I had the same issue and this is what @bender_007 had me do. (All credit is his.)
READ IT ALL FIRST!!!
If you can't get into TWRP you can't do this... I don't have CWM so I don't know if it works with that...
1) Download this: https://www.androidfilehost.com/?fid=95916177934554346
2) Get into TWRP and connect your USB to your computer. See if Windows recognizes it as an ADB device (get it do so if it doesn't) and use
Code:
adb push ls980_unbrick.zip /sdcard/
to get it onto your phone. (If you rename the file use that name.)
3) Flash it in TWRP. Unplug your phone.
THE FOLLOWING IS IMPORTANT!!!​4) After flashing the file DO NOT REBOOT, go back in TWRP to turn the phone OFF.
5) Hold Vol Up and insert USB into your computer AND KEEP HOLDING Vol Up.
6) You should see Download mode appear. Flash with LGFlashTool.
7) Profit

Probably you soft bricked your phone. I got into a similar situation when I applied OTA after root. Dont worry, its very easy to recover your phone. It should be able to boot in Fasboot mode. If it does, follow follow this guide:
.theandroidsoul.com/how-to-unbrick-asus-zenfone-2-works-on-ota-fail-too-82039/ (Add www at the start)
Download the latest pre-rooted system .img from here:
mega.co.nz/#F!k4MHiAgL!dVuOKeH3eokcwPSNI79ffw
Download the stuff needed and then just follow the guide. Hopefully you recover your device. Best of luck!
EDIT: Forgot to add but did you install the adb drivers? Probably thats the reason Fastboot and adb dont detect it. Or did you go into the fastboot mode in the phone? If not, do that first. To do it, follow these steps:
1. Power your device down.
2. Press and hold the power and volume up button.
3. Release the power button when it vibrates.
4. Release the volume up button once the ASUS splashscreen appears.
5. Now the device should be in Fasboot mode.
6. Then connect your phone to your PC (dont forget to install the drivers!) using the USB Cable and go to the folder where the flashtools are.
7. Hold Shift and right click > then click open command window here
8. Type "fastboot devices". Enter the command two times. (Cause the first time it will start daemon or something like that)
If your device shows up, congrats! You are in fastboot mode and it is working.

now what do i do
i do not know what ferwere i am on and my recovery is broken how to i get it up and runing

Once happened to my zf2, what i did is formatting cache from the adb then my device could be detected, thus i could enter the recovery mode

Hey,
Could you please help me (or anyone for that matter).....I've soft bricked my phone and I'm a little weary about following any other steps incase I fully brick the phone.
I have a Zenfone 2 that was CN Z00A 2.20.40.63 , I tried to root because random chinese apps kept downloading on my phone and obv it soft bricked (kept looping at boot).....since then I have tried a lot of stuff without luck and my brain is fried from all the information.... I went to the recovery mode but ADP couldn't find my phone and then I loaded a recovery image on my SD calling it MOFD_SD.ZIP but that didn't work due to signature verification error. Now after reading what you wrote I can see that fastboot is recognizing my device....I would go through with the process but I'm afraid if I screw this one up it could be the end of fastboot working and therefore me being royally screwed.
Since my phone was naturally CN Z00A 2.20.40.63 I'm wondering if the pre-rooted images on the site you mentioned above will work? There is no download for CN Z00A 2.20.40.63 and I want to know whether it's safe to use CN Z00A 2.20.40.61 (or a WW image) or whether I have to try another option (if you have any suggestions).
If anyone could reply with help it would be greatly greatly appreciated.

Well, I'm not sure if it'll work but check this out (Scroll down to No. 4 - Changing from CN to WW version):
forum.xda-developers.com/zenfone2/general/asus-zenfone-2-flashing-recovery-mode-t3096596
I'm no expert, but to be honest the state your device is in, I don't see any other options. Because when my device (it had WW firmware) got soft-bricked, I followed the guide by androidsoul and it did recover my phone. Not sure about yours since its a CN one.
If you like living on the edge and are really desperate, go ahead try this out, if not, better wait for someone with more knowledge then me.
EDIT: I forgot but since ADB isn't working, you can't use this method. So the only option I see that you have is flashing a pre-rooted rom.

Secure Booting Error! Cause: boot certification verify

Good day mate. My brick phone is F460S variant. I got this error when I tried to go back to Lollipop using Lg flash tool 2014, it got stuck on 5% and remove usb cable and start again, after that I got this error Secure Booting Error! Cause: boot certification verify.
No download mode
No recovery
anyone can help me please?:crying:

anyone?

You have triggered the downgrade QFUSE. There is nothing you can do apart from trying to unbrick it like it was dead, but that's not guaranteed to work. You should have researched more before attempting this. My prototype doesn't have a QFUSE, so i am free to downgrade via TOT to kitkat or lollipop.

