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?

Try SRK tool 2.1.
... if that does not work try flashing official firmware with TOT method( you will be back to stock)

Guys, I was an idiot about this, but I am at the end of my rope and could really use some help to try to fix things.
Here is what I did incorrectly:
Used TWRP to flash the wrong ROM
Created a backup in CWM format, not TWRP, so I can't restore it.
I have tried the three major methods on these forums multiple times to try to unbrick, with the following results:
Flashing official factory firmware with LG Launcher got hung up at the 12 s mark (when it transitioned to the "downloading software" step) for upwards of 15 min before I exited
Using the KDZ method seemed to work and actually got me really excited! But the "firmware update" progress bar on the download mode screen didn't move and a reset only ended up back at TWRP
Using the TOT method also appeared to start to work, but it failed because the build/dll didn't match. I have the VS98011A_01 version and used the TOT that I found in the thread.
Any help would be greatly appreciated.
Do you have the LG bootlogo coming up, if so try this:
(Something similar happened to mine, and I hope this will help.)\
Turn off phone, then when off, hold down power and volume down button until it reaches the LG logo and then release and hold it down again, if that doesn't work, when just hold it down until you see a screen that says something like: Hard reset/ factory reset. For me it took me to my recovery screen, where I just flashed a older ROM onto it, and you should be fine. I then later flashed a recovery file. I hope this helps, and if you need it any clearer, just reply :good:
Also from reading this, try flashing another ROM, if you have one present on the device, which will then allow you to boot-up then restore.
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. : (
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.
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.

Thank you so much for the advice! it had been so useful that I managed to get into recovery!
You saved my money, because I was starting thinking about a phone's forced change
I came back to cloudy because I wouldn't find myself in this situation once another!

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.

if there is read the go back to stock in the general section.. read and if cant find answer then ,ask in the thread..
and be especific everything pc and phone..
Hi,
I've looked everywhere before writing this so please forgive me as I saw there are a number of threads similar to this but couldn't find an answer.
Have rooted the phone a few days ago and flashed the Alexis Rom Oreo2.1S9PORT. As I had several apps that where acting up (no MIcrosoft Active Sync, no Outlook notifications among other things) I made a bit of a mess of it and decided to reset the phone by erasing all contents. As I went to boot up again the phone was in loop.
It goes on download mode and have tried with ODIN to reflash AP, BL, CP, CSC read everywhere looked on youtube but Odin fails each time. I've downloaded samsung drivers and firmwares to have Samsung Oreo back but to no avail.
Could someone please give me a hand in restarting the phone somehow? It's now in loop and I will wait until it dies down from battery failure as suggested in some threads in here.
Sorry to pester you.
Newbie...:crying:
latest ODIN screenshot. I don't know what more to try...please help...
Can you boot into Recovery Mode?
(Power off your phone, than hold: Bixby + volume up + power on button until you see the recovery mode)

No unfortunately. NOw the phone is battery drained.
THis is the Downloading mode. I can't think of what to do unfortunately. I've tried 3 or 4 firmwares as well.
Since I deleted through the phone system reset and not through TWRP (which I've now lost obviously) what would be the best way to reflash the mod (or the original Samsung one for that matter)?
ok I thought I made some progress, I've managed to reinstall TWRP and flashed again the Rom, Rom fix, and AOD fix. I was able to check the options of the Rom and the ROm installed succesfully. As I went to reboot I got stuck again in a loop with the SAMSUNG logo flashing continuosly. I can feel I'm close to a solution, could you point me in the right direction please?
The continuosly boot-loop could be the firmware doesnt match the Rom.
If you are game, try installing Renovate Ice: https://forum.xda-developers.com/ga...ovate-ice-g950-g955-android-7-0-aqdg-t3598040
Click the orange colored RENOVATE ICE WEBPAGE link.
From the menu choose FIRMWARE, download and flash.
Then download and flash R.Ice rom - follow the How to Flash guide

Thanks a lot. I managed alone 5 minutes ago. Reflashed the TWRP, then the Oreo ROM, and then the samsung firmware... result now I have a working fresh empty Samsung S8 with all Samsung apps... I now know how to do it. :laugh::laugh::laugh:
