then do this:
Code:
# mount system
# cd /system/bin
# cat sh > su
# chmod 4755 su
# reboot
Thanks! That worked perfectly!

Also how to add removed apps from DC 2.0.72 rom step by step please.

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?

[Q] Permission denied while pushing flash_image :(

Hi guys,
I just got a problem while flashing a recovery. I tried to use RomManager to flash the clockworkmod on my click, but while booting into it I just can enter the normal android recovery
I've read a little about this problem and found out, that I need to push the flash_image command line into the /system/bin - and there is the problem!
There're 2 different problems ... first one is permission denied - but I am root ...
Does someone has an idea why I can't push the flash_image?
Also tried http://forum.xda-developers.com/showpost.php?p=9192029&postcount=21 but it won't work - even with mounting the folders ...
Hope you can help me
Regards,
Smoky
Re

# chmod 755 /system/bin/flash_image
# cd /system/bin
# ./flash_image recovery /sdcard/recovery.img
# mount -o remount,ro -t yaffs2 /system
