Why is there like no activity in the d802 subforums?
[G2 Q&A, Help & Troubleshooting] Sunandroid:
It's best if you perform a "normal flash" with the lg tool. You will lose no data at all. For a link have a look at the second post of this thread.
[G2 Q&A, Help & Troubleshooting] d00lz:
Yes, Return to Stock firmware and read carefully next time. Use an application like StumpRoot to Root your device, and then use AutoRec to install TWRP for you.

Follow the Return to Stock thread and it will put you back on Stock firmware, with Stock recovery. You can then take the OTA update. Note: Like [MENTION=5744495]Sunandroid[/MENTION] said, make sure you choose correctly between CSE and Normal Flash depending on your situation.

There a few ways to check,

Method 1. Power off your phone.

- Jellybean Bootloader: Hold PWR + VOL DWN, when LG Logo appears let go and hold PWR + VOL DWN again.

- Kitkat Bootloader: Hold PWR + VOL DWN, when LG Logo appears let go and hold VOL UP + VOL DWN.

Method 2. Open Terminal and type the following,

su
reboot recovery

If you have TWRP recovery it will boot you straight into it for you.

Method 3. Like [MENTION=3279781]bender_007[/MENTION] said, open a file manager and navigate to /sdcard and look for a folder labelled TWRP.

/sdcard can also be found at /storage/emulated/0 and /storage/sdcard0 as it has some symbolic links attached.

What are you talking about. There is a lot of activity in the D802 subforum, I'm in it regularly. You just need to observe it over a period of time, not from one initial glance or even 1 week.
[G2 Q&A, Help & Troubleshooting] AntiCommon:
Hi everyone, I've been banging my head against a wall for the last 5 hours trying to figure out what's wrong with my D800. I would appreciate any and all help, and I'll explain what I've done so far and whatnot.

So for starters, this is a phone my brother has been using. It was running a version of CM or PA (not sure which) and he complained this weekend of random reboots. I was going to go ahead and just load CloudyG2 on it this evening but then he said it stopped booting altogether.

So now it's in a state of constant black screen (screen is on, just black). I can hard boot it to show the LG splashscreen sometimes but it never loads past that. I can also get it to show 'download mode' when I press up and plug in a usb from PC.

When the device is connected to the PC usually does one of a few different things:

my PC simply doesn't recognize it (windows tells me so)

it is recognized and shows about 20 different partitions (qhusb_bulk in device manager)

goes into recovery but I'm still not sure if the PC actually realizes that its doing anything

I've tried doing the LG flash tool and have used it before on this and other devices, but since I can't get the drivers to work properly (or maybe the drivers are working properly and the device is the issue) I can't get it to send a new image to the device which would be super easy otherwise. I've tried following the steps for the unbrick method below but since I can't get the partitions to reliably show I'm kind of SOL.

https://www.youtube.com/watch?v=_d5b_osUTug

There was another thread about this which mentioned using ubuntu but I don't really have access to that ability nor do I have any knowledge about using ubuntu to begin with, I've mostly only messed around with android stuff and this is one of the hardest bricks I've come across since my last 6-7 devices. Hopefully you guys can help steer me in the right direction because I've just about had enough. :silly:

Edit: I've got the screen to show up where it asks for factory reset but nothing happens afterwords. I can't remember if there was TWRP or CWM installed beforehand, but in either case it's not loading it.
[G2 Q&A, Help & Troubleshooting] kliurkius:
Okay, thank you. I did that and i see that i got twrp recovery. What would you suggest me to do, to go back to original recovery and install official lollipop via OTA, or just download and flash it myself. Not sure what method is better
[G2 Q&A, Help & Troubleshooting] d00lz:
Just because you have no knowledge when it comes to Ubuntu doesn't mean you should ignore it as a solution which could possibly fix your device. I recommend you download Ubuntu 14.04.2 LTS. use Rufus to copy it onto a USB stick and then boot from your USB. Select "Try Ubuntu" on the splash screen instead of "Install Ubuntu" and follow this tutorial. All the knowledge you need is in that thread, it's very straight forward. If you have any problems, post in that thread. I or someone else will be happy to help you if you get stuck.

Just to clarify, can you or can't you access Custom Recovery?

If you have a custom recovery like TWRP you don't want to install any update, trust me. You will bootloop.

Follow the Return to Stock tutorial which will return your recovery back to normal. You will lose root but will be able to take the LP update.

Just to reiterate, if you have a Custom Recovery - do not take the OTA update. if you only have Root with no Custom Recovery - you can take the OTA update.

[G2 Q&A, Help & Troubleshooting] omfal:
Thank you.

