evga note 7 android 5.1 ota 3.0 download Fixing Lollipop 5.1 on the EVGA ? When my wife and I first updated our EVGA Tegra Note 7 to Lollipop we found this once very-fast, cool, and battery-sipping tablet became unbearably laggy, hot, and power-hungry. We found this odd because we own the Shield Portable with the same SoC and 5.1 Lollipop runs great on that device. This is just a guess, but we think the problem of accumulated system or user data slows the little tablet down because the Note 7 only has half the RAM (1GB). We tried to resolve our issues by performing a factory reset. Unfortunately this did not work. However, we were not beaten yet. Read on to see how we got our little tablet to work well with Lollipop 5.1. Disclaimers. Important : This solution is only known to work for my EVGA Tegra Note 7 WiFi model, TegraNote-P1640 as shown in Settings > About tablet > Model number . Attempting the solution on a different model could likely brick the device. There’s even a chance attempting the solution on devices with the same model number could get bricked. Proceed at your own risk. I also encourage readers to review the excellent XDA ROMS work from William Rogers for alternate solutions that may be a better choice for their model or situation. The solution. Our initial intent was to download the OTA 3.0 GMS recovery image from downloads page and install it. While there is a link for the OTA 3.0.0 ROM, the link is broken, and it is for the P1988/P1988W model. Instead we decided to load the “OTA 2.5” image and then try updating to Lollipop using OTA. And it worked! Once we had finished the tablet runs much better than the previous Lollipop install. As an added bonus, if we want to revert to KitKat 4.4 (“OTA 2.5”) - which is an excellent ROM - we can do so in 10 minutes or so. The entire procedure took less than a half hour. Here are the steps we took: We unlocked the boot loader using the instructions. We then installed the NVIDIA Tegra NOTE7 GMS Recovery OS Image (OTA 2.5) from the Nvidia downloads page per the instructions. We used the the root account on Linux to avoid any device access permissions issues. Once we flashed all the images using the flash-all.sh script, we had to select continue on the tablet’s bootloader menu and press the power button to continue with the update. When we signed-in for the first time we disabled BACKUP & RESTORE to minimize update time. We also disabled the For improved accuracy . option to maximize battery life. Once our initial sign-in was complete, we allowed automatic updates to proceed. It took about 15 minutes for all apps to update. We had to approve 5 of them. Because we had disabled BACKUP & RESTORE earlier, we probably saved time by avoiding downloading and updating data and applications. Immediately after all updates were applied, we clicked on the OTA 3.0 update in the top-left corner of the screen and pressed Restart and Install . After the OTA was complete - in other words, Android 5.1 had been installed - we went to Settings > Backup & Reset and enabled Back up my data and Automatic restore . We also created a power-control shortcut using these instructions. We optimized all apps, and we turned off WiFi during sleep. This is important to maximize battery life and reduce heat ! We found that adding a second account reduced performance noticeably. This is probably due to the limited RAM. Just to be safe, we repeated this procedure using my wife’s account as the primary and only account. We have found the upgrade to be very much improved. The tablet is responsive and cool. The battery life is good again, and it charges completely in under 2 hours (using a Shield charger). Parting thoughts. One thing we really appreciate about Nvidia is that they usually provide some of the best Android support outside of the Nexus program and Motorola. Our family have no carrier contracts and we own all of our Android phones and tablets - Nvidia, Nexus, Moto, , and EVGA devices, in that order. So we were really jazzed about the Tegra Note 7 getting the Lollipop upgrade because it had been overlooked for the last year. It’s too bad that we had to wrestle with the problem, which we suspect affects the early adopters more than recent purchasers - there is some evidence that more recent Tegra Notes perform very well after the OTA to Lollipop. We wish Nvidia would do a bit more to own this problem, because as the above experience shows, they are so close to having a really great update for everyone. Downgrade to kitkat from lollipop. 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. ------Post added at 10:15 PM ------Previous post was at 10:14 PM ------NVIDIA CodeWorks for Android.

