stuck on lg logo

I have followed the guide and was able to get into recovery/download mode.

I boot in download mode and by using LG Support Tool I was able to install (and here I did something very stupid) the OTA.

Everything went smouth no error and I was really happy, but then upon the reboot, here again ... stuck on LG log, no download mode not recovery mode.

The situation seems to be worst than before as Linux do not see my partitions, so I can not re apply the guide :(

If I run DMESG I get:

unbrick without wiping data?

Does the LG Flash Tool method described in the original post wipe the data?

Is there a way to fix soft brick without wiping the data?

I have rooted stock ROM (I believe D80020u with stump root) on my AT&T LG G2. Yesterday, my phone all of a sudden started showing one of my photos in the gallery in the background, like a wallpaper. I tried changing the wallpaper but it was still showing the photo. So I restarted my phone and it got stuck at the AT&T logo. The only "risky" thing I did was that I manually changed a value in the mixer_paths.xml in systems/etc to increase the volume of the headphone (which worked). But that was about 9 hours prior and the phone has been functioning normally.

I can go into the download mode or the factory reset mode. But I really want to keep my data as I don't want to loose all the photos that I took during Thanksgiving. Can anyone please help?

seems like you are not rooted. what is your firmware ? Might need to downgrde it or use autorec.s tool (ist line in op)
[AT&T LG G2] atrix4nag:
Sorry for the dumb question: I am on D80100d, once I root, install recovery as per OP, if I want to install latest ROM's (lollipop) can I directly install them or do I need to upgrade firmware before that?
[AT&T LG G2] epapsiou:
once you are rooted and have recovery go ahead and install ROM. No need to upgrade firmware. Infact once rooted and "twrped" you should not touch firmware (except to fix bricking /warranty)
[AT&T LG G2] xKadish:
Also, if you want to upgrade to a new ROM from your current ROM, always remember to backup and wipe everything EXCEPT internal storage. Then you can go on to flash your new ROM and gapps!
[AT&T LG G2] atrix4nag:
Thanks for the response guys... I will install Lollipop as sson as ROOT the phone.
[AT&T LG G2] DvineLord:
im on 20k firmware. i rooted with ioroot25 then autorec to downgrade bootloader and flash twrp 2.7.0.0. i later ran towelroot for the hell of it. i can never get official twrp to flash because they dont use loki_tool for some reason even on the latest builds. i was able to flash philz_touch fine since loki is done properly. philz_touch is also nice cause it allows u access to many more partitions then twrp. i did make the mistake of letting the phone take the ota update a couple times and bootlooping until i fixed the issue by zeroing the nessacery partitions and removing the system files used for taking an ota. i thought about flashing back to stock and otaing up to 20y to get the latest firmwares on the other partitions and the "knock code" update. then root with stumproot and bootloader/recovery with autorec. since i have been tired and stressed lately i did not flash back to stock. i since have flashed latest dorimanix kernel which has bump support and f2fs. i then discovered that blastagator created bumped builds of latest twrp. since that gives u latest bumped kernel and latest bumped custom recovery things felt a little better with this phone. i found out blastagator made a bumped kk bootloader which i flashed successfully. i also downloaded but havent flashed blastagator's bumped jb/kk hybrid modem.

at this point i feel like my phone might be prepped enough to flash custom roms. i am concerned about not having the "knock code" firmware update since dorimanix states you should update your firmware to it for latest kernel builds. i can verify that i can only make the phone sleep by double tapping the screen but not waking it. i can only assume that flashing latest firmwares might be required for future roms and kernels like on other devices.

since we now have a way to flash kk bootloader and jb/kk hybrid modem i wonder if there is a way to get "knock code" update and other important firmware updates without having to flash back to stock 20c then otaing up to 20y?

if i decide to flash a custom rom without "knock code" firmware update would i regain the ability to double tap the phone to sleep and wake it again? or is it lost to me until i flash back to stock and ota up?
[AT&T LG G2] epapsiou:
I have no idea what state your phone is in. You really went medieval on it.

I would say at this point try it. And if something fails go back to stock and then root through autorec.
[AT&T LG G2] Jammol:
You don't need the knock code update if you are on a stock ROM and flash the latest dorimanx.

Also not sure why you went through all those steps. Your phone was good to flash custom roms from the moment autorec was released. All you need it the right modem for the right ROM. I have both the aosp modem and the kk stock modem. I simply flash the appropriate one based on the ROM in using.

Always have a backup!!! Can't stress that enough. Get a USB otg adapter/cable and a flash drive. I keep mine around my neck so I can flash roms or fix a brick otg.

My current setup:

Installed autorec(was stuck on kk boot loader and needed downgrade)

Flashed blastigator newest twrp

Flagged cm11(latest nightly)

Flashed gaps

Flashed aosp modem

Reboot

If I want to go to an lg ROM I simply flash it and the respective modem and reboot.

