[Q] LG G2 downgrade to JB with custom recovery? - G2 Q&A, Help & Troubleshooting

Hi all,
I recently bought LG G2 d802. 2nd day I installed GloudyG3 rom. Everything was fine except the VOIP applications (Skype, Viber...). Voice communication using these apps was impossible (see LG G2 KitKat VOIP/Skype bug).
I wanted to revert to stock. I saw the guide to revert to stock using LG Flash tool. I've done that step by step but program stucked, and I bricked my phone. There was no download mode, no recovery mode, no nothing. There was however qhsusb_bulk recovery option. I tried to fix the phone using this guide: http://forum.xda-developers.com/showthread.php?t=2582142, but after that I got no recovery and lost this way of recovery too.
After I replace the phone I want to revert to Jelly Bean because I really need VOIP apps (Skype, Viber, etc...).
Is there a way to flash Jelly Bean rom (stock or custom) using custom recovery? After all of this I am REALLY afraid to use LG Flash tool again.
By the way is it possible to do all rom manipulation using custom recovery and never use LG Flash tool* As the user who wants to use rooted phone I don't want to install OTA updates either.
Thank you in advance for your answer.

[Q] noob question, newly rooted G2 (D802) about custom recovery

Hello guys,, I'm a new user of G2, and have rooted it after a week when I bought it. I've searched similar following question but seems like I can't find the exactly answer I'm looking for..
So, first of all, please excuse me because I'm still new with G2..
I'm currently on Stock 4.2.2 JB v.20e rooted G2 and I'm still about to install a custom recovery into it. I decided to stay in JB since I found there are still some minor problems in KitKat firmware... My questions are:
1. If I already installed CWM or TWRP, and when I want to get back to Stock firmware, will the custom recovery disappeared or will it stay there?
2. I've read in some cases, update to KitKat from a rooted Stock JB via OTA could cause a bootloop. So if I back to purely Stock, it means the root access will be vanished right? can I update to KitKat via OTA safely after I back to Stock firmware?
thanks a lot in advance guys..
It depends on how you "restore" back to stock. If you make a backup in the recovery and restore from there, then no, the recovery will not disappear. But if you flash the stock image with adb or fastboot or whatever it's called (I think it may be called download mode) , then yes, the recovery will be gone.
It's my understanding that if you are on Jb, rooted with no mods other than root, then you can take the ota and you will have rooted kitkat. But don't quote me on that. Google some more.

[Q] Root & Roms

I'm coming from an iPhone to the D802 so I hope you can understand my unfamiliarity and obliviousness. The root equivalent (jailbreak) is child's play compared to this.
I want to install the Optimus g3 rom on my lg g2 as it seems clean and seems to rid of a lot of bloat.
My g2 is pretty new. After I have rooted it using some of the tutorials on here and install TWRP recovery (those two things seems simple enough, hard to make a mistake thereI do I just download and flash the rom through TWRP? It says something about the kit Kat baseband do I have to install that? If so, why and what is it? I am on 4.4.2 kit Kat already.
The dreaded questions:
I know all this will void warranty, if I need to take it for repair, what steps can I take?
Is there a true way of completely going back to 100% out of the box stock?
As I have mentioned I am coming from an iPhone and restoring to stock is really simple over there.

If you were on the latest ota, no need for the kk baseband... Ya just download a Rom of your choosing (you seem smart enough to choose correct device model ) then enter twrp and wipe everything except internal storage. Flash the Rom that you want and reboot. Wait 5 minutes for it to settle in. LG flash tools is the way to return to stock... Either that or sideloading the STOCK tot file...

Oh and always make a backup the one time you don't you will regret it

So AFTER I flash the G3 Rom, I wipe everything? Not BEFORE flashing?
The steps say:
* Root Your Device Here
* Flash Custom Recovery Here, A Tool To Do That
* Full Wipe (Wipe Date/Factory Rest, Wipe Cache, System, Data)
* Install The Rom
* Install KK Baseband (IF You Already Flash it Then No Need To Flash It Again)
Also, after using the LG flash tools to restore, will I be fully out of the box stock without a trace?

If you modify the ROM you won't be able to OTA. That includes custom recovery, moving, renaming, or otherwise modifying anything in /system.

Thank you for the answer! How to find a phone like the factory? Can I update with lg pc suite?
I tried updating my phone via OTA the other day, but because I had TWRP recovery, when my system installed the updated, it would boot into TWRP, and.... that was basically it, could not update, had to rollback from a backup I took moments before. Then, in a stroke of genius, I used flashify to restore the original recovery and almost bricked my device.
Big tip for anyone in this situation...
When using flashify, use recovery IMAGE not zip, if you use the zip function, it has to boot into a recovery to use it, so the image file is the preferred method, in my opinion.

