Many app developers do not support this device anymore. You have three options:

1. Use previous versions of the app which were compatible with this device.
   (APKMirror.com hosts many previous versions of apps.)
2. Try the incompatible app anyways. It may run under NEON emulation. Emulation is very slow. The ideal way is to use previous versions of the app which are compatible with this device.
3. Contact the app developer and ask them to maintain support for Tegra 2 devices.

Got an error? Is something not working for you?

I cannot see what your problem is from here. Save and upload the system logs from your device so that I can see what happening on your device.

How to save system logs:

1. Root the device.
2. Install SysLog.
3. Reboot the system.
4. Reproduce the problem.
5. Open Syslog app and save the Kernel Log and Main Log.
6. Send me the log files stored in /sdcard/Syslog.
   Share the files on Dropbox or another similar site.
   Then PM me a link to the files. Please describe exactly what the issue is.

I don't have this device but it's more or less the same as the Galaxy Tab 10.1 which I do have.

Please send me logcat and kernel logs so we can verify that things are working properly.

Initial thoughts: WOW!!! Performance is great. Took quite some time to install then boot up but once it started it worked really well. Gonna root and try over clocking. Will post screenshots as well. A million thanks to you for this.

 

[L3R0N]

Overclocking hasn't been enabled yet but performance is good enough without it. For root to work you need to install the Phh Superuser app from the Play Store. Overall solid and stable. screenshots attached.
PS: screenshots via adb does not work but doing it physically on the device works fine.

I hope this is what you wanted. If it isn't then I can do again.

@decatf
Thx for this Rom, the first look it is smooth.
1. but if you open the Browser to open a web page it real laggy.It need a long time that you see the page.
2. Camera it is only the Front camera showing
3. USB Otg is not working in the Rom ( i ve used befor the Stickmount App from chainfire , but this worksonly with the SuperSu) , with the new TWRP yes.

Use Chrome. I don't usually use it but it does address the lag that's in the stock browser. Both cameras work for me, even the flash works fine.

My tab is a p5(with3g). I installed p5wifi twrp 3.0 then formated all to f2fs, flashed the rom, pico gapp, rooted. I user kernel audiutor to change cpu governor to interactive, io sched to deadline, enable ksm and set read ahead to 1024kb. Plus i downloaded tons of apps. Here is what ive seen so far:
-using kernel audiutor you cant overclockthe cpu or manage gpu freq
-both cameras are working fine until switvh to video mode then the camera app will crash
-chrome browser, ofcourse wont work and neither does microsoft office so i use firefox and kingsoft office
-youtube cant stream videos over 480p smoothly, but thats fine to me
-the tab can play 1080p offline video with software acceleration on mx player, with some lags obviously
-twrp 3.0 can be connected dirrectly to pc like a normal android, it even work with android file transfer on mac
-i installed tons of apps like facebnook, messenger, viber, firefox, twc, mxplayer,...... even avast anti virus and the performance is great, even wayyyy more awesome then stock 4.0.4, especialy the multitasking and slit screen is working good without a hiccup
-the animation is still a bit laggy and not the smoothest one but its acceptable
-this tab can still use multiple apps at once without being too laggy
-the batery report very correct and can be used constantly for 4 hours including download through wifi
-despite i have installed so many apps on the tab but it never keeps me waiting for a webpage to load and if no app running in foreground, it will idle at ~310mb of ram free
-lastly, i used asus zenui launcher on this tab(got from playstore) and it feels wayyyy faster and more beautiful than any other light launcher u put on this tab
=> bottom line: this rom plus twrp 3.0 made this tab felt so alive like never before. A VERY SPECIAL THANKS TO decaft for all of these but sadly, i m a teenager in vietnam so i cant donate any to you sorry.
Ps:this reply was written on p5 with android 7.0 and firefox browser.

 

[wavemaster02]

chrome 49 works

 

[wavemaster02]

For some reason I have lost the placeholder icons and app drawer icon on the home screen if the tablet is in landscape mode.

In portrait mode they magically appear.

Reverse to landscape and they are gone.

OMGGGGGGGGGGG After months of trying CM to boot, we have the KING Nougat How lovely
Please do share your setup for smooth performance and you can also share your status bar expansion hack with the developer to make the status bar pull down more functional

@decatf you are a genius sir

tried flashing the ROM with the latest open gapps 7.0 6th Oct and the google play services keeps FCing on the setup itself. Cannot go ahead with the setup :/
maybe the new play services 9.8.75 is to blame

 

[lallolu]

Youtube and googleplay force close everytime. I have factory reset but it still happens. I have not tried other apps.
