I have this tab long time, and I never update anything there. Because of very slow browser I decide to update my system. But there was a problem, Acer community shut down that option and I can update my system only manually. Ok, I debug USB in settings and using SD card tried to update new system. I found isystem on Acer web page. But instalation aborted and I can't use my tab anymore, there was no any system because new instalation delited old system. I tried many time to update new system but no results, with every instalation packagr I have same result:
-- Install /sdcard ...
Can anyone help me with some advice or link. I'm not profesional with computers and programs but I can lean a lot.
I lost three days on this but no result, I can't do it alone.
Thanks a lot
