I rooted my lg optimus g (e970) and removed a bunch of the preinstalled apps that are supposed to be unremovable such as youtube and the at&t navigator, etc. I then set the cpu to be about 900 (no idea what that means but I think it was ghz). I restated my phone to see if the boot up would increase but it says "security error" under the LG logo and won't turn on. I don't care if I have to reset everything I just don't want to have to take it to an at&t place or get it replaced! I backed all of the stuff I cared about up.
Flash KDZ Stock ROM

I'll give you all the info I can as this has all happened since last night.
Yesterday I was bored, and decided to Root my SGH-I747M [Virgin Mobile, runs off Bell I believe] I used to jailbreak my apple products all this time, my S3 is getting old so I figured heck why not. I was curious about all the Kit Kat hubbub lol.
I Rooted it successfully, then installed the CyanogenMod 4.4 Nightly Custom Rom onto my phone.
That was also successful minus two things that happened, I don't like some of the features & I lost cell service [NOT due to and EFS/IMEI issues]
Decided to downgrade and unroot as the only reason for rooting was to install Kit Kat.
Unfortunately trying to Unroot something went wrong, after pushing start in Odin and my phone froze in Download Mode and Odin failed.
After rebooting my phone I got the typical "Firmware upgrade encountered a problem" so I hooked up to Kies, entered my phone model and s/n and did a full Firmware recovery.
Still had no cell service, could make calls but no SMS.
Found a post that said to take out battery, take out SIM card, boot, then take battery out, replace SIM and reboot.
I believe I have full service back with no issues.
But after the Kies recovery, I have this constant screen on my phone as picutred in the attachment!
I can use my phone, I can touch anything/everything it doesn't block anything thats behind it, but that screen stays. It goes away if I need to go into settings but it comes back shortly. My phone is also still set as "custom" in the info so I'm assuming it's still Rooted???
Update: A friend of mine suggest doing another Kies recovery. So I'm waiting for that now.
And I'm not sure if it's still rooted, Went to settings>More>About Device>Status> And Device Status reads Official.
Alrighty another update incase anyone reads this and can either help or point me to help lol, I am searching forums/google like crazy trying everything.... I figured out that the screenshot is showing me factory mode is on.
Turned it off, after re-rooting and installing SU/Root Explorer.
So factory mode is off, now my only problem is Mobile Network: Disconnected despite Service State: In Service and all the other stats seemingly normal?
It seems I can make calls, but I can not use data or send sms/mms.
So in a moment of stupidity I somehow was able to install a D855 rom on my AT&T D850 phone. Turns out these roms wont let me hear my phone calls and continually drop my data connection and cell service. Turns out I made another stupid mistake and forgot to make a backup of my phone . So I tried to do a factory restore back to D850 using the LGflasher method and I can't because I now have the D855 software on it and so I'm now stuck without the ability to make phone calls or have a reliable data.

What exactly have you flashed on your phone? Bump, root, KDZ/TOT file?
If you want to go back to stock you could either follow the guides on the forums or flash a .tot/.dll on your device, that way you get stock recovery, boot and rom etc..
I could link you the guides, but they are all in general forum or on Google
Good luck
So I used iOroot to root and then bump to put twrp on my phone. Then I decided it would be smart to flash the AndriodNow rom and then later the SphinX rom. I have tried to go back to stock but the lgflasher thinks my phone is a d855 because of the roms I flashed on it.
Hey everyone,
I am needing assistance on what ROM is good to run for my T-Mobile LG G3, unlocked device, on AT&T? Just to get it going, I wiped everything, including external SD, and had to run the flash tool and go with the C (stock) rom, then rooted with Stump root. I installed Dirty Unicorns, to get it going, but quickly ran into trouble.
Battery doesn't display correctly (100% all the time) and, I know its a feature thing, but when I Google search for numbers to call and click on numbers, it doesn't auto place them in the call screen. Also, my phone will randomly lose all cell signal (maybe its a modem issue??). When it loses signal it shows, to me, every possible APN in the world. When it is working, it only shows AT&T APNs.
Again, just looking for some guidance with anyone with knowledge of going to AT&T. Even pointing me in the right direction would awesome. Thanks in advance guys.

i use the stock rom from tmobile on my lg g3 but i use att service.
i found that the stock software works best for me, all i did was root and twrp, after that i used titanium backup to remove all apps and items related to tmobile then installed the stock lg g3 boot and shutdown animations so my phone is pretty much vanilla no branding except for the tmobile logo on the back cover which im ordering one that just says lg g3.
Hello! So I am in need of some help. So my problem is that I cant get my pc to recognize my g3, adb won't see it, I can't find it in my device manager either. Here's why I feel like I'm doing something wrong, I successfully rooted it and everything was gravy. Then I had a noob moment and accidentally deleted the settings (when I tried to access settings, it would force close) so I ended up having to use the lg flash to to get it back working. Now I try to use the exact same process to root and no matter what lg mobile driver I use I can't get my computer or adb to see my phone. I'm running Windows 7 64-bit and Att lg g3 850 5.0.1
i was wondering if any one has a easy way to root the G3 MM 6.0 stock..im looking for a One-Click roots
i want to delete all the bloat apps and unlock the phone settings to i can pick what cell band i want and enable wifi calling etc...i just need it rooted and i can do the rest, just not to good on the rooting part its been a while
FYI this is for the D850 AT&T
AT&T D850 MM has wifi calling build in, but I definitely concur with the need of a full root method for it. Perhaps it would improve the battery consumption issue. Android 5 I could leave the phone in standby mode over night and still have 100% battery the next day. MM uses 14-16% battery in standby mode
Been here all day looking for a method to Root this D85030K build.. Tried a couple, the purple drake, it pops up 2 cmd prmt windows that just hang there, no command to reboot device or request for me to enter DL mode, unless just take it on my own to do so and see..
The Oneclick brings me to some screen on phone claiming a firmware upgrade in progress 0% do not unplug, but the app states FAILED, so I've had no luck, unsure if anyone else has, someone said to use Stump, haven't done that yet...
