[Q] Unable to boot Stock based ROMS [D800]

Hey everyone, sorry if this question has been answered already. I have sifted through pages and pages in this forum and haven't found a solution for my D800.
My G2 is rooted, with TWRP installed. I was successful in flashing Paranoid Android v4 beta 4, and 5. The problem arises when I try to flash LG Stock based ROMS. After TWRP says flashing was successful and I try to reboot, the screen shows LG logo for a second and turns blank!! That's it just a clear black screen, and the ROM doesn't boot at all.
The ROMs I tried and failed to boot:
1. Aeon
2. Korean stock based rom
3. Scott's CleanROM
4. Rayglobe 3.2
5. Rayglobe Flex ROM v4
Now, I know that sometime ROMs take time to boot on the first run, so I even tried leaving it at the blank screen for 15-20 mins with no result. Since it has been the same result for multiple ROMs, it definitely isn't a bad install or a bad ROM download either. I hope not
Is there anything I am missing in the steps? All ROMs were installed after factory resetting through TWRP (no dirty flash). I am baffled with this, please let me know if I need to revert to software version "d" for these ROMs to work?
TIA

Did you factory reset after as well? If I recall correctly Paranoid Android is AOSP. What kernel are you running?

sounds like you are onn the 10o update. You will need to flash back to stock 10d with lg flash tool and then root and install recovery again. Then you should be good to go on flashing roms. I know that some of the newest versions of TWRP and Philz have issues flashing some roms too so that may also be the cause. If you downgrade the recovery you have to the version right before it may fix your issue also

Exactly, AOSP ROMs are booting up fine but not the Stock based ones.. I am not flashing any kernels, just the ROM, so I'm assuming it will run on either the stock kernel or the kernel included in the ROM zip?
Have you been successful in installing such ROMs? Am I missing something in the wiping part? Only been doing the factory reset in TWRP before installing any ROM.

Check m
And make sure that you are running the stock kernel. Are you on the 10o update?

Oh, I hadn't thought about anything being wrong with the recovery.. Always assumed it gets the work done
How do I find previous versions of TWRP compatible with D800?

Yes I am on 10o.. Does it have issues with installing other Stock ROMs? If yes, I'll try to follow the thread on using LGFlash tools, I've never done that before. Hopefully its not much difficult to follow the instructions.

That is one of the easiest guides to follow. Be sure to follow the correct set of instructions(depends on carrier) and download the the 10d version.

I'm stuck in the process! Can't change the com port number to 41. The guide is pretty easy to understand. But when I put my phone is download mode and try to change the com port number, it says I don't have the write privileges for this device's setting. I've tried it on both Win 7 and Win 8 laptops, with LG mobility drivers installed.
Is there something in the phone settings I need to enable so that I get the write privileges to change com port number?

Do you have administrator privileges?

Yay!!! Finally did it!
Issue 1: If faced with write privileges for com port (tried successfully in Win 8)
Solution: After going in to com port properties, click "change settings" and there is the option to change com port number.
Issue 2: Once the port number was changed to 41, rest of the instructions are easy to follow on this thread http://forum.xda-developers.com/showthread.php?t=2633150
Once on D80010d, I rooted with ioroot22, and installed recovery using FreeGee. Just installed Rayglobe 3.2 minutes ago, and it finally booted up!!!
So, the bottomline is that go back to D80010d if you wanna play with Stock based ROMs! I flashed with TWRP 2.6.3.3, so the fault is not with the recovery. That much I can confirm
Thanks for the suggestions guys. Thread solved I guess.

Great. Glad to hear it.

Thanks for the input. Before I flashed back to D80010d today, I installed older versions of Philz and TWRP but neither helped. So downgrading was sort of a compulsion, in my case at least.

and the moral of the story is, unless you are getting an android version upgrade in the update, do not take the update.

[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.

Any Rom ZVC Compatible Yet?