I read that thread but it wasn't clear to me whether I would have gotten at the same time also the original recovery, instead of only firmware.

If you say I will get them both, I will proceed.

Thanks to [MENTION=5744495]Sunandroid[/MENTION] too.
[G2 Q&A, Help & Troubleshooting] d00lz:
The .KDZ you download from the tutorial will reset your phone 100% back to stock.

You will lose everything you ever put on your device and all partitions will be wiped and replaced with the original partitions you had when you very first bought your device. These partitions are unmodified and come from LG themselves.

Back up your data, Return to Stock by flashing your KDZ, and then take the OTA update.

Phone not going into Recovery or Download mode

Fellas,

I recently changed my build.prop defaults to some random value for testing.

After restarting my phone was stuck on boot loop.

Upon checking, I found that my recovery was broken and I was unable to go into download mode either.

The phone was rooted and was running on stock kernel with Android 4.4.2

I saw various flashing tutorials but couldn't find one that doesn't require booting into download mode.

Is there anyway to recover the phone?

I saw somewhere that the phone is unbrickable.

Any help would be really appreciated.
[G2 Q&A, Help & Troubleshooting] d00lz:
Why did you do that? Never change settings to random values for testing unless you can afford to lose the phone, in other words.. be a developer of some sorts.

What value name did you change in your build.prop, and what value did you change it too?

Can you access any form of Recovery?

Is your phone detected by Windows or Linux when plugged in via USB?

There are 2 methods to access Recovery depending on your bootloader:

1. PWR + VOL DWN, when LG logo appears, let go and again hold PWR + VOL DWN.

2. PWR + VOL DWN, when LG logo appears, let go and hold VOL UP + VOL DWN.

Read this thread.

Also read this thread.
[G2 Q&A, Help & Troubleshooting] Sunandroid:
Just a short explanation again: You can use kdz and then take the OTA and use the oneclick root & recovery tool for getting a recovery again or you can just flash one of the zips available here on xda in your recovery. That won't erase your recovery or something like that. So it's basically the same thing like when you just use the oneclick tool. So it's your choice.

But in your case I'd definitely choose the second one since it takes not half of the time of the first one. lol.

Glad to hear that and well done!!! :good: :good: :good: :good: :good:

I cannot access the custom recovery, just the screen that appears before it. The recovery itself may be corrupted.

Also since I was running a version of AOSP beforehand will the method you linked to be safe for me to use? It makes mention that I must use a version which matches the firmware on my phone but currently there is none since they are all from LG.

currently running 4.4.2 stock kitkat, but twrp recovery

I would really appreciate it if you can tell me what lollipop kdz file i should download to flash it myself. thanks

EDIT : nevermind, i think i found it myself over my imei number
[G2 Q&A, Help & Troubleshooting] ~SUDHIR~:
Thank you for your reply.

I changed my phone name and model number to Samsung and SM-E700H respectively, just to claim an offer. However, things turned out really bad.

My phone shows up in device manager when connected in switched on stage ( While the LG is constant).

Yes I can access recovery by PWR + VL DWN and then VOL UP + VOL DOWN but I guess there is no recovery installed. Only the phone was rooted. Hence, it just asks me " FOrmat User Data and Settings?" and when I select yes, the phone simply restarts after a while.
[G2 Q&A, Help & Troubleshooting] kliurkius:

One love to you mate, was checking what you said above but decided just to flash stock rom via LG flash tool to go to lollipop stock and just root my phone and get twrp again. that was kinda easy. and as always i cant wait more than 2 months before flashing anything to my new device :D
[G2 Q&A, Help & Troubleshooting] Sunandroid:
Bootloader. Baseband shouldn't matter. You have to be on JB Bootloader for blisspop. So either flash 4.2.2. kdz, reroot and reflash recovery or use autorec to downgrade bootloader and then upgrade recovery again or just flash the flashable JB bootloader by [MENTION=5236920]zg85[/MENTION] (at least for the d802).

From a little stalking of your profile I see you have a D801 (T-Mobile) variant.

bender_007 has released AutoRec for the D802 and D801 which will Downgrade your Bootloader and flash the TWRP Recovery image for you. It can be found on the PlayStore.

PlayStore - (D801) LG G2 AutoRec-Lollipop

Using this app requires you to:

1. be on stock 30a / 30d lollipop

2. have a rooted device

I just bought a D801 on eBay, it conveniently came with 4.2.2 D80110g installed, so I rooted successfully with Towelroot. After that, I disabled OTA's from the LG test menu.

