exec 'system/bin/sh' failed no such file or directory (2)

Hello,
I'm very new at this rooting stuff and I saw a lot of benefits from it so I thought I'd give it a try.
I've followed this root guide on MoDaCo, but I can't post a link here.
I also did the custom recovery image part (although I don't know what it is used for)
And I didn't make a goldcar either because someone told me I didn't have to do that as I don't have a carrier.
But my problem is I can't change anything as cmd keeps giving this error when I enter adb shell:
- exec ' system bin sh' failed no such file or directory (2)
I'm in my phone recovery and my usb cable is plugged in. This is the what I do and what it says:
C:\androidsdk\tools>adb shell mount /system
- exec ' system bin sh' failed no such file or directory (2) -
C:\androidsdk\tools>adb pull /system/usr/keylayout/bravo-keypad.kl c:\
remote object '/system/usr/keylayout/bravo-keypad.kl' does not exist
Any help is very welcomed as I've been searching the net for quite a while.

I'm not 100% sure what you are trying to achieve here. Are you trying to root, or have you already rooted?

Sorry for being unclear. I've already rooted.

OK, and are you looking to remap the hardware keys?
As far as the goldcard goes, you don't need it if you rooted without one.

Yes that is correct, but when I enter adb shell it gives the error given above.
I don't think it's supposed to give that error.

Take a look HERE it might be of help.

Yes, that's the post I used to try it.
But it seems I can't pull the file. It says the file doesnt exist.

I'm not really up to speed with adb commands etc. I'd maybe try posting this in the dev section. Or chuck a post in there pointing to this one.
Sorry I can't help you more.

Ok, will do, thanks for the help!

I think I've found my problem. I've installed the app: rom manager and I can get into the custom recovery from there.
It seems I was uncapable of going in the custom recovery myself (probably because I'm doing something wrong). But I'd still like to know what I did wrong.

If you've got rom manager installed, flash into clockwork recovery and go to the partitions menu and mount system then re-do you adb commands.
There's also a fake-flash that provides an update.zip to boot you in recovery mode.

Yes I've installed that fake flash, but I thought after installing it in the normal recovery it would take me directly to the custom recovery. Instead it just said the installation is complete without going to the custom recovery.

Everytime I want recovery mode I just load up rom manager and click reboot into recovery. However I find I can't mount my system directory through advanced cmd itself so have to mount through the partitions menu in clockwork.
Sorry of this doesn't help, I don't fully understand the issue..

Remove files from system

I'm trying to remove some preinstalled apps from /system/app folder. My phone is rooted.
When I'm trying this over adb it says that I only have Read permissions. What am I doing wrong?

Put the phone into recovery mode then do the adb commands.
You only have read access while booted. R/W access while in recovery.

Mh I tried this but I couldn't even open the shell, said something.sh is missing.
You mean the normal recovery and not Clockworkmod or something, right?

You have to put it in the custom recovery. Clockworkmod or whichever one you use.

Ah okay, thank you, I will try that.
Though I need to use the normal recovery.

I tried it with clockwork now. It works but when I do "cd system" and do "ls" it's empty...so I can't see any app-folder?!
Edit: Oh I forgot - do I need to mount system first using the partitions menu?!

Code:
mount /system
At the adb shell.

Oy, thanks now I finally got it
Remove worked, pull didn't (or it took >5min for a simple apk file and I aborted it too early).

[Q] Accidentally modified Framework

Like a dummy I tried to rename framework-res while using my nexus so I could replace it with an edited one (deb rooted, stock 4.4.4 rom, franco -17 kernel)
Now Im trying to ADB in to rename the original file so it will boot again.
I'm connected to the nexus in ADB but when I try to pull or rename the file I always get some sort of error.
I was able to adb push a framwork file I downloaded on my computer but it still wouldnt boot. Im assuming it was bad.
Any help is much appreciated!
thanks!

The reason it would not boot with the one you pushed to the device is probably because you have to set permissions correctly after the push. Framework res should probably be set to rw-r--r--
Run this after the push, or if the file is still on the phone, run it now.
Code:
adb shell
su
chmod 644 /system/framework/framework-res.apk

I will give it a shot the second I get home! Thank you so much for the help. So by default files pushed to the system do not have full read and write permissions?
Thanks again!

