[Q] adb shell "exec '/system/bin/sh' failed: No such file or directory (2)"

Hey,
Ok so a little backstory before my problem: So I was in the middle of putting a new ROM on my captivate. I had one before but i wanted to change so I put the rom in update.zip and installed it will clockworkmod recovery. It installed fine I think but then when I tried to boot it gets stuck on the boot screen. So i tried to boot in recovery mode. I geld down both the volume buttons and the power button until it reboots twice, then I let go of the power button. but it still gets stuck on the boot screen and does not go into recovery mode. So i plugged it into my computer and using
Code:
adb devices
it shows up under recovery mode. So far so good. I can use the
Code:
adb reboot
and
Code:
adb push
commands fine. but when i try to use
Code:
adb shell
it says
Code:
exec '/system/bin/sh' failed: No such file or directory (2)
So i can not reflash the recovery image. I read that I just needed to mount the /system file. But i do not know how to do this. the "mount" command does not work with adb. I would appreciate anything to help me to either reflash the rom or restore to factory or anything where i can work off of. thanks

I have exactly the same problem.
Did you get to a solution to this?
Good luck, dude.

Is there a solution to this without using a Motorola Factory cable? I don't have the resources to make one and I don't have money to buy one.

I'm not sure putting the rom into "update.zip" was the right choice.
adb shell could fail because the partition is not mounted, the sh binary is not installed, or not at the correct location
If you can still get the captivate into download mode, you could use odin/heimdall to flash a working ROM.

First of all...thanks to everyone that has EVER posted in the XDA forums! I've spent days reading them and I came across one that had a suggested solution for my problem. So let's start...
1) Bricked
2) ADB is finally working again...so..not a problem any longer
(Don't ask me how I got it to work again....I have no idea. System was wiped while using TWRP from a bootloop)
3) Now...with system wiped I have no '/system/bin/sh'
4)adb shell will not work because of this. adb root does not work because of production model. adb remount is not permitted.
Now....I came across a thread that suggest using r2.6.2.kindlefire.boot.insecure.img and zergRush. I have the zergRush file, but I need the r2.6.2.kindlefire.boot.insecure.img to push with adb.
Does anyone know where I can get the r2.6.2 at? Filesonic is disabled and Multiupload will not return page.
Link I came across: addictivetips /mobile/gain-root-adb-access-with-insecure-boot-image-for-kindle-fire/

help! phone is busted

my phone seems to be in a really weird state right now - turning it on does absolutely nothing but adb does in fact detect it.
Code:
List of devices attached
HTXXX device
and if i run 'adb reboot recovery' i see the device in recovery mode.
Code:
$ adb reboot recovery
$ adb devices
List of devices attached
HTXXX recovery
also, while in recovery i can do adb shell and attempt to do a nandroid backup, but i get:
Code:
$ adb shell
~ # nandroid backup
E:unknown volume for path [/sdcard]
Can't mount /sdcard
at this point i've called htc to send it in for repair, but i would really like to get a backup before that and also return it to S-ON. i was running the latest clockworkmod and android revolution.
any help would really be appreciated.

Have you tried flashing an RUU?

yes, it keeps failing when trying to reboot into the bootloader. i've given up at this point - will be sending it back to htc and just hope they don't charge me some ridiculous amount just because i have s-off through the revolutionary script.

Is by any chance you phone connected as disk-drive? Try connecting it as charge only.

well the problem is the screen doesn't turn on so i can't see what's going on. although i'm pretty sure it's not connected as a disk drive because it doesn't automatically enable that.

Recovery Problem.

I have problem with CWM v5.8.3.4, while i flash, restore, back, everything it still back to recovery mode, can`t do nothing.

CWM v5.8.3.4 -- Here is your problem, you used ROM manager to update recovery. There are red flags on this pretty much everywhere Dx
You've gotten into the bootloop, see my PERI tool (Link in sig) and try and run the bootloop-fix there, if you can get adb working. You can also try it manually (Again, adb permitting) in roach2010's recovery touch thread, he provides the fix there.
If you can't get adb working at all, you need to NvFlash back to stock, wheelie thread is again in my signature.
Good luck.