I have been on Stock ZVC Rooted for the past few months and there are some things driving me nuts about it. For one the navigation bar at the bottom is too sensitive and I accidentally hit the home button when I am doing things and 2, the portrait to landscape mode is too sensitive. The 2 questions I have as of right now is there any ROM updated for ZVC yet and if not, is there a way to install the Xposed Framework Module on Stock ZVC being rooted?

Not sure what you mean about if there's a "ROM updated for ZVC yet"
Are you asking if there's a ROM based on the stock ls980 ROM?
And as far as I know regarding xposed... Go right ahead and install the apk as long as your running on dalvik and not on ART. But i might be wrong about xposed since I haven't been running on a stock for a while

Wasn't sure if the Cyanogenmod team, or any others had updated their roms to work based on the latest version on the LS980 aka ZVC aka stock kitkat but before the release I know some people said they had issues due to kernel differences/bootloader issues/etc, I don't have a custom recovery running stock zvc at the moment, just rooted.

Early on there were some problems getting custom recovery, however Cloudyfa developed AutoRec which is a app that installs a custom recovery (TWRP) without any hassle whatsoever.. All you gotta do is install the apk for the ls980 which can be downloaded from here http://www.androidfilehost.com/?w=files&flid=13763 M
Make sure to read the full OP for AutoRec: http://forum.xda-developers.com/showthread.php?t=2715496
Now this is my preferred method to install cm
1) make a nandroid backup, wipe everything besides internal storage
2) downgrade your modem to ZV8 from ZVC (the reason for this is that the cm kernel is not compatible with the ZVC modem)
3) flash the latest nightly
4) flash pa gapps
5) reboot system to enjoy a crisp and clean cm rom
Link to all the G2 modems: http://forum.xda-developers.com/showthread.php?t=2451426
Also please note that this method takes away the ability to have sprint spark.
Another thing... if you ever want to restore your nandroid backup make sure to flash the ZVC modem first

If I flash the Furnace AOSP kernel and the ZVA modem instead I'll get spark, right?

[Q] I have the AT&T model D800. I'm having trouble reverting back to D80010d. Help?
I tried following this method in this thread: http://forum.xda-developers.com/showthread.php?t=2432476
I started with D80010o and ended up on the same firmware.
However, I noticed that the TOT file says V10o. I searched back on old threads and saw that this is the file that I probably need: LGD800AT-01-V10d-310-410-AUG-14-2013.zip
I can't seem to find that file anywhere though. Can someone point me in the right direction? Thanks!

Why do you want to revert to 10d? The only reason to do so before was we needed the old bootloader to be able to flash custom recovery. You can achieve the same result now by using AutoRec by @Cloudyfa. It does everything for you easy peasy (need root to use it) .

This is true but, AutoRec won't work with the newest update for the d800 (v20u for knock code). I'm in this boat right now. V10o was also giving issues back in the day as well.

AutoRec worked just fine for me on 20u. I always like have a rooted nandroid of the latest release so I restored to factory via lg flash tools, updated to 20u, rooted via ioroot25 and immediately flashed twrp 2.7.0.0. No issues whatsoever.

So, it breaks knock on/code only on stock? I'm going to AOSP anyhow. Or would I be better off just going back to 20c KK? I was going to go back to JB and go from there.. but it just seems like it's a bit unnecessary.

Theres no reason to revert all the way back to JB. Its a waste of time. It breaks knock code for 20u. As far as other roms idk. I know mahdi had it working last time i used it but ever since cloudy released his flex and G3 roms ive stayed with those.

D800 won't take any AOSP ROMs

Hey guys and gals. I have my old g2 that I rarely use anymore, but want to tinker with. My problem is that any LP or MM aosp ROMs won't fully boot. They all just bootloop forever. I've tried different versions of twrp. I've tried just about every bootstack. I've followed flashing instructions to the letter. It's currently running serenity 5.0.2 because stock based seems to take fine, and serenity is relatively debloated. I should add, the laptop fried a few weeks ago, so I'm trying to figure this out via mobile only. Any insight would be greatly appreciated. I'm at a loss here.
