Help please. - Sprint LG G2

I rooted my Lg G2 sprint version and everything went fine. Then i was an idiot and used TWRP manager to install TWRP, and recovery broke. It booted into Demigod Crash Handler. Next I really wanted to install CM, so like an idiot I used FlashFire to do so, and now my phone just boots into Demigod Crash Handler. Also i can not boot into Fastboot. Download mode doesnt boot fully, it just gets stuck on the screen that says download mode, and my pc doesnt recognize the phone at all. Please help.

can you send me a screenshot on where you are maybe i can help

i did, same problem, phone keeps restarting after samsung logo
maybe it sounds stupid, but why don't you try flashing recovery image and see if it boots you to the recovery?
or maybe you can logcat and look what made it boot loop... just my 2cents
i also noticed that when turned off and i plug in charger i dont see the battery screen to show that it is charging

i think that somehow you mess with some partition. try different stock trough odin, if it doesnt work send to samsung services
I had the same problem.
Seems like there is no way to solve the problem.

Hope you will get you phone repaired too.
Good luck.

I'm attempting to use LGNPST but it wont show up under the com port thing. i can get into download mode however, when i try to turn it on and get into recovery, the screen just lights up. no google logo, no boot animation of any sort. i was running dirty unicorn and called someone, the call just like...ended and i thought maybe my EFS was messed up because my data wasnt working. i tried to restore it in freegee but it said it couldnt. i tried to reboot the phone, but it wouldnt boot back up. Help, asap please.

Nasty Bootloop after Flash on Sprint G2

Last night I installed geefree on my phone from the app store and used it to install TWRP. I downloaded a nightly CM11 and an appropriate gapps. Using geefree I rebooted to recovery (never figured out the button combination to boot to recovery "naturally") and installed both of the zips. This could be where I made my mistake, I installed both at the same time.
Now my phone loops, displaying the LG logo for a few seconds, then shutting off and rebooting before repeating the process. I can't seem to get it to go into download mode or the recovery menu. I've tried power+up, power+down, down+up and each of those while plugging the device in, etc. I can get the device to a hardware key control mode, though it doesn't seem too useful.
How can I save my phone? This forum has been a great resource in the past and I'm very grateful for the many tutorials I've followed rooting other devices. Hopefully you guys can save the day once again!
Volume up plus power is how to access recovery on sprint.
What stock sw version were you on before you flashed cm?
Did you wipe data before flashing?
Sent from my LG-LS970 using xda app-developers app
I was using stock 4.2.2, I believe. I didn't wipe the data (shame on me), a bad habit that I picked up from my first rooted device, the Samsung Moment. It didn't ever matter on that one, afaik. Thanks for the reply!
Edit: Volume up and power whether plugged in or not takes me to the hardware key control mode screen.
Second Edit: http://forum.xda-developers.com/showthread.php?t=2432476&page=35 I also found this thread where someone seems to be experiencing similar issues and they fix it with "LG Utility." Is that a PC application? It's a little vague to google, but I've been trying!
I have a bootloop issue every time i flash a rom i have to wipe all but sd flash roms and gapps the i do a restore from twrp and oly restore my boot image only and they boot no prob
I'm kind of starting to suspect my power button doesn't work at all for whatever reason. I have a lot of difficulty getting the phone to shut down, then it doesn't seem to easily power up. It's a strange collection of problems. Would a Sprint repair place be able to fix this?
If they have parts on hand if not either a swap out or a sendoff
Same problem here - bootloop and no download mode - CWM works! - urgently need help
I guess I have the same problem as InlineFourPower (apart from that my power-button has no problem).
I am stuck in bootloop since I tried to upgrade to Kitkat a few days ago. Now I can´t get into download mode any more, nor into fastboot or anything else. Only CWM works.
From within CWM I can successfully flash ROMs but that doesn´t help, since afterwards I am still stuck in bootloop. It is possible, however, to push files via adb-commands while I am in CWM.
Does anybody have an idea how to go from here or how to get download-mode back?
Device is recognized but can´t be mounted - bricked forever?

I tried a few things on Linux.
After terminal-command "ls /dev/sd*" when the device is unplugged from the computer I get "/dev/sda".
When the device is connected via USB, I get: "/dev/sda /dev/sdb"
So sdb is my LG G2.
So I went on to the next command: "gdisk -l /dev/sdb"
As a result I get: "Problem opening /dev/sdb for reading! Error is 123."
Does it mean that the phone isn´t mounted or what? Now I´ve connected my phone to another Linux machine with the same result. It is recognised (p.e. as sdd), but there is no sdd1. Seems as if it is recognized, but can´t be mounted. Does that mean my device is bricked for good? That´s it?
to get the phone into download mode you have to plug the usb cord in and hold VOL+, so to get this right as I have a case on mine, plug the usb into the phone first then hold VOL+ and plug into usb port on the computer.
it does take a loooong time to power down the phone with the button when stuck in a boot loop, just keep holding it until it shuts off, it will shut off eventually!!
plug the phone in while in download mode to install drivers and set com ports, then unplug before you begin your flash with LGFlashTool, hope this helps you out.

