When I try to use a BT keyboard, it stays at PIN enter screen. Anyways, great ROM!
[Galaxy Tab 10.1 Android Development] JulianJenner:
Hail Dude! I found my old 7500. I found decatf's nice work. I have TWRP 3.0 on Tab.

Made full wipe (absolutely full!), transfer ROM to Tab, install, success, boot normally, but Setupwizard crashes after second step, so I can't use my tablet.

What is my fault? Please tell me.
[Galaxy Tab 10.1 Android Development] Tenstron:
Yeah I had the same problem - basically you installed the wrong version of gapps. Make sure you get the 20170406 zip, not the other one. The only way I could get out of this problem was to install the rom again from recovery. I checked that it worked. Then booted into recovery again and installed the right gapps
[Galaxy Tab 10.1 Android Development] JulianJenner:
I think nope, because I got this issue when I installed ROM only... :crying:

Then, OK, I will try.

Update: Thanks for your help. I don't understand, but second attempt is success.
[Galaxy Tab 10.1 Android Development] Tenstron:
Oh really? The time that I didn't install gapps I somehow got through to the home-screen without that setup wizard. Did I get lucky or something?

Hello everyone!

I can not update SuperSU on my p7510, I installed it well but it marks me "SU binary occupied" all the time, I tried 3 different and that of Chainfire but it does not work.

[Galaxy Tab 10.1 Android Development] decatf:
Magisk 13.2 and 13.3 are working for me. Otherwise post the recovery log (/tmp/recovery.log)

The battery drain in power off is some hardware bug. Reboot to TWRP. Then power off from recovery. It will usually power off properly from recovery.

decatf, no new build?
[Galaxy Tab 10.1 Android Development] jaibar:
No, not for people who do not care to read the last two pages, where decatf posted build status.
[Galaxy Tab 10.1 Android Development] jephimax:
If you've read the dev's posts, you would not encounter those errors. Since you've said that you are totally new to flashing ROMs and the like, I'd recommend you read and follow instructions to a T. This ROM is actually stable IMO.

I'd say that you try those ROMs out yourself, because you can judge for yourself what fits your needs for a stable ROM.
[Galaxy Tab 10.1 Android Development] tomi_cc16:
Hello,

thank you for your answer - so it's working now - I tell you what I did:

1. Wipe cache, dalvik cache, system, data

2. Reboot into TWRP

3. Installed all three zip at once:

- aosp-7.0-p4-20160929

- p4_kernel-aosp-7.0-20161002

- open_gapps-arm-7.0-pico-20160930 (took the older one that is working above and I think that was the solution)

Now Google Play is working - instead of Chrome I took now Dolphin and downloading is working perfectly. I also tried youtube from the Google Play store but its working without any problems (or would you recommend to downgrade youtube manual because of the NEON thing to an older version?). Also tried the google search app - it's working - but a little slow. (would you recommend to deinstall it because of NEON?)

The only error I still get is when I use the internal Internet Browser to download a file, everytime "...services has stopped"

So good so far and thank you for the quick help!
[Galaxy Tab 10.1 Android Development] nwo122383:
You need to go into settings--> applications find the browser app and go under permissions and allow it access to storage and that should fix that. In android N you have to give apps permissions. So generally when i have an issue i go and check the permissions to see if that is the issue. Hope this helps.

Nice thanks!

I confirm that... even the opengapps from today are not working for me... but, as mentioned above the gapps from 30/09 works fine!

Thanks!!!
[Galaxy Tab 10.1 Android Development] decatf:
I am not able to reproduce any crashes with opengapps pico 20161007 or 20161009.

Make sure you don't install Chrome 50+ or Android System Webview.

It does perform poorly. I think it's always been like that on this tablet. I don't know what the deal is with it. Maybe it's the hardware or maybe something's buggy. I have never come across anything that might hint at something wrong.
[Galaxy Tab 10.1 Android Development] cravingrom:
Thank you, Thank you for the rom. Cant believe i can breath new life into my p4. Everything

is working great for me. Havent had any major issues other than what was expected. Wifi seems the same as before, not all that great. It works. Only thing i noticed maybe just me

is the sound level seems lower. I know voodoo is baked in, tried installing voodoo app also but still seems low. Maybe just my hearing!
[Galaxy Tab 10.1 Android Development] decatf:
Looks like the recent gapps are using APIs that are only available in recent versions of chromium. That's why it's crashing in some parts. So the options are to use the version of gapps as mentioned by tomi_cc16.

Maybe someone will compile a more recent webview for Tegra 2...

