Hey :)

I need to know which variant of G2 you have.

I think there went something wrong with AutoRec and you need to flash back the partitions files or/and the kernel.

Just tell me which variant of G2 you have and I'll try to help you.

I tried many Android L ROMs but official CyanogenMod is what I like the most. You could try more of them and see which one suits better for you needs. Many 5.0 ROMs are based on CM so they are very similar.

Need a little help. This is the third thread I'm posting this'd on because i have not gotten any help as of yet and need a working phone. This is for vs980.

I was on aosp 5.0.2 from nobe1974, downloaded the 27a bootstack, 27a debloated ROM and 27a radio. Went to recovery twrp wiped, flashed 27a bootstack then when I tried to flash the ROM I got and error and now I am unable to flash anything. Tried to restore 26a stock rooted and it goes through the whole sequence but when the lg logo comes on I get a message on left top corner "boot verification error" then a black screen comes on and stays there. I can still get to recovery and tried to flash aosp rom back but gives me an error, I don't know what to do next. Can anyone help? Thank you.

Does anybody know if Viper4Droid works on CM12 ? I never used Viper4Droid and I was curious to see how good it is, so I downloaded the latest app for (4.4) from xda, installed the driver, reboot and I opened the Poweramp music player and turned on Viper4Droid for headset and I didn't noticed any change :/..I tried too for speakers but no difference.

EDIT: Flash CloudyG2 and Dorimanx kernel. Then you should be able to boot and install Autorec to switch back to JB bootloader.
[G2 Q&A, Help & Troubleshooting] luvtorev:
How do I flash the jb boot loader now that I can't boot the phone? Thank you for the quick reply by the way.

I really just want to get back to stock and now sure how to do it when the phone doesn't boot up
[G2 Q&A, Help & Troubleshooting] raulx222:
You could go to stock too, power off device press volume up and plug your usb cable. Once you are in download mode use LG Flash Tool.

But I think it's easier to install CloudyG2 + Dorimanx kernel and use Autorec. You could install them via adb sideload from TWRP or if you have the latest TWRP you can use MTP to transfer the ROM and kernel to your device to can flash them.
[G2 Q&A, Help & Troubleshooting] Sunandroid:
Have a look at the second post of this thread. There is a link to a guide, called something like "how to back to stock". Follow this guide and you are completely on stock. All your data will be gone afterwards. :-/

If the App is made for 4.4, the drivers are most probably for 4.4 too. Since many things (including sound stuff) have changed with Lollipop, I'm pretty sure it won't work, until the dev brings up a variant for 5.0 ROMs...

Is there a way to boot into downloader mode on D801 on 20g currently?
[G2 Q&A, Help & Troubleshooting] raulx222:
Download mode can always be accessed from any bootloader.

On KK bootloader like I said: power off, hold volume down + power, when lg logo appears release buttons and press and hold volume up + volume down

On JB bootloader: power off, hold volume down + power, when lg logo appears release buttons and press and hold volume down and power button.

EDIT: Sorry, that was how you boot in recovery. [MENTION=5744495]Sunandroid[/MENTION] gave the right answer.
[G2 Q&A, Help & Troubleshooting] severectify:
When I try to do this, my phone boots into safe mode, not download mode. Do I need to plug in the USB cable at any point?
[G2 Q&A, Help & Troubleshooting] Sunandroid:
Turn your phone off, press the vol+ button and plug-in the usb cable. That's the way I do it and it works for the D802. And should for other variants too.
[G2 Q&A, Help & Troubleshooting] severectify:
This doesn't work on the 20g update for the D801 - LG borked the standard download mode trigger, whether it was on purpose or on accident. I was wondering if there's some other way to do it because right now I'm stuck with a dummy root script in system files, which prevents me from using stump root. I can't downgrade without download mode and I didn't flash a custom recovery before updating and breaking root from towelroot, which doesn't support this update. I've been trying to figure out how to update recovery from LG Mobile Support Tool, but I keep getting a "No upgrade items to fix" notice despite most other users being able to redo the firmware update and break the dummy root script that's still inside system and allowing them to stump root and subsequently AutoRec.

At this point I'm convinced that I'm stuck without root until Lollipop; please tell me if there's some alternative method I can use other than tearing my phone apart with the hardbrick fix or replacing the phone.

I'm not sure if it helps, but you tried to do a factory reset and use again LG Mobile Support Tool?
[G2 Q&A, Help & Troubleshooting] severectify:
I've already done a factory reset in hopes of it somehow letting me stump root, but it didn't work. I did try LG Mobile Support Tool after I did that, and didn't try it beforehand.

