Hello! I have some poblems with my chinese tablet Lenco Cooltab 70. Three days ago the tablet discharger. When I charged it and powered it on all files were deleted! So I tried to install my old apps like Opera mobile, Youtube, etc..During the installation I got this error message " AppName could not be installed. Free up some space and try again". My tablet has got empty internal storage!!! ( storage bug?). I tried searching in Google. Every possible option failed! Next error message was during the installation new Custom ROM( Paranoid android)- acording to the instructions. I got this message:
E: signature verification failed
E: installation aborted.

Next thing I did was: update recovery mode to CWM( too TWRP). i receive the installation aborted error again. People on XDA or another forum advise to install goomanager or Lucky Patcher, but how?! I cant install anything! When I try to enter the download mode( install CWM or FLASH ROM via Odin) hold power button+ volume down it goes to Recovery mode with RED TRIANGLE!
Please help me I cant do anything...

Pics are included.

What I already tried:
- wipe data/ factory reset
- wipe cache
- install Custom ROM Paranoid
-install CWM or TWRP
-root again( SuperOneClick said: device allready rooted!)
- all options on Google
 
when did you buy it? did it work properly when you got it?

what did you think about its wifi? what method did you use to root it?