So I remember my excitement when I saw that my beloved Tegra Note 7 showed me that the 5.1 OTA is available. Needless to say, the excitement died down after a week or so of using the tablet. The problem that bothers me the most is battery drain. In just about 10 hours in standby mode with WiFi off, my battery reduced 13%. I take it off the charger at 100%, WiFi on, in standby mode and viola, in 10 minutes, 3-4% battery drain with no activity at all. Now I hardly get more than 2-3 hours of activity out of it but when I was using Kitkat, oh boy. 2 days in standby with WiFi off and 1-2% battery loss. Amazing. Also, I miss the power control so much <3 (I really don't think the Activity Launcher way to get the SHIELD Power Control Menu works at all) Now I really want to downgrade it to Kitkat but have absolutely no clue how to do so. I'm not rooted currently and I've tried searching in the forum for existing topics for but couldn't find any. It'd be great if someone wrote a 'For Dummies' guide as to how to downgrade from Lollipop on an unrooted device in the simplest way possible. swaaye. Senior Member. Sep 28, 2015 at 6:51 PM #2. Yeah Kitkat is better than Lollipop at the moment. You need to get a custom recovery on it and flash one of the stock ROMs. You don't actually need to root Android for any of this. The "Super Tool" will get the custom recovery on it (CWM or TWRP). Note that you will lose all data on the tablet when you unlock the bootloader. Also, the NV USB drivers for Windows are unsigned and so you will probably need to boot Windows into a mode that disables the driver signing check (Win8/10). http://forum.xda-developers.com/showthread.php?t=2627654. Then you can put one of these stock ROMs on a SD card and flash them within that recovery. It's very easy to go between ROMs this way. http://forum.xda-developers.com/showthread.php?t=2777254. And of course be warned that there is always the possibility that something could go horribly wrong and kill your tablet. It went smoothly enough for me though. SgtEnigma. New member.

I'm not so sure how I feel about the screen on time as I was expecting more since I've kinda forgotten how KitKat was originally. Anyway, a run time of 1 Day and 12 hours with WiFi on 75% of the time and a screen on time of 2.5 hours is miles miles miiiiiiiiles ahead of Lollipop! (22% Battery remaining). I'm back to the Antutu benchmark of 35K vs Lollipop's 40K/40K+ I'm mad for theoretical performance so I kinda miss that having those beautiful numbers flash on my screen. Regardless, I'll take much much better battery life over those 'numbers' any day of the week. Enough time wasting, lets get on with the guide! (I'm sure this has been posted before but I'll try to cover 1-2 of the issues that I encountered that others might too) STEP 1 - Download Nvidia Tegra Note 7 Super Tool 2.5.zip (Android 4.4.2) I downloaded version 3.0 but that only restored to Stock 5.1. I'm not sure about the versions between 2.5-3.0 as I randomly downloaded 2.5 and it worked so I didn't bother checking the others for Android versions/software changes. STEP 2 - Go to Device Manager -> Go into the properties options of the Tegra Note (Right Click) -> Hardware -> Properties -> Hardware -> Driver -> Update Driver -> Locate Drivers Manually -> Locate the folder MicrosoftWindows_NvidiaUSBDrivers_Rel20131017 in the extracted folder of the downloaded Super Tool 2.5 -> Include SubFolders and viola! The software should now be installed. [I’M NOT ENTIRELY SURE IF OPTION 1 IN THE SUPER TOOL– ADB & FASTBOOT DRIVER INSTALL DOES THE SAME THING SINCE I INSTALLED MY DRIVERS MANUALLY. ALTHOUGH, I THINK IT SHOULD DO STEP 2 BY ITSELF] STEP 3 - Just unlock your bootloader and restore to 4.4.2 with the help of this video (youtube. c o m /watch?v=oAp-P-yUSaA)