Thanks and a question or two...

I'm pretty sure I have a bunch of people to thank on XDA, but I didn't thank them on the way, some things worked and others didn't, and I don't know who's who, so thanks everyone. I rooted my lg with stump root, installed the TWRP system recovery, created a back up, tried to upgrade to lollipop and accidentally wiped the backup while soft bricking my phone. Got out of that, bricked it again trying something else, but the backup was intact this time. I then tried downgrading from VS980 27a down to VS980 11a. Stump root doesn't work on 11a, so I rooted with ioroot. I tried crdroid to upgrade to lollipop and voila! Only took two and half days! I'm at 5.0.1, it's a great update and all is well. Question #1: am I rooted anymore? When I try rootchecker, it says no. I can still reboot to recovery, and that says I'm rooted. Question #2: Is there anywhere to go from here other than 5.0.2 or future updates? On Christiano's crdroid site, I saw no mention of lg g2. Is crdroid something that gets updated like CWM does (nightlies, etc)?
[G2 Q&A, Help & Troubleshooting] Sunandroid:
A recovery (with root rights) is not the same thing as root rights on your android. So you are probably not. Is there already an official update for the VS980 to Lollipop or did you take CM12 or another custom ROM? If it's the second, you usually can go to developer settings (by tapping 7 times on the bulid nuber in system settings you make the dev-settings visible) and activate. If you can't, download the SuperSU zip and flash this in recovery. That's it. You are rooted again. ;)
[G2 Q&A, Help & Troubleshooting] mrodela:
Thanks, Sunandroid. I flashed three things when I upgraded to lollipop (because I read you're supposed to, not cause I know what I'm doing :p ) : The crdroid Rom, gapps, and the SuperSU zip. I just flashed it again just in case. That being said, I just opened SuperSU (the app) and it says "There is no SU binary installed, and SuperSU cannot install it. This is a problem! If you just upgraded to Android 5.0, you need to manually re-root-consult the relevant forums for your device."

Is the first part of that essentially saying it wants to ask for root access, but there's nothing to ask for root access since it's probably not rooted and there is nothing SuperSU can do about it?
[G2 Q&A, Help & Troubleshooting] Sunandroid:
That's what i thought. Unlock the developer settings and do the steps i told you. Then open the SU app and then you should be able to grant root rights to the superSU app. install the binaries and follow the other steps. ;)

btw. Hitting the thanks-button is much appreciated ;)
[G2 Q&A, Help & Troubleshooting] mrodela:
If by "activate" you mean turning "Root Access" on for Apps and ADB, that was on by default. Another root checker says I have root as does Busybox, but once I'm in Busybox it won't let me install anything. Something's messed up me thinks.

Where's the Thanks button?
[G2 Q&A, Help & Troubleshooting] severectify:
I've just tried another computer and it still doesn't work; it still gives me the "No upgrade items to fix" notice.
[G2 Q&A, Help & Troubleshooting] Sunandroid:
Well.... Are you sure you have flashed the right version of SuperSU from here?

This was the way it worked on CM. And because your ROM is based on CM, it theoretically should work the same way. But Apps & ADB is the right setting... Anyways, in worst case I recommend you to flash another LP ROM or wait for an update (which fixes the issue; was like this in the first few nighlies of CM too) of your ROM. ;)

SIM Card w/custom ROM

I currently have my VS980 on the wireless provider Page Plus. It's not flashed in any way as Page Plus now supports 4G LTE sim cards. I am not really a flashing noob as I have been flashing ROMs and otherwise for a few years. But I am new to how SIM cards affect a phone on a custom ROM.

My question(s) is this:

Will running a custom ROM change anything about how the sim card takes it programming etc?

Part of the reason I ask this is because of most of the roms I am seeing (at least Lollipop ones) are telling me to flash modem files if you use their roms.

It is also worth mentioning that Page Plus I believe uses the same frequencies and all as Verizon.

I hope I am not repeating a question that has been asked before. But I did search etc and couldn't find an answer.

And thanks a ton in advance,
[G2 Q&A, Help & Troubleshooting] Sunandroid:
I think you have to wait until the more popular variants get the LP update and the devs make a root method for them. I don't know a root method that's working with official LP...