By the way, you can get back into Android by Cold-booting the system. Hold volume-down, then press power and keep holding volume-down till it boots. Don't press volume-up or anything else, that'll put you back into recovery.

I was tryin` but while i want to flash someting apx turning off and can`t do nothing :/ Erm, how to fix can`t use my tablet about 1 month

Hi,
have you tried coldbooting ?
Hold power and volume down. Should get you out of recovery.

Yes, i do mate, and can`t do nothing. It dont see sd card and tablet memory :/

Okay I have the same problem, i used the cursed Rom Manager and now im stuck in the endless boot cycle, I can cold boot and I have tried to flash roachs cwm but nothing. Ive read where roach gives a code that might fix it, but i have no ideal what to do with that code or how to use it, and i see where thing o doom said the fix is in his signature but im not having much luck with that either. If you could maybe explain to me how im supposed to use roaches code or post the link that explains it here, I would sure appreciate it. Thank you.

Any ideas please? :/

Start an adb shell session with your computer connected, or in a terminal app on your tf, then run roaches fix (type it in) to the terminal app/adb shell session.

"then run roaches fix" u mean write app/adb shell session ?
And now i got another problem:
"E: Can`t mount /sdcard/
Biggest problem for now, i can`t turn on debuging :/

okay I opened terminal emulator on my tablet and typed in roaches fix exactly like it says
adb shell dd if=/dev/block/mmcblk0p3
and this popped up
*daemon not running. starting it now on port 5038*
*daemon started successfully*
error: device not found
255 [email protected]:/ $
what am i doing wrong? thank you so much for your continued help
Ive also tryed the peri and easy recovery with no luck, I think my bigest problem is i dont understand the adb thing, ive tryed searching about it and im lost.

That's the wrong dd command, dd consists of an if=/ then an of=/
Try this.
adb kill-server
adb start-server
adb devices
(you should see the tf, if not, bad drivers/not working connection, fix that first)
adb shell
su (Grant superuser permissions, if you can, and you'll see a # sign)
dd if=/dev/zero of=/dev/block/mmcblk0p3
reboot
Then flash a new recovery by:
Download and extract recoveryblob from recovery.zip
adb kill-server
adb start-server
adb devices
adb push C:\path\to\recoveryblob /sdcard/
adb shell
su (you'll get # sign again)
dd if=/sdcard/recoveryblob of=/dev/block/mmcblk0p4
reboot

I have to thank you for your patience and continued help with my problem, but with that being said I must inform you that I am still completely lost. Im not a developer and I would not even consider myself remotely knowledgeable in the subject. I was just wanting a nice custom ROM and I had found one with cyanogen mod 9 but I messed up by using the Rom manager and now I'm screwed.
I can cold boot into my tablet, and on my tablet I have this computer emulator program, which i can type in the codes you mentioned, but I'm pretty sure that is not correct. what i need is a program like that on my computer, so far I found this link regarding adb, but I'm not sure if it is right direction.....
http://theunlockr.com/2009/10/06/how-to-set-up-adb-usb-drivers-for-android-devices/
if this is the wrong direction, can you please point me in the right direction? again I am sorry for my ignorance and when this is all done I will be sure to buy you a freaking case of beer. Thank you

You can run the adb commands on your TF using the emulator app, but you'll need to directly download the recoveryblob used to flash.
Open terminal and run roach's fix (except instead of typing adb shell, you just start from su, then run the dd command from there, since you're already in the tf's 'shell')
so
su
dd if of etc
reboot
Then you'll need to reflash a recovery, so download Team Rouge's Recovery.zip then use ES file explorer app (download that) to extract the file called 'recoveryblob'. Take that file called 'recoveryblob' then copy it out of the downloads folder (still using ES file explorer) hit the favorites button then hit /sdcard/ (You don't need a microSD card to do this, /sdcard/ [For whatever reason ..] is the Internal storage. [/removable/microSD/ is the external]) then paste the recoveryblob right in /sdcard/.
Open up the terminal emulator and run
su
dd if=/sdcard/recoveryblob/ of=/dev/block/mmcblk0p4
reboot
That should give you recovery! (Then you can reflash a ROM or do whatever you need/Enjoy not having to cold-boot everytime)

Im stuck w8ing for You at Skype: )

Thanks for your info. TF now up and running without the need to cold boot. For information, I did not use a Rom Manager to flash the rom, I used CWM to flash the Gummy Rom.

