Cant boot up LG G2 - G2 Q&A, Help & Troubleshooting

Hey
I was on ressurrection rom and tried to go to Cloudy G2. Since cloudy asks for kk bootloader i used http://forum.xda-developers.com/lg-g2/general/d802-bootloader-changer-1-1-jb-kk-lp-t3104380 with the kk file. Installed cloudy with no issues. Rebooted phone and never again saw the light...
Been for several hours trying to fix it, reading, but it's 04am and i cant see clear anymore. Its my only phone and i need it
So... it does not enter recovery... After flashing i try the combo keys and nothing
I tried to use use the LG Flash tool to revert to stock. I downloads the kdz file but when starting to upgrade it gives an error.
Also tried follow the thread about reverting to stock using lg flash tool 2014 but the same error happens,,, switched usb cables just to be sure...
ideas are accepted... thanks

hmm, maybe wipe your phone AND try another flash tool perhaps?

Can you enter download mode? Do you get black screen or LG logo?

I would wipe if I could get into something to wipe it

Yes. I did get into download mode. But it failed using LG flash tool

I got it figured out and will post on case someone needs it.
I was able to enter agAin in recovery by using the combo keys, power + volume down and when LG logo appears release them and press both volume keys. That did it. Once again in recovery I flashed again kk boot loader, wiped all and flashed cloudy Rom. This time went all ok. Go figure, I did the same thing

well atleast it works now eh?

its working great now.. even better now that today i managed to make my gps work and fix in 5 seconds

Kudos m8! Glad you fixed it. Its annoying having a great device thats not functioning or give us back enough for what we paid for.

[Q] [Q} Is my D802 Bricked?

Hi all
my D802 can't reboot with following method, could you please help me investigate how to fix it?
1. Can't enter download mode: I power it off, then hold volume up and plug in USB, but only the first screen shows up, can't enter the second one:
http://i.imgur.com/Kc4egAZ.jpg
http://i.imgur.com/jdCWBEW.jpg
So I can't flash kdz image.
2.I am able to access TWRP with official factory default( power+volume down to power on, when LG logo shows up, release power and volume down, then hold power.). But no matter I flash CloudyFlex which in my sdcard, or sideload flash others ROM, the cell phone will no boot up, always stuck at LG logo.
Any possible way to fix? Thank you very much.

not sure, I did few stupid things before.
1. I flashed LG G Pro 2 ROM here: http://forum.xda-developers.com/showthread.php?t=2673143 but it not good for me, so i went to recovery. but this rom replaced my recovery to a unknow one, not TWRP. when I was in this unknow recovery, my phone linked with PC via USB. PC found a lot of unformatted drivers, I did the most stupid thing: formatted one of them.
2. G Pro2 rom still can boot up, I flashed stock kdz, and rooted it with ioroot10, then flashed TWRP 2.6.3.3.
3. copy CloudyFlex_1.4.zip into sdcard through MTP mode of stock rom. reboot into recovery TWRP, flash cloudyflex, phone never boot up again.
4. No matter what rom i flash, always stuck at LG logo and the phone become hot.
sorry for my pool English.

Sorry man, I have no idea what you may have formatted then.. :/
I can't think of anything right now.. If you can't get to download mode and flash stock kdz again.. Then I don't know. I hope some one comes along that knows something. Sounds serious. I'll keep on thinking about things. But I have to leave the house now so..
Sorry.

[Q] Bricked? (VS980, bootloop)

Short version: Phone is boot looping at LG logo and when I try to volDown+power into recovery it gets to the factory reset prompt and I press power twice but nothing ever loads and the backlight just stays on. I'm guessing I no longer have a functioning download mode either because of the way these flashable bootstack zips we've been using on the VS980 ROMs mention that they disable download mode, so I probably can't use LG Flash Tool either. Bricked?
I had been on CloudyRom 1.3. I switched back to xdabbeb's VS980 ROM, the newest version with the 25B bootstack. As many people ran in to, for some reason after coming off of Cloudy, KnockOn doesn't work on other ROMs. I had tried to do this hidden menu trick to update the touch screen firmware which some people reported got the KnockOn working again. Long story short I was having trouble getting the hidden menu trick working while on the xdabbeb ROM, I went back to Cloudy ROM and tried to do it but that didn't fix it either. I saw people having success by going back to a purely stock ROM and doing the hidden menu trick from there.
Here is where I probably messed up, I had a backup from April of this year that I didn't have labelled/named well but I was certain it matched up with the last time I had probably been on a purely stock ROM when the VS980 finally got KK earlier this year, a backup I had made for the convenience of ever having to return to stock. I tried to restore this and that's where the trouble happened. At the time I figured worst case scenario would be that the baseband wouldn't match up and I wouldn't get a signal, but in hindsight I'm guessing it wasn't safe to try to restore this after updating to different bootstacks. Original KitKat rom was 24a I believe but I had just recently updated to 25B to use the newest xdabbeb ROM.
I saw a small ray of hope when I calmed down enough to remember the voldown+power sequence to get into recovery, but after reaching the factory reset prompt and pressing power twice to continue, nothing ever loads and the backlight just stays on, like my recovery is gone now too I guess.
And in a comedy of errors I'm guessing I no longer have a download mode that would allow me to use the LG Flash Tool through PC because these flashable bootstack files always mention that they disable download mode and I never worried about restoring it.
So, bootloop, can't get into recovery, probably can't get into download mode to work with LG Flash Tool.
Screwed? :crying: :crying: :crying:
Yeah, volUP + plug into PC just gets me fastboot mode.
Don't really understand why my recovery is gone, thought the button sequence to get back into recovery was the safety net to this entire thing and why I wasn't too worried. Was running TWRP.
I'm at the mercy of checking the internet when I have access to another computer because my phone was also my internet access on my home PC. Hoping someone can help. : (

