LG G2 w/ no ROM installed. Got TWRP and Download Mode working - G2 Q&A, Help & Troubleshooting

Hey.
So, I got Windows 10 and tried the *.KDZ method but it gives me the connection error and I couldn't find anything as to how to fix it, so I tried adb sideloader, it only allows me to install custom ROMs I guess? It doesn't work with .kdz files or something I guess.
So, I have TWRP installed, my download mode is working but someone tried to do a "hard reset" and wiped out the SO on TWRP, can anyone tell me what to do now please?
Thanks!
PS: I already got my stock .kdz downloaded from LGs official website.

Which model G2 do you have? Which version of android are you coming from and which did you try to flash? Which version of TWRP do you have and is it bumpted?

Hello, it's my sisters phone and it's a D805 from Brazil
She had a OPTIMUS G3 installed and I tried flashing with the D80530A .kdz that the LG website gave me. She's got the 2.8.3 release and I don't know whats bumpted but it's rooted and I got it to reinstall the OPTIMUS G3 (latest version) to it, but I still can't get it back to stock.
Thanks for the help.

Since you have TWRP you can try the method discussed in the link below ..... I recommend you upgrade your TWRP to 2.8.7.3 first though.

LG L7 - How to revert to stock?

Hello guys,
I'm going to sell my L7, it's too slow, and I'm a bit tired of installing things to make it a bit faster.
So, my question is... How to revert to stock firmware? Currently, I've installed V20A (beta, I think), rooted, and CWM. I want to install V10K.
Can you guys help me? Thank you.

Links don't work.
But I want to delete everything, including CWM. I want to put the L7 100% stock (firmware and recovery).
Up.
I'm going to sell it tonight, so I really need to solve this.
I want to install V10i from Vodafone Portugal and then I'm going to update the phone to latest firmware, via LG PC Suite. Is this possible?

[Q] Development for the LG G2 from videoton/WIND D801V11B

Hi all, I have a LG G2 from Videotron model LG-D801, variant D801V11B. I pretty sure it is the same model for WIND user. I got it rooted with the chinese method. I did not find any TWRP image for this device so I tried some and finally got it working with the openrecovery-twrp-2.6.3.2-g2rog.img, every other image/version i tried put me in a black screen with white character saying something like: [760] Fastboot mode started \n[800] udc_start(). I think I tried every version i could find up to 2.6.3.7.
Now each time I try to install a custom rom on my device i get this error: error executing updater binary... And it seems that I am unable to find any custom roms that was developed for my phone. I was wondering if a section could be made for the canadian version of this phone and if someone could help me put a custom roms on it. Ho i wish I could put paranoid android or hellfire kitkat on it tired of the stock rom
Thanks in advance
Same here... I'm stuck in fasboot mode with access to CWRM from D803. I can install a modified version of CM11, but after boot it goes back to fastboot. All other ROMs I tried so far fail.
Anybody successfully flashed a 4.4.X rom on this variant ?

Got here late but better late than never. In theory D801 is a D803, and every d803 rom should work on it. Paranoid has a version for d803 that has worked pretty well on my phone but I wouldnt recommend it. There is a workaround for installing d802 roms on this phone by changing the updater script and afterwards flashing a d803 kernel.
I could make you a zip with any d802 rom (cm11, aokp, probam, etc) that could work on your phone without flashing any additional files. Just tell me what rom you prefer and what kernel and done

If I am correct currently you are running 2.6.3.2 and are trying to flash a kk based aosp Rom well the problem is the recovery it won't flash it because it's before the kk binary, the only way to be able to flash the Rom is to find twrp 2.6.3.3 or higher
Sent from my LG-D800 running stock kk, rooted with philz using XDA app

Your "D801" is really a D803. Use the tools in this thread.

[Q/help] blisspop 3.5 from stock lollipop d802t

Hi all
Didn't want to post in the official devs thread so I thought here would be most appropriate
I fresh installed kdz for 5.02 on my Australian lg g2 d802T with root and twrp. All good.
I tried to install blisspop 3.5 using the instructions
Boot into twrp,
Install bootstack 802 from lg devs
Install ROM
Install gapps
However after all this I have endless boot logo for blisspop.
Anyone have any ideas?

Hmmm you flashed a d802 bootstack correct? Don't you need a special d802T modem? I get a bootloop when I use a d802 modem on my d806 (same device, similar but not identical modem).
I realised had to wipe system and data first. Whoops.

Problem installing TWRP on my G2 D802

Hello there!
So i just got an used G2 and i've been trying to install TWRP but i can't get it done.
I tried so many methods including AutoRec and all i get is an error when booting in recovery.
I've seen alot of topics about this but its all old from android 4.4 and i'm running stock 5.0.2.
Even on TWRP website there isn't an option for the D802 model.
Is there any way i can install a custom ROM on the phone? Any fix for that?
use blastagator's twrp... not the official one
search for "blastagator twrp bumped" on lg g2 forums...
although i saw that his download site is down atm... but there is a mirror on dorimanx server too
Thank you for your answer but i just manage to make it work.
Flashed stock KitKat 4.4.2 then followed the steps with the old guides.

Lineage OS 16 on LG G2 (d802t) installation problem

I have an old LG G2 device (LG D802T) LTE variant I tested to install Lineage OS 16 on it knowing, it supports only the LG D802 but I still try it and unfortunately it didn't work (good thing I made a backup) do you have any suggestion for me to install any custom rom for my device that could work?
Thanks

Problem solved!
Updated my TWRP by flashing the TWRP provided in blastgator
I can now flash the latest Lineage OS just fine.
Any chance you can explain this in more detail? I have the D802T (Australian variant) and haven’t had any success with getting LineageOS installed. Currently running the stock Lollipop build.
I can root the phone via the LG One Click Root tool. But after installing AutoRec for the D802, I can’t get into the OS anymore - it just cycles between the LG logo and “Security Error”.
I’m able to update the TWRP via the Blastigstor zip’s...but once I download the LineageOS nightly zips and try to flash them, they fail at the first step with an ERROR 7 message - unsure if this is because its looking for a D802 and my phone is a D802T.
Any suggestions?
