How to install lineage os and twrp on a stock 4.2.2 LG G2 ? - G2 Q&A, Help & Troubleshooting

I reverted to stock using KDZ flashing and then I rooted the phone using IOroot. There are many methods to install twrp and I'm kinda lost. I don't want to brick my phone again. I know a guide that tell you to kdz flash stock KitKat and use autorec but I don't know which kitkat .kdz to download from here: http://storagecow.eu/index.php?dir=Xda/LG+G2/Stock/KitKat/ Previously I used this Poland OPEN D80210E_00.kdz to revert to stock. Which one should I download? Unless there is an easy way to install twrp on Jelly Bean of course. I would appreciate if someone could provide me the needed files to install LineageOS correcly (bootloader/bootstack or something, I don't really know much about flashing android roms)

There are a lot of guides... You just have to read. Example:

[Q] CM11 Problem.. Help Needed

Hi all,
I am interested in the CM11 ROM. Last night I spent 6hrs trying and failed, epically.
Here is what I did already:
1. Downgraded from 4.4.2 back to factory
2. Successfully rooted
3. Installed ROM Manager
4. Successfully downloaded CM11 and latest GApps
Then when I tried to boot into recovery it kept going to a screen with a little android guy lying on his back with a red triangle!!! I tried six times.
I got frustrated and just updated back to 4.4.2 and have been dealing with it. I am still rooted and have been able to remove my bloatware and other things you need root access for.
Any thoughts or help as to how I can install the CM11 rom?? I am happy running NovaLauncher and using DynamicNotifications to approximate it but really want to try out CM11.
Cheers and thanks!
Lucky there is no way to root on 4.4.2 yet or atleast no Recovery's yet it could be worse you're atleast rooted and it didn't brick your phone

Did you actually try flashing a recovery first? Just installing ROM manager won't install the custom recovery needed to flash ROMs. You have to do that step as well.

No, I didn't. I am super new with android. Had an iphone for a long time. How do I flash a recover? Can I still do it now on 4.4.2 b/c its rooted?
Sorry about the noob questions, everyone is being very helpful!

LG blocked the Loki exploit with 4.4.2 so you can't flash recoveries currently. You'd have to flash back to 4.2.2 to do that. Which if you want custom ROMs now its going to have to be done sooner or later. Which carrier and model number do you have? If you have an international D802 the above post by @zekurosu will work for you, otherwise don't use that one. You're gonna have to find the method for your model number.
My first guess was that you missed the flashing the custom recovery step, which people above me have already helped ya out on. For being new to Android you did fairly well, you just missed that one step.
Good luck!

I have an ATT D800 running 4.4.2. I can't decide whether its worth it to flash back to 4.2.2 to try again. Pretty happy with NovaLauncher + widgetlocke and fairly closely approximates what I am looking for.
For what its worth, I was in 4.2.2 when I tried the first time and failed. I think mackster is right, I didn't flash the custom recovery. I basically flashed back to 4.2.2->rooted->tried to boot into recovery (OVER and OVER) then gave up and upgraded back to 4.4.2.
Thanks for all the help. At least I now have a rooted phone and have been able to do some cool stuff with that. My goal is to get nexus 5 software in an LG G2 body (battery, camera, etc)
@android_nashville There's a way to have the best of both worlds. You can flash back to 4.2.2 (10d preferably) root, flash a custom recovery with Flashify or FreeGee. Both available on the play store. Then actually update to 4.4.2 following this thread http://forum.xda-developers.com/showthread.php?t=2483043. Eventually, if you want to flash custom ROMs you're going to have flash back to 4.2.2 and do this process regardless. The 4.4 aboot image (bootloader) can't be bypassed with Loki. Its been blocked. But some brilliant devs basically found out they can make a hybrid setup, with the 4.2.2 aboot, and everything else 4.4.2. This way you can have the ability to flash custom recovery, kernels and ROMs.

Bro,
Had some doubts before i flash:
1) You mentioned do clean wipe and flash that ROM. Do i need to install stock recovery and stock kernel before that? I have custom recovery (CWM) installed right now.
2) After installing your this ROM will my phone be official, unrooted? Will i be able to get the official OTA updates in the future?
Please let me know.

