Unfortunately, LGATCMD Service has Stopped

[VirgilX00]

This is a technical question I have with my LG Optimus F3.

I have an unusual problem with my phone. A couple of days ago, an error message took over the screen reading, "Unfortunately, LGATCMD Service has stopped," and no matter how many times I press "OK," it will continue to reappear. I have tried to Force Stop, Clear Cache, Clear Data of several of the programs in my Application Manager, but nothing.

Following, I have done a Restart, Soft Reset, Hard Reset, Factory Reset, wiping the S5 System Cache, changing batteries, removing SD card, and switching SIM cards. I tried to get the phone to connect to the internet so I can try installing an update, but it continually runs into an authentication error. To add, there is no service for the phone.

In order to do anything on the phone, I have to press "OK" on the error popping up and I have 0.3 seconds to press or swipe on the phone before the error pops up again. It gets frustrating when I'm trying to find a solution. Unfortunately, I have run into a dead end and cannot find a solution anywhere.

If you can help me in any way possible., I would greatly appreciate it.
Thank you

To add, I'm sorry if this is a double post. I created my other thread as a guest, on the Android Questions forum, so I'm not quite sure how to delete it.

Old post, I know, but I had this exact problem on my LG D390n and managed to resolve it on my own. Since I couldn't find any solution on the web, and your post was one of the first Google hits, I thought I'd share what I learned in case it helps someone else.

Like you, I had already tried a factory reset, only to see the same error dialog appear afterwards. However, recalling that the last firmware update I did was via the "LGMobile Support Tool" on PC/Windows, I started this tool to see if I could maybe coax it into reflashing the same image over USB.

The tool managed to contact the phone over USB, but only once I got past a few of the first steps in the "first time installation" that follows a factory reset (I think it connected at the step where you can transfer data from another phone). It was a bit of a pain, of course, since the "LGATCMD" error dialog appeared all the time making it difficult to click the appropariate buttons. Once connected, the tool determined that I already had the last version. However, there was a menu at the top where you choose "options / upgrade error recovery" (translated from Swedish, so the quote may not be exact). Choosing this, the tool started to download, decompress, and reflash the latest version, which took a few minutes. But once it was completed, everything worked OK again! No more "LGATCMD" error! So it was probably a part of the system software or configuration data that was corrupted in flash, and repaired by the recovery procedure.
