[Q] Nexus S (rooted) does not save clockworkmod recovery after reboot - Nexus S Q&A, Help & Troubleshooting

Hi,
I have followed all of these steps theunlockr.com/2010/12/17/how-to-root-the-samsung-nexus-s/[/url] up to VI. Stop the Phone from Uninstalling the Custom Recovery Image. After I shutdown the phone I hold the volume up and press the power to go into fastboot however when I press recovery, the clockworkmod does not save and just boots the stock recovery. Once I type in adb shell
cd etc
mount -o rw,remount /dev/block/mtdblock3 /system
mv install-recovery.sh install-recovery-no.sh I get mount: Operation not permitted.
I hope someone can help me. Thanks to whoever is reading this.

the correct way to flash the recovery would be through fastboot. "flashing" it with rom manager doesnt cut it. do a search, theres lots of info here. good luck

I think he already flashed CWM with fastboot, and is now trying to rename install-recovery.sh
Just follow these steps:
1) Boot up your phone.
2) Use Root Explorer to browse to /system/etc
3) Press the "Mount R/W" button
4) Long press on install-recovery.sh
5) Rename it to "install-recovery.sh.bak"
6) Go back into bootloader
7) Use fastboot to flash ClockworkMod Recovery again like you did the first time.

Does adb have inherent su privs? Or is the problem that he did not request su privs?

adb does not have any inherent root privileges. You either need an insecure boot image for adb remount or you need to request su privileges and remount /system manually (or through an app like Root Explorer).

Question about rooting and flashing recovery image..

Just curious, what happens if I follow the rooting steps in the other thread but only do this:
adb push /directory_you_placed_asroot2/asroot2 /data/local/
adb shell
chmod 0755 /data/local/asroot2
/data/local/asroot2 /system/bin/sh
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
cd /system/bin
cat sh > su
chmod 4755 su
At this point, what state is the phone in? Do I have full root access to the file system? What are the issues/concerns if I don't proceed with flashing the recovery image. Just trying to understand the process and what each step is for. I understand the part above but can't understand why you have to flash a recovery image and can't just use the phone after root is achieved.
Thanks in advance. FYI...all I want to do with root access is delete some system files, nothing more.

You don't have to flash the recovery image. I believe from that code you would have root and can run programs that require root. However, you would be unable to flash a new rom or any other update.zip (which means no auto apps2sd), partition your sd card easily or backup your phone in case something goes wrong. I suppose you are probably just asking for the sake of asking and knowledge but this is why a recovery image is HIGHLY recommended.

thanks. So if I don't flash the recovery image, I can't update to cooked ROMs or do the stuff you suggested but will the phone otherwise function normal? i.e. I can update to a Sprint/HTC update, I can factory reset the phone (assuming that'll kill root), etc.? I may do the whole process with the recovery image later but don't need it right now.
I only need to do this as a stopgap until Sprint/HTC releases an update.

Well, I wouldnt recommend doing a sprint update either. That will cause you to lose root most likely. The only way then to keep root is wait until we get a dump of the update and then cook a rom that includes root, in which case you would need to flash the recovery image. Updates usually fix the exploits we use to gain root.

What he said...but yes, at the steps you quoted, mobilehavoc, you are capable of root access (you don't actually have it until you run that "su" command ). That allows you to read and modify otherwise locked away files and tweak to your hearts content!
Ive rooted and played around some but very little and followed everyones instructions very closely ( thank you for teaching a newbie ). Now how do I go back to original state that I backed up ( think I did ).
When I press the power and volume down button I get to the droid on skateboard, then I press the Home for recovery. I get the screen with all the options and I go to nandroid v2.2 restore and press trackball. It says restore latest backup press home to confirm. I do that and get the following error
Error : run 'nandroid-mobile.sh restore' via console.
What does this mean? Do i have to be tethered to PC and run this command from cmd prompt?
I am now lost again, any help is appreciated

Just to confirm since it wasn't mentioned, you did a Nandroid backup earlier right? can you confirm that there's a folder on your sdcard called "nandroid"?

