Incompatible/unsupported apps:

  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.

Installation:
  1. Backup all data
  2. Install TWRP 3.0
  3. Wipe cache, dalvik cache, system, data
  4. Install the ROM
  5. Optional steps:
    - Install gapps pico
    - Install phh Superuser
  6. Boot the ROM
  7. Enable on screen keyboard by toggling "Show input method"
Installation issues:
- If it freezes when installing the ROM then use TWRP 2.8.7.0.​

Error reporting guide:

Saying "it doesn't work" is not helpful. 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 Google Drive or another similar service.
    Then PM me a link to the files. Please describe exactly what the issue is.

Hi decatf,

first of all *thanks a lot* for bringing Android 7 to our device, this is brilliant! Quick question: any specific reason that you suggest phh's SuperUser instead of Chainfires SuperSU?

Kind regards,

mistersixt.

Ok, looks pretty promising already, the steps I did:

- Ran Titanium Backup for all user apps
- Rebooted into TWRP 3.0.0.0
- Full wipe
- Installed aosp-7.0-p4-20160929.zip
- Installed todays OpenGapps (pico)
- Installed phh's SuperSu
- Reboot
- TitaniumBackup first did not get root access
- Installed phh's App from Play Store
- Reboot
- Titanium Backup does get root access now

So far it feels smooth, no errors or force closes... I am pretty impressed :) . I will test the SIM card this evening as I don't have a spare one with me right now.

Thanks again decatf!!!!

Kind regards, mistersixt.

Ok, first small issue: I cannot get AdAway adjusting the hosts file, when trying to flash the AdAway systemless package in recovery it fails with error 4 or something (although I don't know whether the systemless is necessary here), and when running the AdAway App itself it fails with:

Hi decatf,

Kind regards,

mistersixt.

SuperSU doesn't work anymore on this device. Chainfire sold it to CCMT. Some shadowy mysterious group. So who knows what kind of support it will receive from here on out.

phh Superuser works. It seems that some apps can't detect it right. It's the only option that works right now.

To use Adaway you need to mount /system as read/write.
Code:
mount -o rw,remount /system
Install hosts file.
Set /system back to read-only.
Code:
mount -o ro,remount /system

[/CODE]

Thanks a lot, that did the trick.

One more thing: I cannot overclock the CPU, although Kernel Adiutor is showing a max frequency of 1400 Mhz for example the CPU is stuck with a max frequency of 1000 Mhz, and here and there I see messages like:

Code:
E P3 PowerHAL: Error opening /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq: Permission denied
.

It works for me.

Kernel Adiutor sets the permissons on that to read-only for some reason. The default in Android is r/w (0660). So it ends up preventing everything else from using that sysfs file unless they also change the permissions before writing it. This breaks the default behavior. Kind of strange.

Code:
# logcat -s "Control"
09-30 11:25:43.201  2965  3172 I Control : chmod 644 /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq

    Good news. @mainlane has sent me a P7500. So this ROM is not dead yet.

    I will post a 7.1.2 ROM soon.

    Build 20170320: The End

    My tablet is dead. This is the final release from me. So long and thanks everybody.

    Changes:
    Code:
     - NEON emulation

    This build enables NEON emulation. It is very slow but some apps do not use much NEON code so these such apps are mostly useable. Apps that rely heavily on NEON code are too slow to be useable.

    Emulation is CPU and battery intensive so use it sparingly. I suggest you stick with previous versions of apps that do not use NEON unless there is some feature you desperately need.

    In case you didn't know yet, Google Play Services 10.5 beta seems to running without any NEON code so I highly suggest you install that too. There's a link in the second post of this thread.

    I will release an Oreo ROM but it only works on newer kernels which need to be tested first.
