Build 20170307

Changes:

- Update to android-7.1.1_r24
- Substratum theme engine
- Signature Spoofing
- kernel fixes

I've add signature spoofing in order to support using the microG Project. It's an open source implementation of Google Services. Read more here: https://microg.org/ and here

In order for it to work microG Services Core needs to be installed as a system app. This can be done with /system/app mover.

Hi decatf, I've install yesterday the last version for p4 wifi, and pico Open gaps from 29 December, using TWRP, full wipe.

So far no problems, even the playstore services problem doesn't ocurr until now.

Thank you very much :good:
[Galaxy Tab 10.1 Android Development] mcduffie2010:
Can you post a link for the gapps please
[Galaxy Tab 10.1 Android Development] Macfly60:
Works fine too for me.

But i didn't try microG Services Core because, if i understanded well, Plays Store will stop working ?
[Galaxy Tab 10.1 Android Development] ps.m:
p7500 status as of 20170307 build

launcher3: I disabled the (google) search bar app, despite of this the search bar remains on the screen, solution: switch to nova launcher and disable it there

"CLEAR ALL" button appears only if the last background app is left, would be nice to have it when I enter the list of last running apps (square button on the right to HOME)

battery status: as reported by others as well, the battery status is not reliable: let's say, I have battery loaded at some value < 50%, sometimes even so low, that it goes into minimal usage mode (dropping display brightness...). I connect it to AC power, it changes status to charging, sometimes even telling me, that this will last 1-2 days or many hours, far too much for a real situation. After 8 hours of charging (over night, when it tells me, that it needs some more hours, days), the charger is cold (not charging anymore, although the tablets means it is charged...) I disconnect the charger and reboot. It says now 100% loaded. It is really charged and I can use it again for hours/days depending on usage/apps. It seems, that during the charging the status is not updated everytime. The only cases, when charging changes the status "correctly" is when I have > 50% capacity and try to recharge, but it does not happen all the time, sometimes it fails even having 80% and trying to recharge it. Some earlier reports tried to describe an unusual status of the battery, I can understand, that all these reports were somewhat unprecise, there is no correct way to describe this "unstable" behaviour.

Thanks for your devotement to this project.

---------- Post added at 09:32 PM ---------- Previous post was at 09:16 PM ----------

decatf: How did you make it usable?

It does not work for me. I have moved microG Services Core with app mover making it a system app. Cleared (dalvik)cache in recovery and rebooted. The Lanchon-SigSpoof-Checker-1.0.apk app tells me, that signature spoofing is disabled. How did you get it enabled?

[Galaxy Tab 10.1 Android Development] rubbercorners:
Yes, it seems like there's several posts with suggestions, and then a couple of posts later someone says "nup, crashing again". Would be good if someone could post a link to a definitive step-by-step.

Mine isn't crashing at the moment (fingers crossed). All I know for sure is you have to turn off Play Store autoupdates,

and you have to roll back to Google Play services 10.0.84 by uninstalling the update only in

Settings > Apps > Google Play services

(I think I went to the top right corner (3 dots) and had to change the Administrator Permission setting to unlock this option. I think some people just pressed the Disable button and the option came up. If you can't find the downgrade option, I guess you could uninstall the app completely and then install the 10.0.84 apk in the original post link).

Then I think someone said you also need to:

Settings > Apps > Google Play services > Data Usage > Unrestricted Data Usage (turn off).

Then I wonder if you have to also uninstall certain other google apps.

I am trying to install on my 7510. Installed twrp 3.0.3. then i get the following

Installing zip file '/sdcard/aosp-7.1-p4wifi-20170214.zip

checking for MD5 file...

skipping MD5 check: no MD5 file found

Target: samsung/GT-P7510/GT-P7510:4.0.4/IMM76D/UELPL:user/release-keys

and once it hits this, the progress bar never even begins showing percent completion. the tablet just keeps acting like it is grinding away with no progress change. the tablet does not crash.

Any ideas? perhaps my rooting is improper? I just got the device from my father which was running 4.0.4. I rooted and this is my first ROM i am attempting to install on this device(have successfully rooted phones before with no issue) i do have super user in the programs after the root i attempted. I would love to get this tablet running on 7.1.1!!

ROM doesn't install on 7500

Hi guys,

I am trying to install the latest build to my old P7500 tab with TWRP 3.03 (20170120).

The ROM installation seems to get stuck on the line where it says:

Target: samsung/GT-P7500/GT-P7500:4.0.4/IMM76D/XXLQ8:user/release-keys

I left it there for more than 90 minutes, but nothing.

My steps are:

Enter TWRP

Advanced wipe cache/dalvik cache, system, data

Install ZIP

Any idea why it wouldn't go on?

they all error using CWM.

I then installed twrp 2.8.7.0, much nicer interface, but they all still error out. I'm back running 5.1.1 without any problems. Is there a new version of twrp that I need? I've been going back and forth on these roms for two days without success.

Could it be a problem specific to the P7500 build? If a more senior member could chip in....?
[Galaxy Tab 10.1 Android Development] tmsiqueira:
Well, after some research I found the following:

Android version 2.3.x (Gingerbread) Deprecation from https://developers.google.com/android/guides/releases

Google Play services 10.2.x is the first release that no longer includes full support for Android version 2.3.x (Gingerbread). Apps developed using SDK release 10.2.x and later require a minimum Android API level of 14 and cannot be installed on devices running an API level below 14. To learn more about your options, including building multiple APKs to extend your app's support for Android Gingerbread, see the Android Developers Blog..

So, Google are discontinuing support for Gingerbread and Honeycomb in Google Play services.

Build 20170320: The End

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

Changes:

- 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.

Please (PLEASE) let us know which tablet you get to replace your dead tablet. ESPECIALLY if you decide to port AOSP code to it.

Install twrp2870-20150814-p4.tar.md5 using Odin

Flash aosp-7.1-p4-20170320.zip

In twrp, install superuser.zip
