Hi I selected all tweaks.

Hi anybody got MTP working, I can't transfer any data to the tablet because MTP doens't work for me, even if I selectet it in developer options, when I plug into my PC Tablet only charges.

https://www.youtube.com/watch?v=kpQWq6k-g0M

Here I made a small video about the HD Youtube performance (720p). Can't test with 1080p coz it's not selectable in Youtube app :/
[Galaxy Tab 10.1 Android Development] OlMightyG:
Seems good mate, why would you want to play 1080p videos on a 720p device if there are 720p videos available?

Connect usb, tap the notification shown in the notifications area. Select mtp.

I just brought my 10.1 back from the dead and found it is running Cyanogen on Android 4.2.2

Do you think the upgrade is worth it? Will I see improved performance with Android 6.0?

Awesome work anyways, thank you
[Galaxy Tab 10.1 Android Development] OlMightyG:
I had 4.3 (SlimSaber) and 4.4 (Omni) on it. Both were not as good as this one. Check this thread to see the few issues and decide if they are relevant for you. Perfurmace and battery is insanely good.
[Galaxy Tab 10.1 Android Development] DrWoodStein:
Agree 100% If you are ok with the issues listed, flash it. This rom is the business. Then do the speed tweaks in this thread.

Superb!

Further playing: add xposed with gravity box and play!
[Galaxy Tab 10.1 Android Development] longjohn41:
Ive tried this and although the eposed installer framework installed I can't get GravityBox to run, although it's enabled in exposed (followed by reboot).

de.robv.android.xposed.installer_v32_de4f0d.apk

xposed-v83-sdk23-arm

GravityBox system framework won't respond with either;

GravityBox_3.6.1,.apk

or,

com.ceco.marshmallow.gravitybox_v613_6543b5.apk

Edit: xposed-v83-sdk23-arm installed via TWRP, but xposed installer says xposed not yet compatible with SDK v23 or armeabi-v7a.
[Galaxy Tab 10.1 Android Development] DrWoodStein:
I am using version 80 for sdk 23

Using Installer version 3.0 Alpha4

Marshmallow GravityBox v6.1.1

from here: http://xdaforums.com/showthread.php?t=3034811

Hope this helps...
[Galaxy Tab 10.1 Android Development] longjohn41:
Thanks for that. I uninstalled the installer and installed the alpha and it's now working. I think I probably installed an earlier version while half asleep in the early hours of the morning. :)

The 20160428 ROM fixes headphone detection.

Chrome 50 is compiled with NEON so disable auto-update in Play Store to stick with the older versions. I added a link to Chrome 49.0 in the first post.

hey great Rom especially with the headphone fix thank you man
[Galaxy Tab 10.1 Android Development] longjohn41:

I try this rom yesterday, I did clean system data and cache, but I cant install anything from playstore. there is notification that I need to sign in to authorize. then I tried to remove my google account, clear data, clear cache both playstore app and playstore service, allow all permission, check the android device manager in device administrator, wipe the cache from TWRP.

But error msg "google play service has stopped" keeps pop ups everytime I open google playstore.

the 2nd is I cant make a phone call. theres "com.android.phone has stopped" error popup everytime I try make a phone call. but Data Network is working.

any help?

update :

- full wipe (cache, data, system, internal) and reinstall seems solved "google framework has stopped" problem. (im using g apps pico now.)

but I still cant make phone call send sms, cant receive phone call & sms too.

3. GPS cant lock. I install G Maps and Waze, waze popup "service error" after loading for a minute then close the app itself. Maps able to load and download with mobile data, but cannot lock to my location. I already check the permission setting for those apps, and gave them full permission.

4. cannot receive file from bluetooth. I tried sending files from android phone and pc, no luck. but my tab can send files to both devices. I dont know whats wrong.

i hope gps and bluetooth can work, i used them pretty often.

New 0428 Rom

Hi,

I install this new rom with pico open gaps and until now I found no problems.

Thank you very much, keep on the good work. :):good:

---------- Post added at 12:26 PM ---------- Previous post was at 12:22 PM ----------

I install the new rom with TWRP but an old version, 2.7.8. Can someone tell wich is the last version where I can find it?

One problem I downlod the nano version from open gaps but it fail to install with the rom using TWRP.

Thanks
[Galaxy Tab 10.1 Android Development] OlMightyG:
- Check gps.conf in /etc. See several guides how to do this. It should be something like this (not exactly this). Dont trust guides that tell you to add more lines than that:

NTP_SERVER=0.at.pool.ntp.org
XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin
XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin
XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin
SUPL_HOST=supl.nokia.com
SUPL_PORT=7275

The NTP Server should be a correct one from your region.

- Try removing nv_data.bin and nv_data.bak from the /efs folder via filemanager (you will need root). Backup them first. The files are generated again automatically. Dont touch anything else in this folder. No guarantee that this fixes your problem. But it did for me and some others after changing Android versions.

