Your phone is in fastboot mode, not download mode. Small, but distinct difference.
Since you've installed a custom ROM, your bootloader should be unlocked. However, it may be a good idea to issue the oem unlock command through fastboot anyways. Use "adb reboot bootloader" and "fastboot oem unlock" to ensure that your bootloader is unlocked.
Now, since your phone is in fastboot mode, you can do one of two things: 1. Flash a custom recovery and restore your device to stock, or 2. Flash a custom recovery and continue using a custom ROM. Either way, you will need to install TWRP or another custom recovery image of your choice. The TWRP thread is located here: http://forum.xda-developers.com/tmobile-lg-v10/development/recovery-unofficial-twrp-t3239740 Since you're already in the bootloader/fastboot mode, all you would need to do is download TWRP and use "fastboot flash recovery twrp.img" and then "fastboot boot twrp.img" to install TWRP. Please note that the 'twrp.img' will vary depending on which version you download, it will probably look more like 'twrp-2.8.7.1-h901.img'. You can just rename the file or use the full file name in the fastboot commands.
Once in TWRP, you can flash whatever ROM you want. To restore your phone to stock, go to this thread and flash the .zip in TWRP http://forum.xda-developers.com/tmo.../lg-h901-stock-images-device-restore-t3241170 after doing the standard wipe procedure. :good:

I'm kinda in the same boat now except that I already received the replacement device. Need to re-lock the old V10, but adb won't recognize my device at all. Any more option when that's the case? I can get into both download mode and fastboot. Phone is recognized by LGUP in download mode, but not by adb in fastboot mode for some reason.
(I've verified connection and driver using the other V10, the other V10 is recognized just fine)

Yep. Your phone boots and everything, correct? Just factory reset it (Settings > Backup & Restore > Factory data reset). After its been reset, unlock it, turn on Developers Options, and enable USB debugging. After usb debugging is turned on, connect the v10 to your PC and be sure to hit "Always allow" when prompted by your phone. ADB should now be able to see your device.
If you can't get it to boot up, try restoring through LG UP/Bridge. I don't use any of LG's software, so I'm not sure what those apps can do and whether or not you'll be able to restore through them.
If nothing else, your phone is recognized in fastboot mode, so you can always manually flash the stock system images as well. You want to use the "fastboot flash boot boot.img", "fastboot flash recovery recovery.img", and "fastboot flash system system.img" commands After downloading the stock system images located in this thread: http://forum.xda-developers.com/lg-v10/development/lg-h901-stock-img-files-boot-recovery-t3238638
If you haven't ever flashed system images from fastboot, please read this first, as I am not responsible if your phone turns into a paperweight! https://developers.google.com/android/nexus/images#instructions While the instructions are for nexus devices, it works pretty much the same, except you'd want to use the individual commands instead of a flash-all script.
Hope this helps!

Thanks for the follow up! No the phone would not boot at all and kept stuck at boot loop. I ended up just doing the OEM Lock and call it a day, the old device just won't boot to anything at this point.
I tried fastboot flash recovery recovery.img but it's giving some kinda kernel panic message and I was never able to get into recovery. This reminds me of the time when my Note 3 eMMC was fried, it wouldn't give a device ID to adb.
I think I am in the same boat too. I've been OEM unlocked yet recently my phone won't keep the TWRP recovery and keeps putting me into bootloop. I can't install a ROM and only thing I can do is fastboot mode. What did you do OEM lock the device? I am hoping that solution will get rid of that message bootloader unlocked during the bootloop and then I can try and get it serviced.
Hi. I have had the OnePlus X for a very long time, and I have recently bricked .
Ok, here it goes :fingers-crossed:. I had a OnePlus X running CM13 with TWRP but a locked bootloader. I decided to try cyanogenmod recovery but soon realized it was terrible.
I was unable to flash img. files and the UI was unappealing to me. However at that point I was able to reboot into my ROM (CM13) with no issues. Knowing this, I thought that the only way I could get TWRP back was through a fastboot command (fastboot flash recovery recovery.img).
For me to execute that command, I needed to unlock my bootloader first, so I took all the necessary steps in the developer options settings menu. I then booted into fastboot mode and executed this command: fastboot oem unlock. This was my big mistake, as I read up after that you should not unlock bootloader on a custom recovery.
After executing this command, it booted me into recovery. I tried many times without success to wipe data and flash a rom zip via external sd card but they never worked. To make things worse, I was unable to boot up the device. Whenever I tried to power on the device, it booted straight into recovery. I am able to boot into fasboot and recovery, but that is pretty much it. Can someone please help me? I am willing to donate.
If you were able to flash the Cyanogen recovery with a locked bootloader you should be able to flash the official OPX recovery as well. You can download that from this link: https://s3.amazonaws.com/oxygenos.oneplus.net/OPX_recovery.img
Then you should be able to unlock the bootloader!
Or if @Tanner1294's doesn't help, flashing stock rom via fastboot will surely help..
PS: Don't ever flash anything on a locked bootloader.
Hello Guys,
I was trying to install OxygenOS 3.1.0 when I was on Sultanxda's CM13 but instead bricked the device.
What I did:-
1. Rebooted to TWRP and flashed stock OOS recovery and then clicked reboot into recovery.
2. Instead of rebooting in recovery my phone got stuck at the OnePlus logo.
3. I booted into fastboot to flash twrp.img but it says 'writing 'recovery'...
FAILED (remote: device is locked. Cannot erase)'
4. I repeated the same with stock recovery but no success and was not even able to boot to CM13 now.
Hence I was stuck on the OnePlus logo without any booting ROM or recovery and a locked bootloader (according to fastboot)
What I have already tried but failed:-
1. Tried to root with kingroot etc. (Before bricking)
2. Tried to unlock bootloader but failed because it has no recovery.
3. Tried to flash stock OOS 2.1.3-x
4. For now I used fastboot continue to boot back into CM13
Please help, I'm now stuck with cm13 without root and without any recovery installed.
P.S. I'm not even sure that if I clicked reboot then the phone will boot.
Thanks.
Okay, calm down.
Go to developer options and see if "OEM Unlocking" is enabled. If not, enable it.
Cool. Now enable USB Debugging, connect the phone to PC, open CMD and type
Code:
adb reboot bootloader
then
Code:
fastboot oem unlock
Download TWRP from the official website, rename it to recovery.img and then
Code:
fastboot flash recovery recovery.img
Now you have a recovery and an unlocked bootloader. Profit?
I hope this helps.

