On a Galaxytab 7.0 Plus N, I have Superuser 3.1.3 with su 3.1.1, according to the "About" etc. screens I could find. This has been installed via SuperOneclick about a month ago. I did it this way because I like it non-intrusive, I don't want to install a complete new ROM with less bloatware, more cool features but also new bugs.
This root installation is still partially working, but seems to be accumulating breakage.
My first root app, NTPsync, seems to get root access according to logs, but the time is off. If any other app tries to get root, it hangs for a long time until killed with a Task Manager. I have disabled Superuser notification (since then the menu option is grayed out), and I have disabled the prompt (set to allow always), with mostly no change (but some things seem to fail faster now).
When i call su in Terminal, nothing happens until i use Ctrl-C twice, then it says "Permission denied" and logs a "Denied" entry even though it is set to allow always.
In Root File Manager, when I try to access the /data directory, nothing ever happened except that it hangs for some time.
I installed SuperSU. This fails to install its su, hanging forever. A few other root operations hang forever too (until killed), notably 2 root checkers.
What could be wrong? Did this happen to anyone before? When I read other questions, it seems devices are either rooted or not, but they don't hang forever on the question like f(x) in Recursively enumerable set - Wikipedia, the free encyclopedia
Should i try to re-root it? if so, how?
For rooting this device, I think I installed Clockworkmod recovery first (placed it on the sd card, booted, followed some instructions), then just installed superuser from the market.
