Acer Iconia A1-B71 - Android Q&A, Help & Troubleshooting

Dear Users,
I have a tablet - Acer Iconia A1-B71, which works fine but I dont have root permission what is very annoying when I want to do something with Files Manager or Total Commander. I readed this thread:
http://forum.xda-developers.com/showthread.php?t=2240029
But for my bad I get errors. Below is a log file from CMD:
http://pastebin.com/EEiihY01
The most important part is this (I think):
Enter a selection:

If you can tell me - Am I doing something wrong? Is there any solution?

what your computer is trying to tell you is that it can not find the file "asroot2". make sure it is in the same directory where you try to execute the command, or give it an absolute path like this:
C:\AndroidSDK\tools>adb push c:\whatever\asroot2 /data/local/

it helps if i do this
1. Download the following file and then unzip
it.
AsRoot2
2. Take the unzipped file and save it into the Tools folder of your AndroidSDK.

[Q] How to root tablet based on Marvell PXA986 - Goclever Elipso 71

Got a tablet (most likely u wont recognize the brand - Goclever) based on a Marvel PXA986 - same CPU as Galaxy Tab 3 7.0.
Android 4.2.2
Any ideas how to root it?
I did it!
Few hours of research + some unsuccessful tries.
Thing that worked:
http://negativo17.org/root-the-zopo-zp980-c2-android-phone-using-adb/
Although pwn script returned an error, I am rooted now.
komoornik can you write how exactly you have rooted?
I also get pwn script error and then only errors no root.

[Q] chown with adb/root access: operation not permitted

On Note II rooted and fresh install of Cyanogenmod 10.3:
I want to do a symlink to save from cameras to externalsd. So I did:
1) CW recovery mode and adb shell. Command id reveals uid=0(root) gid=0(root) so I absolutely must have root access.
And then:
Code:
mv /sdcard/DCIM /sdcard/DCIM2
mkdir /external_sd/DCIM
ln -s /external_sd/DCIM /sdcard/DCIM
the /external_sd/DCIM folder has root:root ownership with full access (drwxrwxrwx)
Still;
Code:
chown media_rw:media_rw /external_sd/DCIM
results in "Operation not permitted"
I've made sure /system is mounted and I've tried the above after doing su for root mode (which I'm already in!)

[Q]Ihelp, I can't root my HDX 8.9, /system/bin/sh: chmod: not found

I have rooted my hdx8.9, and then I reroot it. Now I have some problem, I want to root my hdx again, but Ican't root it again, I have pushed the 4 files, but it didn't continue. It shows

What can I do, I want to full restore to stock rom to fix some proble as the post 'http://forum.xda-developers.com/showthread.php?t=2582773' says, but it
need your device rooted first.
Thanks.
Show us the script body you're pushing.
If you're using some ready scripts I assume the name of it is superuser.sh

I use the tool from the post “[ROOT] Rooting tutorial - hdx 8.9" 14.3.1.0” http://http://forum.xda-developers.com/showthread.php?t=2545957
@sdcardsd, Did you tried to use expression '/system/bin/toolbox chmod' instead of '/system/bin/chmod' in rootme.sh? For me it seems that you've lost the symlink. This may be caused by some busybox installation and removal.

I don't know whether I use these expression '/system/bin/toolbox chmod' instead of '/system/bin/chmod' in rootme.sh, I only use the tools to root my kindle. But I really installed busybox and then removal it by recovery to the factory reset after I reroot my device. Then I have some problem on my kindle, I think the system files be destoryed, so I want to full restore the original ROM, but I can't root my device again. And if it is caused by losing the symlink, how to fix it ? Thanks.
@sdcardsd, then make a suggested replace

The only way is to replace my device? But it is very inconvenient for me, I'am not in America.

@sdcardsd, just replace '/system/bin/chmod' by '/system/bin/toolbox chmod' in 'rootme.sh' file.

Hummmm. I'm looking into this but can't this week I'm super busy. I don't have the 8.9" I have the 7" so it is hard for me to test. I'm not sure if moving the rootme.sh was a good idea. I think the exploit code isn't finding it. You may need a rebuild of the exploit file. I say throw your question in here to see if someone can help. Still, just hope for the best.

this root exploit doesn't auto-install superuser (well it didn't for me), you either have to side-load it or get it through a store. Also if root explorer isn't working have you tried es file explorer? Additionally, you'll have to remount the system folder as rw before you can edit any system files. This can be done through adb shell with the command "mount -o rw,remount /system" after you use the su command. Just as a forewarning, be super careful when editing everything, the kindle is super sensitive to build.prop changes. I boot looped early on, so just as a warning.

Shell Script error

I am trying to make a simple shell script and I am getting constant errors.
So i made a test.sh file and saved it in /data because /sdcard is excuetable protected.
The shell file contains:
#!/system/bin/sh
cd /sdcard
mkdir test
su -c "rm /data/test.sh"
echo Done!
So then I typed the command chmod 777 /data/test.sh
I also tried chown root:shell /data/test.sh
And then /data/test.sh and it returned: tmp-mksh: /data/test.sh: No such file or directory
So then I tried running: sh /data/test.sh and it returned:
No such file or directoryrd
Done
I even tried executing the script from a root shell interface but still no luck same result as above.
Forgot to mention I am running 4.4.4 on a moto g that is rooted and has busybox installed.