Restore Recovery D801

Hello guys. I rooted my phone and i installed TWRP using the AutoRec app. Now in the past with my phone rooted only and with stock recovery if i want to get back to stock i used the LG Support Tool. But now that i installed the TWRP when i use the LG Tool and puts my phone to Download Mode i get an error. Secure Boot Error, Cause Certifications Verify and because of that i cannot enter download mode and i cant get back to stock. I have looked for ways to restore stock recovery because i believe the error is because of this but i cant find a solid tutorial. Every were i look people convince the OP to keep using custom restore or no one answer the question. So to be cleared the stock rom installed is 5.0.2 and it works i can use it and the TWRP also works i can use it the only thing broken is Download mode and i ant to restore stock recovery.

Help me get beyond Jellybean -- Weird recovery problems

Howdy folks -- I'm having issues with my G2 that I hope people here can help me with. I've already had some advice in the Noobs thread, so thanks for that.
My phone is a LG G2 D800 (AT&T) and is unlocked, being used on the Rogers network. The previous owner of the phone had installed CloudyFlex, which is what I was using until recently.
Here's the story in a nutshell:
On my first attempt to upgrade my ROM from CloudyFlex, I booted into recovery (TWRP installed by the previous owner) and then flashed the newest TWRP for my phone. I then realized I didn't have all the files needed to do the upgrade, so after the TWRP image was successfully flashed, I went to "Reboot System". Doing so gave me a non-responsive phone (LG logo then nothing but a slowly flashing LED).
I managed to get the phone into Download Mode and followed the instructions for LG Flash Tool in the first post here exactly: http://forum.xda-developers.com/showthread.php?t=2432476 which gave me a "stock" functional phone again, but one now running Jellybean (4.2.2, software version D80010o). I'd like to be on Kitkat or (preferably) Lollipop.
I am able to root the phone easily using the LG One Click Root tool. No problem there.
So that's the story. I now have a AT&T D800, unlocked and running on Rogers with Jellybean 4.2.2 (D80010o). I would like to bring my phone into 2016 by updating it to at least KitKat, preferably Lollipop (if I can). The problem is that I can't get a working recovery. Here's what I've tried:
Flashify: following its instructions exactly seems at first like it's working (I get some kind of "success" message) but when it then goes to reboot the phone, it reboots to a black screen (phone is non-responsive -- have to hold down the power button to shut it off, then turn it back on, at which point it boots normally into Android)
TWRP Manager: I've tried it as well, and get the same outcome as Flashify (apparent success followed by a black screen etc.). Once the phone is on and back into Android, TWRP Manager seems to think that TWRP is not installed.
AutoRec: I installed the version from the thread here: http://forum.xda-developers.com/showthread.php?t=2715496 ran it, and again it appeared to be successful. When it rebooted, it did go into recovery, TWRP 2.7.0.0 or something like that. Then I went to "reboot system" but got the same problem as before -- phone non-responsive, slow flashing LED, had to go back into Download Mode and flash the Jellybean TOT file, etc.
Can anyone help me figure out what is going on? I just want to get my phone to a nice stable Lollipop state with decent performance and battery life. Failing that, KitKat. Not sure what to do next.
Crisis averted: I managed to get CloudyG2 2.2 running on my phone and all seems well. Here's what I did:
I installed stock KitKat on my phone using the procedure outlined at http://forum.xda-developers.com/showthread.php?t=2663369
I then rooted the phone with ioroot (following its instructions)
I then used AutoRec to install recovery. For some reason I'm only ever able to boot to recovery directly from AutoRec -- when I try to get into recovery using the usual techniques, the phone locks up. I literally have to reinstall recovery every time and then say "yes" when AutoRec asks me if I want to reboot into recovery. Not sure why this is. The TWRP version I see is 2.7.0.0
I then flashed the KK bootloader and then CloudyG2. So far so good.
I'm a bit too shellshocked to try to install a Lollipop ROM on this phone right now. Maybe some day. In the meantime, many thanks to those who helped me out on other threads.
Why didn't you just tot to the latest rom?

Based on comments at http://forum.xda-developers.com/showthread.php?t=2432476 I was under the impression that the farthest I could get would be Jellybean. Then found the other thread with the KitKat TOT. That enabled me to use Autorec (though recovery still works wonky on my phone) so I now have CloudyG2.