Hello,

TRIM support: built-in? Or just use the Apr 14 .zip?

Changelog doesn't say that TRIM support it now built-in;

before, OS update had corresponding TRIM update.

Please clarify; and thank you for your continuing updates!
[Galaxy Tab 10.1 Android Development] decatf:
There's no changes in the kernel since Apr 14. So just keep using that one.

NEON strikes again???

The Chrome 49 notice was perfect, decatf. Unfortunately, the gmail app was just updated and now it FCs but the background notifications still work.

Is NEON going to eventually work its way into all gapps and leave us hurting? Is this even NEON that's killing gmail?

Thanks again
[Galaxy Tab 10.1 Android Development] decatf:
Yes, NEON is the minimum spec now.

I don't know if Google announced it or documented it officially but the writing is on the wall. GApps, Google apps, and the Android source are all having NEON features creeping in.
[Galaxy Tab 10.1 Android Development] UncleDick:
My April 26 GMail seems to work OK. (6.4.120760496)

InBox by GMail just updated today (May 5).

Can you clarify which is now failing?
[Galaxy Tab 10.1 Android Development] OlMightyG:
And there is no way to get them working on the old devices?
[Galaxy Tab 10.1 Android Development] decatf:
No way.
[Galaxy Tab 10.1 Android Development] sflesch:
So are these updates specific to 6 or do we need to worry about 5 too?

Is it just a matter of disabling updates for each app?
[Galaxy Tab 10.1 Android Development] decatf:
It's ROM independent. NEON is a hardware feature.

Disables updates, use old versions, use alternative apps. Anything that isn't compiled for NEON CPUs.
[Galaxy Tab 10.1 Android Development] OlMightyG:
No possibility to "emulate" this?

Ok, I am only using Playstore and Youtube (from Google) on this old device. Are this apps are going to be affected?
[Galaxy Tab 10.1 Android Development] decatf:
Theoretically it can be emulated but no such thing exists. It's up to the app developer to provide legacy support.
[Galaxy Tab 10.1 Android Development] DrGirlfriend:
I'm back with your same version working, here's why. After gmail force closed forever, ES File Explorer began FCs. Then on reboot I got "Unfortunately, android has stopped working". This is bad.

I wiped /system /data /cache-dalvic and reflashed aosp6.0 428, pico gapps 429, trim kernel 414 and superSu and all is good. More testing needed as to how I got there in the first place. I usually use Kernel Adiutor (12000 or 14000) but suspect that might be what's hosing my setup.

Sorry to raise the NEON alarm, it's not in this release and probably never will be in gmail. NEON makes sense when SIMD piplineing math is needed, not an email client.

Which brings us back to chrome 50, now with NEON! Where can we find real Google release notes for a build such as NEON dependency and so on?

Meanwhile auto-update diabled for all of playstore apps.

(sort of rings a bell) can't install 6.0 directly

me again.. difficulty flashing the 6.0 ROM

if I install the 5.1.1 ROM first, then flash 6.0 withOUT

wiping system, 6.0 flashes

if i wipe system (as per OP instructions, along with /cache, /data, /dalvik)

then same error

this scenario seems vaguely familiar..

but could have been a different device..

any one remember?

---------- Post added at 01:10 PM ---------- Previous post was at 12:33 PM ----------

argh.. simple solution =p

in Mounts, system was mounted.. simply unmounted it,

and no issues. not sure why it was set to mount,

but in case, easy fix

not sure why the 5.1.1 ROM didn't care, but there it is =p

---

as to the install itself:

- flashed ROM

- flashed P4 kernel

- tried to flash slim 6.0 zero gapps - fail; flashed OpenGapps 6.0 nano (vs pico) dec 09; OK

- flashed supersu 2.52

took a while, but booted up to android;

google account / play store, seems to be working OK

[Galaxy Tab 10.1 Android Development] lilferraro:
Decatf, first let me start off by saying great job on the ROM. I didn't think it was going to be possible to bring marshmallow to this tab. Also, could you upload the latest source code on github because the latest source is for 5.1? When u have the chance of course....

I know its still early, but what are the fist impressions on 6.0 for our tab? 5.1.1 from decatf its just excelent all arround!
[Galaxy Tab 10.1 Android Development] AAccount:
Not sure if my advice is that helpful.

I remember video recording and general hardware video playback not working until a config flag in board_config_common along the lines of tf101 omx was added to the sources to enable a workaround for our hardware video decoder.

Along the lines of the art compiler not working, I remember trying to compile cm 12.1 for our tablet and got something similar. The logcat showed a "sigill" error for illegal instruction. My best guess is that it's optimizing for neon... which this tablet is a very sore loser for.

P7501 (10.1N, 3g) : MarshMellow Bootloop : use ODIN + older bootloader and recovery

Initial situation

Flashed Marshmellow but a kernel part was missing

Stuck at Galaxy Boot logo or "non charging" pictogram (but battery does charge a bit).

Recovery TWRP 2.8.7.0 not accessible.