Thanks for your help,
But if you read my post then you'll understand that due to absence of a recovery I can't unlock the bootloader and hence cannot flash twrp

You don't need recovery to unlock bootloader, you need fastboot.

But in OnePlus devices the phone asks a confirmation through recovery recovery to wipe data and unlock

Any news with solution?
Hello guys.
I have been in the android world for a while, but just got this device.
I had tried to install twrp with no success. I already have bootloader unlocked by me with no issues, following a tutorial here. When I flash twrp it shows success but when I try to go there ñ, it just goes to miui recovery. When I boot directly from fastboot with:
Fastboot boot twrp.img
It goes there with no issues but of course, data is encrypted. So I want to install it in order to format my data and be able to root. Any ideas?
I researched and found that one way is to install a dev rom, but I really want to remain on stable one.
Thoughts?

Put a copy of twrp.img in your sdcard.
Put other copy of twrp.img in adb folder of your pc.
Type from a cmd with admin rights with device in fastboot mode connected to pc fastboot boot twrp.img and when you reboot to twrp slide allowing modifications and then flash your twrp.img through same twrp recovery
The first command will do that device can boot to twrp but it´ll not flash it in recovery partition.
The second action will flash it permanently onto your device.
Probably you´ll need to format data in order to can reboot to system again.

Thanks! I solved it after taking a look for a while. I do not have an sdcard, so I flashed it and then fastboot booted it, then I reboot recovery to make sure it was flashed and then formatted data. I worked flawlessly!
Hello
I 'm using Lenovo Tab 2 a7-10f
I tried to flash TWRP recovery throught fastboot.
But i didnt succeed before, so this time, i tried to enter command to open TWRP without need to install it.
___________
I entered fastboot mode via command
adb reboot bootloader
and yes, i did unlocked bootloader
___
then i used this command to put recovery in my tablet just to open that recovery
fastboot -c "lge.kcal=0|0|0|x" boot c:\twrp.img
______
i found this solution on this site
https://android.stackexchange.com/questions/86936/how-to-flash-root-zip-in-fastboot/102597
_______
And now, it is in bootloop, until i click both volume up and down , then it enters TWRP
_______
Tried to go in TWRP , Reboot > Power Off
And it shows logo and dont proccedd more, just stuck there and spining
Until i press both volume up and down, so it opens me TWRP recovery
________
Also tried to go into Reboot > System
But still same issue, not booting up at all
___
If i click Reboot > Recovery
Then it boots me back in TWRP
______
I tried already SPFlash tool before, but it doesnt detect my tablet, even if i have all drivers, and google drivers, and USB debbuging, i'm using this tablet for android app development, so it have all drivers.
_______
I managed to get my data from tablet.
I dont know what to do next.
Should i make some command from computer to boot system, using ADB, i know to use ADB, just i stucked in this weird bootloop.
_____
I'm thinking that i should flash stock ROM from TWRP while it is still alive.
Should i do that, i dont want to lose my data, i have many programs.
I dont care if i lose TWRP recovery, i dont need it after this experience right now???

If you flash stock can you resume control and appreciate with repatching of recovery

O, oh man, i just got shocked !!! By all this.
I understood that my problem is in boot,
because this command
fastboot -c "lge.kcal=0|0|0|x" boot c:\twrp.img
tells android that when i press power button, to boot into whatewer it is pointed to.
So this command tells android to boot recovery instead of normal system.
So i just reverted it in bootloader (fastboot) mode, by pushing command
fastboot flash boot c:\boot.img
So it booted up again ) , and also important, without losing any precious data. ))

It is true when people say that if everything fails in android, there is always a bootloader that you cant destroy.
And also here are commands for other partitions, in this way you can flash whole system without root or anything, for anybody who face this problem which is very hard to break without ADB, because i think even if i flash stock ROM it will boot recovery because somewhere deep inside, it is written from that bootloader,
Again, never joke with bootloader, if it dont support, it dont support and over, i dont want TWRP anymore.
Dont get in this trouble, mybe nobody will be able to fix it if he dont know how it happened.
______
Commands
_______
adb reboot bootloader (to go into bootloader)
fastboot flash boot boot.img (this is i used)
fastboot flash system system.img (this is ROM, like kitkat, or lolipop)
fastboot flash userdata userdata.img (this can be optional, it means full reset)
fastboot flash recovery recovery.img ( if on twrp , dont flash this thing if not cause problems)
