clarification
this is a port rom, so it is likely that when you connect the device to the PC or via bluetooth it shows a different model, it is normal since it is a hybrid between the original rom and the port
the rom it on beta state so please report any problem

I'm not a developer, I only have some general knowledge, and experience porting rom, but I don't even have Linux installed

I leave the link of the original rom of the g360h that has almost the same hardware as the tab e, all the recognition for the creators of it

FAQ

Be sure you are using T560 or T561 device,other tabs are not compatible

Go to quick setting and in the screen of the edit toggles, add brightness toggle, and switch brightness from automatic to manual... Then can control manually the brightness And we need to remember to do not touch the icon "A" at the brightness toggle

you need root,use magisk or supersu,later, download smartPack from play store grant permisions, go to Wake Gestures tap on disable and check apply on boot,and reboot

its a knowed bug,try to solve changing the wifi 2.4 channel,and conect fist the bluetooth device and after,turn on the wifi

Thanks for the port, can you give a brief description of the tweaks & customisations made in v2. I have flashed both v1/v2 & don't notice much difference between them, both filesizes are exactly the same. Both have been most stable and I've noticed no issues.

Hi there are not many differences between v1 an v2 only some tweaks on build.prop file, and some apks recompiled for a full deodex system

Battery: Devcheck: 2000 mAh before. Now, after fix it shows 5000 mAh.

There is something wrong with brightness controll, it stucks when I press "auto brightness", restart helps.
Is it possible to remove caller and sms app ...from 3G? And first of all - is it possible to update security?

Brightness control fix

Go to quick setting and in the screen of the edit toggles, add brightness toggle, and switch brightness from automatic to manual... Then can control manually the brightness

Does anyone else experience a crash when tapping ' security' from the settings menu on v2 ?

(edit) Seems I had an app/service frozen in SD Maid which was causing this, unfreezing rectified matters.

Hi guys, just went to grab a SM-T560.

God it's tedious, so here is what i did :
1) flashing TWRP 3 with Odin: done
2) flashing from twrp:
* venomfullv2.zip
* fixbattery.zip
* opengapps7.1.2arm.zip (nano for me)
* lastest supersu.zip
3) reboot (TWRP reported i have no OS installed hu ?)
4) waiting 5 to 10 mns

Everything is ok, except i can't change brightness. Do you have a fix / tip for this issue ?

I saw sometimes advices to flash boot.img, but not sure why (my tablet booted fine even if twrp reported no system installed).
My goal is to have a reactive tablet. I heard Samsung 4.4 is bloated and that Venom is the best (and furthermore 7.1.2), i hope i choose the best horse :D

Also, what is samsung know (i guess a Secure Linux like module ), and is it active on Venom ?

Thank you !

Hi everyone, just installed and everything looks ok. Unfortunately, you do not see the percentage of battery when the tablet is charging when turned off (by pressing the home button). Any solution?

    I have recently installed this rom on my old Samsung Tab E (SM-T561) as stock firmware (android v4.4.4) does not support MS Teams or Zoom. After installing this rom, now I can use both MS Teams and Zoom without any issue.
    Already mentioned bugs are noted (offline charging indicator problem and display brightness problem).
    Otherwise, the ROM works really well and very useful on my old Tab E.
    Thanks a lot developer...
