Hi,

To install TWRP I followed the instructions there ( you have also the link to the proper odin version )
For Gapps no direct link you'll have to go to the site and choose the following options:
ARM / 7.1 / Pico
Magisk, I don't know, I don't need to root it, so I didn't search.

Thanks, I managed to install VIPER and setup successfully and sign in with my google user
I failed to root the device ( is it needed?)
One funny thing that I cant explain - I looked for Netflix in app store and couldn't find it ???

I managed to install Netflix :)
I am still puzzled what do I need the root (Magisk) for?

Amazing ROM, thanks for the contribution !

I've had the same problem with another app with the original rom (kitkat)
I've googled around and found this (sorry french version). It says that if you can't install netflix from the store, you can download an apk directly from netflix site.

However this tablet is very old. I don't think it can handle modern video definitions, playback will be choppy ...

Thanks, Netflix is sorted out from their webiste (and works fine)
My only left over dilea is now the Magisk - why do I need to Root? what's the benefits of it? My tablet works great without it

So, seems like some people have the Wifi problems while others don't.
I'm one of those who does, my Wifi disconects all the time, it says the password may be worng or authentication problems. Any clue on that?
Really love this ROM but without internet it's hard to use it right?

OTG error

Very good work in port ROM viperos.
OTG not ready.

Thanks
Hi, there is simple way to fix it if you've got rooted tablet. Does it work? I just used USB OTG as a serial terminal for my ESP32 board so I think it works fine.

1. Download Total Commander and give it root permission. (Could be any file explorer able to write files to system dir or you can manually change system directory type from read only to read/write and back again to read only).
2. You need android.hardware.usb.host.xml file, you can find it here https://github.com/newbit1/usbhostpermissons, you can download whole repository or only this file.
3. You need to use Total Commander (Or another file explorer [most of file explorers doesn't change directory type, system dir is read only by default and total commander changes it for read write to copy files]). So paste android.hardware.usb.host.xml to the /System/etc/permissions directory, after this operation Total Commander should ask you if he has to set directory type to read only, click yes (You don't want to mess with system files). If You have manually changed dir type to read write then you should also manually change it back to read only.

Tablet is OTG friendly be default but somehow it misses the driver, this simple trick unleashes OTG potential and allow you to be the host. Without that OTG works partially, I've managed to connect pendrive and even wireless mouse but somehow it could not use the usb as a serial for my board and I need to record logs on the go while driving a car, so needed to figure it out pretty quick.

I use 7.112.0 build 7 35534 from apkmirror and it works fine

You don't really need root, it helped me nothing except trick with adding USB HOST drivers to the system dir, without it it would be impossible

I added batteryfix.zip and ril_patch.zip (just after gapps).
I have no words to thank @gitanillo87 for his wonderful work.
Tested in a T561, with youtube and Vanced. Wifi and 3G ok, very fast and stable, not yet rooted.
Previously tested Lineage 14 and was very slow, crashed suddenly many times.
Next week will do the same to another tablet T560, now with Lineage12.
Thanks to all!

I'm trying to follow your steps, but I already have a problem uploading ViperOS ROM, TWRP says

E:Error executing updater binary in zip '/sideload/package.zip'

:-(

    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
