GT-P7501

Can i use this ROM with GT-P7501 too?
[Galaxy Tab 10.1 Android Development] bierma32:
[/COLOR]

Yes you can.

The GT-P 7501 is the German Version of the - P7500.

Both are the same only the Cover is little bit different.
[Galaxy Tab 10.1 Android Development] mad-murdock:
So I flashed just the ROM as instructed in OP, no root, no gapps (so far).

I seem to be stuck in a bootloop - seeing the animated "android" logo animating for ages without getting done. I waited about 20 minutes before giving up.

Any idea what might have gone wrong?

Hi [MENTION=4404851]decatf[/MENTION],

how do you emulate NEON instructons? Do you do it in the illegal instruction handler in the kernel?

Do you emulate all the instructions? This is the logcat trace:

I have some Unity3D apps which fails to load, could it be due to missing instructions?

Instructions how to download AOSP & Decatf repo source for AOSP 8.1.0_r42

I made instructions on how to download both AOSP 8.1.0_r42 and Decatf's repo 8.1 branches. It required reworking manifest repo a little. It looks like Decatf is missing "android_hardware_interfaces" repo that he referenced in local_manifest.xml but is nowhere to be found on his github. If anyone can help me find it, we'd all be grateful.

Instructions are in the fork's readme: https://github.com/allhavebrainimplantsandmore/manifest/tree/aosp-8.1-dev

Is there a working GApp for this rom?

Is there a working GApp for this rom? I've tried 8.1 pico version of the Open Gapp and it keeps stopping. Any working GApp version? Can anyone point to it?
[Galaxy Tab 10.1 Android Development] bierma32:
If try opengapps you need to download pico vor nano Version.

But the best performance is without gapps try pure apk vor other.
[Galaxy Tab 10.1 Android Development] bricked73h:
[MENTION=5390857]bierma32[/MENTION]

Hello bierma32, thanks for the response.

of course the best performance could be without GApps, but there are reasons why people need GApps.

and as I have mentioned in my question above

I've tried 8.1 pico version of the Open Gapp and it keeps stopping.

I actually could not login to Google account to access the Play store.

have you had any success in using Open GApp without the Google play service stopping with this rom?
[Galaxy Tab 10.1 Android Development] bierma32:
I think Google play store and G play service Form today are to New for old Tab , you can try an oder Version from release date oft decatf s Rom. If this working you have to diasable the auto update .

It was the same on AOSP 7.x

[Galaxy Tab 10.1 Android Development] Roggenstubs:
Thanks a lot to decatf for this ROM that helped me bringing my old tablet back to live.

The update (TWRP, AOSP, GApps) worked fine.

I have Galaxy Tab 10.1n (GT-P7501) with keyboard dock and USB connection kit.

I could also revive the keyboard by installing sec_keyboard as described here:

sec_keyboard download link and description

Different to adding this driver to Android 5 AOSP I now had to patch sec_keyboard file to run with Android 7.

See here: Position Independent Executables and Android

I am using SManager app to run the script. I just have to remember to always connect the keyboard

after

the script has been executed.

EKH helps me configuring the correct keyboard layout.

I didn't succeed using USB OTG with USB stick or SDCard.

It runs fine from within TWRP but not from AOSP.

This problem is known as can be seen here (post from decatf).

I also wanted to install chromium for this non-NEON chipset but the download link is broken.

I didn't give the Android 8 AOSP a try yet because I have read that this Android 7 AOSP would work better and smoother (and with camera support).

I don't know yet, if I will keep on using this Tab with Android 7. It works, but it is slow and many apps do not work anymore because of missing NEON within Tegra2 ...

[Galaxy Tab 10.1 Android Development] LR7875:
The 3G is a bug and will not work. However, P4 devices can flash the p4wifi zip.

Also flash the TWRP bigsys provided, and reboot recovery, before flashing ROM.

I did the update on my old Samsung Galaxy Tab GT-P7500 and Android 8.1 works. Thank you a lot. Unfortunately the system is not very fast. So I installed "Magisk-v20.4.zip" on the tablet to get it rootet. The App SuperSu tells me that the tablet is rooted. But if I start "SetCPU" to overclock the tablet - this does not work (""root access not granted").

Is there another way to overclock?

Why you install magisk and than the Supersu.apk ?

Normal way install magisk and than magisk manager and from magisk manager you can give setcpu or Kernel Auditor the Root rights.View attachment 5447853

the latest 8.1 of open gapps seems to cause it not too even boot up correctly from there website for this tablet.

I tried the following aosp-8.1-p4wifi-20181011.zip with open_gapps-arm-8.1-pico-20220215.zip on a clean install of twrp311-20180416-BIGSYS.zip

upon rebooting into this android 8.1 it shows the android logo for a very long time then it reboots back into twrp, so did I go about it wrong, should I first install android aosp first reboot then go back into twrp to install the open gapps, since I want to know why trying to update them would cause it to fail to start the OS on my old samsung galaxy tab, I can go back to a older version of android on this device, but was wondering if anyone has any idea's what the problem might be, if anyone online that still uses this tablet, I have been working on trying 4.4.4 , 5.1 and 6.0 and even going to try 7.1. I don't recall since its been so long which android version works best on this old tablet, my newer tablet I have it running android 11, I tried android 12 on my newer samsung but it was having battery drain problems so I went back to version 11 on it. I don't think this old tablet can handle android 9 or above. since when I tried android 8 something on it before it didn't respond as well to the touch menus, the older android versions worked better I think but this tablet doesn't have much support anymore it seems compared to my newer one, but I wanted to get it working the best it came for while it still charges and works.