Lost TWRP recovery and no OS

Running VS980. Attempted to flash Paranoid and got stuck at LG Logo with error message Secure Booting Error. Cause: boot certification verify! Not typically a problem, except when i try to boot back into TWRP, it is gone. I am presented with stock recovery only providing the option to do a factory reset. Next problem, i dont' have a functional OS to reset and boot into. What do i do?
[G2 Q&A, Help & Troubleshooting] mrodela:
I'm running VS980 myself, so allow me to ask what may be a dumb question, since it seems you would already know this since you already tried to flash something but...... when I boot into TWRP, mine always says that if you push the power button, you will do a factory reset, and then it asks again to make sure. Once I do, however, it boots into TWRP (teamwin). Are you saying you get past that screen asking about a factory reset and there's nothing there?

Also, I had the most recent over the air update on my VS980. I downgraded from 27a and then flashed crdroid to get lollipop and as far as I can tell, it is working nearly flawlessly. That may be another option once you get it squared away.
[G2 Q&A, Help & Troubleshooting] Sunandroid:
press that power button twice in the factory-reset-screen and you are back in TWRP. That's normal if you boot into TWRP with the button-combo.

Recovery, knock on

I tried rooting and installing Cyanogen on my LG G2, but that ended up not working so well (white line problem, bootloop). Luckily I was able to go back to stock, with the LG Mobile Support tool, but a few things don't work anymore:

- Accessing recovery with the physical buttons on startup (I tried the vol down + power combination as well as the vol down + power -> vol up + vol down).

- Knock on.

These two things worked perfectly before I flashed a stock rom. I tried using the LG Flash Tool 2014 with the correct image for my IMEI and then using the Mobile Support Tool/LG Suite (upgrade recovery), but that doesn't fix any of the problems. In download mode, there is a red ROOTED flag which doesn't want to go away :(.

I hope you guys can help me.
[G2 Q&A, Help & Troubleshooting] Sunandroid:
1st if you went to 4.4.2 it's a bit different: turn your phone off and let it be like this for 10 secs then press Vol- and Powerbutton until the lg logo shows up. release the keys and hold down vol+ and vol- then you are in the factory-reset screen. But since you are back on stock this will just reset your phone. TWRP or any other custom recovery isn't installed anymore.

Hey guys!

I have a weird problem with my LG D801 phone...

When I bought it the owner told me that was a D802 phone and it worked well but suddenly touchscreen stops working... so I have been reserching about this and found out that actually the phone is a D801 (printed in motherboard) flashed with a d802 rom so random touch problems may be because of this.

Then, I have tried to flash a KDZ of D801 by LG mobile support tool but not success it stops at 2%...

So... I have tried a LG FlashTool with the D801 TOT from this forum and get crossDL error I went across this searching here by changing the model with a HEX editor so thats no problem anymore but, when I try to flash with flash tool now it begins and suddenly stops at: LAF: BIN_USER_MODE reporting the error "Erase command failed"!

Any idea?? how to pass this weird error? there is other way to flash the D801 correct TOT or to force a KDZ with no errors? Thanks in advance!

Latest Firmware: D802T20D_00
[G2 Q&A, Help & Troubleshooting] raulx222:
Good.

Now you need to flash the downloaded firmware(D802T20D_00).

Download this tool: http://xdaforums.com/showthread.php?t=2797190 (you also need the usb drivers, you can download them using the links from this thread)

Open the tool (LG Flash Tool 2014) and from "Select KDZ file" select the downloaded firmware. Do

not

make any other changes in tool.

Now plug one side of usb cable in PC, power off your phone, press and hold volume up button and plug the usb cable in phone. Now your phone should enter in download mode.

From LG Flash Tool press CSE Flash (this will erase all your phones data, eventually take out your SD card just in case), then press the "START" button and wait until the process is done. And that's all, your phone should work again.

For root use towelroot, ioroot or stump root. But about custom recovery I don't know, I didn't even know about D802T until now and AUTOREC may not support D802T and that's why you were stuck in TWRP.

EDIT: Oh..I see there is a version of AutoRec for D802T..that one you used last time?

Thanks Sunandroid! I can get into recovery now, I guess I was too unpatient and tried it immediately after I turned off the phone....

I will try your solution for the Knock on too, but I really want to remove that "ROOTED" in Download Mode. Do you know how I can make this disappear? As I said, I already tried flashing a stock rom :).
[G2 Q&A, Help & Troubleshooting] Sunandroid:
That's a known issue and LG usually doesn't give a f*ck about it. But you can remove it anyways this way: http://xdaforums.com/showpost.php?p=56452984&postcount=16
[G2 Q&A, Help & Troubleshooting] raulx222:
Sunandroid is right xD. I have warranty and I send my phone to service with stock firmware but with broken download mode and they didn't say anything, anyway they reflashed the firmware to have a working download mode. When I received the phone I checked the download mode and it said "ROOTED".