I second you on this. I just uninstalled MultiROM and got the secure booting error. Depending on the ROM you have, find a bumped kernel and flash it. Most of the kernels on XDA are pre-bumped unless the developer states so. Boot into recovery, tutorials on the internet, then flash the kernel and voila.

if you can use twrp or you're able to flash, use mr_bump.zip: https://mega.nz/#!DNwhRBrK!Ki6zIzXca0KjPShi6L2oaCYIr0CkmH8sEymEt-0Q3ys

Get you G3 to fastboot mode. Hold volume up and connect it to PC
Open fastboot and adb folder in PC, ctrl+shift+right click and open cmd. Type fastboot devices...if ur device is listen then proceed, if not u did not do something cotrectly...if yes just flash laf img to your G3 and voila

I remember me that I was in the same situation:
No TWRP, no download mode, so i have use in pat this thread:
https://forum.xda-developers.com/showthread.php?t=1752270
And an other that i haven't found again (xda thread), in some lines:
=> download the last img file from: https://eu.dl.twrp.me/d855/
=> no download mode available so no possibility to flash manually twrp file from an LG Flash Tool
==> so setup an adb connexion to the phone, cp command to copy the img file on the sdcard or where you want
=> command: "flash recovery twrp-2.8.x.x-xxx.img" (https://www.xda-developers.com/how-to-install-twrp/
=> if it's as worked, you could reboot manually in twrp, make again the partitions if needed and flash any ROM.

Phone might be bricked. Need help to find a solution!

Hello everyone! Complete dumbass here!
I was following the guide to root my razer phone. I've had it for a couple months, and decided to root it. I followed the guide here https://forum.xda-developers.com/razer-phone/how-to/twrp-magisk-fullproof-guide-razers-wifi-t3756137
After a couple bumps in the road, such as fastboot commands not working, not being recognized, etc. I finally was able to unlock bootloader and install twrp. But it was #9 that got me stuck again.
"9.) Once in recovery, go to the install button, and select Install Zip, and select Magisk-v16.0.zip."
In recovery, adb devices and fastboot devices yielded no devices attached. Doing a search, I came across another forum post where it states the sdcard is encrypted and can't be accessed in twrp, and the fix is to do something like "Wipe>Wipe Data> Type Yes" and that should factory set the card. I did this and rebooted the device. I waited for a half hour for the animated PixelFloatingInACircle logo to be done with it's floating in a circle, but ended up going to bed and letting it die. Woke up this morning, plugged it in, got the razer logo splash screen with the orange text telling me of my impending doom, then went back to the animation. I let my dog out and came back and it was still on. I unplugged it and am letting it die again to see if there's another solution.
I'm wondering if anyone else came across this issue, and if so, how did they fix it? Any help would be appreciated.

Use the factory images in the developer portal. You have to manually install the fastboot driver or you won't see the phone in fastboot devices. After that you can flash_all.bat.
PS: if you just want root you can use magisk installer to patch the boot image (from the factory images) and then flash the patched_image.img. That's it, now you have root via magisk

The problem is when I try to enter download/recovery mode after charging the battery a little, it doesn't go to that menu. Instead, it skips right to the particle logo, and that's where it hangs.
The only guide I saw was the one I listed. Is there a guide for this magisk installer?(Ya know, in case I figure the first problem out, so I might try my hand at potentially creating another)

i think there is a way to hard reboot the phone, so you can do that and then hold the vol- key to start in bootloader mode when it reboots.
gonna check the correct buttons.
Edit: the button combination is power+vol+ for about 10-15 seconds, and the phone will reboot. You have to connect the phone via usb cable (before rebooting) to the computer (the only thing i'm not sure is if you have to have the fastboot drivers in the pc installed previously or if you can do it after entering fastboot) and just after the screen goes black while hard rebooting you have to release all the buttons and then press and hold the vol- button. The combination of vol- and the usb cable on boot seems to trigger fastboot mode.
I think the guide is in the guides forum, but the way it worked for me was without twrp:
- install magisk manager from this link -> https://github.com/topjohnwu/MagiskManager/releases/download/v5.7.0/MagiskManager-v5.7.0.apk
- push your boot.img (the easiest way is getting it from the factory image corresponding to the firmware you are using) to the sdcard
- open magisk manager -> install -> patch image only -> boot.img
- this will generate a patched_boot.img in /sdcard/MagiskManager
- copy that file to your pc
- go to fastboot and flash that patched image: fastboot flash boot patched_boot.img
- enjoy root, and you can use magisk hide for apps that don't like root

Tried this originally after I let it die the first time. It still boot to the animation logo.

Read the edit, I found that the trigger is having the usb cable connected to the pc. Try that, or you can also try to adb while the device is booting (particles logo). Sometimes adb is responsive even when booting. There you can try to adb reboot bootloader

As you already wiped the data partition, you should use the flash_all script. But yes, you can try flashing each partition

I moved the flash_all script into the tools folder and after a little while, the phone booted up into setup! After a couple taps, I've realized the wifi isn't working, which I know is a known issue. I'm gonna let it sit for the night and finish it in the morning!
EDIT : Soooo, I know I said I was going to bed, but I decided to fix the wifi issue, which in turn, also rooted my phone. I've downloaded the root checker, and it confirms it! Thanks so much Waiflih! You rock!

