Help Upgrade Epad Android 2.1 to 2.2?

i know this has been asked before but i am a real newbee and cant follow how to do it. so my apologies . also apologies for posting here but i wanted it to be where zt108 owners were.

i have the above. its ok for what it does but the battery is making in a totally non portable epad. i do not use it as a phone. but i am only getting between 27 and 54 minutes from a fully charged battery. when i check where it went to it says 87% went on cell standby.i have turned off all the connections related to cell phones eg, 2g & 3g. i have downloaded a startup manager, turned off everything running and tried to stop the dailer from turning on, to no avail. i have tried turning dailer off via running processes, wont turn off. cant find anything else related to a phone anywhere.other forums have said to rename the phone file but i cant even find the phone file. some people on forums have reflashed and sorted it but i am to scared to do that without very clear plain english instructions.

where does this cell standby originate. and how can i turn it off or uninstall it. it will never be used as a phone.
 
I cant open root explorer... it says : root explorer has not yet managed to obtain root access. Because of issues with superuser ..... restart the app.." i restarted, but there is no use.
 
In order to use rootexplorer you need to root using UniversalAndroot and select the "do not install super user" option.

I renamed telephony.apk and Phone.apk which got rid of the cell stand by in battery usage. I had to reload Utube with the latest version after doing this but had no other issues. I am using a V2 (512mb 4GB) zt-180 10" tablet.

Two reasons for short battery life are defective batteries and having the screen brightness set way too high. I set mine to about 25% and it is fine. I get about 3 hours on a full charge with wifi enabled, a bit longer if I turn that off.
 
Is there any other way to change the mount r/w to mount r/o . The button does nothing when pressed. So I can't. Edit the file?
 
get the newest versions of both .apk.

it will work then.

also droidtweaker seems to have a make rw option for file system, you could try that as well
 
If u use the androot.apk change the option to install superuser to do not install after root is obtained. You apparently don't need the superuser app on the tablet. Mine has not had any issues with apps needing permission since I removed the superuser.apk.