Thanks Cronic2009 for your advice.
There are, however, szenarios where download-mode is not accessible any more. Neither by using the hardware-keys, nor by using the adb-command.
After four days of resarch and a lot of trial and error, I finally unbricked my F320L using the two adb-commands outlined at the beginning of that thread: http://forum.xda-developers.com/showthread.php?t=2451696
Worked like a charm.
Thanks everyone for your advice.
no problem buddy, glad you got it figured out, good luck to you from here on out!
FYI, that link doesn't work
I just wanted to ask anyone who might know, since the bootloader of the LS980 is locked, we cannot "break" this correct, so no matter what commands we decide to run through root, we cant touch the true bootloader there for LS980 fail safe? (Besides Acts of God, EMP, ect)

Thanks for letting me know. I corrected the link in my previous post.
Be sure if you use a aosp based rom to flash the ZV8 modem. Your can use dr87 or furnance kernals after you flash the zva modem althought i have encountered soft brick due to this.
so i'm having this exact issue and i don't know how to get out of it. i just need to transfer the radio to my phone somehow but nothing shows up under adb devices. i'm trying to the lg mobile support tool now. its downloading the software. but if it doesn't work does any one have any fixes?

After using tot and flash tool to get back to stock, did you try going into stock recovery and do a factory data reset? I know it sounds stupid especially after a tot but try it. Couldn't hurt

Borderline noob here, so please bear with me...
I have been using TWRP 2.7.0.0 to do all my work, and I was able to get the Lego ROM installed with ZVA. I got into too big of a hurry and forgot to make a backup of stock. I've also been unsuccessful in trying to install ZVC modem and firmware. Thankfully ZVA works as does the LEGO ROM, but I'd like to have stock there to access as well. The stockZVC that's on the Android Development page has been getting stuck (bootloop?) on the Sprint Spark logo. I've done TWRP's factory reset with no success. Any help would be great.
Thanks in advance!
Yes sir I've tried that and more to no avail is there anything I can do through adb I'm on stock recovery phone doesn't stay on long enough to install anything

Bricked d855 16 GB No download mode

Hey All,
I have searched the forum for this but i dont seem to get the same issue. And i dont want to make things worse, so i post it here. Hope you guys and galls are able to help.
So what happend. I wanted to flash back my G3 d855 16Gb Eur model.
Something allong the way went wrong, and i dont know what. All i know is that when i came back my phone was turned of. And my pc gave a failed message.
Now i cannot get in to download mode anymore. It gives me the LG boot logo and that is it.
When i want to enter download mode i get the download mode logo, with in the top left corner a verification error.
It goes quite fast so i cannot get the exact message. Can anyone point me in the direction of a fix. Ore is it indeed really dead?
Hello and thank you for using Q/A,
if you can't enter the download-mode, your mobile is dead. You may flashed a wrong firmware and the bootloader was overwritten with a wrong device.
Can you enter into Recovery?
Kind regards
Trafalgar Square

Can you reboot your phone into recovery mode (If it is already rooted and custom recovery installed).
I also faced a problem like that. In my problem when i reboot into download mode it took me to fastboot mode with 4 to 5 commands on left upper edge. If you can boot into that "fastboot" mode then tell me so i can help you better.
If you can't see anything like above then tell me that too i will try best to help you get out of this problem>>
No I don't get those options.
I get some kind of miss match error
exact error is:
boot verification failed
cause mismatch_sig_len
Hey All,
Just want to let you know, that i have been struggeling with my phone for two weeks. Offcourse not 24/7. But it is back alive. I managed to do the wiretrick and i was able to load up the Qualcom 9008 driver. After a long struggle i even managed to get the phone reconized by board diag. From that on it was easy to flash back all partitions. And download/firmware update mode was back. After this all i was able to flash the KDZ file.
I then lost my IMEI, but i backed up my EFS and all other importend files in the beginning. After rooting and flasing my EFS all was back to normal.
So ... i quess the d855 is indeed unbrickable

Probably hard bricked my K420n using service menu

So, like in the topic, I were using 'service menu'. Everything was good, until I found 'AAT' option. When I entered it, notification appered: Press ok to enter AAT. Phone will reboot. So I pressed ok, on down message appered: 'enter AAT' and phone have rebooted. From now, phone didn't want to boot, it was stuck at LG logo. I wasn't really worried, because I knew I had a backup of system and data in case something worng happened. I entered TWRP and restored everything BUT system still didn't want to boot. I tried to restore second backup (without Xposed) but same result. Now I started to worry that I killed my phone.
Also phone still goes into download mode but I think that PC doesn't detect it because I hear only characteristic Windows 10 plug in sound and nothing more. So what do I supose to do now?
Also what is AAT? And why it killed whole system

Are you sure LG Drivers well installed? They might not have been and that's why your device isn't recognized. If your device gets recognized while it's in download mode, you can try these guides:
LG Bridge: https://forum.xda-developers.com/lg-k10/how-to/guide-unbricking-flashing-firmware-due-t3380529
LG UP: https://forum.xda-developers.com/lg-k10/how-to/flashing-firmware-using-lg-t3517839
Finally, after 5 hour tough battle with my phone, I made it to boot up.

Flash ROM 5.1.1 (for me (K420n), flashing ROM 6.0 didn't work - I had to update to 6.0 earlier) until phone boots up. I think that I used this ROM: https://forum.xda-developers.com/lg-k10/development/stock-versions-model-lg-k10-t3457319
You can also try to recover/flash via TWRP but this method didn't work for me.