Reflashing twrp2870-20150814-p4.tar.md5 did not work​

I managed to get all back on track using ODIN flash. You'll need

Odin3 v1.85

and the Odin flashable bootloader.tar.md5 and CWM 10.1 recovery you find here .​

I didn't use the modem, nor the older ROM.

Procedure

Step 1

On the PC, follow the standard procedure for using Odin (drivers, administrator rights, ...)

Launch Odin 1.85 as administrator

Plug the tablet in its charger (not the PC) for at least 30 minutes (mine did not indicate it was charging, but it did).​

Step 2

Enter in Odin mode (Power + Volume down), then twice Volume up to enter Odin Mode

Plug the tablet in the PC -- it should now show up in the Odin window ID:COM.​

Step 3

Select the bootloader.tar.md5 you've downloaded in the PDA field (WARNING : ONLY 3 checkboxes active : auto reboot, reset time and PDA)

Click Start

ODin should show success and the tablet should reboot.

Keep the Odin window on the PC open​

Step 4

repeat step 2 to enter in Odin Mode

Now select the recovery.tar.md5 you've downloaded in the PDA field

Click Start

ODin should show success and the tablet should reboot.​

Step 5

Enter in Odin mode (Power + Volume down), but now a second image should be present, left of the downloading image (see image).

Press left (Right puts you back in Odin mode, and this you don't want now)

Then press Power to select --> CWM 6.x.x.x opens​

You can now either use the .zip images that are still present on your tablet or use fastboot/adb sideload to install a new recovery or ROM.

I first upgraded to Lollipop (aosp-5.1.1-p4-20151031.zip image was still present) and its SuperSU. In Lollipop, I downloaded aosp-6.0-p4-20151211.zip.

Then upgraded again to TWRP 2.8.7.0 (using the CWM recovery and the TWRP zip file.

Finally, I used the aosp-6.0-p4-20151211.zip (not the first one that got me into trouble :o) and the BETA Super SU. ** GAPPS Nano Failed.

Running MashMellow with 3g working, camera working, ... most seems OK

Hope this helps someone to recover.
[Galaxy Tab 10.1 Android Development] decatf:
The tf101 omx workaround is not needed anymore. It's just a thing (libstagefrighthw.so) that loads the SOC specific OMX implementation. It's really simple. It's job is to load a blob and pass it off to the OS. So it turns out someone wrote one for tegra2/3 a long time ago. The bug with the proprietary one that we've had was one typo in a callback. The destructor callback had a typo leading to a null assignment. So every time some application closed the video system and the clean up happens it lead to a crash.

Also it looks like they've added some more debug logging in M and now it constantly spews some message about empty buffers. So that is some indication of one place where something is going wrong but we can't see inside the blobs so who knows what's going on. I've actually just commented out that log line since it seems the only real change is to check and log on some condition.

For ART I've tried to using "generic" instruction set but the exact same error happens. It seems there is a lot of work still going on with the Optimizing compiler so I'm holding out hope that maybe it will be fixed out of correctness/completeness of implementation. There is a tool to decompile the .oat files into assembly. I did that and tried to search for random NEON instructions but nothing did show up. The stack trace doesn't seem to point to any location in the disassembly so there is something weird going on there but I don't know what. So that's as far as I get could with that...

[Galaxy Tab 10.1 Android Development] decatf:
NEON is not strictly SIMD. There are some SISD operations too. If the vfpv3 is enabled during compile time then it's possible that there could be NEON operations generated. In the past it was standard to compile without NEON flags enabled so it wasn't something to that would affect this device.

[Galaxy Tab 10.1 Android Development] Mjoelnir77:
There are installation instruction in first post:

Further down the first post there are links. You will need to download twrp3000-20160207-p4wifi.zip and install that first (that is flashing it like the rom you wanted to flash) before flashing the rom.

Thanks in advance
[Galaxy Tab 10.1 Android Development] Mjoelnir77:
You are probably taking a too big package. Open Gapps come in different sizes - on the tab i take the pico package and that usually works. Everything else can then still be installed via playstore (but does not need system space then).
[Galaxy Tab 10.1 Android Development] nmaddy:
Yes you are correct. I did not take the pico version. Now I do not find a way to copy pico files to the tab.

tried 2 options

1. Connected tab to pc, pc finds the device but when I try to get into the folder to copy the files I am not able to. None of the folders show up. Throws error - Cannot copy item - Device has stopped or disconnected. The device is connected

2. Tries to download the file using browser but that's throwing an error.

Anyway of pushing the files into the tab?

Thanks

This is my first time installing a custom recovery, any ways to flash the ZIP without a pc?
[Galaxy Tab 10.1 Android Development] PowerDK:
You can boot into recovery mode. Connect the Tab to a PC and copy the files. I can also not get the Tab connected when booted on the ROM.

See also the tread with a new Trim kernel. I normally flash a kernel, ROM, pico Gapps and Super SU in one go in TWRP.
