Root old tablet files missing

[pomkon]

this galaxy tab p7510 is android 4. many apps cant be used.

thought im not sure it is fast enough for android 6/7. it may not be laggy after flashing, but android 4 sucks.

 

But I need to root 1st :

 

I found this guide to root but the update.zip is missing

also is this site safe?

Is that a big dif between android 6 & 7 ? should i just go for 7? is the 

Dual-core 1.0 GHz Cortex-A9

 fast enough?

Android 7 is for the most part identical to Android 6, the main features are that you can have native multiwindow support and some miscellaneous optimizations. If you have a choice I'd say get Android 7.

 

Also I'm not sure the tablet has any official or unofficial release of Android 6 or 7, so that might be another issue entirely.

 

If anything, you should look for another rooting tutorial on the XDA forums, they would have more reliable info and resources for your device.
