Good evening,

I have a tablet 70 oxygen and I need the root for the GPS: I use the tablet for my drone only and to optimize the GPS it must root.
The firmware currently installed is: [email protected]
I get a firmware (70 Oxygen \ V04_20161220_fp20160620_3b517cf_8dbc211_Calliandra )

Thank you for seeing if an issue is possible,

cordially

Hi i dont own that tablet any longer but i seem to remeber a root solution called vroot . I think i had the archos 70 cobalt not sure if that is even the same model or not . If it is or is compatible your in luck it was one click root method the only way it could be easier is if it didnt require pc . Additionally tgere was a cwm recovery built for the device good chance it might if the device uses rockchip board and processor set. The root solution was for a number of arccheros devices that utilized these board

I was able to unlock the bootloader, but was not able to create a TWRP to root the device.

The problem was, that I was not able to download the current ROM. Where did you get the ROM?

Here is a post how to create the TWRP:

Hello,
This is a very good job you did, bravo !!! Unfortunately I do not have a link for the rom, I have already searched on the website of the manufacturer but they did not put it online, I was also on the forum "archoslounge" without result.
I do not know how to extract the rom I have to send it, sorry. In any case you have made a very good advance!

I have been able to boot a twrp-image on my archos 70 oxygen.

Unfortunately something I did has bricked it (twice). At least I know how to rewrite the partitions now, when it is bricked and getting it to life again. But every try needs at least an hour ...

TWRP for ac70ox
I attached the TWRP I created and I used to root my device with Magisk.

Attention: I have not tried other functions and the possibility you will brick you device is very high. It can even brick it just by starting the TWRP and then rebooting to system. It happend to me many times and it was necessary to restore the device with SP Flash Tool.

I will not help you - you are on your own.
