[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]Rooted Bin kitkat files?

hello, just got this phone yesterday. are there rooted bin files/kdz files for kitkat for this phone? care to link me to one if there is? firmware doesnt matter thanks!

more questions: can i flash international kdz files onto my lg g2 (at&t)
i came from lg p925, and i'm just wondering if most things will be similar, like same lg flashtool application and r&d flasher stuff. thanks again haha

Don't every cross flash kdzs please I don't think you can anyway haha
Sent from my LG-D802 using XDA Free mobile app

any other comments? i dislike "think" xD

No cross flashing is a no for the device, some people do it at their own risk but with d800 a tot cross flash wouldn't work with the dll and tot file not matching the bin/model check just stick to the roms for your d800, as for flashing you can check out the back to stock thread on the general section and the method you would use is the flash tool with tot files

so after i root my phone, i can just use rom manager and flash cwm recovery, right? how do i enter recovery? i'm not familiar with lg g2 at all yet haha. and can i flash roms right afterwards? or do i need to install wkparks (or was that only for my previous phone)/uboot files?

Well to install recovery it depends if on 4.2 jb then which of all the versions are you on d80010d/o/q or are you in kk 4.4 d80020c/k
If on d80010q/o then downgrade to 10d then root and install custom recovery with freegee from play store, if on d80020c/k the you can install recovery via auto rec
If on 4.2 then after flashing recovery you can flash any aosp/jb Rom without worrying, but if you want a 4.4 stock/flex/pro 2 Rom then you will also need to flash a kk baseband, if on 4.4 then you can flash any 4.4 stock/flex/pro 2 Rom without issues but if you want aosp then you will need the kk baseband that's been ported to aosp or the jb baseband/If flashing 4.2 stock/flex based roms you will need the jb baseband, hopefully I am not forgetting anything

Well I am not sure what you mean, for d800 you can only use flash tool with tot files, if you are asking if there are pre rooted flashable tot files via flash tool then as far as I know their aren't any

Any kit Kat Rom that's either 4.4 flex/g pro 2 ported, 4.4 stock based as long as it supports your d800, any aosp Rom with the correct baseband as long as it supports your d800

[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 does work with 20u the only thing is it breaks knock on/knock code because lg don't release the source already

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.

Yes there is a way, theres an app you can install called Autorec, this application will automatically set up a Custom Recovery for you to backup your files, here's a Link to get started.

Thanks for the fast reply, well i read this comment on the link you game me, im just curious and also worried that i might brick my phone, cause im a total noob when it comes to these things,
Here's some of the comments i read about D802T
"Please note you cannot install custom recovery in stock KK via any method for the D802T Australian variant and get it to boot. LG has not released kernel source code for Aussie variant, for KK, so Loki exploit does not work. If you want a custom recovery under KK you will have to install a custom ROM with already patched kernel. If you plan to stay on JB 4.2.2, however, you can indeed root and/or install TWRP without hassle on stock."
"u cant use this on the Australian version D802T.
It will soft brick your phone."
Now what should i do? im just very confused.

there is a way to do it. Follow the guide and root kk but before you install autorec, make sure you have a custom rom zip ready to go on your phone sdcard and whilst still in TWRP (dont try to boot into kk yet), simply flash your custom rom, and then the phone will boot normally.

[Q] D802T with a different KDZ??

As we know D802T does not support TWRP it goes into bootloop. Any one here from Australia with model D802T tried flashing with any other KDZ? if yes can u tell me which one and if there were any issues with it like baseband etc??
I want to install roms and not able to since i cant install recoveries on it..also is there a chance to sideload rom from adb?
Any suggestions are appreciated.
Thanks

The kdz flash will just fail. A lot of people have tried doing that, it just doesn't work. Also, the problem with autorec is that it flashes a patched kernel that doesn't work with your d802t firmware and will end up bricking it. The recovery does work though. So theoretically, if you flashed a custom rom right after flashing the recovery it should work. I don't have a d802t though so I can't test it.

That requires a custom recovery and flashing twrp through adb would require Loki which doesn't work on kit kat. It's disappointing that you couldn't flash a rom directly. Maybe you should try flashing an aosp rom like cm after autorec and then go from there. Otherwise, downgrading to jelly bean through a kdz flash is your only option. You just need to find some jb firmware first.

LG D-802T firmware issue
Tried flashing custom rom (CM13) after flashing recovery (TWRP) on my LG D-802T (Australian); it started off fine but then ended up bricking the phone: "Continuous LG logo"
Tried flashing it with UK open ROM, failed again.
Did The Australian D-802T stock ROM, worked...
So concluded that it doesn't support others.
