Hello, I got a samsung galaxy tab 2. I am very new to rotting and all that, i rooted the tablet using this guide and it has worked
droidviews.com/root-samsung-galaxy-tab-2-10-1-wifi-gt-p5110-on-android-4-1-1-jelly-bean-firmware/
I am trying to accomplish two things with it:
One- Getting the OTG to work with it. It didnt work straight away with the adapter and I have had little luck finding a soloution. THe app USB OTG checker says I have the usb otg api, but when i plug in a usb drive it dosent recognise it. I think i may have to install a "Kernal" to fix this but i don'y know how to find one that is compatible and will work. (I am doing this for my mum so she can use a usb drive and i dont want to brick it)
Two- this is the main goal, to get ethernet connectivity on the tablet, i think the otg will have to be fixed first but i am not sure. I cant get it to work and apps that enable the ethernet connectivity like:
google.com/store/apps/details?id=xda.usbhost.test&hl=en
Require some kernal. I have su and busybox installed already.
I have a samsung galaxy tab 2 10.1 GT-P5110 with android version 4.1.1 and kernal version 3.0.31 - 523998
Thank you very much if you can help me