I finally got my tf101 fixed and I learned something new. I just wanted to thank Thing of Doom for all of the help he offered me and without ever asking anything in return. Thanks.....

If anyone wants to know, here's what I did to fix nefem's completely FOUBAR TF101g.
First I tried NvFlash, then right at the flashing stage realized it's a tf101g Sbkv3, so that was out X.x
Then I uninstalled all the drivers and reinstalled them with PERI, got ADB working through recovery.
I had him try and flash a .zip file for a new recovery so I could run Roach's fix, but for whatever reason the CWM wouldn't mount the Internal storage (mmcblk0p7 or /sdcard/) so I manually pushed the recoveryblob to /sdcard/ and it seemed to work, but when I ran dd if=/sdcard/recoveryblob of=/dev/block/mmcblk0p4 it couldn't mount and find it.
The next thing I tried since internal was acting funky was looking at the log, I noticed that the directory was /system/sbin so I just pushed the recovery to there, adb push recoveryblob /system/sbin, then ran the same dd command with that directory and it worked. Then I just ran roach's fix normally and rebooted, he had rouge recovery!
That was the first part, his internal was still borked for some reason and Rouge couldn't mount it.
I tried various ADB mounts and they all failed, so eventually he put a MicroSD into his phone (or something else) I placed the ARHD superswipe script and a ROM w/ Guevor's kernel on there, then since rouge reads external, superwipe was able to completely format internal storage. From there it was an easy wipe and flash. Once we got a working ROM on there, we noticed that it was still getting stuck at the Eee pad logo (He could cold-boot). So I figured that his bootloader was still messed up, so we took the latest Tf101G stock blob, used the handy Rayman's blob tools to pull out the EBT (bootloader partition) blob, then directly flashed that with dd again through adb: dd if=/sdcard/blob (Removed the EBT extension, important) of=/dev/block/mmcblk0p4
Reboot, and finally it was booting optimally!
It was a tad of trial and error (The internal storage thing really had me confuzzled) but it all got fixed up in the end.
Hope this helps someone somewhere

I am having the same exact problem as him with the same amount of programming expertise....I was woundering if you could walk me through it personally as what you've typed above seems like it's in a different language. Thanks very much in advance.

Screen not working

My wife's screen has stopped working. She says it may have gotten wet from sweat while she was on a walk this morning, but I'm beginning to suspect it's been dropped because one side of the removable cover isn't very secure. Anyways, the screen briefly flashes bright white when the screen is turned on. I can tell the phone is still operating normally because of the sounds and vibrations it makes (e.g. start up sound, notifications, phone calls, etc...). Is there anything I can do short of sending it to HTC for repair? If I do send it, does it need to be returned to stock? How would I even accomplish that without the screen working?
Thanks

HTC in the past have been pretty good at warranty work even when device is rooted/bootloader unlock.
You could try to relock the bootloader and run tmobile ruu.
with the power off you can hold Vol down and power button to get into hboot.
I don't have the phone in front of me but iirc that should put you in fastboot already, if not you might need to hit power button once to
get into it. Run the fastboot command to lock bootloader.
Code:
fastboot oem lock
When done it should reboot, get back into bootloader, fastboot and run tmobile RUU

Thanks for the information.
Is there any way to force USB mounting from adb? I need to pull some stuff off of the internal SD.

Apparently I turned off USB debugging on this phone, so I have no way to connect to it. Do I have any options other than shipping it off to HTC?

If you still have fastboot, you can fastboot boot into a recovery, then get an adb shell. From the shell you can mount your sdcard, and look around on it to find what you want to pull. You can use adb pull to pull entire directory trees, not just single files.