By the way if you don't have the right modem for the ROM you're using knock on, rotation, proximity sensor and God knows what else, will not work. You must be on the right modem. Also knock off(anywhere on screen) is an lg launcher feature that is dependent on framework files only implemented on lg based roms. On AOSP/CM BASED ROMS only double tap status bar to sleep is available, unless you get the pro version of launchers such as nova prime or Apex pro.

I think this was the longest post I have ever written on XDA. Lol.

Dear Friend

i have problem with my phone D800. i buy used phone after OTA update Touch is not working correctly .. when i open phone then i see phone name is D800 now i trying to install D800 Firmware then problem is LG flash tool show me error . D802 to D800 failed .. plz help me

[AT&T LG G2] epapsiou:
I am assuming you have d802 firmware on d800. Flash tool checks phone with the file and fails if mismatch.

There is a flash tool that does not check the versions. You can flash d800 firmware using that. You will have to search g2 forums for that tool. It is lurking somewhere

[AT&T LG G2] Jamesyboy:
Is this method still viable for those on 80020y? If were going to downgrade to 20d via AutoRec, do we use Ioroot25? The OP makes it sound like you only need AutoRec.

New G2 User. Thanks.
[AT&T LG G2] jordant2:
For the latest firmware all you need is stump root then autorec. No need to downgrade and ioroot won't work.

I used this method recently for the y firmware. Worked just fine. Will update OP.

Please refer to the rom's( you want to flash) thread. Each rom has its own requirements. Generally you wipe system and factory reset and flash rom and gapps.

Hey I need help

I did root

And installed twrp

When I did wipe dada internal accidentally pressed

I try through the mount but failed to impress me

tenks
[AT&T LG G2] epapsiou:
So I am assuming you lost your ROM zip when you wiped internal SD. So a few things you can do

- Try restarting your PC and connect to phone when I twrp. That should work if you have all the drivers ( see OP for drivers)

- Try to mount USBOTG. TWRP supports that.

- Try adb. That should work if you have drivers and adb. Google if you don't know adb . OP has stuff on adb too

- If that fails start the process again. Go to stock(see OP) and then use stumproot to root.
[AT&T LG G2] yossefe:

[AT&T LG G2] ghostrider1597:
A lot of people that used autorec are finding that there knock on feature is not working.

This is because autorec downgraded your boot loader and the old one for most g2 phones don't support that feature.

So the easy solution I found out is...

Download the correct twrpx.x.x.x.img for ur model and flash it using an app called flashify. If u can only find .zip file for twrp, theming file should be inside the zip file.

Tested and confirmed on my LS980 on bell

You need to restore it to stock (see OP). But you will have to search for file you need. The one in OP will not work as it will think your phone is d802. Search the forum. There is a file floating around that does not check what phoen you have. That is the one you need. Make sure it is for d800

[AT&T LG G2] Superorb:
Is this guide still relevant? For example, it says not to use TWRP 2.6.3.3, but that version is almost 2 years old and there have been several newer releases.

I want to update to either lollipop or CM12/13. Ive rooted using stump root and installed twrp for recovery. I received the phone with d80020y loaded AND MY PHONE DOES NOT CONNECT TO A PC EVER SINCE I ROOTED IT although everything works fine (except the WiFi tether as the case for most d800s).

I'm worried because I've converted some system apps to user apps and vice versa using Link2SD to uninstall some apps(none related to system or with the android bot as the icon of the apk file).

Should I follow the procedures for flashing roms as for any other rooted d80020y (ignoring the above mentioned changes) or flash the stock d80020y.

Any sort of help would be a blessing (I'm too bored with KitKat )

Something that might be useful. When using Win 8 and you try to change the COM port.

You were lucky aaronDroid80. I used ioroot and freegee for rooting my phone and had isses with twrp. (TWRP would install with freegee but will not flash ROM's properly especially FLEX based ones).

Then a week ago i repeated the same steps (freegee, ioroot and twrp) on my wife's phone and same issues.

I have also seen lots of reported issues with 80100o on LG Stock based ROMs.

I would still recommend to go to 80100d.

But if you want to avoid that step you can try with 80100o firmware and restore to 80100d later if you experience issue

The problem comes in when trying to change the COM port to 41. I keep getting the error message that I don't have write privileges. Try it on both my laptop and laptop mini.. both running a version of Windows 7.

I'm not sure what the problem is, whether there is a setting in my phone that I haven't made active or something with my laptops.

I see that the new firmware is supported in IOroot22.. so I'll give it a go without the downgrade ...
[AT&T LG G2] epapsiou:
Issue with 10o is not the root. 10o will root fine with ioroot. The issue is that flashing custom ROMs with 10o is a hit or miss. (mostly miss)

But no harm in trying to do it with 10o. You can always come back to 10d with lg flash tool (if you can change port :) ).
[AT&T LG G2] aaronDroid80:
Thanks for the info. I have no intentions of flashing any LG based roms, so if that's where the issues are, then hopefully that's where they'll stay. I did read that a lot of people had problems getting twrp to stick, but that looked like it was back when the update has just come out. I saw very few current issues, so I gave it a try.
