in answer to the replies

- i did'nt find anything like twrp 3.0.0. twrp 3.0.2 seems to be the way to go.

anyway the device went into repair nearly immediately after hand out to me. did not start, just plain black screen. got it pack repaired back then.

I adb pushed different versions of aosp for further trials to /sdcard/ and turned it of two days ago.

after that it didn't start again. black screen as years ago, two times got a not rotating charging symbol after plugin in.

-> if someone needs a p7510 google io edition in pretty well visual shape with box (+battery seemed to be still pretty good last time i used it) as spare part she/he can contact me (berlin, ger).

thanks for your help anyway

Hello,

I am using this ROM and it's very nice, but not beeing able to play 720p Youtube video for my child made me think going back to ICS 4.0.4, official ROM.

Can I do this? Is there anything I should know and do before this downgrade?

Thanks!
[Galaxy Tab 10.1 Android Development] olimar7184:
You play 720p on ics ?

Sorry but on this ROM I think there is no way to play higher resolution on streaming than 480p without lag/freeze. I think it's because the streaming itself need resources to handle m.

But on vlc with a downloaded video it works on 720p.

Latest Google Play Services 11.3.02 now working??

I just flashed the latest ROM and it's working great for me. Least lag ever maybe (not sure why).

But the big surprise was the latest Google Play services 11.3.02 is not causing errors! I didn't see anyone mention this yet - have I been under a rock? Crossing fingers the errors don't start when I update some google thing or another.

The only other problem for me is with Google Maps (9.44.3 last recommended working version).

The map field goes black/blank sometimes (as someone mentioned a few pages back).

I tried clearing the app's cache and data and that worked so far but I haven't tested it yet. Has anyone totally solved this?

Thanks again to decatf for this update for the 6th birthday of my tablet :D

I used this process a few days ago to get this image working on my Galaxy Tab 10.1. It was odd, I had used this ROM about three months ago, but then tried to upgrade and for some reason the image would not apply for over a month no matter how much I tried (went back to full stock). Then I tried again down the road (maybe the TWRP change? Don't know) and everything went fine. Thanks to the OP for keeping this alive. Chromium build also works pretty good too.
[Galaxy Tab 10.1 Android Development] rubbercorners:
I don't know if it sheds any light but I've always used TWRP 2.8.7.0 for flashing Nougat (and previous) versions of this ROM (for p4wifi) and never had a problem.

Are there any disadvantages to using this older version?
[Galaxy Tab 10.1 Android Development] decatf:
None. If it flashes ROMs and everything works for you then there is no difference.

The newer recoveries have some features or bug fixes which I can't remember all of them but if everything is working for you then there's no advantages.

OEM from samfirmware.com
[Galaxy Tab 10.1 Android Development] Just_Another_N00b:
Sammobile.com (a redirect from your link, by the way) supplies instructions for flashing the original rom onto your tablet (by using odin3), so you can downgrade to the factory-rom (version 4.0.4) by downloading the image, odin3 and follow the instructions. This information has been mentioned a few times in this thread, but it does require some actions on your part, by going through the thread or searching within the thread to find it...

Good luck on the factory-restore (if that is what you mean with OEM rom load)...

phhsuperuser?

You may be "SOL" with regard to phhsuperuser. I can verify that SuperSU 2.82 flashes and works correctly on aosp-7.1-p4wifi-20170914.zip (I have only the WiFi model.)

Since decatf uploaded a version of Magisk 14.0 (https://xdaforums.com/devdb/project/dl/?id=26675), that is clearly another choice. If SuperSU ever fails to load, I plan to move to Magisk.

Good Luck!

Hi !

I got a Question...

I read that this ROM contains a NEON Emulator but somehow it doesnt look like it.

Almost every game i try to install results in that infamous "Failure to initialize" message.

AIDA64 also says "No NEON support".

I understood it that NEON EMulator is enabled by default and i could use a setrpotp to DISABLE it (which i dont want).

I am aware that it might be very slow IF it is eneabled but it seems to be disabled, can someone help me ?

Greetings,

Ender
[Galaxy Tab 10.1 Android Development] decatf:
Change the video recording setting to low quality.

AIDA64 displays hardware capabilities. Emulation is only software. There is no NEON hardware. Those games don't work because they detect that there is no real NEON hardware just like AIDA64.
[Galaxy Tab 10.1 Android Development] enderffx:
Hi decatf, i feared that answer :)

Thank you for giving it anyways and a hell lot of more thanks for that ROM of course.

Same here: Magisk 14 does not find the boot partition and therefore quits the installation - version 13.3 does find the boot part. and can install - later I can update to 14 via the app when I manually select the correct partition /dev/block/mmcblk0p3 ... :confused:

Will post a comment into the Magisk forum thread to see if this can be fixed in version 15. :fingers-crossed:

Magisk patch

superusersu boot img patch will not work on p4wifi.

