hello everybody,
I installed the rom for the p5 (3g data), but I'm not able to turn on 3G data, any tips?
BTW Congrats to the developers, the rom is very good, I haven't seen this tablet perform this well in quite some time.
You need to add an APN under "Settings -> Wireless & Networks -> More -> Cellular networks -> Access Point Names -> (+) sign at the right top corner".
All I had to do was this:
name: some name (e.g. carrier name)
APN: internet
APN type: default

Search on the web for your country and carrier specifically (generally they send you metadata automatically, but apperently it won;t work in this ROM).

P.S.: I had to power off and on rather than a reboot for the tab to recognize my SIM card.

Download link See Post #550 and #556
Thank you for the link. I have already succeeded and entered a new system. Now there is a question, what should I add to achieve the overclocking function.

Install the V18 Magisk Version from decatf and after some reboots you can update to the newest magisk Version.

Backup up your boot.IMG in case it goes some thing wrong.so you can restore this.
Max OC 1300 MHz.

Everything in this system is fine. There is a fatal problem. The charging becomes unusually slow. When I plug in the charger, the system prompts that it is not charging! But the icon shows the charging status!

      (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.

    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.
