Don’t know whether the app is still available or not but yes the steps to do the same are.

    Hi Atul,
    I am new to the Galaxy Tab and so far have flashed successfully. I am trying to follow the above directions but I am running into problems. I have a micro SD which I put into my tab. I put the tab in Mass Storage mode and my android tab folders show up as my G drive and the memory card shows up as H drive. I created a folder “sdcard” in the H drive and extracted all files into it. I copied the file from /sdcard/modemswitch/switch.sh to /sdcard/gscript/ directory. When I run gscriptlite to load file I get an error “Error while looking for scripts in /sdcard/gscript/.” “java.lang.nullpointerexception”
    I would greatly appreciate your help.Thank You

  5. Lou says:

    Can you please email the file to me?

  6. Lou says:

    I cannot figure out how to do step 6. On my computer, Gscript is unavailable to copy into.

  7. Lou says:

    Okay after a bit of fooling around I have managed to follow your instructions to what I believe was correct. However, upon the last step, I noticed it did not reboot itself, so I rebooted, then tapped switch and it says stder: unknown operand, and,
    data/local/temp/redbend_ua: No such file or directory.
    ? What went wrong?

    Can you email me files please?