I'm able to connect adb in fastboot, but mounting /sdcard fails.
Code:
~ # mount /sdcard
mount /sdcard
mount: mounting /dev/block/mmcblk0p36 on /sdcard failed: Invalid argument

Ayyy .. well I don't really know then..
You can try and get your sdcard mountable by flashing and booting a stock recovery, and then fastboot booting a custom recovery. May be snake oil tho.
Do some searching on how to fix unmountable /sdcard
If youre on linux, you could try this:
Code:
( adb shell cat /dev/block/mmcblk0p36 ) > sdcard.img
If it starts writing a growing file on the host, wait for it to finish (will take ) and then
Code:
mount -o loop -t vfat sdcard.img some/mount/point
Unfortunately I have no guaranteed recipe..

Is there a way to delete/uninstall an APK and its data from fastboot?

so i went into FKU franco kernel updater and changed my CPU max speed from 1500 back to the default but did not change my voltage settings back to default. now the device is softbrocked and just boots to the google nexus splash screen
I have tried flashing:
system.img
boot.img
bootloader.img
stock 4.4.4 kernel
yet regardless of flashing the above the device still is softbricked and wont get past the nexus google logo.
the only thing i have not flashed over is my user data and thats because i dont want to lose my pictures and video of my little boy that i didn't get to back up yet due to my dropbox just hitting its limit.
Im hoping I can remove the franco updater app and its user data and boot but maybe thats not possible?
Thanks for any and all help!

Do you have a custom recovery? If so, use adb while in recovery to pull your files. If not, then flash one then pull them.
Not sure why you mentioned "boot.img" then "stock 4.4.4 kernel", boot.img = the kernel lol
Don't know why your device won't boot even after flashing stock boot.img, but if you use TWRP you can use the file manager to delete the .apk/other files.

thanks, i deleted the franco files and still cant boot.
i want top pull files but it looks like I need ADB and currently i can only get into fastboot mode.
(i'm using wugfresh toolkit, i know some say manual is the way to go but right now this is what I have to go on and have had no issues thus far with it)
i was using the button pull files in the tool kit but its not detecting the device since im in fastboot mode.
i swear I did a factory reset before and my photos were still present but many articles online say in 4.4 that a factory reset will wipe your photos.

since i can not boot, i am forced to use TWRP recovery and then go ingo CMD shell and ADB there however when I do ADB Devices i get the serial number showing its connected but then it says RECOVERY at the end.. much lke when you are in fastboot it says FASTBOOT at the end of the device.
i tried doing a pull using this:
adb shell
mount data
exit
adb pull data/media/0 c:\MyBackup
but when I do ADB Shell, the command prompt says this
~ # ←[6n
if t that prompt i type mount data then I get this:

im not sure how else to get to a working ADB to perform a proper pull if i cant boot into the device fully

It could say "device busy" if data is already mounted. Does twrp have a "mounts and storage" menu like CWM? Where you can mount data? If so, check if it is mounted there (would typicall say "unmount data" if it was mounted, otherwise it would say "mount data" if it is unbmounted)

ok so i went into TWRP and UNMOUNTED DATA
and then I went back in to cmd prompt and tried mount again and it worked i guess since theres no error. I typed EXIT and was brought back to normal windows command prompt. I then typed
adb pull data/media/0 C:\Users\srobertson\Desktop\Nexus 5 7-15-2014 DCIM
and when I hit enter it just shows a list of ADB commands as if it didnt recognize anything yet when I do ADB DEVICES it shows the device and ID

If you're going to put spaces in your folder names, you'll have to enclose the entire path in "...
Example
adb pull data/media/0 "C:\Users\srobertson\Desktop\Nexus 5 7-15-2014 DCIM"
Best to avoid spaces though.
I'll put this in the guide, thanks.

I ended up taking the leap and performing a Factory reset from TWRP and when I logged back into the phone I saw all my media was still present Whew.
just for posterity I went ahead and tried your code in ADB to make sure the quotes worked and it did so thank you very much and i will keep those notes handy for next time.