You must do a backup BEFORE you can do a restore..
To clarify for everyone, here's a breakdown of the steps:
adb push /directory_you_placed_asroot2/asroot2 /data/local/
This copies the asroot2 program to the /data/local folder on your phone.
adb shell
This logs you into the phone. From here on out, you are no longer executing Windows commands from a DOS shell - you are actually executing Linux commands on the phone.
chmod 0755 /data/local/asroot2
This changes the permissions on the asroot2 program so that it can be executed.
/data/local/asroot2 /system/bin/sh
This actually runs the root exploit and creates a file called /system/bin/sh that we will later turn into su.
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
This unmounts the /system partition and remounts it as writeable.
cd /system/bin
This puts you into the /system/bin folder.
cat sh > su
This creates the su program.
chmod 4755 su
This changes the persmissions on the su file to allow it to be executed.

Can you provide those steps? Sorry but complete newbie here
"I get the screen with all the options and I go to nandroid v2.2 restore and press trackball. It says restore latest backup press home to confirm. I do that and get the following error"
Go there but select Backup instead of Restore.
Turn the phone off, hold the Home key, and turn it on. When you get to the screen with the green text select nandroid backup.

[GUIDE] How to Flash a ROM WITHOUT an SD Card

How to Flash a ROM Without an SD Card
​
This is for all those who don't have a working sdcard, sdcard slot, etc. but want still to flash a new rom
Prerequisites:
Flash an Amon_RA recovery if you're using Clockwork - I recommend Darch's unofficial (CDMA Hero refer to my signature if you need it)
Access to a computer that had AndroidSDK tools on it - you'll be using ADB
Put whichever ROM.zip you want to flash in your android-sdk\tools folder - I would rename it to something simple. (My example which I'll be using for this tut is: C:\AndroidSDK\toosl\ROM.zip)
Directions:
Reboot into the Amon_RA recovery
Wipe data/factory reset, cache, and dalvik via the recovery menu
Open up cmd/terminal on your computer
Navigate to your android-sdk\tools directory
Enter the following in cmd/terminal:
Code:
adb shell
mount data
*wait a second or two* You may or may not get the "/ #" line returned.
Despite what happens press "Ctrl+C" to break the command and get back to the standard AndroidSDK\tools> directory
Enter the following in cmd/terminal:
(replace "ROM.zip" with the name you're using)
Code:
adb push ./ROM.zip /data/
*this will take anywhere from 30sec to a min depending on the rom.zip size*
Then we do this in cmd:
Code:
adb shell
recovery --update_package=DATA:ROM.zip
Wait for it to finish flashing/updating
Reboot
ENJOY
Brief rundown of what we just did:
Wiped /data/ to free up space for the zip
Put our ROM.zip onto the /data/ partition since we don't have an SD Card to work with.
Told the recovery to flash from our /data/ partition instead of /sdcard/
I did some digging around the AmonRA github to look for the commands it actually performs while in recovery I figured out exactly how to do what I wanted.
(namely THIS PAGE for those of you who are interested in seeing the exact page I found them on)
Good knowledge man. Thanks for the guide

How do you flash the recovery without an SD card tho?
EDIT: I figured it out. I will post my steps later.
Here is what I did:
Rooted phone
Attempted to push Flash_image - failed due to filesystem permissions
Steps for Flash_Image:
adb shell
su
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system/bin
chmod 777 /system/bin
exit/ctrl+c
adb shell
adb push flash_image.zip /system/bin/flash_image
adb shell chmod 0755 /system/bin/flash_image
Flashing Recovery:
adb push Recovery.img /system/bin/
adb shell
flash_image recovery /system/bin/Recovery.img
rm /system/bin/Recovery.img
reboot recovery
Then proceeded to follow the steps in this guide successfully

tip: use 'adb remount' instead of the manual mount commands. Do that before you adb shell. Just saves a bit of typing.

EDIT: Forgot to mention that you rock! Thanks for the earlier help too.
EDIT 2: Nevermind, did some reading on what 'adb remount' does and found out it remounts /system with read+write access so I guess this is it. Though please do correct me if I am still wrong (which I am often).

