posted some screenshots. any ideas??
My fault, I've been extremely busy, with my business ventures. Let's back track. What were you doing prior to the device becoming inoperable? Are you sure the files aren't corrupt? I usually just match the downloaded file size, to the size of the original file.

I will check back in as time allows.

sorry, i been a little busy myself also lately. all i was doing was playing a game of spades and it just restarted and kept restarting. ive tried factory reset and nothing is working/ i just want to get it working again. i dont know if i can flash a custom rom on it to fix it or what?? ive tried checking the files and re downloading them in case they were bad.

When I select the link for the firmware, I get "403 Forbidden".

I thought maybe it was my VPN or a browser setting but I disabled the VPN and also tried another browser. Same result.

The only other site I found with a link to the cab file doesn't work either.
When I click on the link there it just opens a blank tab.
Anyone have a known working link for the LG870 firmware?
