I can just second the previous post - Kudos to the developers and to this thread! Thanks to it, the world has been saved from some electronic waste.
As thanks, I'd like to add my two cents to this thread:
After following all the instructions I could find (including overclocking), I still did not think the overall performance was acceptable. It was simply too slow in everything I did with it. As some people reported being OK with the performance I spent hours fiddling around. I tried disabeling Google Play Store and Google Service too, but did not help.
What I did find to help was to do a clean install of the ROM and not install Gapps. That made a significant performance improvement! It's still not even close to a modern tablet, but now it's acceptable.

If you don't have Google Play (just as me), I recommend getting the F-droid app store. From there, you can download additional apps, especially:
  • Kernel Adiutor - for overclocking
  • APK-mirror - yet another app store to get most of the apps that are available via Play Store.

Hope this helps someone! :)

Just as you do, the only option for me is to use the tablet without gapps.
Just wanted to add that Aurora store also may be a good option to get apps. It doesn't depend on google services and you may install all the apps from the market.

Also with hope to help someone who uses this old but still able to work device.:cowboy:

Thats what I posted in previous post, use alternate Apk Stores, Apk pure or other.
Install magisk from decatf and than install KernelAuditor for OC the CPU to Max 1400 MHz to give this Tab more performance .

Yeah, I guess it's related to their new servers which also disabled new uploads.
I've been able to download it through a server of mine after some tries. I can load them now as well, before that I've only got "no mirror found" as my screenshot was meant to show.

Thanks for testing them though ;)

    Incompatible/unsupported apps:
    Many app developers do not support this device anymore. For these apps 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.

    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.​

    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.