[Q] Flashed wrong kernel!!!

i Was trying to get rid of the hissing noise on my
Lg g2 D802
i had TWRP installed
I read in a trhead that flashing the dorimanx kernel should fix that problem.
So i tried flash it, but instead of flashing the D802 i flashed the D800, i know i'm an idiot :/
I had a backup stock kernel but i think that's a wrong one too, again i'm an idiot
Now my phone boots into a black screen within the left top corner:
[2800] Fastboot mode started
[2850] udc_start()
i cannot boot into twrp anymore, it's basically bricked.
Can anyone help me recover my phone? i loved that thing, you will be my hero.
i promise when this is resolved i will never mess around with roms and kernels ever agian, i'm freaking out

Try to flash back to stock with kdz, as far as I am hearing this you kinda soft bricked it but not hard so it's still recoverable, you could also maybe try to flash your recovery back with fastboot since your in fastboot mode but I never tried that so I suggest you to go back to stock with kdz flashing
ye try enter download mode and follow this (use search) i think its volum up and connect usb to pc

Thank you for your reply, i tried to get into download mode, but failed every time, i can only press the power button for 5 sec and the Lg logo apears, then i get the same screen.
did this way?
Your phone must be turned off before starting the steps from this guide.
So, press power button and select “power off”.
Then, press the volume up button on your LG G2.
While you are holding the volume up button, plug in your phone’s USB cable.
Keep pressing the Volume up button until the download mode is being displayed.
Now the phone will install some drivers – it should take around 10 minutes to complete; the best will be to let your device install the mentioned drivers.

I did the same thing today by accident. I still can boot into recovery tho, TWRP. Copied the correct kernel file via OTG but it just reboots the recovery and doesn't install the kernel. Have you find any solutions?
EDIT: I actually managed to flash the right kernel and the problem is now fixed. Check everything before flashing something guys, caution

No Recovery Mode after upgrade CM 13

Hi guys, I have a problem with my LG G2 16gb. Today I have upgraded CM 13 with the last nightly. After having flashed Rom and Gapps I rebooted the system. The system runs but with some bugs (dialer crashes, screen doesn't wake up anymore when it goes in standby mode). So I decided to come back to the previous nightly, but I suddenly appreciated that I can't go in recovery mode.
I can go in download mode but both Flashtool and SRKtool don't work. I really don't know how to do.
I admit that I'm not able to resolve 2% problem with the fix.
I read that if I try to flash a firmware 10A then Flashtool should work, but I didn't manage to find a mirror of it.
Someone could help me? I Would be grateful
Same problem here. Flashed from cm-13.0-20160427 to cm-13.0-20160430 and now have the same problems. Using d802 with twrp-3.0.2-0
CM is booting, but has the same bugs as written above - no dialer, once in standby screen doesnt wake up any more.
I tried to reboot in Recovery from booted CM, the Phone is hanging with the "Reboot" on Screen. Same with normal reboot or shutdown. It just hangs. The Combination with the Volume Key Down & Power wont let me in Recovery as usual.
CM13 ist really awesome and nightly to nightly it was getting better, but the nightly today just went that wrong.
Would be nice if there is some solution to get the phone back working.
Thanks a lot for any advice or help!!!
Greetings,
Feldinos

I had some problems with booting into recovery as wel. CM13's latest nightly kept freezing my phone and I wanted to go back to my previous backup, but I couldn't boot into recovery from anywhere. Luckily I remembered that the button combination has changed with the latest bootstack I installed. It'sn now like this:
Force a shutdown by holding the power button. As soon as it goes black, press power + vol down, release as soon as the logo appears and then hold vol down + vol up. Then you should be able to get into recovery.

Thanks a lot for that information! Almost forgotten that i had installed an new boostack as i flashed the first CM13 nightly that was released.
I was now able to get in recovery and flash 04-27 nightly. Now my phone works normal like it does before i flashed 04-30.

When it reaches 2%, it suddenly appears a message telling me that my g2 is disconnected.
Unfortunately for modding, I installed w10. My pc has gotten better, but almost all the programs for modding don't work anymore. In addition to this, I didn't found drivers working well.
I'm thinking about restore w8.1.
There's a way to fix the problem of 2%, but I am not so prepared to use adb.. I'm aware about my limits

You're welcome As long as you can remember the different button combinations to get into recovery, you shouldn't be afraid to flash roms. Just never forget to make a nandroid backup before upgrading any rom!
If you start to flash roms, you WILL mess up at least once And this time, it wasn't actually your fault, CM13 messed up.

Phone bricked, help

Edit: I fixed it. I had the old KK kernel on the phone storage, so I went into recovery and just flashed it. Everything works now
I downloaded the DorimanX OTA and the went to update my kernel via the app (long story short - it downloaded a LP kernel & I use a KK rom). The phone went to recovery and then the screen went black. Now when I try to turn it on (by holding the power button) I get the LG logo for a second or two, and then it returns to the black screen. I can access both the recovery and download mode.
Can someone please help me solve this issue by walking me through the steps I need to take to fix this, please? Should I just do a factory reset?