Dunno, I don't have plans for using it ever again nor have I looked at Clockwork's github - if there is one.
But it should be able to if you can find out what scripts/commands are run when you use the menu. If you want to you can check the github link I have in the OP to see where I found the commands that are run, and then look for something similar in clockwork's source.
You'd be looking for something similar to:
Code:
--update_package=root:path - verify install an OTA package file
Thanks for the awesome guide! Saves me a lot of trouble, I don't have to take out my sdcard or manually enable USB in recovery anymore!

[Q] [i9020a] Nexus S - can't remove / rename install-recovery.sh

Hello,
I have a Nexus S which I am trying to root and flash CWM recovery on. I've followed "The Unlockr's Guide" which was a tremendous help as well as kursk's "Step by Step ROOT Nexus S via ClockworkMod Recovery image (i9023 and i9020A)".
I am having issues however, renaming / removing the "install-recovery.sh" script. I've tried to rename it using Android Mate. I get the error message "failed to rename to install-recovery-no.sh".
I've also tried to use ADB Shell by trying:
"mount -o rw,remount /dev/block/mtdblock3 /system" which go the following error:
mount: operation not permitted
so I couldn't perform the rename using the mv command.
I really don't know what else to try... Any help would be appreciated.
Thanks.
Just start from begin again and use this guide. I have also i9020a and I was done in 15 minutes, newer did it before with Nexus S. good lack

I just renamed it using root explorer. Worked fine for me
Thanks deeren,
That worked. It removed the recovery-install.sh script altogether. One question, if I ever want to go back to the stock recovery, is there a script I can use to bring it back?

If you are on stock rom, then you can just reflash any stock rom (without wiping , so that you do not loose your data) and it will put back the script back.
you could also pull the script from any stock rom and push it back to your phone using adb.
move along, empty post, nothing to see here
I think..just flash any Stock ROM..
and your Stock Recovery will be back...

[HTC EXPLORER] Flash back to Yannou90's recovery after flashing CWM

The official CWM has problems in mounting SD-EXT, thus, Jaggyrom and other custom roms (except stock) won't work properly and your phone will reboot everytime you install apps. You'll also get a lot of app crashes because Dalvik cache can't move properly. Now here's how to flash back to Yannou90's recovery using only Android Terminal Emulator.
__________
THINGS YOU NEED:
1. Your HTC Explorer must be rooted
2. Flash_image and Recovery (You can download it here on this thread)
3. Root File Explorers (Like Root Explorer and ES File Manager, at play store)
STEPS:
1. Download the zip file, read the readme inside the zip, and extract flash_image and recovery.img to the root of your SD Card
2. Download Root Explorer from play store, you can use ES file explorer if you want a root file explorer for free
3. Using your root explorer, copy flash_image to /system/bin/ but before you do that, make sure you mount /system/bin/ as R/W.
4. After copying flash_image, set flash_image permissions to rwxrwxrwx
5.Download Android Terminal Emulator on Play store
6. Run Terminal Emulator and open up preferences.
7. at the initial command, put this:
export PATH=/system/bin:$path
7. Go back to Terminal and Type su
8. Superuser should prompt. Accept it.
9. If you saw # it means you are running it as root, which is that we really needed. If you saw $ , it's not running as root and do type su again.
10. now type this:
flash_image recovery /sdcard/recovery.img
11. Wait for it and if it's done, boot your phone to recovery.
12. CONGRATULATIONS AND YOU ARE BACK TO YANNOU90's RECOVERY

Check superuser and make sure Terminal is allowed. And type su in all lowercase, not uppercase like SU. That wont work

The official CWM has problems in mounting SD-EXT, thus, Jaggyrom and other custom roms (except stock) won't work properly and your phone will reboot everytime you install apps. You'll also get a lot of app crashes because Dalvik cache can't move properly. Now here's how to flash back to Yannou90's recovery using only Android Terminal Emulator.
__________
THINGS YOU NEED:
1. Your HTC Explorer must be rooted
2. Flash_image and Recovery (You can download it here on this thread)
3. Root File Explorers (Like Root Explorer and ES File Manager, at play store)
STEPS:
1. Download the zip file, read the readme inside the zip, and extract flash_image and recovery.img to the root of your SD Card
2. Download Root Explorer from play store, you can use ES file explorer if you want a root file explorer for free
3. Using your root explorer, copy flash_image to /system/bin/ but before you do that, make sure you mount /system/bin/ as R/W.
4. After copying flash_image, download Android Terminal Emulator on Play store
5. Run Terminal Emulator and open up preferences.
6. at the initial command, put this:
export PATH=/system/bin:$path
7. Go back to Terminal and Type su
8. Superuser should prompt. Accept it.
9. If you saw # it means you are running it as root, which is that we really needed. If you saw $ , it's not running as root and do type su again.
10. now type this:
flash_image recovery /sdcard/recovery.img
...
After this step what I get is as follows
usage: flash_image partition file.img
sh-3.2#

