Need Help With my D800 Please

I do not normally post on here, just read and learn =) However, I'm having an issue with my G2 for AT&T. I have a Nexus 6 and cracked the screen, I was trying to get my G2 up and running until my replacement gets in. I had CyanogenMod on it but did not turn on the phone in quite a while. Got an update, did that and nothing was working. Could not even get Google Play services working at all. Flashed a random ROM to see if it would help and now I cannot even get into recovery. The phone operates fine, however if I try to do the power button + volume down button to reset the phone, I get to the point where I hit the power button twice and the phone resets. I've selected rebooting into recover a hundred times with no luck, it will get to recovery and before I can hit anything....reboot. Last night I tried to go back to stock with LG Flash Tool (after downloading everything I need to download) but keep getting Fail after unplugging my phone and plugging it back in download mode. I know long paragraphs are not well liked here but i feel i'm sort of o ut of options other than reaching out to you awesome people! Just wanna go back to stock at this point. I've never had this issue where I cannot even get into recovery but the phone work perfectly fine! grrrrrr

Unbrick LG G 2 D800

I own an LG G2 D800 AT&T Version. I was running Stock Android KitKat 4.4.2 in Unrooted and Boot loader Locked condition. I had an idea to shift to some Custom ROM for G2. I selected and downloaded CloudyG3 3.3 for that. Now my phone is bricked and in NO RECOVERY, NO DOWNLOAD, NO FAST BOOT MODE. What I only get is Secure Boot Certificate Error and Demi God Crash Handler with Critical Error . Which says Press Up Volume for Download and Down for Reboot. I tried doing Factory Reset but it results in the same and same goes for Download Mode.

These are the steps I followed:
1. I Rooted my phone based on Stump Root and following these instructions and was successful.

2. I then Installed TWRP recovery using Auto Rec APK according to following procedure.

3. I then copied the downloaded CloudyG3 3.3

4. I booted into TWRP and installed CloudyG3

5. Before that I backed up my phone EFS and System only

6. After installation I performed Factory Wipe to Reset

7. My phone went into QUSB mode I think only LG logo and Black Screen

8. I followed the procedure after downloading IMG files of 30f ROM for D800 as mentioned in the link below

9. I DIDNOT although Flash Recovery of TWRP in the end.


The result is I am stuck in DEMI GOD Crash Handler and Critical Error Mode kindly help! Cannot do anything

Disable LTE on D800?

Hi guys. LTE is terrible at my house, but HSPA+ is fine and LTE kills my battery. Is it possible to disable LTE on a D800? Either stock or on a flashed ROM? If not I'll have to try another phone that allows it. I have an old MetroPCS F6 I've been using and have LTE disabled, but I wanted something faster and more up to date so I gave the G2 a shot.