Anyway that "ROOTED" status isn't triggered only by root. In KK update it's missing the root checker tool files, so it automatically says "ROOTED", and even if you didn't rooted your phone but you updated the firmware with LG Mobile Support tool then you will have the "ROOTED" status.

You can remove that status by manually copying the rtc files on your phone, or flash JB firmware and take OTA until KK. But at least on D802 OTA will broke the Download mode.
[G2 Q&A, Help & Troubleshooting] Hyp11:
But when I use the LG Mobile Support tool again, the ROOTED status will reappear (even when I use the rct method)? If LG Support doesn't care, I don't care. Thanks a lot :)

Edit: I tried fixing the "Knock on" using a lot of methods (Update Touch Firmware, Touch Firmware Upgrade, Motion Sensor Calibration, Touch delay), but still no luck :(. I am very sure it is not a hardware problem, since it worked before flashing the phone. I am using the international d802 with d80220c firmware.

I am paranoid about a strange app, i need some help.

Hello, sorry for being such a noobie but... i have rooted my LG G2, and today i've installed a strange app, first i thought it's GTA San Andreas, but i didn't look at the file size, which was way too small... and yeah... it asked for root permission and i granted it( although SuperSU showed a red sharp icon, i am not sure it granted the access or not) and when i opened the app a chrome browser opened up, but AdAway blocked it so it didnt load... and i closed everything and removed the app,then i did a scan with Avast and it said it was a fake app[trj], and it deleted the .apk i downloaded. I am usually a very paranoid person haha, so i am very stressed that it somehow gained root access and fiddled with my stuff. I will upload some screens and also the .apk file. Can you tell me what the .apk actually does ? Is there a way to decompress it and look at what it actually does. Because it's not a game for sure, i am really curious what is its purpose.I am sorry!But i am really concerned, can you help ? I've made a .rar, be careful though... i also added some screenshots of the download. Thanks!

Well I already started a thread for this specific question as I didn't see this forum thread before.

[Q]What does BUMPed really mean?

http://xdaforums.com/android/help/bumped-mean-t3029631​
[G2 Q&A, Help & Troubleshooting] Art Vanderlay:
This is the original bump thread.

Its a method of signing boot and recovery images so any custom image will boot on a KitKat bootloader.

In the dark ages (3 months ago) the only way to have a recovery on our g2's was to downgrade our bootloader so we could run the Loki hack on our boot images as we don't have unlocked bootloader. KitKat patched Loki so we had to use jellybean boot images with our recoveries this whole time, through autorec.

Now with bump, all we need to do to have a recovery is to bump a kernel (stock or custom, it doesn't matter) and recovery image and flash them via fastboot or DD commands.

I hope this helps a bit. You can have a look at the open bump thread thread as well to clarify it a bit more. Its a good read
[G2 Q&A, Help & Troubleshooting] d00lz:
Thank you so much, great response (what else would I expect from someone from Melbourne ;)) Feel free to reply to my thread and I will give proper thanks.

Is this something I should worry about as a user, or mainly for developers? I used AutoRec which resulted in downgrading my bootloader to JellyBean, is this optimal or should I consider getting the KK bootloader onto my device?

It's possible I might have a completely wrong idea of how this works, however I will scroll through the forums you linked me too, thanks once again.
[G2 Q&A, Help & Troubleshooting] Art Vanderlay:
No worries. As a user you don't need to worry about this. It'll probably just overcomplicate things. Custom Roms and kernel will always have Loki support so just use autorec if you want. If you're like me then you wanna be on the latest firmware and learn more stuff and yada yada.

Either way is fine though.
[G2 Q&A, Help & Troubleshooting] dosada:
Come on guys, there must be someone who can help. So far i have installed drivers and set the port to 41. The recovery starts but stops with connection error on the pc. The phone itself does not do anything.

Is there any "universal" 32GB Rom i can use as i have no idea what is on the phone? On the back cover it says LG-D802 and 32GB, there is an IMEI but it only has 14 digits???? I can't access anything on the phone itself to figure out what it really is
[G2 Q&A, Help & Troubleshooting] d00lz:
I would enjoy being on the latest firmware and being up to date with LG development. So right now, would this work?

1. Flash latest Australian KK firmware (D802T20D_00.kdz).

2. Install BUMPed TWRP recovery. (not sure how I would do this without AutoRec?)

3. Flash KK_Baseband_D802.zip

4. Flash CloudyG2_2.2.zip

5. Flash DorimanxKernel9.9.zip (Which I believe is bumped)

6. Reboot.

Would this land me on a stable working CloudyG2 with KK bootloader?

Really hope this thread is noob friendly :confused:.
