Galaxy S III adb shell error - Galaxy S III Q&A, Help & Troubleshooting

I was looking up the partition layout of the Galaxy S III while I stumbled upon this problem.
The first time you run a command in 'adb shell' everything is fine, but when you try to run a second command, it just hangs. It doesn't crash, it just hangs.
So, I tried to find out what could be wrong, by doing the following: Instead of going into the shell itself, I just entered a semi-random command 'adb shell mount', which returned the normal result.
Then, I typed 'adb shell' and guess what? It returns a commonly known error: 'error: protocol fault (status 72 6f 6f 74?!)'
The status code is HEX, which translates to: 'error: protocol fault (status root?!)'
So I suppose this has something to do with the fact that my SGS3 is rooted.
I don't feel like unrooting it, but if someone would be so kind to test this on an unrooted SGS3 and report back the results here so we can investigate this further that would be greatly appreciated.

it works without any error.
do you know what to backup which contains kernel and ramdisk ?

Mine is rooted, with Omega Rom V3 and everything works perfect with adb.

Have you tried multiple shell commands? I know adb functions, but it's about using adb shell.
I'm on the stock rom, rooted manually with CF's insecure kernel by the way.

I'm not sure this is related, but there is some very suspicious new functionality in the FactoryTest.apk, called "SysScope". Its some kind of service checking and verifying the authenticity of "something". But I have no idea of what, only that a related java file (ResultCode.class [sysscope.service] contain the following code segment:
Code:
[SIZE=2] arrayOfResultCode[0] = OK;
arrayOfResultCode[1] = ADB_RUNNING_AS_ROOT;
arrayOfResultCode[2] = PARTITION_TAMPERED;
arrayOfResultCode[3] = ROOT_PROCESS_FOUND;
arrayOfResultCode[4] = DANGEROUS_FILE_DETECTED;
arrayOfResultCode[5] = NOT_OFFICIAL_BINARY;
[/SIZE]
Then it looks for SysScope files in the SysScopeVerifyer.class like this:
Code:
[SIZE=2]/data/app/com.sec.android.app.sysscope-1.apk
/data/app/com.sec.android.app.sysscope-2.apk[/SIZE]
I suggest you to back these up, and then replace them, with empty files of the same name, and see what happens.

I have the exact same problem on the GS2, OneX, and OneS. I have no problem shelling into the devices using another system, but on one of my computers I have the same issue. Windows 7 64bit with jdk7 installed.
Also, I enabled adb trace to see what was being returned: set ADB_TRACE=all
-Entering ls three times on the OneX, the first time works correctly
