I am facing an issue with the display of my LG Gpad 8.3, running latest Android available for that model: 4.2.2.
My issue appeared after installing an app which was not from the PlayStore. The app has no icon and can not be removed, that's why I am inclined to believe that in my case it is not an hardware issue (but I am not ruling it out completely).
Besides that the unresponsive strip occurs exactly on the area where the confirmation dialog boxes for this OS appear.
What I have done so far
Luckily my tablet is not something I use daily. Most of the time it stays in the drawer and turned off. So I have no fear of losing any data in case of hard-reset, although I feel the malware might access my google account data.
Anyways, I tried to hard reset the tablet using the standard LG tools & key combinations, as explained here: http://www.lg-phones.org/how-to-flash-unbrick-lg-g-pad-8-3-back-to-stock.html
The installation completes, but the "malware" remains in the system.
On top of that the
About Phone -->
Hardware Information is broken. It shows all
I think the only option I have is to use a "dirty way" of wiping the phone and reinstalling the OS.
What should I use in that case?
Or, do you have a solution for this exact problem?
Edit: Some additional information:
- I think my phone is not rooted because I reverted it back to stock couple of months ago, due to camera issues. I tried the bootloader combinations, none worked.
After all, I think the problem might not be related to the malware :/. It might well be a hardware issue.
- I formatted the device and reverted back to an older version of the stock rom. The unresponsive strip is still there.
- I rooted the device and installed TWRP, just to see whether the unresponsiveness will remain in the TWRP menu. Unfortunately it did.
- Wiping everything in the phone using TWRP, but I don't know how to do this.
- Installing a new OS; one that is modified.
Important: The CSN is still all 0s, as shown in the picture.
