Ok, From now on if i see people asking how to update / how to keep root im going to link you to this thread, im tired of answering it.
This works if you are on
STOCK RECOVERY. If you are
unlocked there are lots of other options for you (such as flashing a rooted kernel) so go to development and find that. Since im not unlocked i had to do it the hard way. This method works if your OTA updates are screwed up. If you HAVE OTA updates you can just use OTA rootkeeper to backup and disable root, make sure all stock apps are restored, and proceed with root.
Note for the updater: The OTA updater is a DIFFERENCE updater, if files are missing or different versions the update will fail. Best practices say to update sequentially, never skip an update. It might not cause problems now but could cause problems in the future.
If your OTA updates have failed or for whatever reason you can not get OTA's, you have a LOCKED bootloader, or for whatever reason want to manually update and keep root then this guide is for you. Also please note the process for going from .16 to .18 is the same as going from .30 to .16.
First: Make sure you have all
stock apps restored, no custom build.prop, etc.
If your not sure, wipe the tablet and reinstall. Better safe than sorry.
Make sure you are ROOTED. Use whatever method works for you.
Now would be a good time to make sure superuser is updated, mine was old so a quick update on the market and its all good.
Use OTA Rootkeeper to backup root
Download the DLPKG file apropriate for your version.
If you want to update to JB you must have .30 installed and download the .16 file, WW or US, depending on your region. Other packages are provided for convenience (This method can be used to spoof the OTA update to any version as long as you have the file)
DLPKG for .26 WW
HERE
DLPKG for .30 WW
HERE
DLPKG for .16 WW
HERE or
HERE or
HERE
DLPKG for .16 US
HERE or
HERE
DLPKG for .18 WW
HERE or
HERE
DLPKG for US .18
HERE
(Make sure you only take the file for the version you want to update to, only one step at a time, so if you are on .30 WW you need .16WW before you can do .18WW)
You will also need the command file

HERE
Transfer the files to your tablet using the USB cable.
Once the files are on the tablet use Root Explorer or your favorite root file browser to move the two files
(NOT THE STOCK FILE BROWSER IT CANT SEE THE ROOT DIRECTORY)
"command" goes to /cache/recovery
"dlpkgfile" goes to /cache
Make sure the files are named exactly as shown above. No capitals, no file extensions, etc.
Make sure the permissions for both files are changed to
RW-R-R for both.
Go into OTA Rootkeeper and
TEMP UNROOT.
Shut down the tablet. Remove the USB cord. Remove any USB memory sticks. Eject your Micro SD card. UNdock the tablet. Lets not let anything go to chance.
Press and hold both the power and volume down buttons (volume down is closest to the power button in case you forgot like me)
Soon as the splash screen comes up you should see some text on the left side, release the power and volume down buttons and press volume up.
Now just sit back and wait, this can take a while. I got myself a snack and took this time to stretch a little.
Once your all booted up you should be running JellyBean. Open OTA Rootkeeper and restore root.
Please note i did not come up with the steps in this guide. I did not originate the files. I am nowhere near smart enough to do all this on my own. I meerly collected the information and links to files and pieced it all together. I wrote this so even my father could follow these instructions so hopefully you all succeed! If something needs clarification please let me know.
- Edit -
Added notes on restoring tablet to stock.
- Edit -
Added .18 links. Thanks to xcal321 for providing them.
- Edit -
Cleaned up the guide a little. Hopefully its less wordy and easier to follow.
- Edit -
Added links to my personal google drive for nearly all the files, should have no problem for overseas users with limited access to mediafire
