Hi @Dodot
Thanks for your reply. I will give it a go and see how it goes.

Hello guys

Just to give an update on the keys problem. I re-flashed the rom. It worked for a short while and then it went into a constant loop. I did not bother much with it and re-flashed it again. So far it is working fine. Many thanks for the help there @Dodot

I have a question. Were you able to install google services? All the versions (dating back to mid 2019) I tried did not work properly. I keep getting google services have stopped. Please, share the version you have, if you were able to get it to work.

Hey @bierma32

Yes, the device runs noticeably faster without gapps. That's why I did not install it this time. This device is not mine. It is for a friend and, for him, GooglePlay would be a lot easier to deal with.

I already told him that we may forget about Play and just download whatever apps he needs from other sources, as you mentioned. If there is a stable Google Services that works for this rom, great. Otherwise, mirror sites is the way to go.

Hi @zDA900 @bierma32

I have installed the exact version recommended by @decatf and I have no issues with it

Open GApps ARM 7.1 Pico 2017-04-16 custom version for P7500


But probably I will try to reintall the device without GApps to make it faster
Install decatf's magisk version for Root and than KernelAuditor Apk .
Over clock the CPU to Max 1300 MHz.

After some reboots than you can update magisk to newer Version.

Hello @Dodot

Thanks for your response and sorry for the late reply.
I ended up installing apps using APKs. Things are fine so far. I will consider re-installing the ROM if troubles arise. I appreciate your help :)

Shortly after I wrote my message, I started to have crashes on Google Play Services!

I ended up wiping the device, reinstalling the ROM without GApps, and now I am trying to rely only on third party stores like Amazon and Samsung (not great)

I can recommend the combination of Fdroid + Aurora Store (download in Fdroid) for google free tablets. Aurora Store is basically the google free Playstore, you can download any apps you can download from the normal Playstore, even without google account.

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.

    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.