Done and running official 5.0.2 now. Hope will be getting future official updates from now on. Thanks a ton bro. :good::good::good:
I flashed the the 122 mb update and got the error, but it was fine when I flashed the OTA LP again and flashed the incremental right after it.
But unfortunately (or fortunately ) my Mac address was lost had to flash a custom kernel to make it work. Was it the same for you?
And I don't see much difference with the phone, the battery lasts around 8-9 hours on games (heating is still on).
I do like to know if there's any difference for you guys

Please correct me if i am wrong

Hello guys,
Please excuse my noobish question, but i need to find some good answer.
I have a Samsung Galaxy Note 3, model number SM-N9005 with Android version 4.4.2.
The phablet is rooted thanks to Towelroot. And from there i install Titanium Backup and many others intersting stuff that need/or not root.
I enjoyed Xposed and i'm thinking i want to enjoy CyanogenMod also.
Now ... my problems is that i am very confused about what i have to do next.
And after i spent some time to research this, i've come here for some guidance because i fell that i'm running in circle.
My questions are :
Do i have to upgrade to Lollipop first ?
Do i have to unroot from Towelroot and root again with Odin ?
As i saw that steps are as follow:
1. Need root
2. Install TWRP
3. CyanogenMod (as i saw 12 is the last and it's good for my device)
Many thanks !

1. Unique way to update to Lollipop (if you are rooted) is via ODIN. I don't recommend you update anyway. I still with android 4.4.2.
2. No. Only flash the new firmware via ODIN and root it then with ODIN too.
3. I don't recommend you install CyanogenMod if you are noob.
If you do want CyanogenMod, you only need to install TWRP, and then flash latest CM-12.1 nightly build in recovery. You do need to wipe /data first, though which means you will lose your apps and settings.
Always make backups!

So why do you dont recommend to me to upgrade to Lollipop ?
Is Kit Kat better at this time than Lollipop ?
If i will update via ODIN, is there a better way to do that ?
And ... Still have my question about what if i'll unroot (and how can i do that safe) and root it by examples via ODIN and then follow others tutorials with TWRP and CyanogenMod. I'm not confortable via ODIN (but if i find some good, trusted tutorials, i want to try it) because as i told you before i rooted my phablet, the easy way via Towelroot.
2. No. Only flash the new firmware via ODIN and root it then with ODIN too.

If you want a CM rom just flash recovery with odin. No need to root. Then backup your phone and flash the CM rom. No need to upgrade to lollipop either.
However if you want a lollipop TW based rom it's better to upgrade to lollipop first. Nevertheless you can still try lollipop TW custom rom without upgrading to lollipop first but some functions may not work well.
If you can root your phone with Towelroot and you don't want to use odin to flash the recovery, you may do so by dd with terminal emulator.

What ROM to install for replacing an old ROM?

I am currently running OptimusG3 V1.4.1 rooted, used TWRP, for over a year, and it's time to change. I have d802.
I need a new ROM that will be fast and clean. My main uses are surfing the net, whatsapp, music etc... nothing too demanding.
What ROM do you recommend?
Also I need a guide that tell me exactly what to do because I don't want a brick. I don't want to mess something because the modem version is not okay or something like that.
I want to make a clean install and remove all the things that are currently on the device. I want everything new and fresh on it.
If you need more details, please ask.
Thanks

if you have KK d802. this is how i do it .
you already have root and twrp right? i asumed as you have that rom on phone.
if not just search for root method for your variant/ and search for KK autorec for your variant.
then i would recommend updating your twrp, with blastagator thermal control twrp from here.
choose your variant. just flash thermal twrp to installe it.
http://forum.xda-developers.com/lg-g2/development/twrp-twrp-2-8-0-0-kernel-f2fs-tools-t2898705
this is to take you to lollipop. am not sure if you want to stay in KK. if you do all you got to do is follow the roms installation instructions.. in rom thread. ... if you want to go lollipop then follow procedure.
back up al your data to pc.
go into thermal twrp. wipe all partitions including sd card. this will be a clean installation.
you can transfer files while you are in twrp too..
install this bootstacks for your variant. when install, reboot into recovery NOT TO SYSTEM. to take effect.

back to stock like from factory ithink you need to use TOT or KDZ method using flashtools.
follow the guide here . no when you do KDZ or TOT id deletes everything puts phone to zero state resets everything. no need to worry about baseband..