My question is, since 4.2.2 is so outdated, it's very hard to find instructions on how to install TWRP since almost everything is written for KK. How do I flash TWRP on this software version?

Update: Nevermind, I used the Loki .img method but through Terminal on my phone instead of ADB.

VS980, Validus 4/1 nightly

I am having problems with my speaker. I can not get music to play, alarm to sound, phone to ring or the speaker phone to work. Sound works with headphones and over bluetooth. I had the same problem on Liquid Smooth 3/9 nightly. Both were clean flashed. When I first flashed Validus I had the speaker work briefly (phone rang). I have checked and sound level is on and there is a sound selected for phone ring and alarm. I do not have google now installed.

A few days ago, I was using CM12 with TWRP 2.6.x.x (I can't remember specifically). I went into flashify to update my recovery to the newest TWRP and now when I boot into recovery, it gives me a secure booting error. I am using the D800 variant and I am rooted with towelroot. I'm a bit unsure about other things, but I will try my best to find any other info needed. Do I need to downgrade to KitKat and then update TWRP and then install CM12 or do I just download AutoRec and go on from there? If so, how would I go back to CM11 from CM12 without a custom recovery?
[G2 Q&A, Help & Troubleshooting] Sunandroid:
You get this error because your recovery is not bumped. Means the KK (and higher) bootloader recognizes your recovery is not prooved by LG and doesn't boot it. So autorec, and then upgrading to this one is the way to go. It works with the KK bootloader too. Maybe you should have a look at the second link in my signature. ;)

[G2 Q&A, Help & Troubleshooting] swetz:
Don't you just love a noob questions? I know I do!

So I'm new to the Android ROMing game and have some questions with my new LG G2.

I've been looking at tall the custom ROMS and notice they all come with some of their own quirks. I was looking into the Resurrection Remix ROM because I wanted to get into the Lollipop game right from the get go. I was looking through all the different versions of that particular ROM and saw people having problems with the latest version and reccomending an earlier version. Is there an easy way to see known bugs per version? or basically, how do I know which version will be the least problematic for me? Basically which one should I pick lol. But I don't just want a reccomendation, I want to know if there's a standard on where to find that info.

As far as the CM builds, is it correct to assume that the M build's will be the most stable? So a CM11 build will probably be pretty stable as they have M builds, but the CM12 builds which are still in the nightly development stage will probably run into bugs/aren't as stable as the M ones?

Another thing I've been looking around for are ways to use the quickwindow in custom roms. Is it only the Cloudy G2 rom that will support that? Is there no app that will provide that functionality on different custom roms?

One other noob question since I have you all here, as far as the recovery software, let's say TWRP will it always be best to use the latest version, so like from the TWRP website I see it's 2.8.6.0, is that the best practice there?

Thanks for all of time people spend answering these questions in advance. I'm sure some of it can be found in the vastness of xdadev. I truly appreciate your time and patience!
[G2 Q&A, Help & Troubleshooting] Art Vanderlay:
You'll find that every ROM thread is like. But most of these 'bugs' are the result of user error or caused by other factors based on their usage. That's why there is no list, we all have to try them and go through the testing stage ourselves for these roms.

Yes M builds are the most stable. Nightlies are the latest and greatest but might have bugs.

I don't know about this. There used to be app but I'm not sure if it works on lollipop.

When Im doing a fresh install of twrp I pick the latest one every time. I rarely update it though. If it works fine I'll stick with it.

Thank you so much for all your time! Those are the basics of my questions, I think I've got a good starting point for getting in to the ROMing game. Any good starting points for getting into android development? I've looked into code academy as an intro into android app development, but it'd be interesting to see what goes into building the ROM's as well!

It sounds like alot of the custom ROMs involve trial and error when it comes to trying them out. Is there a way to just install the rom without having to install all my standard apps every time? Like say I like a game and don't want to lose my progress, or if I don't want to have to put netflix on the phone with every ROM I try... is there a way to do that?
[G2 Q&A, Help & Troubleshooting] Sunandroid:
Well if you don't have any experiences in development, It most probably will be hard for you to create your own ROM. Building isn't that hard. A few commands in the terminal are usually it. But most developers here on xda also work as developers in their daily life and have got some skills in development over the years.

And ROM development isn't the same as App development of course.

Either use Titanium backup or just dirty flash (-> google) ;) . If you want a better understanding about android, read, and get some basic knowledge. You might start with reading the second link in my signature. ;)

1) You probably mean lollipop. No, I don't know about one. But you might try cloudy G3 (renamed to cloudy G2). It's G3-Based, but the LP update is pretty similar to this one. There is no such ROM because the source-code for the D802 has not been published yet AFAIK.