ART on Android 7.0

I've noticed several mentions on the web of Android 7.0 changing the way ART works. Here's one of them:

Android 7.0 switches things up a little, re-introducing just-in-time (JIT) compilation to ART’s repertoire. In simple terms, this means the Android system will pre-compile some apps but only compile parts of other apps when they are actually required. The result is a faster booting phone, apps that use less RAM, require less storage and get updated faster. Not bad, huh?​

Like most people, I did not exactly enjoy waiting while my Tab "optimized" 90+ applications. Having applications launch more quickly seemed a trade-off that each person could pick from. Wait a long time once vs. wait a short time EVERY time. It seems like 7.0 is supposed to be "the best of both worlds". No up-front optimizing delay, but continuous optimizing during idle periods. But..... is that what is happening?

With Android 6.0, there was a line in build.prop that directed use of JIT or ART, by changing a parameter from "Quick" to "Optimizing". The build.prop that came with this newest AOSP has this:

line 72: dalvik.vm.image-dex2oat-flags=-compiler-backend=Quick

line 73: dalvikvm.dex2oat-flags=-compiler-backend=Quick​

Sounds like we're telling 7.0 "don't optimize." After quite some time scouring Developer web pages, I have not found a clear explanation of this option, or why there are two lines instead of one. Is Quick the only option? Or, there are other options but they are worse? If there's a short explanation, I'd like to hear it (or a link to somewhere in the developer information).
[Galaxy Tab 10.1 Android Development] decatf:
Android is still pre-compiling apps in Nougat. It is not compiling everything as it did previously. That takes a very long time. Now it takes less time but it still takes time. We are not disabling any optimization. If you disable all pre-compilation and run in pure JIT mode then this is the least optimized.

Quick and Optimizing are the only two compilers. The image property (line 72) is for core system frameworks. The other is for everything else. I don't know why it split into two options. These options are set because Optimizing does not support Tegra 2 (NEON operations). I've fixed ART for this ROM to support this CPU. The options are set anyways so things don't break when people install Xposed which replaces ART with its own version.

Build 20161012

Changes

Update system webview

Fix Setup Wizard Play Services crash

Fix SuperSU installation

Partially working camera video recording

- 720p recording not working

Advanced reboot menu

P3 PowerHAL save cpufreq max on init

Enable nvmap carveout killer / misc GPU memory management

Rework display suspend/resume sequence

SD video recording is working. HD video is not working. The camera blobs are still behaving strangely so things will probably be buggy.

Overclocking, voltage control, voodoo sound, whatever other sysfs configs might be working better with SuperSU than phh Superuser. Access is getting blocked due to super user or SELinux despite being allowed in the sepolicy. It's not clear what the deal is with that. If it's still not working then set SELinux to enforcing.
[Galaxy Tab 10.1 Android Development] dihoc:
So far everything has worked except the stock browser. It freezes every single time. I use Firefox instead. Does anybody have the same problem?
[Galaxy Tab 10.1 Android Development] UncleDick:
Does this mean the current stable release of SuperSU, (2.78) or the 2.51 that we have been installing?

(This may be obvious, but I have rebuilt from scratch so many times that I now ask before flashing things.)

Thanks

Hi everyone, I would like to find out it this new update (aosp-7.0-p4-20161012.zip) for my p4 (GT-P7500) version is working with a SIM yet?

Yeap, every time you want to power off this device without chance to experience the bug.
[Galaxy Tab 10.1 Android Development] SirVss:
Huh, this is inconvenient, at least ! And there is no fix for this bug yet ?

Thanks !
[Galaxy Tab 10.1 Android Development] decatf:
There's no fix and there may never be. The bug has always existed but for some reason Android N is causing to occur frequently rather than rarely.

The bug is that the power regulators fail to shut down. Samsungs "fix" was to spin in an infinite loop doing the shutdown procedure until the hardware reports that it is powered off. It used to be rare that it would never power off. Now it occurs often.

So what solutions are there? The hardware won't power off and all the software can do is try again or skip it and do nothing. Either way it drains the battery. We only know that it's rare in older software like recovery or older ROMs. So the only way for now is to work around it by doing power off from recovery.

20170807 not working on p4

Hello,

I am stuck with the boot animation with the latest "20170807" build as well.

This is the device I have and have downloaded the image for: (p4 / GT-P7500) ... and I can confirm the previous build works fine for me.

I've originally tried to upgrade from the old release simply by installing this image over the previous one but that didn't work. Then I have slowly got to the state where I deleted everything on my tablet and tried to clean install this release, with no gapps and no root. But nothing I did helped me get this working.
[Galaxy Tab 10.1 Android Development] Technical:

[Galaxy Tab 10.1 Android Development] jaibar:
Thanks for new August build!

I tried using Magisk 13.3 but get "install error 1". Any ideas?

A minor thing: when rebooting to recovery from power menu, the temporary window says "factory data reset" (instead of reboot to recovery) ?
[Galaxy Tab 10.1 Android Development] frov:
Well, I did that same reboot and for me the effect was indeed 'Factory Default': the SD card content was gone when I got into TWRP (the 3.0 one from the same Dev).

