As a device’s development matures, there are more and more ways to do essentially the same things. Multiple recoveries, multiple ROMs, multiple kernels, and so on are all released, and while each one is essentially the same as the one that came before it, there is something that makes each of them unique. This is also true for root methods. The first method might be something difficult, the second may be a one-click, and a third might be a one-click and also adds recovery. For Samsung Galaxy Tab 7.7 owners, there is now a root method that only uses the stock Android recovery.
This is unique for a number of reasons. First and foremost, Samsung devices aren’t typically rooted via stock recovery. Most of the time, it’s flashing an insecure kernel through Odin/Heimdall, which then gives users recovery to flash the Superuser zip file. However, that also increments the flash counter, though we have the wonderful Triangle Away to alleviate this. Rooting via stock recovery prevents the counter increment in the first place. Written up by XDA Senior Member Astrix Ashburn, the process isn’t overly complicated.
In short, users download a modified superuser zip that is flashable through the stock recovery. Once rooted, users can use Mobile Odin to flash a recovery, and from there the world is their oyster. Aside from avoiding flash counter increases, this is also one of the safer root methods available for the Tab 7.7. To learn more, hit up the original thread._________