Yes, most of the time, pushed files will copy with bad permissions. Every time I've ever edited a system APK, I've had to subsequently set permissions before it would act correctly. Might not be 100% your issue, but it's definitely worth a shot.

Well now Ive run into a new problem. When I SU to get root access it tells me that /sbin/sh isnt found.
I rooted the n7 with cf autoroot.
this would be a whole lot easier if twrp would mount the tablet so I could just upload and flash a zip to update it.

Well I was able to sideload the boot animation herehttp://forum.xda-developers.com/showthread.php?t=2591471 just to confirm that sideload was working. I rebooted and it worked but still will not get past the boot animation.
The framework file simply needs to be put in /system right? so the command would look like
abd sideload framework-res.apk /system
Is that right?

You need to fix the framework file before you can boot. Try running the permission command without su first.

[Q] Were can I get original Stock Firmware for H815?

as file for download?
Thank you.
Best regards.

I've managed to kill mine worse than that, I cant get it to boot now after installing xposed framework 64bit, I can still get into TWRP recovery... Can't believe I didn't do a nandroid before I really started to play around. Oh well I'll live and learn!
I've gone through the steps to remove the xposed files but still having the same issues.
had to mount system with adb shell
mount /system/ to do the manual file deletions and renames

Same reason.
Nandroid will not help you.
I've made a Nandroid-Backup, but restore fails.
Please tell, if you have a solution.

Just wondering if your nandroid restore is failing because system is not mounted RW, have you tried mounting it whilst connected to a pc and issuing the following
adb shell
mount /system/
system should be now mounted rw in TWRP as well

What have I exactly to write, please?

Mine is also dead, but Recovery is still there.

My battery is empty
Loading this is difficult, while the phone is on and can not get off.
Always after connecting the phone reboots and is very hot, so charging is very slowly.

Find someone who hasn't yet flashed xpos ed and ask them to pull the system partition. Then have them upload it so you can download and flash via fastboot

If I had one I would.. Post something in the h815 boot loader unlock thread and ask them to pull their system. It would be beneficial to everyone who has a h815 until the kdz comes out

[TWRP][BL LOCKED][TEST][RootNeed] Twrp for Lg g4 with the BL locked, untested

I whipped up something quick based of stuff I used to do with the Droid X and what the Sony SP guys did.
This is twrp with a locked bootloader, the recovery partition is untouched, you can still get into that recovery. When the phone is booting, a green light will come on, hit volume up and then phone should vibrate within 3 seconds. If you hit the volume up then it should start loading twrp, otherwise it should continue with booting.
This is untested and I have a feeling the system will either not boot recovery, or not boot the main system.
This needs root.
This installs busybox, i know i should be using toybox
Someone please test, just extract the zip to your computer, plug in your phone, and run the appropriate file.
Do not test, I've tested it and I need to make changes
Sorry I was busy creating a new root method, got it working, almost done

Yup, in the future I might be able to make a marshmallow zip that'll let you run marshmallow with root and twrp. For that I need to relook into kernel modules because the kernel would have to be reloaded.

Yeah this opens the avenue for custom roms too, and multiboot and tons of stuff. Also, do not flash this if you are encrypted.

Hopefully this will allow for us to write the drivers that would allow us to unlock the band's that are locked. If this allows us to write drivers.

So, just extract and run install.bat? On normal mtp mount?

does it work with (vs986) version model

I'm interested to see if this works for the Canadian model (H812). Will keep watching this thread so good luck!

So the hope here is that we could downgrade to L, root, and then run this to get TWRP and install custom roms all without touching the recovery partition?
Has anyone had a chance to test this? I have a VS986 but it's the only phone I have with me right now so I'm hesitant to try myself

I ran this with a Verizon G4 and it doesn't appear to work. I don't get a green light when I boot up nor does pressing the Vol Up button at any point during boot up appear to have any affect. Perhaps I'm missing something in order to get into TWRP but from what I can tell it does not work.