BTW, I have now played around this evening with this ROM on this Tab 10.1 (GT-P7500): it runs OK. The Tab10 is not a powerhouse (compared to eg my N9 on N10) but it is OK-ish.

Also: when I first booted it this morning I did not get the keyboard to pop-up (so eg I could not enter wifi pw). I ended up copying another keyboard apk (Xperia KB in this case) and installed that via Settings --> Storage --> Explore. That also did not work imm, as Android asked for some KB config. After some fiddling it finally worked and I could add wifi and an account.

The camera does not work that perfectly either, but eh, do we really want to take pics with this tablet? OpenCamera I removed again. The old Google Camera does work (same as the AOSP one).

I also installed SuperSU and then AdAway: all works nice. All other root tools I normally use, like TotalCommander and Kernel Adiutor, all work OK.

As for Browser: both Chrome and Firefox do not really work that nice on this tablet/ROM; I saw someone hint here for for a Lightning Browser and that indeed works OK.

So, all in all, I think I kicked my friends Galaxy Tab 10.1 into Nougat and am ready with that; I expect she will be rather pleased with it. Thanks to all here [MENTION=243864]xda[/MENTION] !

Edit2: I now see in the OP that there is also Overclock and ZRAM: did not look for or fiddle with that yet (via Kernel Adiutor): something I will try t'row.

---------- Post added 13th August 2017 at 12:21 AM ---------- Previous post was 12th August 2017 at 11:52 PM ----------

Q: just read about the TRIM kernel in a thread nearby by the same Dev: is TRIM included in this ROM/kernel ? Or should I attempt and install that TRIM kernel over this August Nougat ROM? Thanks!

twrp -> flash hangs

after (mostly not) using the p4wifi with cwm 6.0.3.6 and cm 10.1 because of the open security issues

I installed twrp 3.0.3 -> works

and tried installing aosp-7.1-p4wifi-20170118.zip and later aosp-7.1-p4wifi-20170506.zip through

adb sideload aosp-7.1-p4wifi-20170118.zip -> repeatedly hangs at 44%

and after that through

adb push aosp-7.1-p4wifi-20170118.zip /sdcard/ or adb push aosp-7.1-p4wifi-20170506.zip /sdcard/

followed by boot into recovery / swipe to allow modification / install / pick file {one of the named above} / swipe to confirm flash. The flashing process starts but never finishes.

Picture can be found at fs5.directupload.net images 170813 gczgzu2a.jpg - sorry, am not allowed to use links.

I'm not really into the tech details of flashing new roms/rom and fs layouts/... but the Target string shown during the flash process seems strange to me

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

Could need some help to get things working.

I was not lucky with twrp 3.0.3. I used twrp 3.0.0 to successfully flashed aosp 7.1.2 20170811 (both clean and dirty). The only thing I had to do was reflashing phhsuperuser to get root.
[Galaxy Tab 10.1 Android Development] UncleDick:
Dirty Flash OK, too.

I did my usual dirty flash:

Download files

Restart to Recovery (TWRP 3.0.2)

Do TWRP backup and erase previous backup

Wipe only Cache, Dalvik, System (not wipe Data)

Flash aosp-7.1-p4wifi-20170811, P7500-open_gapps-arm-7.1-pico-20170416, supersu 2.82.

Restart

Download and install decatf-chromium-60-20170802.apk

Use Build.Prop Editor to change "Quick" to "Optimizing"

Use Kernal Adiutor to change CPU speed to 1400

Restart to Recovery

Wipe Cache, Dalvik

Restart

My apps that were not wiped seem to function OK. New Chromium works. I also noted when restarting to Recovery the message "factory data reset" pops up for a second., but it obviously didn't mean it.

Great work, decatf !

"Use Build.Prop Editor to change "Quick" to "Optimizing" - Can't fond this setting in Build.Prop, do I need to add it, and if so where, please?
[Galaxy Tab 10.1 Android Development] UncleDick:
Short answer: No, you don't need this.

Long answer: The configuration file

build.prop

(for "properties") gives instructions and options needed to correctly compile the system and programs. Among the hundreds of options is a choice of whether to to a "Quick" compile or an "Optimized" compile. The default is Quick. These two lines in build.prop indicate which choice to use:

dalvik.vm.imae-dex2oat-flags=-compi8ler-backend=Quick

dalvik.vm.dex2oat-flags=-compiler-backend=Quick​

There are many articles on the web explaining how Quick differs from Optimizing. For most people, Quick (the default) is fine. Honestly, I am not sure that Optimizing makes the tablet run any faster. If there is a difference, it seems to be small. It's just one of those things that I do "because it's there."

This was probably more than you wanted to know. If you are interested, I would read up a little before doing it.

There are lots of Apps that can edit the build.prop file. I happen to use BuildProp Editor by JRummy Apps.