Hi guys, it seems I'm having the same problem and basically after unlocking my bootloader and flashing twrp to both of my slots I'm stuck on "Your device has been unlocked and can't be trusted" booting up infinitely.
The USB plug in and holding the volume - button doesn't bring up "download mode" and no matter what buttons I try and press on my phone my computer doesn't recognize ANYTHING connected to it anymore.
Bloodeagle, how did you manage to get "download mode" back onto your phone? it seems like mine refuses to do anything like download mode.

help returning to stock - H932

Help. I need to sell my H932 but the buyer is afraid of having root and not getting ota updates.
I was never too smart in regards to cell phones. But 2 weeks ago I had brain surgery and I'm even dumber now. I need steps written for a child. I have lgup but don't have a current .kdz. Its currently running H93220s.
Is Android 9 available ota?
Thanks in advance.

I already have lgup installed. While trying to install this new lgup, I get the message, "Error 1316. The specified account already exists." I'm assuming I have this version installed but don't know for sure.

I may be wrong, but if you're on stock 20s you're on the most recent update from LG.

I'm on a rooted 20s. I want to be on an unrooted, any version.
The instructions on LG's website say to hold the volume up button and plug it into a pc. I do that and it boots in TWRP. Typing adb devices from a Windows command prompt shows the V30 and it being in recovery mode. But starting lgup, it says, "There is no handset connected. Please connect a handset."
If I use TWRP to boot into the system, adb devices doesn't show any handsets connected. LGUP does see it but doesn't see the new .kdz file. And the phone reboots about once a minute.
If I boot into TWRP and do a default Wipe, it doesn't reboot.
What did I do wrong?

Doing a default wipe eliminates the OS from your phone so you don't have an OS to boot into. If you want unrooted stock and are able to boot into TWRP, you should be able to to just flash the flashable 20s kdz for the H932 w/o Magisk and that will put you back on stock. See the thread with instructions. I believe if you flash w/o Magisk that will also eliminate your ability to get back to TWRP. To root again I believe you'd have to start all over again so choose carefully.

Actually, you'd have to use the flashable 20s Stock ZIP, not the KDZ, if you want to flash it with TWRP. But that wouldn't restore stock Recovery nor Download mode (laf). Thus the new owner wouldn't be able to update with OTA or LG Bridge.
The best way to ensure complete stock is to flash KDZ, as you tried. Since your Download mode seems to be gone, I would flash the laf ZIP file in TWRP. You can find it in the Stock H932 ZIP thread and in the H932 root thread.
After that, follow the exact steps in the H932 root guide to get into Download mode, then flash the 20s KDZ using LGUP Refurbish Mode.
To be truly stock (and avoid the warning screen during boot) you have to also lock the bootloader, but you can only do that once all partitions are completely stock, otherwise you could brick the phone.

To be truly stock (and avoid the warning screen during boot) you have to also lock the bootloader, but you can only do that once all partitions are completely stock, otherwise you could brick the phone.

When I hold volume up and plug the USB into my pc, it briefly says Download Mode then TWRP goes on the screen.
I can't get the 20s.kdz to install using LGUP.
I truly appreciate all the help but this may be beyond my capabilities. (Brain surgery sucks.)

It's OK, people here want to help
Did you flash the laf ZIP in TWRP to fix your Download Mode? If not, that should be your first step. (If you end up losing TWRP too, it gets much more difficult.)
1. Download the StockLAF from this post by weakNPCdotCom's. Verify its MD5 to make sure it downloaded properly.
2. Transfer StockLAF.zip to you phone by whichever means (USB cable, SD card etc).
3. Boot into TWRP, either deliberately or by trying to get into Download Mode
4. Flash StockLAF.zip to restore your Download Mode.
5. Use TWRP to turn off the phone (I forget the exact command) and disconnect its cable.
6. Download and install LGUP from this post by runningnak3d. It's not the latest, but we know it works on H932.
7. Now try Download mode again: With the phone off, hold Vol Up, and plug in the USB cable that is connected to your PC.
8. If you manage to get into Download mode, launch LGUP and make sure it detects the phone.
9. Flash the H932 20s KDZ using LGUP Refurbish mode. Of course if you don't already have it, download it from lg-firmwares.com and verify its MD5.
10. Unplug cable and let phone reboot after LGUP (hopefully) completes flashing the KDZ.
11. Once (hopefully) in stock Oreo, tap Settings>General>About phone>Software info>Build number until Developer Options are enabled.
12. Enable Settings>General>Developer Options>Enable OEM unlock.
13. Turn phone off and unplug the cable.
14. With phone off, enter Fastboot mode by holding Vol Down and plugging in the USB cable. Plug into computer.
15. In ADB window, enter fastboot devices to verify ADB is working.
16. In ADB window, enter fastboot oem lock to re-lock the bootloader.
17. Use fastboot keys to reboot phone into OS.
18. Run Settings>General>Reset>Factory data reset. Do NOT use Master Reset (button dance) or the new user might trigger FRP/kill switch.
19. Done. Ship the phone to your buyer.
I'm insanely busy tonight, so afraid I won't be there for any follow-up questions. But anybody here should be able to help with those steps.
