comment How to remove a system file using adb shell?
Have you checked whether /mnt/extsd is writable (ls -l /mnt |grep extsd)? If it is not, you can neither chmod nor rm its direct contents.

You might wish to check Can not unlock my Android device as have no internet connection? for how to work around that "too many pattern attempts" issue. No risks for you, as there's none of your personal data to lose :) Having accomplished that, boot it up completely, and go to Settings→About Tablet for more detailed information. If you cannot figure out yourself from that, posting a screenshot might help us helping you.

So what is stopping you? Where's the problem? Maybe you edit your question and add some more details?

comment Acer DA241HL - system reset from bootloader
If they are all the same devices, it should be possible to "dump" the partitions of one device and "flash" them to the others, essentially "cloning" the entire system. But that requires root. You could use either a custom recovery and Nandroid (check our nandroid tag-wiki for details), or utilize dd for it. I never did that myself, and partition names are quite device specific, so I cannot give detailed help on that.

comment Acer DA241HL - system reset from bootloader
No "reset" will ever roll back any system updates applied. For that, you would have to re-flash the original ROM. For the device to show up with adb devices or fastboot devices, you must have your computer configured accordingly (Windows needs special drivers, Linux/Mac might be happy with just some configuration settings – see e.g. our adb tag-wiki).

comment How to get “Non-Root” access on Emulators ?
You could try su shell to become the "shell user". That's the one adb shell normally uses on devices. But I'm not sure if it is available on the emulator, so please let us know if it works. If the shell user is not available, you could check ls -l /data/data to pick the user of some app to try with.

comment how to run binary on non-rooted android phone?
My bad, /data/local is owned by system:system, and not world-readable. But unless a similar permission issue exists there as well, ls /data/local/hello should work. If it does, please also cross-check with id to see whether the user matches.

comment Is it possible to Install cyanogenmod on Galaxy S2
Have you checked with the CyanogenMod Wiki? It has a dedicated area for the I9100. Depending on which version you want to install, you can check everything there. As this is subject to change with new versions, I won't re-type all the details here :)

comment No menu entry for mobile network mode after installing CyanogenMod
What do you mean by "mobile signal"? Are you talking about mobile data (in this case, you should check the "Access Point Names" menu, and probably will have to add an appropriate APN), or does it include the "phone signal" as well?

A good starting point is our insufficient-memory tag-wiki. Please check the first-aid provided there, then return and let us know whether your issue solved that way – or what you've tried and where you're stuck otherwise.
