Finally, I had time to check whether it's possible to build a 64bit firmware on the exynos7870. Yes, we have 64bit kernel, but all stock firmwares were 32bit, as result I need a lot of missed 64bit proprietary files.
This is fully 64bit firmware, missed files from a5'17 (it's on exynos7880) - gralloc, gps, ril, gles (mali).
Only own audio\camera still 32bit, but in any case it's working great in 64bit firmware.
I wrote own sensors HAL, because it's very specific for each device, it's still buggy, i'm continue work on it.
Right now I need understand - do we need 64bit at all? I don't see any huge improves.

new version.
now I can say - it's stable.
sensors - done (back to stock sensors.universal7870.so with prebuild 32bit service for sensors)
flip - done
it's still sometimes fc on camera - I'll check it later

I can confirm it works on SM-T580 (WiFi only) as well. Everything seems to work fine; buttons, WiFi + BT, camera, audio, video (youtube), sensors, smart cover etc.
OpenGApps 8.1 ARM64 installed with no errors.
The only thing I noticed is during first boot screen it says in the top-left corner in red text: 'Kernel is not seandroid enforcing'. Maybe this is on SM-T585 as well.
On the SM-T580 you get unusable sim-card icon in the notification bar and some other places, but that is to be expected.

Just installing on T585 now, I've flashed the rom and gapps fine.
Problem I have is first there was no keyboard, and now I can't sign in to Google account
It says checking and then screen goes black.
I've wiped cache and davlik but still won't work
Any help would be appreciated
Also, what's a full wipe in twrp?

Those problems may be related to improper wipe, no worries.
Full wipe means in TWRP you go to 'Wipe' -> 'Advanced Wipe' -> Select all partitions except 'Micro SD card' and 'USB OTG'
In my case (SM-T580) that would be;
- Dalvik / ART cache
- System
- Data
- Internal Storage (Optional, but recommended to wipe)
- Cache
Don't forget to first make a backup via TWRP of the 'EFS' partition (on sd-card or USB-stick via OTG cable), just in case the SIM-card functions stop working due to lost IMEI.
Also, some issues may be related to the device still working on stuff when it shows the welcome screen after flashing. In general you should leave the device for around 5 minutes before doing anything after flashing and first boot to let everything finish properly.

Rom is running smoothly, only problem I found so far is the camera app, it loads but the soft button only shows a half. It's like the screen is not big enough.
Is there a fix for this?

Install another good camera. For example i am using Camera FV-5.

It's honestly WORRYING the fact the tablet runs at 10FPS when scrolling through the notification bar. Can't you disable the notification bar background alpha @Valera1978?

---

Hi. Thanks a lot @Valera1978 . Good job. Even GPS work now.:good:

---

Great work. I'm new there, i've just buy a T580 and watch your thread for 1 day.
Edit : "Install custom recovery - use my twrp" Where can i find it ? Thanks.

This for T585 only. You need install TWRP for T580 official or by @followmsi better from his RR threads.

Great! I can confirm that gps gets a fix in gps test app, just as can be seen in the screenshot. Also open camera app can take photos on both cameras and video on back camera. I couldn't record video with front camera, but that doesn't bother me anyway.

OK thanks.
Is this rom still OK for T580 ? I read someone flashed it already. Can anyone confirm ? Thanks.

I can't access the SD card in this ROM, maybe there are some leftover files from the previous ROM, that prevent the tablet from accessing it? Anybody has some advice if it's possible to fix that?

Did you format it as internal storage on the last romyou had installed, if so it possibly will not work unless it's reformatted on the currently installed rom.
Does it actually show up in file manager?
