I "inadvertently" wiped system on my tablet with adb. No critique needed. I've already called myself all the names. What I need now is a way to put at least the "sh" program back on using adb or other program with “x” permission so that I can adb shell once again. Currently, adb removes the “x” permission when using the push option. I examined the adb source code and found one line in the sync section that seems to change permissions to 644. This is a project/challenge to recover this brick. I already have a replacement. Any solutions are welcome. Motherhood comments are not necessary please. Thanks.
P.S. The recovery mode is not working on this tablet (i.e. pwr/vol+/vol-, fastboot, etc.).
