First off, I would like to let everyone know I'm not a total noob. I've successfully rooted and custom ROM'd an HTC incredible, droid bionic, HTC Rezound, and the DROID RAZR Maxx. With that being said, i am now running into some issues with my Samsung Galaxy Tab 7.7 i815 from Verizon Wireless. I successfully rooted the device, which was not very difficult to do. The problem I am running into, is trying to get ICS on the device.
I have downloaded Odin mobile, but have never worked with Odin before, nor do i know anything about how it operates. Everyone seems to be talking about some kind of .tar file. I found it, put it on the root of the SD card, but can't seem to get it to flash. Likewise, when I try to access Odin, Superuser will grant me permissions, but then the app (Odin) will tell me I do not have access to it. To top it off, I can't seem to get clockwork recovery to work so I can try and flash any kind of custom ROM, or to put the custom recovery on the i815.
Long story short (too late), I am VERY unfamiliar with how the inner working of tablet customizing goes (I'm sure it's not a huge difference from rooting a phone), and I'm looking for anyone who can help explain to me using small words and typing slowly so i can understand in lame man's terms how to fix this issue, it would be hugely appreciated.
Lastly, I have searched the internet, including google searches, and there aren't really any helpful topics of discussion that you can understand without an engineering degree, which is why I'm hoping someone on here can help me out in a simple, english speaking version. Thanks again for your time everyone!