It is one ROM and recovery for p4wifi (GT-P7510), p4 (GT-P7500), and p4tmo (SGH-T859) since 3G/cellular will not work in the kernel. There is no difference between the two devices other than the cellular modem.

I wonder if it is possible to install AOSP-8 without a special TWRP, and instead use multirom TWRP 3.0.2.0.

It won't work as a primary system, but as a child system it might work.

I can't test this method because I only have a p7500.

TWRP bigsys use a hidden partion to extend the system size. That works only with aosp 8

1st start into TWRP BIGSYS recovery never got around scrolling screen issue. So will need to re-install old TWRP and try to find out why it loops...

-- EDIT --

This was with latest and greatest 20171107 image. Will try 20171106 version. Could be eMMC issue...

-- EDIT --

The 20171106 version (file named p4wifi_twrp311-20171101-BIGSYS.zip) has same rolling screen issue... I went back to the 'normal' 3.1.1-20171009 version of TWRP without any issue. Odin3 is my best friend! That recovery does not show the scrolling screen issue.

As you removed the new related Kernel thread, and I remember that this tablet (I have 2 different 7510's) does have the specific type you were looking for then, I am not sure what info you would like to have regarding the scrolling screen issue for the BIGSYS TWRP...

Your tab has the other display panel type I was looking for people to test. There is some more mechanisms in the kernel which I didn't know about. I need to study it some more to figure out what parts are not right.

The best we can do is trial and error at the moment . To test it you will install TWRP BigSys and see if the display works. Otherwise go back to which ever previous version you're using. There is nothing to do for now though because I haven't figured out what's not working right.

Alas, again no joy... Both show the same scrolling issue. But I am still game... Send more my way, I can take 'em.

P.S. Because of the scrolling I am not able to see much difference in scrolling behaviour, but it seems the last two have less 'banding blocks' in the scrolling, i.e. more full white/blue, instead of bands of scrolling parts on screen, if that helps you.
[Galaxy Tab 10.1 Android Development] decatf:
Get the kernel log from recovery (TEST_D) using ADB.

adb shell dmesg > dmesg.log

It should configured the way I expect it to be. I can run the code path for each display panel type on my own device but of course only one will work for me. Unless there is something weird at runtime on the actual hardware that is causing it to be configured right.

The problem is that the display panels have zero tolerances so the configuration must be 100% precise down to the clock rate in Hz. Otherwise we get the rolling screen. The visual behavior doesn't tell much.

If you can get the kernel log from the BigSys recovery then after that try this AOSP 7.1 test ROM that I originally posted in this thread. There is not much else to try for the recovery stuff. Install the most recent version of aosp-7.1.2 then install this testing ROM over it. Boot the test ROM and see if the display works right.

androidfilehost.com/?fid=745849072291687067

If not then get the output from this command

cat /sys/kernel/debug/clk/clk_summary
[Galaxy Tab 10.1 Android Development] Just_Another_N00b:
Willdo. Have to set up a stand-alone adb-env first, so will take a little bit. Stay tuned...

Here is the dmesg.log while in ]scrolling] recovery version D...

-- EDIT --

With twrp311-20171009-p4wifi and aosp-7.1-p4wifi-20171005.zip installed, overlaying (dirty flash) now with your TESTING version with the new kernel of aosp-7.1-p4wifi-20171014-TESTING.zip... Stay tuned...

-- EDIT --

The 20171014 TESTING version also has the same scrolling issue. Even the Samsung 10.1 Pre-Boot Image goes off whack (shift left, almost off-screen) before the scroll starts of the "Android" text boot-up image. Wondering if you would be helped with a dmesg.log on that boot-up, or not... Otherwise I will just stay on the old kernel version of 7.1.2. I can remember that originally this tablet also had the infamous scrolling issue when rooting of the 75x0 started out way back when with CWM...

Will get you the clk_summary output of the non-TESTING version 7.1.2, unless you would like that from the TESTING version...

-- EDIT --

Ok, the clk_summary does not exist on the non-TESTING version, so I will reflash with the TESTING version and try to get it from there...
[Galaxy Tab 10.1 Android Development] decatf:
You don't need to keep switching between the aosp-7.1.2 ROMs. Just stick with the 20171014-TESTING. That ROM is compatible with kernel 3.1 and 3.18.

The clk_summary is only for the new kernels (3.18/4.4). For the old 3.1 kernel it is located at /sys/kernel/debug/clock/clock_tree.

Can you also get the output of the display mode. This should be the same path on all kernels.

cat /sys/devices/tegradc.0/mode

So from the 3.1 kernel get the outputs of:

cat /sys/kernel/debug/clock/clock_tree
cat /sys/devices/tegradc.0/mode

From 3.18

cat /sys/kernel/debug/clk/clk_summary
cat /sys/devices/tegradc.0/mode

You can try this 3.18 kernel. I've also uploaded a standalone of the 3.1 kernel so you can switch back easily.

p4wifi-kernel-3.18-20171108.zip

p4wifi-kernel-3.1-20171108.zip
[Galaxy Tab 10.1 Android Development] Just_Another_N00b:
Using the 3.18 kernel (TESTING ROM) via ADB I have retrieved and attached the clk_summary and mode files... Do you also need this from the 3.1 kernel?

Booting from a 3.1 kernel flash works wonderfully fast...

Question: When flashing kernel-only do I still need to clear cache?

-- EDIT --

Adding the 3.1 kernel clock_tree and display_mode files
[Galaxy Tab 10.1 Android Development] decatf:
No.

Did you try the 3.18 kernel I posted above? If that doesn't work then get the outputs from clk_summary and mode from that kernel. Also get the kernel log too.