Magisk works just fine if you make it find the boot partition.

Although SuperSU app isn't very responsive when you start it after installing the p4wifi-patched Magisk version, it will gladly prompt you for granting/denying access to apps.

I just hardcoded the boot image device in find_boot_image() function (too lazy to programmatically grep for it in the recovery fstab) and this Magisk version probably works ONLY with p4wifi device.

https: // xoroid.com/Magisk-v14.0p1-p4wifi.zip

[Galaxy Tab 10.1 Android Development] decatf:
The current version of Play Services uses NEON again. For some months Play Services did not have NEON but the recent update uses it again. It also exposes some bug in NEON emulation which is why it's crashing.

There is also another bug that causes app crashes which is due to sqlite in this ROM which I had been updating from upstream. That can be fixed by going back to the stock Android sqlite.

The NEON emulation bug will take some work to figure out.
[Galaxy Tab 10.1 Android Development] rubbercorners:
Ahh I see. But I assume if I go back to the 10.5.42beta Play Services it will work for now...

Can anyone tell me how to do this since I've already rolled back to 10.5.48 (that came with pico-20170416 gapps) and it doesn't work?

Is the only way to reflash the ROM and flash the earlier gapps pico-20170119 ?

Skype is no go

I am very surprised with the speed of this rom!

Got it installed and I have to say: Well done!

This has been an ordeal for me.

The task was to fix grandma's tablet (p4wifi==P7510) which is not

working since ~February. And somehow I got on a wrong track trying

couple of old backups I had on my hard drive. Only after a day I

realized Tegra2 issue :(

However Google Drive and Skype are must!

While Google Drive can probably be solved by finding some older version (which?), Skype is a no go.

Whatever version of Skype I try there is always green screen from front camera.

Pretty please did anybody solve:

- Google Drive that works?

- Skype with working front camera?

But I am guessing that Skype is not solvable...

My only alternative now is to try to install AOSP Android 5.1.1

Lollipop by decatf, as the vague description seems to indicate that

video is fully working? And then try to get app versions without

Tegra2 issue?

Hmmm, This Android 7.1.2 Nougat has Google Play services 10.5.48,

so I would probably need same 10.5.48 but for lower android (apkmirror).

Build 20171005

- Fixes a bug causing NEON emulation to crash.

- libsqlite is back to the stock AOSP version which fixes some app crashes.

Google is not doing security updates anymore for android-7.1.2. This will probably be the last build of this ROM.
[Galaxy Tab 10.1 Android Development] Smiff3:
thanks a lot for this, got it installed, on first boot play services stopped working. i had problems with this before on your 5.1, can anyone confirm please how to install and make sure play services keeps working? the recommended version in first post is lower than the one that came with the gapps package on first post.. can i just install the gms apk.. is it possible to stop gms updates like any other app? i don't think so? thanks.

edit:

btw for anyone on linux, the heimdall instructions for TWRP which i couldn't find anywhere are:

sudo heimdall flash --SOS recovery.img --no-reboot
sudo heimdall flash --HID hidden.img --no-reboot

the tablet seems to lock up after each step so force power off and keep going.

CWM doesnt work for this rom!

for root, you must rememember after flashing the superuser.zip to go to play store and install the correct superuser, those are steps 1 AND 2, not 1 or 2, oops!

thanks hope this helps someone.

play services included in linked gapps pico is 10.5.48 - this is too new?

edit: weirdly google play services updated itself to 11.5.18 and seems to be fine. not sure what to make of this.. neon emulation? ignore? roll back?

2nd, bit confused why supersu installer is bundled (there's a prompt to update on first boot, which fails), but supersu isn't compatible? edit: just freeze it with link2sd and ignore seems fine.
[Galaxy Tab 10.1 Android Development] decatf:
SuperSU is bundled with some versions of TWRP. That has nothing to do with any ROM. The SuperSU bundled recovery was a mistake anyways since it's not even compatible with all ROMs as you have discovered. Don't install that SuperSU and it won't ask again unless you wipe or install a different ROM.

Hi bierma32,

Thanks for your reply.

Then throw TWRP I flashed aosp-7.1-p4-20171005 which I had download earlier on device memory.

Did I do something wrong in this steps?

Is there a link with an steps I' missing?

Thank you.
[Galaxy Tab 10.1 Android Development] bierma32:
I think the old int. SDcard from Stock is also on your Tab and not wiped. ( 4.1.2 version roms use the /data/media directory as the "internal sdcard")

If you boot into TWRP / advanced / file manager you can select the folders und delete.

From 4.2+ versions of Android use the /data/media/0 directory due to support for multiple users.

Have you got a OTG USB adapter ?
[Galaxy Tab 10.1 Android Development] Thrakhath:
