Root URGENT! LG L86c Optimus Showtime "Secure Booting Unsuccessful"

[TheShadowhand]

I rooted my LG L86c Optimus Showtime. I uninstalled some random app that came with it and I could uninstall with a special app like Twitter and Google Play Movies. Now I get "Secure Booting Unsuccessful Cause: errorlogo" I found that Google Play Movies has some DRM stuff in it that the phone checks for when it boots, and if it is not there, it fails the security test, and does not boot. I need help trying to get my phone in working order. Please ANYONE help me through this step by step. Just bought this phone and now it's a brick. I was able to get it to the "Download is in progress. Do not disconnect cable." screen if that helps. I also downloaded the original .cab file for my phone I just don't know what to do with it all.

Plug your phone into your PC. Look how to get it into download mode. From there you can restore your software.

It doesn't stay on long enough to do this. After the error message it shuts off.

press and hold the volume down and the home button at the same time, and press and hold the power key until it starts recovery. see if you can restore it to stock by doing this. after it comes up asking about pressing power or other buttons release all the buttons.

when it comes up asking you to press the power button twice doing so will lose all the data on your phone but it should get it up and running again.

The app he removed was a system app, so going through recovery process won't fix the problem. The only fix is to re-flash the factory firmware cab file he downloaded.

I have the same phone and just rooted it myself. Now I am afraid to remove any of the crap that they installed that I don't want.

I wish they would come up with a working custom rom for jelly bean for this phone.

Yeah I've been trying to figure out a way we can get custom roms but so far I've had no luck. LG has really made this phone a pain in the neck lol

where did you find the .cab file?

 

[peteyallison]

I too have the exact same thing happening to me.

I have tried everything. In fact, I am willing to ship this phone to anyone out there to see if they can fix it.

Has anyone had any luck finding a fix to this yet?