Superuser worked fine on terminal. But also got permission denied on last command in terminal.. should I push it via ADB?
You can simply flash the recovery using fastboot. Download this ZIP: http://forum.xda-developers.com/attachment.php?attachmentid=913094&d=1329843100 (courtesy of jaggyjags), start your phone in fastboot mode (ROM Manager might be able to reboot your phone into this mode, otherwise just turn it off, pull out the battery and replace it, then turn on while holding volume down and choose "FASTBOOT" from the menu that appears), then run "recovery.bat" from inside the ZIP. It's simpler than having to mess with adding files to /system/bin.
FYI, you need to set permissions on flash_image to allow it to be executed. I think typing this in the terminal emulator should work:
Code:
chmod 777 /system/bin/flash_image
(otherwise use your file manager to change the permissions to give read, write and execute permissions to all users i.e. tick all the boxes). This is the missing step from your guide to make it work from terminal emulator.
Also, you don't need multiple apps, you can just use terminal emulator for it all by using the "cp" command e.g. if flash_image is on the root of your SD card, use the following commands:
Code:
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
cp /sdcard/flash_image /system/bin/flash_image
then use the chmod command above and then the original command from the first post.
[BTW, if you're wondering, the first command identifies as root, the second remounts /system as RW, the last copies the file]
So the full process for terminal emulator ONLY, would be this:
Code:
su
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
cp /sdcard/flash_image /system/bin/flash_image
chmod 777 /system/bin/flash_image
flash_image recovery /sdcard/recovery.img
{rm /sdcard/flash_image
rm /sdcard/recovery.img}
The commands in the {} are optional and just delete the two files from your SD card. The 2nd and 3rd commands can be excluded if you copy flash_image with a root capable file manager, as can the 4th if you change permissions with the file manager.
(This post ended up being much longer than I originally intended. I was just going to post the first paragraph, but figured I may as well post how to make it work the way the OP described as well - or at least what I think should make it work, I haven't actually tested the full process [I have tested the exact same process with other binaries {viewmem, tcpdump} and it works perfectly. Provided the usage of flash_image as in the OP is correct and works, this method will work])
EDIT: You also shouldn't have to change the initial command, /system/bin is already specified in $PATH. If it wasn't, pretty much nothing on the phone will work.

Thank You. U completed this thread. Decided to use fastboot (faster) instead of terminal emulator way.

And...
I used Android SDK tool, and used the below command in command prompt and then I reboot the mobile, and I got back:

Thanks for this valuable thread

hi! I have a question regarding recoveries... i have a recovery by yannou90 installed on my htc explorer, will this recovery work for other roms such as CM9 and CM10? It worked well with JaggyJags rom (3.2.1).. i am wondering if I need to switch to other recovery prior to installing CM roms.. thanks!

My initial response to such a situation would be start the phone in fastboot mode and then flash the recovery from there. Download the ZIP here: http://forum.xda-developers.com/attachment.php?attachmentid=913094&d=1329843100, extract it and double click "recovery.bat" once the phone is in fastboot mode (start phone holding volume down, select fastboot from menu instead of recovery).
This assumes you're on Windows. If you're on Mac/Linux, find the fastboot binary for your platform and run the following command in a terminal:
Code:
./fastboot flash recovery recovery.img
where recovery.img is taken from the ZIP I linked above.
Alternatively, you could install a more up-to-date recovery such as TWRP or a newer build of CWM (not sure of links for the latest versions of either, but have a look around the forum and you should find them. Also some older builds of CWM had bugs [hence this thread exists], but I think the newer builds work fine on the Explorer; not 100% sure as I still use yannou90's build)
