I recently upgraded to ? and was disappointed to say the least so after looking around there are number of ways but all seem complicated so here is the easiest way which works for me

Flash at your own risk

My version P1640

1. Flash twrp recovery with flashtool or adb
2. Do a nandroid backup
3. Flash this http://rootjunkysdl.com/?device=Tegra Note 7&folder=Rom Stock 4.4.2-2.5
4.wipe dalvic etc then reboot

This rom is not compiled by me but is rooted

Lollipop is good but you need to tweak it to get it back to earth.

* Make sure your tablet is OEM unlocked. Then flash a sophisticated recover image version like TWRP. This will allow root-mode enabling via a patch.

* Put the tablet into fastboot mode and flash RootJunky's shared Lollipop restore image instead of the upgrade over the air (OTA). Good idea to erase particular partition before flashing.

* Boot to the recovery stage. Install latest zip SuperSu.zip using sideloader or having it already on a SD. This will enable root mode.

* Start system. Remove Apps from system partition unneeded, or that can be moved or installed to user directory instead. This frees up vital space. Example Lollipop only leaves a few megabytes left in the system partition after installation. Consider using Link2SD. Example get Google+, Google Play, Google Magazine, etc into the user partition and any other big App off your system parition. The system partition should only have important apps needed to be retained if a factory wipe is enacted.

* Then go through all your system settings make sure you tweak them to suit both power saving and your own desires.

* Use a startup tool like ES Task Manager to remove apps starting that don't need to be running from system boot.

* Install all Google Apps wanted. This can help to configure the system how it's meant to be.

* The system should now run smooth and use little battery.

With a bit of manipulation I replace the Launcher to Google's Now one.

Thanks a lot!
LP 5.1 was a waste of time and resources. Apps freeze randomly (even after factory reset etc) and there are just better UI options in KK for now.

Oh man! I flashed this on top of 5.1 LP as your instructions but now its in boot animation from ~11 minutes now! :eek: Any other formats had you done after flashing this over LP like factory reset from TWRP?
Fk me! I cant even get into recovery by poweroff+volume up!! It just switches off then boots back on and goes into the bootlogo powered by tegra. How do i atleast switch it off until something is figured out? Its just getting hotter and stuck on bootloop :(
How do I flash it back to 4.4?

Last night I went into TWRP to fix permission since seemed like something was wrong with Lollipop and my TN7 went into a bootloop also. Couldn't get into recovery so I let the battery drain, recharged, and was finally able to get into TWRP. Flashed Tomsgt's 5.1.3 but before rebooting from TWRP it stated "No OS Installed! Are you sure you wish to reboot?" Of course I rebooted anyway and now the tablet is on but it's a blank screen. I hold the power button and the message "Power Off Device" does show up, so that's odd. Ended up flashing Stock-4.4.2-2.5 and it's finally back!!

Loved this tablet initially when it didn't stutter/lag so much, and I know the hardware is supposed to be more capable (other than the 1GB of ram). I don't game on it and don't do anything intensive. Don't understand why it would lag so much...

There are no differences between the brands, The only difference is the boot image and the name of the brand behind the device. the supertool will work with any brand:) (i think so) and if you use supertool to downgrade there should'nt be any issues (i think so i am not sure:angel:)
