Second once I performed this step and had everything installed I realized that in order to use my wifi hotspot, I was going to need a custom rom. this was of course after trying dozens of worthless hotspot apps in the store, none of which worked. So I started trying to put a custom recovery on the phone, this was by far the hardest part, I tried and scoured the internet for 3 days, I swear to god I read every article and tried every method out there....the new ATT LG G2's however have a lock on the recovery to prevent people from doing this, I found it strange that none of these articles written based on 4.4.2 thought to mention that an exploit has not yet been found. Finally I ran across an article where I learned of this and was told to downgrade, so I downloaded SuperSport & big fau LG G2 D800 Flash stock. Thinking that this rom was going to unlock the recovery because it said it would, I ran through the process.
This however, was not the case and it didn't help, the whole time I was convinced that this had unlocked my recovery, I continued to try every tutorial on installing a recovery onto this device, the AT&T LG G2 kitkat 4.4.2 (D80020c), which btw is a week old from the date of this post. I like a lot of other people, will have this phone and be looking to unlock, root, install custom recovery, and install custom rom. For this I would like to figure out a few things and hopefully if y'all help me figure this out, I can include fixes for it in the next article that I write, which will explain how I successfully put a custom rom on my AT&T from start to finish. I will also include in this article what could go wrong and how to fix it, too many articles are written without taking into consideration the possibilities of what could go wrong.
It took me three solid days of scouring the internet to get a custom Rom on my phone, running through problems at every step I still have a few questions. After downgrading from 4.4.2 to 4.2.2 my recovery was broke, thankfully I was able to fix this using flashify in the app store. I then installed Cyanogen Mod 10 (cm-10.2.0-d802.zip). and installed it through recovery, when I rebooted I was presented with a fastboot which would do crap when I would plug the usb into my computer...I never figured out what the problem was for this, but I ended up trying a version of CM 10 which was released for the LG G2 D80010d that I downgraded too, the tethering doesn't work...no big deal, but the problem is when I set WiFi hotspot up and connect, on my computer I get SSL error's, my computer completely refuses to let my connect to facebook or google, saying that the connection is insecure, it won't let me grab any kind of certificate and I can't find a solution online. I have tried rebooting both the computer and phone, I don't get these errors on the WiFi at the gas station.
In the above paragraph, I stated the two problems I couldn't really figure out, I haven't tried to install any other custom roms, but I will try that today, I have to save my bandwidth on my phone so I will walk down to the truck stop and download one, ps I had to flash my phone back to stock about 5 times before I finally figured out I needed to downgrade it, then I had to do it 2 more times.
If y'all take the time to read this and help me, then I will take the time to write a new and working article describing how to do it from start to finish and it will be written with explicit detail on every problem I came across and how I fixed it.
