How can I root the Samsung GT-P7510? I've tried z4root and many others, but they all seem to support Android 3.1 and not 3.2. I gather 3.2 is specifically designed to eliminate the exploit that z4root and others depend on.
You will need to flash a pre-rooted 3.2 ROM onto your Tab.
A Google search brings these instructions for installing a custom Recovery:
The instructions go on to rooting Android 3.1, so you will need to slightly alter those. Instead of using the "root" ZIP included in the package, you will need to obtain a pre-rooted Android 3.2 ROM. There are many such ROMs available on XDA-Developers forum, so take your pick (e.g. this one,) download the ZIP file, and copy it to the SD Card.
Continue on with the instructions to reboot into the ClockworkMod Recovery:
You will now need to perform a factory reset/data wipe to avoid any compatibility issues. With the volume buttons for up/down, navigate to "wipe data/factory reset", and select it by pressing the Power button, and then scroll down to and select the "Yes" option. Once that operation completes, you can continue with the instructions, substituting the file name they are suggesting with the one you've downloaded:
According to some comments this method should work on the WiFi-only model of the Galaxy Tab 10.1 (GT-P7510). However, you might encounter issues transferring the downloaded files onto the Tab. A comment suggests a work-around:
Yikes. I'm glad I didn't find this answer when I searched for a way to root mine.
Otherwise it's similar to the other answer. You can root your tab without losing anything. This works fine for 3.2 systems - for probably Samsung's last 3.2 update, before their year 2056 release of the ICS update.
(If you then want to install CM9 or like, you'll do the data wipe anyway, but there's still this advantage to this method: after you root the tab, you can use ROM Manager to install CM9. When I first tried to install CM9, the script failed with a bogus error, and then the nandroid backup also failed, leaving me half of a stock install. Very tense period there, before I installed ROM Manager and it Just Worked(tm).)
